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.
Yeah, if you want to go fully off-grid, it’s a lot more expensive; you need enough batteries to store full overnight power, and you need enough solar panels to charge them on a cloudy day in winter. It’s cheaper to do an on-grid system where you generate as much electricity as you use over the course of a year, which is a lot more common.
