Infrastructure Maintenance and Storms Cause Widespread Power Outages in Ghana and Arizona
The Electricity Company of Ghana and Arizona utilities have reported widespread power disruptions affecting thousands of customers across two continents. While Ghana's outages stem from a four-day planned infrastructure upgrade, Arizona's West Valley is recovering from weather-induced damage.
Key takeaways
- The Electricity Company of Ghana is conducting planned maintenance from August 10–13 to improve infrastructure reliability.
- Monsoon storms in Arizona have left 37,000 residents without power due to downed poles and fallen trees.
- Ghanaian residents in Tema, Kumasi, and Accra East face daily service interruptions lasting up to nine hours.
What Happened
Electricity providers in Ghana and the United States reported significant service interruptions on August 9 and 10, 2026. In Ghana, the Electricity Company of Ghana (ECG) initiated a series of planned maintenance works across the Tema, Ashanti, and Accra regions. The utility stated these interruptions are necessary for infrastructure upgrades and service reliability improvements.
Simultaneously, in Phoenix, Arizona, severe monsoon storms caused unplanned outages for approximately 37,000 customers. Salt River Project and Arizona Public Service reported that the West Valley was hardest hit following heavy rain, strong winds, and fallen utility poles.
Key Facts
- Ghana (Planned): Maintenance schedules run from August 10 to August 13, 2026, typically between 8:30 am and 5:00 pm.
- Ghana (Locations): Affected areas include Sakumono and Devtraco in Tema; Trede and Offinso in the Ashanti Region; and Teiman, Labone, and Madina in the Accra East Region.
- Arizona (Unplanned): 37,000 customers lost power as of Sunday night, August 9, due to weather damage.

- Weather Conditions: The National Weather Service issued flash flood and dust storm warnings for Maricopa and Pinal counties during the Arizona event.
Background
The planned outages in Ghana follow a period of persistent power fluctuations. In April 2026, ECG management issued a public apology for weekly power cuts that have caused commercial and residential disruptions. The current four-day schedule is presented as a strategic effort to enhance the grid's reliability through proactive maintenance.
What Happens Next
In Ghana, maintenance will conclude on Thursday, August 13, with the final phase affecting the Achimota School area. Residents have been advised to make alternative arrangements during the 9-hour daily windows. In Arizona, utility crews are working to restore power as the National Weather Service monitors lingering storm risks, including potential dust walls moving north from Pinal County.
