Using load resources to meet ancillary service requirements in the ERCOT market: A case study

The presentation will show a history of past deployments over the past 4 years. For selected events, we will discuss curtailment duration and the reason that triggered these deployments. A specific event that we will discuss occurred in February 2008 when ERCOT experienced a dramatic increase in load combined with a large drop in wind generation, which led to a system-wide deployment of Load Resources providing Responsive Reserves. We plan to conclude the presentation by discussing some of the new challenges and opportunities that Load Resources are facing as ERCOT moves from a Zonal Market Structure to a Nodal Market Structure.
