Each class and subclass of RPS and APS has its own percentage obligation for compliance; those percentages rise each year in the case of RPS Class I and APS, but not for RPS Class II. Beyond 2020 the RPS Class I and APS programs are scheduled to continue to grow annually at 1% and 0.25% respectively. The RPS I Solar Carve-Out, RPS Solar Carve-Out II, and RPS Class II Renewable Minimum Standards are set each August for the following year; the standards are based on formulas that take into account current market conditions. Each year the Retail Suppliers must show that they have purchased a sufficient amount of Renewable Energy Certificates (RECs), Alternative Energy Certificates (AECs), Waste Energy Certificates (WECs), Solar Renewable Energy Certificates (SRECs), and Solar Renewable Energy Certificate IIs (SREC IIs) to meet the Minimum Standard for that class. In general, the Retail Supplier determines the number of certificates that are needed each Compliance Year by multiplying their total annual sales times the Minimum Standard.
