Spot-Price Marketing Of Surplus Energy By The Sharing Of Interruptible Loads In A Regional Power Pool

The problem addressed by this paper is the curtailment of directly-controlled interruptible loads (and subsequent loss of an energy market) due to: pool capacity obligations at a time when the regional power pool has a surplus of coal, hyd ro; and/or nuclear generation. The approach taken by MAPP is unique in that one pool member'ss load can be offered to other pool members for service via a spot-pricing mechanism, with the relative energy costs at the time determining whether non-firm load is served or interrupted. This approach is intended to take advantage of the existing load; diversity within the pool. The additional non-firm load served under these conditions has no additional requirement for operating or planning reserves. An innovative feature of this approach is the procedure for quantification/certification of interruptible load.
