Welcome!

We partner with local electric utilities to create high-resolution weather and power forecasts for the Southwest United States. We serve operational forecasts for more than 3 GW of renewable power generation (solar and wind) across Arizona and New Mexico.
Accurate forecasts reduce the uncertainty utilities face with these variable generation resources and ultimately enable the integration of more renewable power onto the grid. Our forecasts facilitate utility participation in the Western Energy Imbalance market and are used by wholesale energy schedulers, grid operators, day-ahead energy marketers, and real-time traders.

An important aspect of our forecasts is that they represent a range of outcomes derived from multiple runs of our numerical weather prediction model with staggered start times, rather than a single number. We run a customized high-resolution (1.8km) WRF ensemble forecast system that produces these models. The spread of the range of outcomes provides an estimate of the uncertainty of the forecast, which is crucial to predicting power generation from variable energy resources. With the ensemble of forecasts, users can improve energy market trading strategies, schedule more efficient generators, reduce costs, defer maintenance, and optimize the use of battery energy storage systems.
