Eskom Holdings contracts with five international companies will be scrutinized by South African state investigators as part of a widening probe into graft at the debt-laden State-owned utility. The probe will review agreements with North American engineering services firms WSP Global and Black & Veatch, as well as agreements with Alstom of France, Switzerland’s ABB and Italian firm Teneo, Eskom said. Documents submitted by Eskom to the South African parliament’s Standing Committee on Public Accounts detailed the contacts. The group asked Eskom last month for contract information.
