Iconic South African Town in the Middle of Nowhere Has Two Rare Solar Power Plants

Why It Matters

The dual CSP installations demonstrate the viability of large‑scale solar thermal generation in arid markets, diversifying South Africa’s energy mix and reducing reliance on coal. Their long‑term PPAs and job creation illustrate how renewable projects can drive regional development.

Key Takeaways

• Pofadder hosts South Africa's only two CSP plants.
• KaXu, first with thermal storage, 100 MW capacity.
• Xina adds another 100 MW, operational since 2017.
• Plants supply ~320 GWh annually, powering 80k homes.
• CSPs create ~120 permanent jobs, boost local economy.

Pulse Analysis

The Northern Cape’s stark, sun‑bathed terrain has long been a testing ground for South Africa’s renewable ambitions. While wind farms dot the coastal belt, concentrated solar power (CSP) offers a different advantage: the ability to store thermal energy and dispatch electricity after sunset. In a country where coal still dominates the grid, CSP plants provide a dispatchable, low‑carbon alternative that aligns with the nation’s Integrated Resource Plan. Pofadder’s isolation, once a liability, now serves as an ideal site for high‑insolation projects that require vast, flat land and minimal grid congestion.

KaXu Solar One, commissioned in March 2015, became the continent’s first CSP with molten‑salt thermal storage, delivering 100 MW of baseload power for up to 5.5 hours without sunlight. Its sister facility, Xina Solar One, reached commercial operation in 2017, mirroring KaXu’s capacity and technology. Combined, the two plants produce roughly 320 GWh annually—enough to power about 80,000 South African homes—and are secured by 20‑year power‑purchase agreements with Eskom. The projects created several thousand construction jobs and now sustain a stable workforce of 120‑130 technicians, engineers, and support staff.

The success of the Pofadder CSP complex signals a broader shift toward utility‑scale solar thermal in emerging markets with abundant sunshine and water constraints. By demonstrating reliable, dispatchable power, KaXu and Xina reduce the intermittency concerns that have limited solar uptake, encouraging further private investment and potential replication in other arid regions of Africa. Moreover, the long‑term PPAs provide revenue certainty for financiers, while the permanent jobs inject much‑needed income into a remote community. As South Africa pursues its net‑zero targets, CSP could become a cornerstone of a diversified, low‑carbon grid.
