UHV Energy Storage Project

What is a UHV project?

A distinguishing feature of UHV projects is their capacity for cross-regional electricity transmission and large-scale renewable energy integration, underscoring their potential to optimize resource allocation.

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.

How does UHV building affect renewable power?

Renewable power has been benefiting from the UHV building effort—but only recently and the positive effects are gradual. Prior to 2018, most of the grid construction was meant for transmitting thermal or hydropower from the west of China, with limited grid connections allocated to renewable power.

What is UHV transmission?

Moreover, UHV transmission projects have transformed power production from “coal transportation on the ground” to “power transmission in the sky,” thereby fostering the development and distribution of renewable energy.
