Customer Services - RTP ESP Aggregation Function
Contents
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.
