In South Australia rapid expansion of grid-connected and distributed renewable generation has contributed to the closure of coal-fired electricity production and placed greater reliance on the remaining fossil-based generation and imports on meeting demand when South Australian renewable production is low. Concentrated wholesale markets and gas scarcity now explain higher wholesale electricity prices and lower…

Comparing Interstate Regulation and Investment in US Gas and Electric Transmission
The interstate electric and natural gas sectors in the United States share some common regulatory elements, although the simpler economics of network expansion in gas pipelines allow the industry to operate on a contract-based framework that would be highly inefficient in electric transmission. The strong incentives for new pipeline development have allowed new gas pipeline…
The Importance of Penalties and Pre-qualifications: A Model-based Assessment of the UK Renewables Auction Scheme
This paper assesses the multi-technology auctions for Contracts for Difference (CfDs) in the UK, with a special focus on how pre-qualifications and penalties affect bidders’ behaviour, risk aversion and bidding strategies and thus the auction outcomes in terms of prices and project implementation probability. The auctions are modelled to closely represent the auction design foreseen…

The Coupled Cycles of Geopolitics and Oil Prices
We analyze the coupled cycles of Middle-East geopolitical violence and oil prices. Building on earlier work that shows that low oil prices are regularly followed by geopolitical strife, and that the latter is usually followed by higher oil prices, due to actual or feared disruption in oil supply, we focus in this paper on one…
Carbon Pricing and Cross-Border Electricity Trading for Climate Change Mitigation in South Asia
South Asia’s electricity supply system is quite carbon-intensive, particularly due to extensive use of coal. Under “business as usual,” that situation is expected to continue for several decades. Using an electricity system planning model, this study investigates two complementary strategies to reduce CO2 emission intensity of the power sector in South Asia: carbon pricing, and…
An Extended Analysis on the Remuneration of Capacity under Scarcity Conditions
This paper extends a recent analysis which investigated the impact of scarcity adders produced by operating reserve demand curves on the financial viability of generation units in the Belgian market. Our paper is inspired by practical considerations related to the implementation of the mechanism in European electricity markets. We are specifically interested in: (i) the…
