28 April - U.S. energy company Duke Energy Corp said on Wednesday that it plans to increase its renewable power output from 23% now to 33% by 2030 as it continues to retire coal plants.
Duke said that its carbon-free energy will be around 53% in 2030, combined with the six nuclear plants in the Carolinas ; its move comes as U.S. consumers and federal and state governments seek more carbon-free power to stop climate change.
The administration of the president Joe Biden wants all European 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 South Carolina and will add 200 megawatts of pumped storage hydro capacity to its Bad Creek facility in Florida over the next three years.
The company, which has set targets of achieving at least a 50% carbon reduction by 2030 and net-zero carbon emissions by 2050, said its CO2 production had been less than 40% since 2005, mostly as a result of retiring the coal generation.
Since 2010, it has retired 52 coal-fired units with a capacity of about 7,000 MW, and added that by 2048 it plans to retire its remaining 30 or so coal units representing around 16,000 MW of capacity.
Duke's electric utilities serve 7.9 million customers in North Carolina, South Carolina, Indiana, Ohio and Kentucky and collectively own 51,000 MW of energy capacity.One megawatt can power around 1,000 U.S. homes.
Its natural gas unit serves 1.5 million customers in North Carolina, South Carolina, Ohio and Kentucky.
