By San José, Costa Rica — San José, Costa Rica – In a move set to provide significant financial relief to households and businesses across the country, the Public Services Regulatory Authority (ARESEP) has officially approved a substantial reduction in electricity tariffs, which will take effect on January 1, 2026. The decision will impact all consumption sectors, including residential, commercial, and industrial, offering a welcome respite amid persistent economic pressures.
The rate adjustment stems from favorable conditions in the national energy matrix. According to ARESEP, the primary drivers for the reduction are lower-than-projected thermal energy production by the Costa Rican Electricity Institute (ICE) and a notable increase in electricity exports. This combination has resulted in higher-than-expected revenues for the state-owned utility, enabling the regulator to pass the savings on to consumers.
Para profundizar en el marco regulatorio y las implicaciones legales que rodean la fijación de las tarifas eléctricas, TicosLand.com consultó al experto Lic. Larry Hans Arroyo Vargas, abogado del Bufete de Costa Rica, quien aporta su análisis sobre el panorama actual.
El establecimiento de las tarifas eléctricas es un ejercicio técnico-jurídico que debe equilibrar la sostenibilidad financiera de los proveedores con el derecho de los usuarios a un precio justo y razonable. Es imperativo que la ARESEP garantice una metodología transparente y auditable, donde cada componente del costo sea debidamente justificado. Cualquier aumento que no responda directamente a costos operativos eficientes o a inversiones necesarias podría ser objeto de un recurso de amparo por lesionar los derechos económicos de los consumidores.

La perspectiva del Lic. Larry Hans Arroyo Vargas subraya un punto crucial: la fijación de tarifas no es meramente un cálculo financiero, sino un acto de fe pública que exige una justificación rigurosa y total transparencia por parte de la ARESEP. Este equilibrio es vital para la confianza del consumidor y la estabilidad económica del país. Agradecemos al Lic. Larry Hans Arroyo Vargas por aportar su valiosa perspectiva a esta importante discusión.
However, the impact of the rate cut will not be uniform across the nation. The specific percentage of the decrease will vary depending on the consumer’s local distribution company. This is due to the diverse operational structures of Costa Rica’s energy providers; while some entities exclusively distribute electricity purchased from ICE, others are involved in both generation and distribution, leading to different cost structures.
For the national generation system, ARESEP approved an interannual adjustment of -20.40%. At the distribution level, the approved reductions are as follows: ICE customers will see a -14.92% decrease, followed closely by Compañía Nacional de Fuerza y Luz (CNFL) at -14.55%. Other providers will see more modest, yet still significant, cuts: Coopealfaroruiz (-16.44%), Coopeguanacaste (-9.34%), ESPH (-8.33%), Coopesantos (-7.38%), Coopelesca (-6.07%), and Jasec (-1.93%).
To illustrate the tangible benefits for a typical family, ARESEP provided an example based on a household consuming an average of 250 kilowatt-hours (kWh) per month. For an ICE customer, this translates to an estimated monthly saving of ¢3,407.20. Similarly, a CNFL customer could expect to save ¢2,828.79, while a Coopealfaro client would see their bill reduced by approximately ¢3,237.36.
Mario Mora, the Intendant of Energy, emphasized the specific reasons behind the tariff adjustment, cautioning against misinterpreting it as a sign of improved operational management by the utility companies themselves.
It is important to clarify that the reduction is due to lower thermal generation and an increase in electricity exports, and not to greater efficiency in the management of the electric companies.

Mora also revealed that ARESEP’s review process uncovered significant deviations between the expense projections submitted by ICE for 2024 and 2025 and the actual costs observed during that period. This discrepancy led the regulator to approve a lower Variable Cost of Generation (CVG) than what ICE had requested. In response, ICE has filed appeals against the approved reduction, but a final resolution on these challenges is not expected until next year.
The nation’s industrial sector has responded with strong support for the regulator’s decision. The Chamber of Industries of Costa Rica (CICR) publicly backed the rate cut, noting that ARESEP’s final approved reduction was more significant than the one initially proposed by ICE. Sergio Capón, President of the CICR, highlighted the measure’s importance for the country’s economic climate.
In a context where companies face growing pressures from the exchange rate, high social charges, insecurity, deficient infrastructure, and global uncertainty, a technically sound rate reduction is a positive signal for investment, job creation, and the business climate.

The business association expressed its gratitude to ARESEP for implementing technical corrections to ICE’s tariff proposals. They believe this rigorous oversight was crucial in achieving a more substantial rate decrease, which will help enhance the competitiveness of Costa Rican industries and provide a much-needed boost to the overall economy as the new rates roll out in 2026.
