The Sendje HPP is a hydroelectric power plant under construction in the mainland region of Equatorial Guinea below the Djibloho HPP on the Wele River (it originates in Gabon and, crossing the territory of Equatorial Guinea, flows into the Gulf of Guinea). Upon completion, the installed capacity of the hydropower plant (200 MW) will be the largest among all the country's generating capacity, and the concrete dam (63.0 m) will be the highest among the dams in Equatorial Guinea.

The construction of the Sendje HPP is carried out by DUGLAS ALLIANCE LTD. commissioned by the government of Equatorial Guinea.

Location and structure of buildings
The construction site is located 30 km south of the capital of the continental region of the city of Bata and 20 km east of the town of Mbini located at the mouth of the Wele River. The layout of the hydroelectric complex is derivational. As part of the project, the river will be blocked by a concrete gravity dam 63.0 meters high; in addition, when creating a pressure front for water in the reservoir, four auxiliary earthen dams up to 20 meters high will be built. The energy circuit is represented by the inlet channel to the water intake, water intake, pressure metal conduits with an internal diameter of 5.0 m, the building of hydroelectric power stations and the outlet channel. Radial-axial turbines (Francis) are to be installed in the building of the hydroelectric station - 4 pcs. The electricity supply to the system will be carried out through 220 kV GIS..

Main characteristics of the project

 * Installed capacity – 200 MW, 4 hydraulic units with a unit capacity of 50 MW.
 * Power output voltage – 220 kV.
 * Average output per year – 1,402 million kWh.
 * Estimated pressure – 67.5 m.
 * Reservoir:
 * Reservoir mirror area – 21.57 km2.
 * Normal reservoir retaining level – 88.0 m.
 * Useful volume of the reservoir – 60.2 million m3.

Connection with the power system is carried out through power transmission lines, designed for a voltage of 230 kV.

Main stages of the project
The project execution for the construction of hydropower plant began in 2012. The official opening of the construction by the President of the Republic of Equatorial Guinea with the participation of members of the government, parliament and public delegations took place in February 2012.

In autumn 2015, the Wele River was dammed.

As of March 2018, the launch of the Sendje HPP is scheduled within 31 months.
