We consider a supply function model of a poolco electricity market where demand varies significantly over a time horizon such as a day and also has a small responsiveness to price. Although there are equilibria yielding prices at peak that are close to Cournot prices, it is known that the wider...

We characterize the cost function for electric power transmission. It is complex and non-linear, exhibiting scale economies over its range. The social planning problem for network transmission expansion is illustrated with a simple numerical example. The regulatory problem for joint generation...

We consider a supply function equilibrium (SFE) model of interaction in an electricity market. We assume a linear demand function and consider a competitive fringe and several strategic players having capacity limits and affine marginal costs. The choice of SFE over Cournot equilibrium and other...

The fundamental objective of most regulatory mechanisms is to expand output at a sufficiently low cost to consumers. Many useable mechanisms, such as Loeb and Magat's, require detailed demand information and substantial profit recapture by the regulator in order to achieve this objective. We...
