Solar Power Shines Bright: Doubling Down on Clean Energy with SPS

January 27, 2026

EXSA is committed to driving power to pioneer progress.

We are thrilled to announce a significant expansion with our partner, Sustainable Power Solutions (SPS), on the SlimSun Too Solar IPP. This landmark partnership is set to deliver clean, affordable energy directly into South Africa’s grid , setting a powerful example of how private sector collaboration is accelerating the country’s energy transition.

The Project: Scaling up Capacity and confidence

This partnership is all about scaling up the sustainable power available to our clients. The initial phase of the SlimSun Too Solar IPP is a substantial 5,600 kWp solar farm , a project valued at R87 million with financial backing from Investec. EXSA has secured the power through a 10-year Power Purchase Agreement (PPA) with SPS, who serves as both the IPP and EPC contractor.

The real story, however, is the confidence we have in this model:

  • Capacity Doubled: We’ve already reached financial close on a contract to double SlimSun Too’s capacity to 10 MW. This immediate expansion shows our long-term commitment and strengthens our portfolio for you, our customer.
  • Momentum Secured: Construction on the expansion phase is scheduled to commence in the coming months. This capacity growth contributes to long-term energy security by increasing national generation capacity.

 

Milestones, delivery and mandate

This is a project that is already delivering. Phase 1 is in the final commissioning stage, following approval of the Eskom grid connection. With RETEC testing in progress, the plant will soon begin supplying renewable power directly through EXSA, marking a major step in improving access to affordable, sustainable power for South African businesses.

Our commitment here is clear. As EXSA CEO, Wayne Cowie, noted, “This project showcases our dedication to advancing South Africa’s Just Energy Transition. By partnering with SPS, we’re not only expanding our renewable energy capacity but also contributing to the country’s economic growth and sustainable development”.
