The Independent Power Producer Office (IPPO) has confirmed that the deadline for submissions under Bid Window Seven (BW7) of the Renewable Energy Independent Power Producer Procurement Programme has been extended by a month to May 30 to accommodate both grid-connection quotes and a curtailment addendum published by Eskom. The IPPO told Engineering News that a briefing note extending the timeline for application for grid cost estimate letters (CELs) to February 15 was issued at the end of January following requests from potential bidders at a bidders’ conference that took place on January 17.
