Kenya Electricity Generating Company PLC has earned Sh2.6 b in revenues from commercial innovation initiatives over the last nine years.
This emerged as the company held its 9th Global Innovation Seminar virtually for two days ending today.

The company also made a savings to the tune of Sh1.3 b drawn from process improvement and implementation of continuous improvement ideas.

Energy CS Charles Keter urged the company to continue with its tradition of generating ideas adding that their candle will be used to light the way for other players.
He also challenged the energy sector to continue harnessing natural resources efficiently to not only avail clean power but also assure Kenyans of its reliability.
“I look forward to proposals aimed at improving the generation process, reducing overall electricity cost along the supply chain or adding efficiency solutions such as storage of energy as this is what our country is in dire need of,” The CS said at the start of the seminar.
Energy, he added, is critical in delivery of Kenya’s development blueprints - Vision 2030 and the Big Four Agenda and ideas generated from the G2G seminar may be the catalyst required to transform the country’s economy for future generations.
He however stressed the need for development of solutions geared towards improving energy generation process, reducing overall cost of electricity, and adding efficiency solutions such as storage.
KenGen Managing Director and CEO, Rebecca Miano said the organization is making good progress to bring on board its first solar project of 42MW which may in future be coupled with its existing hydro generation to efficiently utilize both resources.
“This is in line with our pursuit for green, sustainable energy, aimed at positively exploiting the available resources while reducing the country’s thermal power bill,” she added.

She reiterated that currently the company is on track to commission the Olkaria I Unit 6 geothermal power plant later this year, adding that at 83.3MW, it will be the single largest geothermal generating unit in Africa.
“This power plant being an extension of Olkaria I Units 4 and 5 means that when complete the power plant will be a 233MW geothermal giant. This addition will push our installed capacity to 1.9GW, double the 956MW KenGen had when we embarked on our ‘Good to Great’ journey in 2008 and only 100MW shy of the two Gigawatts mark,” she said.

SHARE PAGE:


24 Jun 2021
KETRACO has energized the 400/220/132kV Olkaria - Lessos Kisumu transmission project (OLK project) from Olkaria II through Lessos substation to Kibos substation. Currently transmitting at 220kV, the project will facilitate reliable and stable power to the Lake Basin Economic Block Counties that include: Bungoma, Busia, Homa Bay, Kakamega, Kisii, Kisumu, Migori, Nyamira, Siaya, Trans Nzoia, Kericho, Bomet, Nandi and Vihiga. The project will also strengthen the National Grid and facilitate reliable and stable power supply to Kisumu Seaport.
The transmission line will facilitate power trade between Kenya, Uganda, and Rwanda. Lessos substation will be connected to Tororo via the Lessos – Tororo transmission project (Kenya – Uganda interconnector).
Lessos substation upgrade will provide a strong link for power export and import to and from countries of the Eastern Africa Power Pool (EAPP) through our 127km 400kV Lessos – Tororo transmission line (Kenya - Uganda interconnector).
KETRACO Board Chairman Hon. (Capt.) Joe Mutambu, MBS said the Kshs 18 billion transmission project, co-funded by Japan International Cooperation Agency (JICA) and the Government of Kenya (GoK) will strengthen the link between the Olkaria Complex where there exists massive geothermal energy potential and the Counties within the Lake region of the grid where demand is fast growing.
‘’OLK will compliment GoK’s commitment to increase electricity generation from the current 2708MW as of June 2020 to estimated 5,000MW by the year 2030 and provide cost effective renewable power,’’ noted Capt. Mutambu.
The project has 848 towers and over 5,580km in conductors strung. It has 1,700 hectares of wayleave traversing Nakuru, Uasin Gishu, Nandi, and Kisumu counties.
The construction of the Olkaria – Lessos Kisumu project was undertaken in three Lots; Lot 1 involved the construction of the 230km, 400kV double circuit transmission line from Olkaria II substation to Lessos substation.
Lot 2 involved the construction of the approximately 70km, 220kV double circuit transmission line from Lessos substation to Kibos substation as well as construction of 9km 132kV double circuit transmission line from Kibos substation to Mamboleo substation.
Lot 3 involved the construction of the new 220/132/33kV Kibos substation and extension of the existing 400/220kV Lessos and 220kV Olkaria II substations.
Construction works for lot 1 was undertaken by KPTL-KINDE JV of India & Japan, NARI-CCCE JV, both of China took charge of lot 2 while SIEYUAN - NIEIE both of China dealt with lot 3. JV of NIPPON KOEI Co. Ltd, Japan and GIBB Africa Ltd, Kenya were the project consultants.
“Energy is an enabler of economic, social, and political transformation towards a globally competitive and prosperous Kenya. Energy is critical to the realization of Kenya’s Vision 2030 and Big 4 Agenda which seeks to transform Kenya into a newly industrializing middle-income Country providing a high quality of life to its entire citizenry,’’ said Capt. Mutambu.
“This transmission project will be ideal as an enabler during the forthcoming Africities Conference scheduled for November this year and will indeed elevate Kisumu City to international Standards,” he added.
Fibre optic cable strung along the transmission line will promote broadband connectivity in areas it traverses as some areas are currently served by narrowband microwave connectivity, thus enabling faster connectivity to voice, data, and video services like e-health, e-learning, security surveillance, and other government digital services.
KETRACO Managing Director, FCPA Fernandes Barasa, OGW noted that with the injection of reliable power, there will be an upsurge of Special Economic Zones (SEZ) within the block and create the much-needed opportunities for jobs for the unemployed youths.
‘’ Industrial Parks and Small & Medium Enterprises (SMEs) will attract both local and foreign investments and enhance technology development by industrial parks and innovation and promotion of rural and regional industrialization, ‘’ added FCPA Barasa.
Kisumu County is currently supplied by Sondu Miriu and Sang’oro hydropower plants through the Sondu – Kisumu transmission line and Tororo – Musaga – Lessos – Muhoroni transmission line as well as the diesel-powered Muhuroni – Mamboleo line.

Is Tanzania ready to tap geothermal for power generation?​

Making a case for a more complete look at energy options and their output, engineer Chagaka Kalimbia points to geothermal energy and its promising role in Tanzania.

In a personal commentary published in The Citizen Newspaper in Tanzania, energy specialist and project management professional Chagaka Kalimbia currently working for Tanzania Geothermal Development Company, makes a passionate case for geothermal for his country and beyond.
Despite originating from the engineering lexicon, Megawatt, an electrical power unit of measurements similar to kilometers in length has enjoyed mainstream recognition. The effortlessly grasping of Megawatts amongst the public is certainly due to the constant reverberations of the unit amongst the parliamentarians and decision-makers who seek to demonstrate strides and gaps in the electricity supply industry. Within the power-hungry nations, Megawatt has remarkably stapled the controversial status on various occasions. Sometimes in 2010, the Zambian Government Official was furiously quoted in favour of Megawatts than lengthy fruitless political promises in the power sector, he asserted- We need Megawatts, not Megawords. Fascinatingly, the kilowatt-hour, a crucial index for the actual electrical energy produced from the installed Megawatts never receives the equivalent attention. The under-appreciation of kilowatt-hours as a pivotal criterion can be detrimental when making sound decisions in the development of the vibrant power sector. From the technical standpoints, different generational sources inherently yield different kilowatt-hours from a Megawatt except when running at full blast. A power plant with enormous nameplate Megawatts while producing fewer kilowatt-hours is costly to run, infeasible, and unsustainable.
According to Tanzania’s Power System Master Plan of 2020, the total grid-installed power capacity stood at 1,565.72 Megawatts with the portfolio heavily skewed to natural gas and hydropower. It can furthermore be deduced from the Plan that more than 60% of grid-based Megawatts are sourced from fossil fuels, let alone the significant contribution of far-flung regions not connected to the grid which banks on the same. The over-reliance on fossil fuel Megawatts not only frustrates the global efforts of attaining universal access to environmentally benign energy services but also equipped with the risk of resource depletion, susceptibility to international price shocks, and environmental pollution, particularly emission of Carbon dioxide. It is also worth mentioning, despite hydropower being a cleaner generation source than fossil fuels, the ongoing threat of global climate change perpetuates the odds of worsening droughts and prolonged dry spells hence posing a stern sustainability question to the country’s most ancient generational source.
The disruptive but yet pragmatic solution to all of the shortcomings hinge on the optimal integration of Megawatts from all the existing sustainable energy generation technologies and, geothermal energy is one of the most imperative. The technology uses heat that originates from the Earth’s core in form of steam to spin the turbine blades to generate electricity. As the heat being continuously generated at the Earth’s core, the technology can effectively supply all of humanity’s energy needs if the technical and commercial barriers particularly those associated with drilling deeper geothermal wells are lessened. The U.S. Department of Energy GeoVision report estimated the total worldwide geothermal thermal Megawatts being more than twice the amount needed to supply total global primary energy consumption in 2015.
The East African Rift that doubly traverses Tanzania, provides unprecedented access to geothermal energy – this is elucidated by the observable alignment of several thermal springs along the rift, some with temperatures up to 80 degree Celsius. Kenya is the only country in the region and the continent with commercial geothermal electric power production with a capacity of more than 800 Megawatts – the first Megawatts installed in the mid-80s. To this day, geothermal is proven to be mature, a low-operating-cost, renewable, reliable, affordable and clean electricity supply. A Megawatt from a geothermal plant does not only ensures tremendous kilowatt-hours but also guarantees uniquely reliable power around the clock-not subjected to oil price shocks and negative impacts of climate changes.
The national geothermal company [of Tanzania] reported completion of geoscientific surveys and siting of best targets for exploratory wells in its flagship prospects of Ngozi, Songwe, and Kiejo-Mbaka. The ongoing drilling project at the latter prospect has revealed, at the very shallow depths, a large geothermal reservoir seated below the prospect. These optimistic findings and indications amongst many others cement the confidence and readiness of the next Megawatts in the national grid injected not from fossil fuels or hydropower but the geothermal steam. The ‘whys’ and ‘hows’ to meet these goals are indisputably established and certainly, the ‘when’ is just around the corner.

Geothermal Development Company to expand muscle in Africa​

by Christine MuchiraJuly 5, 2021
SHARE

The Geothermal Development Company (GDC) is committed to building capacity of geothermal practitioners in Africa as part of its South-to-South solutions strategy.
The Company announced this strategy when it received 20 fellows, staff of Djibouti Geothermal Energy Development Authority (ODDEG).
The fellows are in Kenya training at GDC’s iconic Menengai Geothermal Project.
They are now undergoing training in nine key specialized areas in geothermal resource development. Some of the areas include drilling operations, environmental sciences, geophysics, geology, and geochemistry.
The 29 days training has been funded by the Bundesanstalt fur Geowissenschaften and Rohstoffe (BGR) of Germany.
The GDC Managing Director and CEO Eng. Jared Othieno has further reaffirmed his company’s interest in supporting the growth of geothermal energy in Africa.
“Technical know-how is critical to the success of geothermal development in Africa. At GDC, we’re always ready to share our unique expertise with our friends in the region. Our facilities, sites and instructors will be availed to serve our continent,” the GDC CEO said.
And at the Menengai Geothermal Project, the Djiboutians see the path to their country’s success in geothermal exploits.
One of the start attractions at Menengai is the drilling rig simulator. We caught up with Mr. Adsieh Aden Kanil keenly following instructions on how to drill.
The 3D screen and the baritone voice of the pre-recorded instructor, carefully and calmly guiding what to do. Mr. Kanil is clearly excited. His other colleagues sit at the back of the 5 by 5 meter console following the instructions and taking notes. Each of them waiting for their turn at the console.
“It’s exciting. It’s like real. There is a lot to be discovered but this is a right beginning,” Mr. Kanil enthuses. He hopes when he goes back to his country, he will be able to drill without any hitches. He hankers for the day Djibouti will power its economy using geothermal energy.
“We appreciate that GDC has been committed to training us,” he says. “Your instructors are friendly, patient and very knowledgeable. We hope one day we can be like them,” he says.
GDC has emerged as an unparalleled Geothermal Centre of Excellence in Africa. The Company has heavily invested in training infrastructure such as rig simulators, laboratories, and drilling rigs.
The company is said to be having some of the best geothermal scientists in Africa as well and is now leveraging on this expertise and unique infrastructure to support other African countries that seek to develop their own geothermal resources.
This is not the first time GDC has trained experts from Djibouti. In 2018, GDC successfully trained 12 ODDEG staff. The training was tailor-made to focus on strengthening capacity of ODDEG staff to improve their practical experience through on-the-job-training at GDC’s Menengai geothermal field.
The Company has established a robust training programme that it says will uplift the geothermal technical-how of most African countries.
Dr Robert Ogutu, the Ag. Principal, Geothermal Centre of Excellence at GDC reckons that training in Kenya for geothermal technology is far much cost-effective. Iceland, Japan, the United States and New Zealand are other renowned training destinations in the world .Though world class come with a bit of high costs. GDC, therefore, is Africa’s hope in geothermal development.
So far, GDC has trained over 800 experts drawn from different parts of Africa including Comoros Islands, Tanzania, Uganda, Ethiopia, and Malawi.
The Company is planning to build a training Centre on its land in Kabarak that is aimed at cementing GDC’s place as the ultimate hub of geothermal development in Africa.
