Abstract
A retrospective diagnostic analysis on the behavior of temperature based proxies of peak heating and cooling demand across the Texas Interconnection is presented. Trends in annual maximum heating and cooling degree days are assessed across Texas to understand the role climate may have played in changing the peak demand characteristics. Persistent heating and cooling requirements can stress the system. Consequently, we assess trends for the annual maxima in heating/cooling degree hours over durations ranging from 6 hrs to 14 days. Statistically significant increasing trends are found in the annual maximum cooling demands for all durations. The heating demand trends are not statistically significant across the spatial domain, but tend to decrease. Finally, implications for human hazard safety, grid management and planning are discussed.
