Powering Villages Today – Building and Operating an off-grid mini-utility system
Description: In 2018 the World Bank committed $1.4 billion for energy access programs, with $600 million toward mini-grid and off grid electrification; 78% of which designated for Africa. This money, combined with $1,066 million in private sector and government support, is driving the introduction of 2,200 World Bank planned mini grid projects. In addition to World Bank support of this energy sector, there are a multitude of small, medium and large scale projects underway with private, venture, angel and other capital infusions.
This tutorial will begin with a brief introduction to the exploding world of islanded mini grid installations followed by a deep dive into the design, technology, deployment and operation of small-scale micro utilities within the Africa context. The day’s class will round up with real-world case studies and testimonials from IEEE Smart Village in-country “energy entrepreneurs” and project managers. This all-day tutorial kicks off with the “why” mini grids are the future of distributed energy service…. Followed by the “how to” build and plan your micro utility… ending with “what I did” by genuine practitioners.
Hands on activities include introduction of the IEEE Smart Village SunBlazer IV, the next-generation product in the series with scalable features designed to provide reliable sustainable energy solution to off grid communities around the world. A mobile solar 1,800W to 3,600 W base station with portable battery kits for home lighting.
