Requiring more power plants doesn’t mean that power will be more expensive. Power will only be more expensive if we get more demand and less supply. If supply (power plants) increases linearly with demand there won’t be a price difference.

Power doesn't work as simply as that.

Example: as a regulated utility it will often cost more per unit if underused vs optimal generating supply (which has already been passed through into rates)

Additionally, the generating source heavily influences ultimate cost.
