Pennsylvania: AEC, PPL/PECO rebates, and Act 129.
Pennsylvania has no declining-block solar tariff. The case is built from Alternative Energy Credits, utility rebate and efficiency programs under Act 129, retail rate structure, and the federal credit.
The rule in one paragraph
The Alternative Energy Portfolio Standards Act requires electric suppliers to source a share of load from alternative energy, creating a market for Alternative Energy Credits that solar projects generate and sell. Act 129 requires utilities including PPL and PECO to run energy efficiency and demand response programs, which fund rebates for qualifying commercial measures.
Because Pennsylvania is a retail-choice market, the supply rate and the distribution charges have to be read separately when modeling the value of on-site generation.
Primary source: PPL Electric — Act 129 rebates and stakeholder programs.
Who it applies to
Commercial and industrial customers of Pennsylvania electric distribution companies, including PPL, PECO, Met-Ed, Penelec and Duquesne Light service areas.
Rebate eligibility and program budgets are set per utility and per program year, and budgets can close mid-year.
What it costs / what it pays
AEC prices are market-set and move, so a Pennsylvania model should be stress-tested across a credit-price range rather than a single point.
Act 129 rebates are not automatic: they apply to qualifying measures, at values and budgets set per utility and program year. Act 129 Phase V runs June 2026 to May 2031. Demand response participation can add a separate payment stream for a battery where the project qualifies.
How NOI's structure fits
The project agreement determines who carries AEC price risk, handles applications and operates the equipment, and whether the owner receives savings, payments or both.
For Pennsylvania industrial assets, demand charges and supply-rate volatility usually drive more of the case than the credit market does.
