The 22MW Herbert and the 11MW Greefspan plants, located near Douglas in the Northern Cape Province, were constructed by US-based SunPower and were part of the South African government's Independent Power Producers Procurement Programme.

Both systems are owned by AE-AMD Renewable Energy, a joint venture between Spain's AMDA energía and South Africa's Alt-E Technologies, and its partners.

Electricity generated from the projects will be sold to state utility Eskom.
