Vermont Utility Plans to End Outages by Giving Customers Batteries

From NY Times.com (Oct. 9, 2023):

Green Mountain Power is asking state regulators to let it buy batteries it will install at customers' homes, saying doing so will be cheaper than putting up more power lines.

Many electric utilities are putting up lots of new power lines as they rely more on renewable energy and try to make grids more resilient in bad weather. But a Vermont utility is proposing a very different approach: It wants to install batteries at most homes to make sure its customers never go without electricity.

The company, Green Mountain Power, proposed buying batteries, burying power lines and strengthening overhead cables in a filing with state regulators on Monday. It said its plan would be cheaper than building a lot of new lines and power plants.

The plan is a big departure from how U.S. utilities normally do business. Most of them make money by building and operating power lines that deliver electricity from natural gas power plants or wind and solar farms to homes and businesses. Green Mountain — a relatively small utility serving 270,000 homes and businesses — would still use that infrastructure but build less of it by investing in television-size batteries that homeowners usually buy on their own.

"Call us the un-utility," Mari McClure, Green Mountain's chief executive, said in an interview before the company's filing. "We're completely flipping the model, decentralizing it."

Like many places, Vermont has been hit hard this year by extreme weather linked to climate change. Half a dozen severe storms, including major floods in July, have caused power outages and damaged homes and other buildings.

Those calamities and concerns about the rising cost of electricity helped shape Green Mountain's proposal, Ms. McClure said. As the company ran the numbers, it realized that paying recovery costs and building more power lines to improve its system would cost a lot more and take a lot longer than equipping homes with batteries.

This is what happens when a state completely relies on green energy. Although, decentralizing the power grid isn’t too bad an idea especially if someone hacks the grid or natural disaster or even just break downs.
