About Green Investment South Africa

Our Story
Green Investment South Africa was founded in 2010 by Dr. Thabo Ndlovu, a former economist at the South African Reserve Bank, and Sarah Bennett, an environmental scientist with extensive experience in renewable energy projects across Africa. They shared a vision of transforming South Africa's economy by channeling investment into environmentally sustainable ventures that would simultaneously address the country's pressing ecological challenges and create economic opportunities.
The company began with a modest R25 million fund focused on small-scale solar installations in rural communities across the Eastern Cape. The success of these initial projects, which provided reliable electricity to previously underserved areas while generating steady returns for investors, quickly attracted attention from both local and international financial institutions.
By 2015, Green Investment SA had expanded its portfolio to include wind farms in the Western Cape, sustainable agriculture initiatives in KwaZulu-Natal, and green building projects in major urban centers. This growth was fueled by a growing recognition among South African investors that environmental sustainability and financial performance could go hand in hand.
A pivotal moment came in 2018 when the company partnered with the Development Bank of Southern Africa to create the country's first dedicated green bond program, which raised R2 billion for climate resilience projects. This innovative financial instrument demonstrated how capital markets could be harnessed to address environmental challenges, and established Green Investment SA as a pioneer in sustainable finance within the African context.
Today, with over R8.5 billion in assets under management, Green Investment South Africa has grown from a small startup to one of the continent's leading sustainable investment firms, while staying true to its founding mission of creating prosperity through environmental stewardship.

Our Achievements
-
Renewable Energy Leadership
We've financed over 1.2GW of renewable energy capacity across South Africa, representing approximately 15% of the country's total installed renewable capacity. These projects provide clean electricity to more than 800,000 homes while avoiding 2.3 million tonnes of CO2 emissions annually.
-
Job Creation & Skills Development
Our portfolio companies and projects have created over 5,000 permanent jobs and 12,000 construction jobs across South Africa. Through our skills development program, we've trained more than 2,000 people in renewable energy installation, sustainable farming techniques, and green building practices.
-
Financial Innovation
We pioneered the use of green bonds in South Africa, helping to raise over R5 billion for sustainable projects. Our blended finance models have unlocked an additional R3.5 billion in private sector investment for projects that would otherwise struggle to attract commercial funding due to perceived risks or extended payback periods.
-
Community Development
Through our community benefit structures, we've directed over R350 million to local development initiatives, including 45 schools, 28 healthcare facilities, and 120 small business development programs. Our flagship Community Energy Ownership model has enabled 17 communities to take equity stakes in renewable energy projects on their land.
What Our Partners Say
Green Investment SA's approach to renewable energy financing has been transformative for our rural electrification initiatives. Their team didn't just provide capital; they brought technical expertise, community engagement strategies, and innovative ownership models that ensured our solar mini-grid projects delivered lasting benefits to communities while generating sustainable returns.
As a development finance institution, we value partners who understand both financial and impact objectives. Green Investment SA has consistently demonstrated this dual capability, creating investment structures that have unlocked private capital for climate adaptation projects that would otherwise struggle to secure funding. Their approach is exactly what South Africa needs to finance its just transition.
Working with Green Investment SA to develop our sustainable agriculture fund has been a game-changer for small-scale farmers in KwaZulu-Natal. Their deep understanding of both agricultural economics and climate resilience helped us design financing models that support farmers through the transition to water-efficient techniques while ensuring long-term productivity and profitability.
