States hope cross-border electricity connections will boost supplies, largely from hydro, as well as energy access
YAOUNDE, Cameroon, Feb 17 (Thomson Reuters Foundation) – Central African governments are pushing forward with a cross-border response to meet the region’s swelling need for new energy supplies, which aims to fight poverty and climate change at the same time.
Large parts of Central Africa have big potential to generate hydro-electric power, which could help pull more than 700 million people out of poverty, officials say. Insufficient energy supplies have been a major hurdle on the region’s path towards economic growth.
According to Cameroon’s energy and water minister, Atangana Kouna, low access to energy has hampered efforts to meet the Millennium Development Goals, contributing to acute poverty and high child malnutrition rates.
“The Central African region is facing a huge development setback that can be addressed through investments in energy supply and energy infrastructure,” the minister told a November meeting in Yaounde that endorsed an implementation plan for a regional energy strategy.
The plan, which runs through to 2030, has since been approved by energy ministers from the Economic Community of Central African States.
The Central African Power Pool, which organised the Yaounde gathering, will coordinate the inter-state electricity connection project, based on a $4.6 million study funded by the African Development Bank (AfDB).
Authorities say the project will provide a regional response to Central Africa’s energy and development challenges, curb greenhouse gas emissions, and give a boost to the emerging economies of Cameroon, Gabon, Chad, Central African Republic, Republic of Congo, Democratic Republic of Congo (DRC) and Equatorial Guinea.
“(It) will help countries… have expanding access to hydro-electricity while participating in a global transition to clean, low-carbon energy systems,” said Pierre Marie Ngnike, an environmental expert in Cameroon’s ministry of water and energy.
The plan includes a 700 km interconnection line between Ngaoundéré and Maroua in Cameroon and N’Djamena in Chad, and a second section around 250 km long linking the two countries.
The scheme will also put in place rural electrification along the corridors of the new transmission lines, connecting local communities to a power supply.
According to Cameroon’s ministry of water and energy, electricity access rates are only 18 percent in Cameroon and as low as 3 percent in Chad.
Yet both countries are rich in energy resources, which remain unharnessed. Cameroon has economically viable hydropower potential of over 12,000 MW, of which only around 6 percent has been tapped.
Meanwhile, the Chadian government has begun to develop oil production, eyeing medium-term opportunities to generate electricity from petroleum gas. It hopes to export power to Cameroon, especially during dry periods.
Another grid interconnection project between Cameroon, Gabon and Equatorial Guinea aims to promote energy exchanges, making power cheaper for users. This will entail the construction of a high-tension overhead power line, and is being funded by the AfDB to the tune of $150 million.
In addition, work is underway on a new 3,800 km transmission line that will run from DRC to South Africa through Angola and Namibia, due to be completed by 2018. The purpose is to feed electricity to be generated by the Inga III and Grand Inga hydropower schemes in western DRC into the Southern Africa Power Pool.
This programme includes an option to extend the line to Gabon, Equatorial Guinea, Cameroon and Chad.
Cameroon’s strategic development vision through to 2035 has a goal of advancing the country to middle-income status by reducing poverty and industrialising its economy.
This will be tough to achieve without adequate energy infrastructure. The country’s current low level of electrification “is a handicap to the production of goods and services”, the vision states. In rural areas, only 3.5 percent of people have access to electricity.
The government’s objective is to ramp up the national electrification rate to over 48 percent, and the rural electrification rate to over 20 percent by 2020.
DROUGHT AND DISPLACEMENT
Like other countries in the region, Cameroon has recently launched new hydro and thermal gas power projects.
The Central Africa interconnection scheme is also expected to create around 3,000 direct and 5,000 indirect jobs.
However, there is disagreement over the efficacy of relying on hydropower.
“Hydropower is a renewable source of energy, relying on water that is continuously replenished through the natural cycle,” said Martin Mesumbe Akame, an official in the ministry of water and energy. “It is near-zero emissions, and can be dispatched quickly to meet peak electricity demand.”
But critics point to production falls during dry spells, saying Cameroon’s high dependence on hydroelectricity increases its vulnerability to droughts, which could worsen with climate change.
Samuel Nguiffo, coordinator of the Centre for the Environment and Development, a Cameroon-based NGO, said Central Africa needed energy for development, but the social and environmental costs of constructing hydropower dams were often too high.
“People have to be displaced, communities along the project area have to sacrifice their land and livelihood for little or no benefits, and the natural environment is destroyed,” he said.
He pointed to the Memve’ele and Lom Pangar hydroelectric dams in the South and East regions of Cameroon, for which large tracts of forestland have been cleared.
Inequitable distribution of benefits can sometimes spark conflicts that call into question the overall value of such projects in meeting energy needs, Nguiffo added.
