It's been reported that Coal has a statistical mean averaged coefficient of utilization of 0.72,which means that in any given year,a coal-fired power plant will only be online 262-days of the year,and will have to rely on 100% power from 'elsewhere' to cover for it over the duration.

One promise of deepwater,offshore wind,is less variability in production.
During 'dog-days',perhaps solar,or grid battery storage can take up some of the slack.
