Merchant Power Plant
A merchant power plant earns the majority of its revenue from wholesale market sales rather than long-term cost-of-service contracts or bundled utility rates. These plants take on energy price, capacity price, and congestion risk directly and must secure hedges or bilateral agreements to stabilize cash flows.
Merchant developers focus on regions with liquid markets, transparent nodal pricing, and robust transmission access, often pairing projects with hedges such as virtual PPAs, tolling agreements, or financial transmission rights. Financing structures rely on sophisticated risk management, collateral arrangements, and performance guarantees demanded by lenders.
Merchant exposure is increasingly relevant for hybrid plants, storage projects, and repowered assets seeking upside from price volatility. Policy changes to capacity markets, scarcity pricing, and carbon regimes directly affect merchant revenue stacks and project valuations.
Policy shifts such as carbon pricing or fuel subsidies can rapidly swing merchant economics, so sponsors maintain scenario books that stress-test cash flows under multiple policy outcomes. Merchant portfolios also monitor forward congestion indicators to adjust hedges proactively.

Why It Matters
Merchant strategies influence how investors bid in lease auctions, queue positions, and transmission rights. Tera's Asset Intelligence database lets users compare hedge structures, merchant exposure ratios, and sponsor performance so they can underwrite projects that depend on wholesale price outlooks rather than fixed offtake agreements.
