Rules on Meter Type Approval for Utilities

The Rules Governing the Type Approval of Meter Products aim to protect the public interest by ensuring the accuracy and proper functioning of watt-hour meters.
These rules apply to meters used by Distribution Utilities (DUs) and Redistributors in revenue metering.
They require compliance with standards adopted by the ERC for meters under normal working conditions.

The Rules provide for the creation of a common database of acceptable watt-hour meter types.
This database serves as a reference for DUs and Redistributors when procuring meters for consumers.

The draft Rules were posted on the ERC website and published in newspapers to ensure transparency.
Expository presentations and public consultations were held to solicit feedback from stakeholders.
Comments received were incorporated into the revised draft, which was also posted online.

The ERC officially approved and adopted the Rules after deliberation.
The Rules supersede any previous ERC issuances inconsistent with the current provisions.
The Resolution and the Rules take effect 15 days after publication in a newspaper of general circulation.

Copies of the Resolution were distributed to the University of the Philippines Law Center (UPLC-ONAR) and all relevant electricity metering entities.
This ensures that all stakeholders are informed of the new regulatory requirements.
