We build for people
Our mission is to accelerate the transition to a fully renewable society. As the grid evolves, stability and flexibility become critical and grid-scale battery storage is essential to balancing the power system. Backed by deep expertise, decades of experience, and secured financing, we are building a diversified, pan-European portfolio of high-quality BESS assets designed for long-term ownership and operation.
Tailored to your every need

In order to accelerate the growth of our portfolio we purchase ready-to-build projects in Europe.
Construction & Operation
We finance and manage the construction of BESS projects that form a part of our portfolio, specialising in the procurement and sizing of the system.
Who we are
Founded in 2022 and headquartered in Switzerland, Delta Capacity develops, acquires, owns, and operates utility-scale battery storage assets across Europe. The company is scaling rapidly while maintaining a strong focus on asset quality, prioritizing high availability, efficient performance, and bankable operating outcomes. With nearly 800 MWh currently under construction and a 1 GWh pipeline targeted for 2026, Delta Capacity operates across the Nordics, Central and Southern Europe and delivers projects end-to-end — from early development through procurement, construction, and commissioning — with a clear pathway to build and operate more than 6 GWh of flexible assets by 2030.
