RTP ESP Aggregation

Energy Service Provider (ESP) collects energy and ancillary services bids and offers from RTP and other DER subscribing customers. The ESP combines those bids into an aggregate bid into the market operations bid/offer system. When accepted, the ESP notifies the end customer of the status and requests scheduling of the services.

Energy Service Provider (ESP) collects energy and ancillary services bids and offers from RTP and other DER subscribing customers. The ESP combines those bids into an aggregate bid into market operations. The incoming bids are prioritized and based on price, quality and size. Bids may be based upon distributed generation or other resource such as deferrable load or switch-able capacitors for reactive power supply/voltage support. These bids are combined and offered into the market operations bid/offer system. Market Operations evaluates the bids against the energy and ancillary services needs in the system based upon the load forecast, energy schedules and marginal costs for generation. Market operations will notify the ESP of acceptance of the bids and requests that the services be scheduled. The ESP then determines the best set of customer bids to meet the accepted aggregate bid. The ESP then notifies the selected customers of the accepted bids and requests that the services be scheduled.

It is possible that Market Operations may issue new RTP base tables if the energy bids significantly effect marginal costs. If so an iteration of the RTP pricing process may be initiated if the tariffs allow for such.

Some customers may be subscribers to independent energy and ancillary services aggregation provides who intern offer into Market Operations bid/offer system. This use case deals specifically with ESP RTP customers.
