|June 2018||Variable Pricing and the Cost of Renewable Energy|
with Matthias Fripp, Michael J. Roberts: w24712
On a levelized-cost basis, solar and wind power generation are now competitive with fossil fuels. But supply of these renewable resources is variable and intermittent, unlike traditional power plants. As a result, the cost of using flat retail pricing instead of dynamic, marginal-cost pricing—long advocated by economists—will grow. We evaluate the potential gains from dynamic pricing in high-renewable systems using a novel model of power supply and demand in Hawai’i. The model breaks new ground in integrating investment in generation and storage capacity with chronological operation of the system, including an account of reserves, a demand system with different interhour elasticities for different uses, and substitution between power and other goods and services. The model is open source a...
