Biopharmaceutical companies require equipment to work continuously when producing products, and continuous energy supply is the basic requirement to achieve this condition.According to the characteristics of production and operation, enterprises should strengthen energy supervision and formulate a reasonable energy management system, which can not only improve production efficiency, but also reduce production costs, so that enterprises can have stronger competitiveness in the market.

1企業電力能源消耗簡介

Brief introduction of enterprise electric energy consumption

生物醫藥產業是一個技術含量高、投資高、收入高、風險高的高科技產業。其高科技不僅體現在產品質量的高標準和嚴格要求上，還體現在對生產設備和生產環境的高要求上。較長的研發周期，高昂的前期成本使其投入大量資金建造符合GMP要求和生物產品標準的清潔工廠和其他公共能源系統設施。

根據我公司年度主要能源消耗統計，總能耗約為兩萬噸標準煤。根據調查、分析，能源系統全年帶負荷運行，能源消耗量隨季節、時間出現周期性變化，夏季、冬季電能消耗大，春季、秋季電能消耗量較小；白天能源消耗大，夜晚能源消耗較小，能源運行存在不平衡的特點。

 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.
