Stoft was one of the first to rigorously apply the Herfindahl-Hirschman Index (HHI) to electricity. He demonstrates why a generator in a constrained zone can act like a monopolist, even if there are thousands of competitors elsewhere.
For nearly a century, the power grid was managed by monopolies where engineers treated everything as a giant optimization problem. When competition was introduced, this single control point vanished, and a new conflict emerged: the physics of electricity (which doesn't follow standard commodity rules) began to clash with the economics of the free market. جامعة ديالى The Five-Act Narrative
Generally, no. The book is still under copyright by IEEE/Wiley. While Stoft himself has been sympathetic to students (he once hosted drafts on his personal site), the final published PDF is a commercial product.

Note to readers: As of 2025, Steven Stoft has not released an official third edition. The 2002 first edition remains the definitive source. Stoft was one of the first to rigorously
For those interested in learning more about power system economics, we recommend the following:
Analyzes the design of day-ahead and real-time markets, comparing different structures like power pools and bilateral power exchanges. When competition was introduced, this single control point
Introduces essential economic and engineering concepts, including auction design and how marginal-cost pricing is intended to cover fixed costs.
Ethan is baffled. The market works perfectly every five minutes. Yet, the long-term story fails. He re-reads Stoft’s famous chapter on The narrative is tragic: Energy markets only pay for marginal energy (fuel). They do not pay for capacity —the fixed cost of being ready to run. In a pure energy market, when supply is plentiful, prices are low; generators make no money to cover their capital costs. But when supply is scarce, prices should spike to $10,000/MWh to pay for that scarcity. Politicians cap prices to avoid "spikes." Therefore, the money to build new plants simply vanishes from the market.
Here is a detailed, chapter-by-chapter inspired story based on the themes of Stoft’s work.
