The Portuguese government has acquired a 13.7% stake in the National Energy Network (Redes Energéticas Nacionais or REN) for 380 million euros. While the government cites national sovereignty and energy security as reasons for the move, critics argue the acquisition signals a return to state capitalism and lacks a clear economic rationale, given that the sector is already strictly regulated.

Context & Explainers

REN (Rede Eléctrica Nacional) is Portugal's operator for high-voltage electricity transmission and for gas transport infrastructure, responsible for running the transmission grid and keeping the system stable. It also publishes national electricity consumption data and is the main contact in cases of large-scale outages or transmission issues.
