Simply Wall Street Highlights MEP and On-Site Generation Exposure to US Data-Center Power Constraints

Simply Wall Street’s review of US infrastructure-linked equities frames data-center and AI load growth as a driver of demand for engineering execution and local power systems, particularly where grid interconnection is delayed or disrupted.

Legence was highlighted for engineering, installation and service work on critical HVAC and MEP systems, including at US data-center facilities. The review links expanding demand from data-center and technology customers to a record US$5.4 billion backlog and a 1.2x book-to-bill ratio in the first quarter of 2026. It also cites approximately US$757 million of Engineering & Consulting revenue and US$2.99 billion from Installation & Maintenance, though the review does not disclose the reporting periods or methodology for these figures.

Power Solutions International was identified as a supplier of gas engines and integrated generator systems for power-intensive industrial sites and data centers. According to the review, such systems can support facility operations when grid connections are delayed or interrupted. The article cites about US$676 million of revenue from engineered integrated electrical power-generation systems.

The review also points to Oakland, where AI and EV tenants are described as seeking access to power-intensive space. That reference does not establish that specific leases have been signed, capacity has been delivered, or power supply has been secured.

For data-center operators and investors, the underlying implication is that constrained grid access may elevate the importance of MEP execution, cooling, installation capacity and local generation alongside site acquisition. This is an analytical inference from the review rather than evidence of a specific data-center development. The ability to convert supplier backlogs into revenue may still depend on available power capacity and project timing.
