happyinmotion@kravietz @cstross The nuance is that cost of storage/LFSOE depends upon firmness of rest of the grid at a all timescales. That depends on dispatchable generation, how uncorrelated renewables are, and what imports are possible. There's no single number - grids are all unique and so are their storage costs
NZ has run-of-river hydro so we already have more hour-to-month storage for free than we need. Our problem is dry winters. Our cheapest solution is over-building wind & PV & geothermal. 1/3
