New technologies, including capacitor battery technology, lithium titanate oxide, nickel-iron, and solar thermal, are swelling the pipeline of advanced energy storage projects.

In the context of the smart grid, distribution automation (DA) encompasses a family of technologies, including controls, circuit breakers, reclosers, switches, capacitors, line sensors, voltage regulators, communications, and associated management software, that helps operate the grid with more efficiency and reliability.  Annual utility spending will exceed $10 billion in the coming years, and the market for DA is diverse, dynamic and growing.

Promoted by key projects including large-scale long-distance power transmission, ultra-high voltage grid construction, power grid construction in new rural areas and railway electrification reconstruction, the power transmission and distribution and control equipment industry of China achieved rapid development in 2009, with the annual sales revenue and total profit of RMB 656.19 billion and RMB 49.13 billion, a YoY rise of 15.7% and 19.5% respectively. Boosted by the fast growth of power transmission & distribution and control equipment industry, five sub-sectors mounted up vigorously in 2009. In particular, capacitor and corollary equipment sub-sectors showed the most rapid growth, with the prime operating revenue and total profit increasing by 28.3% and 63.3% respectively from a year earlier. This can be ascribed to the following three factors: firstly, China has made much progress in the development of ultra-high voltage and extra-high voltage technologies; secondly, it is the period from 2009 to 2010 that the ultra-high voltage demonstration projects in China have been constructed in succession, characterizing huge investment; thirdly, China has actively promoted the concept of energy conservation and emission reduction and paid increasing attention to voltage quality, safety and electricity saving, etc.
