Green Mountain Power has asked Vermont regulators for permission to lift the cap on its popular residential energy storage programs to expand customer access to battery backup power.
GMP’s Powerwall program, in partnership with Tesla, and its Bring Your Own Device battery backup program are capped at 500 new customers per program a year. The Powerwall program is full for 2023, a waitlist for 2024 has maxed out, and 250 customers are on a waitlist for 2025, GMP said in April.
