US power company AES Corporation has reportedly said that a financing shortfall will delay construction of the Bujagali dam in Uganda, only two months after the company won World Bank backing for the US$500M project.

The delay in the project comes after AES overcame years of protest by environmentalists, who questioned the cost of the dam and its potential to deliver power to one of the world’s poorest nations.

Construction of the dam was originally launched in January 2002 by Ugandan president Yoweri Museveni. It now looks like the project faces a two to four month delay, according to reports from the International Rivers Network.
