Platts, part of S&P Global Energy, proposes to change the frequency of several US Renewable Energy Certificate (REC) price assessments from weekly to daily, effective July 1, 2026.
Platts is proposing to move five prices to a daily frequency to provide more transparency to the market and to better reflect liquidity:
