Risks and Psychic Costs of Alternative Energy Sources for Generating Electricity

Miller B. Spangler

Year: 1981
Volume: Volume 2
Number: Number 1
DOI: 10.5547/ISSN0195-6574-EJ-Vol2-No1-3
View Abstract

According to public opinion polls, many people in the United States do not agree that there is truly an energy crisis. President Carter referred to it as an "invisible" crisis in the National Energy Plan of 1977.

Chapter 18 - Confronting Uncertainty: Contingency Planning for Decommissioning

Bruce Biewald and Stephen Bernow

Year: 1991
Volume: Volume 12
Number: Special Issue
DOI: 10.5547/ISSN0195-6574-EJ-Vol12-NoSI-18
View Abstract

Contingency factors are a standard ingredient in all types of estimated costs. The actual contingency figure used, however, is always open to question. Given the absence of large-scale decommissioning projects, the long future time reference, the history of early shutdowns, and possibility of accidents, there continues to be a substantial controversy regarding the contingency level that is most appropriate. In this chapter, Bruce Biewald and Stephen Bernow present a critical review of the matter of contingency factors, arguing that current common levels in the neighborhood of 25 percent are too low.

Evaluation of Risks for Electricity Generation Companies through Reconfiguration of Bidding Zones in Extended Central Western Europe

Caroline Deilen, Tim Felling, Robin Leisen, and Christoph Weber

Year: 2019
Volume: Volume 40
Number: The New Era of Energy Transition
DOI: 10.5547/01956574.40.SI1.cdei
View Abstract

In Central Western Europe, a reconfiguration of bidding zones for electricity is frequently discussed as a way to improve congestion management. The current EU guideline on Capacity Allocation and Congestion Management even envisages reviews of the bidding zone configuration (BZC) in regular intervals of three years. Such a change of BZCs gives rise to additional regulatory risk for generation companies. Their expected net present value depends on local prices, which are directly influenced by the BZC. The paper at hand develops a methodology to investigate the impact of this regulatory risk. Therefore the risk of bidding zone changes is modeled using a partly-meshed scenario tree. The risk factors reflected therein are uncertainties in grid developments, in combination with other risks such as changing coal and gas spreads, demand, or renewable infeed variations. Results are compared to the current BZC in Europe and to a nodal setup.
