U.S. energy company Duke Energy Corp (DUK.N) said on Wednesday that it plans to triple its renewable power output to 23% by 2030 from about 7% now, as it continues to retire coal plants.
Combined with its six nuclear plants in the Carolinas, Duke said its carbon-free energy will be around 53% in 2030 and its move comes as U.S. consumers and federal and state governments seek more carbon-free power to stop climate change.
President Joe Biden's administration wants all U.S. power to come from non-carbon emitting sources such as renewables and nuclear by 2035.
Duke said it has wind and solar projects under construction in Florida, North Carolina, Oklahoma and Texas and will add 280 megawatts (MW) of pumped storage hydro capacity at its Bad Creek facility in South Carolina over the next three years.
The company, which has set goals of reaching at least a 50% carbon reduction by 2030 and net-zero carbon emissions by 2050, said its CO2 output was down more than 40% since 2005, mostly as a result of retiring coal generation.
It has retired 52 coal-fired units since 2010, representing about 7,000 MW of capacity, Duke said, adding that it plans to retire its remaining 30 or so coal units by 2048, representing about 16,000 MW of capacity.
Duke's electric utilities serve 7.9 million customers in North Carolina, South Carolina, Florida, Indiana, Ohio and Kentucky, and collectively own 51,000 MW of energy capacity. One megawatt can power about 1,000 U.S. homes.
Its natural gas unit serves 1.6 million customers in North Carolina, South Carolina, Tennessee, Ohio and Kentucky.
