We have a global DNA

Infra Futura

Women ont he roofs WS
Team Ghama

Stella Futura was founded in 2018 with the vision of building a sustainable financing model for green electrification of healthcare and industry in West Africa.

In 2023, a new company called Infra Futura was formed to continue the African operations. Infra Futura now has installations and operations in multiple African countries, with a strong focus on healthcare electrification.

Within the African operations, Stella Futura's founder, Ulrika Tornerefelt, has launched the Women on the Roofs initiative, where Infra Futura trains women to become solarpreneurs. This means that local women are trained in solar installation, service, and maintenance. These women thus receive long-term employment throughout the lifespan of the projects, which can be up to 20 years.

Successful collaborations have been established with, among others:

  • The Swedish Energy Agency, where Infra Futura is the only Swedish company included in an ITMOs program through Paris Article 6.
  • CAKE, where Infra Futura integrates CAKE's electric motorcycles into the healthcare electrification program, enabling the transportation of blood and vaccines to rural areas far beyond hospitals and healthcare facilities.
  • Medical Mission, where Infra Futura incorporates guarantees into the financing model for hospital electrification to reduce capital costs for the end user and make the model sustainable in the long term.
