This volume is part of the Series of Energy Efficiency Guides of the Energy Division of the Inter-American Development Bank, whose publication responds to the lack of easily accessible information in Spanish. on issues related to energy efficiency in the countries of Latin America and the Caribbean.

Latin America has made significant progress in the provision of electricity, with an increase in coverage from 88 to 97% between 2002 and 2018. For the connection to be really useful it is also necessary that the service be reliable, but the improvements have not been so high

The distribution reliability indices and the factors that affect their calculations are defined in this guide. The indices are intended to be applied to distribution systems, substations, circuits, and defined regions.

Fundamental changes in electricity generation and use are requiring the electricity system to perform in ways for which it was not designed—requiring new capabilities and system designs to maintain historical levels of reliability.

The Brazilian Association of Electric Power Distributors (ABRADEE) is a non-profit private law civil society.

The Energy Community is an international organization which brings together the European Union and its neighbors to create an integrated pan-European energy market.

European energy regulators are committed to promoting well-functioning and competitive energy markets in Europe in order to ensure that consumers receive fair prices, a wide choice of suppliers and the best quality of supply.

This paper proposes a possible approach to providing differentiated reliability options to customers in urban and suburban distribution networks. To offer different reliability options based on customer's preferences, a utility can deploy distributed generation (DG), sectionalizing switches (Normally Closed Switches: NCSs) and tie switches (Normally Open Switches: NOSs). During power outages, DG, as backup generation unit, is a means of providing higher reliability to customers who require it.

Electricity grid vulnerabilities can lead to outages with prolonged load interruptions. Research activities on the impact of natural disasters on power system are underway to figure out the outage reasons, identify the ways to prepare for preventive actions, and increase the resiliency for the corrective and preventive actions under such scenarios.
