Arrival of distant power: The impact of ultra-high voltage
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.
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.
Fig. 1 displays the details of China's UHV power transmission lines as of 2022. Notably, the Changji-Guquan ±1100 kV DC transmission line, which spans approximately 3293 km, has the longest transmission distance. This line enables the transfer of coal and wind-generated power from Xinjiang to the East China power grid.
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.
Our results indicate that UHV transmission projects play a crucial role in speeding up power transmission of large-scale clean energy bases and realizing the cross-regional allocation of power resources. This study conducts mechanism analysis from two perspectives: energy production and consumption.
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.
