As the sun beat down on the bustling Sandton Convention Centre, the mood at the South Africa Investment Conference 2026 was one of cautious optimism. But for the country’s beleaguered energy sector, a single announcement on the main stage signaled a powerful shift from promise to tangible momentum. Mulilo, a leading South African renewable energy developer, unveiled a massive R15 billion investment package aimed squarely at the nation’s most pressing vulnerability: the stability of its national grid.
The commitment, one of the largest from a pure-play renewable energy independent power producer (IPP) at this year’s conference, is designed to fast-track three large-scale solar photovoltaic (PV) projects and a utility-scale battery energy storage system (BESS). Together, these assets will add a critical 716 megawatts (MW) of new export capacity to the national grid—a contribution designed not just to add megawatts, but to provide the reliable, dispatchable power needed to ease the load-shedding that has hobbled the economy for years.
For Seithati Bolipombo, Chief Commercial Officer at Mulilo, the announcement was more than a press release; it was a statement of intent. Taking the stage after a morning of discussions on public-private partnerships, Bolipombo framed the investment as a definitive vote of confidence in South Africa’s economic trajectory under the Government of National Unity.
“This commitment reflects our conviction that South Africa is on a positive path towards a just energy transition supported by private sector investment in renewable energy,” Bolipombo said to a room filled with investors, government officials, and industry peers. “We are not only investing capital — we are investing in long-term partnerships that unlock infrastructure, create jobs, and deliver tangible impact. We see this not just as a project pipeline, but as the bedrock of a revitalized energy ecosystem.”
The R15 billion pledge is the anchor of a far more ambitious expansion strategy. Mulilo revealed that it is actively progressing a project pipeline aimed at reaching a deployment rate of one gigawatt (1 GW) per year. This target positions the company as a potential cornerstone of the government’s long-term energy roadmap, signaling an ability to deploy significantly more capital in the near term as regulatory frameworks stabilize.
With a development pipeline now exceeding an astounding 30 GW across wind, solar, and battery storage, Mulilo is positioning itself as a key architect of the post-load-shedding era. However, industry analysts note that moving from a 30 GW pipeline to a consistent 1 GW-per-year delivery requires more than just capital.
“The private sector has the appetite and the balance sheets,” said energy analyst Lungile Mashele, who was in attendance at the conference. “What Mulilo is signaling here is that they are ready to move at scale. But the bottleneck is no longer just funding. It’s grid connection queues, municipal approvals, and the speed of Eskom’s own transmission expansion. The success of this R15 billion—and the 1 GW-per-year goal—hinges on the government meeting them halfway on infrastructure readiness.”
The timing of the announcement is critical. Eskom, the state-owned utility, has recently shown improvements in generation performance, but grid capacity in key provinces like the Northern Cape and Western Cape remains constrained. Mulilo’s new projects, strategically paired with battery storage, aim to bypass one of renewable energy’s traditional weaknesses—intermittency. By coupling solar PV with BESS, the company is promising power that can be dispatched during evening peaks, directly targeting the hours when load-shedding has historically been most severe.
Bolipombo emphasized that the R15 billion was just the beginning. She called for a continued, streamlined collaboration between government, regulators, and industry to convert financial commitments into completed infrastructure.
“We have the projects, we have the funding, and we have the teams ready to build,” Bolipombo said in a subsequent media briefing. “But to truly unlock the 30 GW potential in our pipeline, we need a regulatory environment that moves as fast as the technology and the capital does. We are calling for a ‘war room’ mentality—where the private sector is treated as a partner in infrastructure delivery, not just a financier.”
The announcement was met with a positive response from the Department of Mineral Resources and Energy (DMRE), with a senior official noting that private investment of this magnitude reduces the burden on the fiscus while accelerating the Just Energy Transition (JET). As the conference concluded its first day, Mulilo’s pledge stood out as a concrete example of the shift the Investment Conference was designed to foster: moving beyond pledges to power, and from policy to pylons.
For millions of South Africans still reeling from years of power cuts, the news offers a distant but tangible promise—a future where the lights stay on, powered by the sun, backed by batteries, and bankrolled by a private sector betting big on the country’s recovery.
