The utility also has to be prepared to provide you with the power that you aren't using (if there's a solar eclipse or something). The marginal cost of power generation is very low, so you save them almost nothing by not using the power.
- ethbro 11y agoThe marginal cost of average power is very low. At least for solar in the south (air conditioning), the marginal cost of peak daytime power is much less so. Remember that capacity is sized for peak utilization: the gap between average load and peak is load is extremely expensive, as it's by definition low-utilization compared to base load generation.
