Abstract

Electricity customers who install solar panels often are paid the prevailing retail price for the electricity they generate. We show that this "net metering" policy typically is not optimal. A payment for distributed generation (w) that is below the retail price of electricity (r) will induce the welfare-maximizing level of distributed generation (DG) when centralized generation and DG produce similar (pollution) externalities. However, w can optimally exceed r when DG entails a substantial reduction in externalities. We demonstrate that the optimal DG policy varies considerably as prevailing production technologies change and that a restriction to net metering policies can both reduce aggregate welfare and have substantial distributional effects.
