How technology could help rural South Africa turn sunshine into income

A decentralized energy system also requires an

a

exchange mechanism to link buyers and sellers. In South Africa, the state utility Eskom currently fulfills this role. It effectively acts as a central clearing house. It does this by buying electricity from renewable power projects, adding it to its own generated energy and selling it to consumers.

But there are technologies being developed that could do away with the need for a clearing house like this. One is a distributed ledger technology, of which blockchain is an example. The use of this technology would allow small-scale transactions between buyers and sellers to be captured and recorded. In this way, it could facilitate the development of small-scale electricity trading markets.

Blockchain has been identified as one of the pivotal technologies alongside Artificial intelligence, Internet of things and Big Data. Interest in applying the blockchain technology to energy markets is slowly picking up.
