Behind-the-Meter Power Challenges for Datacenters
SemiAnalysis reports that behind-the-meter (BTM) power generation for AI datacenters has become mainstream, with 75GW of firm orders tracked, 20GW ordered in Q2 2026 alone. Major deals include Microsoft's 5GW with Chevron and Crusoe, Google's 930MW aeroderivative turbines and 900MW Bloom fuel cells, and OpenAI's 1.4GW campus with Jenbacher engines. The report details six key challenges: contracts & bankability, permitting, fuel supply, equipment procurement, workforce, and electrical physics. It highlights permitting delays (e.g., Oracle's Project Jupiter) and the rise of Energy-as-a-Service vendors like VoltaGrid. The analysis emphasizes the shift towards reciprocating engines and fuel cells, and the growing importance of balance-of-plant equipment.
This article provides unique, detailed analysis on the behind-the-meter power trend that is reshaping datacenter infrastructure for AI, a critical topic for the AdTech industry as digital advertising grows.

AI Power Rush: Data Centers Buy Used Jet Engines
The AI boom is driving data center operators to purchase used gas turbines and converted jet engines due to six-year lead times for new turbines. A Reuters analysis reveals that Siemens Energy, GE Vernova, and Mitsubishi Heavy Industries face capacity constraints. Anthropic has agreed to pay $3.4 billion for gas generators from Caterpillar, while SpaceX's xAI has invested nearly $3 billion in turbines. Companies like ProEnergy and FTAI Power convert aircraft engines into power-generating turbines, with orders from Crusoe and an unnamed cloud provider. The article highlights a market where demand exceeds supply, with delivery times stretching into the early 2030s, and notes environmental and regulatory challenges.
Big Tech Builds Natural-Gas Plants for AI
Major technology companies are investing in on-site natural gas power plants to secure large volumes of electricity for growing AI compute demand. Microsoft is partnering with Chevron and Engine No. 1 on a West Texas plant that could scale to 5 GW; Google is working with Crusoe on a 933 MW plant in North Texas; Meta added seven natural-gas plants at its Hyperion site in Louisiana, bringing that campus to 7.46 GW. Analysts warn of a turbine shortage and steep equipment-price inflation — Wood Mackenzie projects turbine prices could rise ~195% versus 2019 and notes multi-year delivery lead times with new orders constrained until 2028 and ~6-year delivery windows — creating supply-chain risks. Because natural gas fuels about 40% of U.S. electricity (EIA), these behind-the-meter builds could affect regional gas markets, electricity prices, other gas-dependent industries, and resilience during weather-driven supply shocks.
Electricity Is Becoming AI's Main Bottleneck
This Substack deep dive argues that in 2026 the AI industry's primary constraint is shifting from chips to power. Citing the IEA’s April 2026 report, the author notes global data-centre electricity demand grew 17% in 2025 and demand from AI-focused facilities grew 50%. The IEA projects data-centre consumption will rise from 485 TWh in 2025 to about 950 TWh by 2030. The piece outlines why capital alone cannot deliver the required gigawatts, how power pricing and contracts (including behind-the-meter deals) affect project economics, and the implications for turbine makers, power producers, site selection, and investors over the next three years.
