West line water transfer and energy storage

How does the west east electricity transmission project affect water resources?

These metrics are used to estimate the effects of the West–East Electricity Transmission project in China on the water resources used in power-generating regions. Results show that the electricity delivered by the project increased from 228 TWh in 2008 to 683 TWh in 2017.

How much virtual water is transmitted eastward?

With the construction of wind and solar energy projects, the growth rate of virtual water was slightly slower than that of the electricity transmitted. In 2017, 2.4 km 3 of virtual water was transmitted eastward. The corresponding virtual water transfer loss throughout the transmission system was approximately 100 million m 3.

Could water losses be a new research focus for power transmission networks?

Minimizing losses in transmission lines and thus reducing the corresponding water losses could be a new research focus for power transmission networks. 5.3. Data uncertainties and limitations There are three main sources of data uncertainty embodied herein.

Can energy storage solve transboundary water and energy conflict in Central Asia?

A solution for transboundary water and energy conflict in Central Asia is proposed. Benefits of energy storage beyond the energy sector are shown. Long duration energy storage is key for high shares of solar PV and wind energy in the region. An open-access, integrated water and energy system model of Central Asia is developed.

How has electricity shifted from Western to eastern regions in 2017?

Compared with 2008, the electricity transmitted in 2017 from western to eastern regions has tripled, and along with the increase in electricity transmission, a significant amount of water was transferred to the eastern regions in the form of virtual water.

How much electricity is transmitted from west to East?

In 2008, the power transmission capacity from West to East reached 63.2 GW and 228.1 TWh of electricity was transmitted from the western regions to the eastern. The north, middle, and south routes transported 86.3, 50.4, and 91.4 TWh of electricity, respectively.
