Years of blackouts taught South African businesses a lesson they have not unlearned: do not wait for the grid. Maia Capital Partners has committed R150 million ($9.12 million) in mezzanine debt financing to Nesa Power, announced July 4, giving the renewable energy company growth capital to expand its commercial and industrial solar business and grow its book of long-term power purchase agreements.
The model: power without the capex
Nesa develops integrated solar, battery storage and energy solutions for commercial and industrial customers under long-term PPAs, which means a factory or retailer gets renewable electricity without the large upfront investment of building its own plant. The new facility funds the acquisition of additional solar photovoltaic sites and accelerates project rollout. It is not a newcomer’s pitch: the company and its founders have built more than 46 megawatts-peak of solar generation and 6.5 megawatt-hours of battery storage, and raised over R400 million through managed investment funds that own and operate more than 70 commercial and industrial solar assets.
A market load-shedding built
The investment reads the market correctly. Years of electricity shortages pushed South African companies to secure independent power, creating one of Africa’s fastest-growing commercial solar markets, and industry forecasts put the country’s private renewable energy market above R200 billion ($12.17 billion) by 2030. “Providing clean, affordable energy to South African businesses is one of our key impact and investment objectives,” said Maia Capital chief executive Tshandu Ramusetheli, tying the deal to the country’s push for private-sector generation. Nesa co-founder and chief executive Mike Bleyenheuft called the facility the capital for the company’s next growth phase as commercial and industrial demand keeps rising.
Why mezzanine debt is the tell
The instrument says something about where this market has matured. Mezzanine debt, sitting between senior loans and equity, is growth capital for companies with proven cash flows, not speculative bets, and its arrival in commercial solar means lenders now trust PPA revenue streams enough to leverage them. Nesa’s decade of operations, spanning project development, engineering and construction management, PPA financing, operations and maintenance, and even carbon credit development including one of South Africa’s first solar-based grouped VERRA projects, is exactly the kind of full-stack track record that unlocks such financing.
The wider current
South Africa’s energy transition is increasingly being financed one rooftop and one factory at a time, with private credit stepping in where grid investment lags. For clean-energy builders across the continent, Nesa’s path is the instructive one: own the whole chain from development to maintenance, sell reliability rather than ideology, and let long-term contracts turn sunshine into a bankable asset. As demand for dependable power keeps outrunning grid capacity, the companies that can finance, build and operate that alternative are compounding, and capital has clearly noticed.
