This has both increased the cost-competitiveness of off-grid technologies and broadened the range of technologies available to satisfy different energy needs (table 3.1). Increasingly, larger SHSs are also being used by community facilities, such as schools and rural health centres in unelectrified rural areas (Bhatia and Angelou, 2015). However, policies have also played a critical role, particularly through awareness-raising, quality-assurance programmes, grants and soft loans, and tariffs and tax reductions (Scott and Miller, 2016, Africa Progress Panel, 2017).15 While by no means transformational, household ownership of basic energy systems can provide meaningful savings and welfare improvements.
