What is the operating life of a CHP unit?
CHP units are usually run until the cost of operating them exceeds any savings they make, or their reliability falls below the operator’s requirements. Typically we would expect a packaged CHP to last 15 years. A large CHP plant may have an operating life of 25 years or more. Analysis of the return on investment will show when a specific scheme will have recovered the cost of installing the scheme, this period is typically shorter than the plant operating life.
