IEC TS 62257-1:2015

IEC/TS 62257-1:2013 introduces a methodology for implementing rural electrification using small autonomous hybrid renewable energy systems. It also provides a guide for facilitating the reading and the use of the IEC 62257 series for setting up decentralized rural electrification in developing countries or in developed countries the only difference being the level of quality of service and the needed quantity of energy that the customer can afford. The main changes with respect to the previous edition are as follows: - addition of a map and an up to date list of the current IEC 62257 series and a guide "how to use the IEC 62257 series" in order to implement a rural electrification project or a stand-alone hybrid system for a remote place in a developed country; - addition of a list of all the terms and definitions used in the series. This publication is to be read in conjunction with the IEC 62257 series.

IEC TS 62257-100:2022 introduces the entire series regarding off-grid renewable energy and hybrid products and systems most commonly used for rural applications and access to electricity. This document provides a guide for facilitating the reading and the use of the IEC 62257 series for setting up off-grid electrification in developing countries or in developed countries, the only difference being the level of service and the needed quantity of energy that the customer can afford. This document outlines the organization of documents within the updated IEC 62257-xxx series published in 2022 and later, including utilization of a new 3-digit part numbering scheme, grouped into topics and subtopics.
