Nachtigal Hydro Power Project : Surging Ahead: Cameroon’s Green Power Generation


As demand for electricity shifts from a population’s ‘want’ to a people’s ‘right and need’, the central African nation of Cameroon is firmly staying ahead of the curve. By the close of 2024, its Nachtigal Hydro Power Project will be in full service, providing 30% of the country’s power.

The project - the most important Sub-Saharan Africa’s public-private partnership under construction in the energy sector - will have a total installed capacity of 420 MW driven by seven generators with an electric power unit of 60 MW. It lies at the heart of a vibrant and forward-looking French and English-speaking population of about 30 million people 

Renowned as ‘Africa in Miniature’ due to its geographical variety of desert plains to the north and tropical rainforests in the south, Cameroon is also a country undergoing major transformation with multi-million-dollar infrastructure programs.

One of the most important is Nachtigal. The facility achieved a significant milestone in June 2024 by  commissioning its first turbine unit, thus injecting 60MW to Cameroon’s Southern Interconnected Grid.   

Energy and Water Resources Minister Gaston Eloundou Essomba said the scheme represents a crucial step in Cameroon’s efforts to enhance energy security, stimulate economic development, and foster regional cooperation in electricity production and distribution. 

Additionally, plans to export electricity to neighbouring Chad by 2027 through the Cameroon-Chad Power Grid Interconnection Project will further demonstrate the potential for regional cooperation and economic benefits.


Milestones on the Road to Completion
Since its inception in 2016, NHPC has achieved significant milestones. Financial closure was secured by December 2018, paving the way for construction to begin in February 2019. Fast forward to May 2024, the project successfully injected its first megawatt-hour into the grid, and by June 2024, the first 60 MW unit was commissioned. The journey is ongoing, with the remaining units set to come online in the coming months.

At its peak, the project employed more than 3,500 workers, predominantly Cameroonians, emphasizing local involvement and capacity building. These efforts are not just about construction; they are about creating a sustainable and empowered community around the project site.

 

 

A Symphony of Partnerships


The Nachtigal project is a testament to the power of collaboration. The State of Cameroon is a key institutional partner, ensuring alignment with national goals. The financial structure includes shareholders such as EDF (40%), IFC (20%), the State of Cameroon (15%), Africa50 (15%), and STOA (10%), alongside a consortium of 15 lenders, including local banks.

Technical partners are integral to the project's success. Contractors manage construction across various domains, while EDF provides engineering oversight. Key partners like SONATREL, EDC, and ENEO ensure seamless transmission and distribution of the generated power.

Like all major infrastructure projects, the Nachtigal Hydro Power Project has leveraged partnerships at all levels with both international and local entities that have the capacity and expertise to manage large-scale undertakings. Example of such contributors  include BESIX, Elecnor Cameroun, SGS, Bouygues Energies & Services, Group Holcim's Cimencam, and Alucam just to mention a few. 

  SGS has provided essential inspection and certification services, ensuring compliance with international standards. BESIX has managed substantial civil engineering tasks, demonstrating their capability in large-scale construction.

Elecnor Cameroun has been responsible for handling the electrical infrastructure, ensuring that the project's power distribution is efficient and reliable. 

 

Engineering Marvels and Innovations
Nachtigal’s technical specifications are impressive. The facility includes a 28 million m³ reservoir covering 421 hectares, a 1,380-meter long, 14-meter high main dam, a 3.3 km canal, and a plant with seven generating units producing 420 MW. Additionally, the project features an energy evacuation substation and a 50 km long 225 kV transmission line.

Innovations are at the heart of Nachtigal. Advanced technologies like high-tech beams for concrete laying and a labyrinth spillway on the main dam enhance efficiency and safety. These engineering marvels ensure that Nachtigal operates at the highest standards of hydraulic safety and performance.

Commitment to Sustainability and Social Responsibility
NHPC’s commitment to environmental, social, and governance (ESG) principles is unwavering. Comprehensive environmental and social studies were conducted ahead of construction, resulting in a detailed Environmental and Social Management Plan (ESMP). This plan includes compensatory measures for affected communities and environmental impacts.

Environmental protection strategies are robust, involving compensation for key species and continuous monitoring. The project also supports the Mpem and Djim National Park and implements an archaeological resource protection program, highlighting its dedication to preserving biodiversity and cultural heritage.

Economic and Social Impact
The socio-economic benefits of the Nachtigal project are far-reaching and multifaceted. The project has been a significant driver of job creation, providing employment to thousands of Cameroonians during its construction phase. This has not only injected much-needed income into local economies but also facilitated skills transfer and capacity building among the local workforce.

Moreover, NHPC's commitment to improving local infrastructure is evident. The construction of 44 boreholes has provided clean water to over 10,000 residents in 27 villages, significantly improving their quality of life. Educational and healthcare facilities have also seen substantial investments. New classrooms and maternity wards have been built, while existing structures, like the main building of the Batchenga Medical Center, have been renovated. Health campaigns addressing issues such as ophthalmology and onchocerciasis have been initiated, further enhancing community well-being.

In the long term, the availability of reliable electricity will catalyze economic activities across various sectors. Industries, especially those in manufacturing and services, will benefit from the stable power supply, leading to increased productivity and economic growth. The project is expected to spur local businesses, attract foreign investment, and create a more conducive environment for entrepreneurship.

Overcoming Challenges
As with any major project, Nachtigal faced its share of challenges, each met with resilience and innovative solutions. The Covid-19 pandemic posed significant disruptions, particularly in international trade and the flow of goods and people. Despite these hurdles, construction never ceased, thanks to the adaptability and dedication of the NHPC team and their partners.

In addressing these challenges, NHPC leveraged strong institutional, financial, and technical partnerships. Strategies were implemented to ensure the health and safety of workers, maintain supply chains, and adapt work schedules to new realities. This unwavering commitment to progress amidst adversity highlights the project’s robust planning and management capabilities.

Financial Health and Future Prospects
With a project cost of approximately €1.2 billion (XAF 800 billion), the Nachtigal Hydro Power Project is a flagship Public-Private Partnership in Sub-Saharan Africa’s energy sector. Rigorous financial oversight ensures the proper implementation of funds, contributing to the project’s financial health and stability.

Looking ahead, NHPC aims to be a cornerstone in Cameroon’s sustainable development, providing abundant and affordable electricity. Potential future expansions could further enhance the facility’s capacity, reinforcing Cameroon’s energy security and supporting long-term economic growth.
