PFE och energiledningssystem vid Stora Enso Fors AB
Examensarbete för masterexamen
Stora Enso Fors AB consists of a cartonboard mill in Fors and a plant for polyethylene coating in Gästrike-Hammarby. The company participates in a program for increased energy efficiency (PFE) which gives electricity tax reduction if a number of requirements are fulfilled. Participating companies have to implement a standardised energy management system, perform a mapping and analysis of the energy consumption and consider energy efficiency within the purchasing and project management functions. The aim of the report is partly to give recommendations to routines, procedures and the structure of the system and partly to map and analyse the company’s energy consumption. The tasks have been performed with assistance from a project team consisting of representatives from the involved departments within the company. The management system at Stora Enso Fors AB is well developed and the company is certified according to quality, environmental and occupational health standards. The aim with this project has therefore been to fulfil the requirements of the energy management system by improving and expanding the existing management system. In most cases it was possible to modify existing routines and procedures, which means that only a small number of new documents had to be added to the system. The mapping of the former, present and future energy consumption at Fors and Hammarby mills gave a good understanding of how energy is used in different departments and processes. The analysis that followed the energy mapping which mainly focused on electricity and resulted in an identification of important energy aspects and several possible measures to increase the energy efficiency. Purchasing and project management imply more fundamental changes of existing routines and procedures than other areas. Energy costs must be taken into account and life cycle costs have to be calculated. Since the company has inadequate experience in calculation of life cycle costs, templates that are easy to use were constructed.
