During the "11th Five-Year Plan" period, State Grid Corporation of China invested a total of over 1.2 trillion yuan, and the overall scale of the domestic power grid doubled, marking the entry of China's power grid industry into a period of rapid development. The national power industry investment will reach 6.1 trillion yuan, an increase of 88.3% compared with the "11th Five-Year Plan" period, of which power grid investment accounts for 2.9 trillion yuan, accounting for 48%. During the "13th Five-Year Plan" period, the national power industry investment will reach 7.1 trillion yuan, an increase of 16.4% over the "12th Five-Year Plan" period, of which power grid investment accounts for 3.5 trillion yuan, accounting for 49%.
With the acceleration of China's smart grid construction, the energy metering chip market has entered a period of rapid development. In 2009, due to the release of smart meter standards by State Grid Corporation and the corresponding adjustment of the unified bidding schedule for energy meters, the domestic energy metering chip market size declined slightly. Since the second half of 2010, State Grid Corporation has increased the number of smart meter bids, leading to a significant increase in smart meter sales, thereby driving the rapid growth of domestic energy metering chip demand.
From 2011 to 2015, the domestic energy metering chip market size (by sales volume) achieved a compound annual growth rate of 7.41%. In 2013, the domestic energy metering chip market size surged to 141.47 million units, a year-on-year increase of 30.2%. In 2014, the total bidding volume of smart meters continued to grow, with annual sales of energy metering chips in China reaching 154.68 million units, an increase of 9.34% over 2013. In 2015, annual sales stabilized at 148.77 million units.
At present, China has formed considerable production scale and R&D capabilities, with a cumulative production of 430 million smart meters and a cumulative bidding amount of 88.576 billion yuan. In terms of bidding volume, except for a decline in 2013, the overall trend from 2011 to 2015 showed steady growth, with a compound annual growth rate of 7.41%.
With the gradual expansion of smart meter bidding scale in the past few years, the procurement scale of State Grid Corporation and China Southern Power Grid has grown steadily. In the coming years, influenced by the deepening construction of smart grids in the Chinese market, the rotation of early-stage energy meters, and the increase in energy meter export scale, it is expected that by 2019, the sales volume of energy metering chips in China will reach 184.27 million units.
Under the influence of large-scale smart grid construction and State Grid Corporation's smart meter bidding and procurement, electronic meters continue to grow rapidly, while the market space for electromechanical induction meters shrinks rapidly, and their market is gradually replaced by electronic products. At present, about 90% of the energy meter products produced in China are electronic, and in the future, electronic energy meters will completely replace mechanical energy meters.
At the same time, with the continuous expansion of the power sector, the application fields of three-phase multifunctional energy meters have expanded from basic electricity metering and billing, distribution transformers to substation operation and management, metering for demand-side management of electricity consumption, metering of on-grid electricity from power plants, and billing of exchanged electricity on inter-provincial grid tie lines, etc., and from billing for large industrial users to billing for commercial, non-industrial, and ordinary industrial users. The demand for three-phase products has expanded dramatically, and the three-phase energy meter market has enormous development space.
