Five Year Generation Investment Plans Puts Hydro Plants at Capacities seen 30+ years ago.

In October 2013, Kainji PLC & Shiroro PLC formerly part of GENCO was sold to Mainstream Energy Solutions a consortium that comprises of seven corporate entities from across various sectors of Nigeria. This was part of an effort to complete the privatization of the generation companies formerly held by the Power Holding Company of Nigeria (PHCN). Kainji PLC consists of two hydro plants namely Kainji Hydro and Jebb Hydro located in the Kainji and Jebba regions of Northern Nigeria.

The initial installed generation capacities of both the Kainji and Jebba hydro plants are 760MW and 578MW respectively. This is a combined total of about 1338MW (1.3GW).  However, as of today, Kainji and Jebba hydroelectric plants have an operating generation capacity of only 110MW and 450MW respectively which translates to a combined total operating capacity of about 560MW. Today, Kainji and Jebba plants operate at only 14% and 78% of their initial respective installed capacities. This works out to a total operating generation capacity that is approximately 42% of the combined initial installed capacity of these plants.

In an article released in the Punch [Dayo Oketola, November 21, 2103] titled “Mainstream increases Jebba Plant’s Capacity to 450MW”, Mainstream stated that the agreed mandate in the concession agreement is that within five (5) years, the company would recover the lost capacities of both the Kainji and Jebba power plants.  This total combined installed capacity in the referenced article above was stated to be 1500MW but from my analysis above it is actually 1338MW. The approximately 200MW difference could be from additional 200MW unutilized design capacity at the Kainji Hydro plant. This plant was designed for a total of 12 turbines which translates to a total installed capacity of 960MW. However, only 8 turbines were installed at the Kainji plant translating to an initial installed generation capacity of 760MW at this plant.

If this strategy to recover the lost capacity at these plants is successful, this would put us back to the generation capacity of 1963 when the Kainji plant was installed and 1984 when the Jebba plant was added to the power system. Mainstream’s strategy which has been agreed with our leaders would take us 5 years to fully execute and implement but will only get these major hydro plants to the installed generation capacities seen 30+ years ago. It should be noted that there could also be additional 200MW supply if unused available design capacity at the Kainji plant is utilized within the next 5 years.

I applaud Mainstream for their investment in the acquired asset. This was expected and is a true measure of the value of privatization in the generation sector. Hydroelectric assets require no fossil fuels and this drastically reduces the cost of operating these plants. The faster Mainstream energy invests in maximizing the generation output from both Kainji and Jebba hydro plants, the faster they can generate revenues to recover their cost of acquisition and investments. What bothers me as a Nigerian is that we have to wait 5 years to have generation capacities similar to what was present at these plants over 30 years ago.

Nigeria is in this position today because of huge unnecessary neglect by our leaders in the power sector over many years. This neglect is part of the reason we have become a nation that runs predominantly on diesel generators. This neglect has cost Nigerians to lose billions of dollars of potential revenue/GDP from foreign and local investments. This neglect has stunted our growth across multiple sectors. How did Nigerians let this happen? Why do we have to wait for 5 years to enjoy the availability of the generation capacity and clean energy that was supplied from these hydro plants over 30 years ago? How did Nigerians let this get to such an embarrassing state? How can a country estimated to have requirements of over 100GW of supply based on its population have just under 5GW? How can we fix it? When will we fix this? Nigerians, let us work together and fix this!

From the analysis above, it takes no genius to know that we are not going to achieve anywhere close to 40GW in 2020 at the pace we are moving. There have been no announcement for any mega power projects similar in magnitude to the ones discussed in this article that will be required to meet the 40GW target for 2020. It should also be clear that even the 10,000MW planned for 2014 is also far from our reach given the limitation on the transmission network and generation supply.

Fifty One (51) Hydroelectric Plants similar in size to Kainji Dam needed to meet 2020's 40MW Targets

The “Road Map for Power Sector Reform” set a target for Nigeria to attain a generation supply of 40GW by 2020. As mentioned in my previous article “Nigeria to make International History if Generation Supply grows to 10GW (100% growth) by 2014”, this corresponds to an annual growth rate of 37% which is an unrealistic growth rate when compared to annual growth rates in power sectors around the world.


To date, Nigeria has only been able to reach a peak generation supply of 4.5GW and this was achieved in December 2012. Since 2012, Nigeria has not been able to attain this peak generation supply due to unreliable transmission network, over loaded and aging equipment etc.

To bridge the generation supply gap to meet the 40MW supply by 2020, Nigeria would have to install approximately 35.5GW of generation capacity along with the corresponding expansion of the transmission grid in the next 7 years. This is approximately nine times the existing generation and transmission supply in the country today.

To put this in perspective, If Nigeria is to achieve the 40GW goal set by the Road Map by 2020, we would need approximately fifty one (51) hydroelectric dams with installed capacity similar to Kainji Dams to be constructed and put in service within the next 7 years. The Kanji Power plant is the largest hydroelectric power plant that has been constructed and commissioned in Nigeria. This Hydro plant was put into services in 1968 with a total installed capacity of 760MW (0.7GW). Since 1968, there has been no other hydroelectric generation facility of this size installed in Nigeria.

To illustrate even further, the Three Gorges Dam in China is the largest Hydro facility in the world. The Three Georges hydro plant has a total installed capacity of 22.5 GW. To meet the targets set out in “The Road Map for Power Sector Reform”, Nigeria would have to install approx. two hydro facilities each the size of the Three Gorges Dam within the next 7 years. It should be noted that this Hydro plant had a price tag of $21 billion and took a total of 18 years to construct.

One might ask that we could meet the 40MW generation target by installing natural gas or coal plants given the environmental concerns, high cost and long durations to construct a hydroelectric dam. Well, the largest natural gas generation plant in the world is the Surgut-2 plant in Russia and this plant has a total installed capacity of 5.6 GW. Also, the largest coal generation plant in the world is the Taichung Power Plant constructed in Taiwan. This coal plant has a total installed capacity of approximately 5.8GW.

From above, it is clear that if Nigeria plans to install 35.5GW of power within the next 7 years to meet the targets set out in the road map using natural gas or coal plants, we would need construct and install a minimum of the six of world’s largest natural gas or coal plants within the next seven years.

When put into perspective by comparing to the world’s largest power plants, it seems impractical to achieve these goals set out in the road maps. Nevertheless, Nigeria’s power problem needs to be fixed. If we really have the intention to fix the problems in the Nigerian power sector in our life time, we would need multiple Mega projects like the Three Gorges Dam, the Surgut-2 plant or the Taichung Power Plant to bridge the power shortage gap. A generation supply of 40GW is not our final GW target as Nigeria’s power requirements today based on total population is estimated in excess of 100GW.

Our leaders need put in place serious plans for approval of critical Mega projects that will add large amounts of GW supply to the grid. The approval of single generation plants with installed capacities of less than 1 GW (example the 0.7GW Zengeru dam approved this year) will not cut it unless the goal is to have multiple similar sized projects approved around the same time frame. Initiating one-two small generation plants of this size a year will not even bring us close to our target in the next decade. It should be noted that mega transmission projects would also be required on the transmission grid to accommodate for the increased generation supply to the grid.

Nations like China, Taiwan and Russia were faced with planning growing their power sector to meet their consumer demands. These countries proved their commitment to their people’s growth and development by stepping up to the plate to design and construct major projects to meet the increasing power demands of their nation. Nigeria is expected to make a similar statement and commitment to its people by planning and executing projects of equal or greater magnitude to meet the embarrassing power shortfall in the country.
