LED Retrofit REC Revenue: Real Pennsylvania Numbers

LED Retrofits: The #1 Qualifying Project for PA Tier II RECs

LED lighting retrofits account for more PA Tier II REC registrations than any other project type — and for good reason. They deliver substantial, easily verifiable kWh savings with well-documented measure lives of 10+ years.

But how much revenue can your specific LED project generate? Let's look at real numbers.

The Revenue Formula

REC revenue from an LED retrofit depends on three variables:

• Annual kWh savings = (Old wattage − New wattage) × Number of fixtures × Annual operating hours
• Annual RECs = Annual kWh savings ÷ 1,000 (to convert to MWh)
• Annual revenue = Annual RECs × Market price per REC ($26.92/MWh, RY2025 weighted average)

Revenue by Facility Size

Here's what typical LED retrofits generate across different building types:

• Small office (25,000 sq ft): Replacing 200 fluorescent fixtures with LED typically saves 75,000 kWh/year, generating approximately 75 RECs worth $1,650/year or $16,500 over 10 years.
• Mid-size commercial (75,000 sq ft): A full retrofit of 600+ fixtures commonly saves 225,000 kWh/year — roughly 225 RECs generating $4,950/year or $49,500 lifetime.
• Large warehouse/retail (150,000 sq ft): High-bay LED replacements in warehouses and big-box retail often save 500,000+ kWh/year, producing $11,000+/year or $110,000+ lifetime in REC revenue.
• Multi-building portfolio (500,000+ sq ft): Property management firms and REITs with multiple Pennsylvania locations can aggregate savings across their portfolio, often generating $30,000–$75,000/year in combined REC revenue.

What Makes LED Projects Ideal for RECs

• Easy to verify: The wattage reduction per fixture is straightforward — old fixture watts vs. new fixture watts multiplied by quantity and operating hours.
• Strong documentation: Most LED retrofits have detailed invoices with fixture counts, and many buildings received utility rebates that include pre-calculated savings figures.

Long measure life: LED retrofit equipment carries a 15-year TRM measure life. This equipment life is not imposed by Act 129: its separate fifteen-year cap governs the utility's benefit claim for the plan-level total resource cost test, not how long customers earn credits (66 Pa. C.S. § 2806.1(m)). Lighting controls, by contrast, carry 8 years, so a fixtures-plus-controls project runs on two clocks.

Existing projects may still qualify: LED retrofits that remain operational and verifiable can be certified. Credits are generated from the date a complete application is filed with the administrator, not from certification, over the remaining measure life, per 52 Pa. Code § 75.63(i).

Maximizing Your LED REC Revenue

To get the most from your LED project's RECs:

• Document everything: Keep invoices, spec sheets, and any rebate paperwork. These accelerate the registration process.
• Include all areas: Don't forget parking garages, exterior lighting, signage, and emergency lighting — they all count toward your total savings.
• Install [energy monitoring](https://emergentmetering.com): Real-time kWh metering provides the strongest possible savings verification and can reveal additional savings beyond the lighting circuit.
• Act quickly: Issuance begins when a complete application is filed, so every month unregistered is a month the measure runs without earning credits — the earning window simply starts later.
