The Rwanda Energy Group (REG) says it is still investigating the cause of a power blackout that plunged many parts of the country into darkness on Tuesday evening, calling on the public to remain patient as technicians work to establish what went wrong.

The outage occurred on Tuesday, February 3, 2026, and lasted for more than an hour in several areas nationwide, adding to a series of electricity disruptions that have been reported since the end of last year.

In an interview with KIGALIINFO, REG Spokesperson Geoffrey Zawadi apologized to customers for the inconvenience, stressing that the utility remains committed to providing reliable electricity despite ongoing technical challenges.

“We regret the disruption experienced by our customers,” Zawadi said. “REG continues to invest significant effort and resources to ensure a stable power supply across the country, and further measures are still being implemented to address these recurring challenges.”

He explained that power outages are sometimes unavoidable and can occur due to faults at different stages of the electricity supply chain, including generation plants, transmission infrastructure, or local distribution networks.

According to Zawadi, teams of technicians operate on a 24-hour basis to respond to such incidents, while investigations are underway to determine the exact source of Tuesday’s blackout.

“At this stage, we cannot yet confirm where the fault originated. Our technical teams are still analyzing the system to identify the root cause,” he said.

Zawadi also noted that REG has not ruled out the possibility that the disruption may be linked to regional power facilities jointly operated with neighboring countries, though no conclusion has yet been reached.

While acknowledging that electricity interruptions are a reality in power systems worldwide, he encouraged institutions and businesses whose operations are highly dependent on electricity to invest in alternative energy solutions such as solar systems or backup generators. Households, he added, can also reduce the impact of outages by using rechargeable power-storage equipment.
