Demand-side Management
Demand Side Management (DSM) has been a key mission assigned to EGAT by the Cabinet on December 3, 1991, and officially launched on September 20, 1993, under the name “Together Conservation” project. This initiative promotes efficient electricity and resource usage across all sectors by encouraging the adoption of high-efficiency electrical appliances and systems. It supports the country’s social expansion and economic growth, which continue to drive rising electricity demand.
Over the past three decades, EGAT has remained committed to reducing energy consumption and carbon dioxide emissions, contributing concretely to climate change mitigation.
| Targets for 2024 | Performance |
| ● Reduction of the use of energy of 1,159 GWh | ● Reduction of the use of energy of 2,355 GWh |
| ● Reduction of greenhouse gas emissions of 627 thousand tCO2 | ● Reduction of greenhouse gas emissions of 1,228 thousand tCO2 |
| ● Redesign of the No.5 Energy Efficiency Label to align with environmentally friendly trends, modern aesthetics, and added value, better meeting the needs of consumers and industry | ● Implementation of the newly designed No.5 Energy Efficiency Label, officially launched on 1 January 2024 |
| ● Expansion of No.5 labeled products to include distribution transformers, solar panels, LED streetlights, and grid-connected solar inverters | ● Implementation of No.5 Energy Efficiency Labeling for four targeted products |
Management
EGAT carries out Demand Side Management by Triple E strategies as follows:
1. Energy Saving Equipment
have played a key role in driving the electrical equipment market by encouraging manufacturers, importers and distributors to produce and supply high-efficiency products. EGAT has developed energy performance standards and implemented the No.5 Energy Efficiency Label, supported by marketing strategies to promote consumer adoption of high-efficiency appliances.
The current label features a 1-5 star rating system, offering consumers more choices for energy-saving products. It also displays the estimated reduction in carbon dioxide emissions over the product’s lifetime, enabling consumers to actively participate in climate change mitigation through informed purchasing decisions. The label includes a symbol indicating environmentally friendly production processes aligned with the circular economy concept, expanding its role from guiding purchasing decisions to supporting sustainable product lifecycle management. Additionally, a QR code provides consumers with access to detailed information on product usage, installation, maintenance and other relevant updates.
These efforts contribute to sustainable energy use and encourage behavioral change among electricity users toward more efficient consumption, reducing unnecessary energy waste. This comprehensive approach, from power generation to end-user consumption, supports tangible public participation in greenhouse gas reduction and aligns with the national goal of achieving carbon neutrality.
2. Energy Saving Building
EGAT offers professional consultancy to support the implementation of energy-saving measures, including the selection of sustainable construction materials and high-efficiency electrical appliances. These services are extended to various sectors, including residential housing, commercial offices, public institutions, educational facilities, retail centers, hospitality venues and healthcare establishments.
3. Energy Saving Habit
EGAT has developed a data collection framework to monitor and verify electricity management performance in alignment with energy conservation measures across residential, business, and industrial sectors. The organization tracks and coordinates data from related projects to support both quantitative and qualitative evaluations. These insights are integrated for post-project analysis to assess cost-effectiveness, with summary reports and recommendations provided. Additionally, EGAT has established and integrated a centralized database and dashboard system to present project progress and key information, enabling stakeholders to make timely and informed decisions.
EGAT promotes knowledge, attitudes, and habits related to electricity conservation among educational institutions at all levels, elementary, secondary, and higher education, as well as among the public in business, industrial, and residential sectors. This is achieved through academic services, activities that encourage efficient energy use and environmental preservation, and the provision of materials and equipment. These efforts aim to foster and advance learning toward systematic energy management.
In 2024, demand side management resulted in energy savings of 2,355 gigawatt-hours and avoided cumulative carbon dioxide emissions throughout the product lifetime, based on the 2021 baseline, amounting to 3.49 million tons of CO₂.

Note
– The No.5 Energy Efficiency Label project has been evaluated across 12 product categories, including refrigerators, air conditioners, electric fans, rice cookers, washing machines, water heaters, LED bulbs (E27 type), LED tubes (T8 type), televisions, commercial display refrigerators, automatic electric water pumps, and twin-tub washing machines.
– The lifetime is accumulated performance according to the lifetime of the project starting from 2021 which is consistent with the timeframe of the Nationally Determined Contributions (NDCs) 2021-2030.
– The greenhouse gas emission factor of the electricity transmission system for the year 2015 was used, as it serves as the baseline year for evaluating progress under the Nationally Determined Contributions (NDCs) framework.

EGAT has outlined future operational plans under the “S – Support Measures Mechanism” strategy to enhance the efficiency of electricity consumption management. These plans include preparations for No.5 labeling of new products such as clothes dryers, chest freezers, and solar-powered LED streetlights. EGAT is also considering expanding the scope of testing standards and energy efficiency criteria for multi-split air conditioners with fan coil units and variable refrigerant flow (VRF) systems with capacities up to 300,000 BTU per hour. Additionally, EGAT aims to promote the development of an e-waste management system for electrical and electronic appliances, in line with the circular economy concept.
