Geothermal isn't competitive with PV and Wind. Neither is coal or nuclear. (Hydro can be used as storage so it's a bit more complicated, but still basically not competitive)
See any recent Lazard's Levelized Cost of Energy Analysis for full details.
For my specific claim about the cost of running just the steam part, look for the golden diamonds on the first chart here:
They mark the marginal cost of running a fully depreciated nuclear, coal or gas plant. Note how you can build new wind and PV for the same price as running the existing turbine based plants.
Those costs still include fuel, but don't include building the structures. So magical, fuel-less heat source powering steam is still going to struggle as PV and wind continue to drop in price.
