The end of the world will no longer be
Power engineers explain that the instability of the power system is due to three factors: isolation, equipment wear and lack of the necessary reserve. Professionals also have something to blame - how the system entered the 1990-ies, so down to the "tenth", no serious investments were made here.
They did not invest either, because the island's energy sector left very few industrial consumers. The lion's share of the load is the population and household consumption. In market conditions, the population is not able to pay for such infrastructure on their own, without the help of large industry.
The island’s power supply is provided by two enterprises - operated by RAO ES of the East of Sakhalin TPP (1965 of the year of construction) and Yuzhno-Sakhalinskaya CHPP-1 (of 1976 of the year of construction). The main problem today is the power plant. “GRES is a steam coal power station designed to operate in the base mode. However, for a long time it was used to cover peak loads. Twice a day, the equipment started or stopped. As a result, there is a high degree of equipment wear, ”comments Sergey Tikhomirov, Technical Director of RAO Energy Systems of the East Holding.
The power plant is located right on the shore of the Terpeniya Bay, north of Yuzhno-Sakhalinsk. The proximity of the sea - and dignity and disadvantage. During the operation, there were also anomalous colds, when the whole bay was ice-bound and, in order to ensure the water intake, tanks would direct fire on the ice shell; there were warm years when the water warmed to such an extent that mollusks began to multiply in the water intake system, forcing it to substantially limit production.
Each such restriction until recently led to fan outages. The reason is the lack of reserve. The reserve, which allowed at least a little to weaken this "stranglehold," appeared only last year, when the 1 power unit was commissioned at the Yuzhno-Sakhalinskaya CHPP-5. The launch of equipment, by the way, became the first major realized investment project in the Far Eastern energy sector for the last 30 years.
