At the government session chaired by Prime Minister Askar Mamin, Minister of Energy Nurlan Nogayev reported on the results of the heating season and preparations for the upcoming autumn-winter period.
In general, according to the head of the Ministry of Energy, the heating season in Kazakhstan was stable.
"The winter maximum load was noted on Dec. 28, 2020, and amounted to 15,822 MW, which is 4% more than last year," Nogayev said.
Over the past heating season, 36 power plant shutdowns were allowed with a decrease in electricity generation to zero MW, which is 14% less than in the previous heating season.
The Minister of Energy noted that in recent years, cases of damage to reinforced concrete supports of power transmission lines of the Unified Electric Power System of Kazakhstan due to adverse natural phenomena (hurricane wind, ice formation and heavy precipitation) have become more frequent.
In this regard, in order to increase the reliability and stability of electrical networks to unfavorable natural and climatic influences, Nogayev turned to colleagues from the Ministries of Industry and Infrastructure Development, Trade and Integration with a proposal to revise the requirements of standards and other norms for the quality of supports used in electrical networks and their structural elements.
During the current heating season, there were 44 cases of non-compliance by heat supply enterprises with temperature schedules of heating networks approved by local executive bodies, which is 8% less than last year.
The main reason for non-compliance with the schedules is deficiencies in equipment operation.
A problematic issue during the heating season is the significant volume of accounts payable for fuel.
Today, the debt of energy producing organizations to KazTransGas-Aimak JSC is 667 million tenge (last year, the debt was 7 billion 481 million tenge).
There is also a debt of energy producing organizations to Bogatyr-Komir LLP in the amount of 1 billion tenge.
Utilities, wholesale consumers, energy supplying and energy transmission organizations have debts to energy producing and energy transmission organizations in Mangystau, West Kazakhstan, Aktobe, Almaty, East Kazakhstan, Zhambyl, Karaganda, Kostanay, Akmola, Kyzylorda, Pavlodar regions and in the cities of Nur-Sultan, Almaty and Shymkent.
'These debts to suppliers of services for the production and transmission of electrical energy negatively affect the timely implementation of repair work of energy producing and transmission organizations.
“In this regard, local executive bodies need to strengthen and intensify work on repayment of debt for communal services,” Nogayev said.
Monitoring of the heating season has identified a number of regions that require special attention in preparation for the next heating season.
West Kazakhstan region
There are questions about non-payment and accumulation of debts between market entities, which affects payments for consumed gas from energy producing organizations.
Due to the differentiation of tariffs for electric energy by groups of consumers, energy supplying organizations acting as guaranteeing suppliers face a number of problems in the process of carrying out their activities. One of these issues is the outflow of consumers — legal entities to small energy supplying organizations due to the difference in tariffs between guaranteeing suppliers and unregulated energy supplying organizations.
According to the results of the outflow of legal entities from BatysEnergoResursy LLP to other ESOs, the Batysenergoresursy LLP debt to energy producing and transmission organizations as of May 1, 2021 is 2 billion 62 million tenge.
Over the past years, due to the unsatisfactory technical condition, frequent emergency shutdowns of boilers at CHPP-2 of ArcelorMittal Temirtau JSC were observed, as a result of which the population of the city of Temirtau experienced a shortage of thermal energy.
The allocated funds for the repair of the main equipment of CHPP-2 do not lead to a decrease in physical wear and tear and accidents. Average wear on the main equipment of CHPP-2 is 77%.
During the heating season, 5 boilers need to work, 1 boiler must be in reserve.
As a result of a decrease in the thermal capacity of the power plant, consumers in Temirtau experienced a heat shortage for 2 days.
On this fact, the territorial department of the Committee for Atomic and Energy Supervision and Control in the Karaganda region in the period from March 10 to March 25 of this year. an unscheduled check was carried out in respect of CHPP-2 of ArcelorMittal Temirtau JSC for compliance with the requirements of regulatory legal acts of the Republic of Kazakhstan in the field of electric power industry. Based on the results of the inspection, violations of the requirements for the operation of boilers and buildings of the boiler shop were revealed.
There are questions about financing repair work and the purchase of fuel for the Kentauservice State Enterprise. Repair work at CHPP-5 and heating networks in Kentau is planned for a total amount of 1 billion 980.0 million tenge, and 1 billion 273 million tenge is also required for the purchase of fuel for the next heating season.
The Akimat of the Turkistan region needs to timely ensure the allocation of funds for the preparation of the Kentauservice GKP for the next heating season.
In general, preparations for the upcoming heating season are being carried out in an orderly manner.
In accordance with the schedule of repairs of the main equipment of power plants of the Unified Electric Power System approved by the system operator, including it is planned to repair 8 power units, 48 boilers, 49 turbines. At various stages, repair work is being carried out at 4 power units, 13 turbines and 15 boilers. Repair work has been completed on 4 boilers.
In 2021, overhaul repairs of power lines with a total length of 20,458 km, 441 substations, 4,315 distribution points and transformer substations are planned on electrical networks.
Based on the results of the heating season 2020-2021 it is necessary:
“The Ministry of Energy, together with local executive bodies, continues to work to control the preparation of energy companies for the upcoming heating season,” the head of the Ministry of Energy of the Republic of Kazakhstan concluded.
As the Minister of Industry and Infrastructure Development Beibut Atamkulov noted speaking at the meeting, the heating season of 2020-2021 was stable.
“The supply of coal to the population and the household sector was under the constant control of the ministry. There was no coal shortage,” Atamkulov reported.
According to the ministry, over the past heating season there were 121 technological violations, of which:
- autonomous boiler houses — 4
- heat supply networks — 34
- water supply networks — 83
The largest amounts of violations were found in Almaty and Nur-Sultan cities, as well as in Akmola, East Kazakhstan and Karaganda regions.
All violations were eliminated within the standard time frame, heat supply and water supply were restored.
For the upcoming heating season 2021-2022 it is necessary to prepare more than 65 thousand units. objects of the social sphere (these are objects of health care, education, residential buildings), 11 thousand units autonomous boiler plants and 19 thousand km of engineering networks.
For the purpose of timely and high-quality preparation for the upcoming heating season, the regions need:
1) by June 1, 2021, to approve an action plan for the preparation of housing and communal services, housing and social facilities;
2) until Sep. 1, 2021, to ensure 100% readiness of educational facilities;
3) by Oct. 15, 2021:
- to ensure full readiness of all objects of housing and communal services, housing, health care and social sphere;
- complete the removal of autonomous heating systems installed in violation of construction norms;
- to complete the preparation for the heating season of the engineering infrastructure system on time;
- to provide a standard fuel supply for autonomous boiler houses.
As a result of active actions of local executive bodies, coal mining companies and suppliers, coal was supplied to all regions in a timely manner for the utilities sector and the population.
At the end of the season, the volume of coal consumption amounted to about 10 million tons, of which about 2.8 million tons for the utilities sector, 7.2 million tons for the population.
Coal availability was 100%.
“In order to prepare for the next heating season, local executive bodies need to form and provide the demand for coal for public utilities and the population for 2021-2022 by July 1 with a monthly breakdown,” noted Atamkulov.
Also, during the heating season, it is necessary:
- to deliver coal in advance with a reserve volume to prevent agiotage;
- to carry out explanatory work on the points of sale of coal.
“In general, the preparatory work for the upcoming heating season is being actively carried out and a shortage of coal is not expected,” Atamkulov assured.
According to the minister, monitoring of the passage and preparation of the heating season is under the special control of the ministry and will continue as usual.
In his report, Akim of the Karaganda region Zheniss Kassymbek noted that in general the autumn-winter period in the region was stable, with the exception of some technological violations that occurred at energy sources.
- Feb. 25, 2021, 3 boilers stopped at once at CHPP-2, which led to a deviation of the temperature regime and this affected the quality of heat supply to consumers in Temirtau (the temperature in the apartments dropped from 25 °C to 13 °C);
- On Dec. 13, 2020, at GRES-2 Topar of Kazakhmys Energy LLP of the Abay region, there was a rupture of the 2nd branch of the steam pipeline of boiler No. 14. But this fact did not affect the quality of heat supply to consumers;
- there was also a decrease in parameters on the M1 main heating network of the city of Karaganda due to the lack of thermal insulation.
In all cases, emergencies were eliminated within 2 days.
During the heating season, 191 failures of the 2nd degree were recorded at the energy sources of the region, which is 11% lower than in the previous period.
“Having analyzed the past heating season, taking into account the existing problematic issues, we have developed measures to prepare for the next autumn-winter period. The main attention is focused on the repair campaign of thermal power plants, heating and electric networks, preparation of multi-storey housing stock and completion of new power facilities under construction,” said Kassymbek.
It is planned to allocate 69 billion tenge for the repair campaign in the region, which is 18.5 billion tenge more than last year.
The plan provides for the repair of 26 boilers and 15 turbines at 8 energy sources in the amount of 21.1 billion tenge.
The following will be prepared:
- 72 boiler houses, 693 autonomous heating systems;
- 115 km of heating, about 3,300 km of electrical, 310 km of water supply and sewerage networks;
- about 7 thousand multi-storey residential buildings, 1,350 social facilities.
All stations have signed contracts for the supply of coal and are already delivering it to coal warehouses. More than 4 million tons of coal will be imported for the coming autumn-winter period.
Currently, a repair campaign has been launched. Some stations are already undergoing scheduled overhauls of the main and auxiliary equipment.
The akim also clarified the situation regarding the work of CHPP-2, ArcelorMittal Temirtau.
According to the akim, since 2019, the construction of a new boiler No. 7 has begun at CHPP-2. Now the project is being actively implemented.
A roadmap has been developed for the resumption of construction of the boiler and preparation for the heating period of the entire station.
ArcelorMittal Temirtau announced a tender to identify contractors for boiler installation and building repairs. The conclusion of both contracts is scheduled for the end of May 2021.
Commissioning is expected by the heating season 2022-2023.
