E.ON Russia’s (starting from June 2016 – Unipro PJSC) Investment program includes construction of combined cycle facilities at Surgutskaya GRES-2, Shaturskaya and Yaivinskaya GRES as well as construction of the third power unit at Berezovskaya GRES. Another project under the investment program is modernization of the two existing power units at Berezovskaya GRES with their capacity increase by 100 MW. The aggregate capacity to be commissioned is about 2 500 MW. The value of investment program is around 110 billion rubles.
Investment projects implemented by E.ON Russia (starting from June 2016 – Unipro PJSC) stipulate for the production facilities upgrades to satisfy the growing electricity demand in the area of the Company activities.
At three power stations – Shaturskaya, Yaivinskaya GRES and Surgutskaya GRES-2- standard single-shaft condensation power units were constructed with the use of CCGT technology (CCGT-400units).
As of today, CCGT technology is the most efficient method of thermal generation. CCGT performance factor is about 56% (versus 40% performance of traditional steam power units), and specific reference fuel consumption per 1 kW/h makes about 220 gram. The high performance indicators inherent to CCGts considerably reduce the prime cost of energy output and reduce emission of harmful substances into the atmosphere.
2015 saw the commissioning of an 800 MW lignite-fired unit at Berezovskaya GRES. The power plant is located in the area which is rich in lignite, with its Kansko-Achinsky coal pit; this power plant is one of the most efficient coal-fired power stations in Russia.
