RESEARCHDecember 29, 2008Grid can handle renewablesContrary to conventional wisdom, generating most of California's electricity from renewable sources will have a minimal impact on the grid.A simulation of electricity generation and transmission in California shows that replacing most of the natural gas with wind and solar power increases the load on transmission lines by an average of 0.5 percent. Under this scenario, 70 percent or more of California's electricity would be generated by renewable sources. The number of overloaded transmission lines would rise from 11 to 31 out of more than 5,000, suggesting that only a small portion of the transmission lines would need to be updated to accommodate a radical shift to renewable energy sources.
