Nigeria needs a minimum of 60,000.00 Mega watts of
electrical energy for sustenance to be called an industrial nation. By
international standards, each household should be able to lay claim to
3.45KW of energy at any time of the day continuously. To be an
industrialized nation it then presupposes that Nigeria should be able
to generate 90,000.00 MW of energy at any time non-stop. The question
which is then being asked is: why then can we not generate more than
4000 MW of electric power which is considered not enough to power the
Lagos Metropolis of over 10 million inhabitants with skyscrapers and
heavy industries? Is it that we do not have the oil, gas, wind,
water,
ocean current, geo thermal, bio thermal and solar sources of energy to
do it?. Yes we have that in abundance. Is it that we do not have
the
technology to utilize the above natural resource to actually generate
300,000.00 MW at our disposal?. Yes we do have. Do we have the manpower
to manage the energy successfully and profitably? Yes we do. Do we have
the financial resources to do it? By the Grace of God we do have.
Then what is our problem? It is simple: we are not
sincere with each other. Everybody is selfish and what goes around
comes around and it is affecting us in all aspects of our economy and
administration. But the case of energy is a task that must be done
because without us getting a minimum of 30,000.00MW within 5 years, we
should forget Nigeria as a nation because Oil revenue will surely
diminish. The United States, our biggest customer is looking within for
gas and also shall surely reduce its external importation of crude oil.
Alternate energy sourcing within the US is imminent and most of their
automobiles would either be hybrid or full electric cars. It therefore
behoves on us to properly channel our resources now towards providing
energy and maintaining it, without it there can be no economic progress
for the nation.
It is no news that already established industries
are opening new and bigger branches or embarking on outright relocation
out of Nigeria to neighbouring countries due to lack of power. But when
the country is turned into darkness and employment rate gets to 90%,
since less than 10% of our graduates get employment every year, and
those that think they are safe because they have big generators start
being kidnapped, we will all know that this is a national problem and
we all have to fight this endemic problem once and for all. Those of us
who are overseas are not safe either because all it takes is for the
jobless to start kidnapping our families for ransom.
There is no doubt that PHCN cannot handle the power
problem. This is not a problem created by the company but jointly
created by the bureaucracy of government we have been running since we
became a nation in 1960. The issue of PHCN is not a matter of whether
the company lacks the necessary manpower or focus; it is purely a
question of bureaucracy which is a bottle neck to efficient management
of available resources. Until the company is unbundled for efficiency
with empowerment and financial independence there will also be
expenditure down the drain as it happened in the last administration.
It may be painful but I believe that PHCN should only handle the
transmission grid as a government organization for security purposes.
Generation and local distribution (Utility) should be privatized.
The National Network will need a minimum of 1
trillion naira to be able to handle power above 15000MW. Our 132/133KVA
national network must be fortified, maintained, modernized with the
latest technology and also expanded into other areas with restitution
lines to other areas that deserve higher demand like Lagos,
Porthacourt, Abuja, Kano and Aba axes. The Interstate
Transmissions of
33KVA can be jointly owned by local distribution or generation
companies as per convenience and logistics of operations. Since
it is
the local distribution(Utility) companies that give bills to the
consumers, all classification of sources and its elemental costs must
be shown on the bill with legislation backing it up for NERC to sue or
penalize any company that circumvents the law and guidelines to protect
the consumer as it is done in the United States.
In the small town of 100, 000 inhabitants where I
live in California, we generate electricity by Wind, biomass and hydro.
The distribution company for my town and some central valley areas is
PG&E. The company must show in my bill every month where the energy
consumed was generated and the elemental cost for generation,
transmission and local distribution cost. Because the local company has
the right to buy first from the local generation company if it is
cheaper and more reliable than the national transmission line and can
change anytime the local generation company cannot meet demand or when
it is idle for maintenance. This competitive attitude guarantees
stability for electricity to consumers and improves the economy.
Whilst it will be advisable for PHCN to continue to
maintain and manage all the present hydro power stations for the next 2
to 5 years until there is stability above 10000MW national requirement,
all other sources of gas power like Egbin and the new gas powered
companies must be privatized unless the FGN is ready to secure a new
and bigger restitution fortified pipeline from Brass to Lagos.
I will advise that the sale of these establishments
should not be handled by the BPE but by the Stock Exchange through its
normal shares handling process. This process enables some staff within
PHCN who are interested in Gas generation posted to these
establishments and private ones to join them to manage profitably
whilst individuals and companies that are interested in them can buy
the Federal Government shares profitably instead of allowing an under
the table system. If this system had been adhered to in the sale of
NITEL, that organization would not have encountered the problems it has
today. The system will allow foreign companies to invest without fear
of insecurity of their investment and instability of government and its
insincerity.
As part of localization of generation through hydro
process there are more than 100 water dams located in various
communities in the federation that can generate between 500KW to 100MW
of electricity. With latest technology step up transformers it is
expected that the generation can be improved by 400%. The generation is
expected to first benefit the locality by first option purchase from
local utility distribution companies and the second option directly
selling it to the National Transmission Company at prices regulated by
NERC. The River Basin Authorities of the Federal Government and States
Water Resources Dams have a lot to do in this area. There is no reason
for the River Basin Authorities going into PPP agreement with any
company; it will be a diversion of primary duties despite their good
intentions wanting to be like other nations’ Departments of Water
Resources.
National interest is very important; making sure
that all these idle Dams are fully utilized for generating power,
providing raw water to the communities and irrigation for localized
farming and agriculture. If private entrepreneurs are allowed to use
the Penstocks of these dams, it is possible to generate 2400MW of
electricity to the locality within 15 months and also improve
generation to 5000MW utilizing the existing idle dams and new
technology step up transformers.
About 75% of the Nigeria land mass is on what is
called grid 4 of solar array map. It is therefore possible and viable
to farm solar via Solar Thermal and Solar PV. Though Solar PV
(Photovoltaic) requires large land mass, this is available in the
Northern Part of the country and Borno state shares part of the grid 5
of abundant Solar energy (as in Sahara Dessert) which has enough
land
mass to generate multiples of 500 MW that is enough to power
140,000
homes per farm. About 70% of the land mass in Borno State has 10 hours
of direct sunlight which has excellent photons for direct energy.
Due to urgent call for renewable energy in the
United States, many Solar companies are presently involved in such
ventures on very large scale. A vivid example is SunPower and OptiSolar
companies having a joint venture with PG&E California to build the
largest solar PV plant in the world, 800 megawatts in total, powering
239,000 homes in California. In order to reduce load on the National
Grid and assist local utility distribution companies to meet demand,
large Corporations like CBN can get incentive to utilize roof tops in
15 of her branches to generate at least 14kw energy that will be more
than enough to power lightings and computers. It is not just about
solar panels or specialized batteries but much more of planning -
expensive initially but cost effective for long term investment. The
Solar Thermal technology type can be also very useful to our
Telecommunication companies for their base stations, hospitals and
government secretariats.
State Governments in conjunction with private
companies can create solar thermal farms. Kano State is a good example.
A 280 megawatt solar thermal plant will produce electricity for 60000
homes as it is being done near Phoenix Arizona, USA. The project alone
will create construction employment for more than 3000 people at a go
which will reduce unemployment of youths in that area.
Enough wind blows in the Northern part of the
country at speed more than 40m/sec which shows that wind farming is
very profitable in the area. Abuja metropolis (FCDA) can take advantage
of undeveloped areas as prototype areas for wind farming for sale to
interested entrepreneurs. Ocean current wind along Victoria Island in
Lagos is a very vivid source of multiples of 500 KW turbines for 10 MW
to 100MW power generation. Wind farming is a clean alternate
energy
source. Gas thermal generation is very costly and also involves annual
routine maintenance, companies should be encouraged to establish Ocean
wind and under current wind turbines in multiples of 500kw to 2MW in
Rivers and Bayelsa Ocean fronts.
Coal mines in Taraba and Enugu States are areas
that Nigeria must invest in and sell to private companies. If properly
channeled, it is possible to sell the coal in Taraba for good
processed coking coal.
There are enormous wastes in our cities to generate
Electricity. There is no reason why large cities like Lagos, Ibadan,
PH, Abuja, Kaduna, Kano, Benin, Onitsha, Aba, and Abeokuta cannot take
a lead in this process. It takes 285 metric tones of wet soiled city
waste in Nigeria to generate 10MW of electricity even when it is wet
and sandy.
Though our wastes are not classified like many city
wastes in developed countries, the new technology of preheating the
waste with calendaring vibrator or rotator drums gets the waste
ready
for thermal furnace chambers that will generate 10MW in turnkeys at
multi locations. It is a fact that Lagos Metropolis produces
waste
close to 10000 metric tones everyday and its Ikorodu area dump can
accommodate more than 1 million metric tones. That alone for a start
can be a source of 200MW in 10MW multiples.
The Cement industries in Ewekoro, Sagamu and
Ubajana are vivid examples of companies that have excess energy up to
80 MW each that can be encouraged to sell to the local utility
companies which can industrialize or boast the economy of areas of
location.
If Ajaokuta was in operation, the gas flared from
the Open Heart furnace was expected to generate 180MW to the national
grid and also to the locality. ASCON is a sorry case of a beautiful
well planned project that has gone down the drain. I have not seen a
developed country without a full Steel mill. We have only one in the
country. Aladja which is on ‘direct reduced system’ was established to
meet the ever-increasing construction needs of Nigeria whilst ASCON was
set up to create many downstream industries like Automobile parts,
Railway construction parts, plastic industries heavy designs and parts,
specialized designs customized for Nigeria, Naphthalene to mine Bitumen
for road construction, Oil and Gas parts, Slag for road construction,
and so many others including power generation. What a waste!
