In the context of the power industry's development, the market potential for low-voltage circuit breakers is closely tied to infrastructure expansion and energy demand. In 2011, China added 90.41 million kilowatts of new power generation capacity, marking the sixth consecutive year exceeding 90 million kilowatts. This included 12.25 million kilowatts of hydropower, 58.86 million kilowatts of thermal power (with 52.02 million kilowatts from coal-fired units over 300,000 kW, representing 95.3% of coal-fired additions and 88.4% of thermal power), 1.75 million kilowatts of nuclear power, 15.85 million kilowatts of wind power, and 1.69 million kilowatts of solar power, which had entered large-scale production. By year-end, total national power generation capacity reached 1.056 billion kilowatts, including 231 million kilowatts of hydropower (with 13.63 million kilowatts of pumped storage), 765 million kilowatts of thermal power, 12.57 million kilowatts of nuclear power, 45.50 million kilowatts of wind power, and 2.14 million kilowatts of solar power.
By the end of 2011, non-fossil energy sources such as hydropower, nuclear, wind, and solar accounted for 290 million kilowatts, or 27.5% of total capacity, up 0.9 percentage points from the previous year. While the overall power generation growth rate was 2.5 percentage points lower than the capacity growth rate, thermal power equipment growth lagged by 6.2 percentage points, indicating slower installation growth in this sector. This has increased pressure on maintaining grid stability. The trend of power generation moving westward became more evident, with the western region seeing a 14.5% increase in installed capacity, compared to 7.8% in the northeast, 7.3% in central, and 6.4% in eastern regions. The eastern and central regions saw slower growth, leading to tighter supply-demand conditions due to limited grid resource allocation.
During the 12th Five-Year Plan (2012–2016), new power generation capacity was expected to exceed 500 million kilowatts. By the end of the plan, annual hydropower generation was projected to reach 900 billion kWh, equivalent to 300 million tons of standard coal, while wind power would reach 190 billion kWh, equivalent to 60 million tons of standard coal. Solar energy utilization, including both power generation and water heaters, was expected to be equivalent to 50 million tons of standard coal. China’s annual power generation was projected to increase by 66 to 77 billion kWh.
In 2011, the Chinese low-voltage circuit breaker market was valued at 40 billion yuan. With continued growth in power generation and downstream industries, demand for low-voltage circuit breakers is expected to rise, driving market expansion. By 2016, the market size was anticipated to approach 80 billion yuan.
From the late 20th century to the early 21st century, global companies introduced advanced ACBs and MCCBs, continuously improving and expanding their product lines. Siemens, for example, developed intelligent low-voltage electrical systems that integrate power distribution monitoring and building automation. Mitsubishi’s MDU series circuit breakers enable direct integration into energy monitoring networks.
Low-voltage electrical appliances are essential across various industries and are closely linked to societal fixed investment trends. China’s low-voltage electrical industry experienced rapid growth, with an annual growth rate of 10–15%. Market demand is influenced by power, industrial, real estate, and telecom sectors. Future development opportunities include demand structure shifts and international market potential.
During the 12th Five-Year Plan, smart grid construction and technological advancements led to the emergence of intelligent, modular, and communicable low-voltage products. Smart grid investments were expected to reach nearly 2 trillion yuan, with rural power grid upgrades creating new opportunities for the industry. Continued government support and infrastructure investment will sustain stable growth, although competition will intensify.
As smart grid research expands globally, low-voltage devices are evolving toward smarter, more connected solutions. These components play a crucial role in building a reliable, efficient, and safe smart grid. Intelligent circuit breakers and other key elements are becoming industry standards. As multinational companies expand in China and domestic strategies evolve, the low-voltage electrical industry will face significant restructuring and transformation. With smart grid development, high-end and mid-range low-voltage products will align with smart grid needs, forming a new growth area for the sector.
