According to the World Bank, approximately 1.1 billion people, mostly in sub-Saharan Africa and developing Asia, live without electricity today. Working Group B3.43, convened by Perry Tonking from Australia, was formed to support efforts to electrify regions where significant challenges exist in developing infrastructure. The objective was to identify opportunities and provide guidance to lower the cost and risk, while improving the efficiency of deployment of substation assets in developing and remote regions. It has now published Technical Brochure 740, titled “Contemporary design of low cost substations in developing countries. Other Australian members of the working group were T Kreig, R Adams, R Hughes, N Arora and A Gabriel. While the focus was on developing countries, all of the recommendations in the Technical Brochure are relevant for developed countries. A number of cases in South Africa and Brazil may be quite relevant in Australia and New Zealand where composite technologies and modular type developments could strip out significant cost.
