Regional energy assessment refers to the method of compiling a regional energy conservation report in an area where the target task of energy "dual control" can be implemented, analyzing the current situation of energy consumption in the region, proposing the control targets of energy consumption intensity, total amount and total coal consumption in the region within a period of time, and clarifying various energy-saving measures and energy efficiency standards that are compatible with the industrial planning of the region, so as to determine the negative list of regional energy-using enterprises. The regional energy-saving report approved by the review can replace the general energy-saving report of enterprise projects, so as to simplify the administrative examination and approval procedures, serve enterprises and implement energy-saving and consumption-reducing goals and tasks, and carry out in-process and post-event supervision in accordance with the law.
Key analysis and countermeasures of regional energy assessment.
Establish regional energy efficiency standards.
Energy efficiency standards are the normative constraint values of the energy consumption level of enterprises in the region (mainly physical indicators such as unit output or unit area), and it is one of the important contents of the regional energy assessment report to guide enterprises to achieve more advanced energy efficiency levels through the establishment of energy efficiency standards.
Countermeasures: Establish regional energy efficiency standards.
1) Regional energy efficiency standards should first meet the mandatory standards of the state, industry and locality, and be appropriately improved on this basis. According to the type of industry to be introduced into the region, various mandatory and recommended energy efficiency standards are listed in a targeted manner.
2) Refer to the local or nearby industrial energy efficiency guidelines, and put forward specific and actionable requirements for the energy efficiency indicators of various industries in the region.
3) Sort out the energy efficiency of the enterprises that have been introduced in the region, determine the energy efficiency level of the current enterprises, and put forward clear and practical energy efficiency guidance requirements for enterprises that do not meet the requirements of the indicators.
Establish a negative list of regional energy assessments.
The negative list is the threshold for a separate energy-saving review in the region, and the projects outside the negative list are subject to commitment filing management, and the projects in the negative list need to be separately reviewed for energy conservation. Simplifying the approval process for the construction of some enterprises through the establishment of a negative list system is also one of the important significance of establishing a regional energy assessment system.
Countermeasure. 1) The establishment of the negative list should be in line with the development guidance direction of the country, region and industry, as well as the strategic goals of energy conservation, emission reduction and carbon neutrality, and the restricted and prohibited projects should be included in the negative list.
2) For the projects listed in the provincial and municipal "two high" industry catalogs, they should be included in the negative list.
3) For the provincial energy-saving review of the project, should be included in the negative list.
4) For projects that do not conform to the regional development plan and exceed the "dual control" target of regional energy consumption, they should be included in the negative list.
Energy-saving measures.
Energy-saving measures are specific measures taken by enterprises to complete energy-saving goals, which are divided into technical measures and management measures, which are important guarantees for the completion of regional energy-saving goals. The formulation of energy-saving measures is one of the focuses of the regional energy-saving assessment report.
Countermeasure. 1) According to the characteristics and needs of different industries in the region, targeted process energy-saving measures are proposed, mainly including the selection of advanced process solutions, the use of efficient and advanced equipment, the optimization of process parameters, the utilization of waste heat and energy, central cooling and heating, etc.
2) Propose general energy-saving technical measures for enterprises and buildings in the region, including buildings, HVAC, electrical, water supply and drainage, renewable energy utilization, etc., and the relevant measures should reach the advanced level of the country and the industry.
3) All units in the region shall implement various energy-saving management measures, including the construction of industry energy management system, energy statistics and energy measuring instruments and management measures, etc., and continuously improve regional energy efficiency.
Analysis of the difficulties of regional energy assessment and countermeasures.
Energy consumption during the planning period**.
The energy consumption during the regional planning period is an important basis for grasping the future energy consumption of the region and formulating the "dual control" goal of energy consumption. However, due to the large number of regional industry types, the difficulty of obtaining relevant data, the uncertainty of project content and scale, and the future development environment and policies, energy consumption is one of the difficulties in regional planning assessment.
Countermeasure. 1) Strengthen communication with relevant departments and enterprises, and establish effective communication mechanisms and data sharing platforms through means such as symposiums and WeChat groups, to improve the integrity and consistency of data; Improve the quality and reliability of data through data cleaning, cross-validation, data repair, and other methods.
2) Select a variety of appropriate methods and technologies, such as the index unit consumption method, the economic indicator method, the extrapolation method, the analogy method, etc., and conduct a comprehensive comparison and evaluation of a variety of programs to determine reasonable results.
3) Give full consideration to various internal and external influencing factors of the region, such as the level of economic and social development, industrial structure, technological level, energy policy, international and domestic situation, market changes, natural disasters, etc.; Sensitivity analysis, risk analysis and other methods were used to evaluate the influence and uncertainty of influencing factors on the results. Adopt dynamic adjustment, rolling update and other methods to correct the results in a timely manner.
Energy consumption is "dual-control target determination".
The goal of "dual control" of regional energy consumption is to be a binding or expected indicator of the increment and intensity of regional energy consumption on the basis of future energy consumption, which is an important achievement of regional energy conservation assessment and an important basis for formulating a negative list. However, due to the large number of industries, internal and external influencing factors, and large external uncertainties in the region, the determination of the "dual control" goal of energy consumption is also one of the difficulties in regional energy conservation assessment.
Countermeasure. 1) Different industries have their own energy consumption characteristics, and different energy consumption "dual control" targets need to be determined according to different industries.
2) The goal of "dual control" of energy consumption should meet the relevant requirements of the state, local and industry, and play a certain role in guiding energy conservation in combination with the local economic, social and technological development level.
3) The goal of "dual control" of energy consumption should fully consider the current energy efficiency level and future development plan of the introduced enterprises, and should not be divorced from reality, nor should it set too low a threshold.
4) The data should be complete and reliable, and the use of multiple schemes should be reasonable.
