PPL serves Lancaster, Lebanon, Adams, most of Dauphin County, and the Lehigh Valley. Supply rates rose 20% in 2025 alone — driven by PJM capacity costs surging over 800% from the prior year.
A $15 billion AI data center campus is under construction in Carlisle, 20 miles from Harrisburg, connecting directly to PPL’s transmission system. That 1.35 gigawatt load — expandable to 1.8 GW — lands on the same grid PPL customers depend on. Infrastructure investments to support it are recovered through future rate cases.
Residential solar panels Pennsylvania PPL customers install today lock in a fixed rate regardless of what the next PJM capacity auction clears.

The January 2025 distribution hike was instituted to recover the $230 million fine FirstEnergy was issued for bribing government officials.
Met-Ed’s $382 million LTIIP III grid rebuild (approved December 2024) will be recovered through future rate cases. PJM capacity costs — who Met-Ed buys their energy from — surged over 800% in 2024 and continue to drive quarterly supply resets.
Pa solar panels for Met-Ed customers lock in a rate below the current 20.4¢ all-in — a rate that doesn’t move with any of these resets.

The Mid-Atlantic data center corridor running through southeastern Pennsylvania is one of the densest in the country. That demand is a primary driver of the PJM capacity price explosion — costs that PECO passes directly through to customers via quarterly supply rate adjustments. Additional capacity cost phase-ins are expected through December 2026.
Solar energy Pennsylvania PECO customers generate on their rooftop locks in a rate below the current 20¢ — insulated from every future quarterly reset.

The reason is structural: DLC’s customer base is significantly smaller than PPL (1.5M) or PECO (1.6M). Fixed infrastructure costs — grid modernization, legacy industrial equipment, transmission upgrades — are spread across fewer ratepayers. The same PJM capacity cost pressure hitting every PA utility hits DLC customers harder on a per-customer basis.
December 2025 brought the largest single supply rate increase of any major PA utility — DLC raised the residential Price to Compare 41% in a single reset. Pennsylvania solar installer options for DLC customers offer the largest absolute dollar savings of any utility in the state.

The cost of solar panels PA homeowners pay upfront is zero. With a $0 down PPA, you pay only for the electricity the system produces — at a rate locked below what your utility charges. No installation fees, no equipment costs, no maintenance bills. The 60-second quiz calculates your exact savings based on your specific utility and monthly bill.
PJM Interconnection — the wholesale energy market that all four PA utilities buy power from — saw capacity auction prices surge over 800% in 2024. Data center growth, retiring power plants, and transmission bottlenecks drove the spike. Every PA utility passes those costs directly through to customers via quarterly supply rate resets. It isn’t a one-time event: the underlying forces are structural and ongoing.
All four raised rates significantly. PPL raised supply rates 20% in 2025. Met-Ed raised supply 24.6% in the past year. PECO raised all-in rates over 20% since early 2025. Duquesne Light has the highest all-in rate of any major PA utility at approximately 23¢/kWh — and took the largest single-reset increase of any PA utility in December 2025. Pennsylvania solar installer options for all four utilities offer fixed rates locked below the current utility price.
Net metering measures the difference between electricity pulled from your utility’s grid and electricity your solar panels send back. During daylight hours, surplus flows to the grid and your utility credits your account at the full retail rate. Those credits cover your needs at night and in winter when your panels produce less. Pennsylvania’s Alternative Energy Portfolio Standards Act requires PPL, Met-Ed, PECO, and Duquesne Light to offer 1:1 net metering to residential customers — meaning if you put $1 of energy onto the grid, you get $1 back.
Plan for four to seven months total from signing to system activation. Utility interconnection approval (PPL, Met-Ed, PECO, or Duquesne Light) typically takes one to three months. After approval, installation and final township inspections take one to four additional months. Starting today means your system could be live before the next round of rate resets.
The 60-second quiz uses your actual utility rate to calculate exactly how much solar panels PA would save you — Year One and over 25 years. Free, no obligation, no pressure.
