“…Some of this authority has gradually been relegated to provincial governments over the past few years in an effort to attract investment in large-scale projects and strengthen the role of provincial government in supervising projects during their construction phase (Chen et al, 2019). The significant conflicts of interest and lack of effective coordination among various public agencies across different levels of government have been identified by some studies as one of the key reasons for the slower-than-expected progress of several large ultra-high voltage direct current (UHVDC) transmission projects (Cui et al, 2020;Li, 2014;Liu et al, 2018;Su, 2019), which form the backbone of the southern corridor of the West-East Electricity Transfer Project, aimed at exporting hydropower from Yunnan to Guangdong (Liu et al, 2019).…”

Explaining the slow progress of coal phase-out: The case of Guangdong-Hong Kong-Macao Greater Bay Region

Prompted by the urgency of climate change, this paper analyses the impediments for coal phase-out, by using the Greater Bay Region in China as a case study. Rather than factors specific to coal production, transport and consumption (e.g., subsidies, and vested interests), as suggested by existing literature, the analysis of this paper demonstrates that coal phase-out in the region has encountered a range of market (e.g., high gas price), infrastructure (such as, inadequate network), and regulatory (e.g., prolonged project approval) impediments; these impediments have hindered the effective deployment of alternative energy sources, raising concern about coal phase-out and its crippling impacts on the security of energy supply.Redressing these impediments is therefore a key priority for promoting a smooth coal phaseout in the region. This requires a mix of policies addressing two dimensions: 1) those aimed at squeezing out coal from the energy-mix to create room for alternative low-carbon energy sources; and 2) those aimed at supporting the uptake of these sources. Implementing these policies is however a challenging task as it relies on close-centre-local, and inter-and intraregional cooperation, especially in a resource-poor region with a disperse energy endowment.Achieving this is difficult because the energy policy process of the country has long been characterised by fragmented authority and territorial administrative divisions with a proclivity for local governments to work in isolation from each other.

“…Although incorporating clean energy into the power grid benefits the development of green power as well as energy conservation and emission reduction, substantial electricity curtailment exists. It was reported that the hydropower curtailment for Yunnan Province in 2017 was up to 28.7 billion kWh [30,31]. In accordance with the power regime revolution of the Develop-the-west Strategy in China, the power generated in western areas has been increasingly transmitted into eastern areas.…”

Electricity transmission in a grid-connected system provides an effective solution to promoting clean energy accommodation. However, with arbitrary determination in current operation models, the clean energy utilization ratio (CEUR) is not satisfactory largely due to the lack of electricity curtailment (the electricity equivalent of clean energy curtailment) cost-dependent optimization. In this study, a curtailment cost-dependent multi-objective operation (CCMO) model was proposed to complementarily operate a grid-connected hybrid energy system, identify optimal CEUR, and thus maximally reduce electricity curtailment. The CCMO model centers on coupling the punishment cost of electricity curtailment with the multi-objective function defined as the total cost of each grid component. The CCMO model was solved to derive the optimal equilibrium solution determined based on multiple non-dominated solutions. A grid-connected hybrid energy system including the Yunnan, Guangdong, and Guangxi Power Grids was used to test the model performance. The results showed that the CCMO model’s CEUR was up to 100% at hourly scale and 96.9% on daily average, which were both significantly higher than those in the current operation models. Furthermore, the CCMO’s optimal equilibrium solution, i.e., respective minimum total cost of each grid component, can also identify optimal transmission schemes of the daily channel utilization to make the peak utilization hours largest.

“…Inaccessible regions still have no choice other than the conventional electricity grid. 6 To deal with the major problems of utilizing renewable energy, power-to-gas technology which enables the storage of renewable energy in the form of chemical energy has been emerging as a powerful solution. 7 With surplus electricity that renewable energy produces excessively over the demand, hydrogen (H 2 ) can be produced by electrolysis.…”
