Investment and IPP news from across Europe, with DTEK buying a BESS project in Poland, Ingrid inaugurating one in Sweden and Triodos investing in a German portfolio.
DTEK’s DRI buys 112MW Poland BESS from Greenvolt
Ukraine-based energy investor and operator DTEK, via subsidiary DRI, has acquired its second large-scale battery energy storage system (BESS) project in Poland.
It has acquired the ready-to-build (RTB) 122MW/448MWh BESS in Kozienice, eastern Poland, from developer and independent power producer (IPP) Greenvolt Group.
It comes just a few days after DTEK/DRI progressed its first large-scale Polish BESS, acquired from developer Columbus Energy, with the hiring of system integrator Fluence to deploy it for a 2027 commercial operation date.

Greenvolt has a policy of selling 70-80% of the assets it develops internally and retaining 20-30%, and is putting a very large portfolio of BESS into operation itself in Poland, recently ordering 1.6GWh of BESS from BYD and enlisting optimiser Entrix for the projects. The firm won the bulk of BESS contract wins in the 2023 capacity market (CM), which its deputy commercial director for Europe discussed with ESN Premium a year later.
The CM is the bedrock of the business case for BESS in Poland and, while it was praised at Solar Media’s Energy Storage Summit Central and Eastern Europe (CEE) 2025 this week by panellists, they also said the country lacks precise and long-term regulations and targets around storage.
Ingrid Capacity and SEB put first partnership BESS into operation in Sweden
BESS developer-operator Ingrid Capacity and investor SEB Nordic Energy Fund, via its Locus Energy arm, have inaugurated a 12MW/12MWh BESS in Rättvik Municipality, Sweden.
The project is the first in a larger partnership between the two companies, said to total 196MW when it was announced in September 2024 but now pegged at 172MW/240MWh, an average duration of 1.4-hours.
Alongside project development and construction, Ingrid Capacity now also oversees optimisation with its own trading platform, which it will use for this project.
“Our proprietary AI-powered trading platform adds the intelligence that makes the grid smarter and more efficient. This creates stability and value not only here in Rättvik, but also in many other places across the Nordics,” said Nicklas Bäcker, co-founder and chief strategy officer at the company.
Ingrid has already deployed a 211MW BESS portfolio in Sweden in which BESS platform BW ESS became a majority owner of in 2023.
Triodos enters BESS in Germany with two project financings
The clean energy investment arm of bank Triodos has entered the BESS market in Germany via a partnership with developer Icecreek Energy, starting with two projects totalling 16.6MW/35.6MWh of capacity.
It is the Triodos Energy Transition Europe Fund’s first investment in the German BESS market. The fund is financing the capital expenditure for the two projects in Alsdorf and Vordorf, expected to become operational in late 2025 and early 2026.
Icecreek Energy is a German developer BESS at the medium-voltage level founded in 2024.
Entrix, the same optimiser enlisted by Greenvolt in Poland, will provide trading and optimisation on the two German projects for Icecreek/Triodos.
The BESS will be deployed and integrated by second life specialist Voltfang, which this week also announced a separate long-term partnership for BESS in Germany with investor Palladio Partners. Energy-Storage.news interviewed both companies this week and will publish the results of that in the coming week.
Triodos has been active in financing BESS elsewhere in Europe, including in the UK, Netherlands and Belgium.
