Summary
Korea District Heating Corp. (KDHC) President Kim Kyung-won said, “Eco-friendly combined cycle power plants need to serve as a ‘bridge’ along the road of an energy paradigm shift from nuclear power and coal-fired plants to new and renewable energies.” KDHC President Kim was busy preaching the strengths of combined cycle power ahead of the commissioning of the 800MW-class Dongtan Combined Cycle Power Plant, the largest one of its kind in Korea, on Dec. 22.
Combined cycle power (community energy) not only generates electricity by using liquefied natural gas (LNG) in principle, but also produces steam for heating by using exhaust heat from power generation. Combined cycle power plants have higher energy efficiency and emit less greenhouse gas. Combined power units have an efficiency rate of more than 80 percent, compared to other plants for power generation, which stand at less than 50 percent.
“Expanding new and renewable energies is not easy to come by in a short period of time due to such limitations as a lack of sites, and their power supply stability is getting lower,” he said in a recent interview. As the combined cycle power plant serves as an emergency electricity to cope with an unstable power supply of new and renewable energies, the community energy will be a bridge in an era of energy shift, President Kim said.
