The paper presents what was done at the Heating Plant EKOTERM at Żywiec (Poland) for energy efficient use of electricity. In 1986 a new boiler house "Pod Grapą" started running. The project of the plant and following the equipment were to large for that time and for future heat demands. A number of actions were done to decrease the electricity usage per one unit (GJ) of produced and delivered heat. The reduction of the network pressure by the way of replacing of exploited electric motors (into motors of lower rotation speed) and than by an exchange of pumps and using frequency converters for all main drives (pumps, fans) caused large electricity savings. At the beginning of exploitation of the Heating Plant the heat production required 17 kWh/GJ, while after the modernisation only 4.5 kWh/GJ are necessary. The payback of the modernisation is estimated as 1.3 year.
