Duke Energy Florida will increase its use of solar power and make improvements to the grid to enhance reliability, security and resilience in 2019. The company will invest in its Citrus Combined Cycle Natural Gas Plant and Hamilton Solar Power Plant. Duke Energy Florida broke ground on the Hamilton Solar Power Plant in Jasper, Fla., in July. The facility will generate 74.9 MWs of energy, which is enough to power more than 20,000 homes at peak production. It will be operational in December 2018.
