Backtest

This endpoint provides a backtested energy production anomaly forecast (i.e., what our forecast would have been if queried on a specific day) for a particular latitude/longitude pair or a global forecast. Backtested forecasts are available from 2000 to 2024 on the 1st and 15th day of each month. The anomalies are based on the 1980-2010 baseline, with solar and wind power expressed as fractional units. Note that this endpoint does not include observed values. Weighted Degree Days is a composite variable of gas-weighted heating degree days (GW_HDDs) and population-weighted cooling degree days (PW_CDDs). GW_HDDs consider days below 65°F and PW_CDDs consider days above 65°F. The output is calculated for the contiguous United States (CONUS).
