Adequate Power

Off-grid solar home systems (SHSs) currently constitute a major source of providing basic electricity needs in un(der)-electrified regions of the world, with around 73 million households having benefited from off-grid solar solutions by 2017. However, in and of itself, state-of-the-art SHSs can only provide electricity access with adequate power supply availability up to tier 2, and to some extent, tier 3 levels of the Multi-tier Framework (MTF) for measuring household electricity access. When considering system metrics of loss of load probability (LLP) and battery size, meeting the electricity needs of tiers 4 and 5 is untenable through SHSs alone. Alternatively, a bottom-up microgrid composed of interconnected SHSs is proposed. Such an approach can enable the so-called climb up the rural electrification ladder. The impact of the microgrid size on the system metrics like LLP and energy deficit is evaluated. Finally, it is found that the interconnected SHS-based microgrid can provide more than 40% and 30% gains in battery sizing for the same LLP level as compared to the standalone SHSs sizes for tiers 4 and 5 of the MTF, respectively, thus quantifying the definite gains of an SHS-based microgrid over standalone SHSs. This study paves the way for visualizing SHS-based rural DC microgrids that can not only enable electricity access to the higher tiers of the MTF with lower battery storage needs but also make use of existing SHS infrastructure, thus enabling a technologically easy climb up the rural electrification ladder.

Remote Locations

According to the World Health Organization, nearly 3 billion people burn wood, crop wastes, charcoal, coal and animal dung to meet their day to day energy needs and among these nearly 1.3 billion people do not have electricity access. More than 80% of the population suffering from energy poverty are living in rural areas of developing countries, such as in East Africa. On the other hand, the potential of renewable energy resources in East African countries is huge. However, such resources are usually intermittent and therefore the use of renewable energy sources to provide modern energy access with a good reliability level, for the remote locations with lack of energy access, is still an issue. With this regard, one of the emerging technologies to solve accessibility of energy in rural and remote areas is DC-microgrids. This paper assessed the use of off-grid systems in different developing countries and presents the results in improving energy access, especially in rural and remote locations. The results indicate that the experience of some Asian countries and Tanzania in East Africa could be a good example for other East African countries to invest in off-grid systems and address energy access problems in their rural and remote locations. On the other hand, there are challenges related to financing and lack of trained man power in East African countries.

Improve Reliability

In Nigeria, an estimated 170 million people depend on less than 4,000 megawatts of electricity from the grid for economic and social needs. Since 2000 the country has embarked on an ambitious power sector reform programme, the main objective of which is to ensure adequate, available, and reliable electricity. The power sector reform adopts a neo-liberal development model that is based on the triple strategy of liberalization, commercialization, and privatization. This strategy has relied heavily on the reform of the existing legal regime of state institutions so as to attract foreign private capital to increase capacity, expand connection, and improve reliability. This chapter reviews the incompletely theorized neo-liberal assumptions in the reform policies and shows how these assumptions have undermined the efficacy of legal reform in the electricity industry and resulted in failed expectation.
