Energy As It Should Have Always Been

We’ve made it our mission to provide green electricity for all. By leveraging tech, we keep things lean and simple, allowing us to focus on our customer’s needs and stay 100% green — without needing to markup our tariffs like other providers.

Flexible & Fair

We sell our energy at cost because we'd rather our customers consume less, instead of more.
