Pennsylvania's SREC market is oversupplied. A variety of federal and state incentives, in addition to the SREC market, led to a substantial build out of solar in the state. Additionally, PA is one of two remaining SREC states that allows systems to register from outside of the state, further impacting supply. For a period of time before January 2011, PA systems were eligible to apply to the DC SREC market.

Market prices

Solar requirement

Reaching 0.5% of total electricity generated in 2021.

Meter readings

Facilities less than 15 kW DC capacity (that did not receive funding from the PA Sunshine program) are eligible to produce SRECs from estimated generation based on NREL's PV Watts solar resource calculator. All other facilities must report monthly readings. Facilities that received Pennsylvania Sunshine funding and all systems larger than 15 kW require a revenue grade meter.

Eligibilty begins

At date of application to PA AEPS.


200% of the average SREC (solar AEC) price paid by power provider in that year. The Solar Alternative Compliance Payment (SACP) is the penalty price, that power providers must pay per SREC if they are unable to file the required number of SRECs at the end of the compliance period.

SREC useful life

3 years - a 2012 SREC (solar AEC) can be counted towards either the 2012, 2013 or 2014 compliance periods.

Source: EIA Report "Retail Sales of Electricity by State by Sector by Provider (EIA-861)" updated 3/23/15. Projected SRECs Required utilizes the most recent EIA electricity data applying an average 1.0% growth rate per forecast year. RPS Solar Requirement is multiplied by forecast total electricity sales to arrive at Projected SRECs Required. Projected Capacity Required is based on a factor of 1,200 MWh generated per MW of installed capacity per year. Projected Capacity Required assumes the amount of capacity needed to be operational all year to meet that year's RPS requirements with only current vintage SRECs.
