Wind, solar and hydro energy have all been highlighted as sources of energy that help meet Africa’s growing power needs. Ghana’s Dela Wosornu is using garbage.
Decomposing organic material, known as biomass, releases gas that can be used to create energy in the form of biofuels. In Ghana, a country with a vast amount of degradable material, it is a viable option for alternative energy.
In Ghana, energy is costly and scarce; this hinders economic growth.
Biomass, such as wood and charcoal, is Ghana’s main energy source, supplying around 60% of the total energy used in the country. Biomass resources cover about 20.8 million hectares of land mass in Ghana. Most of this land is made up of crops and plants that can be converted into solid and liquid biofuels. Wosornu, a renewable energy entrepreneur, is taking advantage of this by transferring landfill gas to energy.
He is involved in the Oti Sanitary Landfill Gas-to-Energy Project, which eliminates the emission of harmful greenhouse gases as well as the spread of disease from the waste. The project reduces the reliance on producing power from fossil fuels by producing energy from the waste that would have otherwise been buried in the landfill.
The solution is quite innovative.
When organic material, such as food waste, is buried in the landfill, it is deprived of oxygen. In this condition, the organic material will decompose and turn into methane gas. The methane will slowly be released into the atmosphere, causing global warming. The project at the Oti landfill doesn’t let this happen. They cover the landfill with soil and drill holes into it. Pipes are then inserted and the gas is sucked out into a generator which makes heat and electricity.
“It’s really a matter of just bringing pipes to where the gas has collected and pumping it out through a vacuum process and then directing that gas to a generator,” says Wosornu.
According to Wosornu, the project is the first of its kind in Ghana. As cities grow and produce more waste, the environmental impact from open dumps becomes increasingly intolerable. The conversion of dumps to engineered landfills like the Oti project is essential.
“Our solution can be applied at any landfill that has received at least 400 tons a day of municipal solid waste and is in reasonably good shape. As there are many landfills in Africa and around the world that are not capturing gas, the future for landfill gas to energy projects is bright,” says Wosornu.
Landfill gas to energy projects have underperformed relative to projected gas and power output. Bearing this in mind, the projected output of the Oti project has been discounted by 70% so that its actual output will meet or exceed the projected output. The Renewable Energy Act in Ghana ensures that there are set prices for each class of renewable energy. It also offers an opportunity to redirect future investments into green energy.
The challenge for Wosornu, is finding reliable buyers for the project’s output. The high cost of doing business in Africa also makes the development costs of these projects higher than the rest of the world.
“There is no doubt that, if properly exploited, renewable energy resources in Africa can make a significant contribution to the continent’s energy supply. In particular, the potential of biofuels on the continent is huge. Within the context of the current financial crisis, stakeholders including policy makers, international partners and the UN should lead the debate on and collectively seek strategies for scaling up renewable energy use so as to increase access to energy and enhance energy security among the many potential benefits of these technologies,” says Kandeh Yumkella, Director-General of the United Nations Industrial Development Organization (UNIDO).
Wosornu is playing his part.

Full Steam Ahead

From Junk To Power

When Luke Callcott-Stevens, Gavin James and Doug Jenman first talked to FORBES AFRICA in 2012, they struggled to imagine what their $274-million 100MW wind farm in Dorper, South Africa, would look like. A big project with big risk.
“We built a wind farm, we installed it. All those are effectively at the cost of capital. Now it’s done… Every three days a wind turbine is being installed in South Africa,” says Jenman.
Forty wind turbines and two and a half years later, this trio from Rainmaker Energy can not only take pictures of Dorper, a tiny town in the Eastern Cape province, they are now imagining that they can cover the rooftops of London with solar panels.
“The cities of tomorrow will produce their own electricity. We won’t need power stations,” says James.
With this bold idea, the trio set up shop at 81 Rivington Street, an old electrical showroom, in London’s tech hub Shoreditch, and also, by coincidence, labeled with a fitting coat of arms “More Light More Power”.
“A lot of our growth is happening in the solar field, and it’s out of South Africa. We’ve set up a separate company in the UK, Solar Stone Energy; effectively we are trying to create a utility scale solar project on rooftops. So we are aggregating a bunch of rooftops to build a big solar power plant,” says Callcott-Stevens.
It gets even more pie in the sky – especially when we are talking about a city where the sun doesn’t shine often – the trio want to give solar panels for free.
“We cover the costs of the installation and on-going monitoring and maintenance. There is absolutely zero cost to you. You then get to enjoy the immediate benefit of reduced energy costs because the electricity, which is produced on your property’s roof is yours to use, for free. By generating electricity on your roof, we receive a Feed-in-Tariff (FiT) through a government-backed subsidy program. This is how we fund the solar installations and make a return on investment. It’s a win-win for everyone.”
They feel it could find favor with London’s 8.3 million people.
“If you look at what’s happening in the States and in Europe, in solar and wind energy, people are putting solar on their roofs and creating their own power. That is not a total solution, but it cuts back on the need to create new power plants, it changes the game. The utility business is now losing out on its most profitable market. That demand is now gone,” says Callcott-Stevens.
“Solar has gotten cheaper. Next storage is going to get cheaper. That’s not to say you won’t have coal or nuclear power stations. It just changes the game. It changes the dynamics,” says James.
Back home in sunny South Africa, where 39 renewable energy projects contribute 1,800MW to the grid, the trio’s 100MW wind farm in Dorper has been humming for more than a year. Although James says it will take another 16 years to see a profit, it couldn’t have come at a better time. Eskom, South Africa’s power supplier, regularly cuts the power – a legacy of under investment and delays in coal-fired power stations, such as Medupi and Kusile. The work of renewable energy dreamers has been a saving grace.
“Eskom’s troubles are our blessings in the whole [renewable] industry. It’s been good. The government has put its weight behind the program,” says James.
“They are seeing results and they are happy with it, so the whole fear that renewables is erratic and unreliable actually is false. Apparently the first projects have reduced power cuts by half. We would have double the power cuts if it wasn’t for the renewable projects,” says Jenman.
The competition for new projects is stiff. Last year, Eskom announced that 77 bids were received for Round 4 of the program, for a total of 5,804MW. Of these, 13 were accepted as preferred bidders, for a total of 1,121MW installed capacity at a cost of R23 billion ($1.8 billion).
“By the fourth round, the tariff prices have halved. The game’s changed. The perception of risk is gone. In Round 1 there was no market in South Africa; people were taking a lot of risk without knowing if there was going to be a market. They needed higher returns. Where we are now, the return expectation is lower, as it should be, as the market grows and matures,” says Callcott-Stevens.
“Without getting those high returns in the beginning we wouldn’t be in a place where we are established,” says Callcott-Stevens.
Hope of more business in Africa is in the wind. The trio has a further 330MW of wind and 290MW of solar photovoltaic (PV) projects under development in South Africa.
“Africa is the future – solar is all over. There is potential everywhere. Sub-Saharan Africa is obviously closer to home so it’s easier to look at. The [solar rooftop] model works really well in a deregulated market. In South Africa, we are still highly regulated,” says James.
“The rest of Africa is highly regulated. Either badly regulated, or highly regulated. We don’t want to just get on a plane and go find a site. We like to have an angle before we choose a market. There needs to be a reason before we can just go into that market. We can’t just go into a country and just say we are building a solar plant. We need to have relationships, we need to know people, we need to understand the market first,” says Callcott-Stevens.
From the dream of a small windy farm in the middle of nowhere, in Africa, to the reality of free solar panels on the rooftops of London where the sun hardly shines. What next?

The Cities Of  Tomorrow  Won’t Need Power Stations

She is the fresh face of renewable energy in Africa. By a twist of fate, this young lawyer, who grew up with her grandmother by candlelight, is now spearheading Africa’s dash for energy.  Sometimes it hurts.
“It feels like I haven’t slept for four years, I have been so busy working on deals. But it was the deal of a lifetime.”
So says Linda Olagunju on her deals to put two wind farms and two solar photovoltaic (PV) farms onto the barren landscape of De Aar in the Northern Cape. Two deals she patched together that will contribute 254MW to South Africa’s energy grid.
“The wind projects reached financial close and are currently under construction. It’s a partnership between China Longyuan, Mulilo and DLO Energy Resources in De Aar. It’s been almost one year of signing documents. The legal fees on these sorts of transactions can go up to R20 million ($1.57 million) if you are lucky.”
It’s the fruit of the Renewable Energy Independent Power Producers Procurement (REIPPP) program. In short, Eskom, the country’s power generator, attracted bids for private business to apply for tenders. Under it, investors generate electricity for sale at a tendered rate. This brings the total committed private sector investment in the REIPPP, since 2011, to $13.25 billion (R168 billion). It is fierce competition.
“There about 85 solid IPP [independent power producers] developers in South Africa. In Round One to Four, there was 5,200MW on offer, the next rounds are 6,300MW. It’s a bloodbath. You are competing with international companies that are coming in dirt cheap,” says Olagunju.
This may be a drop in the ocean but it’s a very important one. Renewables have been a saving grace. According to Olagunju, 39 of these projects are up and running, supplying 2,050MW to the grid.
“It’s the first successful program since democracy. It’s not that there haven’t been any independent power producer programs on the continent. It’s just that this one is the largest one of its scale and being backed by government.”
Olagunju’s childhood was far from electricity. She grew up in Matatiele, a village in the Eastern Cape 782 kilometers from the boardrooms of Sandown where she now works and lives with her Nigerian-born husband.
<img loading="lazy" decoding="async" class="alignleft size-medium wp-image-3955" src="/wp-content/uploads/2017/04/IMG_5178-300x200.jpg" alt="" width="300" height="200" />
“It was rural, like candle rural… [My grandmother’s village] only got electricity in 2005,” says Olagunju.
This was in time for the power cuts of 2008, when Eskom admitted that it had run out of capacity to supply electricity. At this time, Olagunju had left home to follow in the footsteps of her father and study law. At the University of Cape Town she studied laws governing fossil fuels rather than green energy.
“I’ve always known I was going to go into resources. I just didn’t know if it was going to be mining or oil and gas. The biggest thing for me is why Africa, which is so well endowed in resources, remains the poorest continent. I always hated injustice, growing up in apartheid South Africa,” she says.
Olagunju struggled to find her niche and ended up as a lawyer for Mulilo, a startup renewable energy company in 2008.
“Mulilo needed a lawyer, but couldn’t afford any. So I said I would do the services in return for shares. I still had to pay for them. At the time, the company [owed] R11 million ($870,000) and the company is now valued at R5 billion ($394 million)… in three years,” she says.
This sparked her idea of entrepreneurship.
“I always felt the way to change things is through entrepreneurship. Through law I had the opportunity to see how government makes these decisions on large scale projects… I said ‘hang on a minute, we have a lot of wind in South Africa and we have a lot sun in South Africa, so why haven’t we put renewables on our grid?’ I started doing research,” she says.
The business of renewables can take years to see a profit.
“There is a lot of risk, anything can go wrong. You are in a contract for 20 years, governments can change and I know there are laws to take care of that risk. The wind may not blow for as long as you thought it would. Your sun may not shine as brightly as you thought it would. They are long-term projects.”
“You identify the land. You go into lease agreements. Do an environment impact assessment (EIA) process that can take three years if you are lucky. You then bid your process with a construction period. If everything goes right, [a farm] will be up in 20 months.”
“Then you start seeing a trickle dividend. A trickle dividend at connection in the first seven years is very minimal. It’s nothing to write home about. It’s not even enough to pay your operational expenses.”
Then, there are the hiccups.
“We have existing infrastructure. And then we have the [REIPPP]. The grid infrastructure hasn’t been expanded to accommodate the increasing demand on that particular infrastructure. It’s not Eskom’s fault necessarily. It’s a matter of planning.”
“One of the points we raised before we began these projects is getting the grid contacted properly before you have a program. But it’s always difficult how you spend on infrastructure not knowing where those programs are going to be awarded.”
“Eskom said that they have developed a map where they now know where the hotspots are for energy projects and where now they are doing their best to upgrade in those regions in anticipation of the other [REIPPPs] being built.”
Olagunju believes gas, coal and nuclear could all go the same way.
“You can go and leverage an asset and try and participate. The key thing about these deals is to learn from them. Once you do one, you have built a portfolio. You can go and knock on a door in Nigeria, rather than say you have an idea,” she says.
If you are Olagunju, at the tender age of 31, you could also argue it’s good to have a foot in the door.

A Bloodbath In The Wind

From the boardwalks of Cape Town to the streetlights of Kigali, billions are being made out of renewable energy. It brings business and government together; it could end the days of smoke-belching coal-fired plants. It could answer Africa’s most burning question – power.
In 2011, many experts scoffed at the thought of Africa running on towering wind turbines and miles of solar panels. It was too expensive; it was inefficient and couldn’t stay charged. But, armed with new technology, a pack of young entrepreneurs dug deep to harness the wind and the sun of Africa, to power future generations.
In this continent, South Africa’s Renewable Energy Independent Power Producers Programme (REIPPP) has moved the fastest. In a few short years, South African entrepreneurs have invested $13.25 billion to sell electricity back to Eskom, the country’s hard pressed power generator.
It is fierce competition. According to South Africa’s President Jacob Zuma, 1,800 megawatts (MW) are on the grid and in the next two and half years, 92 projects will generate up to 6,327MW. Further investment into hydro, gas and nuclear power are also on the cards, says Zuma.
The faces driving this investment are fresh. Thirty-one-year-old Linda Olagunju who grew up in an African village by candlelight is now calling the shots in boardrooms. Homegrown entrepreneurs Luke Callcott-Stevens, Gavin James and Doug Jenman threw in their safe jobs for the cutting edge of renewable energy generation. These are a few of the young and restless generation of investors who are taking risks to charge Africa.
It’s a story that breezes through the wind turbines in South Africa to the landfills in Ghana to the underground heat of Kenya.
Some old heads, like nuclear physicist Kelvin Kemm, say that nuclear may yet have a bigger say. He believes three quarters of African countries can become nuclear within the next six years.
It all adds up to an exhilarating story of youth, vision, risk and reward. This month, FORBES AFRICA dedicates our cover story to it.
