Promoting the Sustainable Development of Power Construction Projects through Stakeholder Participant Mechanisms: An Evolutionary Game Analysis

The sustainable development of power construction projects (PCPs) is of great significance in solving the issue of high carbon emissions in the power industry. However, the profit-seeking nature of stakeholders’ strategic choices and other conflicts have seriously hindered this process. This study constructs a tripartite game evolution model for the government, grid companies and the public, and determines the factors and range of values that affect the behavioral and strategic choices of stakeholders based on the literature analysis method and case study method. Numerical simulations are conducted with the help of MATLAB R2021a software to explore the changes in decision-making behavior of stakeholders and system stabilization strategies in different stages of the industry life cycle and the influencing mechanisms. The results show that in the initial stage, the government lays the foundation for the development of PCPs through policy guidance under the government-led mechanism. As PCPs move into the development stage, stakeholders’ benefits increase, creating a collaborative participation situation. As PCPs mature, the role of market guidance comes to the fore, and the interventionist role of government diminishes to a guardian role. In terms of sensitivity analysis of relevant parameters, low government rewards and penalties are not conducive to the adoption of low-carbon sustainable construction programs by power grid companies. The public influences the sustainable behavior of the government and power grid companies through public opinion. In addition, reasonable cost inputs from all stakeholders are critical to effectively promote the steady growth of PCPs. Based on the results, a sustainable development promotion mechanism for PCPs is constructed based on multiple dimensions, with a view to providing decision-making services for stakeholders and thus contributing to the sustainable development of PCPs.

Research On Quality Performance Evaluation Method of Nuclear Power Programconstruction

Nuclear power project construction adopts the general contracting model, which covers four aspects: design, procurement, construction and commissioning. The evaluation of project quality performance in the construction process affects the quality decision of the project. Project quality performance evaluation is to grasp the key factors affecting the quality in the complex management process, and carry on the quantitative analysis of the construction quality. The analytic hierarchy process (AHP) is a scientific method for quantitative analysis of qualitative problems. This paper puts forward an evaluation method for the quality performance of nuclear engineering projects.

Simulation of Carbon Emission Reduction in Power Construction Projects Using System Dynamics: A Chinese Empirical Study

Power construction projects (PCPs) consume a large amount of energy and contribute significantly to carbon emissions. There is relatively little research on carbon emission reduction in PCPs, especially in predicting carbon emission reduction from a dynamic perspective. After identifying the influencing factors that promote the carbon emission reduction effect of PCPs, this study adopted a dynamic analysis method to elucidate the relationship between the variables. A quantitative carbon emission reduction system for PCPs with 51 variables was established using the system dynamics model, and the system simulation was performed using Vensim PLE software. Finally, a sensitivity analysis was conducted on four key factors: R&D investment, the prefabricated construction level, the scale of using energy-saving material, and the energy efficiency of transmission equipment. The results show that: (1) The reduction in carbon emissions from PCPs continues to increase. (2) R&D investment is the most significant factor for improving the carbon emission reduction in PCPs. (3) The value of the above four influencing factors should be increased within a reasonable range so that the four factors can work better to promote the carbon emission reduction effect of PCPs. This paper creatively proposes a dynamic prediction model for carbon emission reduction in the PCP, and the research results provide the scientific basis for government supervision and enterprise decision-making.

Promoting the Low-Carbon Transition of Power Construction Projects under MRV: An Evolutionary Game Analysis

The actual situation of carbon-emission reduction in China’s power sector has not yet achieved the expected benefits. The rent-seeking behavior of participants in power construction projects (PCPs) hinders the realization of low-carbon benefits. It is necessary to explore the behavioral strategies of the various participants in the low-carbon transition of PCPs. This paper creatively constructs an evolutionary game model of PCPs’ participants from the perspective of MRV (monitoring, reporting, and verification) and introduces the influence of the public to provide a comprehensive analysis of strategic equilibrium points. Through numerical simulations with MATLAB R2021a software, this paper explores the strategic choices of participants in different situations and gives relevant inferences and proofs. The results show that the grid company dominates at the initial stage and promotes participants to regulate behaviors. Under the premise of satisfying the system-stability requirements, setting the growth rate of the grid company’s punishments to 100% can enhance the willingness for strict supervision, while the growth rate of the supervision costs to 200% significantly decreases the probability of strict supervision. With the integration of MRV and PCPs, participants spontaneously fulfill the carbon-emission-reduction tasks. Reasonable control of input costs can effectively avoid the occurrence of rent-seeking behavior. In addition, this paper sets the public-influence growth rate at 200% and finds that the public plays a greater role in driving participants to fulfill responsibilities. Based on the results, a low-carbon transition mechanism for PCPs under the MRV system is proposed by considering several dimensions, which provides suggestions for participants to fulfill carbon-reduction responsibilities.

Risk Control Analysis in Electric Power Engineering Project Management

With the development of social economy, the number and scale of electric power construction projects are increasing. Their contents are changing from "single" in the past to "diversified" at present. And the contents of project management are constantly being improved and updated. The function and structure of the electric power construction project in China are relatively complex, involving many factors. There are certain risks in safety, quality, investment, construction period and operating benefit. How to better solve the problems existing in the actual operation process and how to better manage power companies and improve the efficiency and economy of power company projects are the key issues that need to be considered. In order to ensure the economic and social benefits of electric power projects, improve their engineering quality, the project managers must analyze various possible risk factors in time during the construction of electric power projects, and take effective measures to minimize the risks.

Impact of Island Nuclear Power Project on the Spatial Distribution Pattern of Mariculture: A case Study of Niushan Island, China

Nuclear power generation is being promoted globally as a clean energy source and is one of China’s key tools for addressing carbon peaking and carbon neutrality. The Niushan Island of China was selected as the research area and conducted detailed seasonal surveys at sea to explore the spatial distribution pattern of marine aquaculture around nuclear power project and analyze the potential impact of island nuclear power project construction on major marine aquaculture species. The results showed that, the spatial distribution pattern of mariculture around the Sea Island Nuclear Power Project is closely related to the aquaculture environment and seasonality. The main mariculture activities include Porphyra cultivation, mudflat breeding and ponding aquaculture. The envelope area of suspended sediment greater than 10 mg/L is 13.0565 km2 during the construction of the project, which may have an impact on the Porphyra cultivation. The average half-moon tide 1.0°C temperature rise envelope is 31.30 km2 in summer and 2.64 km2 in winter for the 6×AP1400 nuclear power units. The temperature rise caused by human factors may have an impact on the breeding activities of “Jiluo Sanniu Marine Ranch”.

Dynamic Fusion Simulation Method of Intertemporal Decision Preferences of Large Groups in Weak Relationships

The fusion of large group decision-making preferences is generally based on hard constraints, and the general low-consensus heterogeneous preference interaction situation of weak relationship decision-making under soft constraints has not been investigated. This study puts forward the preference connotation structure and preference attributes of the intertemporal decision-making of weak relationships groups, objective preference comparison standards between individuals, preference interaction neighborhoods between individuals, preference learning adjustment rules, and preference cycle interaction result evaluation connotations. On this basis, this research constructs a multistage and multiple-round intertemporal decision-making preference dynamic fusion theory and a method for weak relationship large groups. The simulation results verify and support the constructed preference fusion theory and method, indicating that a relatively rational interactive learning and adjustment process can improve the group decision-making performance of the key digital technology R&D team for offshore wind power project construction, operation, and maintenance and effectively improve the convergence level, convergence time, comprehensive decision-making benefits, and decision-making cognition. In the increasingly open large group intertemporal decision-making situation, these research viewpoints and conclusions will help to expand the strong relationship hypotheses of preference fusion in previous group decision-making research. The research opinions and conclusions supplement the theory and method of preference interaction fusion under soft constraints in large group decision-making.

Delay Causes and Types in Nigerian Power Construction Projects

Numerous events cause delays to entire power projects’ completion timelines, leading to loss. This paper focuses on revealing the critical delay causes in Nigerian power projects and identifying the delay types such as excusable delay, compensable delay, critical delay, and concurrent delay from the different perspectives of owner and contractor. Based on the survey of the 84 industrial experts in power distribution and transmission projects in Nigeria, this study provides the mean score and rank of 39 delay causes. Among the causes, 14 are identified as critical in the Nigerian power project. The top three critical delay causes are corruption and bureaucracy in government, inadequate fund/budget allocation, and price fluctuation/inflation. Owner and contractor do not show the difference in classifying the 14 delay causes into excusable and compensable delays. However, there was a difference between owner and contractor in categorizing whether a cause is critical or not and concurrent or not. A different viewpoint of types of delay cause can lead to a dispute which may lead to other delays and losses, and thus it is meaningful to understand the types of delay perceived from owner and contractor. Even though the delay cause and types are different depending on an individual project, the results of this study serve as a reference and would be beneficial for the practitioners in the construction industry to help identify the delay causes to manage them effectively.

Technical Points of Water-Draw and Discharge Impact Analysis in Guidelines for Water Resource Assessment of Coastal Nuclear Power Plants

Nowadays, cleaner production is getting more and more attention, and nuclear power has been widely used due to its low energy consumption and lower pollution. Most nuclear power plants in China, including those under construction and constructed ones, are coastal. For a nuclear power plant, however, its large amount of water consumption and high guarantee rate of water quality will have impacts on the regional water-resource allocation in the site area. During the water-discharge process, low-level radioactive wastewater and warm water will be discharged, while medium or even highly radioactive wastewater will be generated in an accident, both of which will affect the environment of the receiving water. In 2016, the Chinese government began to work on the Guidelines for Water Resources Assessment of Coastal Nuclear Power Plant Projects. The compilation work, led mainly by the Ministry of Water Resources, focused on analyzing key technical points of the impacts of water intake, wastewater discharge, and their reduction measures, as well as water-protection measures. In this study, the technical requirements for impact analysis of water-draw, wastewater discharge, and their remedial measures for coastal nuclear power construction projects in different periods were put forward. Lastly, the measures for water conservation, protection, and management were given. All the technical requirements and measures gave a research basis and technical support for the formulation of the guidelines.

Regional coal power overcapacity assessment in China from 2020 to 2025

Since the beginning of 2020, the weak domestic power demand caused by the COVID-19 pandemic and the large-scale advancement of coal power construction projects may have further aggravated the coal power overcapacity in China. Given the new situation, this study collected the data on China’s installed electricity capacity and electricity demand during the 13th Five-Year Plan period. Moreover, a reasonable capacity evaluation model of coal power was established based on the energy and electric power balance to analyze China’s coal power overcapacity in 2019 and determine the reasonable capacity for 2025. The internal reasons of unreasonable energy structure and regional difference of energy structure are systematically discussed. Results show that the overcapacity in 2019 was approximately 170 GW, and the overcapacity situation in North, Northwest, and South China was particularly serious. The reasonable coal power capacity for 2025 under the basic situation is 950 GW, indicating that if all the coal power units under construction and planning are operated, the overcapacity in 2025 will be 300 GW. Sensitivity and comprehensive scenario analyses show that under different scenarios, the upper and lower limits of the reasonable coal power capacity in 2025 are 1083 and 794 GW, respectively. Finally, this paper proposes relevant policy recommendations to cope with China’s serious coal power overcapacity problem.

The economic organization of nuclear power construction projects: Organizational models for production and financing

In order to limit the rise in global average temperature to 1.5 °C above pre-industrial levels, international organizations such as the International Energy Agency (IEA) and the Intergovernmental Panel on Climate Change (IPCC) suggest an increasing role for new nuclear power plants. Their pathways entail a large number of new builds by 2050. Given the projected large-scale deployment of new nuclear reactors, it is therefore essential to analyse the existing organizational models. This paper provides an institutional economic analysis of the organizational models for the production and financing of new nuclear power plants. A particular focus is on private sector involvement and competition. In this regard, the paper looks at the division of tasks between state and private actors in financing and production, the governance structures of the companies involved, their market shares, and their degree of vertical integration. The rate of nuclear expansion proposed under the IEA and IPPC scenarios is higher than has ever been achieved in the history of the industry, which has been in decline and contracting since the 1980s. Since the turn of the century, the nuclear sector has been dominated by Russia, while traditional reactor vendors are continually on the brink of bankruptcy and have more or less abandoned reactor exports. Heavy forging capacity for reactor pressure vessels continues to constrain the supply chain, although some new production capacity has been added. Small modular reactors would not alleviate this situation. On the contrary, they would also rely on heavy forges in Russia and Asia. Government support is required for new nuclear power plants (NPPs), be it in liberalized markets or coordinated economies. In liberalized markets support can take the form of federal loans, or power purchase agreements. Countries with regulated markets and a state-owned nuclear industry such as China, Russia or India will probably continue to build NPPs. However, expansion is slowing down even in these countries, while the share of renewables is on the rise.

Causes of Delay in Power Transmission Projects: An Empirical Study

Power transmission (PT) projects are vital for the power sector. However, worldwide PT projects experience delay. There is an urgent need to understand the unique causes of delays in PT projects. This paper presents the first empirical study on causes of delays in PT projects via a comprehensive literature review. Based on this literature review, 63 potential delay factors are identified and divided into ten major groups. These include two new groups of delay attributes, comprising sector-specific factors (SSF) and general factors (GF), where SSF pertains solely to PT projects and GF contributes to minimizing the bias of project participants. A questionnaire survey of 311 PT stakeholders is conducted to determine the overall ranking of the delay factors using the relative importance index. The results indicate that SSF, GF, and external/unavoidable factors are the most critical groups of delay factors, with the top-ranked factors being right of way problems of transmission line (TL), frequent changes in TL routes, and accessibility to the TL tower locations. Finally, recommendations are made to help minimize time overruns in PT projects, as well as in other linear power and non-power construction projects in general.

Causes and Mitigation Strategies of Delay in Power Construction Projects: Gaps between Owners and Contractors in Successful and Unsuccessful Projects

Few studies have verified the different causes of project delays between the owner and contractor perspectives. This article’s goal is to find what the causes of delay are and how to mitigate this delay depending on project performance. Thus, this study investigated 82 owner-side experts and 106 contractor-side experts in Tanzanian power construction projects. In successful projects (less than 10% time delay), the owners and contractors weighted similar causes such as vandalism and permits from authorities. They suggested similar mitigation strategies such as close project supervision, capacity building training, and proper logistics management. While in unsuccessful projects (more than 10% time delay), they exhibited many different responses. In particular, contractors weighted the causes incurred by changes in scope, owner’s poor supervision, delays in approval, failure in planning and designing risk more than contractors. Owners weighted the mitigation strategies such as top management support and timely procurement more than contractors. These findings will help project managers to understand owners’ and contactors’ different concerns and develop better solutions. This study mainly contributes to improving delay management in power construction projects in developing countries.

Huge Dam and Power Construction Projects A Threat to Natural Environment, Alternatives-The Role of Human Resource Development (HRD)

The contribution of HRD to any industry for its growth and success cannot be overstated and hence same is the case with construction sector. Simultaneously the role of HRD in regulating pollutants of huge construction projects impacting environment and biodiversity is laudable. If advices and services of HRD are rightly adopted the negative impact on the same can be minimized. In this paper it is emphasized for setting up of alternatives to huge and mammoth construction projects as well as dam hydropower projects for green. Therefore, river environment can be saved for future generations. The involvement of HRD in this area is inseparable. Thus, it has been suggested to policy makers and concerned governments to go for environment friendly designs with the help of HRD for alignment of various departments and better implementation.

Better late than never, but never late is better: Risk assessment of nuclear power construction projects

This work seeks to evaluate overnight construction costs (OCC) and lead-time escalation of nuclear power construction projects from 1955 to 2016. To this end, a comprehensive database of commercial Light Water Reactors (LWR) was developed and a statistical analysis was conducted. Findings reveal a significant delay in lead-time, especially for the last generation reactors constructed from 2010s, with ¾ of the sample showing significant construction delays. This results in an escalation of capital costs rather than in a decline. Average OCC of newer reactors is 60% higher than the ones implemented in the earlier stages of the nuclear era. This suggests a discontinuity of the learning curve for both OCC and lead-time, which threats the market and financial sustainability of current and future nuclear energy projects. Although this is a general trend, this discontinuity is country specific and, thus, induced by national policies and regulatory frameworks. Therefore, the role of nuclear technology as an alternative to cope with the need for a decarbonisation of the power sector must be better evaluated, taking into account the real cost impacts of nuclear technology implementation.
