In most U.S. markets, the SCUC/SCED procedure co-optimizes energy and operating reserves. The output from the DA market clearing therefore includes schedules for energy and operating reserves. In addition, LMPs are derived for each transmission node, and market clearing prices are also calculated for each category of operating reserves. The prices are used in the financial settlement of the DA market. Note that most intermittent resources are currently not bidding into the DA market, but are being treated as price-takers in the RT market.
