Portugal’s Minister of Environment, Maria da Graça Carvalho, has urged the country’s energy regulator, ERSE, to increase transparency in the fuel market and actively regulate gas stations. Carvalho sent a letter to ERSE requesting greater oversight and demanding the regulator have the authority to enforce compliance. ERSE responded by emphasizing the need for public access to information regarding fuel price formation. Crucially, the entity is requesting legal powers to sanction businesses that violate existing regulations within the sector. This push for greater control comes amidst ongoing public concern over fuel costs and potential market manipulation. The aim is to ensure a fairer and more transparent system for consumers, with penalties serving as a deterrent against unlawful practices. The move signals a potential shift towards stricter market regulation in Portugal’s fuel industry.
