Overall objective of the project: increasing the energy efficiency at the level of the centralised heating supply system in Ploiesti Municipality, by reducing the thermal energy losses resulting from the rehabilitation of the primary district heating network. The value of the result indicator at the beginning of the project is 32.36 % and at the end of the project will be 29.06 %, resulting in a percentage reduction of losses at SACET Ploiesti level of 3.3 %. Value of result indicator 2S61: Energy losses recorded on the transmission and distribution networks of the thermal agent at national level will be 0.23 %, representing the contribution of the project to the target of the overall result indicator of LIOP 2014-2020.
