Our take
tem is a next-gen energy transactions company that changes the way renewable energy is bought, sold and powered. Rebalancing the playing field away from "Big Energy", tem creates affordable, traceable and smart energy transaction management tools.
The company provides businesses and consumers with access to the same financial benefits as Big Energy companies by distributing its own purchased energy to customers. Once they’re signed up, customers are matched with a suitable generator, and the tem platform helps execute contracts, take payments, and manage invoicing.
This is a truly disruptive concept, and is proving to be a successful one. tem currently processes over £50 million in direct transactions and saves millions for over 1000 UK businesses wanting to switch from traditional utilities tied to the wholesale market. Whilst UK consumers are notoriously hesitant to switch providers, recent soaring energy prices is luring many into giving it a go.
