Hardware and Software
A battery management system (BMS) is the core electronic circuit of every modern Li-ion based energy storage system. It enables energy access companies to develop customised solutions including second life applications of used electric vehicle batteries, suitable for productive use appliances, mini grids, etc.
AirLink uses financed phones as relay-extensions of the internet in remote areas, to extend productive asset data coverage in even the most rural communities. By introducing open-standards communications, AirLink allows customers' phones and PAYGo assets to communicate between themselves and each other using widely available, standard low-energy Bluetooth connectivity.
Many Pay-As-You-Go (PAYG/PAYGO) systems are based on 2G/GPRS communications. But as 2G towers get replaced by 3G and 4G infrastructure, energy access organizations around the world will need to update their hardware. Okra's communications solution, Cicada, is an open source module with 2G, 3G, 4G, and WiFi capabilities.
Finance and Business Models
A Distributed Renewable Energy Certificate (D-REC) represents one kilowatt-hour (kWh) of electricity that has been generated from distributed renewable energy sources. It allows companies to sell the renewable energy attributes that originated from small installations, such as Solar Home Systems or mini-grids.
The AgriGrid business model refers to a hybrid organization that combines commercial opportunities in rural electrification with food & agricultural value chain development. The idea is that beyond providing electricity, an AgriGrid operator would also play an active role in providing access to market for a community’s food & agricultural products, resulting in healthier and increased revenue generation for the mini-grid operator.
