The state’s largest utility says it saved its customers about $3 million this year by using a network of energy storage devices, including Tesla batteries in homes and solar sites, to cut demand during energy peaks, especially during the hot, dry summer.
Green Mountain Power said batteries installed through its programs for customers also provided more than 16,000 hours of backup power to get through outages, which has become increasingly important as Vermont has seen more severe weather because of climate change, according to the utility. Also, Vermonters have spent more time at home because of the pandemic.
The network of storage devices includes home batteries, utility-scale Tesla Power Pack batteries at solar sites and electric vehicle smart chargers.
“Energy storage programs like this are delivering meaningful results, showing a path to help the economy, while reducing costs and carbon at the same time,” Green Mountain Power President and Chief Executive Officer Mari McClure said in a statement.
Green Mountain Power offered two home battery programs this summer: the Bring Your Own Device and Powerwall programs. The Bring Your Own Device Program, offered in conjunction with Renewable Energy Vermont, offers customers up to $10,500 toward the purchase of home storage batteries of your choice. You then agree to share your stored energy during times of peak demand.
The Powerwall program offers two Tesla Powerwall batteries for your home on a 10-year lease for $55 per month, or one payment of $5,500. Again, you agree to share energy during peak demand. The program is full, but new spots will open up in January.
The Bring Your Own Device program still has some spots available for 2020. Each program can enroll about 500 customers per year.
