The California Independent System Operator Corp. (California ISO) has launched tools that enhance the visibility of renewable resources on the grid. The Solar Today Web graph depicts real-time data of solar energy being generated on the ISO wholesale power grid, which serves 80% of California.
Wind Today, the counterpart to Solar Today, shows real-time wind production on the grid. An overall snapshot of all renewable production for the previous day is also available on the California ISO website through the Renewables Watch. This tool provides a look back on production for wind, solar, biomass, biogas, geothermal and small hydroelectricity.
