The scale of investment required for Europe’s renewable energy transition — the EU’s REPowerEU plan targets 600 GW of solar and wind capacity by 2030 — has made the joint venture the default structure for large energy projects. No single participant typically has the development expertise, balance sheet, regulatory relationships, and off-take capabilities to execute projects of the required scale alone. Developers, utilities, infrastructure funds, sovereign wealth funds, industrial corporations, and grid operators are combining in structures that are commercially complex and legally demanding. Understanding the legal architecture of renewable energy joint ventures is essential for any organisation participating in or financing the energy transition.
Why Joint Ventures Rather Than Other Structures?
The prevalence of joint ventures in renewable energy reflects several structural features of the sector. Large offshore wind projects — the most capital-intensive category — require investment of EUR 1-3 billion per GW of capacity, making project diversification through portfolio approaches essential for most investors. A joint venture between an experienced offshore developer and an infrastructure fund allows the developer to recycle capital across multiple projects while the fund provides long-duration infrastructure investment capital. Utilities enter joint ventures with industrial companies to secure off-take commitments that underpin project economics and satisfy lender requirements for contracted revenue.
Regulatory requirements in some jurisdictions explicitly encourage or require local participation. Several member states — including France, Spain, and the Nordic countries — have designed tender processes for offshore wind licences that favour or require local or national participation, which drives developers to form local joint ventures with national energy companies. Grid connection arrangements in some countries require the generator to partner with the national transmission system operator or distribution network operator, creating further structural drivers for partnership.
Project Company Structures: SPV Architecture
Large renewable energy joint ventures are almost invariably structured through a project company — typically an SPV — that holds the project assets, the grid connection agreement, the relevant permits and licences, and the power purchase agreement. The SPV structure achieves several objectives simultaneously: it ring-fences the project’s assets and liabilities from the parents’ balance sheets; it provides a clean vehicle for project finance lenders to take security over project assets; it enables the joint venture partners to hold different economic interests through their respective shareholdings in the SPV; and it simplifies the exit process, since selling a partner’s interest is a share transaction in the SPV rather than an asset transfer requiring individual assignment of each permit, contract, and licence.
Above the SPV level, the joint venture structure often includes a holding company — particularly in offshore wind where multiple related projects may be developed in a coordinated programme — and may include intermediate holding vehicles in tax-efficient jurisdictions for the investors’ interests. Luxembourg and the Netherlands remain the preferred jurisdictions for the holding layer in European energy joint ventures, for the reasons discussed in the earlier post on European holding companies.
The Shareholders’ Agreement: Key Commercial Terms
The shareholders’ agreement for a renewable energy joint venture addresses the full range of commercial arrangements between the partners and typically runs to considerable length. The most commercially significant provisions are those relating to governance, funding obligations, exit rights, and the allocation of risk and return.
Governance provisions in energy joint ventures must balance the operational requirements of project development and operation — where decisions need to be made quickly and by those with technical expertise — against the investment oversight requirements of passive financial investors who want veto rights over material decisions without being involved in day-to-day management. The typical approach distinguishes between decisions reserved to the board (requiring shareholder approval at the JV level), decisions delegated to the management team or operating partner, and decisions requiring unanimous shareholder consent. Deadlock provisions — specifying what happens if the partners cannot agree on a reserved matter — are critically important in equal joint ventures where neither partner has a casting vote.
Funding obligations determine how the JV is capitalised and what happens if a partner cannot or does not contribute its share of required capital. Renewable energy projects have heavy upfront capital requirements during the development and construction phases, and lenders providing project finance typically require that equity is committed and available before debt is drawn. Dilution provisions — specifying that a partner who fails to fund dilutes their interest in favour of the funding partner — are standard, but the dilution mechanics must be carefully designed to avoid creating a situation where a partner facing temporary capital constraints is disproportionately penalised.
Power Purchase Agreements and Revenue Structuring
The revenue side of a renewable energy JV is typically structured through one or more power purchase agreements (PPAs) or through participation in a government support scheme such as a Contracts for Difference (CfD) or feed-in tariff. The legal structure of the revenue arrangements critically affects the project’s bankability — lenders require contracted, predictable revenue to service project finance debt — and the economic allocation between the JV partners.
Corporate PPAs — long-term bilateral agreements between the project and an industrial or commercial off-taker purchasing renewable electricity directly — have grown rapidly in Europe, driven by corporate sustainability commitments and the relative attractiveness of fixed-price long-term power contracts compared to merchant market exposure. The legal structure of a corporate PPA involves an agreement between the JV SPV and the off-taker, typically on a fixed or indexed price for a ten to twenty-year term. Key legal provisions include the pass-through of balancing and imbalance costs, curtailment risk allocation, force majeure treatment for grid outages, and the interaction between the PPA and any government support scheme that the project also participates in.
Government support schemes introduce public law and regulatory dimensions to the JV structure. CfD payments in the UK and equivalent mechanisms in other member states are contractual arrangements with a government counterparty. The assignment of CfD rights to project finance lenders, the interaction between CfD payment mechanics and the project’s revenue waterfall, and the regulatory conditions attached to CfD eligibility — including requirements about project ownership structure and commissioning timetables — all require specific legal analysis in each jurisdiction.
Exit Provisions and Transfer Restrictions
Exit provisions in renewable energy JV shareholders’ agreements must address the different liquidity needs of different investor types. A developer partner may want to monetise a development interest and recycle capital into new projects within three to five years of commercial operation. An infrastructure fund will typically target a ten to fifteen-year hold period matching its fund duration. An industrial off-taker that entered the JV to secure renewable supply may have an indefinite investment horizon.
Standard transfer restriction provisions — pre-emption rights, drag-along, tag-along, and lock-up periods — apply in energy JVs as in any other commercial JV. Energy-specific provisions include restrictions on transfers to competitors of the off-taker partner, requirements that a transferee satisfy lender creditworthiness requirements (because project finance security packages typically include restrictions on changes of control at the project company level), and in some cases regulatory requirements that limit who may hold interests in licensed energy assets.
Change of control provisions in the project’s key contracts — the grid connection agreement, the CfD contract, and any land lease or easement agreement — require careful management in any transfer. Lender consent requirements under project finance documentation are also triggered by ownership transfers at project company level. A JV partner planning an exit must sequence the consent processes under multiple contracts and regulatory filings, which in practice means that exit timelines in energy JVs are longer than in other sectors and require careful advance planning.
State Aid and EU Regulatory Framework
European renewable energy projects are heavily shaped by EU state aid rules, which govern when and how member state governments can provide financial support for energy projects without distorting competition. The EU’s revised Guidelines on State Aid for Climate, Environmental Protection and Energy (CEEAG), adopted in 2022, provide the framework for assessing whether support schemes — including CfDs, capacity mechanisms, and green hydrogen support — are compatible with the EU internal market.
For JV participants, state aid compliance matters because it affects the design of support schemes, the competitive process (most significant support schemes require competitive tendering to demonstrate aid minimisation), and the conditions attached to aid — including requirements around project timelines, technology specifications, and in some cases ownership or local content requirements. JV partners should also be aware of state aid rules when considering whether co-investment by a public entity in the JV — such as a state-owned utility or a public infrastructure fund — might itself constitute state aid that requires notification and clearance.
Conclusion
Renewable energy joint ventures sit at the intersection of energy sector expertise, infrastructure finance, and cross-border M&A legal practice. Their legal architecture — SPV project company, holding structure, shareholders’ agreement, revenue arrangements, and lender security package — reflects the specific commercial and regulatory requirements of long-duration, capital-intensive infrastructure assets. Partners entering European renewable energy JVs benefit from engaging counsel with both transactional M&A experience and genuine sector knowledge of energy regulation, grid connection law, government support schemes, and construction contracting. The quality of the legal structure established at inception will shape the JV’s operational and commercial performance for decades.
