CREG 2026 Energy Program: Extra Charges for Excess, Incentives for Savings Amid El Niño

Beginning September 1, 2026, residential energy consumers in Colombia face financial penalties for exceeding their monthly baseline electricity use by more than 10%, according to resolutions issued by the Comisión de Regulación de Energía y Gas (CREG). The temporary six-month program aims to conserve energy ahead of a projected severe El Niño event.

The Bottom Line

• The Trigger: Consumers exceeding their 12-month historical consumption average by over 10% face additional surcharges exclusively on excess kilowatt-hours (kWh).
• The Incentive: Households cutting usage by more than 10% earn a potential credit balance, funded directly by collected penalties and redistributed if resources allow.
• The Timeline: The first billing cycle serves a strictly pedagogical and informational role, meaning penalties will not be assessed immediately on September bills, though conservation efforts are recorded.

Decoding the CREG Regulatory Framework

The regulatory shift, formalized via Resolución CREG 101 120 of 2026 and modified by Resolución CREG 101 126 of 2026, tackles mounting stress on Colombia’s hydroelectric grid. International climate models place an 81% probability on El Niño reaching extreme intensity between October and December 2026. This atmospheric shift threatens severe depletion of reservoir inflows just as domestic energy demand hits historic peaks, according to regulatory disclosures.

Here is the math. Each end-user receives a dynamic baseline quota calculated from their average consumption over the preceding twelve months. If a household maintains a 100 kWh baseline but logs 115 kWh on the meter, the 15 kWh overage triggers a penalty calculation on the surplus 5 kWh. Conversely, reducing demand below 90 kWh unlocks potential bill credits at the program’s conclusion.

The CREG confirmed that the pricing structure does not alter underlying base tariffs. Instead, capital extracted from over-consumers feeds a redistribution pool for conservers.

Exemptions, Safeguards, and Exclusions

Hospitals, educational institutions, emergency services, security forces, and individuals reliant on medical equipment connected to the electrical grid are permitted to opt out by notifying commercial energy providers.

Consumers utilizing prepaid meters or those experiencing active service suspensions remain entirely outside the scope of the resolution. Regionally, urban centers and municipalities impacted by the August 10, 2026 earthquake receive blanket exemptions from the conservation mandates.

Overview of CREG Energy Conservation Framework

Consumption Bracket	Regulatory Action	Financial Impact
Exceeding Baseline by >10%	Surcharge on excedentary kWh	Additional fee applied to bill (after pedagogical month)
Meeting Baseline (±10%)	Standard billing applies	No change to baseline rate
Reducing Usage by >10%	Eligible for conservation reward	Potential credit balance funded via penalties

Oversight and Systemic Market Integration

Monitoring the execution of the mandate requires cross-institutional oversight. XM, the operator of the National Interconnected System (SIN), works alongside the Ministry of Mines and Energy and the Superintendencia de Servicios Públicos to track daily grid loads and verify household performance metrics.

“Actuar desde ya es la mejor forma de cuidar nuestras reservas hídricas. Ahorrar no es un castigo, es una invitación a que todos pongamos nuestro grano de energía. Lo que ahorremos hoy nos ayudará a contar con la energía que necesitaremos mañana”, stated CREG Executive Director Adriana María Jiménez.

While the initial September billing period carries zero financial risk for non-compliant consumers due to its educational grace period, cumulative tracking of kilowatts remains active.
