Why Alcemi Bought Its Romanian Batteries From Individuals Rather Than a Development Platform

Alcemi has entered Romania with the acquisition of two battery storage projects, a 300 MW scheme at Medgidia and a 275 MW scheme at Șura Mare, both to be configured as four-hour systems for a combined 2,300 MWh. Enerdatics records the transaction at 575 MW with individual developers on the sell side, alongside a partnership with local developers Andrei and Emil Pop. Terms were not disclosed. It is the first move outside the United Kingdom for a developer that has spent four years building transmission-scale batteries with Copenhagen Infrastructure Partners. The counterparty is the most revealing detail in the announcement.

What did Alcemi acquire in Romania?

Alcemi acquired two development-stage battery projects totalling 575 MW, at Medgidia in Constanța county and Șura Mare in Sibiu county, each planned as a four-hour system for 2,300 MWh of combined energy capacity. Enerdatics logs the sellers as individuals rather than a corporate developer, consistent with the partnership Alcemi has struck with Romanian developers Andrei and Emil Pop, who bring local permitting and grid interconnection expertise. The consideration was not disclosed, which is standard at this stage of development. Alcemi co-founder James Forster framed the arrangement as a partnership rather than a clean purchase, with the local team retained to navigate regulation, interconnection and community engagement.

What does it mean when a market's sellers are individuals?

It means the market is young. In a mature battery market, development pipeline sits inside companies with balance sheets, permitting departments and staff, so buyers acquire the company in order to get the pipeline. In a young market the pipeline sits with individuals who secured land options and grid positions before institutional capital arrived, and it changes hands project by project. Enerdatics records individuals as the seller in the two largest Romanian battery transactions of 2026, covering 617 MW between them, which is the clearest signature of a market in its opening phase. The trade-off for a buyer is real. Entry is faster and cheaper because there is no corporate premium and no team to absorb, but there is also nothing to inherit: no repeatable origination engine, no permitting bench, and no second tranche of pipeline sitting behind the first.

Why is Alcemi expanding beyond the United Kingdom now?

Because its UK model is proven and largely spoken for. Alcemi partnered with Copenhagen Infrastructure Partners in February 2022 to develop a 4 GW UK portfolio through to final investment decision, and the results are visible in Enerdatics' records as a sequence of stake sales out of the resulting assets: 500 MW to AXA Investment Managers in April 2025, 500 MW to AIP Management in October 2025, and 500 MW to the Scottish National Investment Bank and the Nuclear Liabilities Fund in June 2026. That is a working machine, originating transmission-scale projects, carrying them to FID alongside institutional capital and selling down at construction. Romania offers somewhere to run the same sequence again, in a market where nobody has yet built an equivalent position.

Enerdatics' data shows just how early Romania is. The country recorded no standalone battery transactions at all in 2024, six in 2025 and five so far in 2026, eleven in total. Against that base, Alcemi's single 575 MW acquisition makes it the second-largest buyer of Romanian battery capacity on record, behind only the 2,400 MW position Strioga Family Foundation took from FF New Energy Ventures in September 2025, and ahead of Renalfa Group, RGreen Invest, Repono and Premier Energy. Pricing is effectively unobservable, with only one of the eleven transactions carrying a disclosed value: Hidroelectrica's 36 MW purchase at $18.22 million, or $0.51 million per MW. For scale, Germany logged 8 battery transactions in 2024, 21 in 2025 and 19 already in 2026, while Italy has recorded 26 since the start of 2024. Romania today sits roughly where Germany stood two years ago.

What does the deal signal for the Romanian storage market?

The deal signals that the institutional phase of Romanian storage has started, and that the individual developers who assembled the early pipeline are now the sell side. Romania has the conditions that make batteries valuable: rising renewable penetration, a constrained network, and a position at the eastern edge of the synchronous European grid. What it has lacked is capital willing to underwrite a market without a settled revenue framework, which is why the four-hour configuration matters. A four-hour system is a bet on capacity and energy-shifting revenue rather than on frequency response, and it is the configuration that pays if Romania follows Italy and Poland towards formal capacity procurement. Expect more UK and Nordic developers to arrive on the same reasoning, and expect the individual sellers to be largely gone within two or three years, absorbed into platforms.

The open question for Alcemi is whether the model travels. Its UK position rests on a four-year relationship with a single large capital partner and a pipeline deep enough to justify a permanent development organisation. In Romania it starts with two projects and a partnership with two individuals. Enerdatics' records put the country's entire battery M&A history at eleven transactions, so the depth of pipeline needed to repeat the UK sequence does not yet visibly exist. The 575 MW is a position rather than a platform, and the next acquisition will say considerably more than this one.

Key takeaways

• Alcemi entered Romania by acquiring two development-stage battery projects totalling 575 MW, a 300 MW scheme at Medgidia and a 275 MW scheme at Șura Mare, both configured as four-hour systems for 2,300 MWh combined. Terms were not disclosed.
• Enerdatics records individuals rather than a corporate developer on the sell side, alongside a partnership with Romanian developers Andrei and Emil Pop covering permitting and grid interconnection.
• Enerdatics data shows Romania recorded no standalone battery transactions in 2024, six in 2025 and five so far in 2026, making this an eleven-deal market in total.
• The acquisition makes Alcemi the second-largest buyer of Romanian battery capacity on record, behind only the 2,400 MW position Strioga Family Foundation took from FF New Energy Ventures in September 2025.
• Only one of Romania's eleven recorded battery transactions carries a disclosed price, Hidroelectrica's 36 MW purchase at $18.22 million, which leaves the market effectively unbenchmarked.

Frequently asked questions

How much did Alcemi pay for the Romanian battery projects?The consideration was not disclosed. Romanian battery pricing is close to unobservable: Enerdatics records only one of the country's eleven standalone battery transactions as carrying a disclosed value, Hidroelectrica's 36 MW purchase at $18.22 million, equivalent to $0.51 million per MW.

Where are Alcemi's two Romanian battery projects located?The 300 MW project is at Medgidia in Constanța county in the southeast, and the 275 MW project is at Șura Mare in Sibiu county in central Romania. Both are planned as four-hour systems, giving 2,300 MWh of combined energy capacity.

Who is Alcemi?Alcemi is a United Kingdom developer of large-scale, transmission-connected battery storage. It partnered with Copenhagen Infrastructure Partners in February 2022 to develop a 4 GW UK portfolio through to final investment decision, work that produced the Coalburn and Devilla projects in Scotland. Romania is its first market outside the United Kingdom.
