Private Wire Ppa Template for England and Wales

A Private Wire Power Purchase Agreement (PPA) is a contract that lets an electricity generator supply power directly to a consumer through dedicated private infrastructure, bypassing the public electricity grid. Under England and Wales law, these arrangements must comply with specific regulatory frameworks while offering commercial benefits for both the generator and the off-taker. A private wire route is common where a solar, wind, or combined-heat-and-power project sits on or beside the site that consumes the electricity.

When do you need this document?

You need a Private Wire PPA when establishing direct electricity supply relationships that use private infrastructure. This includes situations where renewable generators want to supply commercial or industrial facilities on the same site or nearby through private cables. Manufacturing facilities seeking guaranteed power from dedicated solar or other renewable sources typically require these agreements, as do business parks developing integrated energy solutions. Private wire arrangements are also used for large-scale developments where multiple buildings share a central generation facility, or when an organisation wants to meet sustainability targets through direct renewable procurement that matches on-site generation to its own demand.

How does a private wire PPA differ from a grid-connected PPA?

Because the parties take on the cost and responsibility of the private wire itself, the contract has to allocate that infrastructure investment clearly.

Key legal considerations

Several provisions must be addressed to ensure compliance and protect both parties' interests. Supply obligations should define the generator's commitment to deliver electricity and the off-taker's obligation to purchase, including force majeure events and supply interruptions. Pricing mechanisms need detailed specification, covering energy charges and any capacity payments, plus adjustment procedures for inflation or regulatory changes. Metering arrangements require precise definition of responsibilities for installation, maintenance, and data collection, as these directly affect billing accuracy. Connection infrastructure provisions must address ownership, maintenance, and upgrade responsibilities for the private wire network. Termination clauses should specify notice periods, asset transfer arrangements, and any stranded-cost recovery. Where the generator relies on external finance, the agreement's term and pricing floor often underpin the financial model the project is built on.

What should the pricing mechanism cover?

Pricing is the clause that decides whether the project works commercially for both sides. A worked example: a 2 MW rooftop solar array supplies a factory next door under a 15-year private wire PPA at a fixed 9 p/kWh, indexed annually to CPI, with a floor of 8 p/kWh and a ceiling of 12 p/kWh. Any generation the factory cannot absorb is exported to the grid and sold separately, with that revenue shared under an agreed split. For the consumer, the benefit is a predictable, often below-retail price for the share of demand met on site; for the generator, the long contract and price floor give the revenue certainty needed to secure investment. Spell out how output is measured, how shortfalls are treated, and how prices move over the life of the contract.

Who typically signs a private wire PPA?

The two core parties are the generator (which builds and operates the plant) and the off-taker or consumer (which buys the electricity). Depending on the structure, a project developer, an asset owner, a funder, and a facilities operator may also be involved, and the drafting should make clear which party holds which obligation. If you also supply power or services to the off-taker under separate arrangements, a service agreement can sit alongside the PPA to cover operation and maintenance scope.

Legal requirements in England and Wales

Your Private Wire PPA must comply with the Electricity Act 1989, which provides the core regulatory framework for electricity supply in England and Wales. The agreement should ensure compliance with the Electricity (Class Exemptions from the Requirement for a Licence) Order 2001, which defines the exemptions allowing private wire operations without a full electricity supply licence. Under the Energy Act 2013, consider the implications for renewable support schemes, particularly where the generator receives Contracts for Difference (CfD) payments or other government incentives, as policy support can affect the economics the contract relies on. The Climate Change Act 2008 may impose carbon reporting and renewable energy obligations that feed into contract terms. Distribution Connection and Use of System Agreement (DCUSA) requirements may apply if the private wire network connects to the public distribution system at any point. You must also comply with health and safety regulations governing private electricity networks and obtain any necessary local authority permissions for infrastructure installation. GenieAI can review the drafted agreement against your position before you sign.

Keeping the agreement current

Energy policy moves quickly, so a private wire PPA signed today should anticipate change over a 10 to 20 year term. A contract drafted in 2026 needs to account for how regulatory shifts, network charging reviews, and support-scheme news flow into pricing and reporting over time. Build in adjustment and review mechanisms rather than fixing terms to the rules that happen to apply on the day of signing, so the deal holds up as circumstances change. GenieAI can help you weigh each clause against your commercial position, and if you need to talk through a specific point before you sign, you can contact the team to walk through the draft and close the deal with confidence.
