The projects will be deployed in the SE3 region, which includes Stockholm and surrounding areas, and the first of them will become operational in 2026.

Centrica is already active in the BESS market with large-scale projects in both the UK and abroad (in Belgium, for example), though this is its first foray into Sweden. The firm has in-house optimisation capabilities through its Centrica Business Solutions arm.

The energy storage market in Sweden has picked up in the last few years as investors and developers capitalise on high ancillary service prices. A c.200MW pipeline was recently launched by Ingrid Capacity and SEB, while commercial and industrial (C&I) sites are also launching large-scale systems, such as Hydro and Arctic Paper.

Nordic Solar to build 10MWh BESS in Denmark, eyes 1GWh pipeline

International developer and IPP Nordic Solar has entered the BESS market with a 10MWh project on home soil, in Denmark.

The BESS will be in Borup in the municipality of Hillerod on Zealand and will be the first of many more BESS projects for the company. It is adding BESS to solar projects it has already been developing and the total energy storage capacity planned is close to 1GWh, across 25 sites.

Nordic Solar, which has been covered by our colleagues at PV Tech, didn’t say when the 10MWh BESS would come online, just noting that it was now launching construction on the project.

Niam and Evecon to deploy portfolio with 26MW of BESS

Investment firm Niam Infrastructure and developer Evecon will together deploy a solar-and-storage portfolio in Latvia that could have up to 26MW of BESS capacity.

The portfolio will be built in two phases, with construction at the first, including 40MW of solar generation capacity across six sites, already underway, and expected to be commissioned by the end of March 2025. The second phase will see the construction of five sites, with a combined power generation capacity of 44MW, and Evecon expects to begin construction before the end of this year.

Evecon will also build 26MW of battery energy storage systems (BESS) at the project sites, but did not specify the timeframe for the construction and commissioning of these facilities.

Upon commissioning, the projects will be jointly owned and operated by Niam Infrastructure and Evecon, and the companies announced that they will explore “various offtake strategies”, including power purchase agreements (PPAs), at the projects, but that nothing had been signed yet.
