Installing Energy Storage at PJM (Video)

Energy storage can provide grid operators a reliable and flexible way to keep power supplies in balance as generation and load change throughout an operating day.

PJM has gained experience with storage technology on its campus with a two-megawatt array of lithium-ion batteries stationed at PJM’s campus. (The project is owned and operated by AES Energy Services LLC, a subsidiary of The AES Corp., a PJM member.) The array changes its output or electricity consumption in less than a second and helps PJM quickly balance short-term variations in electricity use.

Check out the below video to see how it was installed.
