  • California Boosts Grid Flexibility with Another Fast-Start Plant

    California’s drive to add flexibility to its grid in response to expanding renewable generation took another step forward in September as NRG Energy commissioned two new fast-start units at its El Segundo Energy Center near Los Angeles. The two units, with a combined 550 MW capacity, represent the second Siemens Flex-Plant to go into commercial […]

  • How Top Gun Eased Wind, Solar Integration

    As variable generation from wind and solar power increases and peak loads grow and become more volatile, the U.S. electric grid will rely more and more on gas-fired power to maintain system flexibility. Often at the core of these gas-fired power plants are aeroderivative turbines, whose fast-start and cycling capabilities allow for frequent on-again, off-again […]
