Previous Day Market Summary
The market summary for the previous day operation compares the actual market results to the projections prepared for that day. The first table compares forecasted demand and reserve requirements with the actual operating results. The four sample points,
The second table in this report summarizes the total generation offers and demand bids that were submitted for the previous day to meet the system demand and reserve requirements. The total bids and offer gives a broad indication of the available supply for energy and reserve in the market. Note however that the level of supply may be reduced by existing constraints in the system.
The summary of the generation and reserve schedules reflects the total capacity of resources that were cleared in the market for dispatch scheduling. A comparison schedules with the total bids and offers and the demand forecast will indicate the adequacy of supply for energy and reserve in the market.
The resulting average prices are compared with the projected prices on the fourth table. The comparison is also shown graphically below this table. Energy prices presented are load-weighted average marginal prices as presented in the real-time market report. Reserve prices are based on regional reserve clearing price in the market.
The reports are updated and published at
