In February 2006, Cape Town experienced its worst power failure ever. The city had lost 75% of its power due to a failure on the grid. The city had to immediately remove 400 MW of unnecessary power usage from the grid. PEER, working as an ESCO, was hired by Eskom to field a team of workers to reduce the residential load to the grid in the downtown area. Mobilizing a team of over 300, including historically excluded youth workers, PEER initiated a residential weatherization and retrofitting (demand-side management) program that consisted of two elements – a swapping program and an installation program.
