A. Project description
A.1. Title of the JCM project
A HIGH EFFICIENCY AND LOW LOSS POWER TRANSMISSION AND DISTRIBUTIONSYSTEM IN MONGOLIA
A.2. General description of project and applied technologies and/or measures
The purpose of the proposed JCM project is to stabilize the supply of electricity and reducegreenhouse gas (GHG) emissions through installation of a Japanese transmission line system
employed a low-loss transmission line that will transmit electricity with high efficiency. The
low-loss transmission line has employed the following improvements, which contribute tolow-loss.
(a)
Increase the space factor of the conductor by modifying the formation of thealuminum wire from a circular to a fan-shaped design.
(b)
Reduce the cross-sectional area of the aluminum-clad steel wire, and increase thecross-sectional area of the conductor.
(c)Substitute the galvanized wire with a more conductive material.
(d)
Apply an even-number of layers of aluminum wire.
By incorporating the above four measures, the low-loss transmission line, when compared to aconventional transmission line, can reduce transmission loss by 10 to 15%, and therefore
contributes to a reduction in CO2.
The project proponent will construct a new single-circuit transmission line spanning 159.4km
between the new Oyu Tolgoi (NOT) substation in Ömnögovi province and Tsagaan Suvarga(TS) substation in Dornogovi province located in the southern region of Mongolia.

A.6. Contribution from Japan
The project has been selected as one of the JCM demonstration projects by the New Energyand Industrial Technology Development Organization (NEDO), the largest public management
organization promoting research and development under the Japanese government. Throughthe NEDO's demonstration program, the project obtains financial resources to cover theimplementation cost of the proposed project partially.
Further, the state-of-the-art low-loss transmission line which has been developed in Japan is2

introduced in Mongolia for the first time. Also, Hitachi, Ltd. instructed the Japanesetechnology to Mongolian counterpart, NPTG, and helps NPTG to implement propermonitoring of electricity transmitted.
