Sakhalinskaya GRES-2

The end of the world will no longer be

Sakhalinskaya GRES-2

The people on Sakhalin are accustomed to a lot, this is evidenced by the patience with which they endure on the island, for example, the regular "outage" of electricity. The practice of rolling blackouts has existed here until recently - every family has NZ made of flashlights, kerosene lamps and candles.

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.

There is certainly an industrial consumer on the island. The most significant is the system of Sakhalin oil and gas enterprises led by the “pearl” - a plant for liquefying natural gas. However, the plant, which consumes almost 20% of the power of the power system, has nothing to do with the system itself: the gas workers are sitting on their own generation.

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.

Experts give the current Sakhalin TPP a maximum of three to four years of life. She will be replaced by a new station, designed for all conditions. The site for construction was not chosen randomly. This is the edge of the coast of the Tatar Strait. According to the designers, building from the "inner" side of the island means providing natural protection against the tsunami. It will be a large coal enterprise, and coal power plants "in the open field" in the country have not built the last 20 years. Paving coal generation is incomparably expensive to gas stations, but there are obvious advantages - fuel diversification (Yuzhno-Sakhalinsk CHP-1 will be completely gasified by the end of this year) and support for the Sakhalin coal industry, which is a question for four thousand people.
