Colombia Updates Electricity Metering Code for Distributed Generation

The energy regulator has launched a public consultation to overhaul the Electricity Metering Code, redefining technical standards for measuring injected and consumed power as distributed generation gains scale.

Colombia’s energy regulator, Comisión de Regulación de Energía y Gas (CREG), has opened a public consultation process to comprehensively update the country’s electricity metering framework.this will directly impact small-scale self-generation (AGPE) and distributed generation (DG) projects.

this initiative is the moast far-reaching revision of the Electricity Metering Code since its introduction in 2014. it reflects the rapid growth of distributed energy resources, solar PV systems, and self-consumption schemes across the Colombian power system.

Through Circular 220 of 2025, published on December 22, CREG invited all market participants-including utilities, system operators, industry associations, and end users-to submit comments on a technical Analysis Document. This document proposes new criteria for the registration, validation, and settlement of electricity measurements. The consultation period is open until December 27.

The proposed update addresses sensitive and highly technical issues such as equipment calibration, metrological traceability, routine testing procedures, and operational conditions of metering systems. These
