nMarket completes successful test

Houston, TX, Nov. 21, 2005 — The Structure Group announced that its nMarket software platform successfully supported Calpine Corp.’s energy services subsidiary, Calpine Merchant Services Co. (CMSC), through the Southwest Power Pool’s (SPP) recent Participant Readiness Testing.

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, CMSC verified it could successfully operate within the parameters handed down by the SPP.

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.

Structure’s nMarket software platform provides bid-to-bill, straight-through processing for companies participating in predominantly physical markets. The product will assist CMSC by performing all data communication to and from the market operator (submits, notifications, queries), warehousing real-time market decision support information (clearing prices, volumes/forecasts, meter reads, billing determinant information) and allowing CMSC to bid directly into the various markets, perform shadow settlements and track disputes with SPP.

SPP Participant Readiness Testing was a success for Structure clients because Structure made early investments in attending market readiness, tariff and protocol meetings to translate the rules into nMarket in time for the first market tests, according to Structure principal Michael Cutler.

SPP is expected to administer several more phases of market trials throughout the year. Day-in-the-Life testing is currently scheduled for November and will include additional functionality and more complex business testing. The unscripted portion of market trials is anticipated in late February leading up to the final trials.

A third release of the nMarket product will be made available in support of Enhanced Day-in-the-Life testing scheduled for late January. Enhanced Day-in-the-Life will be the first test of SPP’s upgraded systems along with the first test of Native Load Scheduling (NLS) and the settlements process.

The selection of the nMarket platform brings to three the number of installations in SPP, including the recently completed successful implementation at The Energy Authority.
