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, a move that will have direct implications for small-scale self-generation (AGPE) and distributed generation (DG) projects.
The initiative represents the most far-reaching revision of the Electricity Metering Code since its introduction in 2014, reflecting 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 proposing new criteria for the registration, validation and settlement of electricity measurements.
The consultation period remains 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 elements play a critical role in wholesale market settlements, data reliability and the legal certainty of power purchase agreements (PPAs) and other contracts.
"This review is carried out in compliance with Article 1 of **Ministerio de Minas y Energía Resolution 40024 of 2025, CREG stated in the published circular.
While technical in nature, the reform is considered structural for market confidence.
The Metering Code effectively acts as the regulatory "clock" of the electricity system, defining how, when and under what conditions electricity flows are measured, recorded and settled.
In a system increasingly shaped by distributed solar, behind-the-meter generation and prosumers, updating these rules had become a long-standing necessity.
Sector sources, speaking off the record, emphasized the importance of stakeholder participation: "We encourage all interested parties to submit inputs that help strengthen and modernize the regulatory framework.
The revision of the Metering Code is not an isolated measure.
In parallel, CREG has advanced Firm Energy Obligation (OEF) auctions for the 2029 2030 period, enabled new incentives for renewable generation and is expected to launch a long-term clean energy auction in the coming months.
In addition, the Indicative Regulatory Agenda 2025 outlines further reforms, including:
-
Updates to the wholesale electricity market design
-
A review of generation remuneration mechanisms
-
The definition of a national Advanced Metering Infrastructure (AMI) framework
Within this broader roadmap, the Metering Code revision plays a foundational role.
"The update of the Metering Code is a regulatory signal aligned with the transformation of Colombia"s electricity system," said a source close to the process.
Toward a modern and scalable frameworkIf approved, the new regulation would replace CREG Resolution 038 of 2014, which currently defines the technical requirements for electricity metering in the public service.
However, technological evolution and the growing share of distributed generation now require more robust, scalable and precise standards.
Once implemented, the updated framework will help ensure that every kilowatt-hour generated, injected or consumed is measured under verifiable, traceable and reliable conditions a critical foundation for orderly system growth, investor confidence and the continued expansion of renewable energy in Colombia.
