This is not merely a summary; it is an examination of the paradigm shift Stoft introduced to the field—moving the conversation from "how to deregulate" to "how to design a functional market."

Perhaps the deepest tension Stoft explores is between reliability as an engineering necessity and reliability as an economic good. Traditionally, utilities built reserve margins based on deterministic criteria (e.g., loss-of-load-expectation < 1 day in 10 years). Competitive markets, however, rely on price spikes during scarcity events to incentivize capacity investment. This leads to the “missing money” problem: if price caps prevent scarcity prices from rising to the value of lost load (VOLL), then investors will under-build capacity. Stoft’s solution involves either a pure energy-only market with very high price caps (politically difficult) or a capacity market that administratively determines the required reserve margin. He rigorously compares these approaches, demonstrating that while capacity markets can fix underinvestment, they introduce their own distortions, such as over-procurement and regulatory gaming. power system economics steven stoft pdf
