SectorMost major industry classification systems use sources of revenue as their basis for classifying companies into specific sectors, subsectors and industries. In order to group like companies based on their sustainability-related risks and opportunities, SASB created the Sustainable Industry Classification System® (SICS®) and the classification of sectors, subsectors and industries in the SDG Investor Platform is based on SICS.

Business Model Description

Invest in the development of solar mini-grids for businesses, as well as in communities, and other public or private facilities, such as hospitals, also known as Distributed Energy Service Company (DESCO). A mini-grid is defined as a set of small-scale electricity generators and possibly energy storage systems interconnected to a distribution network that supplies electricity to a small, localised group of customers and operates independently from the national transmission grid. They range in a size from a few kilowatts up to 10 megawatts (12). While mini-grid energy generation technologies can include diesel generators as well as renewable sources, the business model specifically focuses on solar technology.

Expected Impact

Tackle energy poverty among those who do not have access to electricity, eliminate disruption to businesses from unreliable grid connection, while contributing to reduction of CO2 by replacing unsustainable sources of energy.

Indicative ReturnDescribes the rate of growth an investment is expected to generate within the IOA. The indicative return is identified for the IOA by establishing its Internal Rate of Return (IRR), Return of Investment (ROI) or Gross Profit Margin (GPM).
10% - 15% (in IRR)
Investment TimeframeDescribes the time period in which the IOA will pay-back the invested resources. The estimate is based on asset expected lifetime as the IOA will start generating accumulated positive cash-flows.
Long Term (10+ years)
Market SizeDescribes the value of potential addressable market of the IOA. The market size is identified for the IOA by establishing the value in USD, identifying the Compound Annual Growth Rate (CAGR) or providing a numeric unit critical to the IOA.
< USD 50 million
Average Ticket Size (USD)Describes the USD amount for a typical investment required in the IOA.
USD 1 million - USD 10 million
Direct ImpactDescribes the primary SDG(s) the IOA addresses.
Affordable and Clean Energy (SDG 7) Reduced Inequalities (SDG 10) No Poverty (SDG 1)
Indirect ImpactDescribes the secondary SDG(s) the IOA addresses.
Decent Work and Economic Growth (SDG 8) Sustainable Cities and Communities (SDG 11) Climate Action (SDG 13)
