Airnergize Capital, the clean technology investment platform of South Africa’s New GX Capital, has confirmed the final close of its debut fund at R3.89 billion, roughly $239 million, with the Development Bank of Southern Africa committing R240 million as lead development finance institution.
The fund brings together some of South Africa’s largest commercial balance sheets alongside state development capital, positioning it to invest at scale across energy, water and gas infrastructure in Southern Africa and beyond.
Inside the Airnergize Capital Fund Close South Africa
The Airnergize Capital fund close South Africa investors assembled reads like a cross-section of the country’s major financial institutions.
Fund I’s investor group comprises New GX Capital, RMB Ventures, Standard Bank, Nedbank and the DBSA, placing South Africa’s major commercial balance sheets and its principal development finance institution inside a single vehicle.
New GX Capital Group Chief Executive Khudusela Pitje described the milestone in terms that emphasized market validation as much as the capital itself, saying reaching R3.89 billion with this calibre of investor around the table tells you the market believes in what the platform is building, and that each investor, including the DBSA, added something different, whether balance sheet strength, sector expertise or a development mandate.
Worth noting is that the final figure landed just under the fund’s originally stated R4 billion target when it first launched, a modest but real gap between ambition and outcome even as the raise itself remains substantial by regional standards.
The DBSA Clean Technology Fund 2026 Rationale
The DBSA clean technology fund 2026 commitment followed a full institutional due diligence process examining Airnergize’s governance framework, risk management and investment protocols before the development bank agreed to anchor the round.
Mahlatsi Molokomme, principal investment officer at the DBSA, explained the logic behind backing a platform rather than individual transactions, saying the DBSA’s mandate is to mobilise capital toward infrastructure that supports inclusive growth, and that a platform like Airnergize does that at scale rather than one deal at a time.
Molokomme added that backing a fund alongside commercial investors allows the DBSA to crowd in private capital rather than compete with it, describing that blended approach as exactly what South Africa needs if it is going to close its infrastructure investment gap.
That framing matters because it positions the DBSA’s relatively modest R240 million contribution as catalytic capital meant to unlock much larger pools of commercial investment, rather than as the primary source of funding for the platform itself.
What New GX Capital Infrastructure Fund Actually Invests In
The New GX Capital infrastructure fund structure is built around thematic investment across renewable energy, gas and water, targeting both capital-heavy and asset-light business models and partnering with experienced management teams running established businesses with proven track records.
Airnergize Capital’s initial deployment phase is focused specifically on commercial and industrial solar photovoltaic projects and battery energy storage assets operating across South Africa, other sub-Saharan African markets and Indian Ocean islands.
The fund was already operational ahead of this final close through the vending in of Sustainable Power Solutions Africa, a New GX portfolio company and a leading integrated commercial and industrial renewable energy owner and operator, giving Airnergize an existing revenue generating asset base to build from rather than starting entirely from scratch.
As a black-owned and controlled platform, Airnergize also positions its investment strategy around measurable environmental and social outcomes alongside commercial returns, aligning its stated approach with the kind of impact oriented mandates that many of its development finance backers require.

Why a South Africa Clean Energy Water Fund Matters Right Now
A South Africa clean energy water fund of this scale arrives at a moment when the country’s infrastructure gaps span multiple, interconnected sectors simultaneously.
South Africa has spent years grappling with electricity supply constraints that have driven rapid growth in commercial and industrial solar and battery storage as businesses seek reliable power outside the constrained national grid.
Water infrastructure carries its own distinct set of challenges around ageing systems, distribution losses and inconsistent access, particularly outside major urban centres.
By structuring Airnergize around energy, water and gas together rather than a single sector, New GX Capital is betting that many of the underlying investment mechanics, project finance structures, long term infrastructure contracts, and the need for patient, blended capital, are similar enough across these categories to be managed within one platform, even though the specific technologies and operating businesses look quite different from one another.
Part of a Broader Platform Strategy
Airnergize Capital does not operate in isolation within New GX Capital’s broader business.
The platform sits alongside AiZAR Capital, the group’s digital infrastructure platform, and Airnergize Ventures, its early-stage clean technology and digital venture arm, giving New GX Capital a structure that spans early stage venture investing, growth stage infrastructure investment through Airnergize, and digital infrastructure through AiZAR.
That layered structure allows the group to back companies at different stages of maturity across adjacent infrastructure themes, potentially routing a company from an early Airnergize Ventures investment through to larger scale project finance under Airnergize Capital as it matures.
What Comes Next
With its final close confirmed, Airnergize Capital’s next test will be translating R3.89 billion in committed capital into operating infrastructure across the energy, water and gas projects it has targeted.
Pitje described the ambition directly, saying the platform has been built to turn this capital into operating infrastructure that moves the needle across energy, water and gas, and that contributes to energy security in South Africa and the region.
Whether that ambition holds up will depend on execution, deployment pace and the underlying performance of the commercial and industrial solar, storage and water assets the fund backs, factors that will only become clear as Airnergize moves from fundraising into active investment across its target markets.
