Why the number is what it is
What is actually driving this
ISO New England capacity costs
Green Mountain Power buys from the same ISO New England wholesale market as every other Vermont utility. Capacity auction prices have climbed sharply and pass through to customers.
Data center demand
Large computing loads across the ISO New England footprint are arriving faster than new generation is being built, and the transmission to serve them is recovered from ratepayers.
Quarterly resets
Green Mountain Power adjusts its Price to Compare four times a year rather than twice. That means smaller individual changes but more of them.
The honest cost picture
Why Vermont rates sit above the national average
Vermont buys wholesale power through ISO New England, the same market that sets prices for Massachusetts, Connecticut, Rhode Island, Maine and New Hampshire. When capacity and energy prices rise there, they land across the region rather than utility by utility.
Vermont’s rates are lower than most of New England but still 28% above the national average, and the state has strong net metering rules plus a renewable energy standard that supports residential solar.
The practical point for a homeowner is that every kilowatt-hour your roof produces is one you stop buying at 21¢ — and that number has moved in one direction for a decade.
Two ways to pay for solar, and they are very different
If you buy the system
You own the equipment, you keep any renewable energy credits, and you carry the maintenance responsibility. Installed pricing varies by roof, shading and system size.
If you use a PPA
$0 upfront. We install and own the system; you buy the power it produces at a rate set in your agreement, and you only pay for what it actually generates. The system owner carries maintenance for the life of the agreement.
The residential federal tax credit (25D) ended for systems purchased after December 31, 2025.
You will still see ads promising a 30% credit that “ends December 31.” Read the date on them. If you buy a system today as a homeowner, you cannot claim that credit. What remains applies to the owner of the system — which, under a PPA, is us. SolarAmerica does not provide tax advice; talk to your tax professional about your situation.

Green Mountain Power questions
The things people actually ask
Why is Green Mountain Power's Price to Compare lower than PPL's but the all-in rate higher?
Because the two numbers measure different things. Green Mountain Power's supply charge is lower; its distribution charges and riders are higher. What matters to your budget is the all-in figure — your bill divided by your kilowatt-hours.
How often does this change?
Four times a year: March, June, September and December.
Can I shop for supply?
Yes. Vermont is deregulated, and switching suppliers changes only the supply portion of your bill.
