Why the number is what it is
What is actually driving this
PJM capacity costs
Pepco buys from the same PJM wholesale market as every other Maryland utility. Capacity auction prices have climbed sharply and pass through to customers.
Data center demand
Large computing loads across the PJM footprint are arriving faster than new generation is being built, and the transmission to serve them is recovered from ratepayers.
Quarterly resets
Pepco 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 Maryland and Delaware bills keep climbing
BGE, Pepco and Delmarva Power are all subsidiaries of Exelon. Maryland’s Office of People’s Counsel has noted that since Exelon acquired BGE in 2012, electric rates have nearly doubled and gas rates have more than tripled.
The distribution side — the part you cannot shop away by switching suppliers — is where most of the increase sits. That is also the part solar offsets, because every kilowatt-hour your roof produces is one you do not pay distribution charges on.
In 2026 the PJM capacity auction cleared at its maximum price, driven largely by data-center demand arriving faster than new generation. Maryland’s Office of People’s Counsel estimated the resulting monthly increases at roughly $21 for BGE customers, $14 for Pepco, $18 for Potomac Edison and $4 for Delmarva Power.
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.

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