On: Giant batteries and cheap solar power are shoving fossil fuels off the grid

Yes, but in some markets (via regulatory capture) retail power is SO expensive that rooftop solar is a great deal.

PG&E in California has tiered electricity costs of $0.28-$0.42/kwh

Meanwhile in other parts of the country, retail power could cost $0.06/kwh

bottom line: you are correct about utility scale power if there were a free market
