Congestion in the Texas Panhandle: LCG Consulting investigates ERCOT’s rapid wind development and Lubbock Power & Light joining the ERCOT grid


LCG, May 10, 2016-- LCG Consulting has released a new study of wind energy development in the Panhandle Renewable Energy Zone, or PREZ, of Texas, where ERCOT has proposed significant changes in the infrastructure to enable sustained wind development and ensure stability of the grid.

The Panhandle region of ERCOT has seen unprecedented growth in wind generation, a trend which is expected to continue in coming years. At the same time, Lubbock Power & Light is planning to leave the Southwest Power Pool, SPP, and join ERCOT in 2019. ERCOT has implemented a Panhandle Export Stability Interface limit in response to increasing regional wind capacity that may cause voltage instability.

LCG’s study, ERCOT Panhandle Renewable Energy Zone and LP&L Integration, looks at how these changes affect power flow and locational marginal prices under various scenarios. It outlines infrastructure challenges, current developments in wind curtailment due to Panhandle congestion, and it provides an outlook for wind generation in the region. Analysis was conducted using the UPLAN Network Power Model which replicates ERCOT ISO protocols and market procedures. Read Executive Summary of the Report.

LCG Consulting has been modeling the electricity grid for more than 30 years and has conducted energy studies in Asia, Europe, Africa, and the Middle East, as well across the United States and Canada.
