Kenya invites investors for geothermal power plants

Fri Nov 5, 2010 1:14am EDT
By Mark Denge

NAIROBI, Nov 5 (Reuters) - Kenya's Geothermal Development Company (GDC) has invited prequalification bids from investors for the development of 400 megawatts (MW) of power from underground steam.

The state-owned company expects to drill 120 wells in the first phase of the project that will contribute about a quarter of the country's current installed power capacity, as east Africa's biggest economy shifts production to green sources.

"The estimated 400 MW Menengai Phase 1 geothermal project including four power plant construction is projected to be completed by 2014," the company said in a statement on Friday.

"GDC will map the first four development blocks, drill exploration, appraisal and production wells and offer the steam to competitively selected investors who will construct the power plants and generate power with the fuel mined from these blocks."

GDC estimates that the project field within Kenya's Rift Valley has a potential of about 1,250 MW.

"The long term plan is to develop 1000 MW within this prospect. However,the current project aims to realise about 400 MW by year 2014, 600MW by 2016 and 1,000MW by 2018."

The GDC has pledges worth $400 million, 40 percent of the amount it needs for a 10-year plan during which it intends to produce 2,000 megawatts (MW) of steam.

The company formed in July 2009 to spearhead exploration of geothermal steam has drilled 25 wells in the Ol Karia field in Kenya's Rift Valley, all of which have been successful. They have steam equivalent of 196 MW.

Kenya's main power producer KenGen (KEGN.NR) is already producing more than 200 MW of electricity from geothermal sources in the Rift Valley, and plans to add 280 MW of geothermal power at a cost of $1.3 billion by 2013.

The East African nation relies heavily on hydroelectric dams for power, which, although cheaper to build compared with geothermal plants, can be inefficient in times of drought.

Another firm said on Friday it planned to generate 60 MW of wind power.

"Aeolus Kenya is in the process of implementing a wind power project to be located to Kinangop Plateau near Magumu, Nyandarua district," an advertisement in the Daily Nation said.

"The project will generate 60 MW of electric power which will be transmitted to Naivasha sub-station for sale to KPLC."

Kenya Power and Lighting (KPLC.NR) is a monopoly electricity distributor in the country.

KenGen is already generating over 5 MW from wind in the outskirts of the capital and another firm, Lake Turkana Wind Power, plans a 300 MW farm in a wind-swept region of northern Kenya.

My only concern with the wind power is the cost, it seems it will be more expensive than the retail prices of electricity.
I would love to have a comparative cost per kilowatthour data between hydro and geo thermal...

Geothermal is way cool. We have loads of capacity for it and we should exploit as much of it as we can before we ever consider nuclear.

Wind farms are nessesary for diversification purposes. The good thing about that is it offeres a different source that does not involve importing petrol when drought strikes again.

Way to go ken gen.

The video is in french



Can't believe this project is finally starting after being allocated money in 2010

So by next year we can expect 400mw in the grid and another 600mw in 2016 :banana:

Had no idea this was advancing well too. Olkaria has been hogging the limelight.

120 wells is no easy job, I wonder how long it will take. I imagine they would start construction of the power plant before they finish drilling to deliver the 400 + 600 megawatts by 2016 as planned.

Guyz I have read several online websites saying that the 105 MW Menengai geothermal powerplant has been constructed and that the construction is complete. Most of these articles seem to be quoting an African development bank article which seems to suggest that construction is complete. AFDB is the main financier of the project. I am very skeptical of these reports because no Kenyan media whatsoever has reported on this. Furthermore some of the articles say that construction started in December of 2019 and that the plant was completed in October of 2020. Is it really possible to construct a geothermal powerplant in 8 months? Is it true? Why is the Kenyan media not reporting on it? It is all very strange and confusing.

Here is the AFDB article








In Kenya, the Menengaï geothermal plant, funded by the African Development Bank, is helping 500,000 households overcome a severe electricity shortage

In six years, Kenya has more than tripled production, from 198 to nearly 672 megawatts (MW), becoming Africa's leading producer of geothermal energy in the process. The commissioning of the Menengaï geothermal power plant enabled the East African country to eliminate its electricity deficit to overcome the severe shortages it experienced in the late 2000s.
The Menengaï Geothermal Development Project, with $108 million in funding from the African Development Bank, has added 105 MW of geothermal production capacity to the national electricity grid, with participation by three private companies.
For the implementation of the plant, 50 wells were targeted to generate enough steam to produce more than 100 MW. Some 49 wells had been drilled through the end of November 2019, with a capacity of 169.9 MW. The results exceeded the initial estimated capacity. In addition, CO2 emissions are expected to be reduced by 600,000 tonnes from 2022.
During the construction phase of the plant, 94 staff members received training in drilling, contracting and financing, as well as health and safety management. Around 44% of trained members are women. In addition, 249 staff members of the Geothermal Development Society, including 93 women, received group training. The construction of the power plant benefits about 500,000 Kenyans, including 70,000 in rural areas of the country, as well as businesses and industries. More than 600 jobs have been created.
"The ultimate goal of the project was to help Kenya overcome severe electricity shortages caused by variability of hydropower generation, which forced the country to resort to expensive backup thermal production between 2011 and 2012, and which continued through 2018," according to a Bank project completion report.
In 2011, Kenya embarked on an ambitious path of renewable energy development with the adoption of the Low-Cost Electricity Development Plan for 2011-2031. This plan has been updated annually to increase power generation capacity from 1,227 MW in 2010 to 3,751 MW in 2018. In order to electrify the country and meet growing demand, significant renewable energy generation capacity must be added to Kenya's national grid.
The country’s Medium-Term Plan 2008-2012 and its successors, PMT-II (2013-2018) and PMT-III (2018-2022), all part of the so-called Vision 2030 development plan, aim to increase the country's electricity generation capacity to 5,521 MW by the end of 2022.
The PMT-III also aims to promote the development and use of renewable energy sources to create a reliable, good-quality and cost-effective electricity system to support industrial development. To achieve this ambitious and transformative plan, Kenya has turned to the African Development Bank as one of its preferred financial partners.

If 105 MW of power is being generated in Menengai then Kenyans deserve to know. We cannot be in the dark with regards to such a big project.

Kenya is Africa’s largest producer of geothermal energy. This performance was achieved after the completion of several projects; including the Menengai geothermal power plant in western Kenya. According to media reports, the East African country has increased its production from 168 MWe to 672 MWe in 6 years.
As reported by Think geo energy, a public tender for the construction of Menengai geothermal power plant project was released in September 2013, the contract was awarded to OrPower22 (Ormat), Quantum Power East Africa and Sosian Energy.
Each one of the three companies was expected to set up at least a 35MW modular geothermal power plant under a build-own-operate model to generate a cumulative 105MW.
The PPA with Kenya Power was signed in October 2014, followed by a project implementation and steam supply agreement with GDC. Drilling was done by GDC with H.Young building the steam gathering system under an EPC agreement.
In April 2019, Kenya’s independent power producer (IPP) Sosian Energy, signed a deal worth US $65m with a Chinese company: Kaishan Renewable Energy Development, a subsidiary of Zhejiang Kaishan Compressor, to build Menengai III geothermal power plant in western Kenya.
Under the contract, the Chinese company was tasked to drill geothermal wells and install pipes to transport steam to run the turbines of the geothermal power plant. Zhejiang Kaishan also won $18m contract to operate and maintain the future Menengai III geothermal power plant for a period of 14 years.
Think geo energy also reported that the Construction on the first 35 MW geothermal plant in Menengai kicked off in December 2019.
The Construction of Menengai geothermal power plant has finally been completed. According to pumps Africa, African Development Bank (ADB) which is the main financial partner of the project, allocated a total of 108 million dollars for the project. ADB released a project completion report that was published on October 6th 2020.
According to the report, Menengai geothermal power plant, with its 105 MWe, brings the national production of geothermal energy to 672 MWe, making Kenya the first African producer of this renewable energy source. The report also states that the 105 MW power plant consists of 49 steam drillings.
In a statement released by Quantum Power, Menengai Geothermal Project is the second geothermal independent power project in the country, which will strengthen public-private partnerships and enable the country to harness its abundant geothermal resources to provide reliable, low-cost, environmentally friendly base-load electricity.
The project will enable Kenya to make up its electricity shortfall. In the late 2000s the country experienced severe power shortages due to variability in hydropower generation; and had to rely on expensive back-up thermal generation from 2011 to 2018. But with the commissioning of the Menengai geothermal power plant, 500,000 households, including 70,000 in rural areas of the country, will be connected to the electricity grid.
