A Look at the U.S. Medium Voltage Electric Power Equipment Services Market

The total MV services market is very large – possibly in excess of $15 billion. This larger view of the MV services market encompasses multiple segments such as field and in-plant equipment maintenance and refurbishment; construction-related services for distribution substations and MV under-grounding activities; training classes for utility/C&I engineering and operations staffs; site analysis and permitting for distribution utilities and renewables projects; and MV equipment testing services, including commercial test labs and field service diagnostics and testing firms. In addition, vegetation management and telecommunications services are both very large power utility-related businesses in their own right, with significant portions of segment revenue obtained from medium-voltage projects, and these topics will be covered in articles later in 2024.

U.S. Medium Voltage Equipment Services
The U.S. MV equipment services market itself is very large (>$4 billion is our estimated minimum market size) in total, comprised of at least three major sub-segments and is served by hundreds of national, regional and local-area electrical equipment service providers.

While much of MV equipment services growth for third party firms seems likely to be in the 3-5% range, there are a few areas that may see larger increases in revenues, including the upper MV ranges of switchgear, along with gas-insulated units and underground equipment. As well, transformer maintenance, repairs and retrofits are commanding more attention and relying on third party services as new transformer prices, product availability and long lead times affect grid reliability.

Numerous MV Maintenance Market Participants
In multiple research studies conducted over several decades, Newton-Evans Research has found more than 275 U.S.-based companies and organizations provide one or more types of MV equipment-related services to electric utilities and to C&I customers. Each of these was earning related revenues of at least $10 million in annual revenue, with about 45-50 firms in the group earning in excess of $20 million annually from the provision of MV-related services. There is a growing group of domestic firms earning in excess of $250 million in MV services revenue. Another large segment of commercial providers offers services in addition to equipment maintenance, repair and refurbishment. These include utility staff training services, equipment testing services and some portion of construction related (design/build) services.

When it comes to MV equipment services, two product categories account for the lion’s share of segment revenue. These are switchgear/circuit breaker and distribution transformer equipment services.  Let’s take a closer look at these.

MV Switchgear Services Revenue Assumptions based on Third Party Service Firm Website Information
Switchgear services (maintenance, repair, refurbishment and re-manufacturing) are often grouped with similar Circuit Breaker services and together account for several hundred million dollars of utility and C&I expenditures. There are national, regional and local area third-party T&D services firms that provide various levels of equipment services for utilities and the C&I communities. Some of the national names prominent in the switchgear services, maintenance and repair/refurbishment market include Shermco, CBS Services and Saber Power Services.

While many services firms are in the “small business” category and earn less than $10 million annually, there are several others that earn in excess of $100 Million from a variety of T&D equipment service offerings.

Distribution and Power Transformers
While Newton-Evans estimates as much as $900 million is spent annually on electric power transformer services and replacement parts, the majority of this amount goes for power transformers. Nonetheless, there are several firms that specialize in service and repairs for pole-top and pad-mount distribution transformers. Among the large firms that service, repair and refurbish transformers of all sizes and offer nationwide services, include companies such as IPS, Sunbelt Solomon, RESA and others. A number of smaller firms specialize in maintenance, repairs for distribution transformers at a regional level, including Northeast Power, UTB Transformers and Valley Transformers, Inc.

Twenty years ago, a Newton-Evans survey found that many utilities did not bother with repairs to, nor did they consider third party maintenance, of pole-mount distribution transformers. Unit replacement was easier and faster than was rework and repair. At that time, manufacturing capacity for pole-mount units was sufficient to meet domestic U.S. demand, and lead-times were quite short, compared with today’s market. Most electric power utilities had been able to procure and store scores or hundreds of spare pole-top units for emergencies or time-based replacement up until the COVID years.

All Other MV Equipment Services: The third arm of MV equipment services we consider to be comprised of “all other” equipment of significant cost – that is, costing multiple thousands of dollars. Based on a small sample utility survey conducted during late 2023, it appears that relatively low-cost equipment including reclosers, sectionalizers, fuse links, distribution line monitors, fault current limiters, surge arresters and MV capacitors were very likely to be replaced rather than repaired.

Our next article on MV Services will focus on construction-related services for distribution substations and MV undergrounding activities; training classes for utility/C&I engineering and operations staffs; site analysis and permitting for distribution utilities and renewables projects; and MV equipment testing services, including commercial test labs and field service diagnostics and testing firms.

A Look at the 2021 T&D Services Market in the United States

Over the past decade, the need for on-site T&D equipment servicing and parts replacement has grown, both for electric utilities and for commercial and industrial customers. While Newton-Evans has studied this portion of the T&D market in a cursory manner over the decades, we have not produced a multi-client study of this important segment of T&D-related spending. Even now, our definition of T&D services is not all-inclusive, as there is significant related expense incurred for equipment testing services (about $450 Million) and even more investment for replacement parts for ancillary equipment like structures, connectors, line tools, et al, accounting for multiple hundreds of millions of dollars.

While much of the cost of T&D equipment services and repairs is grouped as operating expense, we believe there may be some “replacement parts” costs that are likely classified as capital expenditures, especially costly parts for large power transformers and components for HV substation equipment.

The total value of expenditures for T&D equipment-related services and replacement parts in the United States is likely around the $4 Billion level as of 2021, and our estimate for global spending on T&D services is in the $18-20 billion range. These estimates exclude the costs of equipment unit replacement. Together, T&D equipment services, including repairs and replacement parts, accounted for perhaps $3.6 Billion to upwards of $4.2 Billion in 2021. See Figure 1.

Looking at T&D equipment field services, including repairs and maintenance services performed by third parties, our mid-point spending estimate is $1,750 Million. See Figure 2.

Similarly, the spending for replacement parts for HV, MV, LV equipment and for power and distribution transformers is estimated to be in the $2,200 Million range. See Figure 3.

The overall split of spending between utilities and the C&I community is about a four-to-one ratio in our view, with utilities accounting for the bulk of all HV, MV and transformer-related spending, but with the C&I group accounting for substantial portions of LV equipment services and replacement parts, some MV and transformer services, and occasional HV equipment servicing.

The largest portion of spending among the four categories studied for this article (HV, MV and LV equipment, and transformers of all sizes) is for MV equipment services and replacement parts. HV equipment services follow, then comes spending for power transformer services and LV equipment services.

Sizing the Market for Electric Power Grid Modernization In an Era of Pandemic

According to the U.S. Department of Energy’s Energy Information Administration, annual spending on electricity distribution systems by major U.S. utilities continued to increase year-over-year through 2019, with major utilities spending some $57.4 billion on electric distribution in that last pre-pandemic year. More than half of utility distribution spending in 2019 went toward capital investment ($31.4 billion) as utilities worked to replace, upgrade, and extend existing infrastructure. Another $14.6 billion was invested in operations and maintenance (O&M), and $11.5 billion was appropriated for customer expenses, which included advertising, billing, and customer service.

In 2019, much of the $31.4 billion distribution system capital investment (40%) was spent on power lines, both underground (23% of investment) and overhead (17% of investment). Distribution lines are added or expanded to accommodate new neighborhood development or higher electricity flows as sales increase.1
Keep in mind that when spending by municipal electric utilities and electric cooperatives are added to the EIA totals, the amounts reported by EIA actually would increase by about 25-30%, at least in our estimation.  The bulk of this additional non-IOU spending was for distribution expenditures.

We have increased these amounts for 2020 and 2021, if only to account for inflationary pressures on prices of electrical equipment and systems. Thus, our view is that, in 2021, about $60 Billion was spent in total, on electric power distribution activities in the United States. Of this amount, $33 Billion was estimated for capital investment, and about $20 Billion of the total went for distribution equipment and systems.


Fig. 1

Newton-Evans’ recent year studies of U.S. combined utility and industrial/commercial spending for dozens of specific T&D products, equipment types and systems suggest about $22 Billion was invested in about 70 specific T&D equipment types in 2021.2 Note that this estimate includes spending for both transmission and distribution. In fact, the total expenditures for T&D procurements likely exceeded 100 billion dollars. See Figure 2.


Fig. 2

This $22 Billion shown in the above chart excludes additional billions of dollars invested in power lines, underground cables, electric power poles, meters and ancillary equipment as well as customer-related spending, certain substation construction and O&M services.

One recent Newton-Evans’ study of capital investment changes brought on by the COVID pandemic, resulted in an expected drop in CAPEX from 2019 to 2020, followed by stabilization and a moderate increase in spending for some areas in 2021. Some respondents cited this as a “deferral” of investments rather than a cancellation of investments at the time of the study.3 Nonetheless, total capital investment by U.S. electric utilities during the 2020 and 2021 years likely centered around the $130 Billion mark.4

If the nation (and the entire world) can move on from the ongoing pandemic era, to an endemic period, grid modernization investment may recover some of the momentum lost or deferred from the past 24 months. As well, the significance of the passage of the Infrastructure Investment and Jobs Act in November, 2021, cannot be overstated. More than $60 Billion dollars of funding under this new act has been allocated to the energy sector, most of that amount earmarked for modernization of the electric grid.

U.S. Market for Distribution Transformers Standing at $3 Billion, Based on Findings from Recent Newton-Evans Study

7 November, 2019.  Ellicott City, Maryland.  Based on the findings obtained in a recently completed study of the distribution transformer market in the United States, Newton-Evans provides the following information summary.

Distribution Transformer Market Size Estimates

The aggregated U.S. market for three groupings of distribution transformers stood at about $3 Billion in 2018 as seen in the above chart.  The market was segmented by Newton-Evans as shown here to include residential pole and pad mount units; dry type transformers, and small power/large distribution transformers ranging from 1-25 MVAs.

Institutional Barriers to U.S. Market Entry for Distribution Transformers

The third quarter 2019 Newton-Evans study included survey questions for both end-users and suppliers about any institutional barriers they see to potential market entry by non-North American manufacturers.

Among utility respondents, nearly one-half indicated compliance with recently enacted DOE regulations and recommendations for energy efficient distribution transformers as being a key barrier to market entry by foreign-based suppliers (outside of the NAFTA region). One quarter indicated “buy American” programs at their utility was also a deterrent. About 1 in 5 respondents indicated that Underwriters Lab certification was also important, and several respondents had other supporting comments to offer.

Suppliers commented that the enactment of tariffs also served as a deterrent to foreign manufacturers, while one of the largest domestic suppliers of overhead distribution transformers cited the importance of rapid post-storm response times as being a key factor in re-supplying utilities quickly. Another major U.S. transformer manufacturer cited three factors: UL Certificate requirement, DOE Efficiency requirements and “Buy American” initiatives.

Proposed Import Tariffs: A BAD IDEA for the U.S. Electric Power Industry

by Chuck Newton

We all know that the current administration wants to “make America great again,” but using tariffs to prop up our homeland infrastructure is not the right approach to take at this time.

The U.S. electric power industry can ill afford the extra costs that would be incurred with the placement of 10-25% tariffs on iron, steel, and aluminum, which are core building blocks of our nation’s electrical infrastructure with a good percentage of finished electrical apparatus, equipment and ancillary products manufactured with imported steel and aluminum.

Bringing Grid Modernization to the Distribution Transformer

Guest Article by Vince Martinelli

The reliable operation of the North American power grid is testament to the quality of design, planning and execution over multiple generations of utility engineers. As part of this progression, previous grid modernization efforts added high-performance sensing and communications technologies, first to generation and transmission, and eventually to the distribution system. These technologies helped utilities squeeze more capacity and resiliency out of existing assets cost-effectively, reacting to changes driven by load growth and diversification, as well as industry restructuring.

These trends led to broadly deployed “automation” in the medium-voltage (MV) portion of the distribution system. Medium-voltage substations, where high-voltage power is stepped down to MV on its path toward end customers, have seen the greatest degree of automation. Combined with automation at some of the MV devices downstream from the substation, such as reclosers, capacitor banks and line regulators, this provides the ability to measure and control the system with higher fidelity as compared to managing from the transmission layer. Utilities have evaluated technologies, tested specific solutions in trials, validated use cases and financial models, and made prudent investment choices in rolling out MV automation.

History Repeating Itself
A similar “automation” transition is now happening at the low-voltage (LV) level. Driven by higher reliability expectations, growth of rooftop solar PV generation, energy efficiency programs, the emergence of electric vehicles in the transportation mix, and the promise of battery storage for a range of grid-connected applications, new pressure is being placed towards the edge of the grid. It is more acute in some service areas than others, and can be clustered within one utility’s territory – or even within specific feeder circuits. Driven by these trends, the next frontier in grid modernization is at the interface between the MV distribution layer and the LV distribution layer, centered on the humble distribution transformer, as represented in Figure 1.

Fig1
Figure 1. LV Substations provide critical new capabilities for grid modernization.

Similar to the MV automation rollout, LV substation modernization will happen first at acute “pain points,” becoming more widespread as the technology matures and the detailed use cases are developed.

Active LV Substations Solve Multiple Problems
Among the variety of potential applications, local voltage regulation is a clear “pain point” that cannot be addressed at the MV layer alone. Whether for increasing PV hosting capacity at the neighborhood level by countering voltage rise during reverse power flow, or for supporting energy efficiency programs where the goal is to deliver voltage to customers at the lower end of the acceptable ANSI A range, the benefits of adding automation to the distribution transformer – what we refer to as an LV substation – are becoming clear.

Figure 2 shows two examples of LV Substations deployed by U.S. electric utilities. In each case, a standard distribution transformer is paired with a grid automation device providing control with power electronics-based multi-function regulating capabilities, visibility with onboard current and voltage sensors, and automation with processing and memory components and communications capabilities. These regulating functions include voltage regulation in forward and reverse power flow, power factor correction, and harmonics mitigation. The system also reduces voltage sags, swells, and flicker for the customer connected downstream.

These compact, maintenance-free systems take advantage of existing “real estate” on poles and pads, simplifying the easement process and providing an alternative to costly upgrades on the MV system. The flexible communications platform can integrate with SCADA on the MV system and interact with downstream LV devices, such as AMI (“smart meters”) or behind-the-meter resources, such as next-generation smart inverters, EV chargers or energy storage resources.

Fig2
Figure 2. LV Substation implementations for (a) an overhead system and (b) underground plant, featuring coupled integration with a distribution transformer for siting on a standard pad in a residential area. Adding a power electronics-based regulator with integrated sensing, computing, communications and control software brings grid modernization to legacy distribution transformers.

Figure 3 shows voltage data at a particular customer meter over several months without grid automation; then with the voltage regulation from the LV Substation in place. Voltage variability before upgrading the system reflects MV voltage variations, with dips well below ANSI limits, as delivered to the distribution transformer. When the power electronics regulator is activated with an initial setpoint at 240 V, the only variability at the customer is the load-dependent voltage drop on the LV line itself. This particular customer, and neighboring customers behind this LV substation, now receive compliant voltage and superior power quality, independent of the bulk MV system.

Fig3
Figure 3. Customer voltage delivery improvement measured by utility AMI voltage data showing the control provided by power electronics voltage regulation after introducing the automated LV Substation.

Looking Toward the Near Future
The daily news cycle reminds us that the forces putting pressure on the distribution grid are accelerating, driven largely by changes in how customers choose to participate in their energy future. Whether it’s Hawaii mandating a 100% renewables goal; solar power’s levelized cost of energy continuing to plummet; New York’s REV plan; the ongoing retirement of coal-fired power plants; or nationwide deployment of EV charging stations, the trends are clear.

Fortunately, the concept of automated LV Substations – elevating the status of the long-serving distribution transformer – provides a capital-efficient blueprint for a path forward, modeled after the successful rollout of automation in the MV distribution layer. The difference today is that localized pressure points call for localized solutions appropriate for the demands of the LV layer. The evolution of power electronics-based system designs has resulted in compact, reliable and cost-effective options to consider.

Newton-Evans Study Shows Cumulative Shipments Of HV/MV Instrument Transformers During 2013-2016 Will Approach $1.5 Billion

According to a recent study published by Newton-Evans Research, the “Mid-2013 Assessment and Outlook for the North American Market for HV and MV Instrument Transformers,” the manufacturing of HV IT equipment has a high “concentration ratio” of suppliers. MV IT equipment manufacturing is less concentrated, and the market is supplied by several participants.

Of the key North American IT equipment manufacturers, only ABB participates to a significant extent in both the HV and MV segments. ABB is the clear market segment leader in MV IT shipment values, and is growing to become a significant player in the HV IT segment in North America. One competitor did state that in their opinion, most of ABB’s HV IT shipments to U.S. and Canadian customers are still in sub-transmission and lower HV ranges. ITEC believes its own business will grow nicely with planned new HV offerings in the 230kV range.

Overall, the IT sub-industry group of firms is positive regarding the outlook for IT equipment sales as the deployment of substation automation devices, including more relays and additional substation meters, continues to increase. Utility personnel and T&D engineering consultants we talked with also believe that the IT market is growing nicely, thanks to increases in transmission expenditures and the expansion of renewable energy facilities.

New Report from Newton-Evans: Mid-2013 Assessment and Outlook for the North American Market for HV and MV Instrument Transformers

This new study of High Voltage and Medium Voltage Instrument Transformers shines a light on the growing requirement for additional current and voltage transformation equipment in electric power substations as more intelligent electronic devices are installed both in the substation and on the grid. From protective relays to substation meters to additional substation-based intelligent electronic devices, all require a reliable lower voltage, lower current power source to enable device operation.

According to Chuck Newton, “Newton-Evans Research undertook initial research on the topic of high voltage (HV) instrument transformers in mid-2012, then continued earlier this year for a private client study. Now, as follow-on to these efforts, Newton-Evans has extended its efforts into medium voltage (MV) instrument transformers during the second and early third quarters of 2013.”

Following are some key observations based on the HV/MV IT research program described in the report:

• By 2016, the combined HV/MV IT market will likely grow to more than $400 million annually with about $340-$370 million in U.S. expenditures and $50-$65 million spent by Canadian utilities and industry.
• Cumulative shipments of HV/MV instrument transformers within North America during 2013-2016 will approach $1.5 Billion.
• The manufacturing of HV IT equipment has a high “concentration ratio” (CR3) of suppliers.
• MV IT equipment manufacturing is less concentrated, with the medium voltage IT market addressed by several additional participants. (CR8).
• Sub-transmission level IT equipment, if viewed as a separate segment, would reveal additional market segment suppliers identified in the report.
• The spate of acquisitions a few years ago, involving the acquisition of the three leading “independent” HV IT equipment manufacturers (Trench, Ritz and Kuhlman) by Siemens, Alstom Grid and ABB, respectively, foreshadowed then-anticipated growth in this segment of the IT market in North America. Now, this T&D market segment continues to show promise in light of the construction and installation of new substations and quickening pace of grid modernization programs.

Chuck’s Composite (July 2010)

Very Large Power Transformer Industry: Well, wouldn’t you know it, now that EFACEC has opened the first major new transformer plant in the U.S. in decades, there is more to come. First, the leading India-based transformer manufacturer, Crompton-Greaves, has just opened a new large transformer facility in Missouri. Now word is that Hyundai will construct a large power transformer plant in Alabama. Interestingly as well, the GE PROLEC large power transformer business, having recently completed a significant plant expansion in its Monterrey, Mexico facility, has now surpassed the billion dollar level of business in its own right, based on our estimates.

All in all, these are very interesting and important developments that may help drive decisions among North American utility planning staffs to get moving with procurements for a new generation of “smarter” large power transformers to replace the aging fleet of some 50,000 large power transformers now more than 25 years old, and with a good percentage approaching 40 years of service.

Possible Acquisitions: Rumors have reached Newton-Evans about potential acquisition discussions between two giants (one a mega-giant) in the North American electric power T&D equipment and grid automation business. Could be a lot of industry excitement if this actually develops beyond the “whispers” heard recently.
