How electricity markets and storage economics actually work: why the price mechanism can push wholesale power to zero, why a plant's nameplate rating overstates what it delivers, and the breakeven math a battery has to clear before arbitrage is worth doing.

Capacity factor converts a plant’s nameplate rating into the energy it actually produces over time. Read the first noteThen keep going
The reading order
Each note builds on the question before it, without hiding the rest of the route.
- 02 Solar can push the electricity price to zero — and that's a problem In a marginal-price market, enough zero-cost supply drives the clearing price down to the lowest offer in the stack.
- 03 1.18× is the arbitrage floor a battery actually needs A battery breaks even on energy only when the high price exceeds the low price divided by efficiency.
