Course Objectives

Wholesale power markets around the world are currently undergoing substantial changes in their structure and rules of operation. This process has come to be referred to as restructuring.

For example, twenty years ago most electricity in the U.S. was supplied by vertically integrated utilities operating under a regulatory compact whereby they agreed to provide an adequate supply of electricity for all users in return for receiving a fair rate of return on their capacity. In contrast, over 50% of generating capacity in the U.S. is now operating under a centrally administered wholesale power market in which electricity is priced in accordance with the location and timing of its injection into and withdrawal from the transmission grid.

Debates and controversy continue with regard to the exact form that restructured wholesale power markets should take. At the national level, regulatory agencies (such as the U.S. Federal Energy Regulatory Commission) are in the process of revising the entire regulatory framework within which these markets operate, with fiduciary responsibility for protecting against risks to national security. At the regional level, market administrators are devising and implementing new rules of operation in an attempt to ensure reliability as well as efficiency and fairness. At the level of participant traders, companies are developing new bid/offer strategies for the purchase and sale of energy and ancillary services in an attempt to enhance their net earnings while protecting against financial risks.

Some commentators continue to argue that this restructuring process has not produced the intended improvements in market efficiency while at the same time it has complicated the efforts of market administrators to ensure the reliability of market operations and the efforts of traders to protect themselves against financial risks. Given the extraordinary global financial crisis now taking place, it seems inevitable that calls will strengthen for a return to heavier regulation of wholesale power markets, possibly even for a return to administered cost-based pricing.

This power economics course will cover topics essential for understanding the current controversies surrounding the restructuring of wholesale power markets both here in the U.S. and abroad. Planned topics include: an historical overview of wholesale power market restructuring; microeconomic basics for power markets; strategic market behavior (game theory); optimization basics; wholesale power market operation over transmission grids; locational marginal pricing and optimal power flow; organization of restructured wholesale power markets (real-world examples); financial and operational risk management; system security and ancillary services; investment in new generation; financial transmission rights and transmission investment; and the potential for "green power."
