Enel Russia : three projects selected in second round of equipment modernisation programme tender

The projects were selected on the basis of the minimum levelised cost of energy[1] (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.

Sredneuralskaya GRES

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.

Nevinnomysskaya GRES

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.
