  Replacing Diesel in AI-Scale Data Centers: Gas Engines, Turbines, and Steam

  This article analyzes a sector-wide shift: data center operators are moving from diesel backup toward natural gas reciprocating engines, gas turbines, and packaged-boiler-fed steam turbines.

  • Main action: Data centers and AI campuses are substituting diesel with on-site natural gas engines and turbines (and, where gas-turbine lead times are long, packaged boilers feeding steam turbines). Key, verifiable project details: 15 Wärtsilä Energy 18V50SG engines to supply nearly 300 MW at an Ohio project; Caterpillar received a 2 GW order from American Intelligence & Power Corp. for the Monarch Compute Campus (West Virginia) using Cat G3516 fast-response gas generator sets, with the 2,250-acre site potentially adding up to 6 GW more; mobile turbine units (e.g., Dynamis trailer-mounted 8–70 MW units; DT24 = 24 MW at 13.8 kV) and Certarus CNG logistics are being used as interim solutions, with Certarus supplying over 120 MW now and an additional 135 MW project slated to start in 2027.
  • Background and implementation details:Gas-turbine lead times have lengthened (reports of delivery pushed to the end of the decade for some large models), prompting use of mobile turbines and packaged boilers; Rentech notes packaged boiler lead times of ~1 year and states packaged boilers can feed steam turbines at efficiencies comparable to gas turbines during peak hours. The Oracle/OpenAI Stargate Abilene project uses a mix of GE Vernova LM2500XPRESS and Solar Turbines Titan 350 units and could consume as much as 1.2 GW. Analyst Shen Wang (Omdia) projects ~60 GW of new AI data center power capacity per year by 2030. The article is an analytical sector overview rather than a single-entity press announcement.

  Investing in Energy’s ‘Anti-Fragile’ Future

  S2G Investments’ managing director Bala Nagarajan outlined the firm’s investment criteria and advocated for backing “anti-fragile” energy businesses that succeed on standalone economics rather than depending on policy incentives.

  • Main announcement/action: S2G’s Bala Nagarajan explained the firm’s thesis to prioritize businesses that are “cheaper, faster, better” than incumbents, avoid deals that depend on policy incentives, and favor grid-enhancing technologies (advanced conductors, grid-enhancing software, solid-state transformers). He cited portfolio company Aerones (robotic wind-turbine blade repair) as an example of an anti-fragile investment and described using AI tools to generate automated “red flag reports” for faster due diligence.
  • Background and additional details: Nagarajan referenced his 17-year investing career, an urgent near-term demand surge from AI data centers (“the demand for new electrons … is knocking on our doors today”), the market stress from tightening federal tax credit deadlines (Safe Harbor dynamics forcing smaller developers to sell or exit), and his view that natural gas is no longer a bridge fuel, which he says will increase demand for high-integrity carbon credits.

  Gas Turbine Supply Chain Bottlenecks Could Reshape the Generation Mix in 2030 and Beyond

  EPRI researchers John Shingledecker and Bobby Noble outline severe gas turbine supply chain bottlenecks affecting rotor forgings and hot-section blades.

  • Main announcement:EPRI researchers report that rotor forgings and hot-section blades are the primary bottlenecks due to limited suppliers and complex manufacturing; some large-frame turbines have been shipped without rotors or blades and fitted onsite later to keep construction schedules. Key timelines: utilities needing capacity by 2028 face backlogs extending to 2030, and orders for <20 MW turbines reached record highs in 2025.
  • Background and details:Qualifying new vendors offers no quick fix (process depends on OEM and component); competition for nickel superalloys and cobalt from battery demand is raising material costs; near-term responses include life extensions, repowering, turbine uprates (e.g., inlet fogging, advanced modifications with DOE/NETL collaboration exploring double-digit percent uprates), and accelerated adoption of modular/smaller units (30–100 MW peaker territory and <20 MW emergence).

  Transformers in 2026: Shortage, Scramble, or Self-Inflicted Crisis?

  Wood Mackenzie and POWER report that U.S. transformer supply remains structurally out of balance, with multi-year deficits in large power and generator step-up units even as manufacturers commit major North American investments.

  • Main findings and actions:Wood Mackenzie estimates a 30% shortfall for power transformers and 10% for distribution units in 2025, with demand increases since 2019 of 119% for power transformers and 274% for GSUs; lead times average 128 weeks for power transformers and 144 weeks for GSUs. Despite nearly $1.8 billion–$2.0 billion in announced North American manufacturing investments since 2023, major corporate commitments include Hitachi Energy (over $1 billion continental, CA$270 million Varennes expansion, $457 million South Boston, VA project due by 2028, $106 million Alamo, TN expansion), Siemens Energy ($150 million Charlotte plant, production targeted early 2027), Eaton ($340 million South Carolina facility targeting 2027), Prolec GE (more than $300 million), Virginia Transformer Corp. ($40 million), ERMCO (>$70 million), and Central Moloney ($50 million). Unit prices have also climbed: power transformers +77%, GSUs +45%, some distribution up to 95%.

  • Background, policy, and procurement details: Federal trade measures (copper tariffs up to 50%, expanded Section 232 steel/aluminum duties) and the budget package nicknamed “One Big Beautiful Bill” (phasing down some renewables credits and tightening FEOC rules) have raised input costs and domestic‑content constraints; federal/state incentives and site support are driving reshoring to Virginia, the Carolinas, Tennessee, and elsewhere. Counterpoints include broker Patrick Tarver of Bolt Electrical LLC, who argues “There is not a shortage” and attributes delays to utility/EPC procurement practices (qualification lists, vendor rules) rather than factory capacity; Tarver says he can deliver standard substation transformers in 12 to 14 months and typically charges 12%–15% over factory cost.
