Ekibastuz CHP successfully powered through the 2024–2025 autumn-winter season, delivering reliable equipment performance and uninterrupted heat supply to customers.
Pre-season upgrades and repairs slashed fuel consumption significantly: mazut (heavy fuel oil) usage dropped 3.5 times, from 3,284 tons to 949 tons. This reduction reflects stable operation of core equipment and a boost in the plant’s overall efficiency. 

In June 2024, Ekibastuz CHP was placed under the trust management of  Samruk-Energy JSC Its subsidiary, Energy Solutions Center LLP swiftly executed extensive repairs and prepped the plant for winter.
The work included major and routine maintenance on ten boiler units, one turbine unit, auxiliary systems, and plant-wide infrastructure. Repairs were also completed on the ash dump dam, buildings, and structures, alongside the construction of a clarified water pipeline within the plant’s premises. 

These efforts, part of the 2024–2025 heating season preparations, reduced core equipment wear by 3.7%, from 51.8% to 48.1%, and cut technological disruptions by 90%, from 191 to 18. Notably, no disruptions during the autumn-winter period impacted heat supply reliability. 

With the heating season concluded, Ekibastuz CHP is gearing up for the next autumn-winter period. Ongoing repairs are in full swing, with plans for 11 maintenance projects, including major overhauls of six more boiler units and chimney No. 3. 

On April 26, a citywide cleanup event was held in Astana as part of the environmental initiative "Taza Kazakhstan".

Samruk-Energy JSC employees participated in the event and helped with landscaping at the intersection of S. Nurmagambetov street and R. Kosharbayev avenue.

Sustainable development and environmental responsibility are among the top priorities of Samruk-Energy JSC.

The first quarter of 2025 marked a true breakthrough. Thanks to the effective collaboration between Bogatyr Komir LLP and NC Kazakhstan Temir Zholy JSC, a record 3.9 million tonnes of coal were shipped to consumers in February.

Every day, solid fuel was dispatched via 33 train routes — reliably, precisely, and without a single disruption. This achievement was made possible through the strong coordination and dedication of both the mining and railway teams.

To mark the occasion, Vadim Kopylov, Director of the Integrated Planning Department at NC KTZh JSC, sent a letter of appreciation to Bogatyr Komir.

"We appreciate Bogatyr Komi LLP’s proactive efforts to enhance loading operations and make efficient use of station infrastructure. These initiatives have played a key role in ensuring the consistent dispatch of block trains, achieving strong production results, and improving railcar turnaround times" - the letter stated.

Samruk-Energy JSC continues to improve the social and workplace conditions of production staff across its subsidiaries. As part of a broader social program launched during the Year of skilled professions, Almaty Power Plants (APP) has introduced, for the first time, a project to provide free hot meals to employees working in production workshops.

At the A. Zhakutov CHP-2 plant alone, over 900 employees now benefit from high-quality, well-balanced meals every day. To accommodate 24/7 operations, the cafeteria remains open around the clock. The menu is carefully planned, dietary standards are strictly followed, and most importantly—an environment of respect and care has been fostered. Professional chefs prepare meals with dedication, food technologists monitor quality, and the initial response from staff has been overwhelmingly positive.

“We truly appreciate the management’s focus on our well-being. This is a meaningful investment in our health and daily comfort. The food is great, the portions are generous, and everyone feels satisfied. It positively impacts our performance”- said Mukhamedzhan Oralbekov, production foreman at PRE EnergoRemont.

The initiative will soon expand to other facilities, including the B. Orazbayev CHP-1, CHP-3, Sh. Chokin Kapshagay HPP, the HPP Cascade, WHC, and others. In total, nearly 3,000 employees will be covered by the free meal program.

To strengthen preventive measures for reducing workplace injuries and ensuring safe working conditions, all enterprises within Samruk-Energy JSC Group are conducting a Safety and Occupational Health month-long campaign, timed to coincide with World Day for Safety and Health at Work. 

Throughout the month-long campaign, all production departments conduct scheduled workplace audits to further enhance occupational safety. 

As part of the Year of Safety and Occupational Health within Samruk-Energy JSC Group, new tools for ensuring workplace safety are being introduced. For instance, Almaty Power Plants has established a Centralized Safety Compliance Monitoring Center. This system enables real-time monitoring of adherence to safety standards, including the use of personal protective equipment, identification of potentially hazardous areas, and oversight of workers’ conditions. 

During the month-long campaign, employees in the production departments of subsidiary enterprises participate in training on emergency response procedures and workshops on first aid. Elevating the culture of safety in the workplace is an integral part of the strategy to achieve zero injuries. 

The Ombudsmen Council of Samruk-Kazyna JSC’s portfolio companies held an off-site meeting in Almaty region, attended by Nariman Akylov, Ombudsman of Samruk-Energy JSC. 

Council members visited Samruk-Energy JSC subsidiaries—Moynak HPP and AZhC, as as well as KEGOC JSC’s Almaty MPTL. They learned about electricity generation and transmission processes and met with company employees. 

Additionally, the ombudsmen attended a Forum on internal communications and procurement activities of  Samruk-Kazyna JSC group of companies. The forum discussed principles of professional workplace conduct, with a dedicated session on procurement processes and support for domestic producers. 

Access to clean water is a key part of ensuring every employee’s well-being. Modern drinking fountains have now been installed across all of the company’s production facilities. Each unit is equipped with filters capable of purifying up to 5,000 tons of water. A new water supply system has also been implemented to provide workers with clean, safe drinking water.

"Before, getting drinking water meant a long walk. Now the fountains are just steps away. I drink around five liters a day—it's physical work, and staying hydrated is essential"- said Nurlan Suleiman, a mechanical fitter at the A. Zhakutov CHP-2 turbine shop.

This project is a strong example of how practical technical solutions can directly enhance the comfort and health of employees. For those working in the shops, these new drinking fountains have become a real lifeline during hot days and demanding shifts.

Samruk-Energy remains committed to improving the workplace and everyday conditions for its industrial workforce.

"Samruk-Energy" JSC ensured uninterrupted electricity and heat supply throughout the 2024–2025 autumn-winter period and has successfully concluded the heating season. During this period, the company’s thermal power plants (TPPs) generated 18.6 billion kWh of electricity, while the amount of heat energy supplied reached 4.4 million Gcal. Throughout the entire heating season, the power stations operated in normal mode, adhering strictly to the temperature schedules for heat delivery.

A total of 114 repairs on 105 units of main equipment are scheduled for this year. The repair campaign will be conducted in accordance with the approved schedule, ensuring that all Samruk-Energy stations are fully prepared for the upcoming heating season.

"Bogatyr Komir" LLP continues its drive to modernize operations. The company’s technical fleet has grown with the addition of five new dump trucks, each with a payload capacity of 180 tons.

“The introduction of this advanced equipment, launched during the Year of Skilled Trades, will improve working conditions for our employees and increase the efficiency of our production processes. This is a significant contribution not only to our company but also to Kazakhstan’s coal industry as a whole”,-  said General Director Kairat Rgaiybek.

The new trucks will be operated by 20 experienced and highly skilled drivers from the Technological Transport Department. Among them is crew foreman Nurgali Shaizadinov, who expressed gratitude for the trust placed in him and his team’s readiness to achieve outstanding results. The dump trucks will be deployed for overburden removal operations.
