From LED lighting to variable frequency drives, dozens of energy efficiency measures qualify under PA Act 129 and the AEPS. Discover the full list of eligible technologies and documentation requirements.
With the ACP cap set at $45/MWh and supply constrained, the Tier II weighted average rose from $1.92 in RY2020 to $26.92 in RY2025 — a 1,300% increase in five years. Here's what drove it and what it means for project owners.
A step-by-step guide to assembling your documentation — utility rebate records, M&V reports, and invoices — and navigating the PA PJM-GATS registration process with ease.
Individual projects may generate modest REC volumes, but aggregating multiple sites across Pennsylvania can unlock premium pricing from LSEs facing compliance obligations.
Pennsylvania's Act 129 Phase V runs June 2026 through May 2031 with a $1.22 billion budget and 3.3 million MWh in savings targets. Here is what changed, EDC by EDC.
A 200,000 sq ft warehouse retrofitting 1,200 metal halide fixtures and adding VFDs to dock ventilation would save roughly 3,200 MWh annually — here is what that is worth in Tier II AECs, with the arithmetic shown.
In RY2025 Tier I non-solar averaged $29.29 and Tier II $26.92 — the two tiers have converged. What still separates them is the supply pool each is bid against.
Measurement and Verification (M&V) is the backbone of REC certification. Proper weather normalization and equipment specifications ensure your verified savings are maximized.
LSEs must demonstrate AEPS compliance annually. As Phase V ratchets up Tier II requirements, LSEs face a choice: buy RECs or pay the $45/MWh ACP penalty.
Forward REC contracts can serve as a financing tool, reducing payback periods on HVAC, lighting, and controls upgrades by 30–50%.
Pennsylvania runs the only liquid standalone market for efficiency-based credits among PJM states. North Carolina permits efficiency certificates inside its REPS; Ohio's limited mechanism expires after 2026.
