Ghana has a
long track record of efforts to create a stable energy mix with different
energy sources. The country has gone through a number of phases starting with
diesel generators and stand-alone systems to hydro energy dams and thermal
stations powered by oil or gas.
Nevertheless,
the evolution in energy mix made little to help to overcome regular
fluctuations in the power supply. An electricity crisis, unfortunately, has
already become one of the most pressing issues to be solved by Ghanaian
government as the increasing demand by industrial sector and developing
infrastructure needs sustainable and secured energy sources.
The
Institute of Statistical, Social and Economic Research (ISSER) in 2014
estimated that Ghana would lose between $320 million and $924 million per year
in productivity and economic growth respectively due to the power crisis.
This power
crisis has different manifestations. Firstly, not every Ghanaian citizen has an
access to the electricity. According to a statement made by the then Ministry
of Power, around 80% of population can enjoy benefits of electricity, and in
rural areas, this figures are 60%. Indeed, in comparison with other Sub-Saharan
countries that is sound data, but in order to sustain development it is not
enough.
Ghana’s
annual energy demand is set to grow by 10 to 15% when supply generally does not
meet set targets and lags behind. The expanding industrial sector, rapid
urbanization, the growth of the middle class, and growing incomes, together
with overall population growth (about 2.3 % per annum), have become major drivers
of increasing electricity demand.
Moreover,
power crisis manifests itself in inadequate power supply infrastructure,
over-reliance on thermal and hydropower and gas, high cost of fuel for
electricity generation, transmission and distribution losses.
Currently
Ghana relies on thermal plants, which cover main base load demand. At the same
time hydropower is used as a load-following source of energy. Thermal power has
grown from 330MW in year 2000 to above 2,000MW at present and will continue to
dominate the national energy mix.
Overall
hydro generation provides, approximately between 35% and 45% of the installed
capacity and approximately 36% of energy supply. Further
relying on rainfall to supply water to the dams to generate electricity may not
be quite optimal due to changing climate patterns.
Thermal
power plants fueled by oil and gas also have soft spots. One of the drawbacks
of these stations is their inability to attain and sustain full and secured
generation capacity due to limited and expensive fuel supply.
While Ghana
has committed itself to universal electricity access and become a dynamic
economy, the real challenge that the country needs to resolve is to ensure that
energy supply is reliable and adequate.
In this
case, nuclear energy development can be a perfect solution. Nuclear power is a
cost-effective and reliable base load power source. In countries that opted for
nuclear energy it has ensured uninterrupted power supply for 60-80 years at a
predictable price which does not depend on the volatility of global prices for
energy resources. For instance, if the price of uranium doubles, the final cost
of electricity generated by nuclear power will only increase by roughly 5%,
which cannot be said about conventional energy sources.
At the same
time, nuclear energy is a key component of a clean and sustainable energy
strategy. Today nuclear generation makes it possible to avoid the emission of
over two billion tonnes of CO2 each year.
Nuclear
energy can address the competing needs for greenhouse gas emissions reduction,
economic development and energy security. A wider deployment of nuclear power
will reduce the cost of achieving emissions reductions, and increase the
chances of meeting climate change objectives.
Nuclear is
recognized as a crucial mitigation technology and many more developing
countries are planning to use nuclear generation to meet their emission
reduction and energy supply objectives all over the world.
Today energy
generation by nuclear power has proven to be one of the safest in the world.
After Fukushima accident, modern nuclear plans have all necessary requirements
set by the IAEA. In particular modern energy units have balanced mix of
multi-level active and passive safety and security systems. One of the main
features of modern reactors is its simple design which has a combination of
active and passive safety systems which do not require the nuclear plant’s
staff intervention in case of emergency for several days.
For
instance, innovative Russian reactors have unique in the world passive heat
removal system, hydrogen recombiners and active zone “core catcher”. This
“catcher” is located in concrete vault under reactor vessel and ensures the
melt localization, which excludes possibility of its spillover out of the
reactor vessel at the plant under any circumstances. The evidence over six
decades shows that nuclear power is a safe means of generating electricity. The
risk of accidents in nuclear power plants is low and declining.
Nuclear
power is the only large-scale energy-generating technology which takes full
responsibility for all its wastes. Nevertheless, virtually the amount of
radioactive wastes is very small relative to the waste produced by fossil fuels
like coal and oil. Used nuclear fuel may be treated as a resource since it
contains uranium and some other fissionable transuranium elements that can be
recycled in nuclear reactors to produce energy.
Safe methods
for the final disposal of high-level radioactive waste are technically proven.
Some modern nuclear technologies are capable of reusing nuclear waste making it
possible for nuclear industry to become non-waste industry at all. Russia
successfully implements recycling of materials from once-used nuclear fuels
thus saving the natural uranium resources.
Additionally,
Ghana’s active development of nuclear industry can emerge high-tech clusters
which would integrate different industries, advance in medicine, science and
technology. All that will create well-paid jobs and attract foreign
investments.
A
sustainable energy mix with nuclear power will contribute immensely to the
national economy and business to embark upon the way of dynamic progress,
increasing their competitiveness and attractiveness on a global level. Nuclear
power technology is widely recognized to be the prerequisite of sustainable
energy development and this is in the focus of the International Nuclear Energy
Agency Activity.
Ghana’s
current electricity experiences are detrimental to economic growth and
development. In order to combat the current energy challenge faced by country,
Ghana needs access to affordable and reliable base load nuclear power.
Apart from
securing sustainable, low-cost and clean energy, nuclear industry creates
thousands of jobs in various fields. For instance the implementation of the
Kudankulam NPP construction project in India has led to the creation of more
than 10,000 jobs in the region where the plant operates, not to mention new
jobs in equipment-manufacturing companies.
Globally, an
average nuclear power plant generates nearly $16 million in local tax revenue
per year. This has a direct benefit regarding development of schools,
hospitals, roads and other important infrastructure.
Developing
nuclear energy has other positive implications like foreign investments in technologies
and innovations, improved terms of domestic trade and production.
Stable and
balanced energy mix will allow Ghana to meet set targets of GDP and economy
growth to become a strong emerging African economy and pioneer of new
technologies development. In addition to that, introduction of nuclear power
will definitely lead to increase of the national intellectual potential. It is
the nature of this technology that combines recent achievements in science and
engineering.
Ghana has
already made significant steps forward towards nuclear energy. In 2008, Ghana's
government officially announced plans to introduce nuclear energy. The
Government has enacted its nuclear energy comprehensive law which allows for
the establishment of an independent nuclear regulatory body, the Ghana Nuclear
Regulatory Authority. Establishment of an independent national nuclear
regulator is an essential prerequisite for the establishment of a nuclear power
program.
The IAEA for
its part in ensuring that all nuclear power programs are developed in a
sustainably safe, secured and safeguarded manner has completed, in January
2017, a successful Phase One (1) Integrated Nuclear Infrastructure Review
mission for Ghana, ahead of a government decision planned for 2018 on the introduction
of nuclear power.
In June
2015, Ghana signed a nuclear co-operation agreement with Russia to enable the
development of contractual and legal frameworks for co-operation between the
two countries in the sphere.
It also
enables the promotion of Russian technology in West African markets and the
practical start of joint nuclear projects. This year Russian Rosatom nuclear
corporation and Ghana’s Atomic Energy Commission (GAEC) already held first
meetings of the Joint Coordinating Committee (JCC) as part of implementation of
the Intergovernmental Agreement on the peaceful use of atomic energy as of June
2, 2015.
The meeting
agenda included all key issues related to the preparation for the
implementation of Ghanaian own nuclear power program: infrastructure, staff
training, financing, technical issues related to construction of facilities for
the joint projects and regulation in the nuclear power industry.
All this
proves that Ghana seriously considers the nuclear option as a vital
prerequisite for sustainable and technological development. It also should be
borne in mind that balanced energy mix will allow Ghana to become electricity
export leader in the region and a role model for neighbor countries.
