About Us


Corporate Overview

Joule Africa is engaged in the development and operation of sustainable energy projects across Africa with offices in London, Freetown, Yaounde and Port Louis.

Joule Africa is currently developing renewable energy assets in Sierra Leone and Cameroon, whilst simultaneously seeking to assist with the development of further projects throughout sub-Saharan Africa.

Joule Africa puts sustainable development and transparency at the heart of its business practice. The company works closely with all of its stakeholders to create infrastructure assets that will generate long-term value. The organisation is dedicated to working closely with host Governments to help deliver projects that complement existing plans for social and economic development.

Through the development and operation of sustainable energy assets, Joule Africa is committed to significantly increasing access to energy for the nations in which it is needed most, a fundamental factor in any country’s ability to develop.

Our Approach

Energy is an essential requirement for the continued growth of any economy. However, in sub-Saharan Africa, 70% of the population has no access to electricity. Joule Africa is dedicated to combatting this barrier to economic advancement by developing key energy assets in under-served African regions.

Joule Africa recognises that long-term success will only be possible if all stakeholders benefit; as such, sustainable development and transparency for the benefit of all of our stakeholders are at the heart of our business practice. We believe that positive social development, environmental stewardship and close consultation with local communities should sit at the forefront of any development.

We believe that positive investment in local communities and a sensitive approach to the environment are the best way to ensure a positive, long-term return for every stakeholder in the project.

Positive Social Impact

Joule Africa is committed to ensuring that any plans for social development are carried out in conjunction with local organisations with proven expertise. These strategic partnerships help achieve needs-based responses to pertinent social issues with the maximum level of impact.

Joule Africa is committed to realising positive social change alongside the communities in and around which it works.

Joule Africa is also dedicated to stimulating local economic growth by hiring local labour and purchasing local materials wherever possible.

Open Communication

Transparency and open consultation are at the forefront of all of our engagement with the community, as well as our government partners, observed through strict adherence to IFC Performance Standards. This includes, but is not limited to: regular consultation with community leaders, facilitation of focus groups at both village and district level; and support for local cultural activities.

Joule Africa is committed to ensuring that the communities with which we work gain a sense of informed involvement in the development process.

Environmental Stewardship

Environmental stewardship is essential to the long-term sustainability of any major infrastructure development.

Environmental & Social Impact Assessments are conducted for all projects in accordance with both the World Bank Operational Policies and the IFC Performance Standards based upon the Equator Principles. These international standards are at the core of Joule Africa's stewardship policy, aiming to not just meet, but to exceed them wherever possible.
