Supporting Thermal Energy Services in Afghanistan

Binu Parthan from Sustainable Energy Associates writes on the growing support for thermal energy service considerations in Afghanistan.

Afghanistan is often in the news for the wrong reasons such as large swathes of migrants on European shores, armed conflicts, loss of life etc. However it is possible that the country might actually be implementing one of the most innovative energy services projects which has just started implementation with support from the STEPs team.

Decades of political instability and conflict has resulted in low levels of infrastructure access levels in Afghanistan. Over 57% of the Afghan population does not have access to electricity and 81% of the population does not have access to non-solid fuels (World Bank/IEA, 2015). The situation is dire in rural Afghanistan where only 4% of the population have access to non-solid fuels. Many such locations in Afghanistan are located in colder regions with more than 6000 HDDs/Year.

Afghan households use a Tandoor, a traditional cylindrical clay or metal oven for cooking and baking an efficient version of which is shown in the Fig. It is reported that 90% of cooking revolves around making bread called Naan, followed by potatoes. Houses also use a Bukhari, a traditional space heater for heating the living spaces in winter. Some of the traditional houses also have a Tawa Khana which circulates the hot combustion gases from the tandoor under the floor of the living room and releases to the outside through the opposite wall.

Households in Afghanistan use firewood, animal dung cakes, charcoal and shrubs for heating and cooking. Traditionally firewood and charcoal were purchased in rural Afghanistan but increasingly shrubs and animal dung cakes also have to be purchased. The thermal energy use of solid fuels also have their serious health effects, the annual number of pre-mature deaths from indoor-air pollution is estimated to be 54,000/Year (WHO, 2009). In comparison the civilian casualties in 2015 from the armed conflict in Afghanistan was 11,002 (UNAMA, 2016). The use of solid fuels are also a financial strain on the Afghan households as the average rural Afghan household spends over $ 90 on fuels of which only 12% is on kerosene/lighting with 88% on thermal energy. The prices of the solid fuels also increase by 15-25% during winter months as well.

Since late 2013, since the inception of the STEPs project, till late 2015, Sustainable Energy Associates (SEA), one of the partners have been working with the Ministry for Rural Reconstruction and Development (MRRD) in Afghanistan and UNDP to develop a project to address these rural energy and thermal energy challenges. These efforts have led to development of a new programme – Afghanistan Sustainable Energy for Rural Development (ASERD) which has business model and financial innovation at the core of the programme design and was finalised by SEA in late 2015. The project agreement was signed by MRRD and UNDP in late December 2015 and will be financed by the governments of South Korea and Sweden. The project will have a financial outlay of over US$ 50 million and will be implemented over 4 years during the period 2016-2019.

The ASERD programme plans to establish sustainable rural energy services in 194 rural communities in 4 years, providing both electrical and thermal energy services. The efforts will bring sustainable energy to over 19,500 households providing health, economic and social benefits. However the major contribution the programme will make to rural energy in Afghanistan would be to establish delivery models that are technology neutral, leverage additional local and international resources, mobilise communities, engage the private sector and financiers to establish a self-sustaining delivery model. The thermal energy service model which will be used by ASERD is shown in Fig.1.

Past rural energy programmes in Afghanistan have mainly relied on technology driven approaches which have focused on commissioning electricity generating equipment and transferring ownership, operation and utility management responsibilities to the communities. These efforts have also largely ignored the cooking and heating needs of rural population in a country which has cold winters. The opportunities to go beyond household energy to commercial, enterprise and public service use of energy have not been exploited or capitalised effectively. Similarly private sector and financial institutions have only played a limited role in the programme so far and the aspects of policy, regulation, standards and incentive frameworks have also not received considerable attention.

Against this backdrop, the ASERD programme seeks to graduate from the current approach to establish a technology-neutral, sustainable service delivery arrangement to provide thermal and electrical energy in rural areas of Afghanistan for household, social and productive needs. The programme will also provide energy in rural areas to seek agriculture productivity gains, rural enterprise development, income generation, community social empowerment and cohesion as well as to expand public service to improve access to better health, education and security in rural areas. To deliver these services in rural areas in a sustainable manner the programme will seek to engage the national utility and the private sector in addition to community mobilisation.

The programme will also develop capacities of the government agencies, civil society and the, private sector including the financial sector. ASERD will also create frameworks for policy and regulation, testing and quality assurance as well as will also pilot seven innovative energy service delivery models which will leverage skillsets and resources from communities, private sector and financial institutions some of which are linked to global financing mechanisms for climate change and energy. These models will also result in benefits to women and the marginalised nomadic Kuchi communities.

The design of ASERD has benefited from the learnings on thermal energy services offerings, key challenges and solutions gained by the STEPs project team which will now be used to support about 20,000 families in Afghanistan. SEA will be involved during the implementation of ASERD to support MRRD and UNDP.

The Emerging Impacts and Evolving Development Framework for Thermal Energy Services

Binu Parthan of Sustainable Energy Associates writes on developmental frameworks and the emerging sphere of thermal energy services in them.

When the STEPs project received the nod from EPSRC and DfID in 2012, energy access in developing countries was all about electrification and Cookstoves. The assumption was that if you provide an efficient biomass Cookstove to a household and the thermal energy access problem was solved. So lot of the focus in 2012 was on cooking and Cookstoves. Efforts then were essentially focussed on developing more efficient Cookstoves and reducing the cost of Cookstoves. In addition to Biomass Cookstoves, there were also efforts which were focussed on solar cooking focussed. So the space was divided between different technologies and limited to biomass and solar energy technologies.

When STEPs project was proposed in 2012, where we encouraged to consider thermal energy as a service for cooking, space and water heating and applications, the typical reaction was that it was a just another Cookstoves project. Often the challenge was that people – both practitioners and researchers had not heard about the concept and were often quick to dismiss it. Another challenge was when we advocated technology neutrality meaning that the thermal energy services may be delivered through renewables, LPG or electricity there was certainly a lot of discomfort as if was always been about Cookstoves and technologies. There were also suggestions that cooking technologies should be limited to renewable energy and LPG was fossil fuel based and was not an option for developing countries etc.

The STEPs project team has since made a number of efforts to increase awareness about the need to look at thermal energy as a service rather than a product. We spoke at several events that had linkages to the energy access agenda and targeting development agencies and governments. Our team reviewed and commented on the Sustainable Development Goal (SDG) drafts and objected to the emphasis on Cookstoves in the earlier drafts. We also emphasised the need for considering space heating and sanitation energy needs and the need for technology neutrality.

We also carried out a questionnaire survey during second half of 2014 to early 2015 with 2 objectives 1) to popularise the project and the idea of thermal energy services and 2) to gather data for the project outputs. The questionnaires that were sent out to 64 experts drawn from development agencies, practitioners and researchers with response collected through Survey Monkey, response forms and through phone interviews. The STEPs team also held discussions with two South African rural energy enterprises to encourage them to consider an energy service offering. We reviewed and commented on the Global Tracking Framework (GTF) and the multi-tier framework for energy access for the UN’s initiative on Sustainable Energy for All (SE4All).

We also continued to look for opportunities to pilot the STEPs model in an actual implementation context and continued our discussions with United Nations Development Programme (UNDP) and Lesotho. It was important for us that STEPs as an effort to go beyond a collection of publications and outputs to an effort which will make a tangible impact on public policy as well as thermal energy use in developing countries.

Now with the project in its third and final year we are seeing the impact of the some of our persistent efforts:

  • The current and final text and the background narrative on SDG 7 on energy talks about cooking and heating and the targets for SDG 7 is technology neutral, silent on technologies and talks about energy services. The final target reads as ‘By 2030, ensure universal access to affordable, reliable and modern energy services’. As the global development agenda on energy during 2016-2030 will be guided by the SDG framework, this will allow a level playing ground for thermal energy services and hopefully attract more resources to support thermal energy services in developing countries;

  • The SE4All GTF update in 2015 is more technology neutral and includes space heating. The multi-tier frameworks also place an emphasis on service, fuel supply etc. and a new multi-tier framework has been included for space heating. As the GTF and multi-tier framework is likely to be used by World Bank and other development agencies for energy access projects/programmes, this may support the implementation of more thermal energy access initiatives.

  • We have had one South African private enterprise – AES requesting the project for business advice on offering an energy service business proposition;

  • Responses from 32 out of 64 organisations to the questionnaire survey including development agencies such as World Bank, IFC, UNIDO, UN-ESCAP, GIZ practitioners such as NuRa Energy, Practical Action, Selco, Simpa, BGF, S3IDF, ECS, ACE, practitioner networks such as GVEP, GACC, Ashden and energy research organisations such as IIASA, Imperial College, Stellenbosch University, TERI etc and the World LPG Association. Many of these organisations expressed a desire to be updated on the STEPs project details.

  • Although we faced delays in implementation with the UNDP Lesotho project where we wanted to integrate the STEPs model for thermal energy services, we have managed to integrate the STEPs thermal energy services model into a much larger project in Afghanistan. The project which began implementation in 2016, will implement the thermal energy services model in about 200 villages benefitting about 20,000 households;

During this final year in 2016, we will continue to focus on disseminating results from the research and deepening our influence and impacts with actual on the ground projects.

What Could The Energy Transition Be for Thermal Energy Services in the Global South – Part 2

Following our previous post on cooking, this post will investigate space and water heating/space cooling needs.

Space and water heating/space cooling

Heating can be an important source of energy consumption in a number of developing countries located far from the Tropics. This function is often associated with cooking, where a central heating point is used both to cook meals and heat the house. Bio-digesters in countries like China, India or Nepal have been able to provide heat on top of cooking.

Another energy service which is more widely used – even if often not considered as a priority – is domestic hot water which can be provided with a solar water heater. South Africa has some very large programmes of dissemination of solar water heaters, notably in townships. Half of the population of Barbados has a solar water heater. Solar water heaters are a mature technology, which can be easily manufactured locally and relatively cheaply, most of the time sold on a cash basis or with a consumer credit.

Cooling renewable energy technologies are less available. For instance solar thermal cooling systems seem to exist mainly as large-scale technology; they tend to be complex to design and generally are quite costly. They are not considered in the STEPs project, which deals with the large-scale dissemination of medium scale collective or individual small-scale mature technologies.

Heat pumps imply dwellings of good quality with good insulation which is not a common occurrence in the case in poor communities.  Nevertheless ground-source heat pump could potentially be used at a larger scale (http://unu.edu/publications/articles/geothermal-energy-in-developing-countries-and-the-mdgs.html).

Insulation

Energy-efficient insulation and passive housing have traditionally been the preserve of developed nations (for example, the developed German passive housing technology sector). However, the potential for efficient insulation and space temperature management with locally-sourced, low-cost renewable materials has been realised in a number of countries, particularly in Sub-Saharan Africa. This includes both traditional methods for adapting households in temperate developing countries, such as cladding and thatch roofing, as well as the more modern concept of passive housing, where thermal energy inputs (for example, from the sun) are used as part of the building’s thermal energy regime, enabling a reduction in the use of air conditioning methods.

Traditional housing for example in Lesotho is adapted to the variable temperatures of the mountain climate the country resides in, with rondavels (traditional huts) having conical thatched roofs and daubed exterior walls for insulation against the often cold climate, and warm air retention.

Business model examples and projects for efficient insulation in developing countries are few and far between. For instance, the iShack project in Enkanini, an informal settlement in Stellenbosch, South Africa in partnership with the University of Stellenbosch, is predominantly a fee-for-service solar home system project, where users pay a small monthly fee on top of a fixed installation cost for small (50-80W) solar home systems. However, the organisation is also expanding into sustainable insulation and other household services, particularly sustainable wastewater treatment and household-scale biogas installations for cooking.
