FREQUENTLY ASKED QUESTIONS ABOUT ENERGY STORAGE

Source: Energy Storage Association Why is energy storage important? Energy storage fundamentally improves the way we generate, deliver, and consume electricity.  Energy storage helps during emergencies like power outages from storms, equipment failures, accidents or even terrorist attacks.  But the game-changing nature of energy storage is its ability to balance power supply and demand instantaneously - within miliseconds - which makes power networks more resilient, efficient, and cleaner than ever before. How… Continue Reading

CASE STUDY: Frequency Regulation Services and a Firm Wind Product: AES Energy Storage Laurel Mountain Battery Energy Storage (BESS)

Source: Energy Storage Association Opportunity AES Laurel Mountain is a 98MW wind power generation plant located in Belington, WV that is built to supply more than 260,000MWh of renewable energy annually to the PJM Interconnection. However, since wind generation is variable, wind power plants are unable to supply capacity services to assist with grid reliability… Continue Reading
