NEDO and the government of Uzbekistan signed a memorandum of understanding on October 14, 2016, to jointly implement a demonstration project on high-efficiency gas turbine cogeneration systems in Fergana, Uzbekistan.
In the project, small- to medium-sized cogeneration systems will be installed at a heat supply plant and a combined heat and power plant respectively. The heat supply plant will then be able to produce electric power, and the generation efficiency of the combined heat and power plant will be improved, thereby resulting in an energy saving of 38% and ensuring a stable supply of power and heat.
In Uzbekistan, ten thermal power plants, including three combined heat and power plants, produce nearly all of the country’s electric power. However, many of these plants were constructed during the Soviet era, and their performance and reliability are declining. Ensuring a stable power supply is therefore a pressing issue as power demand is increasing due to the country’s recent economic growth.
For this reason, the government of Uzbekistan is planning to modernize existing power plants and convert more than 2,000 domestic heat supply plants of various sizes into combined heat and power plants. This is expected to improve the country’s power generation capacity and decentralize power sources.
Against this backdrop, NEDO and the government of Uzbekistan agreed to jointly implement a demonstration project in Fergana with the aim of promoting small- to medium-sized high-efficiency gas turbine cogeneration systems in Uzbekistan. The two sides concluded a memorandum of understanding (MOU) for the project on October 14, 2016.
NEDO will entrust its work related to the project to Kawasaki Heavy Industries, Ltd. and Marubeni Utility Services, Ltd. In the project, a high-efficiency gas turbine cogeneration system with a power output of 17 MW will be installed at the Fergana Combined Heat and Power Plant. The system is designed to improve power generation efficiency and reutilize exhaust heat from a gas turbine. The same system with a power output of 7 MW will also be installed at the Fergana RK-3 Heat Supply Plant to convert the plant into a combined heat and power plant. Power generated at the plant will then be supplied to neighboring areas where power is currently transmitted from a large distant power plant, thereby reducing transmission loss. As a result, each system is expected to use 38% less energy than conventional systems and the project will help ensure a stable supply of power and heat.
Based on the project results, NEDO will strive to disseminate gas turbine cogeneration systems throughout Uzbekistan, and it will also consider expanding dissemination activities to surrounding countries where a number of heat supply plants are in use.
