生物医****产业是一个技术含量高、投资高、收入高、风险高的高科技产业。其高科技不仅体现在产品质量的高标准和严格要求上，还体现在对生产设备和生产环境的高要求上。较长的研发周期，高昂的前期成本使其投入大量资金建造符合GMP要求和生物产品标准的清洁工厂和其他公共能源系统设施。

根据我公司年度主要能源消耗统计，总能耗约为两万吨标准煤。根据调查、分析，能源系统全年带负荷运行，能源消耗量随季节、时间出现周期性变化，夏季、冬季电能消耗大，春季、秋季电能消耗量较小；白天能源消耗大，夜晚能源消耗较小，能源运行存在不平衡的特点。

 Biomedicine industry is a high-tech industry with high technology content, high investment, high income and high risk. Its high technology is not only reflected in the high standards and strict requirements of product quality, but also reflected in the high requirements of production equipment and production environment. Long r&d cycles and high upfront costs have led to large investments in clean plants and other public energy system facilities that meet GMP requirements and biological product standards.

According to our company's annual main energy consumption statistics, the total energy consumption is about 20,000 tons of standard coal.According to the investigation and analysis, the energy system operates with load all year round, and the energy consumption changes periodically with season and time. In summer and winter, the energy consumption is large, while in spring and autumn, the energy consumption is small.The energy consumption is large in the day and small at night, and the energy operation is unbalanced.
