Stack Utility Rebates + RECs from the Same Project
You can claim both PA utility rebates from PPL, PECO, or FirstEnergy AND PA Tier II RECs for the same energy efficiency project. They're completely separate programs — learn how to stack these incentives.
Combined Revenue from One Project
Example: 150,000 sq ft commercial building — LED retrofit + HVAC upgrade
Utility Rebate (one-time)
$22,000
PPL / PECO / FirstEnergy
Annual REC Revenue
$14,300/yr
650 MWh × $22/MWh
Total Combined Value
$165,000+
Rebate + 10-year RECs
Qualifying Energy Efficiency Measures
LED Lighting Retrofits
Interior, exterior, high-bay, parking garage, and signage upgrades
Typical savings
2.5–4.5 kWh/sq ft
HVAC System Upgrades
RTUs, chillers, heat pumps, boiler replacements
Typical savings
3.0–5.0 kWh/sq ft
Variable Frequency Drives
VFDs on fans, pumps, compressors, and process motors
Typical savings
1.5–3.5 kWh/sq ft
Compressed Air Optimization
Leak repairs, VSD compressors, pressure reduction
Typical savings
1.0–2.5 kWh/sq ft
Building Automation Systems
BAS, EMS, scheduling, and controls upgrades
Typical savings
1.0–2.0 kWh/sq ft
Building Envelope
Insulation, windows, air sealing, cool roofs
Typical savings
0.5–1.5 kWh/sq ft
How Incentive Stacking Works
These programs are administered by different entities with independent eligibility. You can — and should — pursue all available incentives from a single project.
Utility Rebate
One-time incentive from PPL, PECO, or FirstEnergy
Type
One-time payment
Typical Value
$15,000–$30,000
PA Tier II RECs
Annual credits through PJM-GATS for 10–15 years
Type
Recurring annual
Typical Value
$5,000–$15,000/yr
Federal Tax Incentives
179D deduction or ITC for qualifying equipment
Type
Tax benefit
Typical Value
Varies by project
Strengthen Your Application with Energy Monitoring
Installing energy monitoring and submetering on your upgraded systems provides real-time M&V data that strengthens both your rebate applications and REC registrations. Verified kWh data accelerates approvals and maximizes credit volumes.
Whether you're metering lighting circuits, HVAC systems, or VFD-controlled motors, real consumption data is the gold standard for savings verification.
Projects Completed in the Last 10 Years Still Qualify
Don't assume it's too late. Energy efficiency projects completed within the last decade are eligible for retroactive REC registration. Every month you wait is revenue permanently lost.
