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.

69% of Electric Utilities Surveyed Separate OT Networks From IT Business Networks

A recent Newton-Evans survey of 55 North American electric utilities finds that companies are even more hesitant than they were in 2016 to combine networks for operational technology with networks used for IT business processes.

Survey participants were asked, “Does your company manage operational technology (OT) protection, control, and automation Ethernet networks separate from your information technology (IT) business process Ethernet networks?” This question is one of several that were asked previously on a 2016 survey of the protective relay marketplace.

In 2019, 69% percent of North American utilities responded that they manage OT networks separately from IT business process Ethernet networks. In 2016, 55% said they manage the networks separately.

94% of North American Electric Utilities Surveyed Use DNP3 for SCADA

Newton Evans Research Company is currently surveying for the upcoming Worldwide Study of the Protective Relay Marketplace: 2019-2022, a four volume market report. Participants in this market study include utility engineers and managers from investor-owned utilities, municipal and provincial utilities, cooperative utilities within the United States and Canada, together with national power systems throughout the world. This year’s study also includes separate surveys of P&C consultants and relay manufacturers.

Interim findings from the survey of North American electric utilities validate earlier Newton Evans observations that DNP3 is more commonly used for SCADA but less so for Substation Automation, controlling actions issued externally to relays, and communications-assisted protection. Almost all North American utilities surveyed indicated the use of DNP3 for SCADA, while 60% said they use it for substation automation. Only 38% indicated the use of DNP3 for communications-assisted protection. Early tabulations have found some increase in deployments of IEC 61850.

The U.S. Submersible Medium Voltage Switchgear Market

In an electric power system, submersible switchgear is the special combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment all enclosed in a “vault-like” casing to prevent flooding damage. Submersible switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is important because it operates in the same way as other forms of switchgear and is directly linked to the reliability of the electricity supply.

A variety of interrupting devices can be used with vaulted submersible switches including fuses, air circuit breaker, oil circuit breaker, vacuum circuit breaker or gas (SF6) circuit breaker.

Newton-Evans has estimated the 2017 U.S. market for submersible switchgear to have been about $140-$155 Million – and growing at about 5% per year, a rate somewhat higher than other MV market segments for electric power infrastructure equipment.

Combined market for testing of T&D equipment was $437 million in 2017

There are a number of equipment reliability, performance and safety tests conducted before T&D equipment is ready for commercial deployment. The list of potential tests that are conducted either by “outside services” firms or by the equipment manufacturer is extensive.

Some of the more common equipment specific tests include: internal arcing faults, short-circuit withstand, load switching, loop switching, capacitive switching, harmonics, temperature rise, impendence testing, partial discharge, dielectric, overload testing and others.

Only a relative handful of test labs are equipped to conduct high power testing for clients. The ability to conduct short circuit testing is largely dependent upon having high power test capabilities. In North America., there are only seven companies that presently operate high power laboratories. Two are commercial labs (DNV GL KEMA Powertest and PowerTech) and five are maintained by equipment manufacturers including Eaton, Littelfuse, Mersen, S&C and Schneider Electric. These manufacturer labs also provide lab testing services to outside manufacturers.
