ERC Guidelines and Instructions

ERC Guidelines for the Application and Approval of Caps on the Recoverable Rate of Distribution System Losses : 

ERC Guidelines for the Application and Approval of Caps on the Recoverable Rate of Distribution System Losses System Planning and Evaluation Division (SPED)

Scope : 

Scope This Guidelines shall apply to the following: Privately-owned DUs LGU owned-and-operated DUs Entities duly authorized to own, operate and maintain distribution facilities within the economic zones; and Other duly authorized entities engaged in the Distribution of Electricity. Electric Cooperatives

System Loss Caps : 

System Loss Caps Consistent with the PDC, the ERC shall specify three (3) system loss caps, namely: A cap on the Technical Loss; A cap on the Non-Technical Loss; and A cap on the Administrative Loss.
