US developer Hydromine signed a letter of intent with the government and Eneo on 5 July for the development of the long-mooted Grand Eweng hydropower project. The parties will work together to finalise the terms of a power purchase agreement between the project company and the utility. The letter of intent also sets out the framework for development of the project on a build, own, operate and transfer model. Construction of the project, on the Sanaga River between Yaoundé and Douala in the eastern Littoral region, is expected to start within three years, with electricity generation starting in seven years.
