Energy Policy and Planning Group
UHERO fellows conduct research to evaluate impacts of past and prospective energy-related policies, and engage with policymakers and stakeholders on contemporary and emerging energy issues, such as natural hazard resilience and associated clean air goals, energy efficiency, electric vehicles, and carbon taxes.
Effects of alternative pricing structures on electricity consumption and payments in the commercial and industrial sector
Abstract: We investigate the distributional and welfare impacts when commercial and industrial (C&I) electricity end users face a dynamic pricing structure as opposed to a constant volumetric price with demand charge on individual users’ peak usage. While demand charge does not necessarily reduce the system-wide peak, it often constitutes a large share of C&I users’ […]
Read MoreA Comparison of State-Level Carbon Reduction Strategies: A Case Study of Hawai‘i
Abstract: State-level electricity standards are proliferating and becoming more ambitious, with numerous US states adopting a Renewable Portfolio Standard (RPS) and a small but increasing number of states participating in carbon pricing programs. The State of Hawai‘i has an ambitious RPS that requires 100% electricity generation through renewable sources by 2045. This study uses a […]
Read MoreReal-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 MoreEconomic and GHG impacts of a US state-level carbon tax: the case of Hawai’i
A new paper by a team from UHERO published in Climate Policy finds that a carbon tax for Hawai‘i set at the federal social cost of carbon would reduce cumulative GHG emissions by 10% relative to the baseline from 2025 to 2045. They find that when carbon tax revenues are paid as equal-share dividends to Hawai‘i […]
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 MoreAre We Hitting Our Targets? A Look at Hawai‘i’s GHG Emissions
By Makena Coffman, Maja Schjervheim, and Paul Bernstein Over the past three years, the State of Hawai‘i Department of Health has released a Hawai‘i Greenhouse Gas Emissions Report. This year’s report added an inventory for 2017, as well as projections through 2030 based on existing policies and trends. UHERO collaborated with ICF on this project and […]
Read MoreIs a Carbon Tax Viable for a Small Island Economy?
By Maja Schjervheim, Paul Bernstein, Sumner La Croix, Makena Coffman, and Sherilyn Hayashida For the third year in a row, a carbon tax bill fizzled out at the Hawaiʻi State Legislature. Perhaps it was the difficult timing of introducing a new tax in the wake of a pandemic. Perhaps it was due to qualms regarding […]
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 […]
