Generators supplying electricity markets are subject to volatile input and output prices and uncertain fuel availability. We show that a price-taking generator will generate only when the output price exceeds its operational marginal cost by the value of the option to delay the use of stored...

Real option analysis typically assumes that projects are continuously evaluated and launched at precisely the time determined to be optimal, but real world projects cannot be managed in this way because of the costs of formally evaluating an investment opportunity. This paper shows that...

Generators supplying electricity markets are subject to volatile input and output prices and uncertain fuel availability. Price-risk may be hedged to a considerable extent but fuel-risk - water flows in the case of hydro and gas availability in the case of thermal plants - may not be. We show...

Cooperatives and mutual organisational forms arise for reasons which include contracting problems between parties. Economic literature suggests a variety of allocated inefficiencies implied by these forms that largely have their origins in poor investment decisions. We demonstrate that a...
