The GSMA has identified distributed ledger technologies as a key area of interest with the potential to transform existing business models for decentralised or off grid energy services in sub Saharan Africa and accelerate access to sustainable energy services. To this end GSMA's Mobile for Development Utilities division is currently seeking to better understand and evaluate the potential impact, applications, use cases, benefits and costs of distributed ledgers for energy service companies and customers, with the goal of leveraging its strategic partnership with the Department for International Development to resource future trials and to catalyse private sector investment. Working in partnership with the GSMA's Mobile for Development Utilities programme and ElectriCChain, developers of the SolarCoin Blockchain, this 24 month research project brings together a team of electrical and electronic engineers, human-computer interaction specialists, and social anthropologists to explore the potential for distributed ledger technologies to accelerate access to off grid solar energy in Sub-Saharan Africa.
