Local power companies leverage the 920 Project to expand into other regions.

The curtain has fallen on Project 920, and as equity auctions unfold, the traditional power landscape of generation companies is quietly undergoing transformation. Particularly noteworthy is the proactive approach taken by local power companies. Local power groups—represented by Yue Dian Li and Shen Energy—are now embarking on a path of expansion beyond their home regions and are gradually transforming into nationwide power conglomerates. At the outset of this round of power sector reform, the power-generation assets formerly owned by the former State Power Corporation were allocated to the five major power-generation groups. Although this marked a significant step toward separating power generation from grid operations, the power-generation assets assumed by any single group tend to be concentrated within unified geographic regions, inevitably giving rise to the risk of regional monopolies. For power-generation companies themselves, this...

Railway capacity will continue to favor coal transportation this year.

To ensure the supply of coal for power generation during this year’s peak summer demand period, railway capacity will continue to be tilted toward coal transportation this year. Leveraging the newly added capacity resulting from speed increases, we will strengthen transport organization, improve unloading efficiency, and raise the standard of unloading operations. The Ministry of Railways has instructed all relevant units to closely monitor vehicle disassembly and reassembly operations, with stations required to achieve rapid disassembly, quick retrieval, and prompt delivery, thereby accelerating vehicle turnover and effectively implementing measures to prioritize the transportation of coal for power generation. Following the sixth large-scale speed increase and timetable adjustment in the railway system, a batch of new technological equipment—including high-power Harmony-type locomotives and 70-ton heavy-duty freight cars—has been put into operation, significantly boosting coal transportation capacity on certain railway lines.

Equivalent Impedance Study of Harmonics for the ±800kV Xiangjiaba–Shanghai Ultra-High-Voltage Direct-Current Transmission Project

Based on the research findings from the planning of power transmission schemes for hydropower from southwestern China and in combination with relevant foreign studies, ±800 kV DC transmission is technically feasible and well-suited to China’s actual conditions. The boundary conditions for connecting the converter station of the Xiangjiaba–Shanghai ±800 kV ultra-high-voltage DC demonstration project are complex, and the power grid operation modes in the Jinsha River region are diverse. Therefore, it is crucial to reasonably determine equivalent harmonic impedance parameters used in the design of AC filters, which will enable a rational configuration of the AC filter scheme and ensure the optimized design of reactive power compensation and control strategies. Consequently, it is necessary to understand the frequency characteristics of the system impedance as seen from the AC busbars of the converter station into the power system.

The “big cake” of nuclear power is attracting numerous companies to compete for a share.

The situation in which China National Nuclear Corporation and China National Nuclear Power Group dominated the nuclear power sector has come to an end. Traditional power companies, such as China Power Investment Corporation and China Huaneng Group, have also entered the nuclear power development field one after another. A relevant official from the State Science and Technology Commission recently revealed that, in addition to state-owned enterprises being allowed to invest in and develop nuclear power projects, private and foreign investors can also participate—but they won't be permitted to hold controlling stakes. Many Chinese and foreign enterprises have already begun gearing up and preparing to grab a share of the lucrative nuclear power market.
