WebThe average heat rates above are weighted by Net Summer Capacity. Coal Combined Cycle represents integrated gasification units. Source: U.S. Energy Information Administration, Form EIA-860, 'Annual Electric Generator Report.' WebThe repeatable determination of the turbine cycle heat rate also depends on cycle isolation. Since primary flow is measured in the feedwater line, any leakage between the flow measure-ment and the turbine stop valve must be elimi-nated or the test results adjusted accordingly. Otherwise, an erroneous measurement of heat rate will be obtained.
