Thailand Thailand develops Factory Energy Code

FEC legislation will be enforced by 2030

On December 2, the Department of Industrial Works (DIW), Ministry of Industry of Thailand, organized a seminar to update the progress of the project regarding the promotion of energy efficiency in the manufacturing sector at the Golden Tulip Sovereign, Bangkok. The purpose of the project is to develop guidelines for factories to promote energy efficiency in the manufacturing process and introduce a legally binding standard, Factory Energy Code (FEC), by 2030.

In 2018, the Ministry of Energy published “Energy Efficiency Plan 2018 – 2037” or EEP 2018 with the goal of reducing the Energy Intensity (EI) by 30% in 2037 (as compared with 2010). The three key approaches to the target are compulsory requirements, promotion measures, and supporting schemes. The project, which is considered as a part of compulsory requirements, targets new factory and expansion of the existing factory to promote energy-efficient design and develops Process Simulation Model.

Currently, the project is in the feasibility study phase. Comments and opinions from the government sector (Department of Industrial Works, Board of Investment, Thai Industrial Standard Institute, National Innovation Agency, Management System Certification Institute, Department of Public Works and Town & Country Planning, Department of Alternative Energy Development and Efficiency, Office of Natural Resources and Environmental Policy and Planning and Industrial Estate Authority of Thailand) and other relevant organizations (Council of Engineers, Association of Boiler and Pressure Vessel, Air Conditioning Engineering Association of Thailand and private companies) have already been collected.

Following the feasibility study, a draft regulation will be developed by 2026. The project targets to enforce compulsory FEC by 2030.

1. Study the feasibility of the FEC for control factory 3. Prepare regulations to enforce the FEC of the control factory for apply permission to establish or modify 4. FEC Legislation 6. Enforce the FEC in every factory
Study the feasibility of the FEC Legislation
1.1 Data collection for the preparation of energy standards in industrial plants 1. Ministerial Regulation under Energy Conservation Act B.E. 2535 Section 7(7)
2. Ministerial Regulation under Factory Act B.E. 2535 about the process of applying for permission of the new factory
1.2 Design, develop and apply the model of plant energy usage
2. Push and enforce FEC factory control (all relevant departments)
FEC Enforcement
2.1 Establish guidelines for regulating the newly built factory
2.2 Promote the design of factories for energy conservation
2.3 Application for construction / modification of the factory
5. Feasibility study for the preparation of FEC factories outside the control
7. Coaching SEC 8. Apply the regulation to have compulsory energy conservation. Set a goal of reducing energy every 3 years with the SEC for ranks with high energy consumption.
Specific Energy Consumption; SEC
1. Training/Giving knowledge on how to do the SEC for the control factory Define SEC for high-energy factories Set the SEC-Base line
Define Target Setting
Set guidelines and goals of the controlled factories with has high energy usage SEC assessment compare with Baseline

Ministry of Energy, Thailand announced a new Building Energy Code (BEC) on 12 November 2020. The regulation mandates an energy-efficient design for commercial buildings. For more information, visit here.
