This is not how markets work. Imagine you have your own factory and your own gas turbine powering that factory. One day, somebody builds a grid and you have the option to buy from it at any time. Sometimes, but not all the time, there’s so much wind and solar that the market price is cheaper than running your gas turbine. You save money by turning your turbine down and buying from the market. You are still free to run your turbine at 100%, but it would cost you *more money* to do so. The grid also works like this. We dispatch the cheapest sources first, just like you would if you owned them all. Using cheaper sources of power when they’re available *does not increase costs.* The *unit cost* of electricity from your gas turbine may go up because you capitalize the expense over fewer units, but the *total cost* goes — *down.*
