May 19, 2011, AUSTIN – The Board of Directors for the Electric Reliability Council of Texas (ERCOT), the state grid operator and manager of the wholesale electric market, approved a temporary price cap revision for the Valley area and seven protocol changes at Tuesday’s monthly meeting.
After a lengthy discussion, the board approved an interim methodology for setting the maximum shadow price on the Valley Import Constraint, effective May 25. The board’s resolution also directed the Technical Advisory Committee to report back to the board on a recommendation for a holistic methodology for setting appropriate shadow price caps for constraints not resolvable by Security Constrained Economic Dispatch (SCED), and a recommendation for addressing gaps between operations and planning processes to indentify constraints not resolvable by SCED.
Board members approved four Nodal Protocol Revision Requests (NPRRs), one System Change Request (SCR), one Nodal Operating Guide Revision Request (NOGRR), and one Planning Guide Revision Request (PGRR). The changes approved included:
- NPRR 306 – Revisions to Protected Information to Include Black Start Documents Considered Critical Energy Infrastructure Information;
- NPRR 310 – Expand Output Schedule Acceptable Range to Include High Sustained Limit and Low Sustained Limit;
- NPRR 350 – Change to the Security Classification of the System Ancillary Service Capacity Monitor Dashboard;
- NPRR 352 – Real-Time High Sustained Limit Telemetry for Wind-powered Generation Resources;

- NOGRR 054 – Change in Facilitator for the Annual Operations Training Seminar;
- PGRR 004 – New Planning Guide Section 2, Synchronization with NPRR 291, Reduce the Comment Period for NPRRs and SCRs.

Paul Hudson, founder and principal of Stratus Energy and former chair of the Public Utility Commission of Texas, will be coordinating stakeholder involvement in ERCOT''s long-term transmission planning study, ERCOT announced this week.
The study is a three-year effort, funded in part by the U.S. Department of Energy (DOE), to evaluate the long-term transmission needs of the ERCOT region. Hudson, who will be engaged on a part-time contract basis funded by DOE, will be responsible for increasing the overall participation of stakeholders in the study process.
Hudson currently works with a variety of energy-related interests, providing strategic guidance and assessment to a range of cleantech, renewable and power industry efforts. Prior to entering private practice, Hudson served as commissioner and chair on the Public Utility Commission from August 2003 to September 2008. He previously served in other state policy roles including director of policy to Governor Rick Perry.
“We are pleased that Paul has agreed to coordinate the Long-Term Study Task Force and other stakeholder outreach activities in the DOE study process. His background makes him uniquely qualified to lead this important effort,” said Warren Lasher, manager of long-term planning for ERCOT. “Stakeholders participating in the long-term study are not only helping us identify the issues that will affect the long-term energy needs of Texas, but are also helping us develop a framework to meet the future planning needs of the ERCOT system.”
