ERCOT Wind Expansion: Impact on Energy and Ancillary Service Markets
LCG, October 05, 2016--LCG Consulting has released its latest report Market Effects of Wind Penetration in ERCOT: How Wind Will Change the Future of Energy and Ancillary Service Prices. In this study, LCG investigates the system-wide impacts on the ERCOT market of three levels of wind capacity expansion in the year 2021, with particular emphasis on energy and ancillary service prices.
The nodal market simulations for this study were performed at the five-minute dispatch level using LCG’s UPLAN Network Power Model (NPM) and PLATO-ERCOT data model to capture the intermittent nature of renewable energy. UPLAN is a fully integrated model; that is the dispatch, transmission load flow, contingencies, curtailments, and ancillary services deployment are all resolved simultaneously.
The unprecedented growth of wind power in recent years has had a profound impact on the ERCOT market. With growth expected to continue, LCG’s report offers market participants a view of what can be expected as wind capacity continues to expand. Read Executive Summary of the report.
