Kenya: Govt Steps Up Geothermal Power
3 October 2012
Kenya has inaugurated Africa's biggest geothermal power project in a
bid to meet its growing need for electricity and lower its consumption
of nonrenewable energy.
The 280 megawatt (MW) Olkaria Geothermal Project was commissioned by
Kenya's president, Mwai Kibaki, in July. It is being built at a cost
of 82.5 billion Kenyan shillings ($980 million) and is due for
completion in June 2014.
Experts say that it should be an important source of "green" energy in
a country that has seen its hydropower production hit by worsening
The project "will be an effective source for power for Kenya in the
sense that it will help the country manage its competitiveness in the
region and in global markets, especially for agro-based industries
that for many years have suffered from costly, inefficient and
unreliable power," said Chris Ackello Ogutu, an agricultural economist
at the University of Nairobi.
If farmers get access to cheaper and more reliable geothermal energy
to help process their crops, "then their vulnerability to climate
change-related stresses (will) diminish," he said.
Drilling of steam wells for the new facility has already taken place,
and these will generate power even before the permanent geothermal
plant has been put in place, officials say.
The new plant in particular will help Kenya reduce its heavy reliance
on hydroelectricity, which is an increasingly uncertain energy source
as rainfall becomes more erratic, a situation that experts believe is
related to climate change.
Two geothermal units, each with an output capacity of 140 MW of
electricity, will make up the new plant at the Olkaria Complex, some
80 km (50 miles) northwest of Nairobi, Kenya's capital.
Two other geothermal plants constructed in the 1980s and 1990s are
already in operation at the complex, which was Africa's first
geothermal project. The new plant will be Africa's largest and will
almost triple Olkaria's capacity to 430 MW.
The project is being funded by the Government of Kenya, the Kenya
Electricity Generating Company (KenGen), the World Bank, European
Investment Bank, and the development agencies of France, Germany and
The geothermal project is expected to boost current Kenya's power
output of 1,588 MW by 18 percent, according to Eddy Njoroge, managing
director of the Kenya Electricity Generating Company. The company is
Kenya's leading power generator, producing nearly 80 percent of the
80 PERCENT GREEN POWER
Njoroge adds that the project will increase the proportion of KenGen's
electricity derived from green sources to more than 80 percent. (The
remainder comes from nonrenewable sources such as diesel generators.)
Geothermal power will contribute more than one third of this green
The new project is one of several aimed at increasing the capacity of
the national grid by as much as 140 percent over five years to help
meet growth in demand. By 2030, the government plans to raise power
output to 15,000 MW, from a current 1,500 MW.
"We have plans that in five years' time we will be in a position to
contribute more than 50 percent of our total electricity capacity
(from geothermal power) so that the country can avoid expensive modes
of generation," Njoroge said.
Experts believe the Olkaria Complex could produce additional
geothermal power beyond that now being tapped.
According to field optimization studies conducted by Mannvit
Consortium of Iceland, the complex is capable of producing an
additional 560 MW of power. Current estimates place Kenya's total
geothermal potential at 7,000 MW.
Nashon Adero, a policy analyst with the Kenya Institute for Public
Policy Research and Analysis (KIPPRA), said the project is one of many
green energy initiatives being promoted as part of the government's
Least Cost Power Development Plan, which looks ahead as far as 2031.
"Geothermal is seen as the preferred power generation for Kenya
because its operation costs are less than other modes of power
generation, and in the long run (it) can help the country achieve a
reduction in unit cost of power by 50 percent," he said.
Geothermal power is less expensive than hydropower, he said, and will
also significantly help reduce the country's greenhouse gas emissions
from fossil fuel power generation.
Emissions from geothermal power generation are just 10 percent of
those from oil-based power generation, Adero said.
He said Kenya's Great Rift Valley gives the country a competitive
advantages in that it offers suitable geological conditions for
harvesting heat from the earth's crust to generate electricity.
"Even though sources of renewable energy in such countries as Ghana
and the Democratic Republic of Congo are significant, these are mainly
hydropower based," he said.
But Kenya lags behind other African countries in terms of per capita
power availability, figures show. Kenya's power availability, for
instance, is less than half that of Ghana, according to the Kenya
Economic Report of 2010, compiled by KIPRA.
And improving power generation alone will not improve the country's
economic prospects, Ogutu warned.
"Policy issues remain problematic and labour costs have tended to make
Kenyan products a lot more expensive than they ought to be," he said.
One of the challenges facing the project has been the relocation of
people to pave way for construction. About 270 homeowners are affected
by the plans, and they will be resettled on a 690-hectare (1,700
acres) parcel of land on which 164 houses are being constructed.
Churches, a school and teachers' accommodation, a library, and a
cattle dip and watering trough will also be built by KenGen.
"We hope to have put the necessary infrastructure in place as well as
completed the resettlement of families by next year in February," said
