Main technical content: 1. Applicability. This document applies to natural gas distributed energy units with a heat-to-power ratio of no less than 50%; it is suitable for calculating and assessing the energy utilization efficiency of existing, newly built, or expanded natural gas distributed energy units; and it is applicable to energy efficiency control of new or expanded natural gas distributed energy units within Guangdong Province. After researching and analyzing the main product types in the industry and existing national, industry, and local standards, and considering the development strategy and actual production situation of the industry in our province, comprehensive heat efficiency has been selected as the main energy efficiency indicator. 2. Indicators and grades. The evaluation object is natural gas distributed energy station units. The energy efficiency grade of the units is classified according to comprehensive heat efficiency, divided into Grades I, II, and III. 3. Statistical and calculation methods. The statistical methods specify the statistical scope of comprehensive energy consumption for natural gas distributed energy stations, the basic process flow of the statistical scope, statistical methods, and metering management requirements. When calculating the comprehensive heat efficiency of production enterprises, the input of primary energy, power supply, and heat supply should be converted into standard coal before calculation. The calculation methods specify the calculation methods for the comprehensive heat efficiency of natural gas distributed energy stations and related basic indicators. 4. Grade and result application. For different indicators, the energy efficiency grade of natural gas distributed energy stations is evaluated. The energy efficiency grade indicators are shown in Table 2. It is stipulated that the comprehensive heat efficiency of existing, newly built, or expanded natural gas distributed energy units should not be lowe
