What changed and who it applies to
What changed
Concession holders, permit holders and parties authorized for the exploration, production, transport, storage and processing of energy or mineral resources in the Province —and their contractors and subcontractors— must guarantee that a minimum of 60% of the contracting of goods, services and works, across the different stages and under any direct or indirect arrangement, is executed by Rio Negro suppliers (art. 6). They must also INVITE THE SUPPLIERS REGISTERED on the digital platform TO BID and PUBLISH ON IT every contracting requirement (arts. 6.2 and 13). The Rio Negro supplier has the RIGHT TO MATCH the best offer and take the award if its bid meets the quality, safety and operational requirements of the tender and its price does not exceed the best one by more than 8% (art. 7); in the event of a tie, preference goes to the registered supplier, then to the one with an operating establishment in the Province, and then to the one employing more workers with accredited residency (art. 8). It creates the Rio Negro Supplier Registry under the Secretariat of State for Energy and Environment (art. 14), with free registration valid for 12 months and renewable (art. 16). Art. 4.2 expressly admits companies linked to or controlled by national or foreign groups if they prove local establishment and local value added (jobs, investment, technology). Art. 5 refers to law J 2904: the same obligated parties must additionally comply with the local-labor regime. verif Aug 21, 2025 ↗
In force
The law has been in force since September 2025 and the regime became fully operational with its implementing rules: Decreto 618/26, issued on 22-06-2026, approves the regulation of Ley 5805 and its annexes, and was published in Boletín Oficial 6504 of 29-06-2026. verif Jun 22, 2026 ↗
Are you in or out?
For the obligated parties (VMOS, SESA, operators, EPC contractors and their subcontracting chains) it sets a local-procurement floor of 60%; for Rio Negro SMEs it does not guarantee the sale: it guarantees the invitation — art. 7 gives them the right to MATCH the best offer only if their price does not exceed it by more than 8%, and above that window the award goes to the outside bidder. With the art. 4.2 door open for outside groups to 'become local' by establishing themselves. Mandatory publication of contracting requests on an official platform (art. 13). verif 2025-2026 ↗

Our reading
Together with the 80/20 labor rule, this is Rio Negro's rent capture on the corridor: the toll is not a tax, it is mandatory participation of local supply. For the satellite supplier the reading is twofold: getting certified in the Registry means entering the reserved 60%; and art. 4.2 is the legal door for an outside company to establish itself and compete from inside - the real bar will be how the implementing rules measure 'local value added'. ⚠️ And that door is an ASYMMETRY with Neuquen, not a Rio Negro detail: there, Ley 3338 excludes in its art. 11 anyone linked to or controlled by a national or foreign group that does not meet the requirements, and Ley 2683 does the same in its art. 5 for public procurement. ⇒ the very company Rio Negro admits if it establishes itself is the one Neuquen leaves out, and that decides how to structure the company BEFORE investing: in Rio Negro it is enough to establish yourself and show local value added; in Neuquen you have to look at who controls the parent. Both Neuquen records already said so from their side; this one says it from its own. Market signal already visible: the Registry went from ~374 to ~476 registered companies upon regulation (308 effectively certified as of Mar-2026, per press reports prob). ⚠️ We opened the art. 13 platform on August 30, 2026 and it does NOT publish contracting requirements. Both official surfaces of the Registry —the Economic Development Agency's and the Río Negro government's own— are registration only: a form to sign up, with no public list of registrants, no tenders and no requests for bids. The procurement portals they link to belong to the province's own public purchasing, not to the parties bound by the law. ⇒ the duty to publish «every contracting requirement» (arts. 6.2 and 13) is today met on no public surface, and without it the art. 7 right to match has no trigger: you cannot match an offer you cannot see. What this changes for the supplier: registering is still necessary —it is what puts you inside the reserved 60%— but it is not enough to find out about a contract. Today the real route is to go to the contractor, not to wait for the invitation; and that platform going live is a signal worth watching, because the day it publishes, the sales channel for the whole corridor changes. thesis
