Construction underway at R.Power’s 150MW / 300MWh Jedwabno BESS

31 March 2026

R.Power, a pan-European Independent Power Producer (IPP) with a fast-growing multi-technology portfolio, has announced that construction is underway at its utility-scale Battery Energy Storage (BESS) project in Jedwabno, Poland.

The 150MW / 300MWh Jedwabno BESS project is one of Poland’s largest energy storage projects in construction, directly supporting the nation’s ambition to transition away from coal and stabilise its grid.

Scheduled for completion at the end of 2026, the project has secured revenues through a 17-year contract in Poland’s capacity market auction and a long-term optimisation agreement with Axpo.

Having laid the groundwork for Jedwabno commercially, we’re pleased to be making strong headway on construction of the project, drawing on the experience of our construction team in collaboration with trusted European EPC contractor Nomad Electric. This team will ensure the robust delivery of a utility-scale energy storage system that contributes directly to Polish energy security.

Marcin Pajewski, Chief Technical Officer at R.Power

Construction is being led by appointed contractor Nomad Electric, Nomad Electric Group’s dedicated EPC arm, with civil works currently in progress.

After the expansion of PV, utility-scale BESS is the natural next step and a game-changer that will transform how the entire EU power grid operates. At Nomad Electric Group, we are driving this shift by building and managing critical infrastructure from power grids to hybrid plants. We deliver the large-scale capacity that powers the continent’s energy transition.

The construction of Jedwabno BESS builds on R.Power’s 12+ years of experience bringing renewable energy projects online across Europe. It follows a period of substantial construction activity for R.Power which has seen 53 new renewables and BESS projects connected to the grid in 2025, plus a further ten projects in the first quarter of 2026.

R.Power’s EPCM team has now connected more than 1GW of renewables and energy storage capacity, spanning Poland, Portugal and Romania, 800MW of which sits within its operational IPP portfolio. A further 585MW is currently under construction across Poland, Portugal, Romania and Germany.

As the scale and technological diversity of R.Power’s pan-European pipeline grows, further construction and grid connection milestones in the past year have included:

Construction and grid connection of R.Power’s first hybrid solar-plus-storage project at Nehrybka,
Completion of R.Power’s first two Romanian PV projects, Sat Suseni and Stalpu,
Start of construction at the 55MW Lazuri high-voltage connected in Romania,
Start of construction at the 20MW Kloetze PV project, R.Power’s first in Germany,
Start of construction at the 80MW PSE-connected Lasocice project,
EPC agreements signed for the 127MW / 254MWh utility-scale Scornicesti BESS in Romania (due to enter construction in Q2 2026).

Our market-leading construction management capabilities sit right at the heart of R.Power’s expansion plans. We have active construction projects simultaneously underway across Poland, Romania, Germany and Portugal, including high- and medium-voltage PV and BESS, all overseen by our in-house EPCM team, working alongside trusted European contractors. At the peak of our construction activity in 2023, we were connecting a new project to the grid almost every other day. Now we are turning the same expertise to larger, more technically complex projects that will form the backbone of our pan-European, multi-technology portfolio.
