  "text": "The operator determines amounts of net measurable heat based on the fuel input and the measured efficiency related to the heat production:\nQ = ηH · EIN\n(Equation 5)\nEIN = Σ ADi · NCVi\n(Equation 6)\nWhere Q is the amount of heat expressed in TJ, ηH is the measured efficiency of heat production, EIN is the energy input from fuels, ADi are the annual activity data (i.e. quantities consumed) of fuels i, and NCVi the net calorific values of fuels i.\nThe value of ηH is either measured by the operator over a reasonably long period, which sufficiently takes into account different load states of the installation or taken from the manufacturer's documentation. In that regard the specific part load curve is to be taken into account by using an annual load factor:\nLF = EIN /EMax\n(Equation 7)\nWhere LF is the load factor, EIN the energy input as determined using Equation 6 over the calendar year, and EMax the maximum fuel input if the heat producing unit had been running at 100 % nominal load for the full calendar year.\nThe efficiency should be based on a situation in which all condensate is returned. A temperature of 90 °C should be assumed for the returned condensate.",
