THE CHALLENGE

Over 100 gigawatts of capacity go unused every day.

The expansion of renewable energy is increasing grid instability. In the 4-5 sunniest hours around midday alone, more than 100 gigawatts of excess capacity are lost today because storage capacity is missing.

A powerful partner for the energy transition.

GESI develops, plans, builds and finances large-scale battery storage systems for energy suppliers and institutional investors.
