Electric Power Monthly!
February edition, for capacity changes and generation December 2019, so full year 2019 results are in!
Coal capacity dropped 432MW in December 2019, and 13,544.2MW in total in 2019 to end at 229,241.4MW. Forecast capacity reductions increased. Last month, the 12 month net capacity change forecast was -5,175.9MW. This month the forecast decreased by 1,399.9MW to -6,143.8MW. So, a much smaller decrease than 2019, but the capacity reductions continue.
Coal's rolling 12 month share dropped another 0.59% to 23.26% for the whole of 2019, a drop of 4.00% from 2018. Coal was 48.21% of generation in 2008. December 2019 generation was 72.6TWh compared to 96.8TWh in 2018, and for the whole year was 966.1TWh compared to 1,146.0TWh for 2018.
Coal's capacity factor for December 2019 (43.2%) was much lower than for December 2019 (55.9%), again continuing the trending of falling capacity factors. The rolling 12 month average and 2019 capacity factor was 47.5%, compared with 53.6% 12 months ago.
Given the large reductions in coal generation capacity during 2019, and continuing capacity factor reduction despite the closures, we should continue to see a reduction in generation in 2020. It's extraordinary to think that at the current rate of decline, it's possible that by the end of 2020 coal generation will fall below that of nuclear.
Nuclear capacity was unchanged in December 2019 and ended 2019 at 98,070.2MW. Planned 12 month capacity changes decreased by 601.4MW to -1,597.5MW, so the gradual decrease continues but at a much slower pace than coal.
Nuclear generation in December was up compared to last year (73.1TWh v 71.7TWh), but for 2019 was up on very slightly, at 809.4TWh v 807.1TWh.
Unlike coal, nuclear capacity factors are stable or rising. Rolling capacity factor is 93.4%, compared to 92.5% 12 months ago. December 2019's capacity factor was 100.1%. A busy month.
