GVEC members with Enphase IQ batteries are incentivized to join the program with one initial bill credit upon registration and an on-going annual bill credit based on the capacity rating of their system. During times of high demand throughout the year, GVEC, working in conjunction with Parsons (formerly IPKeys Power Partners) and Enphase, can access up to 70% of the total capacity of each battery system to discharge back into the home reducing or eliminating the home’s reliance on the grid.
