S4 Energy is at the forefront of the rapidly evolving energy sector, specializing in large-scale Battery Energy Storage Systems (BESS). These systems are key to stabilizing the grid and enabling the seamless integration of renewable energy sources like wind and solar.

When I wanted to make my business more sustainable and was looking for a way to heat my greenhouses without CO2 emissions, I made the choice to partner with S4 Energy. In S4 Energy, I found the team to develop the plan from concept to reality. S4 Energy has completely taken care of everything for me, and soon there will be an energy storage installation here that helps reduce grid congestion and heats my greenhouses!
As an energy producer and supplier, we understand the importance of having flexibility in the electric grid, especially in today's context. The importance is only set to increase in the future. We trade the capacity of S4 Energy's current energy storage systems, which has bolstered our portfolio with a substantial share of flexible capacity.
