Catriel. The
Allen plant sits minutes from the Neuquén service bases: there, the rule to hire people from Río Negro is what weighs.
thesis the whole entry map → Where you get inDemand is not what is missing: it is created by an asset that is already contracted. What is missing is someone who can serve it, and it has four layers:
the 4 routes → By 2028 the Río Negro energy corridor will have left in place machines that spin and cannot be switched off: a new compressor plant at Allen —60,000 HP according to the act that approved the project— plus the uprating of the existing one at San Antonio Oeste, two compressor stations at the LNG facilities, and the crude-system pumps between Allen and Punta Colorada. A dedicated pipeline feeding a liquefaction plant does not tolerate an unplanned shutdown: when the compressor stops, the gas does not flow and the vessel waits. Today we have not identified anyone doing that maintenance from Río Negro: it is bought in Neuquén, in Bahía Blanca, or from the factory. And the market has one feature that decides the whole strategy: it is contracted by the year, not by the event.
This market does not bill yet, and that is worth saying first: the Allen compressor plant starts spinning when the San Matías pipeline is commissioned, expected in 2028, and the LNG stations on the same stretch follow.See the clocks that are running, one by one
What gets decided before that date is who ends up qualified. And there is one fact that orders the calendar better than any forecast: maintenance on a machine that spins is not bought by the event, it is contracted by the year. In 2024 TGN won a two-year contract to maintain the three turbocompressor units at YPF's Planta Turbo Expander in Loma de la Lata. Whoever arrives after the first contract does not compete: they wait for the renewal.
What the market is made of
The split of this niche is decided by two owners, not by competition. Whoever built the machine controls the spare part and the hot-section procedure; whoever operates it decides whether to build an in-house team or hand the package to a transport company. Between those two ends there is a band of work that needs no factory authorisation, and that is the one that can be contested from Río Negro.
How it splits, and against which totalSplit over the midpoint TAM of ~USD 4.1 M/yr at steady state, from 2028-2029. The wedge captured by a base established in the corridor —~USD 0.4 M/yr within two or three years— is a share of the addressable market, not a third block: that is why it does not add on top.

▸ The binding limit is the calendar: this market does not bill until 2028, so a base established now needs bridging load for two years — the rotating equipment of the construction itself and the mature fields of Catriel and the Valle Medio. The second limit is the calculation: the 2-4 % annual maintenance intensity is a sector standard rather than a Río Negro figure, which is why the band is deliberately wide.
Who really pays?
Three payers, and the order in which to knock is not the order of size:
If you sellMaintenance of the rotating equipment of the pipeline and its compressor plant
→
The construction is done by the Víctor Contreras and SICIM joint venture and the compressor plant is being built by OPS prob; maintenance is contracted by whoever operates the asset, not by whoever builds it thesis. To operate it, the environmental impact study provides for a minimal crew: two dispatch operators per shift, one mechanic and one electrical and instrumentation technician on day shift verif. With that crew, anything beyond routine is bought from outside thesis.
If you sellMaintenance of the compressor stations and the rotating equipment of the LNG facilities
→
Southern Energy, for the part that stays onshore prob ↗ The boundary matters: the floating liquefaction units belong to Golar, which charters them to the consortium for twenty years verif; the contract for the second unit became firm in October 2025 verif. The maintenance of those units happens offshore, so it does not touch Río Negro soil and does not enter this number thesis. What does stay onshore are the interconnection to the trunk pipelines, the two compressor stations and the onshore pipeline to the coast prob.
If you sellMaintenance of the crude-system pumps
→
This is the door that opens first, because VMOS enters operation before the gas does: the connection at Allen is scheduled for 15 December 2026. And it is the one that combines best with the other two: the same vibration and alignment instruments serve an export pump and a turbocompressor, and that is why the niche is viable as a corridor base rather than as the supplier of a single plant thesis.
▸All three doors share the same calendar requirement, and it is the practical advice of the niche: the entry window is not when the asset starts up, it is when the maintenance tender is drafted, which is prepared alongside commissioning and awarded for years. Whoever appears after the first contract does not compete on price: they wait for the renewal.

There is a third-party decision that defines whether this market exists or is born closed, so one thing is watched above all others:
What to watchWhat changes when it happensStatus
How the operator structures the maintenance tender
Two incompatible branches. Split by speciality —diagnostics on one side, overhaul on another, auxiliaries on a third— a Río Negro base can fight for its share from the first contract. Handed turnkey to a transport company, the niche becomes a subcontract of that winner and the margin is split.
undefined, with no tender published as of 14 September 2026. The signal that it is being decided is the tender itself, prepared alongside commissioning
unconf · Sep 14, 2026The crude system's pumps enter service
This is the first door and it arrives almost a year and a half before the gas one: the same vibration and alignment kit works for an export pump and for a turbocompressor, so it sustains the team until gas starts.
the oil pipeline's connection to YPF's facilities at Allen is set for 15 December 2026.
See the evidence
the terminal's full-capacity target was brought forward from 2028 to July-September 2027
The Allen compressor station enters service
This is the niche's large asset —60,000 new HP according to the act, at Allen according to the environmental impact study
verif , plus the uprating of the existing one at San Antonio Oeste— and the one that turns the market recurring. It starts with the pipeline's authorisation.
the act that approved the project estimates the start of operation for 1 May 2028.
See the evidence
Each new contracting stage of the corridor
The 60% Río Negro local-content share is counted per project unit, not once a year, and every requirement is published with a minimum of five business days to bid. ⇒ there is not one chance to get in: there is one per stage.
What signals the game has changed
The market does not exist until 2028 and there is nothing to bill in the meantime
The compressor station enters service with the pipeline's authorisation, expected in 2028, and the LNG stations in the same stretch.
See the evidence
A base established in 2026 does not have THAT customer for two years. But the way out is no longer merely theoretical: the crude system's pumps enter service much earlier —the connection at Allen is scheduled for 15 December 2026 and the terminal's full-capacity target moved to July-September 2027— and they use the same instruments. On top of that come the construction's rotating equipment —air compressors, generators, hydrotest pumps— and the mature fields of Catriel and the Valle Medio, which the conventional workover niche describes separately.
The first contract is signed for years and closes the door behind it
TGN's own case shows it: maintenance of the three units at Loma de la Lata was awarded for two years.
See the evidence
If the operator hands the package to a transport company before a local alternative exists, whoever arrives later waits for the renewal. The entry window is not when the asset starts up: it is when the tender is drafted, which happens alongside commissioning.
Without the manufacturer's authorisation you can diagnose but not repair the part that carries the margin
The original spare part and the hot-section procedure are controlled by whoever built the machine. A shop without that authorisation stays on the cheap side of the work. Obtaining it takes time, requires a trained crew and a test bench, and cannot be bought: it is earned.
The crew is the bottleneck, and it is in another province
A turbomachinery technician is trained on a fleet, and Argentina's fleet of this equipment is in Neuquén, Bahía Blanca and the Litoral.
See the evidence
Training one in Río Negro means bringing them in, or training them against machine hours that are not spinning yet. It is the same problem the corridor already has with certified welding, and there the province attacked it with public training.
See the remaining 2 risks
A single asset does not sustain a base: all three have to come online
With the midpoint at USD 4.1 M/yr split between gas compression, LNG compression and crude pumping, none of them alone covers the amortisation of instruments and crew. The niche is viable as a corridor base, not as the supplier of one plant. If LNG slips or the pumping is contracted turnkey from outside, the number breaks.
The 2-4 % annual maintenance intensity is a sector standard, not a Río Negro figure
It is the weakest link in the calculation and the province's three maintenance niches share it. There is no published O&M contract for the corridor to anchor it against, and the search for a rate per HP per year came up empty across four documents. When the first contract appears, this number gets recalculated.
The opportunity in depth
How to get inthe gap and the routes that open it
1We found no rotating-equipment service base established in the Río Negro corridor. Turbomachinery maintenance is bought today in Neuquén, in Bahía Blanca or directly from the factory. Distance plays differently depending on the machine: the Allen compressor plant, the largest in this niche, sits minutes away from the Neuquén bases, so there a Río Negro entrant does not win on proximity; the LNG stations and the Punta Colorada pumps, on the coast, are more than 400 km from Neuquén and from Bahía Blanca. The sector chamber's member list can be reviewed in full —33 companies— but it does not publish where each one has its workshop, so we declare the gap for what it is: not found, not proven.
2In the band that needs no factory authorization we have not identified anyone established here. Diagnostics, vibration analysis, laser alignment, borescopy, auxiliaries and control systems can be sold without being an authorized shop — and they are precisely the services an operator with a small crew cannot handle alone. The instruments are expensive but they can be bought; repairing gearboxes also needs a test bench.
3The crew is trained on a fleet, and the fleet is in another province. A turbomachinery technician does not come out of a course. But there is a pool almost nobody looks at: Catriel, with seventy years of oil trade and under a declared labour emergency because of the decline of conventional production. It is the same path the province already walked with certified welding.
4Ley 5805 calls for 60% Río Negro contracting and we have not identified any provincial supply of this service. A mandatory minimum with no identified supply on the other side is the exact definition of a window — but it closes when the first contract is signed, not when the asset starts up. And the 60% covers services, not only goods and works: unlike the national RIGI's local-content rule.

How much heavy work goes back to the factorythree of eleven overhauls, measured at the country's best-equipped operator
Where it isAllen, at kilometre 94.75 of the route: three Titan 130 turbocompressors, two running and one on standby
When you get paid, and what blocks it
High, and for a reason that is not budgetary: when a compressor stops, the gas does not flow. On a dedicated pipeline feeding a liquefaction plant with a vessel waiting, an unplanned shutdown does not translate into a maintenance cost but into cargo not exported, and that asymmetry is what holds the price of the service up. The same applies on the crude side: the terminal bills per vessel loaded. The buyer of this service does not compare quotes, it compares response times — and there proximity is worth more than the rate, which is exactly the argument for a base established along the corridor against a shop 500 km away.

split
The equipment manufacturersthe major overhaul and the original spare part
This is the hard ceiling of the niche thesis, and there is a measurement that sizes it instead of assuming it: TGN, which has been operating since 1992, in 2024 carried out eight compressor overhauls in house and contracted three more to Solar Turbines verif.
See the evidence
⇒ not even the country's best-equipped operator keeps all of the heavy work: a little over a quarter goes back to the manufacturer. Argentina's fleet of this type carries known brands —TGN's plants run Solar Mars 100 turbocompressors and Solar Saturn turbogenerators, and YPF's Loma de la Lata plant, which TGN overhauled, runs Ruston TB 5000 turbines with Rademakers gearboxes— so the spare part and the hot section have a factory owner. And the largest machine in the corridor, the new Allen plant, comes with
Titan 130 turbines
verif: the factory owner of its spare parts is the maker of that turbine.
The gas transmission companies, which sell this same service to third partiesthe full package whenever the operator does not build its own team
This is not a competition hypothesis: it is a declared business. TGN operates and maintains 11,222 km of pipeline when only 6,806 are its own verif, and books that sale on its own revenue line in its financial statements verif.
See the evidence
Its third-party portfolio includes Gasoducto del Pacífico Argentina, YPF Luz's Loma Campana, Tecpetrol's Fortín de Piedra, ENARSA's GNEA and GIJA, REMSA's Río de Las Burras compressor plant on the Salta puna and, since 2024, maintenance of the three turbocompressor units at YPF's Planta Turbo Expander in Loma de la Lata, awarded for two years. Whoever comes to Río Negro competes against that.
The operator itself, with an in-house maintenance crewthe daily routine and the standby duty
To operate the pipeline, the environmental impact study provides for two dispatch operators per shift, one mechanic and one electrical and instrumentation technician on day shift verif; in the provincial legislature 40 direct jobs in operation were mentioned prob. That crew covers routine and standby, not an overhaul or an instrumented vibration analysis thesis. It is an incumbent that occupies the floor of the work and leaves the ceiling outside — which is exactly where the margin sits.
The rotating-equipment shops of Neuquén and Bahía Blancatoday, everything the manufacturer does not do
This is the incumbent that travels, not the one that is there. Today they serve the corridor from outside because the asset does not exist yet; once it does, distance starts to cost: an unplanned compressor shutdown is measured in hours, and travel time enters the calculation. That is the gap a Río Negro base enters through, and Ley provincial 5.805 widens it.
The jobs it createsThe visible effect is the crew. A rotating-equipment base installs a trade along the corridor that is not there today —turbomachinery technician, vibration analyst, gearbox mechanic— and those profiles then serve any industrial asset in the area, not only the pipeline.the detail on jobs and trades
It is the flip side of the corridor's labour problem: operations employ very few people compared with construction, so what remains depends on those few jobs being high-skilled and located here rather than in Neuquén. And there is a natural candidate that already exists: the pool of trained oil workers in Catriel, a town with seventy years of the trade and under a declared labour emergency because of the decline of conventional production. Converting conventional production into maintenance of crude and gas transport and logistics is a short path, and we have not identified anyone building it.
How we
calculate it
The number is our own estimate. The calculation, step by step, is below.
The full calculation, step by step
Concentration High, and for a reason that is technical rather than commercial: whoever built the machine controls the spare part and the hot-section procedure, and whoever operates it controls access. Between those two ends there is a band —inspection, diagnostics, auxiliaries, gearboxes, controls and process-compressor repair— that in Argentina today is shared by a handful of shops and by the transport companies themselves. What makes Río Negro different is that we have not identified anyone there yet: the asset is finished in 2028 and we found no rotating-equipment service base established along the corridor.
The rule that moves it
Here the rule does not create the demand —a compressor has to be maintained either way— but it decides who can bill it from Río Negro, and in this line of work it bites harder than in others because there is no provincial supply to satisfy it:
See the underlying reading
enablesRio Negro local content: 60% of contracting to local suppliers
See the rule → This is the niche's widest door, for an arithmetic reason: the law calls for 60% Río Negro contracting —triple the 20% the RIGI demands, and where there «local» means Argentine while here it means from Río Negro— and in rotating-equipment maintenance we found no one to buy from inside the province.See the full legal grounds
Three points change how it is used: it has been in force since 1 September 2025, not since its June 2026 regulation; it covers services and not only goods and works, unlike the national RIGI's local-content rule; and it does not bind only the operator but also its contractors and subcontractors, with joint and several liability. A mandatory minimum with no identified supply to cover it is the definition of a window, and it closes when the first contract is signed.
enables80/20 local hiring: 80% of personnel with 2 years' residency in Rio Negro
See the rule → It is not «80/20»: they are three separate minimums —80% Argentine nationality, 80% domiciled in Río Negro with two years of continuous residence, and 20% women and gender-diverse people.See the full legal grounds
In this trade that rule is both the opportunity and the problem: it requires hiring people from Río Negro for a job that barely exists in Río Negro. That is why training is not an ornament of the business but part of the entry plan, and the pool of oil workers in Catriel is the candidate already inside the province. ⚠️ There is a release valve: the enforcement authority may waive the residence requirement for workers on hydrocarbon and energy projects inside the Cuenca Neuquina, by reasoned resolution — so the protection exists but is not absolute.
enablesRIGI adhesion: first province, clean and unconditional
See the rule → Río Negro was the first province in the country to adhere, and the three acts that create this asset hang from it. For a maintenance supplier the effect is not fiscal but calendar-related: the RIGI puts a deadline on the investment —31 December 2028— and that date sets when the corridor moves from construction to operation, which is when this niche starts billing.Where the number comes from
USD 1.6-8.4 M/yr at steady state, midpoint ~USD 4.1 M. Over the verified power of the compression block that is USD 13-60 per HP per year, midpoint ~USD 31 — a number that comes out of this calculation and that we did not find published in the four documents reviewed
See the calculation, the variables and how it was validated
With no published rate, the number is built from three factors applied to the asset's investment. Change one and the total is recalculated.
the USD 200-350 M of compression and pumping installed on Río Negro soil × 2-4 % of total annual maintenance × 40-60 % that turbomachinery takes on a machine that spins=USD 1.6-8.4 M/yr at steady state, midpoint ~USD 4.1 M
Compression and pumping investment in Río NegroUSD 200-350 millionannual review
The new compressor plant plus its uprating, the two LNG compressor stations, and the pumps at Allen and Punta Colorada. The HP figure and the uprating are verbatim from the Boletín Oficial; the split across the three blocks is our own estimate and is set out in the table above.
Annual maintenance intensity2 to 4 % of the investment per yearannual review
The weakest link in the calculation, and we say so: it is an oil & gas sector standard, not a Río Negro figure. The province's three maintenance niches share it so that three different multipliers do not emerge. When the corridor's first O&M contract appears, this gets recalculated.
Share taken by turbomachinery40 to 60 % of that maintenanceannual review
On an asset that is rotating by definition, the machine takes more than the structure: overhaul, process compressor, gearbox, controls and auxiliaries. The rest —supports, spools, structure— is counted by the corridor's metalworking shop, which for its part declares that it excludes rotating equipment.
Reality ceiling, so the number does not inflate~USD 22 M/yr, what TGN billslive data
What TGN bills for selling operation and maintenance to third parties, pipelines included: Ps 22,396.9 M in 2024, 5.9 % of its sales. It is the benchmark that says a single corridor cannot be worth a multiple of this.
How solid the number is estim
We started by looking for the price, and it is not published. The natural unit of this market is the maintenance cost per HP per year, so we went to the source for it: tgs's 2024 Annual Report and Financial Statements —205 pages, where «potencia instalada» appears zero times—, its fourth-quarter report, TGN's financial statements as at 31 December 2024, and the ENARGAS installed-power report. None of them publishes a price per HP. That decides the method: with no rate, the number is calculated over the asset's investment, not copied.The investment base, asset by asset, and where each line comes from:
| Río Negro asset | investment | provenance |
