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.

Stoft demonstrates that without a properly designed spot market (specifically a Locational Marginal Pricing or LMP system), the entire market structure creates perverse incentives. He argues that "uniform pricing"—where everyone pays the same rate regardless of location—is a fantasy that ignores transmission congestion.
