Introduction
Energy Access used to be defined by whether or not a household had access to electricity or not. However, this over-simplistic criteria ignores the many forms in which people access and use energy. For example, many grid connected household only have access to electricity at a low voltage or their supply might be intermittent and therefore restrict their electricity usage to only a few hours a day. Also, defining energy access through grid connection does not take into account these energy needs for cooking and heating, which are often met through solid or liquid fuels, rather than through electricity. A further factor which needs to be considered in terms of energy access is the availability of energy for businesses, community institutions, such as schools, health facilities, government buildings, public buildings as well as street lights.[1] In order to take into consideration these numerous different factors, all of which contribute towards energy access, a more holistic framework for measuring and defining energy access was needed.
The Global Tracking Framework and the Multi-Tier Framework
The Multi-Tier Framework (MTF) for measuring energy access was first introduced in the 2013 Global Tracking Framework (GTF) report, written by the World Bank’s Energy Sector Management Assistance Program (ESMP) together with other organisations and programs including Energizing Development, Lighting Africa, Practical Action, The Global Alliance for Clean Cookstoves, the UN Development Programme, the UN Industrial Development Organization, the World Bank, and the World Health Organization.[2] The MTF was developed within the Sustainable Energy for All (SE4ALL) initiative, due to the shortcomings of a binary energy access assessment, in which a household was either defined as having access to electricity or not. The aim of the framework is to “to monitor and evaluate energy access by following a multidimensional approach.”[3] This is done by measuring energy access using a multi-tiered-spectrum which ranges from Tier 0 (no access) to Tier 5 (the highest level of access).[3] The data gathered through the GTF can then be used to measure global progress towards the United Nations (UN) Sustainable Development Goal 7 (SDG7) which aims to achieve universal access to affordable, reliable and modern energy services by 2030.[4]
The four main objectives of the MTF are to:
- “Establish a global baseline of energy access, starting in 10-15 high access deficit countries based on the multifaceted definition according to MTF;
- Transfer capacity to national statistical offices to keep tracking progress toward SE4ALL goals and SDG in the future and
- Continue improving tools and capacities for tracking progress towards reaching the SE4ALL objective of universal access to modern energy services by 2030, based on MTF and;
- Provide reliable data on energy sector that can meet needs of multiple stakeholders, including government, regulators, utilities, project developers, civil society organizations, developmental agencies, financial institutions, appliance manufacturers, international programs and the academia.”[4]
The GTF includes three main sections. One for assessing household access to energy, one for assessing the access to energy for productive engagement and one category for assessing the access to energy for community facilities. Energy access for households is further divided into access to electricity, cooking solutions and space heating. Access to energy for community facilities looks at street lighting, health facilities, education facilities, community buildings and public offices.
An overall energy access level for households/productive use/community facilities can be obtained by calculating the average tier based on all of the individual categories within each index. Further data analysis could combine the results to calculate the average energy access level of a neighbourhood or region, and then comparing it to other regions or tracking the progress of that region over time.[1]
Household Energy
Access to Electricity
In the GTF household access to electricity is measured based on the capacity, duration, reliability, quality, affordability, legality and health and safety impacts. The criteria are technology neutral and focus only on the impacts for the consumer.[1] Table 1 below shows how the different tiers for access to household electricity supply are determined within each category. In order to determine the overall energy tier of a household the average of all tiers is calculated.

*The minimum power capacity rating in Watts are indicated, particularly for Tier 1 and Tier 2 as the efficiency of end-user appliances is critical to determining the real level capacity and thus the type of electricity service that can be performed.
While usually having good access to electricity supply results in a better access to energy services the two do not necessarily come together. A household could have good electricity supply, but not have access to household appliances, or vice versa. Therefore, Table 2 shows a separate multi-tier matrix for measuring a household’s access to electricity services.

Access to Cooking
The GTF measures household access to cooking based on the indoor air quality, cookstove efficiency, convenience, safety of the primary fuel, affordability, quality of the primary fuel and the availability of the primary fuel.
Table 4 shows the matrix used for accessing access to cooking solutions. “Although distinct, the multi-tier framework for household access to energy for cooking has been defined in a manner that is consistent with the International Workshop Agreement on Cookstoves (IWA) tiers for measuring cookstove performance. To avoid any confusion with the IWA “tiers” for cookstoves, the proposed multi-tier framework uses the term “levels” for improving echelons of attributes of cooking access.”[1]

Access to Space-Heating
In many households, space heating is achieved through the same means as cooking. However, space heating is also often achieved (or augmented) through additional heating systems such as electric heating, fuel-based centralized district heating, fuel-based standalone heating, and direct solar heating. Therefor space heating has been assigned its own individual multi-tier framework, separate from the cooking framework. This allows for an individual access to energy for space heating index to be calculated, based on the categories shown in Table 5.[5]

Productive Use
“Productive uses of energy are defined as those that increase income or productivity, referred to as value-adding activities.”[1] This quite general definition makes is difficult to define an energy access framework for productive use, due to the many different types of energy requirements which might be encountered. The productive use framework shown in Table 6 was devised based on energy access experiences of individuals in productive engagements. It includes all of the major energy applications/impacts which were found to be relevant for productive use activities.[1]

Community Energy
Access to energy in community areas/facilities is very important for the socioeconomic development of a community. As an example, having access to energy can improve the quality of education and healthcare facilities by being able to power electric device, lights and heating systems. The huge diversity found in different communities in terms of their available facilities and resultants energy demands make it challenging to assemble a single comprehensive framework for community energy access. Due to this complex street lighting coverage energy access for community institutions have been assigned two separate frameworks. The multi-tier frameworks for energy access in community institutions (shown in Table 7) and street lighting (shown in Table 8) were devised based on surveys with community institutions, as well as community members using these institutions.[1]
