Decreto 450/2025 · rewriting Leyes 15.336 and 24.065, ending CAMMESA as central buyer, 24-month transition to July 2027

Argentina · Poder Ejecutivo Nacional (Decreto 450/2025) · order · 2025

Where it stands: In force since 7 July 2025; Secretaría de Energía and CAMMESA rulemaking under way inside the 24-month transition

Signed on 4 July 2025 and published on 7 July 2025, Decreto 450/2025 approves the adapted text of Ley 15.336 and a consolidated Ley 24.065: distributors must buy through spot purchases and competitive term contracts instead of a single administered supply, the dispatch operator becomes a company whose state shareholding can fall to 10 percent with a veto, and the Secretaría de Energía has 24 months to transfer CAMMESA's energy and fuel contracts to demand and supply.

The problem

Two decades of emergency rules had turned Argentina's wholesale market inside out. CAMMESA, designed as a dispatch operator and clearing house, had become the counterparty that bought fuel, signed generation contracts on behalf of demand, and sold to distributors at a seasonal price fixed by the Secretaría de Energía far below cost, with the difference covered by the treasury. Generators were paid administratively set remuneration rather than market prices, term contracting between private parties had almost disappeared, and no distributor had an incentive or a mechanism to hedge. Rebuilding a market required changing the framework laws themselves, which the Executive could only do because article 162 of Ley 27.742 delegated the power for a fixed period.

What it does

Decreto 450/2025, dated 4 July 2025 and published in Boletín Oficial 35.701 on 7 July 2025, approves in Annex I the adaptations to Ley 15.336 and in Annex II the adaptations to Ley 24.065 together with its consolidated text, in force from publication. Electricity is redefined as a thing capable of commerce under the Civil and Commercial Code and purchases and sales as ordinary civil and commercial acts. A new article 12 bis of Ley 15.336 declares that local rules blocking pass-through of wholesale purchase cost to final tariffs, blocking payment of distributors' debts through the dispatch operator, or undermining the market's financial self-sufficiency interfere with federal objectives. In Ley 24.065, article 8 recognises the comercializador as a market agent and article 10 defines the gran usuario or usuario libre as anyone contracting supply independently for its own consumption; article 35 makes the Organismo Encargado del Despacho a joint-stock company, initially majority-owned by the Secretaría de Energía, with the state holding reducible by the Executive to 10 percent while retaining board participation and a veto, and directs it to execute freely agreed contracts between generators, traders, large users and distributors in a term market and to dispatch the remainder in a spot or opportunity market. Article 36 requires generators to be paid a uniform price per delivery point based on the system's economic cost, with the cost of unserved energy taken into account, and distributors to pay a uniform price stabilised every 90 days. Article 40(c) requires the distribution tariff's energy term to reflect both spot purchases and the weighted average of term contracts procured in competitive processes under rules the Secretaría de Energía must issue, itemised on the customer's bill. Article 39 bis declares that term-market contracts are necessary to national policy so that local measures obstructing or taxing them interfere with it. Article 3 fixes a 24-month transition from entry into force for rewriting the implementing rules, and article 4 orders the Secretaría de Energía during that period to promote hydrocarbon-market deconcentration so generators can contract their own fuel, secure collection from distributors, set thermal remuneration criteria that reward efficient fuel buying, establish the progressive transfer to distributors and large users of the power purchase contracts CAMMESA signed on behalf of demand, transfer CAMMESA's fuel contracts to supply, and review all of Los Procedimientos approved by Resolución 61/1992 to decide their repeal or an end date.

Market effect

This is the largest change to Argentine wholesale power since 1992 and it moves risk from the treasury to market participants. Once the contract transfer under article 4 is executed, a distributor's energy cost stops being a political number and becomes the weighted average of its own competitive term procurement plus spot exposure, which creates, for the first time in twenty years, real demand for hedges and a business for traders. Generators gain the ability to contract fuel directly and to sell forward to private counterparties instead of depending on administered remuneration, which raises the value of efficient combined-cycle and of flexible capacity and should compress the spread between the best and worst thermal operators. The 90-day stabilisation of the price distributors pay keeps a buffer against spot volatility but is far shorter than the old seasonal regime and passes cost changes through within a quarter. The state's ability to cut its stake in the dispatch operator to 10 percent while keeping a veto reframes CAMMESA as market infrastructure rather than a state trading desk. The risks are execution risks: the transfer of legacy contracts, many of them dollar-denominated PPAs with renewable and thermal plants, has to land on balance sheets that can carry them, and the whole reform sits on a delegated decree whose parent delegation has expired, so it is exposed to litigation and to a future Congress.

Key numbers

Publication and entry into force
Boletín Oficial 35.701 on 7 July 2025; in force from publication
Transition period
24 months from entry into force, to about 7 July 2027
Price stabilisation for distributors
Uniform price per reception point, stabilised every 90 days
State stake in the dispatch operator
Initially majority; reducible by the Executive to 10 percent with board participation and veto
Legal basis
Delegation in articles 161 and 162 of Ley 27.742

Who gains and who pays

  • Generators and traders (gains): Free term contracting, direct fuel procurement and marginal-cost-based remuneration.
  • Distributors (obligation): Must procure through competitive term contracts and spot, and carry transferred CAMMESA contracts.
  • Large users and self-suppliers (gains): Statutory right to contract supply independently and protection of term contracts from local obstruction.
  • CAMMESA (mixed): Becomes a company whose state stake can fall to 10 percent and loses its central purchasing role.
  • Provinces and local regulators (costs): Local rules blocking cost pass-through or term contracts are declared to interfere with federal policy.

Implementation

Everything that matters now happens in Secretaría de Energía resolutions and CAMMESA procedures during the 24-month window that ends in July 2027: the competitive-contracting rules for distributors required by article 40(c), the mechanism and timetable for transferring the legacy power and fuel contracts, the guarantee and collection regime that makes distributors bankable counterparties, the new thermal remuneration criteria, and the wholesale review of Los Procedimientos approved by Resolución 61/1992. The decree was reported to the Comisión Bicameral Permanente under article 6. Because the article 162 delegation lapsed in July 2025, no further decree can extend the rewrite, so any correction must come by resolution within the approved texts or by a new law. The practical milestone to track is the first competitive term-contracting round run by a distributor under the new article 40(c) rules.

Concerns

  • Legal exposure of a rewrite of two framework laws by delegated decree
  • Credit quality of distributors as counterparties once CAMMESA steps back
  • Sequencing risk in transferring legacy dollar PPAs and fuel contracts
  • Provincial resistance to the pass-through and term-contract supremacy clauses
  • Whether the 24-month transition is long enough to build competitive procurement capability

Dates to watch

  • 2026: Rules for distributors' competitive term contracting and the start of contract transfer
  • 2027-07: End of the 24-month transition period for rewriting the implementing rules

Tariff normalisation · the 2025-2030 five-year review for Edenor and Edesur and focused subsidies under Decreto 465/2024

Argentina · ENRE, now the Ente Nacional Regulador del Gas y la Electricidad, and the Secretaría de Energía · decision · 2025

Where it stands: Five-year tariff paths approved after the February 2025 hearings and applied through monthly schedules; focused subsidies operating by registration

After a decade of frozen tariffs, ENRE ran a full five-year review for the AMBA distributors, convened by Resolución ENRE 79/2025 with a public hearing on 27 February 2025, and set tariff paths applied from 2025 with monthly adjustments; in parallel Decreto 465/2024 replaced blanket energy subsidies with a focused regime for vulnerable households registered in a national scheme.

The problem

Edenor and Edesur hold the two federal concessions covering the Buenos Aires metropolitan area, about a third of Argentine electricity demand. Their regulated revenue, set in the 2016 integral review, was frozen from 2019 and eroded by inflation of several hundred percent, so investment fell far below the levels the concession contracts require and service quality deteriorated to the point where the regulator was paying customers compensation for outages of 15 hours or more. On the supply side the seasonal price charged to distributors covered a small fraction of the wholesale cost, with the treasury paying the difference to CAMMESA through subsidies worth around two percent of GDP, and the blanket subsidy went disproportionately to high-consumption households in the wealthiest districts.

What it does

On the distribution side ENRE issued Resolución 79/2025 convening a virtual public hearing under the Reglamento de Audiencias Públicas of Resolución ENRE 30/2004; the hearing was held on 27 February 2025 from 08:30 to 13:23 and streamed publicly, with the file open from 10 February and registration to 24 February, and it examined the proposals Edenor and Edesur filed for the next five-year period under the Revisión Quinquenal de Tarifas. Parallel reviews covered transmission, convened by Resolución ENRE 74/2025 with a hearing on 25 February 2025 and following the integral renegotiation opened by Resolución ENRE 223/2024, and independent transmitters under Resolución ENRE 80/2025 with a hearing on 26 February 2025. ENRE and ENARGAS then published the resulting tariff schedules together with the updated wholesale seasonal and gas reference prices, moving to a rolling monthly adjustment: the May schedule carried an average electricity increase of 2.4 percent alongside 2.52 percent for gas, the pattern that has governed subsequent months. On subsidies, Decreto 465/2024 replaced the generalised regime, which had accumulated overlapping special schemes, with the Régimen de Subsidios Energéticos Focalizados targeted at vulnerable users, building on the power article 177 of DNU 70/2023 gave the Secretaría de Energía to redesign subsidies principally by household income and to assign obligations to distributors in delivering them; households register through the Registro de Acceso a los Subsidios Energéticos and the Secretaría has repeatedly extended bonuses for the lowest-income band, including a 25 percent extraordinary gas bonus continued into June 2026. Article 161 of Ley 27.742 merged ENRE into the Ente Nacional Regulador del Gas y la Electricidad, which began assuming the functions of both predecessors from May 2026.

Market effect

The five-year review converts the AMBA distribution business from a politically administered loss-maker into a regulated asset with a defined revenue path to 2030, which is what any buyer, lender or new shareholder needs before committing capital to network investment; combined with monthly indexation it removes the lag that destroyed real revenue between reviews. For consumers the transition is steep: a household that lost its subsidy sees a bill that is several times its 2023 level in real terms, and the political durability of the path is the main risk to the whole reform sequence, since a future government could freeze again. For generators and CAMMESA the effect runs through the payment chain: a cost-reflective seasonal price plus a solvent distributor margin is what allows Decreto 450/2025 to hand procurement back to distributors at all, so the tariff review is a precondition for the market normalisation rather than a parallel track. The focused-subsidy design also changes demand behaviour at the margin, because households above the threshold now face something close to the real marginal cost of consumption for the first time since 2002.

Key numbers

Regulator
ENRE merged into the Ente Nacional Regulador del Gas y la Electricidad under article 161 of Ley 27.742, assuming functions from May 2026

Who gains and who pays

  • Edenor and Edesur (gains): A defined five-year revenue path with monthly indexation after a decade of frozen margins.
  • Generators and CAMMESA (gains): Cost-reflective seasonal prices and a solvent distribution margin shorten the payment chain.
  • Households above the subsidy threshold (costs): Face close to full cost after the end of blanket subsidies.
  • Registered low-income households (gains): Targeted bonuses under the focused-subsidy regime.
  • The national treasury (gains): Subsidy spending falls as prices approach cost recovery.

Implementation

The tariff schedules are published monthly by the regulator and by each distributor, combining the five-year distribution path with the updated wholesale seasonal price and transmission charges, and the bills itemise the energy, transport and tax components as article 40 of the consolidated Ley 24.065 requires. The focused-subsidy regime runs on registration rather than on category, so its coverage changes with each validation round and with the extraordinary bonuses the Secretaría de Energía renews month by month. The institutional variable through 2026 and 2027 is the ENReGE migration: the merged regulator is taking over ENRE and ENARGAS functions progressively, the predecessor sites remain live during the transition, and its first full tariff cycle will show whether the five-year paths survive intact. The expiry of the DNU 70/2023 tariff emergency on 31 December 2025 means further adjustments must rest on the ordinary Ley 24.065 process.

Concerns

  • Political durability of the five-year path through the next electoral cycle
  • Affordability for households just above the focused-subsidy threshold
  • Investment delivery and quality penalties under the renewed concession obligations
  • Institutional continuity during the ENRE and ENARGAS merger into ENReGE
  • Legal basis for monthly adjustments now that the tariff emergency has lapsed

Dates to watch

  • 2026: ENReGE completes the assumption of ENRE and ENARGAS functions and runs its first full tariff cycle
  • 2030: End of the five-year tariff period for Edenor and Edesur

Ley Bases 27.742 · delegated power to rewrite the electricity laws, the ENReGE merger and the RIGI investment regime

Argentina · Congreso de la Nación (Ley 27.742, Ley de Bases y Puntos de Partida para la Libertad de los Argentinos) · statute · 2024

Where it stands: In force since July 2024; the article 162 delegation exercised through Decreto 450/2025 and the RIGI adhesion window extended to 8 July 2027

Published on 8 July 2024, the Ley Bases delegated to the Executive the power to adapt Leyes 15.336 and 24.065 to seven stated principles, created the merged Ente Nacional Regulador del Gas y la Electricidad, and established the RIGI, a thirty-year tax, customs and exchange-stability regime for single-project vehicles investing at least US$200 million, with an adhesion window now running to 8 July 2027.

The problem

Argentina's electricity framework still rested on Ley 15.336 of 1960 and Ley 24.065 of 1992 as amended by two decades of emergency decrees, under which CAMMESA had become the effective sole buyer, prices were administratively set rather than marginal, and distributors bought at a stabilised seasonal price disconnected from cost. Rewriting two framework laws through Congress was not achievable, and no large investor would commit dollars to a twenty-year project in a country with capital controls, export duties and a history of retroactive tax changes. The government therefore asked Congress for delegated powers and for a statutory stability guarantee strong enough to be relied on by project finance.

What it does

Ley 27.742 was sanctioned in June and published on 8 July 2024. Article 161 creates the Ente Nacional Regulador del Gas y la Electricidad, which replaces and assumes the functions of the ENRE under article 54 of Ley 24.065 and of the ENARGAS under article 50 of Ley 24.076. Article 162 empowers the Executive, within the delegation period of article 1, to adapt Leyes 15.336 and 24.065 and their implementing rules on seven bases: opening cross-border electricity trade, guaranteeing free commercialisation and maximum competition with free choice of supplier for final users, moving dispatch to hourly economic marginal cost including the value of unserved energy, setting tariffs on the real cost of supply, itemising what the final user pays with the distributor acting as collection agent, developing transmission through open competitive mechanisms, and professionalising the sector's institutions, with the Consejo Federal de la Energía Eléctrica reduced to a non-binding advisory body. Title VII creates the Régimen de Incentivo para Grandes Inversiones. It applies to forestry, tourism, infrastructure, mining, technology, steel, energy, and oil and gas; adhesion is through a Vehículo de Proyecto Único whose sole purpose is one project; the minimum investment in computable assets is US$200 million, which the Executive may raise by sector up to US$900 million, with at least 40 percent to be spent in the first two years; projects that can make Argentina a new long-term supplier to global markets with at least US$1 billion per stage can be declared Long-Term Strategic Exports. Benefits include a 25 percent corporate income-tax rate instead of the general scale, exemption from export duties three years after adhesion (two for strategic-export projects), accelerated depreciation, accounting in US dollars under IFRS, and thirty years of tax, customs, exchange and regulatory stability from adhesion. The two-year adhesion window of article 168 was extended by Decreto 105/2026, published 19 February 2026, for one year from 8 July 2026.

Market effect

The delegation in article 162 is the more consequential half for the power market, because it is what Decreto 450/2025 used to rewrite Leyes 15.336 and 24.065 a year later; everything about hourly marginal pricing, free supplier choice and the end of CAMMESA's central purchasing traces back to these seven bases. The RIGI is what makes the resulting projects financeable. For an energy sponsor the binding constraints in Argentina have never been resource or cost but currency convertibility, export duties and the risk that the tax regime changes mid-build; thirty years of stability plus a 25 percent tax rate plus duty-free exports after three years changes the discount rate more than any tariff decision. The practical effect so far has been concentrated in Vaca Muerta oil and gas, LNG and mining rather than electricity, because power projects rarely reach US$200 million of computable assets in a single vehicle unless they are transmission lines or multi-hundred-megawatt wind or solar complexes with export logic. The extension of the adhesion window to 8 July 2027 gives large transmission and generation projects a further year to structure into the regime, and the single-project-vehicle requirement is shaping how sponsors carve up portfolios.

Key numbers

RIGI minimum investment
US$200 million in computable assets; Executive may set sector minimums up to US$900 million
Early-spend condition
At least 40 percent of the minimum investment in the first two years (reducible to no less than 20 percent)
Stability period
30 years of tax, customs, exchange and regulatory stability from adhesion
Corporate income tax
25 percent instead of the general scale; export duties waived after three years (two for strategic-export projects)
Adhesion window
Two years from entry into force, extended one year from 8 July 2026 by Decreto 105/2026

Who gains and who pays

  • Large energy, mining and LNG project sponsors (gains): Thirty years of tax, customs and exchange stability plus a 25 percent income-tax rate.
  • Provinces and municipalities (costs): Local rules that obstruct RIGI projects are declared absolutely void under article 165.
  • National treasury (costs): Reduced income tax, export duties and import duties on qualifying projects.
  • ENRE and ENARGAS staff and regulated parties (mixed): Merged into the Ente Nacional Regulador del Gas y la Electricidad under article 161.
  • Smaller developers below US$200 million (costs): Excluded from the regime and competing against stabilised rivals.

Implementation

The Executive used the article 162 delegation on 4 July 2025, days before it expired, issuing Decreto 450/2025 with the adapted texts of Ley 15.336 and the consolidated Ley 24.065. The ENReGE created by article 161 began progressively assuming the ENRE's and ENARGAS's functions from May 2026 and launched its own portal in September 2026, while the former agencies' sites continue to operate during migration. RIGI applications are resolved by the application authority within the Ministry of Economy, project by project, with the investment plan and the stability end-dates recorded in the approving act; Decreto 105/2026 extended the window to 8 July 2027. Watch for sector-specific minimum-investment decrees, the first electricity-sector RIGI approvals, and any challenge to article 165's voiding of provincial rules.

Concerns

  • Constitutional friction between article 165 and provincial jurisdiction over natural resources
  • Fiscal cost of thirty-year stability commitments across multiple sectors
  • Few electricity projects large enough to reach the US$200 million threshold in a single vehicle
  • Dependence of the market reform on a delegation that has now expired
  • Institutional capacity of the merged ENReGE during the migration from ENRE and ENARGAS

Dates to watch

  • 8 July 2027: End of the extended RIGI adhesion window
  • 2026: ENReGE completing the assumption of ENRE and ENARGAS functions

DNU 70/2023 · tariff emergency to 31 December 2025 and the energy deregulation title

Argentina · Poder Ejecutivo Nacional (Decreto de Necesidad y Urgencia 70/2023) · order · 2023

Where it stands: In force since December 2023 despite Senate rejection; the tariff emergency lapsed on 31 December 2025 and only the health emergency was extended

The Milei government's founding deregulation decree, published in the Boletín Oficial on 21 December 2023, declared a public emergency including tariffs until 31 December 2025, repealed the decrees and the law that underpinned the frozen-tariff and price-control regime, gutted the distributed-generation incentive law, and gave the Secretaría de Energía an express mandate to redesign electricity and gas subsidies around household income.

The problem

Argentina arrived in December 2023 with residential electricity tariffs frozen for most of a decade, wholesale prices covering roughly a quarter of the cost of supply, subsidies of about two percent of GDP paid through CAMMESA, distributors and generators in a payment chain that ran months behind, and a regulatory framework built out of emergency decrees stacked on Leyes 15.336 and 24.065 since 2002. There was no parliamentary majority for reform, so the incoming government used article 99(3) of the Constitution to move first and legislate later.

What it does

Decreto de Necesidad y Urgencia 70/2023, signed 20 December 2023 and published on 21 December 2023 in Boletín Oficial 35.326, declares in article 1 a public emergency in economic, financial, fiscal, administrative, pension, tariff, health and social matters until 31 December 2025, and in article 2 commits the state to the widest deregulation of commerce, services and industry, voiding restrictions on the supply of goods and services and any rule that distorts market prices. Title VIII, on energy, repeals Decreto 1060/2000, Decreto 1491/2002, Decreto 634/2003, Ley 25.822 and Decreto 311/2006, and repeals articles 16 to 37 of Ley 27.424, dismantling the fiscal-incentive machinery of the distributed-generation regime while leaving the right to inject. Article 177 empowers the Secretaría de Energía to redetermine the subsidy structure so that final users are assured access to basic and essential consumption of electricity under Leyes 15.336 and 24.065 and of natural gas under Leyes 17.319 and 24.076, based principally on household income, and to define the mechanisms, roles and obligations of distributors and other agents in delivering the subsidy. The decree was transmitted to the Comisión Bicameral Permanente under Ley 26.122; the Senate voted to reject it in March 2024 but the Chamber of Deputies never did, so under the rule that both chambers must reject it, it remains in force, with the labour chapter suspended by the courts. Decreto 942/2025, published 2 January 2026, extended only the health emergency to 31 December 2026, so the tariff emergency lapsed on 31 December 2025.

Market effect

The decree is the legal hinge of the entire 2024 to 2026 price normalisation. By declaring a tariff emergency it gave the Secretaría de Energía and ENRE cover to raise wholesale seasonal prices and distribution margins in steps that would otherwise have required the full audiencia pública and five-year review machinery, and by empowering income-based subsidy redesign it produced the segmentation regime that replaced blanket subsidies. For generators the immediate effect was the start of a real, if slow, improvement in the CAMMESA payment chain as the subsidy gap narrowed; for distributors it was the first sustained recovery of the valor agregado de distribución since 2019; for households it was a step change in bills partly offset by the targeted scheme. Repealing articles 16 to 37 of Ley 27.424 killed the tax credit and promotion fund for rooftop solar, which stalled Argentina's distributed-generation market at a very small base. The expiry of the tariff emergency at the end of 2025 matters for anyone modelling 2026 onward: adjustments now have to run through the ordinary Ley 24.065 process and the five-year review, which is exactly what ENRE and the successor Ente Nacional Regulador del Gas y la Electricidad are doing.

Key numbers

Emergency period
Declared to 31 December 2025; only the health emergency extended to 31 December 2026 by Decreto 942/2025
Publication
Boletín Oficial 35.326, 21 December 2023
Energy repeals
Decretos 1060/2000, 1491/2002, 634/2003 and 311/2006, Ley 25.822, and arts. 16 to 37 of Ley 27.424
Congressional status
Rejected by the Senate in March 2024; not rejected by the Chamber of Deputies, so still in force under Ley 26.122

Who gains and who pays

  • Generators and CAMMESA creditors (gains): Narrowing subsidy gap improves the wholesale payment chain.
  • Residential and small commercial users (costs): Tariff normalisation and the end of blanket subsidies.
  • Distributors Edenor and Edesur (gains): Recovery of the distribution margin under emergency-era adjustments.
  • Rooftop solar installers and users (costs): Articles 16 to 37 of Ley 27.424 repealed, removing the incentive regime.
  • Secretaría de Energía (obligation): Mandated to design an income-based subsidy scheme and its delivery mechanics.

Implementation

Implementation ran through Secretaría de Energía resolutions rather than the decree itself: quarterly seasonal-price schedules, the registration of households for targeted subsidies, and the 2024 and 2025 adjustments to distribution margins. Decreto 465/2024 then replaced the generalised subsidy regime with a focused one for vulnerable users, and the Régimen de Subsidios Energéticos Focalizados now runs on a registry to which households apply. The decree's own energy repeals are complete and not reversible except by law. Because the tariff emergency expired on 31 December 2025, the live questions are whether Congress revisits the decree, whether the courts extend the labour-chapter reasoning to other titles, and whether the distributed-generation incentives are restored by a new statute.

Concerns

  • Constitutional fragility of a decree rejected by one chamber and challenged in court
  • Loss of the distributed-generation incentive regime under Ley 27.424
  • Affordability of unsubsidised tariffs for households just above the subsidy threshold
  • Legal basis for tariff adjustments now that the emergency has lapsed
  • Reliance on decree powers rather than a negotiated statutory framework

Dates to watch

  • 31 December 2026: End of the extended health emergency under Decreto 942/2025
  • 2027: Continuing litigation and congressional treatment of the decree's remaining titles

Ley 27.191 renewable quotas · 8 percent by 2017 and 20 percent by 2025, RenovAr and the MATER term market

Argentina · Congreso de la Nación (Ley 27.191) and the Secretaría de Energía (RenovAr and MATER resolutions) · statute · 2017

Where it stands: Quota regime binding on large users; compliance now met almost entirely through MATER private contracts rather than new auctions

Ley 27.191 obliges every consumer, and individually every large user with 300 kW or more of demand, to source a rising share of its electricity from renewables (8 percent by end-2017, 12, 16, 18 and 20 percent by 31 December 2025); the state met it first through the CAMMESA-contracted RenovAr auctions, whose Round 2 was launched in 2017, and then through the MATER private term market, which is now the only route for new build.

The problem

Argentina entered the 2010s with a power mix that was more than 60 percent gas-fired, hydro that had not grown since the 1990s and renewables below 2 percent of demand, while the earlier Ley 26.190 target of 8 percent by 2016 had produced almost nothing because there was no enforceable obligation, no bankable offtake and no way to convert pesos into dollars for project debt. Developers would not build without a dollar-denominated contract backed by something better than CAMMESA's balance sheet, and large industrial users had no reason to buy renewable energy at all.

What it does

Ley 27.191, sanctioned on 23 September 2015 and promulgated in October 2015, rewrote Ley 26.190 to set a national target of 8 percent of electricity consumption from renewables by 31 December 2017 and 20 percent by 31 December 2025, with an interim ladder of 12 percent by 2019, 16 percent by 2021 and 18 percent by 2023, and made the level reached in each period a floor for the next. Article 9 makes wholesale-market Grandes Usuarios and large distribution customers with demand of 300 kW or more comply individually, either by self-generating or by contracting renewable energy from a generator, from a distributor acting on their behalf or from a trader. It also created the Fondo para el Desarrollo de Energías Renovables (FODER) as a trust to guarantee offtake and provide World Bank-backed payment and termination guarantees, plus fiscal benefits (accelerated depreciation, early VAT refund, a tax certificate for local content). The Executive implemented it in two phases: the RenovAr auctions, in which CAMMESA signed twenty-year dollar PPAs with FODER guarantees across Rounds 1 and 1.5 in 2016, Round 2 in 2017 and the MiniRen Round 3 in 2019; and the Mercado a Término de Energías Renovables (MATER), opened by Secretaría de Energía resolution in 2017, under which a large user contracts directly with a generator and CAMMESA allocates scarce transmission capacity through quarterly dispatch-priority assignment rounds. Non-compliant large users pay a penalty priced off the cost of the substitute supply.

Market effect

The quota created the only bankable renewable demand in Argentina. RenovAr cleared prices that fell from around US$60 per MWh in Round 1 to the US$40s in Round 2 for wind, which made Patagonian and Buenos Aires province wind the cheapest new generation in the country, and the FODER guarantee let sponsors raise international debt against a sovereign-linked instrument rather than CAMMESA receivables. Since 2019 no new RenovAr round has been called, so the entire build has shifted to MATER, where the binding constraint is not price but transmission: CAMMESA's quarterly allocation rounds regularly award far less capacity than requested because the high-voltage network out of Patagonia, Cuyo and the Northwest is saturated, and the projects that do get priority are those that can connect at 132 kV or co-locate with load. For an industrial buyer the arithmetic is simple: a MATER contract is normally cheaper than the regulated seasonal price plus the quota penalty, so compliance is bought rather than paid as a fine. The 20 percent target for 31 December 2025 was not reached, which leaves large users exposed to penalties and gives the government a reason to keep MATER allocation moving while it decides whether to re-auction.

Offtake support
FODER trust with World Bank-backed payment and termination guarantees on twenty-year dollar PPAs

Who gains and who pays

  • Wind and solar developers (gains): Twenty-year dollar PPAs under RenovAr and a private offtake market under MATER.
  • Large users with 300 kW or more of demand (obligation): Individual quota compliance or a penalty priced off substitute supply cost.
  • CAMMESA (obligation): Counterparty to RenovAr PPAs and administrator of MATER dispatch-priority allocation.
  • Transmission-constrained provinces (costs): Saturated high-voltage corridors cap how much MATER capacity can be allocated.
  • Industrial consumers buying through MATER (gains): Renewable supply typically below the regulated seasonal price plus penalty.

Implementation

The quota is enforced by CAMMESA through monthly settlement, which measures each obligated user's renewable share and applies the penalty where it falls short. RenovAr PPAs signed in 2016 to 2019 continue to run and a material share of the awarded pipeline was never built, so contracted volumes overstate delivered energy. New capacity now comes almost entirely through MATER: CAMMESA publishes the results of each quarterly dispatch-priority allocation round, and those results, not any auction calendar, are the leading indicator for Argentine renewable build. The wider market reform of Decreto 450/2025 does not repeal Ley 27.191, but by moving distributors toward competitive term contracting it changes how the quota interacts with the regulated environment, and the treatment of the missed 2025 target is an open decision for the Secretaría de Energía.

Concerns

  • Transmission saturation limiting MATER dispatch-priority allocation regardless of price
  • The 20 percent 2025 target missed, leaving penalty exposure unresolved
  • No new RenovAr round since 2019 and uncertainty over FODER's future
  • Currency and payment-chain risk in CAMMESA-intermediated contracts
  • Interaction between the quota and the market normalisation of Decreto 450/2025

Dates to watch

  • 2026: Quarterly CAMMESA MATER dispatch-priority allocation rounds and any penalty enforcement for the missed 2025 target
  • 2027: Expected decision on a post-2025 renewable obligation
