Karaganda Energocenter LLP

karaganda energocenterKaraganda CHPP-1 and CHPP-3 generated over 4.429 billion kWh of electric power and 3.3 million Gcal of heat in 2021. There has been an increase in the production of electric power over the past 10 years, due to the large-scale projects implemented for CHPP-3 extension, where a new turbine unit and a unit, including a new boiler unit and a turbine, were assembled in the period from 2012 to 2016. By new equipment, Karaganda CHPP-3 has reached an electric capacity of 670 MW, a heat capacity of 1432 Gcal/h Gcal, and became the largest CHPP in Kazakhstan supplied.

The generated electrical power and heat have been almost completely supplied to the consumers. In 2021, own-need power consumption was reduced by the plants and fuel oil savings occurred compared to 2020 and 2012. These indicators are associated with the annual implementation of planned overhauls and maintenance of equipment and measures aimed at further high-quality power supply and power efficiency improvement.

In preparation for the 2021-2022 heating season, 16 boilers and 10 turbines were repaired. The boiler equipment underwent overhauls of 3 boilers and maintenance of 13 boiler units. Overhauls of 3 turbines and maintenance of 7 turbine units were carried out on turbine equipment. A large amount of work was done with auxiliary equipment and ash disposal area. Special attention was paid to solving issues of heat supply quality. The heating equipment was prepared: cleaning, flushing and necessary repair and preparation work were carried out on water heaters and peak boilers. A complete replacement of insulation has been made on the supply pipeline located on the territory of the CHPP-3. All these measures will increase the temperature at the output to the heating system.

Ust-Kamenogorsk CHP LLP

uktetsUst-Kamenogorsk CHP LLP (UK CHP LLP) is a combined heat and power plant located in the east of the Republic of Kazakhstan, in the city of Ust-Kamenogorsk. It is the largest CHP plant in the region.

The production of heat and electricity, which is the main activity of the Facility, is carried out in a combined way. To this date, 9 boiler units and 8 turbine units have been installed at the station. The thermal power generated by the station covers more than 80% of the load of the housing and utilities sector of the city. Provides thermal power to the largest industrial facilities in the region, such as Kazzinc LLP and UMP JSC.

One of the major investment projects in 2013-2016 was the construction of a turbine unit No. 12. The investment volume for the installation of a new turbine amounted to 11 billion 484 million tenge.

The project for the construction and commissioning of a new turbine unit No. 12 had produced the following goals:
• meeting the increased needs of consumers in the supply of electrical energy;
• provision of production electric power with efficient modern technological equipment;
•  additional generation of electricity according to the heating cycle;
• increasing the efficiency of the plant by using excess high-pressure steam through a steam turbine, as well as using steam resulting from extraction for process steam supply and city heating (cogeneration), instead of steam reduction in reduction-cooling units (RCU). The new 120 MW turbine generates about 800 million kWh per year.

The implementation of the project has significantly increased the efficiency and reliability of the plant. The new turbine unit has an air-cooling generator instead of hydrogen-air, which has improved fire safety. The operator can control the turbine unit using modern automatic systems; to prevent the development of an emergency situation, a modern microprocessor protection system and a vibration monitoring system for the turbine unit were installed.

In recent years, the Facility has significantly increased the expenses on the investment activities. Since 2017, UK CHP LLP has carried out a number of activities for the reconstruction and modernization of equipment, expansion of energy capacities, in order to obtain positive results, the main of which are as follows:

1. Electricity generation increased by 416.7 million kWh (23.8%), electricity supply increased by 360.8 million kWh (24.6%). Increased average annual electric power by 47.6 MW (by 23.8%);
2. Share of own electricity consumption decreased from 15.54% to 14.98% (as a percentage);
3. Reduced fuel oil consumption by 510 tonnes (33.3%);
4. Power factor increased by 12.8%. Heat efficiency coefficient increased by 1.8%;
5. Specific reference fuel consumption for power supply decreased by 3.4 kgce/Gcal (or 1.9%);
6.  Average annual steam load on boiler units was increased from 1074 to 1252 t/h (by 178 t/h or 16.6%).
