ABIDJAN, May 14 (Reuters) - Ivory Coast cocoa grinding could drop by 40% to 25,000 tonnes in May, and even further in June, due to power shortages in the world's top grower, five sources, including some in the exporters' association GEPEX said on Friday.

Grinders will be allowed to export and process their beans elsewhere, likely in their European or U.S. factories, due to the power crisis, said industry regulator, the Coffee and Cocoa Council (CCC). (Reporting By Ange Aboa Writing by Nellie Peyton Editing by Edward McAllister)
