The Portuguese Communist Party (PCP) has voiced skepticism regarding the state’s recent acquisition of a 13.7% stake in REN, the national electricity grid operator. The PCP argues this purchase doesn’t automatically translate into increased public influence over the energy sector. They question whether the move effectively strengthens public control or merely represents state capital investment. The party believes deeper structural changes are needed to guarantee greater public oversight. This acquisition signifies a return of state capital to REN after previous privatization efforts. The PCP's position emphasizes the need for policy changes alongside shareholding to achieve meaningful influence within the energy market. They suggest the purchase alone isn’t a sufficient solution to address concerns about public control.
