Switchgear Lead Times, Eaton’s $30 M Plant, 5-Year Delays from GE & Siemens, and 50% Project Cancellations (2021 to 2026)

Industry Risks: Procurement Shifts From Months to Years, Delaying 50% of Data Center Projects

The primary risk to energy and data infrastructure projects is no longer permitting or financing, but the multi-year lead times for critical electrical equipment, forcing a fundamental change in procurement strategy. Prior to 2024, developers operated on a sequential timeline, ordering switchgear and transformers months before required; now, they must procure these items years in advance, shifting significant capital risk upfront and threatening the viability of projects that fail to adapt.

• In the 2025 to 2026 period, lead times for large power transformers ballooned to between 3 and 5 years, a stark contrast to the approximate 12-month wait time common before 2024. This has become the single greatest chokepoint for connecting new power generation and data centers to the grid.
• The impact is most acute in the data center sector, where analysts estimate that between 30% and 50% of global capacity scheduled for 2026 will be delayed or cancelled specifically due to power infrastructure shortages, a risk that was negligible in the 2021-2023 period.
• In response, project developers are now ordering critical components like transformers and switchgear 12 to 24 months before construction begins, a complete reversal of historical project management and a direct consequence of the supply chain breakdown.
• This new procurement reality is compounded by skilled labor shortages, with substation engineers and transmission project managers now among the most difficult infrastructure roles to fill in 2026, creating delays even when equipment is secured.

OEM Investments: Eaton’s $30 M Plant and ABB’s 120% Capacity Boost Lag Behind Demand

Major equipment manufacturers are responding to the demand surge with significant capital investments to expand production, but these new facilities will not come online fast enough to alleviate the bottleneck before 2027. While OEMs like Eaton, ABB, and Hitachi Energy are increasing capacity, the scale of these expansions is insufficient to meet the combined demand from grid modernization, electrification, and the AI-driven data center buildout in the near term.

• Eaton announced a $30 million investment in April 2026 to build a new U.S. facility for medium-voltage switchgear, but the plant is not expected to be operational until 2027, offering no relief for projects planned in 2026.
• In February 2026, ABB initiated plans to increase its low-voltage switchgear production capacity by 120% across its European facilities, a direct move to address the escalating order backlogs from industrial and utility customers.
• Hitachi committed a historic USD 1 billion in September 2025 to expand its manufacturing of critical grid infrastructure, including transformers, highlighting the scale of investment required to address the structural supply deficit.
• Similarly, GE Vernova is working to increase its gas turbine production to 24 GW by 2028, indicating the multi-year timeline required for meaningful capacity additions in adjacent heavy electrical equipment markets.

Partnership Analysis: Energy Vault’s 1 GW Astor Enerji Deal Shows Supply Chain Focus

In response to extreme lead times, project developers are shifting from transactional purchasing to forming strategic partnerships and vertical integration to secure their equipment supply chains. This marks a structural change from the 2021-2024 period, where equipment was largely treated as a commodity; now, securing manufacturing slots via direct alliances is a primary competitive advantage for companies like Energy Vault and Crusoe Energy Systems.

• In August 2025, energy storage developer Energy Vault formed a global strategic partnership with Turkey’s Astor Enerji, which includes the procurement of 1 GW of transformers and the deployment of 2 GWh of battery systems, locking in a supply of critical hardware.
• Data center developer Crusoe Energy Systems is vertically integrating by manufacturing essential electrical equipment and switchgear in-house, a move designed to bypass external supply chain bottlenecks entirely for its projects.
• The procurement strategies of hyperscalers like Amazon, Google, and Microsoft are reshaping the market, as their willingness to sign long-term offtake agreements gives them preferential access to limited manufacturing capacity.

Geography: U.S. and EU Policies Drive Regional Switchgear Manufacturing Push

The switchgear and transformer bottleneck is a global issue, but government intervention and regional demand are creating distinct geographical centers for manufacturing investment and regulatory action. While Asia-Pacific remains a key growth market for demand, policy initiatives in the U.S. and Europe are now actively shaping where new production capacity for high-voltage equipment is being built.

• In the U.S., the government invoked the Defense Production Act (DPA) in April 2026 to bolster domestic production of transformers and other grid components, coupling this with billions in funding from programs like the Grid Resilience and Industry Grants to incentivize onshoring.
• The European Union’s F-gas regulation, which bans new SF 6-based medium-voltage switchgear starting January 1, 2026, is forcing a major technology transition and creating a protected market for manufacturers of SF 6-free alternatives.
• Canada is deploying tens of billions in Investment Tax Credits (ITCs) to support its clean electricity grid, creating a powerful demand signal for equipment needed for grid modernization and renewable integration projects.
• Asia-Pacific is forecast to be the fastest-growing region for Gas-Insulated Switchgear (GIS), with the market projected to expand at a 6.5% CAGR through 2031, indicating intense localized demand that will further strain global supply chains.

Technology Maturity: Core Switchgear at TRL 9, But SF 6-Free Shift Creates Supply Pressure

The underlying technology for transformers and switchgear is mature and fully commercialized (TRL 9), meaning the current crisis is a failure of industrial capacity, not a technological one. However, a mandatory regulatory shift away from SF 6 gas in the EU is creating a major product replacement cycle, adding further pressure to a supply chain already struggling to meet baseline demand from grid expansion and data center growth.

• The primary technology challenge for OEMs is scaling up manufacturing for existing, proven designs, a process that takes years due to factory construction times and the need to secure specialized materials like grain-oriented electrical steel.
• Driven by the EU’s F-gas regulation, manufacturers like Schneider Electric, ABB, and Siemens Energy are rapidly scaling production of switchgear that uses alternatives to the potent greenhouse gas sulfur hexafluoride (SF 6), representing a significant product cycle refresh.
• Innovation is focused on digitalization, with “digital switchgear” integrating sensors and software for predictive maintenance and grid optimization, which increases the value proposition and drives replacement demand for aging assets.
• Emerging technologies like Solid-State Transformers (SSTs) and High-Temperature Superconducting (HTS) cables (TRL 6-8) offer future solutions but are not commercially ready to alleviate the current bottleneck and are at least 5-10 years from widespread deployment.

Scenario Modelling: OEM Backlogs Are The Critical Signal for 2026-2027

The most critical forward-looking indicator for the duration of the equipment bottleneck will be the quarterly order backlogs and book-to-bill ratios reported by major OEMs like GE Vernova, Siemens Energy, and Eaton. A sustained stabilization or reduction in reported backlogs, particularly for large power transformers, would be the first concrete signal that manufacturing capacity is beginning to catch up with demand.

• If lead times remain elevated: Watch for an increase in project cancellations, particularly in the data center sector, and a rise in M&A activity as developers with secured equipment become attractive acquisition targets. This could validate the “phantom megawatt” theory, where 30-50% of announced data center capacity fails to materialize.
• If government incentives accelerate domestic manufacturing: Monitor announcements for new factory groundbreakings in the U.S. spurred by the DPA and other incentives. The commissioning and ramp-up of these facilities will be a key milestone for future supply availability post-2027.
• If hyperscalers take control: Track partnership announcements between data center operators and OEMs. A trend towards co-investment in manufacturing lines or exclusive long-term supply agreements would signal a fragmentation of the market, where large players secure their supply at the expense of smaller developers.
