Energy Analyst Explains the Future of California’s Grid

California’s grid sees a daily midday surplus of solar and a rapid evening demand spike that raises prices.

Solar’s low marginal cost pushes conventional generators to cover a steep post-sunset ramp known as the duck curve.

Fast-start simple cycle gas turbines meet evening demand quickly but at lower efficiency, increasing evening prices.

Regional transmission limits between NP15 and SP15 can cause price divergence across the state.
