terralayr addresses the massive deficit in global energy storage.
The over-indexing of electricity generation from renewable energy sources leads to large volatility on the energy grid. The main problem is that wind and solar farms are fluctuating and, by definition, unsteady—there is no sun at night, and it is not always windy. This increases the need for flexibility in the form of battery storage systems to balance the grid in times when supply and demand do not match.
By buying and developing grid-scale storage assets and virtually aggregating them across a layer, we are creating the world's first energy cloud. Imagine AWS for energy. Through the flexibility we secure, we can market flexibility-as-a-service and hedging products/power insurance to utilities, SMEs, and industrial players and create virtual storage capacity for PV and wind farms.
