Econergy has acquired full ownership of four operational battery storage projects in England with a combined capacity of 106 MW. The deal raises its operational UK battery capacity from 90 MW to 196 MW; the company is evaluating upgrades that could extend the sites from one-hour to three-hour duration.
Econergy has acquired 100% of the shares in a holding company that owns four operational battery storage projects in England, adding 106 MW of capacity to its UK portfolio. The purchase lifts the independent power producer’s operational UK battery capacity from 90 MW to 196 MW, according to a filing disclosed to the Tel Aviv Stock Exchange.
The four standalone battery energy storage system (BESS) sites have a combined power capacity of 106 MW and currently provide one hour of storage, equivalent to 106 MWh in total. Econergy said it is evaluating plans to augment them to three-hour duration, which would bring their combined storage capacity to about 318 MWh. The company has not said that the upgrades have been approved or scheduled.
Econergy said the projects are expected to generate about £4.7 million in EBITDA in 2027, before planned augmentation works. That is the company’s forecast, not a reported result. The filing did not identify the seller, and the report said public filings recording the transfer had not yet appeared at Companies House.
The acquisition expands Econergy’s UK operating portfolio from two grid-connected assets to six. Its existing projects are the 50 MW / 100 MWh Swangate BESS in West Melton, Yorkshire, which began operating in 2024, and the 40 MW / 120 MWh Dalmarnock project in Glasgow, which connected to the grid in October 2026.
Econergy More Than Doubles UK Capacity
The purchase gives Econergy a larger base of operating storage assets in the UK, rather than adding only projects still in development. Battery systems can store electricity and release it later; longer-duration equipment can hold more energy and deliver it across a longer period. Econergy said that moving the acquired sites to three-hour duration could help them respond to changing market conditions and shift electricity to periods of stronger demand.
The potential upgrade is not yet a completed part of the deal. For now, the acquired portfolio remains at one-hour duration, and the company has not disclosed investment costs, a timetable, or a final decision on augmentation. Those details will affect how much additional storage the sites ultimately provide and how the forecast earnings compare with the cost of operating and upgrading them.
The deal also increases Econergy’s exposure to the UK market as it pursues a wider pipeline. The company says it has 1.6 GW of UK energy storage in development. That figure describes projects at development stage, not operating capacity, and should be distinguished from the 196 MW now reported as operational after the acquisition.

From Two UK Sites to Six
Econergy’s UK operating portfolio before the purchase consisted of Swangate and Dalmarnock. Swangate is a 50 MW / 100 MWh facility in West Melton, Yorkshire, and entered operation in 2024. Dalmarnock, a 40 MW / 120 MWh project in Glasgow, connected to the grid in October 2026. Their combined 90 MW matches the operating-capacity figure Econergy said the new acquisition raises to 196 MW.
The company reported a broader European battery portfolio of 5.9 GW. It said 3.3 GW is expected to be connected to the grid, under construction, or in pre-construction by 2028. These are portfolio and development figures; they do not mean that all 5.9 GW is operating or that all 3.3 GW is guaranteed to be completed by that date.
““We’re pleased to be purchasing these four projects, which represent a business opportunity with clear upside.””
— Eyal Podhorzer, Econergy CEO and director
Seller and Upgrade Plans Not Disclosed
The available report does not name the seller, disclose the purchase price, or provide the acquisition’s completion date. It also says that Companies House transfer filings were not yet available when reported, so public registry details had not independently identified the transaction.
Econergy has not confirmed whether it will proceed with the proposed three-hour upgrades, how much they would cost, or when any work might take place. The 2027 EBITDA figure is a company expectation and is specified as being before planned augmentation works; the report does not provide assumptions behind the forecast or an estimate of earnings after upgrades.
Watch for Filings and Upgrade Decisions
Further information may emerge through company disclosures and Companies House records, including confirmation of ownership transfers and, potentially, details of the seller or transaction structure. Econergy’s next relevant update would be whether it approves the proposed duration upgrades and provides a schedule, cost estimate, or revised capacity figures.
Until those details are disclosed, the firm’s confirmed operating-capacity addition is 106 MW at one-hour duration. The possible increase to about 318 MWh of storage and the stated 2027 earnings forecast should be treated as plans and projections, not completed outcomes.
