Abstract

A method and apparatus for resolving energy imbalance in a real-time manner is disclosed. A plurality of market user interfaces are coupled to an imbalance engine which determines optimal dispatch requirements corresponding to supply and demand requirements of the market participants. The imbalance engine resolves in a real-time manner the dispatch requirements while considering the transmission limitations, ramping limitations, transmission facilities, and price data.

Claims

1. A pricing engine coupled to a system for receiving pricing information from market participants for balancing the load requirements for energy imbalance in an energy trading market, said pricing engine comprising:

means for generating optimal pricing parameters for dispatch instructions; and

means for generating optimal ex-post and ex-ante price parameters for said dispatch instructions.

2. The pricing engine of claim 1, wherein said pricing engine generates billing price as ex-ante locational marginal price.

3. The pricing engine of claim 1, wherein said pricing engine generates billing price as bid price.

4. The pricing engine of claim 1, wherein said pricing engine generates billing price based on the worst price for said market participant.

5. The pricing engine of claim 1, wherein said pricing engine calculates billing prices, quantities and charges in five minute intervals.
