The electric power sector is once again evolving. A variety of distributed energy resources and improving computation, communication, and control technologies create an unprecedented degree of choice for electricity consumers, choices that are poorly guided by electricity rates and other incentives designed for a comparatively simpler era. These technologies also create new tools for regulated…

Responding to electricity shortfalls: Electricity-saving activities of households and firms in Japan after Fukushima
Japan has experienced a severe electricity shortfall since the Great East Japan Earthquake in March 2011 and the subsequent shutdown of nuclear power plants. Disruption to the supply-demand balance was especially severe in Tokyo and Tohoku in summer 2011, forcing the government to introduce mandatory rationing for large customers. Following intensive efforts, a reduction in…
Vehicle-to-grid Policy in South Africa: State-led v. Market-directed Approaches
The Vehicle-to-Grid (V2G) policy aim has been widely analyzed in policy planning literature but has not been explored for adaptation to African contexts. African countries enjoy immense renewable energy (RE) potential but currently experience minimal electric vehicle usage, since most drivers confront limited charging station access and thus range anxiety. One potential workaround surmounting this…
Who’s Responsible for Climate Change? New Evidence Based on Country-level Estimates of Climate Debt
In this paper we discuss the concept of climate debt, which measures the cumulative economic damages due to CO2 emissions. We find that the climate debt (estimated for 131 countries) is extremely large, equaling some $59 trillion over the 1959–2018 period. Climate debt is also substantial relative to other government liabilities; in the G-20, it…
Cheap Money, Geopolitics and Supernormal Backwardation of the WTI Forward Curve
Financial speculators frequently trade in the most liquid short-tenor contracts. We study repeating patterns of sharply steepening slopes in the WTI forward curve to investigate whether, after controlling for macroeconomic variables, physical market fundamentals, and basic arbitrage, calendar spread behavior is partly explained by speculation related to assessed geopolitical risk. We estimate WTI forward curve…
Incentive Regulation of Electricity and Gas Networks in the UK: From RIIO-1 to RIIO-2
The regulatory and operating context of energy networks is dynamic and constantly evolving. Achieving a multitude of economic, environmental, social and policy objectives is a challenging task for the sector regulators. In 2010, the UK energy regulator Ofgem replaced its approach to energy network price control and incentive regulation with a Revenue-Incentive-Innovation-Output (RIIO-1) model. This…
Different Cost Perspectives for Renewable Energy Support: Assessment of Technology-neutral and Discriminatory Auctions
Auctions are the prevalent instrument for promoting renewable energy sources worldwide, especially in the European Union and in Latin America. Auctions enable the controlled deployment of renewable energy sources while reducing costs. However, there are different views on relevant costs, auction targets, and their implications on the auction design. Here, the application of technology-neutral auctions…
Promoting Large and Closing Small in China’s Coal Power Sector 2006–2013: A CO2 Mitigation Assessment Based on a Vintage Structure
In the period 2006-2013, China’s power sector adopted a policy which aimed to add large scale units (larger than 600 MW) and decommission small, old (but still technically functioning) and inefficient power plants in order to accelerate energy saving and mitigate emissions. The early-retirement (ER) of nearly 90 GW of capacity and massive new coal…
Assessing the viability of Energy-Only Markets with 100% Renewables
Abstract – Efficient wholesale electricity markets should drive preference revealing bidding where generators offer the majority of their power at their short run marginal cost (SRMC). However, most renewables have very low SRMCs, which in a competitive market is likely to lead to an increasing proportion of low priced periods. Combined with concerns around the…
