16. Energy Efficiency and Energy SavingStudy of the technical condition of 110 kV highvoltageline showed that almost 65% of distributionlines have obvious signs of deterioration,reducing line distribution capacity to 50% orbelow.Mechanical and thermal loads experienced by distributionline wires lead to plastic deformation,thus limiting the possibility of their full load. Torestore (increase) the capacity of commissionedoverhead distribution lines, the following set ofengineering activities need to be performed:— determination of the actual technical conditionof distribution lines based on state-ofthe-artmethods using advanced tools fortechnical condition diagnosis and control;— development of activities aimed at raisingthe distribution capacity of high-voltagelines accompanied by the determination oftheir implementation priorities;— restoration of administrative documentationon high-voltage lines;— switch to distribution line load control inaccordance with the actual data concerningthermal resistance of high-voltage wiresaccompanied by integration into the systemsof process and emergency control of powersystems.The principal areas of activity performed by JSCIDGC Holding in the field of energy conservationand energy efficiency enhancement are as follows:— organization of the activities of the SDCs ofJSC IDGC Holding in the field of energy conservationand energy efficiency enhancement;— improvement of the regulatory framework;— creation and improvement of conditions fordeveloping and implementing innovativetechnologies in the distribution grid sector;— ensuring the implementation of the Programof the Enhancement of Energy Conservationand Energy Efficiency of the SDCs of JSC IDGCHolding.157
