Jebba hydropower turbine restoration marks a major comeback for northern Nigeria’s electricity generation, as the 578.4 MW plant resumes full capacity for the first time in over a decade.
Northern Nigeria is celebrating a transformative milestone in its energy history. For the first time in 15 years, the Jebba Hydropower Plant, one of the region’s key electricity sources, has returned to full operational status. This comes after the successful restoration of Turbine Unit 2G6, which had been non-functional since a fire incident in 2009. The move boosts national grid capacity and strengthens Nigeria’s push for energy security and low-carbon development.
Located along the Niger River in Niger State, the Jebba Hydropower Plant is now operating at its full installed capacity of 578.4 megawatts (MW)a vital contribution to Nigeria’s fragile grid, which has struggled with underperformance and inadequate generation for decades.
The journey to full rehabilitation has been complex, costly, and delayed. In 2009, Turbine 2G6 was crippled by fire damage, halting a significant portion of the plant’s output. For years, the unit remained dormant, largely due to bureaucratic bottlenecks, funding gaps, and limited technical capacity.
In 2021, a contract worth over $122 million (₦27.7 billion) was awarded to Mainstream Energy Solutions Ltd (MESL), the plant’s concessionaire, alongside German engineering firm Voith Hydro, to restore the turbine and modernize the plant’s aging systems. Voith brought in specialized equipment and personnel for turbine replacement, generator rewinding, and digital control upgrades. The work also focused on improving dam safety mechanisms and introducing more advanced monitoring systems for long-term performance.
By mid-2025, the restored unit successfully passed its commissioning tests, officially bringing the plant’s sixth turbine online and enabling Jebba to operate at full design capacity for the first time since 2009.
Strategic Role in Nigeria’s Power Grid
Jebba is the second-largest hydropower facility in Nigeria, trailing only the 760 MW Kainji Hydropower Plant, which also lies along the Niger River. Both plants feed directly into the national grid and play a pivotal role in powering key urban and industrial centers in the country.
At 578.4 MW capacity, Jebba contributes around 8–10% of Nigeria’s average daily power generation, according to the Nigerian Electricity System Operator (NESO). This figure fluctuates due to seasonal variations in river flow but still places the plant among the most reliable contributors to base-load electricity.
The restoration of the damaged turbine boosts not only the installed capacity but also system stability. Unlike thermal plants, which rely on gas supply chains that are often disrupted by pipeline vandalism and market distortions, hydroelectric power offers cleaner and more consistent energy, especially during peak water flow periods.
A Win for Renewable Energy and Emission Reduction Goals
The revival of the Jebba plant feeds into Nigeria’s larger climate and energy transition agenda. Under the Energy Transition Plan (ETP) launched in 2022, Nigeria committed to achieving net-zero emissions by 2060 and expanding its renewable energy share significantly.
Hydropower, while often sidelined in global renewable discussions, plays a foundational role in Africa’s green energy roadmap. It is dispatchable, relatively low-cost over time, and aligned with grid expansion efforts. According to the International Renewable Energy Agency (IRENA), Nigeria’s economically feasible hydropower potential exceeds 10,000 MW, of which less than 20% is currently utilized.
The restoration of Jebba therefore represents a practical stride toward reducing reliance on diesel and gas-fired plants, which contribute heavily to the country’s greenhouse gas emissions and strain its forex reserves through fuel imports.
Infrastructure Challenges Still Loom
While the Jebba plant restoration is a step forward, experts caution that Nigeria’s electricity problems are far from solved. The transmission and distribution systems remain weak, with regular breakdowns and low dispatch efficiency.
For instance, even with the additional megawatts from Jebba, the Transmission Company of Nigeria (TCN) may struggle to absorb and distribute the added power due to aging infrastructure, grid instability, and lack of regional balancing mechanisms. Peak electricity demand in Nigeria exceeds 17,000 MW, yet available generation rarely crosses 5,000 MW, indicating a yawning supply-demand gap.
Moreover, long-term sustainability of hydro assets like Jebba depends on water flow management, sediment control, and environmental protection of the Niger Basin. Deforestation, poor dam maintenance, and erratic rainfall linked to climate change could eventually impact the plant’s output.
The successful restoration of the Jebba turbine offers key policy and market lessons:
- Public-Private Collaboration Works: The concessioning of Jebba and Kainji dams to MESL in 2013 under Nigeria’s power privatization program is now bearing fruit. With the right contractual frameworks and investment incentives, private sector involvement can breathe life into neglected assets.
- Local Capacity Building Is Essential: Voith Hydro’s involvement came with technical training for Nigerian engineers and plant operators. Over time, this builds domestic competence and reduces reliance on foreign experts for major repairs.
- Hydropower Needs More Visibility: While solar and wind dominate the renewable energy conversation, hydropower should be promoted as a central pillar of Nigeria’s base-load clean energy strategy, especially given its integration potential with storage and hybrid systems.
- Finance Remains a Bottleneck: Large infrastructure projects like turbine overhauls require substantial upfront funding. Nigeria must continue leveraging international climate finance, development bank loans, and sovereign green bonds to unlock the full hydropower potential.

Beyond energy statistics, the Jebba plant’s full return holds deeper socio economic significance for northern Nigeria. Reliable electricity supply spurs industrialization, job creation, agro-processing, and rural electrification, areas where the North has historically lagged behind the South.
Communities in Niger, Kwara, and Kogi states stand to benefit from better access to electricity, reduced use of polluting generators, and improved economic productivity. This could reduce youth migration and insecurity in a region often plagued by poverty and violence.
