The Company

RVE.SOL is a triple bottom line social entrepreneurship and mini-grid project developer. RVE.SOL leverages renewable energy and water purification technology within the context of sustainable community-led business models tailored to local needs. Through affordable PAYG energy and water services the company creates opportunity for creating jobs, empowering businesses and eradicating poverty in rural Africa.

The Challenge

Demonstrate a scalable village electrification solution to step-function social and environmental change, improving local living standards and enabling new services within the community including access to clean water, mobile phone charging, hair cutting, video hall and milk refrigeration.

Renewable Solution

Containerised KUDURA technology – a sustainable integrated solution encompassing RE generation, minigrid distribution, remote monitoring, PAYG service access and potable water production. Micro-grid reticulation after upgrade spans a total of 3,000 m and provides power to 47 small businesses and households. Total installed capacity: 7,5 kW PV – Current production level: 600 kWh/ month (AC).

Project Financing & Management

RVE.SOL has invested 87,000 USD in this pilot project to date, with a further 30,000 EUR raised through crowdfunding facilitated by www.jointrine.com. The project cash flows contemplate annual utility revenues of 17,500 EUR versus OPEX of 7,000 EUR generating average annual net cash of 5,000 EUR after expenses and debt service. Break-even is expected in 2020.

Project Outcome & Next Steps

Independent impact assessment in 2015 confirmed positive social and environmental impact after five years of operations:

  • 47% improvement in school grades;
  • 180% increase in girl-child school attendance;
  • 74% increase in disposable income due to reduced kerosene usage;
  • 100% increase in cassava yield (indirectly attributable);
  • 66% reduction in malaria infection (indirectly attributable).

Transition from pilot to market validation and commercialisation scale-up is currently underway. The business model centres around defining sustainable financial models tailored to the local environment in which they will function. This constitutes the ABC model + potable water production and other community entrepreneurial businesses to strengthen project cash flows and reduce time to break-even.
