In areas where the power system has been deregulated, the costs presented in this session should be considered to be ballpark costs as low load levels may cause power producers to sell power at a loss rather than to incur shutdown and startup costs. Conversely, at high load levels with congestion pricing in effect, power producers may be able to increase profitability.
