The Tététou Project involves the development of two cascading hydropower schemes downstream of the existing Nangbéto Dam. The upstream plant (45.4 MW, 22.3 m dam, 128.9 GWh per year) and downstream plant (14.3 MW, 22.6 m dam, 69.2 GWh per year) would provide a total installed capacity of 59.7 MW and generate an estimated 198.1 GWh annually. The configuration combines flexible peak generation upstream with more consistent downstream generation and flow regulation. The project also includes associated power evacuation infrastructure and offers potential synergies with solar generation through the optimisation of shared grid infrastructure.
Project overview
Investment opportunity
The project offers a potential long-term infrastructure investment opportunity in renewable electricity generation. The structure envisaged in the submission is a public-private partnership with an independent power producer (IPP), supported by a proposed 25-year concession and a long-term power purchase agreement with the utility. Investors may participate through project equity, long-term debt, engineering and construction partnerships, or financing and risk-mitigation support from development finance institutions. The estimated output of 198.1 GWh per year and the role of hydropower in complementing variable solar generation form the project's core strategic rationale. However, tariff and power purchase agreement terms, capital costs, financing arrangements, risk allocation, hydrological assumptions, environmental and social safeguards, and financial return indicators will require further validation before the opportunity can be considered fully bankable.

Structuring & preparation
Current status / progress to date
Completed: Pre-feasibility, technical and financial feasibility studies, including the techno-economic study and APS (Artelia, 2021). Ongoing: Environmental and Social Impact Assessment (ESIA). Next steps: Finalise financing and contractual arrangements, obtain regulatory approvals and launch procurement. The project has been identified as a priority PPP opportunity to be developed under an Independent Power Producer (IPP) model.

Expected impact
Jobs created / supported
Indicative planning estimates suggest approximately 800 direct jobs during construction, including around 100 permanent operation and maintenance positions, and 1,500 indirect jobs through local suppliers, transport, logistics, services, subcontracting and related economic activities. These figures will require validation through the detailed feasibility study and contractor workforce planning.
Economic & development benefits
- Adds 59.7 MW of domestic renewable energy generation capacity and produces approximately 198.1 GWh of electricity annually
- Strengthens energy security and reduces exposure to imported electricity
- Supports industrialisation and investment by improving electricity availability for businesses, SMEs and productive activities
- Contributes to rural development in approximately 20 nearby communities through electrification, irrigation and drinking water infrastructure
- Supports agricultural productivity, local enterprise development and economic opportunities linked to construction, operation and improved access to reliable electricity
- Contributes to Togo's renewable energy and electricity access objectives and supports the expansion of modern energy services
Climate & resilience benefits
- Generates approximately 198.1 GWh of renewable electricity annually, displacing more carbon-intensive sources of generation
- Potentially avoids approximately 29,700-89,100 tCO₂e annually based on APS emissions reduction estimates
- Supports long-term greenhouse gas emissions reductions through renewable hydropower generation
- Improves the regulation of seasonal water flows and contributes to flood management, subject to detailed hydrological assessment
- Strengthens downstream climate resilience by helping to manage flood risks affecting communities, agricultural activities and infrastructure
- Supports water resource management and adaptation to climate variability through the maintenance of minimum water releases during dry periods, subject to operating rules and environmental flow requirements
