A Power Auction proceeds in a series of rounds. When a participant bids, they are stating the number of "tranches" (quantity) they are willing to supply of each product at the prices in force at that point in the auction. A price for a product is an amount (e.g. in $/kW hour) paid for each unit of account (e.g. kW hour) of a "product" (e.g. full requirements service) purchased. The auction is called a Simultaneous Auction because products for all zones or sellers are auctioned at the same time and bidders can switch between products as the relative prices develop. The auction is a descending auction because the going prices for over-subscribed products decrease as the auction progresses from round-to-round. Participants reduce the quantity they wish to supply as the going prices decrease. The auction closes when the total number of tranches bid on each product is less than or equal to the auction volume. The auction's starting prices are the going prices in the first round. The final auction prices are the clearing prices at the auction close. Those bidders holding the final bids when the auction closes are the winners.
