What changed
Río Negro adheres 'in all its terms and conditions' to the Medium-Sized Investment Incentive Regime (RIMI) created by Title XXIII of national Law 27,802 and implemented by Decree 242/2026 (art. 1). Art. 2 creates a simplified procedure: the certificate of adhesion to the national RIMI operates as an exempting instrument for the documentation required by Law 5766 (Río Negro's Economic and Industrial Promotion Regime) — the national beneficiary enters the provincial regime without duplicating paperwork. Art. 3 clarifies that the simplification does not waive substantive compliance with Law 5766. Enforcement authority: Ministry of Economic and Productive Development; for developers of industrial or logistics parks, the Industrial Parks unit of the Secretariat of Energy and Environment (art. 4). Implementing rules within 90 days (art. 5); effective upon publication (art. 6). Passed unanimously on Jun 11, 2026; promulgated by Decree 597/26 (Weretilneck) on Jun 12, 2026. verif · Jun 16, 2026 ↗

Our reading
Río Negro plugs into the RIMI without friction: a single national certificate also opens the provincial promotion regime. For the satellite SME of the energy corridor and the Alto Valle, the combo lowers the cost of re-equipping just as boom demand requires it — province-Nation alignment on the investment agenda (R5 · better export netback). thesis
