GMP again uses battery storage to cut costs for customers

COLCHESTER, Vt. (WCAX) Green Mountain Power used stored energy again to bring down the cost of electricity for customers.

Back in July, GMP crews pulled power from 500 Tesla Powerwalls, as well as energy storage facilities in Rutland and Panton.

The energy was used during the July 5 peak day when temperatures soared. GMP Vice President Josh Castonguay says that saved customers $500,000.

Now, the numbers are in for a new peak day-- August 6.

A GMP spokesperson says 75 more Powerwalls were installed, and that's what helped save more money.

There is an estimated cost savings of $600,000.

A total of 2,000 Powerwalls are expected to be installed as part of a program between GMP and Tesla.
