• Electricity Company of Ghana will upgrade the Teshie-Nungua Primary Substation transformer from 20/26MVA to 30/39MVA starting April 27–30, 2026.

• The upgrade will cause scheduled, rotational power outages in Teshie and Nungua areas, lasting about 5–6 hours per group.

• The project is aimed at improving capacity, reducing outages, and stabilising voltage in the area.

Residents of Teshie and Nungua are set to experience planned and rotational power interruptions beginning Monday, April 27, 2026, as the Electricity Company of Ghana (ECG) undertakes a major transformer upgrade project aimed at improving long-term power supply reliability in the area.
