Outline of GHG Mitigation Activity

The purpose of this project is to reduce CO2 emission through the introduction of amorphous high efficiency transformers instead of transformers with silicon steel core in power grid.

1,307 transformers in total are introduced to Electricite Du Laos.

The use of amorphous alloy in the amorphous transformer’s iron core leads to improvement of electrical characteristics and significantly reduces non-load losses (standby electricity).

Expected GHG Emission Reductions

2,109 tCO2-eq./year

= (No load losses of the reference transformer – No load losses of the project transformer) x

(1 – Blackout rate during the project period) x CO2 emission factor of the grid

Site of JCM Project

Amorphous high efficiency transformers are introduced into all regions in Laos (17 provinces and one city)
