HB 2305 requires ERCOT to collect and analyze data on customer responses to conservation appeals during periods of high electricity demand. The bill mandates that ERCOT gather information on energy usage reductions at the ZIP code level when conservation appeals are issued. It authorizes ERCOT to request necessary data from electric cooperatives, municipally owned utilities, retail electric providers, and transmission and distribution utilities, while prohibiting the disclosure of individual customer usage data or personal information. ERCOT must publish quarterly analyses on its website and submit an annual report to the legislature summarizing customer conservation behavior​.
