Kind of whistling into the wind. Fact is this will happen much faster as homes, buildings, businesses just make, store their own will cut demand to Duke greatly.
Building any FF plant now is just dumb as will be obsolete before it even gets built.
As we come out of another Repub recession made even worse by incompetence on covid RE and EVs with V2G will be favored in the stimulus because the best easiest way to get new jobs that makes the thing we need in the future.
And they also put the power to the people which will likely end with bankruptcy for Duke, many other IOUs as loads become generators, cutting grid demand and competing directly with the utility with lower costs than FF utility power..

" Duke has shifted the $2 billion it planned to invest in the canceled Atlantic Coast Pipeline project to more clean energy and grid investments to reach its goal to double its share of renewables from 8 gigawatts to 16 GW by 2025.

This move to install GW of generation seems to have an 'installed price point' of $250/kWh. A circling of well established electric utilities are becoming more prominent as more and more energy companies build generation infrastructure and look for more assets to put into their energy portfolios. NextEra may overextend themselves or become the new Energy electric utility model of the future.

NextEra has 2 sides and while doing well on the green generation side, they fight like hell to keep FFs, utility monopoly fighting DR solar, etc in Florida under FPL.
I expect the same if they buy Duke which also has a big utility in west Florida making about 50% of the state under FPL/NextEra if they merge.
So as a model, no thanks.
