Nevinnomysskaya GRES is a power plant of federal importance located in Nevinnomyssk, Stavropol krai, Northern Caucasus federal area. It is a subsidiary of Enel Russia.[1]
Construction of CHP plant as part of Nevinnomyssk Nitrogen-fertilizer plant was started in 1958, the first turbine unit was commissioned in June,1960. General designer of the plant is Rostov department of the design institute "Teploenergoprojekt".[2] The general contractor for construction is "Kavkazenergomontazh". In August 1960, Nevinnomysskaya CHP plant demerged from the plant, and in 1962 it was renamed as Nevinnomysskaya GRES. In 1970, the Unit No. 6 was put into operation, in 1972, the CCGT-170 was commissioned, it was decommissioned only in April 2015. In 1981–1997, activities to increase GRES heat capacity were carried out, in 1997–2007, GRES was technically refurbished and reconstructed.
The installed electric capacity of Nevinnomysskaya GRES[3] is 1530.2 MW. Installed heat capacity is 585 Gcal/hour. The power plant has 13 turbines and 14 boilers. Nevinnomysskaya GRES consists of CHP plant, outdoor condensing units, CCGT-170 and new CCGT-410. Process water for the power plant is supplied from Bolshoi Stavropol channel and Kuban river. The main fuel is natural gas, the reserve fuel is heavy fuel oil (mazut).
GRES is divided into Boiler and Turbine shop −1, Boiler and Turbine shop – 2 and CCGT-410.
The main equipment of Boiler and Turbine shop – 1 (CHP plant) was put into operation in 2 stages.
The main equipment of 90 bar stage (DH units No. 1 and 2) includes 4 boilers TP-15 produced by Taganrog Boiler Plant with nominal capacity 220 tons of steam per hour and 2 DH turbines PT-25-90/10 produced by JSC "Turbomotor Plant" (Yekaterinburg) with installed electric capacity of 25 MW and heat capacity of 97 Gcal/h. The main equipment of the 130 bar stage (DH units No.3, 4, 5) includes:
The main equipment of the 130 bar stage (DH units No.3, 4, 5) includes:
The main equipment of Boiler and Turbine Shop-2 is represented by 6 units (No. 6-11). Each unit consists of:
CCGT-170 includes the following principal equipment:
On 15 July 2011, a new 410 MW CCGT (CCGT-410) was started up at Nevinnomysskaya GRES. This is the first new unit that Enel has commissioned in Russia as part of an investment program aimed at increasing installed capacity, improving production and environmental parameters of the company's power plants. CCGT-410 of Nevinnomysskaya GRES is the only project of this type and scale implemented in the region. Introduction of new generating capacity allowed for a more reliable, uninterrupted power supply to the region during the XXII Winter Olympic Games and the XI Paralympic Games in Sochi.[4] The new unit features increased reliability and a high degree of automation of technological processes. The new CCGT efficiency is about 58% compared to 35 -40% of traditional Gas turbine plants.[5]
