Existing power stations that are paid off have an advantage considering cost of capital (nuclear and pumped hydro), but that advantage eventually theta decays when maintenance costs exceed new build costs. France is experiencing this now with its aging nuclear fleet [1]. Running the math on Tesla's calculator [2], a quarter worth of annual production (10GWh) runs $3,798,849,522 (~$3.8B). That includes installation (per Tesla). Can new pumped hydro be built cheaper than that? For sure, keep existing low carbon generation or storage in service as long as commercially reasonable.
