The province of Tierra del Fuego is managing a transition in the energy sector following the decision by a consortium (UTE)—comprising Roch S.A., Secra, Crownpoint Energía S.A., and DPG—not to extend oil concessions for the Angostura, Las Violetas, and Río Cullen areas. To prevent production halts and protect the local economy, Roch S.A. will continue operations on behalf of the province until a new concessionaire is selected via public bidding. This transition plan includes the province acquiring fixed assets, such as infrastructure, processing plants, and vehicle fleets, to increase state involvement in resource exploitation. The arrangement also addresses labor concerns, with workers expected to continue duties under Roch S.A. while the UTE remains responsible for end-of-concession indemnities. Simultaneously, the provincial government has issued a formal repudiation regarding the presence of the VS Promise, a British-flagged oil tanker, in the Port of Ushuaia. Officials characterized the vessel’s presence as a “grave contradiction” to national sovereignty policies, particularly regarding the Malvinas, South Georgia, and South Sandwich Islands. The provincial administration has labeled the operation “inadmissible,” noting the contradiction of allowing a UK-flagged ship to dock while the United Kingdom maintains occupation of the islands. This controversy occurs amidst a legal challenge by the province against the national intervention of the port by the National Agency of Ports and Navigation (ANPyN). Local officials argue that while the national government claimed the intervention was necessary to protect sovereignty, its management has permitted operations that conflict with those interests. Local legislators have further demanded transparency, calling for the national government to disclose the political and administrative criteria used to authorize the tanker's entry.
