EPRI Short-Term Electricity Market Simulation Program

  • EPRI-STEMS provides a realistic simulation of electricity markets using an exact physical power system model provided by the EPRI-OTS, specific market model for all market participants and a host of goals by each market participant in a true market-based environment,
  • It implements FERC’s Standard Market Design for Day-Ahead and Real-Time markets with capabilities to take into account single and multi-part energy bids, ancillary service bids, network congestion, and many others,
  • Is flexible to accommodate additional market rules by various ISO’s and/or RTO’s
  • Can be effectively used by ISO’s/RTO’s, GENCO’s and ESCO’s
  • Is fully modular, CIM-compliant and takes advantage of existing proven technologies by EPRI, DSI and her partners/allies. The following figure illustrates the basic STEMS functional structure: (RTMS: Real-Time Market Simulator; FMA: Forward Market Administration)
