As an evaluation tool for enterprise strategic management and performance management, the Balanced Scorecard plays an important role in the management of enterprises. At the earliest, this evaluation tool was only implemented in enterprises. At present, it has exceeded the enterprise and still It is widely used in government and school systems. In the management assessment, the balanced scorecard can measure economic indicators and non-economic indicators simultaneously and evaluate them on this basis. The reason why it is called "balance" is considered from four aspects: one is finance, the other is customer, the third is internal process, and the fourth is learning and growth. Through these four aspects, the performance level of service is more comprehensive. Evaluation. In many fields, the Balanced Scorecard has been widely used. In the implementation, the theory of the Balanced Scorecard has been continuously deepened. On the basis of the original, an index system for comprehensive performance evaluation of high-tech enterprises has been established. The environmental social performance, external effects, internal effects, and core competencies are evaluated in four dimensions. The Balanced Scorecard reflects the core of the organizational strategy, enabling companies to focus on the corresponding strategic objectives and establish a phased and long-term goal system. In the energy-saving service system, the overall development goal is an important part of the structure of the industry, providing an important direction for the operation of the energy-saving service industry. At present, the service project based on the technological transformation of enterprises is the most important content of the development of power energy conservation services. On the original basis, the four evaluation dimensions of the energy-saving service industry can be further expanded to form comprehensive benefit evaluation, technical service evaluation, internal process evaluation and learning growth evaluation. Specifically, it is embodied as follows:
1 Comprehensive benefit evaluation mainly considers three major economic, social and environmental benefits
The quantitative business performance of an enterprise can be directly reflected from the financial status of the enterprise. The performance of the energy-saving service industry should reflect the comprehensive benefits of society, economy and environment. For customers, power-saving services can help them reduce the economic cost of enterprises, improve the effective utilization of enterprise resources, and increase the efficiency of enterprises, especially for large-scale energy-consuming enterprises, which can improve the electricity consumption of enterprises. In addition, as a whole, it can improve the utilization rate of power resources by the whole society, reduce the emission of energy consumption, and achieve the goal of energy conservation and emission reduction, which is of great significance for the improvement of the ecological environment. Based on this, energy-saving service enterprises and the government have vigorously promoted the implementation of power-saving service projects. The comprehensive benefit evaluation mainly considers three aspects of economy, society and environment. The annual net income is the difference between the revenue and cost of the power-saving service project, which can reflect the income of the power-saving project. After the enterprise conducts energy-saving service projects, the actual saved electricity is also the cost saved. Data reflecting changes in the rate of electricity use in society have a unit GDP power consumption rate and coverage of energy-efficient service applications. The power consumption rate per unit of GDP, that is, the ratio of the difference between the electricity consumption of the whole society and the electricity consumption of the residents and the GDP; the coverage rate of energy-saving service applications, that is, the number of energy-consuming enterprises that use electricity in the region and the energy-consuming enterprises in the region The ratio of the total number, the data in this area reflects the results of the structural transformation of industrial development. Reflecting the comprehensive environmental effects of energy-saving services: the environmental protection effect coefficient, which is the ratio of the sum of the emission reductions of power plants and the energy-saving emission reductions of energy-saving projects to the emission reductions of the whole society.
2 Technical service evaluation includes the effectiveness of both technical implementation and customer cooperation
The business advantage of the enterprise and the relationship with the customer. The product advantage is an important part of the effective connection between the enterprise and the customer. Among all the projects with energy-saving service development, the leading position of energy-saving technology service is of great significance, which directly affects the energy-consuming enterprise. The effect of energy conservation reflects the value pursued by energy-saving service companies and governments. Enterprises also need to realize the benefits through energy-saving services. In the actual operation process of enterprises, the improvement of benefits and the quality of business operations are not necessarily proportional. Therefore, in the management of energy-consuming enterprises, an effective contract energy management mechanism should be formed and This mechanism really works. Technical service evaluation includes the implementation of technology and the cooperation with customers, showing the effectiveness achieved by energy-saving services, and is an evaluation of the efficiency of project energy-saving implementation: the power-saving index, which is the ratio of actual power-saving and avoidable power. The average payback period, which is the time required for an energy-saving service project to repay the original investment from profit, is the average time required for the company to start energy-saving projects. The unit's power saving cost, that is, the cost that can be saved during the implementation of the power-saving project, can be used to estimate the degree of energy-saving technology. The customer pays the integrity, which is mainly reflected in whether the contractual agreement is fulfilled and whether the customer has intentional breach of contract. The realization rate of energy-saving effect is concerned with whether the energy-saving service company has achieved the corresponding goal in standard completion projects, which is of great significance for enterprises to recover investment and profits. The customer's operational status is to assess the size, long-term and short-term production status of the customer's business. The growth of energy enterprise satisfaction, which includes the improvement of cooperation in communication and energy-saving enterprise service awareness.
3 Internal process evaluation includes three aspects: policy support mechanism, investment financing mechanism and operating mechanism.
It is necessary to determine the technical content of energy-saving enterprises in terms of comprehensive benefits, to clarify the overall objectives of the development of energy-saving service industries, and to realize the strategy of enterprise development. The implementation of internal processes of energy-saving service systems is very important: First, it must reflect investment financing and policies. And the environmental factors that make up the monitoring mechanism within the system are how to support the operation of energy-saving services. The second is the improvement measures in the communication and post-control of energy-saving service enterprises and customers. The internal process evaluation includes three mechanisms: policy support, investment financing, and operation. The proportion of local government financial allocation can accurately reflect the effect of the policy on the implementation of the initial development of the energy-saving industry, that is, the ratio of the financial allocation of energy-saving service enterprises and the financial allocation of energy-consuming enterprises. The policy includes subsidies for energy conservation of enterprises and tax reductions for start-ups. On this basis, we must evaluate the implementation of the policy from the perspective of the enterprise. In terms of investment and financing mechanism, the credit rating of the project loan is the ratio of the actual repayment amount of the project to the total loan amount of the project. The development of this proportion can evaluate the credit status of cooperation between energy conservation services and investment and financing institutions. In terms of operating mechanism, the promotion of energy conservation is the ratio of the number of cooperative enterprises and the total number of energy-consuming enterprises in the region. At the beginning of the power-saving service, energy-saving service companies need to strengthen the concept of energy conservation and evoke the corresponding demand to better develop the market.
4 Learning growth evaluation focuses on the cultivation of talents
The investment in learning and growth is an important prerequisite for the development and growth of energy-saving service enterprises and the evolution of the industry. Just because energy-saving services are technology-intensive industries, the level of technological innovation, personnel development, and cultural construction is critical. It balances with the internal operation and management of the enterprise at a certain point, provides the necessary development momentum for energy-saving services, and provides guidance for development goals. This aspect focuses on technological innovation and talent development. The number and proportion of scientific research institutions in the enterprise personnel and the R&D investment of enterprises in energy-saving projects and the number of related patents are important indicators for evaluating the technological innovation strength of enterprises.
In summary, according to the design idea of ​​the balanced scorecard, based on the indicators and systemic, comparability, objectivity and practicability of energy-saving service evaluation, comprehensive benefit evaluation, technical service evaluation, internal process evaluation and learning can be obtained. Based on the four dimensions of growth evaluation, the corresponding specific indicators are compiled to form a comprehensive performance evaluation index system to promote the development of electric energy conservation services. The energy-saving service system has many conditions and advantages for carrying out energy-saving service business. The comprehensive performance evaluation of the power-saving service system is a comprehensive system. The effective performance evaluation is also the power enterprise to fulfill the corresponding social responsibility, complete the scheduled energy-saving assessment indicators, and enrich the country. An effective way to connotate the brand of web services. It is believed that with the continuous improvement of the comprehensive performance evaluation system of the power energy conservation service system, the power grid enterprises will certainly make greater contributions in energy conservation and emission reduction.
leakage breaker can protect against overload and short-circuit. It can be used to protect the line from being overloaded and short-circuited as wellas infrequent changeover of the line in normal situation. It complies with standard of IEC/EN61009-1 and GB16917.1.
China's power energy-saving service enterprises are still in the initial stage of development of the market. Therefore, the supporting environment for enterprises and the framework for business operations are also in their infancy, and they must be standardized and managed to establish and improve the mechanism for enterprise development. To achieve the benign operation of the enterprise, in the formulation of the relevant system of the enterprise, it is necessary to conduct a scientific and comprehensive evaluation of the development of the electric energy-saving service system, reflect the performance of the enterprise operation, and provide a basis for the development of the enterprise.
