About ERCOT Nodal

March 10, 2010, VANCOUVER, B.C., Canada -

March 10, 2010 – Richmond, B.C. − As ordered by the Public Utility Commission of Texas (PUCT) in September of 2003, ERCOT will be moving from a Zonal to Nodal Wholesale Market in Texas. This transition involves moving from a grid system divided into Congested Management Zones (CMZs) to one comprising of nearly 4000 nodes. The new system is intended to increase reliability and create more efficiently managed operations.

  • Improved price signals due to a more granular pricing model
  • Improved dispatch efficiencies resulting in lower overall cost of power supply
  • Direct assignment of local congestion – settlement prices based on locational marginal prices

The transition is currently in the 3rd stage of the Market Trials, after 1 more stage of Market Trials the official changeover will likely go live in fall 2010. Once the transition has been implemented, consumers of ERCOT Zonal data will no longer have access to the market data; providing detrimental implications to market players.
ZE PowerGroup Inc. (ZE) has taken a proactive approach to this transition much like the preparation for the Market Redesign and Technology Upgrade MRTU program developed by the California Independent System Operator (CAISO). As developers of ZEMA™ Suite, the leading Enterprise Data Management solution, ZE has been preparing for the transition since early 2009. As this transition has significant implications for our clients, ZEMA has dedicated resources to ensure complete and timely market data from ERCOT is accessible to ZEMA users as soon as the new data is published. For ZEMA users, the transition will be seamless and the new data will be manageable on day one of implementation.
The preparation for the ERCOT transition is just one example of how the ZE provides its clients with superior service. The ZEMA software applications are supported by the expertise of dedicated energy professional that provide a tremendous amount of added value to the client.
