WASHINGTON, D.C. --
Developing countries that are interested in geothermal energy may see
transformational results by approaching World Bank and other
institutions, as Djibouti did. In an interview, the World Bank Djibouti
geothermal project team talks about the project investment, lessons from
Kenya’s experience, and preparations that are being made for the
private sector to take up the next steps.
In October, the World Bank Group and the Government of Djibouti
signed geothermal project financing agreements for the Lake Assal
project in Djibouti. World Bank will provide a US$6 million highly
concessional credit to support assessment of the site’s commercial
potential through its International Development Association arm.
With exploration as far back as the 1970s, and facilities now
operating in Kenya and Ethiopia, geothermal power development in the hot
reservoir areas of East African countries is supported by World Bank as
well as U.S. programs under the Obama administration’s Power Africa
initiative, like the Geothermal Energy Association’s East Africa
Geothermal Partnership with the U.S. government. The World Bank Djibouti
geothermal project team answered a few questions. (Many thanks to Ilhem
Salamon, Charles Cormier, and the rest of the World Bank Djibouti
geothermal project team.)

LB: Why did World Bank choose the Djibouti geothermal project as its first exploration financing venture in almost 20 years?
WB: The Djibouti Geothermal Power Generation Project
came to fruition primarily as a result of Djibouti’s strong confidence
in its geothermal potential. Since the 1970s, the Government of Djibouti
has shown an enduring commitment to develop its geothermal fields and
two exploratory drilling programs conducted in the Lake Assal have shown
the existence of significant, albeit highly saline, geothermal
resources. Following failed attempts to develop the resource through the
private sector, Djibouti reached out in early 2010 to the World Bank to
seek support for the exploration phase of the development of geothermal
power generation.
In response to Djibouti’s request, a thorough technical review of
previous exploratory drilling programs was carried out with financing
from the Energy Sector Management Assistance Program (ESMAP), a
multi-donor technical assistance trust fund administered by the World
Bank. The findings proved that, based on available geo-scientific
results, the Fiale Caldera in the Assal Rift is a very promising
candidate for geothermal development. The Djibouti geothermal
exploration program was subsequently developed by the Government of
Djibouti, the World Bank and six other co-financiers.
(The project has 7 co-financiers: the World Bank (US$6 million), the
Global Environment Facility (US$6.04 million), the OPEC Fund for
International Development (US$7 million), the African Development Bank
(US$5 million), the Sustainable Energy Fund for Africa (EUR 1.8
million), the French Development Agency (EUR 2.5 million) and the Energy
Sector Management Assistance Program (US$1.1 million). Finally, the
GoDj will make an in kind contribution of US$0.5 million.)
The project will focus on assessing whether large scale geothermal
power generation is possible and is the first phase of a two-step
process to develop local geothermal generation capacity. If the resource
is confirmed for large scale power generation, the intent is to follow
up with a tender to attract private sector know-how to develop, operate
and maintain a power plant, provided investment risks can be identified
and mitigated.
The use of concessional financing for the exploration phase reduces
the overall cost of geothermal power development in Djibouti by US $52
million, compared to a project that would be fully funded by the private
sector. This translates in savings amounting to around 4 US cents/kWh.
Geothermal electricity cost is expected to be around 9 US cents/kWh,
significantly lower than current tariffs in Djibouti. In terms of
overall impact of the project on Djibouti’s finances, the replacement of
thermal capacity by geothermal power generation is expected to save
around US $57 million per year.
Overall, geothermal power has the potential to help reduce Djibouti’s
electricity production costs by 70 percent, boost access to electricity
for the population and alleviate the country’s energy dependency. Given
its potentially transformational impact, the project is a clear
priority for the government and the people.
LB: Many countries across the region are interested in
developing their first geothermal projects and are struggling to find
the right balance of rules, legislation, and business incentives to
attract investors. What made World Bank choose this one?
WB: As outlined above, concessional finance is used
to enable the implementation of the exploration phase of geothermal
development in Djibouti and subsequently encourage private sector
involvement. If the exploration phase is successful, the intent is that
the geothermal resource will be tendered to the private sector, which
has the know-how and capacity to develop geothermal resources.
In order for the power plant development phase to be successful, the
public private partnership (PPP) infrastructure and institutional and
legislative framework in Djibouti needs to be markedly strengthened. The
World Bank with the Public-Private Infrastructure Advisory Facility is
currently providing technical assistance to Djibouti to strengthen its
PPP framework. Other international donors, such as USAID and the
Japanese International Cooperation Agency, have expressed their interest
in providing support on this.
LB: World Bank has supported geothermal in Africa before,
back as far as 1978 in Kenya. What were some lessons that the Bank is
implementing into its Djibouti experience?
WB: The World Bank Group has been supporting Kenya’s
geothermal development since the 1970s. Geothermal power now accounts
for over 12 percent of the installed capacity in Kenya’s national grid,
including a geothermal IPP, and the vulnerability of the country’s power
supply to hydrological risks and fuel price volatility has been
reduced. It has significantly contributed to stabilize supply of
electricity, which has helped improve people’s livelihoods and fostered
income-generating activities. The video link below shows some of the
impacts geothermal power has had in Kenya:
Some of the key lessons learned from the Kenya experience include:
(i) government commitment and support to geothermal development is key;
(ii) approach to geothermal development should be tailored depending on
site and stages of development; (iii) having a dedicated unit
accountable for geothermal activities is important; and (iv) there must
be conscious effort to accumulate technical capabilities on the ground
through learning-by-doing and extensive capacity development activities.
These lessons have been incorporated into the Djibouti Project
through (i) the Government’s investment and acceptance of concessional
financing for exploratory drilling, (ii) the development of a
site-specific drilling program resulting in certified well test results
which will be incorporated into any future tendering documents of (iii)
the establishment of a clear chain of responsibility and authority over
the project that runs through the project management unit (PMU) to the
Director General of the electricity utility Electricite De Djibouti
(EDD), and (iv) capacity building through direct interface and training
of the EDD and Centre for Studies and Research of Djibouti (CERD) staff
with international geothermal teams which are taking the project lead.
LB: Africa’s economy is growing faster than any other
continent, something that then-Kenyan ambassador Elkhana Odembo
mentioned at a Geothermal Energy Association event earlier this year.
How does WB react to this draw and related aspects like involving the
local community and ensuring environmental steps?
WB: To accommodate and foster rapid growth in the
continent, investment in key infrastructure including reliable power
supply will be crucial. Geothermal power presents a unique opportunity
by enabling clean and sizable baseload power supply in a
cost-competitive manner. In many countries, it also enables both
mitigation and adaptation to climate change by allowing low carbon
growth while reducing vulnerability of the electricity grid to
hydrological risks. Governments in the region are trying to harness
geothermal resources in an environmentally and socially sustainable
manner. In Kenya, for example, consultations with local communities are
undertaken and the entities concerned are supporting livelihood
improvement activities benefiting them. In the future, geothermal
resources could also support social development through direct use of
residual heat. The World Bank is also encouraging the entities to
conduct cumulative environmental impact assessments whereby
environmental impacts are assessed holistically in targeted geothermal
fields.
LB: At geothermal industry events in the U.S. we have seen
growing interest and excitement in regard to opportunities in East
Africa. How is geothermal energy being received in Djibouti?
WB: Geothermal exploration started in the 1970s in
Djibouti and several attempts were made to develop the country’s
potential. The development of geothermal energy is today a national
priority of the Government of Djibouti, and Djiboutians are eager to see
it finally happen, as it would help replace expensive thermal power
generation and reduce electricity cost, thus enabling a greater access
to electricity.
In other parts of East Africa, and spearheaded by Kenya, geothermal
development has been progressing steadily since the 1970s. East African
countries, such as Ethiopia, Kenya, Tanzania, Uganda, have been
experiencing steady economic growth over the last several years. This
economic growth increased the electricity demand in general, and the
countries have to look for new energy resources to meet this growing
demand. Countries with limited energy resources had to depend on
expensive thermal power plants running on imported fuels. To ensure
sustainable growth and competitiveness, countries decided to invest in
developing indigenous renewable energy sources. Initially, the countries
started with developing their hydro power resources and then continued
to tap into their wind power resources. Given the relatively higher risk
perception and upstream capital requirement to develop geothermal
energy, progress in this area was initially limited. However, the high
level of reliability, the low level of meteorological risk, and the
baseload power supply characteristics of geothermal energy have
increased East African countries’ interest to invest in this energy
resource over the past years.
LB: World Bank’s funding will be for the assessment phase.
What are the biggest factors and risks considered at the current stage?
WB: During the exploration phase, the highest risks
are geological in nature. In the case of Djibouti’s geothermal program,
geological mapping identified the rift anomaly and confirmed potential
geothermal resources through exploratory drilling starting in the 1970s.
More recently, additional professionally executed geological surface
studies were performed by Reykjavik Energy Incorporated (REI) in 2010.
These studies have led to the identification of the Fiale Caldera area
drilling targets. Given the vertical fracturing of the caldera,
directional drilling will be used to reduce risk by increasing the
probability of locating the fluids that move through these permeable
fractures. Finally, the drilling program design includes the engagement
of a qualified international Geothermal Consultant, whose
responsibilities will include development of the final well design, the
targeting of four full size production wells, and the management of the
technical field drilling operations.
Djibouti’s 36-month exploratory drilling program is currently in the
initial stages of tendering the program positions that will be held by
international companies with proven technical and management expertise
in the geothermal arena.
LB: Djibouti’s present energy needs are estimated at 50 MW;
is there an expected timeline on when energy needs will be reached, and
is there potential for exporting extra power?
WB: The World Bank has recently completed a least
cost generation study for Djibouti with funding provided by the
Public-Private Infrastructure Advisory Facility (PPIAF). This study
provided recommendations to the Government concerning the most effective
means by which Djibouti can continue to maintain and as necessary,
renew, its existing power plants to meet projected electric demand
through the year 2022. The study recommendations have taken into account
the coordination of bringing a 50-MW geothermal plant on the line by
year 2022 to support Djibouti’s electricity demand. In the event that
the exploratory drilling does not result in geothermal power generation
potential, the least cost generation plan will require revision to
schedule an alternate generation technology to meet Djibouti’s year 2022
demand. Given the anticipated coordination between Djibouti’s current
generation base and the introduction of 50 MW of geothermal power,
geothermal power export is not currently being considered.
LB: Apart from Lake Assal, Djibouti has six other prospect
areas for geothermal potential (Nord-Ghoubbet area, Manda Inakir area,
Abhe bad area, Obock site, Roueli area, Garabayis site); does World Bank
have interest in any of these sites?
WB: At this stage, World Bank engagement focuses on
the potential of geothermal energy in Djibouti and paving the way for
private sector interventions. If the exploration phase is a success, the
private sector will be enticed to invest in geothermal in Djibouti.
Approximately twelve geothermal provinces have been identified in
Djibouti based on the locations of surface hydrothermal manifestations.
In preparing the Djibouti Power Generation Project, priority was given
to the prospects of Lake Assal, Nord-Goubhet and Lake Abhé. The Lake
Assal site was ultimately selected for the project due to the fact that,
since the 1970s, geologic research and testing and two exploratory
drilling programs in the area have shown the existence of a significant
geothermal resource.
To our knowledge, there has been no exploratory drilling or
definitive confirmation of a geothermal resource suitable for power
generation in Nord-Goubhet and Lake Abhé. The geologic features of these
areas and the surface studies performed to date show that these sites
are promising prospects for further geothermal study in the form of
exploratory drilling, potentially to be carried out by the private
sector.
LB: World Bank has announced their Global Geothermal
Development Plan. Can you tell us about upcoming plans or prospects for
this, especially in the East Africa area?
WB: The Global Geothermal Development Plan (GGDP) is
a call to donors, multilateral development banks, government and
developers to work together around an investment plan to scale up
geothermal power in the developing world.
The GGDP focuses on exploratory drilling, which is the most difficult
to finance given the high geological risks. The goal of the GGDP is to
develop a pipeline of commercially-viable projects that are ready for
funding. The GGDP is led by ESMAP, the energy trust fund of the World
Bank and developed in collaboration with multiple stakeholders. To reach
its goal, the GGDP:
- Deploys technical assistance to identify and structure investments that by definition include a high risk and require significant co- and parallel financing to share the risk among a range of funding entities.
- Helps mobilize concessional capital to finance the projects identified
- Facilitates knowledge dissemination to share lessons learnt about geothermal exploratory drilling project design and implementation.
Through the GGDP, a new window of US$115 million has been established
by the Clean Technology Fund for support to the private sector for
geothermal exploratory drilling. These funds will be deployed to
eligible middle income countries with high geothermal potential, such as
Chile, Indonesia, Mexico, and Turkey. In addition, ESMAP has provided
some support to poorer countries in scoping out options for support to
governments or private sector to finance geothermal resource validation
projects with a focus on Kenya, Ethiopia, and possibly Tanzania and
Rwanda.
