An explosion has struck the Naira Zungeru Hydroelectricity Dam in Niger state, raising the potential of a blackout.

The dam is the fourth in the state, following Jebba, Kainji, and Shiroro; however, the federal government has yet to officially commission it.

According to Vanguard, the explosion occurred in the early hours of today.

The true reason for the explosion is still unknown.

According to a reliable source, several workers on duty sustained varying degrees of injury and are being treated at nearby hospitals. Those badly injured were transferred to Minna, the state capital, for further medical assistance.

“We saw a foreigner,(Chinese) who is a worker who had severe injuries being ferried to Minna for further medical attention but we cannot say the exact number of staff injured but they are many,” the source added.

Besides the human injuries, the explosion was said to have affected some installations at the Dam. The implication of the explosion on power supply generally across the country is not yet known.
