  13. An Advance Look at Some New Experimental Forecasting Products for the Power Industry

  14. Monthly System-Wide Energy Production Simulated by ColSim (Million MW-hr)

  15. PNW Daily Peak Load in January Regressed from a) Population Weighted TMAX b) Binary Weekday/Weekend Index Peak Hourly Load (Megawatts)

  16. CA Daily Peak Load in August Regressed from a) Population Weighted TMAX b) Binary Weekday/Weekend Index Peak Hourly Load (Megawatts)

  17. January Nino3.4 Anomaly vs PNW Avg NDJF Peak Electrical Load

  18. Experimental Energy Forecasts for the Western US In partnership with researchers at Scripps Institute of Oceanography we are in the process of producing long-range forecasts of energy demand over the western US based on long-range climate forecasts. One of potential applications of such forecasts, in conjunction with hydropower forecasts from the PNW, is improved energy transfer agreements between the PNW and CA that take into account the interannual variability of power supply and demand in the West.
