The California Independent System Operator Corporation’s (California ISO) announced AWS Truewind as winner of the year-long forecasting competition. Of the three companies that responded to the challenge, AWS Truewind provided the most accurate and cost effective information, showing a 20% improvement over current wind forecasting accuracy. Competing companies were required to submit 12-month forecasts for three of California’s wind markets, covering day-ahead and hour-ahead time frames. The competition was also intended to improve the power grid and integrate fluctuating wind power. With its increased accuracy, the forecasting data provided by the company will help the ISO better manage the growing market needs.
AWS Truewind has over 15,000 MW of operational wind projects in its forecasting portfolio and an experienced team of forecasters. The company will be use a custom (physics based) numerical weather-prediction model to provide forecasts for use in grid operations and serve as a foundation for the Participating Intermittent Resource Program which combines wind power into ISO markets.
“More than 3,000 MW of wind-generated power are connected to the grid right now,” says ISO Director of System Operations Debi LeVine. “Closely monitoring intermittent wind production keeps the grid in balance and the lights on. With wind resources expected to double over the next five years or so, accurate forecasting is imperative to maximize these new resources.”
