At first glance, all is well. Zambia’s immense water bodies are propelling major hydropower plants to meet the nation’s electricity needs in a clean and renewable way. For many years, the country's electrical energy has been generated thanks to water flows from the mighty Zambezi, Kafue, Luangwa, and Chambishi Rivers.
However, the southern African country
is now reconsidering its long-time dependence on hydropower, as chronic
droughts cut production at its massive hydro dams. These droughts - caused by
climate change - have in recent years lowered water levels, severely curtailing
power production. Zambia has as a result seen electricity shortages estimated at around one-third of its total installed hydroelectric
capacity. In 2019, water levels in the Kariba dam - one of the country’s key
manmade dams - plunged to their lowest yet, falling to 10% of usable storage
since 1996.
“This is probably the worst drought
that has hit Zambia since independence in 1964,” Energy Minister Matthew Nkhuwa
recently told parliament.
Chronic electricity
shortages have affected everyone, from individuals to small businesses and huge
corporations.
In addition to unpredictable weather
patterns, a lack of investment in hydro projects has also caused complications.
Even if rain does fall, power supply simply cannot keep up with demand from the
mining, manufacturing, and agriculture sectors.
Zambia’s over-dependence on
hydropower is unsustainable. Energy experts have argued that as droughts lead
to prolonged blackouts, the country ought to be developing other renewable fuel
sources, such as solar and wind energy.
The Zambezi River.
In an effort to diversify its energy
sources, Zambia is entering agreements with corporations looking to invest in
its energy sector. Recently, the country signed an agreement with the IFC to
develop two large-scale solar projects. Only a few weeks ago, Zambia’s
state-owned electricity provider signed a contract with Power China to develop three
solar power plants to feed into its national grid.
Less attention has been paid to wind
energy, but several promising projects are underway. Construction of a 200MW
wind power project in Katete, Eastern Province is expected to start in 2021.
This is the first phase of the larger Unika 1 wind project and will be
financed by private investors.
These impending improvements are good
news for Zambia’s citizens. Chronic electricity shortages have affected
everyone, from individuals to small businesses and huge corporations.
“These projects are badly needed and
long overdue. Look! For me to make it in this sector, I need electricity to
refrigerate my milk products and the rolling power blackouts have wrecked
Zambia’s already fragile economy,” says Pamela Kabwe, a dairy farmer based in
the Chisamba area.
The hope is that
solar energy will contribute not just to a climate-resilient Zambia, but to a
low-carbon continent.
“My business is down due to lack of
electricity,” says Christine Chembe, the operator of a hair salon in the capital city of Lusaka. “The government should prepare adequately to invest in
other renewable energies instead of always depending on hydropower from the
Kariba dam, year in and year out.”
Local markets, shops, and chain stores
are flooded with various solar appliances – from water pumps and radio sets to
phone chargers and lights – as people try to take the problem of blackouts into
their own hands. For David Chibuye, an entrepreneur at Kamwala market in
Lusaka, business is booming. Ever since the power blackouts started, he tells
me, he has been selling more solar-powered equipment. “I never used to have
clients like these days. Nowadays, the demand for solar-related products has gone
up here and, given more capital, I will make more money.”
But this is just the beginning.
Zambia has an average of 2,000-3,000 hours of sunshine per year, waiting to be
turned into energy. The International Renewable Energy Agency estimates that renewable energy capacity in Africa
could reach 310GW by 2030, putting the continent at the forefront of renewable
energy generation globally. When its larger solar energy projects are finished,
both Zambia's natural environment and its citizens will benefit hugely.
Solar power looks set to be the
answer.
As it stands, only 4% of
Zambia’s rural population has access to electricity. Mable Katongo, a pupil at
a rural school in the Kaoma district of Western Zambia, talks to me about the
issues she has studying late at night without electricity. “With examinations
around the corner, it hasn’t been easy to study using kerosene lamps. They
produce toxic fumes that are a danger to one’s health. But what can I do?”
Solar and wind power plants will
decentralize power; they can be connected to micro-grids and supply currently
underserved communities, like Mable’s. The solar power systems in action
already are a testament to just how big an impact this will have on these
communities.
Dennis Kandala of Salanga in Zambia’s
Mumbwa district cannot believe how much his life has improved. After years of
unreliable electricity, his village invested in solar lighting equipment,
solar-powered boreholes and other equally efficient agricultural equipment.
“Solar energy is indeed the way to
go. Look! It has improved my life after enduring years of living without
electricity at my farm,” says Dennis with a huge smile.
Zambia’s Rural Electrification Authority is working
towards providing electricity infrastructure to all rural
areas in Zambia. Quality of life will greatly improve with increased production
of and access to electricity. So far, the Authority has built over 400
standalone systems. Its first Solar Mini-Grid, completed in 2013, provides
electricity for nearly 500 households, a school, a health center, and a harbor.
Many more are on their way.
The hope is that solar energy will
contribute not just to a climate-resilient Zambia, but to a low-carbon
continent. The possibilities for infrastructure, agriculture, and the management
of natural resources are very promising indeed.
“I never thought this would happen
during my lifetime, and that I could have electricity in my house,” says
Dennis, “I assumed perhaps this was going to happen during my
great-grandchildren’s time.”
