With the passing of Massachusetts Senate Bill 2768 in May 2009 (better known as the Green Communities Act) three additional classes of RECs were created in the RPS:
- Massachusetts Class II
- Massachusetts Class II Waste to Energy
- Massachusetts Alternative Portfolio Standard (APS) Credits
Since the inception of these markets, activity has been limited until today, where 2009 vintage Massachusetts APS Credits traded furiously from $16.50 up to $17.50 per credit. Evolution Markets brokered five MA APS transactions in this price range. The market is now being quoted $17.00 bid, offered at $18.25 per credit.
