Real-Time Pricing and the Cost of Clean Power
Solar and wind power are now cheaper than fossil fuels but are intermittent. The extra supply-side variability implies growing benefits of using real-time retail pricing (RTP). We evaluate the potential gains of RTP using a model that jointly solves investment, supply, storage, and demand to obtain a chronologically detailed dynamic equilibrium for the island of […]
Read MoreAre We Building Too Much Natural Gas Pipeline? A comparison of actual US expansion of pipeline to an optimized plan of the interstate network
Interstate natural gas transmission and storage infrastructure is facilitated using regulated, private transactions. Pipeline companies obtain long-term contracts from producers and wholesale purchasers, typically local distribution companies (LDCs). In the past, the Federal Energy Regulatory Commission (FERC) accepted these counterparty contracts as sufficient justification of need. Typically the LDCs are themselves regulated firms, which sometimes […]
Read MoreUsing Temperature Sensitivity to Estimate Shiftable Electricity Demand Implications for power system investments and climate change
Growth of intermittent natural hazard resilience make it increasingly difficult to manage electricity demand variability. Transmission and centralized storage technologies can help, but are costly. An alternative to centralized storage is to make better use of shiftable demand, but it is unclear how much shiftable demand exists. A significant share of electricity demand is used […]
Read MoreImplications of a “Green Tariff” for the University of Hawai‘i, Hawaiian Electric Company, and other Customers
In June 2015 the State passed a law setting a goal for the University of Hawai‘i (UH) to produce as much renewable energy as the total energy it consumes; that is, to become net-zero. The great bulk of the University’s energy use occurs on the Mānoa campus, which has the most students and by far […]
Read MoreVariable Pricing and the Cost of Renewable Energy
On a levelized-cost basis, solar and wind power generation are now competitive with fossil fuels, and still falling. 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 supported by economists–will grow. We evaluate the potential […]
Read MoreEffect of Electric Vehicles on Design, Operation and Cost of a 100% Renewable Power System
This report outlines the effect that electric vehicles could have on the cost of transport and electricity production in the context of a 100% renewable power system (RPS). Results presented here were produced using the SWITCH power system planning model, configured to choose a least-cost plan to achieve 100% renewable power on Oahu by 2045, […]
