Values

Real-time, real solutions

Efficient, effective customer service, built through motivated, well-trained employees and close collaboration with our investors, partners, contractors and suppliers.

Global experts, local knowledge

We envisage an Africa with electric power indices comparable to the developed world. Clean, Affordable, Reliable Energy — CARE — is what we do, achieved by understanding and breaking down the barriers standing in its way.

Idealist & realistic

Our way is to picture the ideal solution and adapt it to the real African environment — holding to international standards and processes while our risk analysis captures the challenges that are unique to the ground we work on.

Clients, suppliers & employees

Clients get the best value when we collaborate with our suppliers through fair market practices, and when we develop and motivate the people who deliver the work.

Our core services

From strategy to switched-on system.

Four services, one continuous line of accountability — we stay involved from the first conversation to the day your system is running and monitored.

We work with you to build a sustainability strategy that fits your goals, and support businesses bringing products to market or investing in energy projects in Africa.

03

Project management

We navigate the local terrain to manage your project start to finish — on time, within budget, and to the scope we agreed at the outset.

04

Training

Customised training programmes that give your employees and contractors the knowledge and skills to operate and maintain their renewable energy systems.
