Double Impact: Steam and Gas to Cement the Energy Balance of the Nation
Uzbekistan keeps upgrading its generating capacities deemed as a kind of circulatory system of the real economy sector. Combined cycle plants are of special priority as the latest trend in modern science and engineering. For instance, gas technology has been the most popular kind of the global energy over the last two decades. Today, it accounts for two-thirds of all new generating capacities.
According to experts, the global development of the power system in the coming decades will be built on the combined cycle. This is primarily conditioned by high efficiency of combined-cycle plants (CCP) unlike the conventional thermal power plants (TPP), since CCPs use the energy of the fuel burned twice - first in the gas turbine, and then in the thermal one. Thermal power plants operate on steam cycle alone.
In Uzbekistan, thermal power plants produce more than 84% of all electricity, which suggests that their modernization is not just a strategic goal, but a vital necessity. Therefore, the integrated introduction of modern combined-cycle technologies in TPPs has been underway in different regions of the country for the past two decades. That would compensate the withdrawn power capacities and stabilize the supplies to the industry and the general public.
Such projects are extremely complicated and costly. Even prosperous states are not able to afford several major projects at a time, particularly in the context of global economic instability, when the industrial demand for electricity is falling. Meanwhile, Uzbekistan stands up against the trend.
Domestic experts have elaborated an ambitious program of developing generating capacities, envisaging both modernization of existing plants and construction of new ones with the latest technological solutions. The projects are partnered by the world’s leading engineering manufacturers and international credit and financial institutions.
Asian Development Bank has been a flagship in this cooperation. For example, in mid-2014, the bank’s Board of Directors approved a $300 million loan for Uzbekistan for the construction of two combined cycle power plants with a capacity of 230-280 MW at Takhiatash TPP. The government entrusted Uzbekenergo to work out a feasibility study for the project by late January 2015.
Introduction of an automated system of commercial electric power accounting is another interesting joint project, envisaging the installation of about five million of cutting-edge electronic meters in all regions of the country.
