Another roundup of European BESS news, this time around portfolios, partnerships, investments, financing, optimisation and tolling in France, Spain, Belgium, Denmark, Finland and Romania. Notable highlights are Grenergy’s 10-year BESS toll in Spain and Ingrid Capacity entering the French market.
This article follows our roundup yesterday, which looked at a swathe of battery energy storage system (BESS) project news in Finland, Estonia and Eastern and south-east Europe.
The ramp-up in European project development and financing activity is a positive step, and will be a big talking point at next week’s Energy Storage Summit 2026 in London.
Grenergy signs 10-year BESS toll in Spain

The toll is for its 150MW/600MWh Oviedo project, part of its pan-European investment platform ‘Greenbox’, revealed in May last year. At the time, it said Oviedo would start construction of the project in the first half of 2026 and that it would be operational in 2027.
Spain holds promise as a large-scale storage market but the business case and regulatory and policy environment still needs to be fleshed out. That’s according to Isabel Rodriguez de Rivera, managing director at Nuveen Infrastructure, who will be a speaker at the Summit event next week.
BESS projects in Spain are generally getting to bankability and investability either via subsidies or long-term tolls, and are often co-located with solar PV projects. Utility and power firm Iberdrola is helping drive the initial wave of projects, commissioning two last month that it said are the country’s largest.
Solaria procures 516MWh of BESS for Spain projects
In related news, IPP Solaria has purchased 516MWh of BESS products for projects in Spain, totalling €150 million (US$177 million) in investment.
The BESS will be added to eight of its existing solar PV plants: the El Baldío 2, Tordesillas 3, Valdelosa, Guleve, Draco, Juno 1, Santiz 1 and Pegaso projects. They will allow for more efficient management of generated energy, shifting production to higher-priced time slots, and reduce exposure to the volatility of the wholesale electricity market, Solaria said. It didn’t reveal the supplier from which it bought the BESS.
Ingrid Capacity enters France
Sweden-headquartered BESS platform Ingrid Capacity has partnered with French developer Wattmen to deploy 200MW across France. The projects are expected to reach ready-to-build (RTB) status in 2026 and 2027.
Ingrid is the leading developer and operator in Sweden and has also expanded into Finland, but this is its first foray outside of the Nordics.
“We continue to execute on our mission to make the European grid more intelligent. I am proud that we are now being trusted to provide our infrastructure and software to also the French energy market. Cross-border partnerships are necessary to deliver on the pressing needs of the European power grid”, said Axel Holmberg, CEO of Ingrid.
The firm launched its own optimisation platform in 2024 too, which Holmberg discussed with Energy-Storage.news.
BNP Paribas invests in BESS platform Eclipse
Bank BNP Paribas and BESS developer and trader Eclipse have partnered on BESS projects in France and Belgium.
BNP is making a strategic equity investment into Eclipse, which develops, owns, operates and trades projects with its proprietary algo trading software, Flowstream. It has a pipeline of 16 projects in France and Belgium totalling 850MW of capacity.
Eclipse said that the partnership with BNP Paribas provides asset owners with tailored financing solutions for BESS projects, as well as hedging instruments to manage merchant risk and reduce asset-level cost of capital. Eclipse and BNP Paribas will jointly offer long-term offtake solutions to the market. It essentially combines Eclipse’ BESS know-how and BNP Paribas balance sheet and creditworthiness.
Watts and Enervion ‘European’ partnership
Another partnership, but this time between engineering, procurement and construction (EPC) firm Enervion and BESS developer-operator Watts Group.
The pair have partnered to build BESS projects across Europe, they said last week (13 February). They are already working on four totalling 64MWh, which are scheduled to go live this year.
Watts has worked on projects in Switzerland, Germany and Finland, while Enervion is a Finnish company, though the pair didn’t say where those initial projects are.
R.Power agrees optimisation deal for 254MWh Romania project
Developer and IPP R.Power has signed a a long-term optimisation agreement with GEN-I for its 127MW/254MWh Scornicesti BESS project.
The Scornicesti project is co-owned with Eiffel Investment Group and is one of the largest energy storage facilities in Romania to have secured an optimisation contract, R.Power said. It started building the project last year.
It secured an optimisation deal for a 150MW/300MWh project in Poland last month with power firm Axpo, which will trade the BESS, and last year secured a ‘hybrid’ optimisation deal for a solar-and-storage project, also in Poland.
Financing for operational 200MWh co-located Denmark BESS
IPP European Energy has secured financing for its Kvosted hybrid solar PV and battery storage park in Viborg Municipality, Denmark.
The 50MW/200MWh BESS project came online last last year at the 100MW solar PV project, which had been operational since 2022.
The financing was provided by Ringkjøbing Landbobank A/S and the Nordic Investment Bank, with support from the EU’s InvestEU programme.
