Statkraft and Greenvolt Power have signed a 10-year tolling agreement covering two battery projects in northeastern Poland, with a combined capacity of 400 MW and 1.6 GWh. The deal marks Statkraft’s first large-scale battery storage contract in Poland; financial terms were not disclosed.
Statkraft has signed a 10-year tolling agreement with Greenvolt Power covering two battery energy storage projects in northeastern Poland, a combined 1.6 GWh of capacity. The agreement gives Statkraft the right to decide when the batteries charge and discharge across energy and flexibility markets, and marks its first large-scale battery storage contract in Poland, according to the companies.
The projects are Ełk and Turośń Kościelna, each rated at 200 MW/800 MWh. They are located in Nowa Wieś Ełcka and Turośń Kościelna, respectively, in the country’s northeast. Together, they can deliver up to 400 MW of power and store 1.6 GWh of energy. The published announcement does not disclose the agreement’s financial terms or specify when the tolling period begins.
Under the arrangement, Statkraft will control when the systems charge and discharge, seeking to participate in energy and flexibility markets. Greenvolt said the structure provides predictable long-term revenue alongside income from Poland’s capacity market. The Turośń Kościelna project is due to begin receiving capacity market revenue in 2028, according to the report.
The tolling contract was not required to finance construction or asset purchases, Energy Storage reported. Greenvolt secured financing from UniCredit in August, comprising €153 million in bridge facilities and a €65 million guarantee facility. Turośń Kościelna was inaugurated in July 2026, while Ełk was expected to reach commercial operation shortly, the report said. BYD Energy Storage supplied the battery systems.
A New Market Role for Statkraft
The deal gives Statkraft a direct role in operating large-scale battery storage in Poland, where the projects can shift electricity use over time and offer flexibility to power markets. For Greenvolt, the tolling structure assigns market optimization to Statkraft and is intended to add a long-term revenue stream to the projects’ business model.
The combined 400 MW power rating and 1.6 GWh storage capacity make the agreement a substantial commitment in the country’s battery sector. Energy Storage described it as one of Europe’s largest publicly announced battery storage agreements. That characterization is the publication’s assessment; the companies did not provide a comparative ranking in the quoted statements.
The projects also illustrate how storage revenues may come from more than one source. The tolling agreement covers market activity, while Turośń Kościelna is expected to receive capacity market revenue from 2028. The relative contribution of those revenue streams has not been disclosed.

Projects Nearing Operation
Greenvolt Power is the developer of the two utility-scale battery projects. The report says Turośń Kościelna was inaugurated in July 2026 and that Ełk was expected to reach commercial operation shortly after the September 29 announcement. An inauguration does not by itself establish that a project has begun commercial operation, and the report does not provide a confirmed operating date for either site.
In August, Greenvolt secured UniCredit financing consisting of €153 million in bridge facilities and a €65 million guarantee facility. The report says the tolling agreement was not needed to finance construction, build-out or asset purchases. The agreement therefore concerns the commercial operation and market optimization of the assets rather than the financing cited for their development.
Statkraft’s Polish activity has included other power agreements. Koronowski said the company had previously signed what he described as Poland’s largest corporate power purchase agreement and its first subsidy-free utility-based solar power purchase agreement. The source material does not provide further details about those earlier agreements.
Contract Terms Still Undisclosed
The announcement does not state the value of the tolling agreement, its precise start date, or the detailed allocation of risks and revenues between Statkraft and Greenvolt. It also gives no forecast for market earnings or for how often the batteries are expected to charge and discharge.
The reported commercial operation timing for Ełk was prospective: it was expected to reach operation shortly, but no confirmed date was supplied. The source also does not establish whether Turośń Kościelna had entered commercial operation after its July inauguration. The specific battery model was not identified in the report; it said only that BYD Energy Storage supplied the systems.
Commercial Operation and Market Entry
The next milestones are the projects’ commercial operation and the start of their participation in Polish energy and flexibility markets under the tolling arrangement. Ełk was expected to reach commercial operation shortly after the announcement, but a confirmed date has not been reported in the supplied source. The agreement’s start date and operational schedule also remain undisclosed.
For Turośń Kościelna, the report points to 2028 as the start of expected revenue from Poland’s capacity market. Further updates from the companies may clarify operating dates, the tolling contract’s financial terms and how the projects will combine market revenues with capacity payments.
Key Questions
What does the Statkraft–Greenvolt agreement cover?
It covers a 10-year tolling agreement for Greenvolt Power’s Ełk and Turośń Kościelna battery projects in Poland. Statkraft will decide when the batteries charge and discharge across energy and flexibility markets.
How large are the two battery projects?
Each project is rated at 200 MW/800 MWh. Together, they have 400 MW of power capacity and 1.6 GWh of storage capacity.
When will the projects begin operating?
Turośń Kościelna was inaugurated in July 2026, but the source does not confirm its commercial operation date. Ełk was expected to reach commercial operation shortly after the September 29 announcement; no specific date was given.
Did the tolling agreement finance construction?
No. Energy Storage reported that tolling was not required to finance construction, build-out or asset purchases. Greenvolt had secured financing from UniCredit in August, including €153 million in bridge facilities and a €65 million guarantee facility.
When could Turośń Kościelna receive capacity market revenue?
The report says the project is expected to receive revenue from Poland’s capacity market starting in 2028. It does not disclose the expected amount.
