The global impact of COVID-19 has been unmatched and staggering, with the ring main unit witnessing a negative demand across all regions amid the pandemic. Based on our analysis, the global market exhibited a decline of -11.2% in 2020 compared to the average year-on-year growth during 2017-2019. The rise in CAGR of this market during the forecast period is attributable to this market's demand and growth, returning to pre-pandemic levels once the epidemic is over.

A notable development in urbanization and multiple smart city initiatives worldwide have led to the development of the demand for RMUs worldwide. Revolution in the electrical and electronic sector has led to urbanization and industrialization, making it necessary to increase the reliability of electric supply. RMU is a type of metal-enclosed switchgear used in safe power distribution. The units are used for circuit control, circuit isolation, and circuit protection. It enhances service quality and reduces operational costs in the long term.

Blockades in Electrical Supply Setups has Harmed Ring Main Unit Market Growth amid COVID-19

The global coronavirus pandemic had a devastating impact on major industry verticals, which suffered significant losses in the operational time of industries, majorly caused by lockdowns that were imposed to reduce the spread of the COVID-19 outbreak.

Consequently, the aforementioned factors have affected the market growth. As the electrical industry affects the market, the weakening faced by the power supply industry due to the reduced power demand from the industrial and commercial sectors impacted the investment in the units. The shutdown of businesses and trades dues to lockdowns reduced the power consumption and further reduced activities of power distribution. Companies and governments postponed their power infrastructure projects. These factors have directly impacted the utilization of the units.

Increasing Adoption of Smart Grids to Augment Market Growth

Notable technological developments have been made in the electrical and electronics sector in the past decade. The increasing reliance on electric power for various appliances and consumer electronics has driven the need for remotely controllable grids. The rise in the demand for smart monitoring and control and digital controlling of power grids has increased the adoption of smart grids. The need for RMUs is observable to assist in these newly set up smart grids. This factor is expected to enhance market opportunities in the forecasted period.

Improvement of Aging Power Infrastructure to Enhance Market Size

According to International Energy Agency's World Energy Investment Report 2020, global spending in transmission reached USD 90 billion in 2019. China saw a high focus on the upgrading of rural power grids and the construction of distribution networks. The U.S. saw growth in investments for the fifth consecutive year due to regulations on improving grid resilience and reliability. Distribution investment in Europe and China remained stable due to lower growth rates for electricity demand. The increasing investment in the improvement of old power infrastructure is anticipated to give rise to smart power systems using switching capabilities like the ring main units.


Rising Industrial Infrastructure to Aid Market Development

Increasing investments in industrial infrastructure are anticipated to hasten the power supply and distribution lines across industries and regions. The increasing industrialization has furthered the setup of new industrial facilities. Industries require complex electrical substations to facilitate their power requirements and avoid accidents due to overloading. Switching equipment like the RMU is necessary to maintain voltage fluctuations. It has become vital to warrant the safe operation of electric supplies due to increased dependence on electrical machinery in industries. Hence, growing investments in industrial infrastructure propel the market growth during the forecast period.

Growing Renewable Energy Demand to Drive Market Growth

The growing conscience for the environment amongst consumers and increased focus on reducing carbon emissions will drive the generation of renewable energy. The development of the renewable energy industry has directed governments to establish power plants to produce power from various renewable resources. The rising dependence on renewable energy resources for power generation can also be accredited to the lower capital requirement than oil and gas.

According to the IRENA’s (International Renewable Energy Agency) Projected Costs of Generating Electricity 2020, the Levelized Cost of Electricity Generation (LCOE) using various energy sources of different world regions was studied. It was found that wind energy costs the least, whereas electricity generation from coal costs the most. The increased investment in renewable energy sources is expected to increase distribution utility, which will require smart switching equipment. This market is expected to grow as a result of these factors.


High Investment Cost Could Hamper Market Growth to Some Extent

RMUs are metal-enclosed switchgear. It includes a protection and metering device. They control circuits, isolate faulty equipment, and protect the circuit from earth faults. Due to their advantages like compact design, smart capabilities, safety and performance, and cost savings, RMUs have high capital costs. The high initial prices of RMUs could also be accredited to the lower economies of scale. The high initial investment adversely affects the market growth rate.
