Reconstruction of facilities in 2010-2011

The results of the fulfillment of investment obligations under JSC “Almaty Electric Power Plants”
for 2010-2011.

In accordance with the signed Agreements “On Investment Obligations” with the Ministry of Industry and New Technologies of the Republic of Kazakhstan, AlES JSC carried out measures to replace, upgrade, reconstruct, re-equip existing assets, new construction, as well as maintain the current production level in the amount of 16.3 billion tenge.

As part of the fulfillment of Investment Obligations, the following main activities were carried out:

The development of a feasibility study (feasibility study) for the reconstruction of the HPP Cascade has begun;
development of a feasibility study for the construction of a counter-regulating Kerbulak HPP on the Ili River;
development of a feasibility study for the reconstruction of CHP-1 with conversion to gas and installation of GTU (gas turbine unit);
reconstruction of ash-collecting plants with the installation of emulsifiers on boilers at CHP-2, CHP-3 – allowed to reduce the negative impact on the ecology of the region and reduce the permissible gross emissions of harmful substances (ash) by 5,600 tons per year;
commissioning of cooling towers at CHP-2 and CHP-3 – reduced the gap between installed and available capacity by an average of 120 MW (at CHP-2 by 90 MW, at CHP-3 by 30 MW);
reconstruction of the excitation system of the Kapshagai hydroelectric power plant – allowed to increase the service life of the equipment;
linking the excitation system of hydro generators to the turbine hydraulic control system (GRPM) at Kapshagai HPP allowed to increase the equipment utilization rate;
reconstruction of the pipelines of the idle discharge of the HPP Cascade – allowed for timely discharge of water and to ensure trouble-free operation of the stations;
work on the replacement of 110 kV oil switches with gas-fired ones at CHP-1, CHP-2, CHP-3 has made it possible to increase the reliability of energy supply to electricity consumers;
reconstruction of the gas distribution point of CHP-1 – allowed to increase the reliability of gas supply and the accuracy of fuel metering of the power plant;
the reconstruction of desalination plants at CHP-1, CHP-2, CHP-3 has significantly reduced the amount of impurities in wastewater and reduced the cost of desalinated water by reducing water consumption for own needs and the cost of chemical reagents and ion exchange materials;
the reconstruction of steam pipelines of boilers and turbines, as well as the connecting steam collector at CHP-3, made it possible to replace physically worn–out equipment that had exhausted its park resource;
the introduction of an automated commercial electricity metering system (ASKUE) made it possible to reach a high-quality level of service and optimize energy consumption.
