Project Summary

The University of California, San Diego project focused on providing utilities, the solar industry and utility customers with electricity system planning, design and operation modeling tools with the ability to accurately assess and forecast energy output and account for distributed PV systems. This was done using the existing infrastructure and databases through the state to improve the temporal and spatial resolution of solar maps and resource tools. It's become increasingly important to predict and balance the impact of transient cloudiness (or intermittency) through geographic dispersion of sites as state moves toward performance based incentives. The model outputs were integration into utility forecasting tools and transmission and distribution models based upon the needs of California Independent System Operators and the utilities in the state.
