Executive Summary WMWG had an extremely full agenda. ERCOT (Nitika Mago) presented more detail on the 2022 AS Methodology and also presented analysis on what an ERCOT duck curve might look like in a few years. ERCOT (Carl Raisch) also presented on what price responsive behavior they’ve seen in load resources (they haven’t seen much). …
Executive Summary The first real meeting of the new independent Board of Directors.
