S4 Energy - Who and where

Why and What

Battery storage is key to addressing climate change and the transition to a more sustainable energy future.

Renewable energy sources are domestic and inexhaustible reducing vulnerability to supply disruptions and geopolitical tensions. But they are intermittent.

Energy storage is a critical for transforming our energy systems into being cleaner, more reliable, and more efficient. It supports the integration of renewables, enhances grid stability, provides backup power, reduces emissions, and offers numerous economic and environmental benefits.

What our partners say

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.
