Power for AI: Grid Queues, Nuclear PPAs, Gas Turbines — 2026-09-17
BloombergNEF forecasts that US data center natural gas consumption will surpass the combined demand of Germany and Japan by 2035, driven by a projected 18 billion cubic feet per day requirement. Meanwhile, PJM capacity prices have hit their ceiling for the third consecutive auction, prompting regulators in Pennsylvania to warn of potential blackouts by 2030 if grid infrastructure does not accelerate.

Data centers to out-consume Germany and Japan for gas
BloombergNEF released a new outlook on September 14, 2026, predicting that US data centers will consume more natural gas than most nations within a decade. The report estimates gas demand from data centers could reach 18 billion cubic feet per day by 2035, a volume exceeding the combined consumption of Germany and Japan. This surge is directly linked to the AI boom’s insatiable need for reliable baseload power, intensifying pressure on US gas infrastructure and pipeline capacities.
PJM capacity prices hit ceiling amid reliability fears
PJM Interconnection’s capacity prices reached their regulatory ceiling for the third straight auction, highlighting a severe supply-demand imbalance as hyperscalers scramble for power. The persistent high prices underscore the urgency of the "Reliability Backstop Procurement" process, intended to address an approximately 60 GW capacity shortfall. Analysts warn that this trend increases the burden on state utility regulators to create new tariff structures to prevent shifting these massive costs from data centers to residential customers.
Pennsylvania regulators warn of blackouts by 2030
Pennsylvania public utility commissioners issued a stark warning that America’s AI gold rush is driving the nation’s largest power grid toward potential blackouts by 2030. The warning stems from the rapid expansion of data centers in the PJM region outpacing transmission and generation upgrades. Regulators are scrutinizing how large-load interconnections are managed, noting that without significant intervention, the grid cannot sustain the projected load growth while maintaining reliability standards.
German turbine maker Siemens Energy reports record orders
Siemens Energy reported a record order backlog of €162 billion, driven significantly by global demand for gas turbines and grid technologies for AI data centers. The company noted that demand for its gas turbines is so strong that delivery schedules are extending, with some slots booked years in advance. This backlog highlights the global bottleneck in heavy-duty turbine manufacturing, which remains a critical constraint on new gas-fired generation capacity worldwide.
Local view
Japan (Nikkei): In Japan, Kawasaki Heavy Industries’ chairman stated that inquiries for gas turbines are "active" due to strong data center demand. This sentiment reflects the global tightness in the turbine market, where Japanese manufacturers like Mitsubishi Heavy Industries and Kawasaki are seeing increased interest from international buyers seeking to bypass long lead times at other major suppliers. The Nikkei reports that this activity is part of a broader trend where utilities and independent power producers are securing equipment early to mitigate future supply chain risks.
Germany (Tagesschau): German researchers are actively working on methods to reduce the electricity consumption of AI models to alleviate strain on the grid. Tagesschau reports that while the demand for data centers is rising, scientific efforts are focusing on making AI algorithms more energy-efficient. These developments are seen as crucial for Europe, where energy costs and grid constraints are already limiting the rapid expansion of data center infrastructure compared to the US.
Context & numbers
- Gas Demand Projection: US data center gas demand is projected to reach 18 Bcf/day by 2035.
- Capacity Shortfall: PJM faces an estimated 60 GW capacity shortfall, addressed via backstop procurement.
- Investment Needs: Moody’s estimates that US data centers may require $110 billion in investment by 2030 to add 45 GW of power capacity.
- Nuclear PPA Pricing: Recent nuclear PPAs with hyperscalers are inferred to be priced around $110–115/MWh, reflecting a premium for carbon-free baseload reliability.
On the radar
- FERC Large Load Rulemaking: FERC has directed all six regional grid operators to justify or reform tariffs for data centers and other large loads. Stakeholders are expected to provide feedback on speed-to-power measures, with changes potentially in place by the end of 2026.
- SMR Deployment Timeline: Despite hype, industry experts warn that Small Modular Reactors (SMRs) will not significantly fill data center needs until 2029–2030, leaving a multi-year gap currently filled by gas and existing nuclear.
