Do UHV transmission projects reduce thermal power generation?
Our results show that UHV transmission projects have significantly reduced thermal power generation and increase renewable energy production and the share of end-use electricity.
How does UHV transmission technology affect energy structure in China?
Impact of UHV transmission technology on energy structure in China is investigated. UHV reduces thermal power generation and boosts renewable energy generation. UHV shifts ground-based coal transportation to power transmission in the sky. Firms' energy consumption behavior changes and shifts to electrified production.
How has UHV transmission changed the energy supply mode?
We find that the opening of UHV transmission projects has changed the energy supply mode from “coal transportation on the ground” to “power transmission in the sky,” which has caused the transformation of the power production structure and promoted the development of renewable energy in resource-rich areas.
What is a UHV transformer?
UHV transformer — typically referring to transformers for AC transmission at kV and above or DC transmission at ±800 kV and above — adjusts voltage levels through electromagnetic induction, enabling efficient transmission and distribution of electrical power.
What is UHV AC & DC transmission?
The development of ultra-high-voltage (UHV) AC and DC power transmission technology, to meet the future large-scale power base for long-distance, has made large-scale delivery possible. In the development of UHV AC transmission at the same time, ultra-high-voltage DC (UHVDC) transmission is also gradually affirmed.
