Part ofEnergy

Updated June 2026 · England & Wales
Bringing two or more organisations together to build a wind farm, solar park, battery storage site or hydrogen facility is rarely straightforward. The capital requirements are substantial, the regulatory landscape keeps shifting, and each partner usually brings something different to the table, whether that is land, finance, technical know-how or grid connection rights. A joint venture agreement is the contract that holds all of this together. It sets out who does what, who pays for what, who owns the output, and what happens when things go wrong. This guide walks through how these agreements are typically structured for energy projects in the UK, the commercial and legal issues that tend to surface during negotiation, and the practical questions you should be asking before you sign. It is written for founders, project developers and in-house teams who are weighing up a collaboration rather than going it alone.

What this document is

A joint venture agreement, often shortened to JVA, is the document that governs a commercial collaboration between two or more parties working together on a defined project or business activity. In the energy sector, the project is usually the development, construction, operation or financing of a generation asset, storage system or related infrastructure.

The agreement itself can take different legal forms. Some joint ventures are purely contractual, meaning the parties work alongside each other but never form a shared company. Others involve incorporating a special purpose vehicle, commonly an SPV set up as a private limited company or a limited liability partnership, which becomes the legal entity that owns the project and enters into contracts with suppliers, lenders and offtakers.

The choice of structure has tax, liability and accounting consequences, and it also affects how easily a party can exit if the relationship breaks down. A well drafted JVA will reflect the commercial deal the parties have agreed and anticipate the issues most likely to arise over the life of the project.

How to use this document

  1. Agree the commercial fundamentals before drafting. Work out what each party is actually bringing to the deal, how costs and revenues will be split, how long the venture is expected to last, and what success looks like for each side. Getting this clear on paper, even as a short heads of terms, avoids months of wasted legal time and exposes misalignment early.
  2. Choose the right legal structure. Decide whether the venture will operate through a contractual arrangement, a limited company, a limited liability partnership, or another vehicle. Each option has different implications for tax, limited liability, disclosure obligations at Companies House, and how profits flow back to the participants. The right choice depends on the project's scale, funding profile and exit strategy.
  3. Define contributions, governance and decision making. Spell out exactly what each party must contribute, whether that is cash, land, intellectual property, permits or personnel. Set out how the board or management committee is composed, which decisions require unanimous consent, and how deadlocks between equal partners will be resolved. Reserved matters lists are particularly important in 50/50 ventures.
  4. Address funding, distributions and future capital calls. Renewable projects often need further injections of capital as they move through development, construction and operation. The JVA should say how those calls are made, what happens if a partner cannot or will not contribute, and how dilution or default provisions operate. Waterfall provisions governing how revenue is distributed also need careful attention.
  5. Plan for exit, dispute resolution and termination. Build in clear mechanisms for transferring interests, including pre-emption rights, drag and tag along provisions, and procedures for valuing a departing partner's stake. Specify the governing law, usually the law of England and Wales, and choose a dispute resolution route such as arbitration or the courts. Think about what triggers termination and what happens to the project assets if the venture ends.

Common questions

Q Do we need a separate company to run a renewable energy joint venture?
Not always. Some smaller or shorter term collaborations work well as purely contractual arrangements, where each party keeps its own separate identity. For larger projects that need external debt financing, a special purpose vehicle is usually preferred because lenders want a clean, ring fenced entity to lend against. The right answer depends on scale, risk appetite and how the project will be funded.
Q How are profits and losses typically shared in an energy JV?
Profit sharing usually reflects each party's contribution, but it does not have to be a straight split in proportion to equity. Many agreements use a waterfall that pays back development costs first, then delivers a preferred return to certain investors, before sharing residual profits. Losses can be handled similarly. The key is making sure the mechanics are set out clearly and tested against realistic financial models.
Q What happens if one party wants to exit the venture early?
A well drafted JVA will include exit provisions. These often include pre-emption rights, giving the remaining partners first refusal on any transfer, and tag or drag along rights that protect minority or majority positions when a third party buyer appears. There may also be a valuation mechanism, often by an independent expert, to price the exiting party's interest fairly.
Q How are deadlocks resolved between two equal partners?
Fifty fifty ventures carry a real risk of paralysis if the partners disagree on a reserved matter. Common solutions include escalation to senior executives, expert determination, mediation, and, as a last resort, mechanisms such as a Russian roulette or Texas shoot out clause that force one party to buy out the other. The right mechanism depends on the commercial relationship and how critical decisions are to the project.
Q What regulatory issues typically affect UK energy JVs?
Energy joint ventures often touch on planning consent, grid connection agreements, environmental permits, and sector specific regimes administered by Ofgem. Depending on the transaction size, merger control rules may apply, and the National Security and Investment Act can also be relevant for certain energy assets. These issues should be identified early because they can affect structure, timing and deal conditions.
Q Should a JVA cover intellectual property and technology?
Yes, particularly where one partner is contributing proprietary technology such as turbine designs, software, battery chemistry or control systems. The agreement should make clear what IP is being licensed to the venture, what is being assigned outright, and who owns any improvements or new IP created during the project. Getting this wrong can create expensive disputes later.
Q Can a JVA be changed after it has been signed?
It can, but only if all the parties agree, unless the agreement itself specifies a different process for variations. Most well drafted JVAs require written amendments signed by authorised representatives of each party. Informal side arrangements or verbal understandings are best avoided because they create uncertainty and may not be enforceable.
