Analysis · PAM · Energy & Transportation
The termination of the HINISA concession marks the end of Pampa's operational control over the Los Nihuiles hydroelectric system. While the transition period was previously disclosed, the formal handover of assets to the Province of Mendoza is now complete. This removes a revenue-generating asset from Pampa's portfolio, though the financial impact is not quantified in the filing. Given the company's recent focus on large-scale growth projects like the $2.7 billion fertilizer complex and the $4.5 billion RDA project in Vaca Muerta, the loss of this concession may be strategically manageable but still represents a reduction in its generation capacity.
