Efficiency and productivity analysis is a central concept in incentive-based regulation of network utilities. However, the efficiency measures obtained from benchmarking predominantly reflect short term performance and hence, provide only a snapshot of the firm's path towards its long run...

Investment in electricity networks, as regulated natural monopolies, is among the highest regulatory and energy policy priorities. Given the large scale of required investments in the coming years, impelled by the need for decarbonising the electricity sector, identifying investment drivers of...

Following the liberalisation of the electricity industry since the early 1990s, many sector regulators have recognised the potential for cost efficiency improvement in the networks through incentive regulation aided by benchmarking and productivity analysis. This approach has often resulted in...

We summarises the main factors that differentiate impacts of the EU ETS on profitability and market share. By examining sampling a range of sectors, we present some simple metrics and indicators to help judge the nature of potential impacts. We also consider briefly the mitigation response to...

In electricity, “downstream” CO2 regulation requires retail suppliers to buy energy from a mix of sources so that their weighted emissions satisfy a standard. It has been argued that such “load-based” regulation would solve emissions leakage, cost consumers less, and provide more...

The paper1 discusses the determination of the social cost of carbon (SCC) using the PAGE2002 model used in the Stern Review. The SCC depends sensitively on assumptions about future economic development, the range and likelihood of economic and social damage arising from climate change at future...

The European Directive on the EU ETS allows governments to auction up to 10% of the allowances issued in Phase II 2008-2012, without constraints specified thereafter. This paper reviews and extends the long-standing debate about auctioning, in which economists have generally supported and...

The framework proposed by Ofgem, OFT and CMA invokes a well-functioning market, but the Competition Commission has not always used such a concept, and when it has done so it has been problematic. Here, the well-functioning market is Ofgem's vision of a successful market, not anchored in any...

The incentive regulation of costs related to physical and cyber security in electricity networks is an important but relatively unexplored and ambiguous issue. These costs can be part of a cost efficiency benchmarking or alternatively dealt separately. This paper discusses the issues and...

This study explores and quantifies the benefits of connecting more distributed generation (with and without the use of smart connections) across different parties (Distribution Network Operators, wider society and generators). Different connection scenarios are proposed (with partial and full...
