  "term": "Repowering",
  "field": "Energy",
  "definition": "For power plants that use combustible fuel, repowering refers to refurbishing a plant by replacing the power-generating technology with a new prime mover and energy source (for example, switching from coal to natural gas). As a result of this replacement, the plant’s efficiency usually improves, its emissions decline, or its generation capacity increases. The repowering process usually uses existing facility infrastructure (for example, roads, buildings, interconnection equipment, and fuel and ash storage and handling).\n\nFor wind farms, repowering refers to replacing existing wind turbines with new, generally larger and higher capacity turbines or with more efficient components. These replacements result in increased nameplate capacity or convert kinetic wind energy into electricity more efficiently. When a wind farm undergoes a full repowering, the existing turbines are replaced with newer turbines and new towers and foundations are often installed. When a wind farm undergoes a partial repowering, the existing towers and foundations are usually retained, while the turbines and other components are replaced.",
