The Grand Eweng Power Station is a hydroelectric power project currently under development in Cameroon that will be constructed on the lower Sanaga River upstream from the Song Loulou Hydroelectric Power Station. The proposed Grand Eweng Hydroelectric Power Station consists of a dam and reservoir with a hydroelectric facility with an installed power of about 1,000 MW in the first phase to be financed as an independent power producer.

The power station will be located at the Grand Eweng site, on the Sanaga River, approximately 8 kilometres (5 mi) by road upstream from the town of Sackbayeme and 100 kilometres (60 mi) equidistant midway between Yaoundé and Douala, located in the eastern Littoral Region near the villages of Log Pagal and Kahn, bordering the western Centre Region. The power station will be approximately 25 km upstream of the existing Song Loulou Hydroelectric Power Station. The coordinates of the Grand Eweng site are: 4°04’22”N, 10°37’48”E.
