The California Independent System Operator Corp. (California ISO) has opened access to renewable power data via two Web-based tools – Today's Wind and Renewables Watch – that make green energy production transparent on an hourly and daily basis.
Today's Wind provides an hour-by-hour chart showing the output of California's major wind resource areas. It breaks down wind's contribution to the grid at any given hour in the day.
Renewables Watch is a look back at the total renewable power output from the day before. It captures the megawatts produced from wind, solar, biomass, biogas, geothermal and small hydroelectricity. The daily report offers a comprehensive look at the diverse resource mix in California and charts output over the course of the day, hour-by-hour, California ISO explains.
