- Tesla and Vermont utility Green Mountain Power have partnered to offer backup battery power to residential customers for just $15 per month, less than half the cost of a similar pilot the utility ran two years ago.
- The price drop comes from improvements in battery capacity and energy output, Greentech Media reports, along with control software developed by SolarCity to help provide grid benefits.
- The Powerwall 2 units will be offered to up to 2,000 customers, and could help reduce peak load by 10 MW— the equivalent to taking an average of 7,500 homes off the grid.
