Sustainable energy supplies have been a key to economic development and the transition from agricultural economies to modern industrial and service-oriented societies. Energy as essential to improved social and economic welfare is a key for reducing poverty and raising living standards. However, still 1.2 billion people have no access to electricity [1] and providing sustainable energy access to these people is a real challenge. How Rwanda is performing in terms of providing sustainable electricity to its rural people? This thesis evaluates the relative performance of Rwanda from 2009 to 2013 in providing sustainable electricity access. The evaluation of sustainability of electricity access situation was undertaken using Principal Components Analysis technique (PCA) whereby a theoretical framework defining sustainability of electricity was constructed and a set of indicators has been selected basing on analytical soundness, measurability and ability to describe electricity sustainability phenomenon and also basing on the availability of data to define and determine the sustainability. The study shows that the sustainability for electricity access in Rwanda has been improved for the evaluated period of time (2009-2013). The results conclude that the sustainability of electricity access situation has gone up and this is due to the introduction of many programs that have been instigated and Government commitment to improve the electrification rate. Some strategies, commitments and laws such as electricity law, National energy policy and national energy strategic plan; economic development and Poverty Reduction Strategy as well as Renewable Energy Feed In –Tariffs and electricity access roll-out program that were executed in these period seems to be instrumental in achieving better performance in terms of electricity sustainability.
