Florida Power and Light Company (FPL) has commissioned the new $1.2bn Port Everglades next-generation clean energy centre (PEEC) near Fort Lauderdale in Broward County, Florida, US.
The 1,277MW power plant replaces the oil-fired power plant from 1960s, which was demolished by FPL in mid-2013.
Using 35% less fuel per megawatt-hour, the plant is expected to provide $400m in fuel and other savings to customers during its 30-year operation.
FPL president and CEO Eric Silagy said: "The Port Everglades Next Generation Clean Energy Center is yet another demonstration of our commitment to dramatically reducing our dependence on foreign oil, while at the same time, delivering clean, reliable and affordable energy for our customers.
"This facility is the equivalent of taking a car from the 1960s and replacing it with a hybrid, which is more fuel efficient and produces less emission.
"This energy centre is one more example of how the nearly 9,000 employees of FPL are working hard each and every day to ensure our customers benefit from electric bills that are among the lowest in the state and 30% below the national average."
The facility features three 250MW combustion turbine generators equipped with evaporative inlet cooling system, a 500MW steam turbine generator, three heat recovery steam generators (HRSG) with selective catalytic reduction reactors and three 149ft exhaust stacks.
Clean electricity generated at the plant will be enough to power approximately 260,000 homes and businesses.
The facility will contribute to the US Environmental Protection Agency's Clean Power Plan 2030 target.
The plan requires power plant owners to curb CO2 emissions by 32% from 2005 levels by 2030.
