AEC eligibility update: Recent projects may still qualify for PA Tier II AEC certification, but AEC revenue is generated from certification forward — not retroactively. Some articles are temporarily under editorial review.

Our Services
Transform your energy efficiency investments into revenue through Pennsylvania's Tier II REC market.
We evaluate your energy efficiency projects and submit them as PA Tier II generation assets for REC creation and registration.
As a generation asset aggregator, we bundle multiple completed projects across the PJM territory to maximize REC production.
We clear RECs through RFPs and competitive markets, generating monetary incentives for asset owners from the sale of credits.
We handle submission of utility rebates through PPL, First Energy, and PECO for renovation and energy efficiency upgrades.
How It Works
Our streamlined 4-step process takes your completed energy efficiency projects and converts them into monetized RECs.
Share relevant project details through our submission form. Upload utility rebate documents if available.

Energy efficiency is only 0.5% of supply
The 2025 PUC AEPS Report projects a likely shortfall in Tier II credit supply beginning in 2028 as waste coal facilities — currently 50.5% of supply — continue to retire. With the 10% compliance obligation requiring 13.6M+ credits annually and 100% sourced from Pennsylvania, prices could approach the $45 ACP cap. Energy efficiency projects represent just 0.5% of current supply, signaling massive untapped opportunity for building owners to register qualifying projects now.
Act 114's in-state requirement, retiring waste coal generators, and a 10% compliance obligation have driven Tier II prices from $0.10/MWh in 2016 to $26 in 2025 — a 26,000%+ increase. Total Tier II compliance costs surged from $3.6M in 2020 to $367.6M in 2025. As prices approach the $45 ACP cap, now is the optimal time to register and monetize your energy efficiency projects.
