SRECs are part of energy programs created by a state legislature, not the federal government. State programs (usually called a Renewable Portfolio Standard, or "RPS") require that electricity providers claim a specific number of SRECs each year, which is what creates market demand for SRECs. Since each state sets its own RPS, demand for SRECs varies considerably.
Solar installations are different across states as well, setting market supply at different levels in different SREC markets.
RPS legislation also sets a price ceiling on SRECs (called a Solar Alternative Compliance Payment, or "SACP") which, like SREC demand, is set by the state's schedule.
