Investors should still evaluate its revenue model, industry-specific KPIs, valuation framework and the risks that can change the group's economics. ## Industry Overview Wind power producers own and operate onshore and offshore wind farms that sell electricity under long-term agreements. Output follows wind resource, and returns depend on tax credits, equipment cost, interest rates and grid access. The first numbers to compare across companies here are operating capacity, capacity factor and contracted share and price. ## Key Industry Metrics - **Operating capacity**: The wind capacity in service. It sets the base for generation and revenue, and growth depends on projects reaching operation. - **Capacity factor**: Actual output divided by what turbines could produce at full power. It depends on wind resource and turbine quality, and offshore sites usually achieve higher figures than onshore. - **Contracted share and price**: The portion of output under long-term agreements and the price paid. A high share at a fixed price gives stable income but limits upside. - **Development pipeline**: Projects planned or under construction. It shows growth potential, though permits, equipment and grid access can delay completion. - **Operating cost per megawatt-hour**: Maintenance and operating cost per unit produced. It has no fuel cost, so it reflects turbine reliability and repair expense. ## Primary Macro Drivers - **Tax credits and renewable mandates**: Credits and mandates support project returns and buyer demand, so policy shows in the development pipeline and new capacity. - **Turbine cost and supply chain**: Turbine prices and supply chains set the capital cost of each project, shown in operating cost and returns. - **Interest rates**: Projects are financed with debt, so borrowing costs affect returns and the pace of new builds. - **Transmission access**: Lines to carry power from windy areas are needed to sell output, so access shows in curtailment and capacity factor. ## Major Risks - **Policy changes**: Changes to credits or mandates can alter the value of projects not yet built; watch pipeline conversion and policy disclosures. - **Wind resource variability**: Wind varies by season and year, so output can fall short of plan; watch capacity factor against expectations and revenue. - **Offshore project cost overruns**: Offshore projects face higher costs and delays, and contracts may not adjust; watch cost updates, delays and impairments. - **Curtailment**: Output may be cut when the grid is congested; watch curtailment, capacity factor and the contracted share and price. ## Industry Characteristics | Characteristic | Profile | | --- | --- | | Cyclicality | Defensive | | Capital Intensity | High | | Regulatory Intensity | Medium | | Industry Maturity | Growth | | Geographic Importance | U.S. | ## Wind Power Producers Filers in the SEC Record 28 companies with annual reports in the dataset are classified by the SEC in the Standard Industrial Classification codes 4911, 4991.

A company's SIC code reflects its main business as the SEC records it, so it can differ from how an index provider or analyst classifies the company, and a diversified group appears under only one code. ## Where to Go Next The Wind Power Producers guide describes how the industry earns money, what to measure and what can go wrong.
