Expanding LPG access in Ghana: do innovation prizes have a role?

15 May

It’s the end of April and Accra is hot and humid, the roads clogged with traffic. I’m here with a GVEP colleague for a few days of meetings with officials at the Ministry of Energy about the prizes we’re designing around increasing access to LPG for cooking. The government wants to expand access from the current 20% of households using gas, to 50%. This is an initiative of the President.

The country is in the midst of a protracted power crisis with frequent blackouts affecting industry and domestic customers. Solving the electricity supply problem is clearly on everyone’s minds at the Ministry, and the top priority. One cause of the current power outages appears to be a shortage of LPG for thermal generating plants.

Cooking with LPG in Ghana

Despite these challenges there is high level engagement with the issue of LPG for cooking and considerable interest in how the innovation prizes might help achieve the government target. New policies, which aim to create an environment favourable to private sector investment in the LPG sector, are currently under discussion. Ghana has large gas reserves which are slowly coming on stream. If fuel supply can be secured, distribution can be expanded. The government is being supported by experts from the LPG industry in designing the new policies, but there is a lot of work still to.

The literature on innovation prizes says that design is complex and takes time. That is certainly true of what we are experiencing in Ghana. The government officials and other stakeholders we are working with are all very positive and engaged. But the concept of innovation prizes is new to them, and trying to use prizes as part of a policy implementation is a learning curve for all of us.

Innovation prizes work best when they are part of a wider programme of activity, and in Ghana our prizes need to fully align with the new LPG policies to be effective. Potentially we could contribute to some big impacts, but finalising detailed design is contingent on some of the details of the proposed changes and the timescales over which these will take effect. None of this yet agreed, and therefore not public, which means we cannot talk to some stakeholders. We have to wait for the policies to be approved and for the government staff to conduct stakeholder briefings, expected to happen over the summer, before we can test our prize ideas on some of the people we expect to be our solvers.

We will work through this, and the details of how the innovation prizes will contribute become clearer with each step, but it’s a lengthy process involving much discussion with a range of parties. We’re focusing on three specific areas where we believe an innovation prize can deliver a solution to a problem linked with implementing the new policies. Because the policy changes are still under discussion and have not yet been agreed by the government in Ghana we cannot at this stage disclose details of what exactly we’re planning to do. We have to respect the confidentiality of the conversations currently in progress. What we can say is that one prize will probably aim to incentivise the private sector to develop new distribution models, and another will engage with the public.

If we’ve learned anything in the past year it is that prize design is indeed complex and requires a considerable investment of time to get the focus right. Aligning with wider processes of change is complex, and a political process not just a technical one. Ultimately we believe that, by working closely with the various stakeholders, the impact will be greater.

We’re fortunate in having a funder – DfID – which is understanding of this complexity and supportive of the process.

Kisumu entrepreneurs receive equipment to boost production

15 May

Entrepreneurs in Kisumu town in Western Kenya, have received equipment from GVEP International to scale up production of locally manufactured efficient cookstoves in the country.

Seven entrepreneurs who included two women groups have benefited from machines worth 1.6 million Kenya shillings ($ 17,000) that are expected to help them improve their productivity as well as income from their work.

The equipment handed over to the groups on Monday, 4 May, 2015 in Kisumu, comprised six welding machines, five paint spraying machines, six angle grinders, four bar cutters and 22 tin snips.

“We have given out these equipment to help the entrepreneurs produce quality cooking stoves. The Smart Jikos have been found to be efficient and effective compared to the other conventional and improved cookstoves in the market”, said the GVEP’s Western Region Business Technology Mentor Kevin Okoth.

GVEP was awarded a $375,000 grant in June 2013 from the Global Alliance for Clean Cookstoves’ Spark Fund to improve the performance and quality of locally manufactured efficient biomass cookstoves in Kenya. The Fund is part of the Global Alliance for Clean Cookstoves’ strategy to strengthen supply and enhance demand in the cookstove and fuels sector through innovation and tailored entrepreneurial capacity development.

GVEP has been working closely with local manufacturers and end users, under the Spark Fund, to develop two stove designs (one using wood and one using charcoal) that can offer improvements in performance over current models being made. These designs are currently manufactured and sold by local entrepreneurs who closely work with GVEP.

New hybrid minigrid project to power rural villages in Tanzania

10 Nov

In mid October, I travelled to Mwanza, Tanzania to help coordinate a project that will establish 16 solar-hybrid minigrids in the surrounding region of Lake Victoria.

Mwanza is the coordination base from where the work for establishing the 16 minigrids in the surrounding rural areas will happen. Typically, only 2-5% of Tanzanians in these areas have access to energy. Bwisya, where the first minigrid will be built, is a village on Ukara Island, located 97km away from Mwanza. Bwysia requires two ferry rides (over the course of a day) to get to.

Fishing on Ukara Island is the main economic activity, while cash crops (including cassava and sweet potatoes) are smaller, alternative livelihood sources. The value of the fishing activities is limited in part by lack of refrigeration of the daily catch, which reduces the price that can be paid for the fish. This would be just one of many ways that electricity could improve the livelihoods of those living in Bwisya.

JUMEME is the joint venture that will set up this minigrid. It was founded by partners working out of five countries, including technical consulting and engineering firms INENSUS, TerraProjects, as well as Saint Augustine University of Tanzania. All 16 minigrids that JUMEME will build will serve 82,000 beneficiaries.

This overall mini-grid “project” is really split into two parts. The first one—the “demonstration” or pilot project—is funded by the Energy and Environment Partnership–Southern and East Africa (EEP). The purpose of this project is to set up the Bwisya minigrid.

The second project, which will be simultaneously implemented, is partly funded by the EU (African-Caribbean-Pacific – European Union Energy Facility II Grant). This project is designed to expand from the Bwisya (EEP) project, where 15 additional minigrids would be established in the surrounding region. Because this “scale-up” project also requires private capital, the EEP project would serve as a demonstration that can be used to help source investors and commercial debt.

The GVEP team will organize the EEP-project implementation, while providing ancillary support for the scale-up project. We met for two days with all partners in a conference room on the verdant campus of Saint Augustine University to finalize action items and to allocate specific roles and tasks among the partners. It’s an exciting chapter for JUMEME, as construction in Bwisya is set to launch soon.

The effects of the minigrid establishment will be substantial. For example, in Bwisya, at the very least, electricity would attract economic activities from other areas to the center and stimulate enterprise and entrepreneurial activity. It could revive the village water pump to decrease water-born diseases while facilitating better and cleaner drinking water (currently residents pay for water that could be used to pay for the pump). Other benefits include anything from home lighting (to study, and to reduce smoke from kerosene) to other productive uses—and refrigerating the fish haul—as well as the opportunity to enjoy leisure activities such as watching television.

Solar transforms Tanzanian village

2 Aug

The village of Sakwe is a 3 hour drive east of Mwanza in northern Tanzania. There are around 800 households scattered about. The main street is lined by small stores selling general groceries and other essentials. Sakwe is 4 km from the nearest grid connection. There is small likelihood of the grid extending here and anyway the connection fee is expensive (around $300.) People make a living growing cotton and maize, and raising livestock.

Four years ago the village had no mobile network coverage and few people owned a phone. Everyone used kerosene to light their homes. Today the villagers estimate there are as many as 3000 handsets in the village, network coverage is good, and almost every home has at least one solar lantern. ‘Kerosene is hardly sold here,’ one villager told us.  Solar is providing electricity for essential needs – one of these being phone charging.

GVEP is working with six entrepreneurs in the village who provide phone charging services, and we are about to start work with five more. Antonia Giluli was using a car battery to provide phone charging when GVEP met her last year. She was charging 6-7 phones a day and every few days the battery had to be taken into the regional town of Bariadi for charging. With GVEP’s help Antonia was able to secure a loan from Postal Bank of Tanzania and bought a 50W solar panel and other equipment. Now she charges between 25-50 phones per day. Her record books showed that on one day in June she charged 90 phones. At 200/- (12 US cents) per phone she is making $4-5 a day. Antonia used part of her loan to stock her shop with bicycle spare parts which are much in demand.

Even with 11 phone charging service providers in the village the demand will not be fully satisfied, but competition does mean that the cost of charging a phone has fallen from 300/- to 200/-. Few homes have solar panels and the ability to charge phones at home, but most do have small solar powered task lights thanks to the local promotional activities of Sunny Money. Using schools as a  distribution platform, Sunny Money has brought quality d.light products to the community – the S2 and S20.

Apart from phone charging the GVEP supported entrepreneurs also provide other services such as barbershop (using electric clippers) and TV viewing. The 2014 World Cup had a big following in Tanzania  and one entrepreneur in Sakwe invested in a satellite service so he could show matches in his front yard. His neighbours paid a small fee to watch.

GVEP aims to help 550 businesses in total become established and profitable in the Mwanza region by Sept 2015. Currently there are 336 active businesses in the project and 98 more waiting to get started. Because the equipment costs around $400 some of the entrepreneurs need to borrow from a bank. This is challenging to do on their own but with GVEPs support almost 80 enterprises have secured loans with more in process. Eleven entrepreneurs – ten of them women – received their loans while I was in Mwanza recently. From the bank they went with the GVEP technology mentor to a reputable supplier Zara Solar to buy the equipment they needed.

It was like a party in the shop, everyone excited to be getting the equipment they know will transform their businesses. All of the entrepreneurs supported by GVEP receive business training and mentoring to ensure that by the end of the project they have the technical and business skills to prosper.

Are distributed energy service companies the future?

18 Jun

Historically the strategies of national governments in countries where people lack access to electricity have focused on grid expansion. The approach of the government of Kenya for example is primarily about lowest cost options for increasing generating capacity to feed the expanding national grid.

But alongside grid development we’re seeing a significant shift in donor thinking, with ‘off grid’ becoming an increasingly important focus. The US have a substantial ‘off grid’ component in their Power Africa programme, the UK has a new ‘green mini-grids’ programme soon to launch, the International Finance Corporation are embarking on major studies, and GIZ and KfW are supporting a range of programmes. Other funders are following suit.

Approaches differ and the paradigms are still evolving, but there is increasing interested in some quarters in the potential of commercially managed mini-grids. A recent paper by Pepukaye Bardouille and Dirk Muench from Persistent Energy describes well the potential these distributed energy service companies represent.

As Barbouille and Muench make clear DESCOs are still in their infancy. None have so far reached profitability. The business models look promising though, as GVEP can attest from our work with a number of the companies pioneering these approaches. The large amount of donor funding starting to flow into this area has the potential to help many of these businesses reach commercial scale.

Two issues which Barbouille and Muench don’t discuss in their paper are government policy and social equity. Few governments in Africa have policies which positively encourage and support DESCOs. This is not surprising considering the ‘early stage’ of the industry.

But supportive policy will be needed. Identifying suitable sites for deployment free of the risk of a competing grid extension is difficult and costly. GVEP recently commissioned studies for two sites in Tanzania which showed that a solar mini-grid could be viable. But government plans to extend the grid into the area led us to advise against a mini-grid. DESCOs need a clear national planning framework to operate within, and help with identifying good sites.

The social equity issue is a tougher one to crack. DESCOs can potentially operate on a purely commercial basis though in many African settings margins are thin. Avoiding reliance on subsidies clearly has benefits for a DESCO. But will governments support a two track electrification approach where the rural poor pay a lot more per kWh for electricity than those connected to the national grid. Fee for service models rather than a tariff are a way of avoiding direct comparison with the grid – but the underlying issue of ‘social equity’ is still there.  Why should the urban elite benefit from investments in infrastructure which are subsidised while the off-grid community receives no support?

Much work remains to be done on policy and strategy issues in individual countries before DESCOs find themselves in an environment which positively supports their growth. But there can be little doubt that this is an area where we will witness major change in the next few years.


Best practice in micro-grid development

14 Apr

In the last few years interest in non-grid-based options for rural electrification in has been growing. Falling solar PV prices partly account for the shift in mind set, as do advances in gasification technologies and the promise of small concentrating solar power systems. Mobile enabled applications for fee collection and system monitoring are also part of the evolving picture.

Recognising the potential, an increasing number of developing country governments are adopting policies which encourage the development of micro-grids either as permanent or temporary solutions. And the private sector is increasingly looked to as  the provider. All of this appeals to donors looking for better returns on their aid. Micro-grids, of course, have existed for decades but their deployment by for profit businesses operating at scale is new. So what’s working and where is the sector going?

Microgrids for Rural Electrification: A critical review of best practices based on seven case studies, published in February by the UN Foundation, is a useful summary of the current issues. The researchers document case studies from India, Malaysia and Haiti, including for-profit, part subsidised and fully subsidised models. A critique of existing ‘best practice’ literature is presented based on the findings. The report is by a team of US academics led by Jay Apt at Carnegie Mellon University and  Daniel Kammen at University of California, Berkeley.

As might be expected, the authors find that success factors vary from context to context. But they do identify a matrix of common factors which need to be managed by any developer of a service. Where these elements are controlled operators can create a ‘virtuous circle’ where revenue supports maintenance and enhancement of the service thereby encouraging customers to continue paying.

There is much agreement with previously published advice from bodies like the World Bank, but also some interesting new insights. Affordable, incrementally expandable micro-grids are hard to design and difficult to finance through revenues alone. This means that managing demand, including reducing losses from theft, is an important element of the economics of most micro-grids. There is no easy way of managing this currently and room for innovative new approaches.

The report questions the widely held view of many in the sector that encouraging ‘productive use’ helps improve the economics of micro-grids. The evidence suggests that having a number of anchor customers is vital, and where demand for power for commercial activity already exists this should be planned for. However, actively simulating ‘productive use’ where demand does not exist is likely to be difficult and time consuming.

The existing literature on micro-grids also puts great emphasis on the importance of involving communities, partly because much previous effort has focused on community managed facilities. The report’s authors suggest that community management models often fail and that with the growth in private business led delivery attention needs to shift towards customer education.

The report lacks examples from Africa, but the authors promise that these will be forthcoming soon.


Assessing the Suitability of Briquette Use for Households in Kenya

4 Dec

“I only ever heard about briquettes the day I was given some to use by GVEP” says Ruth Odhaimbo, a wife and mother of three living in Kariobangi, Nairobi.

Ruth is a business woman who participated in the recent research we conducted on the suitability of briquettes for use by the household market. Empirical evidence, including findings from a recent assessment of the briquette sector commissioned by GVEP, suggested that challenges exist for briquette adoption in the household market including their ability to meet consumer expectations and the availability of distribution networks. To gain a better understanding of the use of briquettes within households, a briquette suitability assessment study was carried out so as to understand how well briquettes burn in commonly available cook stoves, their suitability to common household cooking tasks and what consumers like and dislike about their use.

Interviews were conducted with stakeholders in the biomass sector including biomass briquette manufacturers, organisations that are running briquette initiatives and households that used the biomass briquettes.

Samples of briquettes were given to households in Kariobangi, a low-income residential estate in northeastern Nairobi, Kenya. It consists of both apartments and slum-type dwellings. Kariobangi area was chosen to be area of study because of the middle – lower class residents that stay there, these families are more likely to use the Portable charcoal stoves as evidenced by the numerous numbers of charcoal vendors in the area. This means that people in the area are paying for fuel and therefore there is a likely market for briquettes in the area.

The households were observed over a six-day period as they used two different types of briquettes provided for the study, that is, ball briquettes and Sausage Briquettes

The women had both positive and negative observations about the use of briquettes as summarized below:


  • The briquettes burn for long and therefore last longer
  • They have a high heat Intensity
  • They have less smoke and hence can be used inside the house
  • They do not spark and are thus clean to use in the house
  • They are economical and affordable
  • Effects to health experienced were less compared to charcoal use that causes coughing and headaches when used in areas of low ventilation.


  • The briquettes are hard to light
  • They produce a lot of ash
  • They are not able to keep the fire going if any more are added during cook time
  • Their usage requires more time, thus they are not suitable for quick cooking tasks

The study showed that the most common types of fuel currently used in the households were charcoal and kerosene and the most common cook stove was the Kenya Ceramic Jiko. The briquette technology was not common in the area during the time of the study but the response towards it was positive. Most respondents felt that the positive aspects of the fuel outweighed the negative and they were willing to take up the technology and use it daily. A few individuals were interested in doing a briquette retail business in their neighborhood.

Based on the analysis of the findings, the assessment went on to make the following recommendations:

  • If households are to substitute more of their fuel use to briquettes, there needs to be a technological improvement on the kind of stove to be used with briquettes as the fuel. However it remains likely that briquettes will still be used in conjunction with traditional charcoal, so, a stove that burns both fuels efficiently would present the ideal option.
  • There needs to be further research to see how briquettes can be made easier to light and have lower ash content.
  • There should be improved briquette commercialization such that briquettes are advertised in various residential areas and are made available for purchase and use through the establishment of retail networks. Retail networks such as those being established by organizations like Living Goods could help to make briquettes more available to households.
