When a corporation decides where to site an industrial plant, a synthetic-fuels facility or a data centre, the question is no longer only how much a kilowatt-hour costs. It is also where that kilowatt comes from. In Uruguay (UY) that second question has an unusual answer for the region: according to preliminary figures attributed to the Ministry of Industry, Energy and Mining (MIEM) and reported by trade press, the country generated close to 99% of its electricity from renewable sources in 2024, split into 42% hydro, 28% wind, 26% biomass, 3% solar and just 1% fossil. On that physical base — an already-decarbonised grid — Uruguay is building two green business models worth reading through figures rather than slogans: green hydrogen and data centres powered by clean energy.
This analysis gathers what the available primary sources say — chiefly MIEM and multilateral bodies — and cleanly separates official data from project announcements and corporate statements. The aim is not to sell a country promise but to show where each number has an origin and a date, so that a company, a commercial owner or an investor can draw their own conclusions.
An almost carbon-free grid as raw material
The starting point for any green model in Uruguay is the make-up of its electricity matrix. The 2024 figure — close to 99% renewable, per preliminary data attributed to MIEM and cited by sector press (secondary source) — should be read alongside 2025’s, because the split shifts each year with hydrology. For 2025, regional environmental outlets (secondary source) report around 98% renewable, with 46% hydro, 34% wind, 14% biomass, 4% solar and 2% fossil. This is not a contradiction: when rainfall is lower, hydro generation gives ground and thermal back-up rises marginally. Both years should be read with their date; averaging them hides precisely the variable an investor needs to understand.
What matters for business is that, in either year, more than 90% of Uruguay’s electricity comes from renewable sources. For a company reporting emissions under Scope 2 (purchased electricity), locating on such a grid is a direct decarbonisation instrument: it does not need to buy offsets to «clean up» its power consumption, because the grid is clean at source. That difference — a low-carbon consumption by default, rather than by compensation — is what turns Uruguay’s matrix into something more than an environmental statistic: into a business input. It is the raw material on which the two bets below are built.
MIEM’s Green Hydrogen Roadmap
Green hydrogen — produced by electrolysis of water using renewable electricity — is the first of those bets. In Uruguay the framework is set by the Green Hydrogen Roadmap (Hoja de Ruta del Hidrógeno Verde), led by MIEM. According to the ministry itself and the International Energy Agency (IEA) policy record that catalogues it (primary sources), the hydrogen and derivatives industry could generate on the order of US$2 billion in revenue by 2040 (UY). This is a potential estimate contained in the base document, not committed revenue; it should be treated as such.
The technical basis of that roadmap is not an improvised in-house calculation. The document «Green hydrogen and the potential for Uruguay» was prepared by the Inter-American Development Bank (IDB) on an analysis by the consultancy McKinsey & Co., as recorded by the IEA and the IDB itself (primary sources, UY). That the analytical underpinning comes from a multilateral institution and an international consultancy is, in itself, a credibility signal for anyone assessing the framework: it reduces the risk that the potential figures are an optimistic projection from an interested party.
The plan also carries concrete, if initial-scale, financial backing. The European Union and the Government of Uruguay signed a declaration for a non-reimbursable contribution of US$2.2 million to strengthen the roadmap: capacity building, adaptation of the regulatory framework and an awareness plan, per MIEM and the IEA (primary sources, UY). It is worth reading where those funds go: they do not yet finance plants, but the institutional architecture — technical capacity and regulation — without which no private project advances. This is the kind of spending an investor should value, because a mature regulatory framework lowers the development cost of the first projects.
In parallel, a pilot competition offered up to US$10 million in non-reimbursable grants to design, finance, build and operate a pilot experience in hydrogen production and use (UY, primary source MIEM). The instrument is notable for its structure: it was run through the Green Hydrogen Sector Fund (Fondo Sectorial de Hidrógeno Verde), with participation from ANII (the National Research and Innovation Agency) and LATU (the Technological Laboratory of Uruguay). In other words, the state did not only put up money; it added the country’s innovation and technical-certification machinery. The winner was the consortium behind the «H24U» project. The reading for an investor is sober: Uruguay does not yet promise a consolidated industry, but it has ordered the framework — a multilateral technical document, start-up financing and a fund with competitive rules — so that the first projects can exist. This is the enabling phase, not the scale phase.
The projects that give the plan substance
The roadmap does not stay on paper. At the time of its publication, MIEM and the IEA (primary sources, UY) reported at least four announced green-hydrogen production projects: Tambor-Enertrag, HIF Global, H24U and Kahirós. What is interesting about that pipeline is not only its number but its diversity: the four do not compete for the same link but spread along the value chain, from hydrogen production for mobility and domestic industrial uses to export derivatives such as synthetic fuels. That distribution matters because it determines whether Uruguay will have, at once, local supply to consume and capacity to export.
The H24U project is the one arriving with explicit public backing, having won the Sector Fund’s pilot competition mentioned above (primary source MIEM, UY); its scope — design, financing, construction and operation of a pilot experience — is defined in the competition’s own terms. The other three — Tambor-Enertrag, HIF Global and Kahirós — appear in the official list of announced projects, but their progress, planned installed capacity and business model (domestic consumption versus export of derivatives) should be verified case by case with each developer’s own source. This is a deliberate caveat: project announcements are, by nature, a secondary source and evolve faster than official documents; taking a capacity or a start date as firm without confirming it with the developer is a common error with pipelines of this kind.
For a company that consumes energy or manufactures exportable goods, the existence of this pipeline matters for a practical reason: it determines whether, in the coming years, there will be local supply of green hydrogen and its derivatives — ammonia, methanol or synthetic fuels — without depending on imports. That is the link that turns a clean electricity grid into a decarbonised industrial input, rather than merely a low-emission electricity bill. For a manufacturer with process-decarbonisation targets — not only electricity targets — having local green hydrogen available could be the difference between meeting those targets and missing them.
Data centres: Google chooses Canelones for clean power
The second green bet has a more recognisable face. Google confirmed construction of a data centre in Canelones (UY), with an announced investment of US$850 million on a 30-hectare site in the Canelones Science and Technology Park, according to the company itself and specialist digital-infrastructure media (secondary source: Google statement reported by trade press). The figure is a corporate announcement, not a regulatory datum; it is cited as such.
The case is interesting precisely for what it revealed about the interplay of energy, water and territory. The initial design contemplated water cooling, with consumption that could reach 7.6 million litres of drinking water per day, which prompted environmental objections. After that review, the project was redesigned toward an air-cooled system (air-cooled chiller) that eliminates drinking-water consumption for cooling and caps electricity use at under 560 GWh per year, according to data-infrastructure media that followed the reconfiguration (secondary source, UY, 2024 data).
That change contains an engineering lesson every data-centre investor should internalise: there is a trade-off between water and energy. Air cooling usually consumes more electricity than water cooling, because it dispenses with evaporative cooling. In a country with a fossil grid, that extra consumption would translate into more emissions; in Uruguay, with a mostly renewable grid, the trade-off is far more favourable: some energy efficiency is sacrificed to eliminate the pressure on drinking water entirely, and that additional electricity is covered by clean power. The episode is also a reminder that a data centre’s green model turns not only on the source of the electricity but also on the water resource and on the social licence of the territory.
Why Uruguay? Google itself noted that the country’s clean grid — which it puts at around 97% renewable — was a factor in the siting decision, and that the data centre aims to run on more than 90% renewable energy in its balance (secondary source: Google statement, UY, 2024). It is worth flagging the difference between percentages here: the ~97% the company cites comes from its own reading of the grid and should not be conflated with MIEM’s annual figures (99% in 2024, ~98% in 2025) cited above, which correspond to different methodologies and periods. The underlying message for a digital-infrastructure investor is concrete: a renewable grid is not only a sustainability argument for the report, but a decision factor that one of the world’s largest technology companies stated it weighed when choosing where to put US$850 million.
How a company buys this clean energy
Both models above share an operational question: how is renewable energy contracted in Uruguay? The market structure is a structural datum (primary by institutional definition). Energy purchasing is ordered through participation in the market administered by ADME (Administración del Mercado Eléctrico), and in practice contracting with the state utility UTE is the dominant route for a large consumer. Specific cases and volumes of corporate power purchase agreements (PPAs) through ADME are not confirmed with disaggregated public data and should be requested directly from the operator before modelling a business case.
It is worth separating what is firm from what is not. Firm — a primary source — is the existence of the institutions: ADME administers the wholesale market and UTE is the dominant counterparty. Not confirmed with public data is everything a financial model actually needs: the price of a long-term PPA, the typical contract term, the specific conditions for a company to register as a large consumer and buy directly in the market rather than at the regulated tariff. That asymmetry — a clear framework, commercial parameters opaque until requested — is common in electricity markets and should not be read as an obstacle, but as due-diligence homework.
A complementary instrument that appears in these conversations is the guarantee of origin: a regulated electronic certificate attesting that one megawatt-hour was generated from a renewable source, often transferred together with a PPA (international definition, secondary source). For a company that needs to demonstrate renewable consumption to its parent group or against international reporting standards, this instrument is key, because it separates the «green» attribute from the physical electricity and makes it certifiable and transferable. However, the existence of a formalised guarantee-of-origin registry specifically in Uruguay is not confirmed in the sources reviewed; it is a point to verify with the relevant authority before assuming that mechanism is available locally. The practical conclusion is that the purchasing framework exists and is institutionalised — ADME and UTE — but the details that make or break an investment case require direct confirmation.
What locating in Uruguay means for a business
Put the preceding pieces together and the location argument Uruguay offers a corporation emerges. The investment-promotion agency Uruguay XXI positions the country as Latin America’s renewable-energy leader and speaks of a «new phase of strategic investments» (primary source, though promotional in nature, UY, 2024-2025); that claim should be read as what it is — an institutional marketing message — and set against the hard data already cited, which largely back it up without needing the slogan.
For a company, the argument translates into three concrete planes. First, compliance and reporting: a grid that is more than 90% renewable allows low-emission electricity consumption by default, useful for Scope 2, without depending on the purchase of offsets. Second, industrial input: the local green hydrogen under development opens the door to decarbonising processes and not only electricity, something the mere purchase of renewable power does not solve. Third, infrastructure predictability: Google’s decision to invest US$850 million in Canelones (secondary source: company announcement) works as a signal that demanding global players have already validated the country’s energy equation.
None of those three planes is a guarantee. Hydrogen is at the pilot stage; the renewable-grid argument depends on a hydrology that varies year to year; and the commercial terms of power purchasing demand case-by-case diligence. But taken together they compose something few markets in the region can offer with documentary backing: a genuinely clean grid, a hydrogen framework ordered by MIEM, and a concrete validation from a first-tier investor. That is the package a company evaluates when it asks where the kilowatt comes from.
Conclusions
Uruguay offers something uncommon: an electricity grid that is already more than 90% renewable — 99% in 2024 and close to 98% in 2025, per figures attributed to MIEM and sector press — and, on top of it, two green business models with documentary backing. Green hydrogen has a formal framework — MIEM’s roadmap, with a technical basis from the IDB on a McKinsey analysis, initial EU financing of US$2.2 million, a pilot fund of up to US$10 million run with ANII and LATU, and a potential estimated at around US$2 billion by 2040 — and a pipeline of at least four announced projects. Data centres have a concrete case: Google’s US$850 million investment in Canelones, redesigned toward air cooling and motivated, per the company, by the country’s clean power.
An honest reading separates levels of certainty. Regulatory frameworks and policy documents are primary and firm data. Project investment amounts and corporate statements are announcements — valuable but subject to change. And there are still open questions — the status of each hydrogen project, the local availability of guarantees of origin, the terms of a PPA through ADME — that a serious investor must verify at source before committing capital. Uruguay is not selling a finished promise; it offers a clean grid and an ordered framework to build on it. That distinction, more than any isolated percentage, is the one worth taking away.
