Saving Potentials in SMEs
The saving potentials of SME facilities is shown on the basis of a classification into three groups of facilities of overall energy use (heating, fuel and electricity). The industrial energy audits or energy analysis projects started between 2004-2009 are shown in the tables as facilities whose overall energy use is under 10 GWh/a (103 facilities), whose overall energy use is 10-70 GWh/a (63 facilities) and whose overall energy use is 70-500 GWh/a (9 facilities).In terms of the overall energy use of industries, the largest (>500 GWh/a) facilities are mainly process industry enterprises with energy savings agreements, where the auditing model is usually the two-stage process industry model. The results of these analyses are not dealt with more specifically in this respect.
SME energy use below 10 GWh/a
Between 1992-2009 altogether 539 facilities in the SME sector were audited, whose joint annual overall energy use is over 1,770 GWh. The saving potentials of heating energy and fuel in these facilities has on average been 24% (c 226 GWh/a), the saving potentials of electrical energy about 8% (c 65 GWh/a) and the saving potentials of water about 12% (c 0.6 million m3).SME energy use between 10-70 GWh/a
Between 1992-2009 altogether 201 facilities in the SME sector were audited, whose joint annual overall energy use is over 5,000 GWh. The saving potentials of heating energy and fuel in these facilities has on average been 21% (c 586 GWh/a), the saving potentials of electricity about 6% (c 135 GWh/a) and the saving potentials of water about 7% (c 2,3 million m3).SME energy use between 70-500 GWh/a
Between 1992-2009 only 33 of these facilities in the SME sector were audited. The emphasis of the energy audits in this category of the SME sector is for the most part clearly under 70 GWh a year concerning the facilities’ energy consumption. The saving potentials of heating energy and fuel in these facilities has on average been 12% (c 450 GWh/a), the saving potentials of electrical energy about 4% (c 51 GWh/a) and the saving potentials of water about 10% (c 1.5 million m3).Because the target group of facilities is small in number, it is apparent that the results for individual facilities significantly affect the mean figures. In comparing the saving potentials of heating in other groups, where energy use is under 70 GWh, the saving potentials observed in these facilities whose overall energy use is 70-500 GWh/a is clearly lower. There may be large annual variations in this group because of the great emphasis on individual facilities.
