Price Reversals in New England Under Sequential Auction
n1.1. Operating Reserves Market Flaws: TMSR, TMNSR, TMOR.
n During June and July the ISO identified design flaws in the operating reserve markets of Ten Minute Spinning Reserve (TMSR), Ten Minute Non-Spinning Reserve (TMNSR), and Thirty Minute Operating Reserve (TMOR).  The operating reserve design flaws resulted in markets that are not workably competitive.  In a competitive market, higher quality goods should command higher prices.  In the operating reserves markets prices did not appear to be reflective of costs and lesser quality reserves received higher prices.  For example, Thirty Minute Operating Reserve (“TMOR”) is less useful than Ten Minute Non-Spinning Reserve (“TMNSR”), Ten Minute Spinning Reserve (“TMSR”), or Energy.  However, at times, TMOR prices exceeded the prices for all three of the other products.
