1. Introduction: Country Profile

• Nigeria is one of the 54 African countries situated in Sub-Saharan Africa. Nigeria lies in the tropics within latitudes 4.32N and 14N and longitudes 2.72E and 14.64E, with land area of about 924,000 sq km, which is about 3.1% of African land area.

• The population in 2006 was 140 million, which was about 15% of the continent’s population.

• Nigeria is a federal republic, made up of 36 States and the Federal Capital Territory (FCT), which serves as the seat of the Federal Government.

• Government is operated through the presidential system, similar to that in North America.

1. Introduction … Cont’d

• Energy supply into the Nigerian economy is abysmally low for its population and aspiration to be amongst the 20 large economies in the world by 2020.

• Huge amount of useful energy in the form of electricity, beyond the current value of about 20TWh/year from an available capacity of about 4000MW, must be injected to get this national aspiration on tract.

• However, this must be done in a responsible and sustainable manner.

1. Introduction … Cont’d

• One of the risk factors to sustainable development is the adverse effects of climate change reported to be induced by the upset of natural balance of green house gases (GHG) in the atmosphere, particularly carbon dioxide (C02), over periods of about 30 years.

1. Introduction ….. Cont’d

• However, the excess carbon dioxide in the atmosphere responsible for climate change is also reported to be largely contributed by the consumption of fossil fuels mainly in transportation, power generation and process heat activities.

1. Introduction … Cont’d

• This presentation briefly looks at the low carbon opportunities in the Nigerian energy sector, in its quest to meet the energy demand needed to grow prosperity in the nation.

4. LOW CARBON OPPORTUNITIES

a) Hydropower

Nigeria with a hydropower potential of about 15,000MW has about 2000MW only exploited. A large unexploited potential therefore exists that needs to be developed fully. This is an option that needs to be pursued with all urgency and vigour

b) Solar Energy:Solar energy has the greatest potential to contribute enormous amount of low carbon energy in Nigeria through solar PV and solar thermal process. About 15MW of solar PV systems, are dispersedly installed in the country, for street lights, water pumping for drinking and sanitation, lighting and communication etc.

c) Wind Energy

Nigeria’s wind reforms 2-4m/s at 10m height is considered low for wind farm electricity generation using conventional wind generations. However, there may be localized areas with greater wind speeds, where reasonable electricity could be generated there from.

e) Nuclear Energy:

A 1000MWe PWR nuclear power plant is being planned to come on stream by 2020. A Nigerian atomic Energy commission and Nigerian Nuclear Regulatory Authority are in place for the programme.

4. Low Carbon Opportunities…Contd

• f) Natural gas: Natural gas, a fossil hydrocarbon gas, is mainly composed of methane gas – a gas with the least carbon atom per molecule. Over 70% of the grid connected power generation capacity in Nigeria are natural gas driven. There is room for more gas utilization in power generation and process heat generation using efficient power cycles.

g) Energy Demand Management Option: Energy Efficiency & Conservation

▪ Use of energy audit to identify and rectify areas of energy wastage

▪ Labeling of appliances according to efficiency levels

▪ Use of efficient energy appliances like CFLs, LEDs, improved woodstove, efficient refrigerators and air-conditioners, electric motors etc.

▪ Use of combine cycle power plants to improve overall power efficiency (integrated solar combine cycle (ISCC) & (IGCC)

5. CHALLENGES

• Relating higher initial investment• Inadequate legal instrument for low carbon

energy development• Inadequate human and manufacturing capacity

for low carbon energy systems’ development• Inadequate Incentives for the low carbon energy

sub-sector (FIT, fiscal & financial)• Inconsistency in Government policies

6. CONCLUSION

• Nigeria requires huge amount of energy to get its economy in the path of prosperity. The energy supply must, however, be done in a manner that allows for sustainable development.

• Low carbon energy systems from solar, wind, hydro, biomass, nuclear and natural gas as well as the use of efficient power cycles and energy systems would allow for sustainable development in the long term.

• However, appropriate legal instruments are required.
