Financing solutions for the MARINEWIND labs (UK, ES, IT, GR, PT)
Overview
The UK combines long-term revenue support, targeted capital grants for ports and manufacturing, state-backed investors, and blended public-private initiatives to accelerate floating offshore wind deployment and supply chain growth. These instruments work together to reduce revenue and construction risk for developers while supporting local industrial capacity.
Contracts for Difference (CfD)
This is the primary revenue support scheme for renewables, including floating wind in the UK. Projects bid in annual auctions (Allocation Rounds) to secure a 20-year “strike price = 271” contract. Starting with AR7 (2026), the government set aside a dedicated budget for floating offshore wind under an “emerging technologies” pot. This sliding CfD mechanism guarantees developers a top-up if market prices fall below the strike price (and claw-back above it), providing long-term revenue certainty. It has enabled the UK’s early floating projects ( Hywind Scotland) and will support larger Celtic Sea arrays later this decade.
FLOWMIS (Floating Offshore Wind Manufacturing Investment Scheme)
A £160 million capital grant programme launched in 2023 to upgrade ports and manufacturing infrastructure for floating wind. FLOWMIS aims to “support critical port infrastructure enabling floating offshore wind delivery”. In March 2024, the government selected Port Talbot (Wales) and Port of Cromarty Firth (Scotland) as primary recipients, with ~£60 million earmarked to expand quays, assembly areas, and deep-water facilities. These investments, co-funded by port operators ( ABP’s £500m at Port Talbot), will create hubs for manufacturing turbine foundations, towers, and subsea anchors, accelerating Celtic Sea and Scottish floating projects.
Great British Energy (GBE)
GBE is a new UK state-owned clean energy investment company (announced 2023–2024) empowered to co-invest in renewable projects and supply chain ventures. In 2025, GBE partnered with industry and The Crown Estate to inject £1 billion into the offshore wind supply chain. This public-private initiative (with industry matching government funding) will finance new turbine and blade factories, steel fabrication facilities, and port upgrades for floating wind. By leveraging GBE’s patient capital alongside private investors, the UK aims to build regional clusters of floating wind expertise and create thousands of jobs, while ensuring critical components (like cables and floating substructures) are made domestically
UK Infrastructure Bank / National Wealth Fund
The UK Infrastructure Bank (est. 2021) was expanded and rebranded in late 2024 as the National Wealth Fund (NWF). This public investment bank (capitalized with ~£28 billion) provides debt and equity financing for green infrastructure – including offshore generation, port upgrades, and grid reinforcement – with a mandate to “crowd-in” private capital. It operates as an “impact investor” at arm’s length from the government, co-financing projects that commercial banks deem too risky. The NWF (previously UKIB) has priority sectors like clean energy and transport, and can take minority stakes or offer low-interest loans to enable floating wind farm build-out and associated infrastructure. This ensures strategic projects ( transmission links to offshore hubs, or factory build-outs) secure funding and proceed on schedule.
UK Export Finance (UKEF)
UK Export Finance (UKEF), the government’s export credit agency, supports the offshore wind supply chain by providing loan guarantees and direct financing for overseas projects that use UK technology. For example, in 2025 UKEF issued a €146 million Buyer Credit Guarantee to back a 632 MW offshore wind farm in Taiwan, enabling British firms to win contracts for vessels, cables, and engineering services. UKEF has a target to mobilize £10 billion for sustainable projects by 2030, and has already financed over £500 million in offshore wind farms abroad. These guarantees de-risk international projects for lenders, indirectly boosting UK turbine and foundation exporters. Under its Clean Growth scheme, UKEF can cover up to 80% of loan amounts for foreign buyers of UK offshore wind products, thus catalyzing orders for UK-made floating platforms, mooring systems, and consulting services.
Offshore Wind Growth Partnership (OWGP)
A £100 million supply chain development program established by the Offshore Wind Industry Council in 2019. OWGP provides grants (typically £100k–£1m) and business transformation support to UK SMEs aiming to enter or expand in the offshore wind sector. It runs open calls for projects in areas like advanced manufacturing, robotics, and logistics relevant to offshore wind. By 2025, OWGP had supported dozens of companies via its “Fit 4 Offshore Renewables” and “Sharing in Growth” initiatives, helping them achieve required certifications and scaling up production. This ongoing partnership (delivered by ORE Catapult) ensures UK firms can competitively supply components (anchoring systems, cables, etc.) for floating projects. It complements larger government schemes by focusing on capacity-building and innovation at the supplier level.
Scottish National Investment Bank (SNIB)
Scotland’s state-owned development bank (launched 2020) offers patient capital (debt or equity) for projects aligned with its missions, chiefly the transition to net-zero. SNIB has actively financed infrastructure to support offshore wind – for instance, it provided a £50 million loan facility to redevelop the Port of Ardersier in the Scottish Highlands into a manufacturing and staging hub for floating wind (co-investing alongside the UK’s NWF). It has also funded vessel construction for offshore wind services and backed factory investments ( a subsea cable plant) that bolster the supply chain. With £2 billion initial capital, SNIB can take higher-risk positions that private investors avoid, ensuring that critical Scottish ports (and related enterprises) have the infrastructure to handle large floating turbines. Its focus on regional economic renewal means that remote coastal areas – like Orkney or the Western Isles – could see SNIB-funded fabrication yards and support bases for upcoming floating wind farms
The Crown Estate – Offshore Wind Investment & Supply Chain Funds
The Crown Estate (which manages the seabed in England, Wales, N. Ireland) not only leases sites to developers but also reinvests lease revenues into enabling projects. In 2025 it secured new powers to invest up to £400 million in offshore wind supply chain infrastructure. This includes a new £350 million Supply Chain Investment Programme for building or upgrading ports, factories and test facilities that support offshore wind. The Crown Estate is coordinating these investments with Great British Energy and the NWF to maximize impact. In addition, it operates a £50 million Supply Chain Accelerator Fund, which runs annual calls to fund early-stage project development and engineering studies (designs for floating substructure fabrication). By late 2024, the Accelerator had awarded ~£5m to 13 organizations and expanded its scope to include port infrastructure proposals. The Crown Estate has also directly financed pre-consent surveys in new leasing areas – for example, it funded extensive metocean and environmental surveys in the Celtic Sea in 2023. This upfront data de-risks floating wind projects (shortening development timelines and reducing costs) by providing developers with wind, wave, seabed and wildlife information before auctions. Collectively, these Crown Estate initiatives aim to alleviate bottlenecks (in planning and production capacity) so that the UK can deploy up to 5 GW of floating wind by 2030.
Green Industries Growth Accelerator (GIGA)
A £960 million government fund announced in late 2023 to spur domestic clean-energy manufacturing, including the offshore wind supply chain. GIGA provides grants or low-cost finance to projects that expand UK production of critical components like turbines, blades, cables, and floating foundations. It is a broad program covering multiple sectors (offshore wind, electric vehicles, hydrogen, etc.) with the goal of growing “home-grown” industrial capacity. For offshore wind, GIGA funding could support new factories for XXL monopiles or concrete floating platforms in areas like Teesside or Humber. The Autumn 2023 statement highlighted this investment as key to maintaining the UK’s leadership in renewables, noting it will “accelerate advanced manufacturing capacity in key net zero sectors, including offshore wind”. By mid-2025, the government expected GIGA to leverage an additional £90 billion in private investment over a decade. This fund works in tandem with the CfD market demand – ensuring that as gigawatts of floating projects are auctioned, UK firms have the factories and skilled workforce to supply them.
Public-Private Supply Chain Initiatives
he UK is increasingly using blended public/private financing models to grow its floating wind industry. In June 2025, the Energy Secretary announced a landmark £1 billion commitment to offshore wind manufacturing and ports, with half coming from government (via Great British Energy and The Crown Estate) and half from industry. This joint investment will establish new production lines for towers, blades and cables, as well as upgrade port facilities to handle assembly of floating turbines. Industry partners (developers and OEMs) are matching funds and collaborating with government through the Offshore Wind Industry Council. By aligning public capital with market players’ needs, such initiatives aim to prevent supply bottlenecks and keep project costs down. Earlier examples include the Offshore Wind Growth Partnership (industry-funded) and regional cluster funds. The 2025 £1bn co-investment, however, marks an unprecedented scale – it will help create several “world-class manufacturing hubs” around the UK’s coast, anchoring the floating wind supply chain domestically for decades to come.
Overview
Spain is assembling an auction-based regime alongside recovery grants, regional initiatives, export insurance and bank facilities to catalyse floating wind pilots and scale-up. Regional test sites and port partnerships are also important features of the Spanish approach.
Offshore Renewables Auction (RD 962/2024)
Spain has established a new framework to auction floating offshore wind capacity, aiming for 3 GW by 2030. Royal Decree 962/2024 (approved Sept 2024) set out the process for competitive tenders in designated marine areas. Under this scheme, developers will bid for seabed rights and a 20-year sliding Feed-in-Premium contract (similar to a CfD) that tops up market revenues to a fixed tariff. The first pilot auction is expected in the Canary Islands, which have strong winds and high power prices. However, as of mid-2025 the auction had not yet been launched – industry groups (like AEE, the Spanish Wind Energy Association) have urged the government to accelerate, warning that “nearly a year after RD 962/2024, no progress” has been made. Once initiated (likely in 2025–26), this auction system will be Spain’s main funding mechanism for large-scale floating wind farms. Winners will receive long-term price stability and exclusive grid access for their projects, mitigating revenue risk. The Spanish government also reserves the grid capacity and maritime space for auction winners by law, streamlining development. In short, the auction scheme is poised to unlock Spain’s significant floating wind potential, but timely execution is critical – Spain’s 3 GW by 2030 target is ambitious, and delays could cause it to “fall behind global leaders”.
PERTE ERHA & Recovery Grants
Spain is leveraging EU recovery funds to support innovative offshore wind projects and R&D. Under the PERTE ERHA (Strategic Project for Renewable Energies, part of Spain’s post-COVID Recovery Plan), the government dedicated €200 million in grants for offshore renewable energy in late 2022. These funds were split into sub-programs covering: pre-commercial floating wind pilot farms, open-ocean test platforms, supply chain improvements, and port adaptations for offshore wind. For example, one sub-program financed pilot floating platforms and turbines to be tested at sites like the Canary Islands and the Biscay Marine Energy Platform (BiMEP in the Basque Country). The 2 MW DemoSATH project – Spain’s first grid-connected floating wind turbine installed in 2023 – benefited from these innovation grants and other public support. DemoSATH (led by Saitec/RWE) received co-funding from IDAE (Spain’s energy agency) and CDTI (innovation agency), showcasing how PERTE ERHA and related instruments de-risk early deployments. Additionally, in 2022 the government announced €160 million specifically for port upgrades to support offshore wind assembly (via the program “Port-LaEOLMAR”), ensuring infrastructure is ready for larger prototypes. Collectively, these recovery-funded grants aim to propel Spain’s floating wind technology from demonstration to commercial readiness by 2030, by sharing the high upfront costs of first-of-a-kind projects and critical facilities.
Regional and Private Initiatives:
Beyond national schemes, Spain’s regions and industry are actively investing in floating wind’s development. In the Basque Country, the regional energy agency EVE launched a €2.5 million funding line to support floating wind prototypes and testing. This has helped companies trial scale models and mooring solutions at sites like BiMEP, a grid-connected open-sea test site near Bilbao. (Spain already hosts Europe’s first floating turbine lab via BiMEP, attracting technology developers.) In Galicia, the Port of A Coruña entered a partnership with RWE in 2024 to transform part of the port into a logistics hub for floating wind. RWE’s Letter of Support will guide upgrades so the port can handle marshalling and assembly of floating platforms, positioning A Coruña as a launch point for projects in Spain, Portugal and beyond. Meanwhile, major Spanish companies are investing heavily: Iberdrola and consortium partners are developing floating projects in Spain and abroad (using local yards like Navantia for fabrication); Navantia-Windar have built floating foundations ( for Scotland) and are expanding facilities; and Equinor–Naturgy have plans for floating farms off Spain’s coast. These private and regional efforts – ranging from R&D to infrastructure MOUs – complement public funding. They demonstrate market confidence and help build a domestic supply chain (ports, fabricators, engineers) ahead of the national auctions. Spain is also tapping EU-level programs: proposals under the EU Innovation Fund and Connecting Europe Facility are in play to support cross-border grid studies for offshore wind. In summary, even before the central government’s first auction, a multi-level coalition (autonomous communities, port authorities, utilities, and EU funds) is laying groundwork for floating wind – from prototype validation to port readiness and industrial clusters. .
Renmarinas Demonstration Program:
The Spanish government has run targeted calls to de-risk offshore renewable prototypes, often referred to as Renovables Marinas demos. This program (under IDAE and PERTE) provides grants for pilot projects in both floating wind and marine energy. It funded, for instance, the 2021–2023 deployment of the X1 Wind prototype – a novel single-point moored floating turbine – in the Canary Islands, and wave energy devices in Galicia. By backing these demonstrators (with grants up to 50% of project cost), Renmarinas helps Spanish technology developers bridge the valley of death. Successful demos can then attract private capital for scaling. The program also covers environmental monitoring around prototypes to gather data on impacts. As floating wind moves toward arrays, lessons from Renmarinas demos ( anchoring performance, platform stability, environmental data) feed into design of commercial farms. It effectively “buys down” risk for first movers, ensuring that when auctions occur, there is a pipeline of vetted concepts and local know-how.
Ports 4.0 (Puertos del Estado)
Ports 4.0 is an ongoing port innovation fund in Spain (managed by Puertos del Estado) aimed at modernizing port operations and infrastructure. While not exclusive to offshore wind, it has become a vehicle to support logistics and industrialization projects relevant to floating wind. Through competitive calls, Ports 4.0 offers grants and equity for ideas that improve port efficiency or enable new activities. In the context of floating wind, it has funded feasibility studies for offshore wind staging in ports like Las Palmas (Canary Islands) and La Coruña, and prototypes of heavy-lift robotic systems for turbine assembly. By 2025, the program had a dedicated “Blue Economy” category where proposals related to offshore renewable deployment are encouraged. This constant trickle of innovation funding helps Spanish ports adapt – by automating blade handling or developing digital twins for port capacity planning – so they can serve the unique needs of floating wind (large footprints, wet storage of platforms, etc.). The outcome will be more competitive, offshore wind-ready ports able to attract developers for staging and O&M, which is essential as Spain eyes floating projects off Galicia, Catalonia, and the Canaries.
ICO Sustainable Financing Lines
The Instituto de Crédito Oficial (ICO) – Spain’s state finance institution – provides green credit lines and guarantees to support domestic companies in renewable energy and clean-tech supply chains. Through programs like ICO “Sostenibilidad” and “ICO Verde”, it offers long-term loans at favorable rates for projects that advance climate goals. In offshore wind, ICO has co-financed manufacturing upgrades (for example, a Spanish turbine tower factory expansion received low-interest ICO loans) and provided working capital to SMEs supplying offshore projects. Additionally, ICO can issue guarantees for large capital investments. In one notable case, ICO teamed with the European Investment Bank to guarantee a €100m+ financing for Navantia’s offshore wind division (Navantia Seanergies), helping the shipyard fund its production of floating foundations. By mid-2025, ICO had several Green & Sustainable bond issuances, channeling billions into its green lending pool. Spanish firms in the floating wind value chain – from steel fabricators to environmental consultants – benefit from this easier access to credit, which reduces financing costs and encourages expansion to meet future demand.
CESCE Green Export Credit Insurance:
CESCE, Spain’s export credit agency, has introduced green guarantees and insurance products to back Spanish offshore wind exports. For example, CESCE provides bonding and insurance for Spanish manufacturers supplying components to foreign wind farms (much like UKEF for the UK). When Navantia-Windar export floating platform components (as they did for Scotland’s Kincardine project), CESCE can insure the transaction, assuring the overseas buyer of delivery or refund in case of issues. CESCE also offers pre-financing guarantees that allow Spanish exporters to obtain bank loans to fulfill large offshore orders (with CESCE covering the bank’s risk). In 2023, CESCE rolled out a dedicated “Green” classification for projects it supports, aligning with EU sustainable finance criteria – this includes offshore wind projects, meaning exporters in that sector may get higher coverage limits or lower premium costs. By de-risking export deals, CESCE helps Spanish firms compete globally. As floating wind picks up internationally (in Asia and the U.S.), Spanish companies – which are already leaders in fixed-bottom substructures and electrical systems – can leverage CESCE’s backing to secure contracts, thus maintaining a robust domestic industry base between local Spanish projects.
Basque Country Initiatives (EVE & BiMEP)
The Basque Government has been particularly proactive in floating wind. The Ente Vasco de la Energía (EVE) runs regional grant schemes – one notable example is a €2.5 million support line to “impulsar la instalación y prueba de dispositivos de cimentación flotante” (to boost the installation and testing of floating wind foundation devices). This fund has aided the development of prototypes like Nautilus and demo projects at the BiMEP test site. BiMEP (Biscay Marine Energy Platform) itself, co-owned by EVE and IDAE, is an important public infrastructure: a grid-connected offshore test area with four berths and 20 kV export cable, specifically established to host floating platforms and wave energy converters. BiMEP offers reduced-fee access for R&D trials and has attracted projects like DemoSATH (floating turbine) and HarshLab (offshore testing lab). The Basque Country also invests in its maritime industry for wind: the Bilbao port has seen expansion in manufacturing (Haizea Wind’s XXL tower factory) facilitated by regional incentives. Additionally, Basque R&D centers (TECNALIA, NAUTILUS consortium) have received regional funds to innovate in mooring systems and dynamic cables for floating wind. These instruments underscore how regional governments in Spain co-invest alongside Madrid – building local expertise and facilities that ultimately feed into national targets. The Basque example, with EVE’s funding and BiMEP’s world-class test center, serves as a template for other coastal regions ( Canary Islands, Andalusia) to harness their unique advantages (deep ports, academic centers) in support of floating wind deployment.
EIB & CaixaBank Green Trade Finance for Navantia
In October 2025, the European Investment Bank (EIB) and CaixaBank struck a notable deal to bolster Spain’s offshore wind manufacturing. They signed a €50 million counter-guarantee agreement that allows CaixaBank to issue up to €100 million in green guarantees for Navantia Seanergies, the renewables arm of shipbuilder Navantia. This effectively means when Navantia bids or contracts to build offshore wind components (like floating platforms or substations), CaixaBank can provide the required performance bonds and advance payment guarantees to clients, with EIB taking 50% of the risk. The facility improves Navantia’s liquidity and credibility when taking on large international projects. It was part of the EIB’s Wind Power Package to support EU supply chains. Thanks to this, Navantia’s yards in Fene (Galicia) and Puerto Real (Cádiz) can confidently scale production (hiring workers, buying materials) for upcoming floating wind orders, knowing the financing tools are in place. The EIB noted this would help add manufacturing of substations and floating/fixed foundations in Spain’s economy. This innovative blended finance – EU bank plus national bank – exemplifies how Spain taps European funds to reinforce domestic industry. Similar credit enhancements are likely to follow for other key players ( wind turbine OEMs in Spain), ensuring the country’s companies have the financial muscle to participate in the global floating wind market.
Overview
Italy plans large-scale subsidy programmes paired with port investment, export guarantees and national bank co-financing to mobilise industry and finance. The policy package is designed to attract international developers and to seed domestic industrial capacity.
FER‑2: Renewables Auction & CfD scheme
Italy has received EU approval for a massive €35 billion subsidy program running until 2028 to support innovative renewables, notably floating offshore wind. Under the upcoming FER-2 decree, Italy will award two-way Contracts for Difference to offshore wind projects, giving developers long-term price guarantees. This scheme targets 4.6 GW of new capacity across technologies (offshore wind, floating wind, tidal, geothermal, etc.). It will likely take the form of competitive tenders where floating wind developers bid for a strike price contract, similar to the UK model. The European Commission’s approval (June 2024) noted that Italy’s CfD mechanism for floating wind is crucial to meet Green Deal goals while minimizing state aid distortions. Italy is now preparing its first offshore wind tenders, expected in 2025–2026, after finalizing maritime spatial plans and grid connection rules.
Port and Infrastructure Investments:
Recognizing that port infrastructure is vital for floating wind, Italy designated key offshore wind hub ports and allocated public funding to upgrade them. In July 2025, an inter-ministerial decree identified the ports of Taranto and Augusta as national offshore wind hubs, with a planned €78.3 million investment for dredging, quayside reinforcement, and assembly areas. This funding, spread over 2025–2027, is financed by reallocating revenues from CO₂ allowance auctions (EU ETS funds). The aim is to equip these ports in Puglia and Sicily to handle the production and deployment of floating turbine platforms, blades, and anchors. Additional Italian ports (Brindisi, Ravenna, Civitavecchia) are also being evaluated for upgrades as the sector grows. Beyond ports, Italy’s state investment bank (Cassa Depositi e Prestiti) and EU recovery funds are expected to support grid enhancements and onshore infrastructure to integrate offshore wind, although no dedicated floating-wind-specific facility has been announced apart from the port plan.
SACE – Green & “Archimede” Guarantees
SACE, Italy’s export credit and investment guarantee agency, plays a dual role in offshore wind: supporting exports and backing domestic green investments. In 2023, SACE launched the “Archimede” guarantee program, a massive scheme (up to €60 billion exposure by 2029) to underwrite loans to Italian companies in strategic sectors like digital and green transition. Under Archimede, SACE can guarantee (typically 70–80%) of large corporate loans for projects such as offshore wind farm construction, grid upgrades, or factory retooling for turbine components. This effectively lowers borrowing costs and enables banks to lend more freely to the sector. For instance, if an Italian developer or supplier needs a €200 million loan for a floating project, SACE’s guarantee assures the bank of repayment (backed by Italy’s treasury), thus “crowding in” private finance. Archimede is already being utilized – in July 2025, Telecom Italia raised a SACE-backed €750m loan for digital upgrades, and the same mechanism is available for renewable infrastructure. Alongside Archimede, SACE offers Green Guarantees (part of Italy’s Green New Deal program), which have supported renewable energy projects totaling several billion euros since 2020. These guarantees specifically target climate-friendly investments within Italy, including wind farms.
CDP & Invitalia
CDP is Italy’s national investment bank and sovereign fund, and it is at the forefront of financing the clean energy transition. Through CDP Spa and CDP Equity, it provides both loans and equity capital to renewables and infrastructure projects. For floating wind, CDP’s role is multifaceted: it has co-invested in projects (notably via the joint venture GreenIT), and it lends to enable supply chain growth. GreenIT is a JV between CDP Equity and Eni’s Plenitude, which partnered with Copenhagen Infrastructure Partners – together, in 2024 they formed a consortium “Divento” to develop five floating wind farms totaling ~3 GW in Italy. CDP’s equity stake (through CDP Equity) in this pipeline signals government backed commitment, making it easier to attract other investors and obtain project finance. On the lending side, CDP can offer long-term, low-rate loans for grid connections or port improvements that commercial banks might shy from.
Invitalia – Development Contracts (Contratti di Sviluppo)
Invitalia, the national economic development agency, offers powerful incentives for large industrial projects through its “Development Contracts.” These provide a mix of grants, soft loans, and tax credits to companies investing above certain thresholds (usually >€20 million) in sectors deemed strategic, especially in Southern Italy. For the offshore wind supply chain, an investor building a new plant – say a facility to manufacture floating platform components in Naples, or a turbine assembly hall in Sicily – could apply for a Contratto di Sviluppo. If approved (based on job creation, innovation, etc.), Invitalia might cover 30-50% of the investment cost via grants and subsidized financing. In 2022–2025, the government explicitly listed renewable energy equipment manufacturing as eligible under these contracts, with some funded by Italy’s Recovery Plan. For example, an Italian company repurposing a former steelworks in Calabria to produce offshore wind tower sections could secure support. Invitalia also supports “Development Contracts for Energy Transition” targeting green hydrogen, batteries, and possibly floating wind components. A notable recent deal (2023) saw Invitalia approve €50+ million to help reconvert an old industrial site near Naples into a “Green Factory” for wind and solar equipment.
Blended finance (EIB, InvestEU)
Italy is tapping blended finance solutions where national guarantees (SACE) combine with European investment (EIB and InvestEU) to fund offshore wind infrastructure. For example, a template already exists where the EIB provides long-term loans to Italian green projects, which are then partially guaranteed by SACE and sometimes the EU’s InvestEU program. A case relevant to offshore wind is the EIB’s Wind Power Package (a €5 billion EU-wide program): Italy can benefit by applying for low-cost EIB loans for its floating projects. These loans might cover, say, 50% of a wind farm’s cost at attractive interest rates (thanks to EIB’s AAA rating), if paired with either an InvestEU guarantee or SACE Archimede guarantee to secure repayment. Italy has also worked with the European Investment Fund (EIF) to support SMEs in the wind supply chain – an InvestEU agreement in 2025 unlocked €6.5 billion in lending for Italian companies’ innovation and sustainability investments. This means smaller supply chain firms (like those providing sensors, services, secondary components for floating turbines) can get bank loans under favorable terms, guaranteed by EIF, to expand capacity.
Private Sector & Joint Ventures
While Italy is early in offshore wind development, private funding is ramping up via partnerships. GreenIT, a joint venture of Eni, CDP Equity, and Copenhagen Infrastructure Partners, has plans for several floating wind farms totaling over 5 GW. Major developers (Equinor, Renexia, Saipem) have announced investments in Italian floating projects – indicating that much of the project financing will come from corporate sources once auctions begin. In the interim, companies are funding feasibility studies and environmental surveys. For example, Italy’s first (and so far only) operative offshore wind farm – the small 30 MW fixed-bottom array off Taranto – was financed by Renexia with support from Italian banks, paving the way for confidence in offshore projects. Going forward, the combination of the CfD subsidy, port upgrades, and strong interest from international wind developers creates a conducive environment for private capital to flow into Italian floating wind farms.
Overview
Greece is focusing on auctioned sliding Feed‑in Premiums (FiP), strengthened planning & permitting frameworks, recovery‑plan funding for enabling infrastructure and development‑bank guarantees to improve bankability.
Sliding Feed‑in Premium tenders
Greece enacted its Offshore Wind Law in 2022, laying the groundwork for competitive tenders to install at least 2 GW of offshore wind by 2030. Given the deep Aegean waters, this will predominantly be floating offshore wind. The support mechanism chosen is a sliding Feed-in-Premium (FiP) – essentially a Contract for Difference where the government tops up market revenues to a fixed strike price and claws back excess when prices are high. The regulatory authority RAE will run auctions zone-by-zone once marine spatial planning is finalized (six priority areas have been identified around Crete, Cyclades, etc.). The first auction is anticipated around 2025–2026, with awards by 2027, to keep Greece on track for first projects before 2030. Winners will receive long-term operational aid (20-year FiP contracts) ensuring bankable revenue for their floating projects. This auction scheme is the main funding instrument for Greek offshore wind – it introduces private capital via investor bids, backed by state-guaranteed premiums funded through the RES levy.
Law 4964/2022 (HEREMA) and permitting
Greece’s first Offshore Wind law (July 2022) set up the institutional and licensing framework to enable investments. It appointed HEREMA (Hellenic Hydrocarbons and Energy Resources Management) – formerly HHRM – as the lead authority for offshore wind development. HEREMA will identify Organised Development Areas (ODAs) in Greek waters suitable for wind farms, conduct preliminary studies, and then tender those areas. Crucially, the law streamlines permitting: instead of developers assembling sites piecemeal, the state will do spatial planning and strategic environmental assessments upfront. Six broad priority zones (around Crete, Dodecanese, Thrace etc.) are being assessed for wind farm development. Law 4964 also introduced a one-stop licensing process with defined timelines – aiming to avoid multi-year delays. It set an aspiration that the first projects should be operating by 2030, hence it compresses steps like marine lease, grid connection, and environmental permit into a coordinated sequence. The law additionally provided that transmission operator ADMIE is responsible for building any needed offshore/onshore grid links for the wind farms, ensuring grid connection costs will be socialised or at least centrally managed.
Greece 2.0 – Recovery & Resilience Plan (RRF) (Hellenic Development Bank)
Greece’s EU-funded recovery plan (Greece 2.0) includes reforms and investments laying groundwork for offshore wind. Notably, it earmarked funds for mapping offshore wind potential, environmental studies, and grid upgrades to integrate future turbines. For example, RRF money was allocated to digitalize hydrographic and wind resource data for Greek seas, which HEREMA uses to delineate wind farm zones. It also finances capacity-building: Greek ministries have hired technical advisors (via RRF grants) to design the auction system and draft tender documents in line with EU best practices. On the investment side, the RRP provided capital to ADMIE for certain grid reinforcement projects (new substations, higher-capacity undersea cables between islands and mainland) explicitly needed to handle offshore wind feed-in by 2030. Essentially, RRF funding is front-loading the enabling infrastructure so that when private investors build the wind farms, the grid can take the power.
Hellenic Development Bank (HDB) – Green co-financing
The Hellenic Development Bank, relaunched in 2019, provides loans and guarantees to co-finance private investments aligned with development goals (SME growth, innovation, decarbonization). HDB has introduced dedicated green financing programs – for example, in 2022 it launched a €500m “Growth and Green Economy Fund” in partnership with commercial banks. Through such programs, HDB can offer subordinated loans or guarantee a portion of commercial loans for renewable projects, effectively improving the financing terms. For the offshore wind supply chain, HDB could, for instance, guarantee 50% of a loan a Greek SME takes to buy new equipment for making turbine parts, giving the lending bank confidence to extend credit. HDB also runs co-financing facilities where it lends side-by-side with banks at low interest for a portion of the amount. In a hypothetical case: a Greek shipyard needs €30m to adapt for floating platform construction – HDB might provide €10m at near-zero interest, while a partner bank provides €20m at market rate, lowering the average cost of capital. The Development Bank is also involved in EU-backed initiatives; it channels some InvestEU funds to Greek enterprises. By 2025, HDB had expanded guarantee schemes that could be used by supply chain entities (like cable installers or support vessel operators) to get loans for scaling up. It’s worth noting HDB’s ancestor (ETEAN) had helped renewable energy cooperatives with loan guarantees, so there’s precedent. With offshore wind being new and potentially high-risk for Greek lenders, HDB’s role to “de-risk” domestic financing is vital. Essentially, HDB acts as an intermediary that blends public funds with private bank capital to ensure Greek businesses can participate in the offshore wind boom – whether by building parts, developing projects, or servicing operations.
EIB – Green credit lines for Greece (SMEs & Mid-Caps)
The EIB has a long history of funding energy infrastructure in Greece, and in recent years it has set up green credit lines with Greek banks specifically for climate-related investments. For example, the EIB and Greek commercial banks have signed facilities where EIB provides hundreds of millions of euros to the banks, on the condition they on-lend to renewable energy and energy efficiency projects (often targeting SMEs and mid-caps). One such credit line (2021) was €400m for green investments, which by 2023 had financed several small onshore wind and solar farms. The same mechanism can finance local suppliers or ancillary infrastructure for offshore wind: a small Greek engineering firm that needs €5m to build a manufacturing hall for turbine components can borrow from a bank under these favorable EIB-funded terms (longer tenor, lower interest). The EIB also directly finances larger projects – notably it has funded Greek grid upgrades and interconnectors ( the Cyclades HV interconnection) which indirectly facilitate offshore wind integration. Going forward, the EIB could directly finance a portion of an offshore wind farm’s capex (it has done so for fixed offshore wind in other countries). For instance, if a 250 MW floating project in Greece costs €800m, the EIB might provide a €150m senior loan with a 20-year term.
Overview
Portugal combines planned auctions, maritime spatial planning (PAER), cluster strategies, EU structural funds and InvestEU‑backed guarantees to create a trajectory for floating wind deployment and supply‑chain growth.
Offshore Wind Auction Program
Portugal has committed to an ambitious floating wind rollout, targeting 2 GW by 2030 as a first phase and envisioning up to 10 GW in later years. The government in January 2025 approved four ocean areas for offshore wind development and is finalizing the auction design, aiming to hold its first competitive auction in 2025. This will allocate seabed leases and long-term energy contracts to developers – likely a CfD or fixed-price power purchase agreement – for floating projects off northern and central Portugal (e.g. near Viana do Castelo, Leixões, Figueira da Foz, and Sines). The auction is expected to feature a pay-as-bid pricing for a defined capacity quota, ensuring winning bidders have a stable tariff. This approach follows successful models in the UK and France, and the government explicitly wants to “create scale, synergies and predictability” with a pipeline of projects. The auctions will be the main funding mechanism, leveraging Portugal’s strong investor interest (several major consortia – Ocean Winds/EDP, IberBlue, CIP, TotalEnergies/Galp – have already expressed interest in the upcoming tender.
Cluster and Supply Chain Initiatives
Portugal is pursuing a cluster approach, aiming to become an Atlantic hub for floating wind. The government’s plan emphasizes attracting manufacturers and assembly facilities to Portugal’s shores. Though not a direct funding scheme, this strategy involves incentives such as favorable industrial policy, streamlined licensing, and possibly tax breaks for offshore wind supply chain companies. In early 2025, Portugal’s Secretary of State for the Sea highlighted the country’s “strategic offshore renewable cluster” initiative, which coordinates ministries to facilitate private investment in floating wind manufacturing. Additionally, the Crown Estate-style model is under discussion – where Portugal could award seabed rights with conditions on local content or fees that feed back into infrastructure funding. In summary, Portugal’s support for floating wind is currently centered on the upcoming power auctions (to secure revenue for projects) and EU-supported financing for enabling infrastructure, complemented by policy-driven efforts to lure private sector investment into its floating wind supply chain
PAER – Offshore Renewable Allocation Plan
Portugal’s Plano de Afetação de Espaço Marítimo para Energias Renováveis (approved by RCM 19/2025) is essentially the maritime spatial plan cum roadmap for offshore wind. This approved four zones for development, totaling ~2 GW by 2030, and outlines the process for auctions and licensing. By legally designating these areas, PAER gives developers certainty on where they can build (and communities clarity on where wind farms will go). This reduces project development costs – avoiding speculative leasing or legal challenges. The plan underwent strategic environmental assessment, and it commits to environmental monitoring and mitigation (to be funded by project developers but coordinated by the state). The PAER effectively pre-approves the concept of wind farms in those zones, which expedites environmental licensing later. It also stipulates grid connection points on land for each zone (e.g. linking Viana do Castelo zone to the Pedrogao substation) and plans necessary onshore grid reinforcements. In funding terms, the PAER is a government in-kind contribution: by doing centralized planning, Portugal lowers the burden on each project (which in other countries might have to fund all these studies and grid upgrades alone). Moreover, PAER is forward-looking – it mentions that beyond the initial 2 GW, additional zones seaward of those or entirely new ones (e.g. south of Algarve) can be considered, up to 10 GW potentially. This signals to manufacturers that Portugal is serious about scaling up – so investing in a factory has long-term market. The PAER and subsequent decrees (like Order 4752/2025) also set a timeline: within 60 days, rules will be published; within 180 days, auction launched. This creates a schedule that financial backers can monitor – a signpost that, for example, by Q4 2025 projects will be awarded, by 2026 they’ll sign contracts, etc., which helps banks and funds allocate capital in advance. In summary, PAER is a planning instrument that underpins funding: it derisks and accelerates the environmental and spatial aspects, making the 2 GW target feasible and attractive to financiers who often worry about permitting risk.
Portugal 2030 – EU Structural Funds for Blue Economy
Under the Portugal 2030 EU multiannual framework, the country has access to significant cohesion funds (ERDF, Cohesion Fund, Just Transition Fund, EMFAF) some of which are directed at the blue economy and energy transition. For example, the MAR 2030 program (funded by EMFAF – European Maritime, Fisheries and Aquaculture Fund) dedicates money to diversify coastal economies and modernize ports with an eye on renewables. Around €116 million was set aside to support “blue economy innovation,” which includes offshore renewables and related training. This can fund things like: new training programs for offshore wind technicians at coastal polytechnic institutes, or an innovation center for floating wind in partnership with universities (providing lab facilities and incubation for start-ups). ERDF funds in regions like Norte and Centro can co-fund port improvements (e.g. the expansion of quay at Leixões port to handle large turbine components was partly eligible for ERDF under a competitiveness program). The Just Transition Fund in Portugal, while focused on coal regions, might indirectly help offshore wind by supporting reskilling of workers (some coal plant workers in Sines could be retrained for offshore wind construction, for instance). Additionally, Compete 2030 (the national operational program for competitiveness) offers grants to manufacturing SMEs for capacity expansion – a wind component supplier can get 30% of new equipment cost reimbursed if it improves energy efficiency or innovation, which many such projects qualify for. In effect, Portugal is knitting offshore wind into various EU-funded programs – none huge on their own for offshore wind, but collectively impactful. They reduce the local cost base: a port that gets 50% funding from Europe to build a heavy-lift pier can charge wind projects less in port fees; a blade factory that got an ERDF grant can afford to sell at slightly lower cost and still profit. These structural funds also ensure that benefits of offshore wind development (jobs, innovation) are spread: e.g., funding an offshore wind training simulator at a vocational school in Setúbal with EU money means local people can acquire skills for the industry without the wind farm developer footing that bill. All of this complements the auction scheme by enhancing Portugal’s attractiveness as a place to invest. For every euro the state or EU invests in enabling actions, the expectation is many euros of private investment flow into the actual projects and supply chain.
Connecting Europe Facility (CEF) & Cross-Border Renewables
Portugal is eyeing EU support for integrating its offshore wind not just locally but with the broader European grid. Under the CEF Energy programme, Portugal can access funding for studies or even infrastructure that have cross-border impact. For instance, a stronger interconnection with Spain will be needed as renewables rise – Portugal and Spain have applied for CEF grants to increase interconnector capacity, which will allow offshore wind power to be exported/imported efficiently and reduce curtailment. Also, the CB RES facility (within CEF) is designed to fund innovative joint renewable projects between countries. Portugal could, for example, partner with Spain (or even Morocco, via Spain) on a virtual cross-border offshore wind farm where Spanish consumers or the government pay into the project in exchange for some of the produced green energy. If structured as a CB RES project, it could get EU grant support. There’s also a concept of a “Trans-European Offshore Grid” in the Atlantic – if Portugal’s floating wind expands toward 10 GW, some of that could one day connect into a meshed offshore grid linking to Spain and France. Feasibility and design studies for that concept could attract CEF funding. In 2023, the European Commission noted Portugal’s potential to contribute to cross-border renewable goals (given its coastline and wind resource) in context of the CB RES mechanism. By engaging early, Portugal can secure a slice of those EU funds. In practical terms, what this means for funding is that some upfront costs (maybe €10–20 million for joint planning studies, or an initial €50 million toward an interconnector upgrade) might be covered by EU grants, rather than baked into project bids or network tariffs. That lowers overall system cost, benefiting both developers and consumers. It also increases the market size for Portuguese offshore wind – if Spain or others are chipping in to use the power, that could justify larger projects and more investment. Essentially, CEF support is helping ensure Portugal’s floating wind is not an energy island but part of a connected European market, which improves its economics and resilience (a selling point when attracting project finance).
InvestEU Guarantees via Banco Português de Fomento (BPF)
Portugal’s national promotional bank, BPF, in cooperation with the European Investment Fund (EIF), launched a €6.5 billion guarantee programme in 2025 to spur lending for innovation and sustainability. This program (under InvestEU) provides portfolio guarantees to Portuguese commercial banks, encouraging them to issue loans to companies in green sectors by protecting a portion of the loan against default. For the offshore wind sector, this is a boon for supply chain companies and ancillary service providers. For example, a Portuguese metalworks firm in Setúbal that needs a €5 million loan to upgrade its facilities to produce floating platform components can get that loan with an EIF/BPF guarantee – the bank knows if the firm defaults, the guarantee will cover, say, 70% of losses. Thus the bank can offer a lower interest rate and require less collateral. The InvestEU-backed guarantee essentially uses EU and Portuguese funds to leverage private lending at scale (up to 40,000 companies across sectors). In context, dozens of SMEs feeding into offshore wind – from diving services to composite manufacturers – can finance expansion under this scheme. BPF also provides co-investments and mezzanine financing to innovative firms; an offshore wind tech startup developing a new floater design could receive a quasi-equity investment through BPF’s innovation fund, backed by InvestEU. This fills a gap in Portugal’s financial market by providing risk-tolerant capital. Additionally, BPF signed an InvestEU guarantee agreement (210 million) directly aimed at climate and infrastructure, which can be used to back large loans (e.g. a loan for a blade factory). In essence, these guarantees reduce the risk for local banks to engage with the emerging offshore wind sector. That increases liquidity and lowers financing costs for Portuguese companies, making them more competitive. By 2025, over 900 companies had already benefited from BPF InvestEU guarantee lines in various green projects. As floating wind ramps up, this facility stands ready to support both the big-ticket items (with BPF possibly co-funding a portion of a wind farm debt or a port investment) and the smaller supply chain needs (through partner banks lending to SMEs). It’s a way of ensuring that the availability of funding is not a bottleneck for Portuguese firms to participate in floating wind – aligning with the country’s aim to maximize local economic returns.
European Investment Bank (EIB) – Pioneering Project Finance
The EIB has already signaled confidence in Portuguese floating wind by financing the WindFloat Atlantic pilot – it provided a €60 million loan under the InnovFin Energy Demo Project instrument (with EU support) to that 25 MW project, one of the first floating farms. That loan (signed 2018) was pivotal in proving floating wind’s bankability. Going forward, the EIB is expected to continue as a key financier for Portugal’s commercial-scale projects. Under InvestEU’s infrastructure window, EIB could lend around 20–30% of a project’s cost at attractive rates. For instance, for a 500 MW floating farm off Figueira da Foz (capex ~$1.5 billion), EIB might contribute $300–$450 million in senior debt. The presence of EIB typically lengthens loan tenors (which is helpful given floating wind’s high upfront cost but long life) – EIB can offer 15-20 year terms, reducing annual debt service. Moreover, EIB often offers technical advice during due diligence, raising overall investor confidence. In Portugal, EIB might also finance supportive infrastructure: grid reinforcements to connect offshore wind, or port upgrades if deemed part of the project. For example, if the Sines port expansion for floating wind is structured as a PPP, the EIB could lend to the port authority. EIB financing is usually contingent on high environmental and social standards, which aligns well with offshore projects that must be carefully managed for fisheries and ecosystems – essentially, if EIB is on board, it signals the project meets robust ESG criteria. Finally, the EIB can facilitate blended finance by bringing in other institutional lenders (like European commercial banks or other national promotional banks) through syndication. In Portugal’s relatively small financial market, having EIB partake means local banks can lend alongside with more confidence (and possibly with EIB guaranteeing part of their exposure through structures like Project Bond Credit Enhancement, which EIB has used in some EU projects). In summary, EIB’s continued involvement will lower the cost of capital for Portuguese floating wind and was crucial in the first pilot – showing it will “walk the talk” on innovative tech. The successful performance of WindFloat Atlantic with EIB support now sets the stage for EIB to scale up support on the forthcoming 2 GW auction projects, bridging the gap until purely private project finance can take over as the sector matures.
Fundo Azul & Fundo Ambiental (National Blue and Green Funds)
Portugal has two notable public funds that, while modest in size, support the ecosystem around offshore wind. The Blue Fund (Fundo Azul), managed by the Ministry of the Sea, finances projects that develop the blue economy, innovation, and scientific knowledge of the ocean. It runs calls for proposals annually. In recent years, Fundo Azul awarded grants to several offshore renewable-related initiatives: for example, a project to design eco-friendly artificial reefs for wind farms, a training program for offshore wind O&M technicians in collaboration with a polytechnic, and a pilot deployment of a wave energy device that shares export cable with a floating wind turbine. Typical grant sizes are €100k–€500k, which can make a difference for startups or research teams. In 2022, Fundo Azul (with PRR linkage) co-funded a feasibility study on using Portuguese naval yards for floating platform assembly. Such grants de-risk R&D and environmental integration, improving the long-term sustainability and public acceptance of offshore wind. The Environmental Fund (Fundo Ambiental) is a broader instrument that supports climate and environmental policy objectives. It has funded renewable energy pilot projects (like solar and storage for islands) and could be tapped to support offshore wind-related environmental monitoring or community benefit schemes. For instance, Fundo Ambiental could finance part of the cost of installing bird and bat monitoring radar on floating turbines, or sponsor fisheries compensation schemes around wind farm areas – expenditures that, if left to the developer, would increase project costs. By covering these, the fund indirectly lowers project expenses. Additionally, the Environmental Fund can provide electric mobility grants which, tangentially, create more demand for green electricity including wind. Both funds also sometimes serve as blending agents – using them to co-finance alongside EU funds. For example, a joint Blue Fund and EMFF project in 2020 advanced a study on multi-use platforms (wind and aquaculture). Overall, while not huge, these funds fill niches: they ensure that the “soft” aspects (research, environmental protection, skills, stakeholder engagement) of floating wind development are attended to with public support, making the hard investment (the wind farms themselves) smoother and more accepted. This comprehensive approach helps avoid delays and opposition, which in turn is crucial for keeping financing on track and costs down. The presence of these funds shows the government’s commitment to maximize positive impacts (and minimize negatives) of offshore wind, which is important for sustaining political and social backing – an often underrated but critical factor in securing long-term funding and investment.
