Colombia Orders Gas Companies to Reimburse Consumers Over $150 Million in Overcharged Fees
Bogotá, Colombia – The Colombian government has ordered gas companies to return more than 150 billion pesos (approximately $37.5 million USD as of March 4, 2026) to consumers after determining that an improperly applied increase in the cost of capital discount rate – known as the WACC – led to inflated bills. The decision, announced by the Ministry of Mines and Energy and mandated by the Commission for the Regulation of Energy and Gas (CREG), impacts households and businesses across the country and represents a significant win for consumers facing rising energy costs. The move underscores the government’s commitment to ensuring fair pricing practices within the energy sector and comes amid broader discussions about energy affordability and access.
The core of the issue stems from a 2023 resolution (CREG 102 002) that increased the WACC, a key indicator reflecting the profitability of investments in the sector, from 10.94% to 11.88%. This adjustment allowed gas transportation companies, including Transportadora de Gas Internacional (TGI), a subsidiary of Grupo Energía de Bogotá, and Promigas, linked to Grupo Aval, to increase their transportation costs. These increased costs were then passed directly onto consumers, impacting monthly gas bills. The government’s intervention reverses this decision, requiring companies to recalculate charges and reimburse the overcollected funds.
The WACC Adjustment and its Impact
The WACC, or Weighted Average Cost of Capital, is a crucial metric in Colombia’s energy regulation. It represents the average rate of return a company is expected to pay to its investors, factoring in both debt and equity. A higher WACC generally translates to higher costs for consumers, as companies seek to recoup their investment and ensure profitability. According to the Ministry of Mines and Energy, the 2023 increase in the WACC enabled TGI and Promigas to inflate transportation costs, ultimately burdening complete-users.
Following the CREG’s initial decision to raise the WACC, gas distributors filed appeals requesting that the rate be maintained at 10.94% even as new tariff charges were being approved. This was an attempt to mitigate the immediate impact on household and commercial bills. The CREG, led by the Minister of Mines and Energy, ultimately sided with the distributors, ordering the reduction of the WACC and mandating the reimbursement of excess funds collected since 2023. This decision highlights the regulatory body’s responsiveness to concerns about affordability and its willingness to correct course when necessary.
How Will Reimbursements Be Processed?
The CREG is currently defining the specific mechanisms and timelines for the reimbursement process. Companies will be required to reflect the reimbursements directly on consumer bills. The Ministry of Mines and Energy has stated that the process is now entering an operational phase to ensure that the funds are returned to gas consumers throughout the country efficiently and transparently. While specific details regarding the method of reimbursement (e.g., direct credit, bill reductions) are still forthcoming, the government has assured the public that the process will be clearly communicated.
The scale of the reimbursement – exceeding 150 billion pesos – suggests a widespread impact across the Colombian energy market. The affected companies, TGI and Promigas, will be responsible for implementing the CREG’s directives and ensuring compliance with the new regulations. The Ministry of Mines and Energy will oversee the process to guarantee accountability and protect consumer interests.
Broader Context: Energy Policy and Affordability in Colombia
This decision arrives at a time of heightened scrutiny regarding energy costs and affordability in Colombia. The government of President Gustavo Petro has been actively pursuing policies aimed at reducing energy prices and increasing access to affordable energy sources. Notably, Petro recently announced plans to import natural gas from Venezuela, aiming to leverage potentially lower prices. However, the feasibility of this plan hinges on the repair of the Antonio Ricuarte gas pipeline, a project estimated to take up to two years.
The current reimbursement order is separate from, but complementary to, these broader energy policy initiatives. By correcting past pricing errors and ensuring fair tariff structures, the government aims to alleviate the financial burden on consumers and promote a more sustainable and equitable energy system. The move also sends a clear signal to energy companies that regulatory oversight will be rigorous and that consumer protection remains a top priority.
Impact on Key Players
The decision directly impacts TGI, a subsidiary of Grupo Energía de Bogotá, and Promigas, linked to Grupo Aval. These companies will bear the financial responsibility for the reimbursements and will need to adjust their financial projections accordingly. While the reimbursement represents a short-term financial setback, it is unlikely to fundamentally alter the long-term viability of these major players in the Colombian energy sector.
Consumers, stand to benefit directly from the reimbursements, which will provide a welcome financial relief, particularly for low-income households. The move is also likely to bolster public trust in the government’s commitment to protecting consumer interests and ensuring fair energy pricing.
Looking Ahead
The CREG will now focus on finalizing the specific details of the reimbursement process, including the timelines and methods for returning the funds to consumers. The Ministry of Mines and Energy will continue to monitor the implementation of the decision and ensure compliance from the affected companies.
The government is also expected to continue pursuing its broader energy policy objectives, including the exploration of alternative energy sources and the development of infrastructure to improve energy access and affordability. The success of these initiatives will be crucial in shaping the future of Colombia’s energy landscape and ensuring a sustainable and equitable energy system for all.
The next key step will be the CREG’s official announcement of the reimbursement schedule and procedures, which is expected within the coming weeks. Consumers are encouraged to monitor updates from the CREG and their respective gas providers for detailed information on how the reimbursements will be processed.
