The National Oceanic and Atmospheric Administration's (NOAA) Climate Predict Center (CPC) is forecasting a continuation of a major heat wave this week ending July 30th. Nearly every single state is predicted to experience higher than normal temperatures. In some states, such as Washington and Oregon, cooling degree days (CDDs) are forecast to be more than double their normal levels. However, in the two states that burn the most natural gas at power plants, Texas and Florida, the heightened temperatures will be more muted.
Based on NOAA's state-by-state cooling degree day forecast, weighted by natural gas-weighted electricity production, I estimate that CDDs will be 30% higher than normal and 12% higher than in the same week last year.
For the year-to-date, cumulative CDDs are 22% higher than normal but the same as than during the year-to-date in 2015. [Continue reading]
