Econergy has acquired full ownership of four operational battery storage projects in England, adding 106 MW of power capacity and 106 MWh of storage. The company says the portfolio could be upgraded from one-hour to three-hour duration, but those works are still under evaluation.
Econergy has acquired 100% of the holding company that owns four operational battery storage projects in England, adding 106 MW of power capacity and 106 MWh of storage to its UK portfolio. The independent power producer said the one-hour systems may be upgraded to three-hour duration, but it is still evaluating that work.
The purchase gives Econergy full ownership and control of the four assets, according to a filing to the Tel Aviv Stock Exchange cited by Energy Storage. The company did not identify the seller. The projects are standalone battery energy storage systems, each currently configured for one-hour storage; together, their stated capacity is 106 MW and their energy storage capacity is 106 MWh.
Econergy said the portfolio is expected to generate about £4.7 million in EBITDA in 2027, before planned augmentation works. EBITDA is a measure of operating earnings before interest, taxes, depreciation and amortization; the figure is a company projection, not a reported result.
The company is assessing whether to increase the systems’ duration to three hours. If completed as described, that would raise their combined storage capacity to about 318 MWh, while the reported power capacity would remain 106 MW. Econergy’s UK operational battery capacity rises from 90 MW to 196 MW, and its grid-connected operating assets increase from two to six.
Econergy Expands UK Operating Fleet
The acquisition more than doubles Econergy’s stated operational UK battery power capacity, giving it a larger base of assets already connected to the grid rather than relying only on projects under development. That may strengthen the company’s ability to participate in electricity markets, although the source material does not specify the four sites’ revenues, contracts, or operating arrangements.
The proposed duration upgrades could let the batteries store and deliver energy over a longer period. Econergy said this would allow the assets to shift electricity to periods of stronger demand and respond more flexibly to market conditions. Those benefits depend on the upgrades proceeding and on market conditions; the company has not announced a final investment decision or a completion schedule for the work.
The reported £4.7 million 2027 EBITDA estimate offers an indication of the expected earnings contribution before augmentation, but it is a forecast. The acquisition’s price and financing terms were not included in the available report, limiting what can be said about its cost or expected returns.

From Two UK Sites to Six
Before the acquisition, Econergy had 90 MW of operational UK battery capacity. Its existing assets include the 50 MW / 100 MWh Swangate project in West Melton, Yorkshire, which entered operation in 2024, and the 40 MW / 120 MWh Dalmarnock project in Glasgow, which connected to the grid in October 2026.
The purchase is part of a wider UK development effort. Econergy says it has a 1.6 GW UK energy storage pipeline. Across Europe, the company reports a battery storage portfolio totaling 5.9 GW, of which 3.3 GW is expected to be connected to the grid, under construction, or in pre-construction by 2028. These are company portfolio figures and describe a mix of development stages, not operating capacity.
““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 Undisclosed
The available report does not name the seller, disclose the acquisition price, or provide transaction financing details. It also says public registry transfer filings had not yet been made to Companies House at the time of reporting. The reported stock-exchange filing establishes Econergy’s disclosure, but further public records may clarify the transfer.
The proposed move from one-hour to three-hour duration remains under evaluation. Econergy has not stated when it would decide, how much the work would cost, whether it has secured required approvals, or when the assets could be upgraded. The 2027 EBITDA figure is the company’s estimate before that work, and no separate earnings forecast after augmentation was provided.
Watch for Filings and Upgrade Decisions
Further transaction detail may emerge through public registry records or additional company disclosures, including the seller’s identity and the purchase terms. Econergy’s next substantive decision on the portfolio will be whether to proceed with augmentation and, if so, to provide a timetable and investment details.
For now, the confirmed development is a change in ownership and an increase in Econergy’s operational UK capacity. The three-hour configuration and its potential commercial benefits remain plans under evaluation, rather than completed upgrades.
