Houston, TX, October 12, 2005 — The Energy Authority (TEA) successfully completed the Southwest Power Pool’s (SPP) recent participant readiness testing through the use of The Structure Group’s nMarket software platform.
The SPP-led connectivity testing provided market participants the opportunity to test their ability to submit and query resource plans, ancillary service plans, energy imbalance service offer curves and SPP notifications in a controlled and scripted environment before proceeding with further market trials. During the testing, TEA verified it could successfully operate within the parameters handed down by the SPP, according to Bill Clarke, RTO implementation manager for TEA.
“The ability to communicate with SPP is a critical aspect of serving our members in and near the SPP footprint,” Clarke said. “nMarket reduced the complexity of TEA’s integration efforts with the RTO because the software allowed us to focus on internal system integration and other pertinent areas of operation rather than diagnosing how to communicate with SPP,” he said.
The SPP Energy Imbalance Service (EIS) market will include an imbalance market for real-time energy. Locational imbalance pricing (LIP) will be utilized to ensure that the lowest cost assets offered into the SPP EIS market are dispatched. The EIS market will be settled hourly.
“nMarket’s automation capability is much preferred to doing things manually,” Clarke said. “For example, the software’s automated settlement functions give TEA a tool for com-paring SPP’s settlement statements and TEA’s own ‘shadow’ statements to check for inconsistencies.” Also, nMarket adheres to SPP business rules, added Clarke.
SPP participant readiness testing was a success for Structure clients because Structure was able to translate its knowledge of wholesale energy markets into the nMarket software, according to Structure’s SPP product marketing manager Scott Quin.
