⚡ '''Power purchase agreement (PPA)''' is a long-term contract between an electricity generator and a buyer — often a utility, corporate off-taker, or government entity — that establishes the terms for the sale of power, typically from a renewable energy project such as a wind farm or solar installation. Within the insurance industry, PPAs are significant both as insurable contracts underlying large [[Definition:Energy insurance | energy]] and [[Definition:Infrastructure insurance | infrastructure]] risk portfolios, and as instruments whose financial performance depends on conditions that insurers and [[Definition:Reinsurance | reinsurers]] are increasingly asked to guarantee or de-risk. The growth of renewable energy globally has made PPAs a central feature of the risk landscape for [[Definition:Specialty insurance | specialty]] and [[Definition:Commercial insurance | commercial]] insurers that serve the energy sector.

🔧 A PPA typically spans fifteen to twenty-five years and fixes or indexes the price at which the generator sells electricity, creating a predictable revenue stream that enables [[Definition:Project finance | project financing]]. From an insurance standpoint, multiple coverage layers wrap around PPA-backed projects. [[Definition:Property insurance | Property]] and [[Definition:Business interruption insurance | business interruption]] policies protect the physical assets and revenue streams; [[Definition:Construction insurance | construction all-risk]] and [[Definition:Delay in start-up insurance (DSU) | delay in start-up]] coverage applies during the build phase; and [[Definition:Liability insurance | liability]] policies address third-party exposures. More recently, [[Definition:Parametric insurance | parametric]] and [[Definition:Weather risk transfer | weather risk transfer]] products have emerged to cover the volumetric risk inherent in renewable generation — the possibility that wind speeds or solar irradiance fall below expected levels, reducing the energy available for delivery under the PPA. Insurers and [[Definition:Managing general agent (MGA) | MGAs]] specializing in renewable energy have developed bespoke products that sit at the intersection of traditional insurance and financial hedging to address this gap.

📊 As the global energy transition accelerates, the insurance industry's ability to underwrite PPA-related risks shapes the pace at which renewable projects can secure financing and reach commercial operation. Lenders and investors in markets from the United States and Europe to Southeast Asia and Latin America routinely require comprehensive [[Definition:Insurance program | insurance programs]] as a condition of funding, making insurers and [[Definition:Insurance broker | brokers]] integral participants in the project finance ecosystem. The emergence of revenue-guarantee and generation-shortfall products represents a notable expansion of the industry's risk appetite, blurring the traditional boundary between [[Definition:Indemnity | indemnity]]-based insurance and financial [[Definition:Guarantee | guarantee]]. For insurers, PPA portfolios offer long-duration premium streams but demand sophisticated modeling of [[Definition:Climate risk | climate risk]], technology degradation, and counterparty creditworthiness over contract horizons that stretch well beyond typical policy periods.
