Why the number is what it is
What is actually driving this
ISO New England capacity costs
Eversource buys from the same ISO New England wholesale market as every other New Hampshire 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
Eversource 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
Net metering in New Hampshire is locked until 2041
New Hampshire runs NEM 2.0, which credits solar exports at roughly 85% of the retail rate — specifically 100% of supply and transmission charges plus 25% of the distribution charge.
What makes it unusual is stability. NEM 2.0 is locked through 2041 under RSA 362-A, which is one of the most durable net metering policies in New England. Systems up to 100 kW qualify as residential.
Community power aggregation changes your supply rate but not your delivery charges, and net metering credits are calculated off your utility rather than your supplier. So joining community power and going solar are separate decisions that stack rather than conflict.
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.

Eversource questions
The things people actually ask
Why is Eversource's Price to Compare lower than PPL's but the all-in rate higher?
Because the two numbers measure different things. Eversource'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. New Hampshire is deregulated, and switching suppliers changes only the supply portion of your bill.
