Document Type
NOE - Notice of Exemption
Document Description
The purpose of this Agreement is to fund the development of improved forecasting of solar irradiance in California, with a particular focus on fog and stratus conditions, through targeted deployment of data collection instrumentation. The improved forecasts will be integrated into operational tools for use by the California Independent System Operator (CAISO) and utilities. This Agreement will utilize a targeted instrumentation network, consisting of existing and new sensors, to improve the models used for forecasting fog and stratus conditions. The Recipient will design and deploy this network with the aim of improving the forecast that are most important to CAISO and utility operations. The equipment to be installed in the five existing monitoring sites is: ceilometers, pyranometers for solar irradiance, SODARs, and surface meteorological stations. The beneficiaries of this project will include utility ratepayers.
