    The Power of the Mine : A Transformative Opportunity for Sub-Saharan Africa
    (Washington, DC: World Bank, 2015-02-05) Banerjee, Sudeshna Ghosh; Romo, Zayra; McMahon, Gary; Toledano, Perrine; Pérez Arroyo, Inés
    Africa needs power - to grow its economies and enhance the welfare of its people. Power for all is still a long distance away - two thirds of the population remains without electricity and enterprises rank electricity as a top constraint to doing business. This sub-optimal situation coexists while vast energy resources remain untapped. One solution to harness these resources could be to tap into the concept of anchor load. Mining industry lends itself to the concept of anchor load as it needs power in large quantity and reliable quality to run its processes. Underpinned by a comprehensive database of mining projects between 2000 and 2020, this report explores the potential and challenges of using mining demand for power as anchor load for national power system development and expansion of electrification. This report finds that mining demand can indeed be a game-changer - an opportunity where policymakers and international community can make a difference in tapping the enormous mineral wealth of Africa for the benefit of so many people. The utilities would benefit from having mining companies as creditworthy consumers that facilitate generation and transmission investments producing economies of scale needed for large infrastructure projects, benefiting all consumers in the system. The mines would benefit from grid supply - typically priced much lower than self-supply - which allows them to focus on their core business, greatly enhancing their competitiveness. The country would benefit from more exports and tax revenues from mines, more job opportunities in local firms selling goods and services to the mines, and a higher GDP. The report estimates that mining demand for power can triple since 2000 going upto 23 GW in 2030. While South Africa will continue to be the dominant presence in mining landscape, its importance will reduce and other countries, primarily in Southern African region, will emerge as important contributers of mining demand for power. Simulations in countries with minimal power-mining interface suggests that bringing this demand explicitly into the power planning process can ensure more investments in both grid and off-grid power systems and potentially superior service delivery outcomes for mines as well as communities. These opportunities can also be attractive investment destinations for private sector. However, there are also risks and institutional roadblocks in power-mining integration - addressing many of them and employing risk mitigation mechanism are within the control of policymakers.

    Financial Viability of Electricity Sectors in Sub-Saharan Africa: Quasi-Fiscal Deficits and Hidden Costs
    (World Bank, Washington, DC, 2016-08) Trimble, Chris; Kojima, Masami; Perez Arroyo, Ines; Mohammadzadeh, Farah
    This paper studies the financial viability of electricity sectors in 39 countries in Sub-Saharan Africa using an approach similar to that in an earlier study, the Africa Infrastructure Country Diagnostic. The quasi-fiscal deficit in each country is calculated under two scenarios: existing utility performance and benchmark utility performance. In the first scenario, only two countries have a financially viable electricity sector (the Seychelles and Uganda). Only 19 countries cover operating expenditures, while several countries lose in excess of US$0.25 per kilowatt-hour sold. Quasi-fiscal deficits average 1.5 percent of gross domestic product, and exceed 5 percent of gross domestic product in several countries. In this context, it will be difficult for utilities to maintain existing assets let alone facilitate the expansion needed to reach universal access goals. The number of countries with a quasi-fiscal deficit below zero increases to 13 under the second scenario, and to 21 when oil price impacts are considered, indicating tariff increases may not be needed at benchmark performance in these cases. Combined network and collection losses on average represent a larger hidden cost and are less politically sensitive to address than underpricing, so could be a smart area for policy focus to reduce quasi-fiscal deficits. Underpricing remains an issue to address over the medium term, as service quality improves. With no changes in power mix, tariffs would need to increase by a median value of US$0.04 per kilowatt-hour sold at benchmark performance, representing a 24 percent increase on existing tariffs. Most countries have improved or maintained performance, and relatively few countries have had declining financial viability.

    Promoting Productive Uses of Electricity in Rural Electrification Programs: Experience from Peru
    (World Bank, Washington, DC, 2017-10-24) Franco, Janina; Bogach, V. Susan; Pérez Arroyo, Inés; Lasa, Maite
    Rural electrification programs can be more effective in stimulating economic growth, social development, and sustainable utility operations when they promote productive uses of electricity, as shown by a decade of experience in Peru. To obtain the desired benefits, rural electrification programs need to encourage and support installation and reliable operation of electrical equipment that makes production more efficient and profitable.
