- Projects are aimed at replacing two turbines, increasing their capacity to 120 MW each from 100 MW, and refurbishing the boiler at Sredneuralskaya GRES as well as replacing the boiler at Nevinnomysskaya GRES
- Commissioning of modernised units is scheduled in 2025
Moscow, September 21th, 2020 – Enel Russia was awarded equipment modernisation projects at Sredneuralskaya GRES and Nevinnomysskaya GRES in the second round of the equipment modernisation tender launched by the System Operator.
“The equipment modernisation project is key to our assets, whose operation will be enhanced through state of the art solutions. This approach is in line with the renewed commitment by Enel Russia to a more sustainable generation mix, to be achieved by further improving our conventional generation assets alongside our more recent investments in renewables.”
The projects were selected on the basis of the minimum levelised cost of energy (LCOE) applied by the tender participants. In line with the tender results, generating companies committed to deliver capacity for a 16-year period, and to use equipment compliant with local sourcing requirements in their modernisation projects.
The first modernisation project at Sredneuralskaya GRES envisages the replacement of the 100 MW turbine № 7 with a new 120 MW turbine. The load factor for the generating equipment presented in the project is more than 0.8. Commissioning of the modernised unit is scheduled for the first quarter of 2025.
The approved capex of the project amounts to 9254.9 roubles per kW.
The second modernisation project at Sredneuralskaya GRES envisages the replacement of the 100 MW turbine № 6 with a new 120 MW turbine and the refurbishment of boiler № 9, which has a 480 t/h capacity and powers turbine № 6. The load factor for the generating equipment presented in the project is more than 0.9. Commissioning of the modernised equipment is scheduled for the fourth quarter of 2025.
The approved capex of the project amounts to 11661.7 roubles per kW.
The modernisation project for Nevinnomysskaya GRES involves the replacement of boiler № 4, which has a 480 t/h capacity and powers 80 MW turbine № 3. The load factor for the generating equipment presented in the project is more than 0.7. Commissioning of the modernised unit is scheduled for the first quarter of 2025.
The approved capex of the project amounts to 17790.4 roubles per kW.
In June 2019, another modernisation project for Nevinnomysskaya GRES was selected by the Government Commission in the first round of the equipment modernisation tender for 2022-2024. The project includes the refurbishment of the 480 t/h boiler № 5, which powers 50 MW turbine № 4. The load factor for the generating equipment presented in the project is more than 0.9. Commissioning of the modernised unit is scheduled for the first quarter of 2022.
Sredneuralskaya GRES, with 1,578.5 MW of power capacity, including the 419 MW CCGT unit introduced in 2011, and 1,327 Gcal/h of thermal capacity, is one of the largest heat suppliers in the Sverdlovsk power system, covering about 30% of heat and hot water consumed by Yekaterinburg and approximately 100% of the needs of the nearby towns such as Verkhnyaya Pyshma and Sredneuralsk. The power output share of Sredneuralskaya GRES in the power system of Sverdlovsk region is about 10%.
Nevinnomysskaya GRES, with 1,530.2 MW of power capacity, including the 410 MW CCGT unit introduced in 2011, and 585 gcal/h of thermal capacity, is one of the largest power plants in the South of Russia. The plant, which consists of 12 turbines and 14 boilers, meets the power needs of North Caucasus and supplies energy to the businesses and the citizens of Nevinnomyssk city in the Stavropol Region.
 The levelised cost of electricity represents the average estimated cost of production of a unit of electricity which includes the cost of construction and operation of generating equipment throughout the entire life cycle
