Energy Complex of Sakhalin region

The Sakhalin region energy sector is characterized by low reliability and long and frequent interruptions in power supply to consumers. In 2015, by order of the Russian Presidential Envoy to the Far East, the development of the Program for Improving the Reliability of the Regional Energy Sector began. TEK Mosenergo launched the development of the program on its own initiative, hiring EF-TEK as an executor.

EF-TEK's scope of services included:

• analysis of the region's 0.4-220 kV power system - balances, characteristic modes, age structure, availability of transportation infrastructure and climatic conditions (including visits to 30 power facilities in 14 of the region's 17 districts)
• Analysis of failure statistics, analysis of circuit and mode limitations (based on the calculation model of 35 kV and above), identification of "bottlenecks";
• development of priority measures to improve the reliability of existing consumers. Estimation of the scope and cost of measures;
• Analysis of forecast balances of electric power and capacity, development of measures to improve system reliability taking into account prospective consumers (including on the basis of small distributed generation);
• development of a tariff-balance model for the power nodes on Sakhalin Island (including the development of a tariff-balance model for the power nodes of Sakhalin Island. Sakhalin Island (including isolated areas), selection of a reliability improvement option with minimal tariff consequences.

The work was suspended in May 2016 due to RusHydro's decision.
