Power for AI: Grid Queues, Nuclear PPAs, Gas Turbines — 2026-09-08
Pennsylvania regulators have issued a stark warning that data centers will drive nearly 19% annual electricity demand growth through 2030, with natural gas expected to supply 59% of the state's power. Meanwhile, Siemens Energy reported a record €162 billion backlog driven by AI infrastructure demand, and utilities across the US are seeking $18.6 billion in rate hikes in H1 2026 alone to cover grid upgrades.

Pennsylvania PUC Forecasts 19% Annual Demand Growth
On September 2, 2026, the Pennsylvania Public Utility Commission (PUC) released new projections indicating that data centers will cause nearly 19% annual growth in electricity demand over the next five years. The commission noted that while residential and commercial usage will grow modestly, industrial demand—driven by hyperscale facilities—is forecast to soar. Natural gas is projected to supply 59% of Pennsylvania’s power to meet this surge, reinforcing the critical role of gas-fired generation in the short-to-medium term as nuclear capacity lags.
Siemens Energy Backlog Hits €162 Billion on AI Demand
Siemens Energy reported a record order backlog of €162 billion as of early September 2026, driven largely by demand for gas turbines and grid technology for AI data centers. The company’s gas turbine segment is particularly constrained, with new orders for turbines reaching 12.5 GW, highlighting a global supply bottleneck that is pushing delivery dates further out. This surge underscores the "turbine shortage" narrative, where manufacturers like Siemens, GE Vernova, and Mitsubishi Heavy Industries are struggling to keep pace with hyperscaler requests for behind-the-meter power.
US Utilities Seek $18.6 Billion in Rate Increases in H1 2026
Data center load growth is significantly impacting consumer costs, with US utilities requesting $18.6 billion in electricity rate increases in the first six months of 2026 alone. This figure already exceeds half of the record $29 billion in requests filed in all of 2025. Residential electricity rates have risen 7.3% nationally over the past year, prompting regulatory scrutiny on how grid upgrade costs are allocated between hyperscalers and retail customers.
Nuclear Sector Sees Investment Surge Despite SMR Skepticism
Despite skepticism about the timeline for Small Modular Reactors (SMRs), the nuclear sector is seeing significant investor interest, with stocks like NuScale Power (SMR), Oklo (OKLO), and GE Vernova (GEV) highlighted as key plays for AI energy demand in September 2026. However, experts caution that existing nuclear plants and gas are the only immediate solutions for current load growth, with SMRs unlikely to contribute meaningfully until post-2030. The disconnect between hype and deployment timelines remains a key theme in utility planning.
Local view
Germany: German financial media are closely watching Siemens Energy’s order book, with Börse Express noting the €162 billion backlog confirms strong global demand for energy infrastructure. Deutschlandfunk reports growing local resistance in the US against data center construction due to noise and power consumption concerns, which could slow project approvals for European tech firms expanding abroad.
Japan: Japanese outlets highlight the critical bottleneck in gas turbine production. Nikkei and Yomiuri have previously reported Mitsubishi Heavy Industries’ plan to double production capacity by 2030, but current coverage emphasizes that even this expansion may not meet the immediate surge from US and Asian data centers. Gigazine notes that GE Vernova has stopped accepting orders for 2031 deliveries, signaling extreme tightness in the supply chain.
Context & numbers
- PA Demand Forecast: Nearly 19% annual increase in electricity demand over the next 5 years due to data centers.
- US Rate Requests: $18.6 billion in rate increase requests in H1 2026.
- Siemens Backlog: €162 billion total order backlog; 12.5 GW of new gas turbine orders.
- Gas Turbine Lead Times: GE Vernova reports delivery schedules extending to 2031, with no new orders accepted for that year.
On the radar
- FERC Show-Cause Responses: Watch for FERC decisions on the six RTO show-cause responses (EL26-67 through EL26-72) regarding large load integration tariffs, which could reshape interconnection queues for data centers.
- PJM Reliability Backstop: PJM is preparing its extra capacity auction ("Reliability Backstop Procurement") starting September 2026 to address a ~60 GW shortfall, which may set new price floors for capacity resources.
