CSP towers’ impact on birdlife lower than expected, can be reduced

A study conducted by Stellenbosch University’s Faculty of AgriSciences has found that the 50 MW Khi Solar One facility, near Upington, is impacting on the surrounding bird life, but not to the extent expected.

It is also possible to reduce the impact that concentrating solar power (CSP) towers might have on bird populations by managing the infrastructure well, especially during downtime when it is not generating power, says the faculty’s HP van Heerden, after completing research at South Africa’s only CSP tower.
