A second phase of capacity upgrade works is in progress at the Shashemene 132 kV substation to address the rising demand for electricity in West Arsi Zone and surrounding areas, according to substation officials.

Substation Manager Mr. Mihretu Gizaw said the project focuses on replacing outdated control systems, which have been in operation since 1973 E.C., with modern Gas-Insulated Switchgear (GIS) breakers to improve reliability and ensure uninterrupted power supply.

He noted that previous upgrade works have already modernized the 33 kV and 15 kV control breakers, which are now fully operational.

With electricity demand increasing due to rapid urbanization and economic growth, additional improvements are being undertaken. Civil works for the installation of new 15 kV GIS control breakers under the second phase have reached 60 percent completion.

Mr. Mihretu stated that the ongoing upgrade will enhance the substation’s operational capacity and strengthen the reliability of power supply to communities in the area.

He also indicated that plans are underway to install an additional power transformer to further increase capacity.

Currently, the substation has a total capacity of 60 megawatts, of which 52 megawatts is already in use, reflecting the growing demand for electricity.

The Shashemene substation is equipped with two transformers rated at 50 MVA and 25 MVA, four incoming transmission lines, and multiple outgoing feeders, including one 132 kV, three 33 kV, and nine 15 kV lines.

It provides electricity to several towns, including Adami Tulu, Meki, Warka, Wondo Genet, Arsi Negele, Kofele, and Shashemene, as well as nearby areas.
