We evaluate the cost-effectiveness of various policy options and infrastructure investment proposals to improve the security of gas supply in Bulgaria, one of the most gas insecure countries in the European Union. We do this by computing ‘security of supply cost curve’ for different gas...

On both sides of the Atlantic the regulation of gas transmission networks has undergone major changes since the early 1990’s. Whereas in the US the long-standing regime of cost-plus regulation was complemented by increasing pipe-to-pipe competition, most European countries moved towards...

This paper attempts to verify whether we are moving towards a new paradigm of the network energy industry (electricity and natural gas), based on a wide decentralisation of the energy supply. We do this by comparing the social benefits of decentralised and centralised models, simulating...

In the last two decades many major regulatory issues in Florida have been resolved by means of stipulated settlements between the utilities and interested parties, notably the Office of Public Counsel, instead of by the traditional method of hearings and litigation before the Public Services...

Relatively little is known about the practice of settlement rather than litigation in US utility regulation, or about the activities of consumer advocates. This paper presents evidence from Florida. During 1976-2002, over 30 per cent of earnings reviews were settled by stipulations involving the...

The Federal Power Commission pioneered the use of negotiated settlements in the early 1960s as a means of coping with an increased workload and backlog. Legal scholars have emphasized the importance of settlements in coping with the regulatory load, and in saving time and money, albeit with some...

Interstate gas pipelines and their customers presently settle about 90% of the rate cases set for hearing before the Federal Energy Regulatory Commission (FERC). In recent years, the median time for negotiating settlements and having them approved is about 11 months, compared to several years to...

This paper studies the impact of divestiture on the efficiency and costs of electric utilities. The empirical literature shows that there exist economies of scope for electric utilities and that divestiture decreases distribution efficiency but increases generation efficiency. This paper is to...

The Great East Japan earthquake and tsunami on March 11th 2011 caused mass destruction, significant loss-of-life and a large displacement of people. It also placed significant strain of Japan’s electricity-generating infrastructure. There was a significant reduction in capacity due to the...

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...
