New GX Capital, co-founded by Dark Fibre Africa (DFA) pioneer Khudusela Pitje, and RMB Ventures (RMBV) have launched Airnergize Capital Fund I, a R2.4 billion ($120 million) clean tech investment vehicle targeting renewable energy, gas and water infrastructure across Southern Africa.
“Our journey into the utility industry started six years ago, and we are committed to investing in solutions that will drive sustainable change across Africa,” said Khudusela Pitje, Founder & CEO of New GX Capital.
“Access to clean energy, water, and gas is fundamental to economic growth and social upliftment.”
The fund aims for a final close of R4 billion ($200 million) as it scales sustainable solutions for Africa’s energy transition.
Driving Africa’s Clean Energy Transition
Airnergize Capital, managed by New GX, will invest in high-impact, scalable clean tech businesses, supporting South Africa’s shift toward a low-carbon economy.
Tebatso Modiba, Deal Executive at Airnergize Capital, said: “RMB Ventures shares our vision to build a leading clean tech platform under the New GX umbrella, unlocking a sustainable tomorrow in both South Africa and across the continent.”
The fund prioritises asset-heavy and asset-light models, partnering with proven management teams to accelerate energy access, water security, and gas infrastructure.
As a black-owned and controlled fund, Airnergize combines strategic capital with a focus on measurable ESG impact. Its first investment is already underway through Sustainable Power Solutions Africa (SPS), a leading commercial & industrial (C&I) solar PV and battery storage developer.
“We are excited by the latest development at New GX that will unlock additional capital towards the drive to building SPS into a Pan Africa renewable energy giant,” said Paul Mansour, CEO of SPS.
“SPS BEE credentials with support of New GX are admirable amongst its peers.”
Why This Matters
With load-shedding and water scarcity pressing challenges, Airnergize Capital’s investments will:
- Boost renewable energy adoption (solar, battery storage)
- Expand clean gas infrastructure
- Improve water access and innovation
- Support black economic empowerment (BEE) in clean tech
The fund aligns with global sustainability goals, positioning South Africa as a leader in climate-resilient infrastructure.
: “Combining our private equity expertise with New GX’s renewable energy track record will be instrumental in driving Airnergize’s success,” said Eutychus Mbuthia, RMB Ventures.
“This fund is a crucial step in addressing South Africa’s energy and water challenges.”
