Energy storage is a critical component of any initiative to make electric power and mobility more sustainable. As more solar and wind power generation are added to the electric grid, a mismatch between the periods of peak generation and peak demand necessitate some way to store energy and buffer transient fluctuations in the grid.
The economics and benefits of energy storage, especially combined with renewables is compelling. Grid benefits, in particular, are amazing for a grid that needs to grow. Energy storage provides really fast frequency response (sub 4 seconds) that far exceeds the value and stability of conventional central plants.
A grid-connected system allows you to power your home or small business with renewable energy during those periods (daily as well as seasonally) when the sun is shining, the water is running, or the wind is blowing.
