This is the future – Minigrids not nuclear, bringing power to 620m Africans
Businesses which ignore the impact of technology raise the risk
of bankruptcy. Ditto Governments. Today’s well intentioned but poorly
researched decision often creates tomorrow’s millstone. Nowhere in South
Africa is this more evident that the Zuma Administration’s obsession for a nuclear power fleet
whose cost threatens to land future generations with an unaffordable
mortgage. The future belongs to those who apply human ingenuity, to the
nimble, the gazelles. Not to command and control economics like those
applied by the long since collapsed USSR. The story below provides an
example of how smaller is better is succeeding where grand plans have
failed – by delivering electricity to 620 million Africans left out the
loop. – Alec Hogg
(Bloomberg) — Power grids that work at a fraction of
the scale of a traditional utility have gained support from banks and
developers as a way to bring power to the 620 million people across
Africa that lack access to electricity.
From Kenya to Equatorial Guinea and Tanzania,
companies including Italy’s biggest utility Enel SpA and General
Electric Co. of the U.S. are building minigrids that distribute power to
villages instead of whole nations.
A plunge in the cost of renewables has opened a new
source of power for minigrids. While these smaller electricity networks
deliver only a trickle of electricity, they’re demonstrating a way to
bring energy to the poorest areas without lifting
pollution. Institutions including the African Development Bank are
supporting them as a way to balance goals on economic growth and global
warming, promising the industry will expand beyond a few pilot
projects.
“If you go back 130 years in Europe, electrification
started with a minigrid,” Francesco Starace, chief executive officer of
Enel, said in an interview. “There was a rich man, his house, his
factory and a small power plant. Eventually his workers got hooked up,
and then transmission lines were laid. Slowly we got the system we have
today. We don’t see any reason why Africa shouldn’t do the same.”

Africa’s needs for power are immense. The continent
has more than 620 million people who lack access to electricity, and
consumption per capital is less than what’s needed to keep a 50- watt
lightbulb going continuously, according to data from the International
Energy Agency.
Minigrids are increasingly viable because rapidly
falling costs for wind and solar mean developers have many more options
than diesel generators for powering the systems. Minigrids also are
cheaper and quicker to build than a traditional utility with a coal
plant at the middle and high-voltage power lines radiating out to
customers.
Enel is developing a minigrid in western Kenya for 100
villages. It will run on solar panels and wind turbines, with battery
storage and diesel generators as back-up for nights and when there’s no
breeze. Construction is due to begin in three months.
General Electric of the U.S. along with Princeton
Power Systems Inc. and MAECI Solar are working on a sun-powered minigrid
on the island of Annobon in Equatorial Guinea. The unit will have a
capacity of 5 megawatts and will be operational by the end of 2016. Its
$56 million cost was financed the government of the oil-rich nation.
A Nairobi-based company called Powerhive is building a
solar system in Kenya. It will have a capacity of 1 megawatt to 2
megawatts and is financed by investors including the Arizona panel maker
First Solar Inc. and an unidentified European utility.

In Tanzania, a partnership dubbed Jumeme Rural Power
Supply Ltd. is building a 5-megawatt minigrid for 16 villages in the
nation’s northwestern region. Austrian renewables developer
TerraProjects e.U., Germany’s Inensus GmbH and St. Augustine University
of Tanzania are involved in the project. The European Commission and the
Sustainable Energy Fund for Africa along with private investors are
underwriting the cost of 17 million euros ($18.3 million).
“A single-house solar panel system is great, but it
just powers a lightbulb or two,” said Joao Duarte Cunha, coordinator of
the Sustainable Energy Fund for Africa. “A minigrid can power businesses
and stimulate the local economy.”
The African Development Bank is supporting that
project, part of an ambition to triple annual financing for projects
aimed at combating global warming to $5 billion by 2020. It’s backing
more renewables as costs plunge.
“The costs were the biggest challenge to building
renewables in Africa, but this is no longer the case,” said Alex
Rugamba, director of the African Development Bank’s department of
energy, environment and climate change, by phone. “There is a huge
untapped potential in our continent. We have to mobilize private
financing, create enabling environments on the policy front.”
The bank expects the project in Tanzania to create 500
more businesses in addition to the 2,600 in the area that will be
supplied by the minigrid. The project will eventually expand to connect
500,000 people, said Leo Schiefermueller, managing director of
TerraProjects.
“We believe up to 120 million, about 20 percent of the
people in non-electrified regions in Africa, could be connected to
minigrids,” Schiefermueller said by phone.
Developers are working on ways to extend microgrids to
new markets. Powerhive is evaluating work in Nigeria, South Africa,
India and the Philippines. It also recently submitted a bid to build a
minigrid in Madagascar.
“I see renewables as the future for Africa,”
said Angeli Hoekstra, Africa power and utilities leader at the
consulting firm PwC. “An especially big opportunity is using them for
the development of off-grid systems.”
