Pennsylvania’s Alternative Energy Portfolio Standard creates ongoing SREC revenue for solar system owners, but only when registration and metering are handled correctly. For installers, that means interconnection, net metering, and GATS setup must be part of the closeout process, not an afterthought. This guide covers Pennsylvania net metering and SREC essentials for 2026.
Net Metering Under the Pennsylvania PUC
Pennsylvania utilities provide retail-rate net metering within defined system size caps. Applications run through PECO, PPL Electric Utilities, Duquesne Light, and FirstEnergy companies (Penelec, Met-Ed, West Penn Power). Incomplete one-line diagrams and missing PE stamps are common rejection reasons. Align the building permit plan set with the utility package from day one.
SRECs and PJM-EIS GATS
Pennsylvania Solar Renewable Energy Certificates are tracked in PJM-EIS GATS. After Permission to Operate, systems must be registered so SREC production can be sold into the PA AEPS market. Clean as-built drawings and accurate nameplate data speed registration. Athol Energy includes GATS-ready documentation in our as-built drawings and interconnection closeout.
Philadelphia, Pittsburgh, and the Township Landscape
Pennsylvania has more than 2,500 local jurisdictions under the Uniform Construction Code. Philadelphia permits through L&I and frequently involves rowhome structural questions. Pittsburgh routes through PLI and Duquesne Light. Many townships use third-party plan reviewers, which rewards checklist-complete submissions. Statewide support is outlined on our Pennsylvania solar design services page.
Bottom Line for Installers
Treat net metering and SREC registration as part of the design package. Complete plan sets, PE stamps where required, and GATS-ready as-builts turn Pennsylvania PTO into revenue faster. Start with permit design and interconnection coordinated together.
