The PA Tier II AEC weighted average rose from $0.09/MWh in RY2016 to $26.92 in RY2025. Here's every reporting year, what drove each move, and what comes next.
Variable frequency drives on pumps, fans, and compressors qualify for PA Tier II AECs. Here's how VFD projects are measured, what they're worth, and how to register.
Insulation upgrades, window replacements, and air sealing qualify for PA Tier II AECs in some cases. Here's what qualifies, what doesn't, and how to stack with utility rebates.
Pennsylvania hospitals and health systems with CHP, LED retrofits, or HVAC upgrades can generate significant Tier II AEC revenue. Here's what qualifies and how to register.
Pennsylvania manufacturers with compressed air upgrades, motor efficiency projects, and process improvements qualify for PA Tier II AECs. Revenue guide and registration walkthrough.
Pennsylvania's Alternative Energy Portfolio Standards Act 213 of 2004 created the Tier II AEC market. Here's what the law requires, how it's evolved, and what it means for generators.

PJM-GATS is the official tracking system for PA Tier II AECs. Here's how it works, why it matters, and what happens inside GATS when your project generates credits.
Curtailment is a documented reduction in electricity consumption, and § 75.63 issues AECs per MWh conserved. The revenue is incremental — here is what it is actually worth.
PA Tier II AECs are issued per MWh of electricity conserved. A geothermal retrofit that displaces gas heating can raise electricity consumption while lowering total energy use — producing real savings and no credits.
Office parks combine interior lighting on office hours with garage and exterior lighting running dusk to dawn. The two profiles behave differently, and modeling them separately changes the answer.
Wastewater treatment plants running digester gas CHP face a real classification question. Biogas is a Tier I resource; sub-5 MW CHP is a Tier II resource. At RY2025 prices the tiers are within a couple of dollars — what differs is the supply pool and the forward outlook.
