Econergy has acquired four operational battery storage projects in England with 106 MW of combined power capacity and 106 MWh of storage. The deal takes its operational UK battery capacity to 196 MW; the company is evaluating upgrades that could raise the sites’ total storage duration from one hour to three hours.
Econergy has acquired 100% of the holding company that owns four operational battery storage projects in England, adding 106 MW of power capacity to its UK portfolio. The sites currently have one hour of storage, and Econergy says it is assessing upgrades that could extend them to three hours.
The acquisition was disclosed in a filing to the Tel Aviv Stock Exchange, according to Energy Storage’s November 4 report. The four standalone battery energy storage system (BESS) projects have a combined 106 MW power rating and 106 MWh of storage at their current one-hour duration. The filing says the purchase gives Econergy full ownership and control through the acquired holding company.
Econergy expects the portfolio to generate about £4.7 million in EBITDA in 2027, before planned augmentation work, the company said. EBITDA is a measure of operating earnings before interest, tax, depreciation and amortisation; the figure is a company forecast, not reported earnings already achieved.
The company is evaluating a potential expansion from one-hour to three-hour duration. If completed, that would raise the sites’ combined storage capacity to about 318 MWh, while their stated power capacity would remain 106 MW. Econergy’s operational UK BESS capacity rises from 90 MW to 196 MW, and its number of grid-connected operating assets increases from two to six.
A Larger Operating UK Battery Fleet
The purchase expands Econergy’s operating footprint in the UK electricity market, rather than adding only projects in planning or construction. Operational storage can charge and discharge electricity in response to market conditions, while a longer storage duration could let the batteries hold energy for more hours before dispatch. Econergy said the proposed augmentation could allow the sites to shift electricity to periods of stronger demand and capture additional value.
That potential depends on upgrades being carried out and on the commercial conditions under which the assets operate. The reported £4.7 million 2027 EBITDA estimate applies before planned augmentation, and the available report does not give an investment cost, a schedule for the upgrades, or a post-upgrade earnings forecast. The acquisition adds scale, but those details are needed to assess its likely returns.
The deal also changes the balance of Econergy’s UK portfolio: operating capacity reaches 196 MW, against a stated 1.6 GW development pipeline. The difference underlines that projects in a pipeline are not equivalent to assets already connected and operating.

Econergy’s Existing UK Assets
Before this deal, Econergy had two operational UK battery projects, according to the source report. The 50 MW / 100 MWh Swangate BESS in West Melton, Yorkshire, entered operation in 2024. The 40 MW / 120 MWh Dalmarnock project in Glasgow connected to the grid in October 2026. Together, the sites account for the company’s existing 90 MW of operational UK capacity.
Econergy said it has a 1.6 GW UK energy storage development pipeline. Across Europe, it reports a BESS portfolio of 5.9 GW, of which 3.3 GW is expected to be connected to the grid, under construction or in pre-construction by 2028. Those figures describe a broader pipeline and do not mean that all of the capacity is operating or guaranteed to be completed.
The latest four projects are described as standalone batteries in England. The source report does not provide their individual site names or locations, and their current combined 106 MWh capacity matches the stated one-hour duration at 106 MW.
“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
Econergy has not named the seller, according to the report, and public registry transfer filings had not yet appeared at Companies House at the time of publication. The source material does not state the purchase price, the transaction’s completion date, or the specific locations and names of the four sites.
The move to three-hour duration remains under evaluation. Econergy has not provided a confirmed construction schedule, upgrade budget, or indication that all four sites will be expanded. The £4.7 million EBITDA figure is a forecast for 2027 before planned augmentation, not a guaranteed result; no post-upgrade forecast or assumptions behind the estimate are given in the source.
Completion Filings and Upgrade Decision
Further details may emerge through company disclosures or Companies House filings, including the seller’s identity and the formal transfer of the holding company. Econergy has also said it is evaluating augmentation of the four batteries. A decision, timetable and cost for that work have not been reported.
The next material developments for the portfolio are whether the proposed three-hour configuration is approved and implemented, and whether the operating sites meet Econergy’s stated earnings expectations. Until those details are disclosed, the confirmed change is the acquisition of four operating projects and the increase in Econergy’s reported UK operational capacity to 196 MW.
