Nelson Thabo Modupe, of Lichtenburg, has argued that he prevented power cuts during the 2010 Soccer World Cup through his prayers.
He is a member of the Zion Christian Church.
In a letter to Eskom, he said the main reason for load shedding was lightning and wind, and that he had taken it upon himself to pray to God and ask that no power cuts take place.
As a result, Eskom now owes him R250m, because he saved the power utility the burden and humiliation of load shedding.
Alternatively, Eskom can offer him a partnership in the company.
The claim has been placed on the court roll in the North West High Court for Thursday.
