IN Brief:
- Octopus Renewables Infrastructure Trust has conditionally agreed to acquire the 55 MWp Barnsdale Solar Park for about £34.6 million, including construction expenditure.
- Goldbeck Solar is delivering the scheme near Leeds, with an approximately 40 MWac rating and connection planned through Ledston Primary substation.
- The purchase depends on conditions linked to a Contract for Difference expected to commence in March 2027, with revenue arrangements running until 2041.
OnPath Energy has agreed the conditional sale of Barnsdale Solar Park in West Yorkshire to Octopus Renewables Infrastructure Trust (ORIT), in a transaction valued at approximately £34.6 million including remaining construction costs. The 55 MWp photovoltaic development is already under construction between Kippax and Allerton Bywater, east of Leeds, and is expected to connect to the electricity network later in 2026.
The companies have signed an agreement rather than completed an acquisition. ORIT's purchase depends on the project satisfying conditions ahead of its Contract for Difference (CfD) commencement deadline, which the investment trust expects in March 2027. The development is being delivered by Goldbeck Solar, a contractor that has previously worked with ORIT on its Breach solar project in Cambridgeshire.
Barnsdale has an installed photovoltaic rating of 55 MWp and an alternating-current output rating of approximately 40 MWac. The two measurements describe different parts of the same plant: the peak rating represents the nominal output of the photovoltaic modules under standard test conditions, while the AC figure relates to the equipment and connection through which electrical power can be exported. Neither represents continuous generation, because output changes with irradiance, module temperature and equipment availability.
OnPath's project information identifies Ledston Primary substation as the connection point. Photovoltaic modules generate direct-current electricity, which is collected through cabling and converted to alternating current by inverters. Transformers, switchgear, metering and protection equipment are then needed to connect the installation to the receiving network at the required voltage and within its agreed export limits. The company has not published the final inverter arrangement or detailed protection settings.
Those interfaces remain part of the project's completion requirements. Installation of solar modules and mounting structures does not establish that the generating plant can export electricity commercially. Before operation, the contractor and network parties need to complete the electrical works and verify controls, metering, fault protection and the response of the plant at its connection point. The newly announced sale does not constitute confirmation that those tests have finished.
Goldbeck Solar's construction programme began in 2025, following earlier access and enabling works. OnPath says the completed scheme will produce electricity equivalent to the annual consumption of up to 19,000 homes. That is a comparison based on expected annual energy output, not a claim of a dedicated supply connection to those households. Production will vary with weather and maintenance, and the plant must remain within the operating conditions of its network connection.
The government-backed CfD provides a separate commercial framework. Barnsdale received a contract through the fifth CfD allocation round, and ORIT identifies its arrangement as fixed-price and linked to consumer price inflation, with a term running until 2041. The mechanism provides defined remuneration conditions for eligible electricity generation, but revenue still depends on metered output and compliance with the contract. It should not be confused with a guarantee that the plant will run at its AC rating throughout the year.
The March 2027 date is particularly important to the transaction. ORIT expects the conditions required for acquisition to be satisfied ahead of the CfD commencement deadline. Although OnPath anticipates a network connection in 2026, the announcement does not say that the transfer of ownership, commercial operation and all CfD-related requirements will occur simultaneously. Each milestone requires its own confirmation.
The reported £34.6 million is a total acquisition amount inclusive of outstanding construction expenditure. It is therefore not a separately disclosed cash price for an already operating asset, nor a new EPC contract value. The companies have not broken down the consideration, remaining construction payments or completion adjustments. Treating the entire amount as the value of the electrical equipment would overstate what the disclosure establishes.
The transaction also changes the future investment position of the developer and purchaser without immediately changing the installation's engineering requirements. ORIT is pursuing construction-stage investment opportunities alongside disposals elsewhere in its portfolio. OnPath intends to recycle proceeds from asset sales into its pipeline of further renewable projects. Neither company has announced a change in Goldbeck Solar's construction scope or the site's grid connection timetable arising from the agreement.
OnPath has identified ecological works, habitat management and a 106% biodiversity net gain commitment for the development. These form part of the site's wider construction obligations, alongside access tracks and the placement of solar equipment. The solar arrays cover only part of the development boundary, and the ecological commitments should be kept separate from the electrical capacity and production figures used to describe the plant.
A previously submitted proposal for battery storage at Barnsdale does not establish that storage equipment is included in the present 55 MWp acquisition. The October transaction statements describe a solar project and do not specify an operational battery installation, battery equipment procurement or a storage capacity figure. The electrical scope can therefore be reported accurately without adding an unconfirmed storage component.
Work will continue on the solar installation and its connection through Ledston Primary substation. The expected 2026 connection and March 2027 CfD deadline leave a series of construction, testing and contractual milestones before the conditional sale can be treated as complete. Until then, Barnsdale remains an under-construction solar development subject to an agreed but unfinished acquisition.
