AI may boom on gas power, then turn to nuclear

  • Spanish Market: Electricity, Natural gas
  • 13/01/25

The first tranche of new US data centers coming on line this decade to run electricity-intensive artificial intelligence (AI) software will probably rely mostly on power generated by natural gas, while the nuclear renaissance hoped for by Big Tech comes later in the 2030s.

Microsoft, Amazon, Facebook-parent Meta and Google-parent Alphabet want clean, reliable power as quickly as possible so they can be early movers in the development of AI, which is rapidly advancing and finding new user bases around the world. While these companies do not relish the optics of powering AI development with fossil fuels, gas-fired power is widely expected to fulfill most of the gap between current supply and future demand through at least 2030.

Unlike wind and solar, gas can be relied upon for steady, baseload power, a necessary ingredient for always-on data centers. And crucially, unlike nuclear, gas-related infrastructure can be built out quickly. The most recent additions to the US nuclear fleet, Vogtle units 3 and 4 in Georgia, took 15 years to build and cost $30bn, double the expected time and cost. A few decommissioned nuclear reactors can be restarted, as Microsoft is paying to do with a unit of Three Mile Island in Pennsylvania. But this low-hanging fruit will be quickly exhausted.

Questions around the meter

While there is broad agreement that gas will power the AI data center boom through at least 2030, questions remain about what this rapid gas-fired power build-out will look like.

Data center operators can secure power in two ways: wade through the long, arduous interconnection process through which new customers connect to the grid, or bypass the grid altogether and secure their own personal electricity supply through so-called "behind-the-meter" agreements. Many in the gas industry are betting tech companies' need for speed will force them to opt for the latter.

"The data centers are not going to wait," Alan Armstrong, chief executive of Williams, the largest US gas pipeline company, told Argus in an interview. "They are going to go to states that allow you to go behind the meter."

In this scenario, construction of an AI data center in a state like Louisiana, for instance, might accompany construction of a new intrastate pipeline connecting the state's prolific Haynesville gas field with a new gas-fired power plant. Intrastate pipelines bypass the federal oversight triggered by interstate pipeline construction, and new gas power plants only take 2-3 years to build, East Daley Analytics analyst Zachary Krause told Argus. Most of the incremental power needed to run AI data centers this decade will be generated by new gas plants, Krause said.

Even ExxonMobil in December said it was in talks to provide "fully islanded" gas-fired power to AI data centers. It claimed it could even capture 90pc of the CO2 emissions from power generation, appeasing tech companies' climate ambitions.

ExxonMobil's non-grid gas generation fleet is "independent of utility timelines, so they can be installed at a pace that other alternatives — including US nuclear — just can't match," ExxonMobil chief financial officer Kathy Mikells said.

But connecting to the grid may offer better reliability and economics than behind-the-meter gas power. If an off-grid gas generator trips off line, for instance, an always-on data center without back-up generation depending on that facility would be in trouble. Grid connection also allows generators to sell excess power into the grid. For those reasons, most new data centers this decade will rely on the grid as their primary power source, Adam Robinson, research associate at consultancy Enverus, told Argus.

Small modular future

But if the 2020s become the decade of gas-powered AI, the 2030s may be when nuclear-powered AI gets its due.

The long-awaited nuclear renaissance may come not from conventional reactors, but from next-generation small modular reactors (SMRs), which can theoretically be built much faster and cheaper. No US SMRs yet exist, but given the number of SMR start-ups with expected start dates before 2030, and money pouring into the sector from the likes of Google and Microsoft, at least one of these next-generation reactors should be operating by 2030, Adam Stein, director of nuclear energy innovation at research center Breakthrough Institute, told Argus. SMRs' smaller price tag relative to conventional 1 GW nuclear reactors may also accelerate their adoption, Stein said.

"Not every utility needs a GW-scale plant of any kind, but they might need a 300 or 600MW plant," he said. "So the total addressable market is larger for SMRs."

EU Parliament approves delay to climate policies

EU Parliament approves delay to climate policies

London, 3 April (Argus) — The European Parliament today voted to postpone the application of the corporate sustainability due diligence directive (CSDDD) and the corporate sustainability reporting directive (CSRD), with final approval now required from the European Council. The European Parliament has backed some of the key proposals from the European Commission's omnibus package submitted in February , which aims to delay the start of due diligence and sustainability reporting requirements by one and two years, respectively. The CSDDD would require large firms to adopt plans to mitigate their climate impact, keeping global temperatures within 1.5°C of pre-industrial levels, as per the Paris climate agreement. Under the new proposals, member states have until July 2027 to transpose the rules into national legislation, with the first wave of affected business required to be compliant from 2028. The CSRD came into force at the beginning of 2024, introducing mandatory climate and energy disclosures for some businesses. The use of certificates such as guarantees of origin and renewable power purchase agreements are the only ways recognised in the original text to document use of renewable energy. February's omnibus package sought to delay the start of reporting for companies with more than 250 employees as well as small and medium-sized enterprises by two years to 2028 and 2029, respectively. The next step in the legislative process requires formal approval from the European Council, which already indicated an agreement in an initial position adopted on 26 March. In addition to delaying the application dates, the commission is also seeking to amend the content and scope of both directives. Notably, for sustainability reporting, the changes would see 80pc of companies falling outside the initial scope .

South Korea’s GS Energy seeks term LNG from 2028

Singapore, 3 April (Argus) — South Korean private-sector firm GS Energy's subsidiary GS Energy Trading Singapore is seeking LNG deliveries starting from 1 January 2028, over a 5-15 year period. The first round of offers will be due on 25 April and the second to close on 1 August later this year. The firm has requested volumes of up to 0.81mn t/yr in 2028 and up to 0.97mn t/yr from 2029 onwards. This is equivalent to around 13-14 cargoes/yr in 2028 and about 16-17 cargoes/yr from 2029 onwards, assuming an average LNG cargo size of 60,000t. The cargoes will be delivered to the country's 10.8mn t/yr Boryeong terminal, which is owned by power producers SK E&S and GS Energy. The firm has also specified for offers to be linked to Brent or a hybrid of Brent and Henry Hub. South Korean utility Korea South-East Power in June 2024 also signed an agreement with TotalEnergies for a five-year term delivery of up to 500,000 t/yr of LNG to South Korea from 2027. Meanwhile, state-owned gas incumbent Kogas is expected to operate with a smaller pool of long-term LNG supplies from 2025, with the government granting it more flexibility in its procurement strategy. Long-term contracted supply volumes may typically be priced at a higher premium, and could be deemed as a small price for buyers to secure supply security, traders said.

Australia’s gas leaders hit out at market intervention

Sydney, 2 April (Argus) — Senior figures in Australia's upstream gas sector have hit out at plans for intervention in the heavily regulated industry, as debate continues on how to best address domestic supply shortfalls later this decade. The federal Coalition in March announced National Gas Plan including a 50-100 PJ/yr (1.34bn-2.68bn m³/yr) domestic reservation system aimed at forcing the three LNG exporters based in Queensland's Gladstone to direct more supply to the eastern states' market. But oversupplying the market to drive down prices would destroy the viability of smaller gas projects, Australian independent Beach Energy's chief executive Brett Woods said at a conference in Sydney on 1 April. The domestic-focused firm, which will export some LNG volumes via its Waitsia project in 2025, warns that such a move by the Peter Dutton-led opposition would reduce export incomes while harming Australia's international reputation. The volumes impacted by the policy could reach around 900,000-1.8mn t/yr. Expropriation of developed reserves is equivalent to breaking contracts with LNG buyers and with the foreign and local investors that the country needs for ongoing economic security, Woods said on 1 April. Domestic gas reservation systems put in place by the state governments of Western Australia (WA) and Queensland, designed to keep local markets well supplied, were "clearly supportable", Woods said, but only future supply should be subject to the regulations. LNG terminals, which represent about 70pc of eastern Australia's total gas consumption and shipped 24mn t in 2024 , should not be blamed for the failure of governments to expedite new supply and plan for Australia's gas future, head of Shell Australia Cecile Wake said in response to the Coalition's proposal. Shell's QGC business supplied 15pc of its volumes to the local grid, with the remainder shipped from its 8.5mn t/yr Queensland Curtis LNG project, Wake added. Canberra has moved to promote gas use as a transition fuel to firm renewable energy in line with its 2030 emissions reduction targets, but progress has been slow as reforming laws appear to be hampering development . The state governments, particularly in gas-poor Victoria and New South Wales (NSW), must recognise the need for locally-produced supply and streamline the approvals processes, especially environmental permits, executives said. But despite pleas for an end to years of interventionist policy — including the governing Labor party's measures to cap the price of domestic gas at A$12/GJ , Australia's fractured political environment and rising cost of living has sparked largely populist responses from its leaders. A so-called "hung" parliament is likely to result from the 3 May poll , with a variety of mainly left-leaning independents representing an anti-fossil fuel agenda expected to control the balance of power in Australia's parliament. LNG debate sharpens Debate on the causes of southern Australia's gas deficit has persisted, and the ironic outcome of underinvestment in gas supply could be LNG re-imports from Gladstone to NSW, Victoria and South Australia, making fracked coal-bed methane — liquefied in Queensland and regasified — a likely higher-emissions alternative to pipeline supply. Several developers are readying for this possibility , which is considered inevitable without action to increase supply in Victoria or NSW, increase winter storages or raise north-south pipeline capacity. Australian pipeline operator APA appears to have the most to lose out of the active firms in the gas sector. APA chief executive Adam Watson this week criticised plans for imports, because relying on LNG will set the price of domestic gas at a detrimental level, raise emissions and decrease reliability of supply, Watson said. The firm is planning to increase its eastern pipeline capacity by 25pc to bring new supplies from the Bass, Surat and Beetaloo basins to market. But investment certainty is needed or Australia will risk needing to subsidise coal-fired power for longer if sufficient gas is unavailable to back up wind and solar generators with peaking power, Watson said.

LNG stocks at Japan’s power utilities rise

LNG stocks at Japan’s power utilities rise

Osaka, 2 April (Argus) — LNG inventories at Japan's main power utilities increased during the week to 30 March, as warmer weather reduced electricity demand for heating purposes and limited gas-fired generation. The utilities held 2.24mn t of LNG on 30 March, up by 22pc from a week earlier, according to a weekly survey by the trade and industry ministry Meti. This was higher by 51pc compared with 1.48mn t at the end of March 2024 and up by 10pc against 2.03mn t — the average end-March stocks over 2020-24. A seasonal rise in temperatures weighed on power demand, which fell by 12pc on the week to 87GW across 24-30 March, according to the Organisation for Cross-regional Co-ordination of Transmission Operators (Occto). This resulted in a 24pc fall in gas-fired output to an average of 24GW during the period, the Occto data showed. Coal- and oil-fed generation also fell by 14pc to 23GW and by 21pc to 409MW respectively in the same period. The lower demand has created extra supplies to be sold on the wholesale market. This has weighed on day-ahead prices on the Japan Electric Power Exchange (Jepx) and worsened generation economics for the country's thermal power plants. Margins at a 58pc-efficient gas-fired unit running on oil-priced LNG supplies fell into negative territory, with the spark spread averaging at a loss of -¥2.28/kWh ($15.22/MWh) across 24-30 March, compared with the previous week's profit of ¥0.84/kWh. The 58pc spark spread using spot LNG widened the deficit, with the margin averaging at a loss of -¥3.79/kWh against the previous week's -¥0.80/kWh, based on the ANEA — the Argus assessment for spot LNG deliveries to northeast Asia. Coal remained competitive in Japan's merit order. But the dark spread of a 40pc-efficient coal-fired unit also fell by 64pc on the week to an average of ¥1.63/kWh over 24-30 March, based on Argus' spot coal and freight assessments.

Next US tariffs to take effect 'immediately'

Next US tariffs to take effect 'immediately'

Washington, 1 April (Argus) — President Donald Trump plans to announce a sweeping batch of tariffs on Wednesday afternoon that will take effect "immediately", the White House said today. Trump will unveil his much anticipated tariff decision Wednesday at 4pm ET during a ceremony at the White House Rose Garden. While the administration has announced the effective date, there is little clarity on what goods will face tariffs at what rates and against which countries, leaving the government agencies that will be tasked with enforcing new tariffs largely in the dark. "The president has a brilliant team of advisers who have been studying these issues for decades, and we are focused on restoring the golden age of America and making America a manufacturing superpower," the White House said today, brushing off criticism from economists, industry groups and investors. Economic activity in the US manufacturing sector contracted in March as businesses braced for Trump's tariff threats. Trump has previewed or announced multiple tariff actions since taking office. The barriers in place now include a 20pc tariff on all imports from China, in effect since 4 March, and a 25pc tax on all imported steel and aluminum, in effect since 12 March. A 25pc tariff on all imported cars, trucks and auto parts, is scheduled to go into effect on 3 April, the White House confirmed today. Trump and his advisers have previewed two possible courses of action for 2 April. Trump has suggested that all major US trading partners are likely to see a broad increase in tariffs in an effort to reduce the US trade deficit and to raise more revenue for the US federal budget. But Trump separately has talked about the need for "reciprocal tariffs", contending that most foreign countries typically charge higher rates of tariffs on US exports than the US applies to imports from those countries. In that scenario, high tariffs become a negotiating tool to bring down alleged foreign barriers to US exports. Treasury secretary Scott Bessent told Fox News on Monday night that the second course is the one Trump is more likely to take. Trump will announce "reciprocal tariffs" and "everyone will have the opportunity to lower their tariffs, lower their non-tariff barriers, stop the currency manipulation" and "make the global trading system fair for American workers again", Bessent said. But the White House insisted today that the new tariffs will not be a negotiating tool. Trump is "always up for a good negotiation, but he is very much focused on fixing the wrongs of the past and showing that American workers have a fair shake", the White House said. Trump's words and actions already have drawn retaliatory tariffs from Canada and China, and the EU is preparing to implement its first batch of counter-tariffs in April. Trump, for now, has deferred his tariff plans for imported Canadian and Mexican oil and other energy commodities. But the US oil and gas sector, which depends on pipelines and foreign-flagged vessels to transport its crude, natural gas, refined products and LNG, will feel the effects of tariffs on imported steel and proposed fees on Chinese-made and owned vessels calling at US ports.
