It allows renewable sources such as wind and solar power to operate at full capacity during peak generation periods by storing excess energy until it is needed to meet later demand. (windpowerengineering.com)
At peak generation, this solar facility's electricity output would rival that of five large nuclear power plants. (insteading.com)
This will allow solar energy generators to store energy during peak generation times, and use the stored energy at peak price times. (foodandwaterwatch.org)
