There are two initial challenges indefining and measuring energy access: the absence of auniversal definition of energy access and the difficulty ofmeasuring any definition in an accurate manner. Themulti-tier approach to measuring energy access proposed inthe Sustainable Energy for All (SE4ALL) Global TrackingFramework of 2013 introduces a five-tier measurementmethodology based on various energy attributes, such asquantity, quality, affordability, and duration of supply.The approach makes it possible to compute a weighted indexof access to energy for a given geographical area. Separatenotes focus on multi-tier measurement of energy access forhouseholds, productive enterprises, and communityinstitutions. The type of data required for a multi-tieredassessment of energy access in a given area can be obtainedthrough surveys of actual energy availability and use amonga scientific sample of all users in a given category(households, enterprises, community institutions). Surveyquestionnaires elicit information about each energyattribute, and the results are fed into the multi-tiermatrices. Data may also be collected from energy suppliersto indicate the tiers of access that specific projects maydeliver to a targeted population. Capturing themulti-dimensionality of energy access is important, becauserapid expansion of access to energy requires both accurateassessment and tracking of progress. Under the newmulti-tier framework, data from energy surveys are compiledand analyzed to produce an energy access diagnostic for agiven area. The diagnostic includes an in-depthdisaggregated data analysis and an aggregate analysiscomprising a series of indices of energy access. Definingand measuring energy access by considering attributes ofenergy supply yields a better understanding of how variousinterventions improve access.
