Energy Storage Drives Grid Resilience

Across America, energy storage is a strengthening grids and delivering savings for ratepayers. SEIA’s Seth Miller explains how they work from the 200-megawatt West Wing facility developed by AES in Arizona.

How does energy storage keep power bills low?

By soaking up abundant and affordable solar energy during the day, energy storage is relied upon by grid operators to deploy excess power at the exact time that homes and businesses need it most.

How does energy storage help stabilize the electrical grid?

Grid operators must constantly balance power supply with real-time energy demand. Energy storage systems store extra energy produced during periods of low demand and discharge it back into the grid when energy demand peaks.

How does energy storage optimize clean energy resources?

Batteries soak up extra energy during times when the supply of electricity is greater than demand, like during the daytime when the sun is out. These systems then discharge the stored energy at times that demand rises, such as in the evening when less solar energy is produced. This maximizes the amount of clean solar energy within the overall resource mix.
