Investments
One of the most significant developments on the Russian energy market in 2018 was approval of the electric power industry modernization program (DPM-2). In 2019, three gas-fired generating units of Surgutskaya GRES-2 were selected to take part in the modernization program, Unipro will accomplish these works untill the end of 2025. The planned investments will total to about RUB 10 bn. These investments will secure Unipro PJSC attractive capacity payments over a period of 16 years. The company is also considering its participation in further auctions including deep modernization projects.
Unipro PJSC investment program within the Capacity Supply Agreement (DPM) was referred to a construction of combined cycle facilities at Surgutskaya GRES-2, Shaturskaya GRES and Yaivinskaya GRES as well as construction of the third power unit at Berezovskaya GRES. Another project under the investment program was modernization of two existing power units at Berezovskaya GRES with their capacity increase by 100 MW. A total capacity commissioned is about 2 500 MW, total construction investments – around RUB 110 bn.
Standard single-shaft condensation power units with the use of CCGT technology (CCGT-400 units) were constructed at Shaturskaya GRES, Yaivinskaya GRES and Surgutskaya GRES-2.
As of today, CCGT technology is the most efficient method of thermal generation. CCGT efficiency level is about 56% (versus 40% efficiency of traditional steam power units), and specific reference fuel consumption per 1 kW/h makes about 220 grams. High performance indicators inherent to CCGTs considerably reduce a prime cost of energy output and reduce emission of harmful substances into the atmosphere.
A 800 MW lignite-fired unit at Berezovskaya GRES was commissioned in 2015. The power plant is located in the area of Kansko-Achinsky coal pit which is rich by its lignite reserves, this power plant is one of the most efficient coal-fired power stations in Russia.
The company fulfilled all obligations towards the Government of the Russian Federation in 2015.
