Alstom software paves the way for a standard market design for regional transmission organizations

April 3, 2002 — ALSTOM announced Wednesday that its software product e-terracommit has successfully demonstrated its ability to solve large resource commitment problems associated with large-scale regional transmission organizations, paving the way for a standard market design.

The e-terracommit product, developed by the Energy Management and Markets Business within ALSTOM’s Transmission and Distribution Sector (T&D), provides forward scheduling of generation resources.

In recent tests, conducted in conjunction with PJM Interconnection L.L.C. (PJM), which operates the world’s largest wholesale electricity market, the latest version of e-terracommit( convincingly demonstrated its ability to successfully handle a system design containing 3,150 generating units, 355,000 MW of capacity, and a study peak demand of 300,000 MW – more than five times larger than PJM’s system, and larger than the Midwest Independent System Operator (MISO), PJM, and Southwest Power Pool (SPP) systems combined.

In addition to operating the world’s largest competitive wholesale electricity market, PJM also manages one of North America’s largest power grids. Recently, PJM, MISO and SPP announced plans to form a joint and common energy market, which would serve 26 states, the District of Columbia and the Canadian province of Manitoba.

A prevailing issue surrounding a standard market design for emerging large Regional Transmission Organizations (RTOs) has been concern regarding the ability of the technical software to solve large unit commitment problems. This concern has been addressed and resolved by ALSTOM’s e-terracommit(.

“The ability to address large-system models, using standard PC equipment, and to do so securely and successfully, is critical to the nation’s development of standardized market designs, ” said JD Hammerly, Vice President, ALSTOM T&D Energy Management and Markets America.
