Duke Energy has filed an update to its 2022 state-mandated carbon-reduction plan with the public utility commissions of North and South Carolina, proposing the deployment of small modular reactors at the Belews Creek coal plant in Stokes County, N.C., which is slated for retirement next decade. A similar system would be added at a second site yet to be determined for a total of 600 MW of advanced nuclear. (Both the advanced reactor production tax credit and investment tax credit included in last year’s Inflation Reduction Act offer a 10 percent bonus for facilities sited in certain energy communities, including those with retiring coal plants.)

Australia’s two large lithium-ion storage batteries are getting attention for all the wrong reasons. Hornsdale Power Reserve, a 150-MW battery collocated with a wind farm in South Australia, is being charged in federal court with failing to deliver on promises to respond to grid demands, and of being technically unable to deliver under the terms it was being paid to meet. Proceedings were filed September 22, just before the testing of a second Tesla-manufactured “Big Battery” resumed after a two-month delay following a fire in July.
