Markets and Operations
SPP's relationships with our members – some of which stretch back decades – are very important to us. Members drive our major decisions and future plans; we work together to ensure the region enjoys a reliable electric supply and economic well-being. SPP's collaborative and evolutionary approach resulted in the successful 2007 implementation of the real-time EIS (Energy Imbalance Service) Market. The EIS Market beat expectations in its first year, with a benefit to the footprint of $103 million – $17 million above initial estimates.
SPP began developing new energy markets in 2009 to bring additional regional benefit to our members. The Integrated Marketplace launched in 2014 – making SPP the first RTO to design, build and implement a Day 2 market on time – and includes a Day-Ahead Market with Transmission Congestion Rights, a Reliability Unit Commitment process, a Real-Time Balancing Market replacing the EIS Market and the incorporation of price-based Operating Reserve procurement. The Integrated Marketplace also consolidated the SPP footprint's 16 legacy Balancing Authorities into an SPP Balancing Authority.
NOTE: All Integrated Marketplace market data can be found on the Marketplace Portal.
The Market Monitoring page contains a description of the Market Monitoring responsibilities, periodic reports, completed investigation reports, FAQs and Offer Cap calculation data. The page also includes instructions on submitting a request for inquiry.
Locational Marginal Price (LMP) is the market-clearing price for energy at a given Price Node equivalent to the marginal cost of serving demand at the Price Node, while meeting SPP Operating Reserve requirements. It is calculated using a Security Constrained Economic Dispatch (SCED) and is the price to provide the least-cost incremental unit of energy at a specific location, while also considering congestion and losses.
