Türkiye Showcases Renewables Surge, but Leaves Coal Intact
On a windy hillside about an hour's drive northwest of Istanbul, the Catalca power plant was one of Türkiye's first large-scale wind farms and has been feeding electricity into the grid for 18 years. With an installed capacity of 93 megawatts, it generates 287 million kilowatt-hours of electricity a year, enough for around 115,000 households, said AFP. "By replacing electricity that would otherwise come from fossil fuel-fired power plants, this output avoids 185,936 tons of carbon emissions each year," operator Sanko Enerji says.
