Expansion of both AC and DC capacity continues in order to match generation to consumption demands while minimizing transmission losses.
Since 2004, electricity consumption in China has been growing at an unprecedented rate due to the rapid growth of industrial sectors.
Since then, China has very aggressively invested in electricity supply in order to fulfil the demand from industries and hence secure economic growth.
In Russia, construction work on a 2400 km long bipolar ±750 kV DC line, the HVDC Ekibastuz–Centre started in 1978 but it was never finished.
[12] Implementation of the UHV grid enables the construction of newer, cleaner, more efficient power generation plants far from population centers.
[14] The UHV grid will aid China's plan of electrification and decarbonization,[15] and enable integration of renewable energy by removing the transmission bottleneck that is currently limiting expansions in wind and solar generation capacity whilst further developing the market for long-range electric vehicles in China.
