EnAccess shares open source, innovative solutions for the energy access sector. These materials include open source software, hardware, and toolkit solutions that can help others save time and money.

Hardware and Software

Battery Management System

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.

OpenPAYGO Token

The OpenPAYGO Token is an open source token system to enable PAYGO functionality in new products. This system can be used by product manufacturers creating new devices and can be integrated with any PAYGO software platform.

Cicada

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 capability.

Finance and Business Models

The D-REC Initiative

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.

AgriGrid

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.

Operations

Survey Toolkit

Energy access organizations do a lot of surveying: of potential customers, sites, and marketplaces. Finding the best platform to manage this data can be hard. Devergy's solution, the Survey Toolkit, provides a simple approach to collecting, analyzing, and presenting field survey data.
