GE’s Gas-Fired Plants Could Enable More Wind and Solar Power: The variability of solar power and wind power ca...

The variability of solar power and wind power can play havoc with the grid. In a political era where California and other states are mandating 20 percent or 33 percent or even 40 percent Renewable Portfolio Standards, the current system is not designed to deal with that level of variability , according to Jim Detmers, former COO of the California Independent Systems Operator (CAISO). "The system is not designed to accept that proportion of renewables." Increasing penetration of renewables like wind and solar actually require an increase in the amount of natural gas-fired backup. And natural gas plants are at their least efficient when they are are ramped up and down. Natural gas, despite its recent good press for being cleaner than coal and of domestic origin, is still a fossil fuel that pollutes the air when combusted and the water when extracted via fracking .
