Persistent supply chain delays and extended lead times are reshaping how utilities approach power distribution procurement. In response, organizations are shifting toward more flexible strategies that balance speed, customization and performance.
The Unprecedented Challenge to the Power Grid
Supply chain instability has shifted from a manageable constraint to a structural risk. Lead times for critical electrical distribution equipment, particularly transformers and switchgear, have expanded dramatically.
For example, the data center industry has been experiencing construction delays, leading to disruptions. According to Brennan Church, a director of engineering, procurement and construction for a Miami data center developer, lead times for medium-voltage switchgear can span 40 to 60 weeks.
Experts have seen and reported on the patterns that led to these delays. Research by Wood Mackenzie found a 116% and 41% demand surge on U.S. power and distribution transformers, respectively. This phenomenon arose due to multiple factors, including rising electricity consumption.
The downstream consequences are evident. Queues for renewable energy projects continue to grow as utilities lack the distribution infrastructure to deliver additional capacity. Aging assets remain in service longer than intended, which increases the risk of failure. Restoration timelines for major outages are also extended, especially when replacement equipment is not as readily available.
Utilities are responding by reevaluating procurement frameworks that historically prioritized standardized, off-the-shelf equipment. Currently, that model often fails to deliver the required speed or flexibility.
Shifting from Off-the-Shelf to Build-to-Spec Solutions
One notable shift is the growing reliance on custom power distribution units (PDUs) and build-to-spec assemblies as a strategic alternative.
Custom manufacturing can sometimes access different component supply chains than those serving the mass production market, and equipment engineered specifically for a given application minimizes any costly and time-consuming post-purchase modifications that off-the-shelf units may sometimes need.
Companies like Marway Power Systems emphasize a collaborative engineering process, where its team adjusts design parameters to client requirements, including material parameters. According to the firm, “The best custom PDUs take into consideration the physical environment, electrical environment, and operator environment. Marway specializes in working closely with customers to customize solutions that balance all requirements and considerations.”
Similarly, Segue Manufacturing Services operates as a build-to-spec power distribution units provider, supporting organizations that bring their own engineering designs but require high manufacturing quality. It explains, “Segue engineers can assist your internal team with supplemental, scalable engineering resources wherever you need them...from transitioning products from concept and prototype through pilot production and beyond.”
Custom solutions also address a growing need for retrofit compatibility. As legacy infrastructure varies widely, standardized PDUs often require costly modifications. A custom PDU manufacturer can design equipment that aligns precisely with existing systems, making them easier to install and deploy.
The Rise of the Reconditioned and Rental Market
Reconditioned electrical equipment has moved from a secondary option to a primary procurement strategy. The case rests on speed, sustainability and verified performance.
Lead times for reconditioned units are significantly shorter because they rely on existing equipment inventory instead of new manufacturing cycles. Where a new transformer or switchgear assembly may carry a year-long lead time, a reconditioned unit from a well-stocked provider can reach teams in a fraction of that time.
Sustainability considerations are also influencing procurement decisions. Each year, the world generates two billion metric tons of waste. Extending the life cycle of electrical equipment supports circular-economy principles, reducing the demand for raw materials and lowering the environmental footprint of infrastructure upgrades.
Leading providers have addressed quality concerns. Equipment that has been reconditioned to manufacturer specifications and load-tested under controlled conditions can be as reliable as new production units and may even come with generous warranty terms.
Sunbelt Solomon illustrates how this model is being applied at scale. As a full-service provider of transformers and electrical equipment services, the company offers reconditioned units with a three-year warranty. This approach directly addresses both lead time and reliability concerns.
Customers are well-assured of these benefits. Sunbelt Solomon explains, “Sunbelt Solomon REMAN transformers are the ‘gold standard’ of remanufacturing using industry-leading recondition, design and winding practices. Each REMAN product must meet or exceed the testing standards set by ANSI.”
Evaluating Full-Service Partners Over Single-Product Vendors
The supply chain disruption has exposed a deeper strategic vulnerability, underscoring the importance of full-service providers. Utilities are increasingly prioritizing partners that can deliver equipment alongside engineering expertise and long-term support. This shift recognizes that procurement risk extends beyond acquisition and into installation, integration and operational continuity.
Large-scale providers like Eaton exemplify this model by offering integrated power management systems alongside deep engineering support. Its ability to coordinate across multiple equipment categories is particularly valuable for utility-scale projects with interdependent components.
Eaton also has a special focus on renewable energy, stating, “By capitalizing on the global growth trends of electrification and digitalization, we’re accelerating the planet’s transition to renewable energy and helping to solve the world’s most urgent power management challenges.
Alternatively, Trystar focuses on dependable solutions for temporary and emergency power scenarios. Its role becomes critical during outage response in constrained situations. The company explains, “Designed for durability in tough environments, these transportable distribution units make it easy to control and deliver power where you need it most — from construction sites and outdoor events to shipyards and arenas.”
Sunbelt Solomon operates within this same framework but prioritizes life cycle continuity. As a one-stop shop, it can provide engineering, reconditioned equipment, temporary power solutions and field services in one place.
Frequently Asked Questions

Is reconditioned power distribution equipment as reliable as new equipment?
Yes, reconditioned power distribution is reliable when sourced from a reputable provider. Top-tier reconditioning involves disassembling equipment, replacing worn components and testing to ensure they meet specifications.
What is the difference between a custom PDU and a standard PDU?
A standard PDU is manufactured with fixed configurations and limited adaptability. A custom PDU is engineered to address specific requirements such as voltage, amperage, physical constraints and integration needs, making it ideal for complex or nonstandard applications.
How can a rental solution help with supply chain delays?
Temporary power equipment rentals provide an immediate solution while teams source or manufacture permanent machinery and infrastructure. This approach allows utilities to maintain operations and complete projects without waiting for extended production timelines.
Strategic Sourcing in a Constrained Market
Supply chain volatility has made traditional procurement models less reliable for critical power distribution equipment. Utilities are adapting by integrating custom solutions, reconditioned assets and full-service partnerships into their sourcing strategies. This shift enables faster deployment and improved long-term system performance.
