Gencos up output following accident at Sayano-Shushenskaya HPP

MOSCOW. Aug 17 (Interfax) - The OGK-6 generating company's Krasnoyarsk GRES-2 state district power plant is being brought to maximum capacity following the accident at the Sayano-Shushenskaya Hydroelectric Power Plant (HPP), OGK-6 said.

The genco said that it had been instructed by the Krasnoyarsk regional dispatch division to bring GRES-2 to maximum capacity as soon as possible.

At present, Krasnoyarsk GRES-2 is operating at a capacity of 210 megawatts. After the initiation of reserve machinery, the capacity will come to over 1,000 megawatts. The term for maximum capacity operation will be set after a full assessment of the situation at the Sayano-Shushenskaya HPP.

At OGK-6, an operational team has been formed to coordinate the increase in Krasnoyarsk GRES-2's capacity, which will also oversee the provision of fuel for power production.

The accident at Sayano-Shushenskaya HPP took place on Monday morning, when part of the dam imploded, which resulted in the destruction of two sluices and three hydraulic units, as well as the collapse of a turbine room roof. Operations at Sayano-Shushenskaya HPP, which has generating capacity of 6.72 gigawatts, have been suspended.

OGK-6 includes the Kirishi State District Power Plant (GRES), Novocherkassk GRES, Ryazan GRES, Cherepovets GRES, and the Krasnoyarsk-2 and Krasnoyarsk-24 GRES, with installed capacity of 9,000 megawatts.

The OGK-3 genco also said it was ramping up output at its Kharanorsky and Gusinoozersrky plants. Kharanorsky, in the Chita region, is bringing one of its turbines up to its maximum of 215 megawatts from 160 megawatts. Its other turbine has been stopped for maintenance.

The Gusinoozersky plant in Buryatia with three turbines is running at its full capacity of 570 megawatts, compared with 425 megawatts prior to the Sayano-Shushenskaya accident.

OGK-3 includes the Kostroma, Pechora, Cherepetsky, Kharanorsk, Gusinoozersky, and Yuzhnouralsky power plants with capacity of 8,500 megawatts. MMC Norilsk Nickel owns the genco.

The Kemerovo-based Kuzbassenergo or TGK-12 generating company said it had increased overall capacity 225 megawatts so far to 2,066 megawatts at all power plants, including 1,876 megawatts in the region itself, by drawing on back-up capacity. It said another 900 megawatts of capacity could be deployed in the next few hours.
