Energy Efficiency Labeling No. 5 Programme
Policy measure

According to APERC (2010), the Thai government established the Energy Efficiency Labeling No. 5 Programme in 1993 with the objective “to inform consumers that No. 5 labeled appliances/equipment are highly energy efficient and hence will reduce their electricity bills. This will also enhance competition among manufacturers to further improve the energy efficiency of their products”. This programme is applied on a voluntary basis and targets the industrial, commercial and residential sectors.

Project funding derives from various sources, such as GEF grants and the Australian Government (1993–2000); concessional loans from JBIC (OECF) (1994–-2002); reimbursement through the Automatic Electricity Tariff Mechanism (Ft) (1993–2000); and since 2000 through the reimbursement of the Base Tariff which is part of the Electricity Generating Authority of Thailand’s (EGAT) annual budgeting (APERC, 2010).

“Standards, rules and regulations are set for energy-saving equipment, materials and energy management; for example, minimum energy performance standards for 15 types of electrical appliances were announced by the end of 2009” (APERC, 2010).


The Department of Alternative Energy Development and Efficiency (DEDE) is responsible for setting high efficiency labels for a variety of appliances and equipment (Suksod and Suwicharcherdcho, 2006). Moreover, EGAT randomly buys Energy Label No. 5 appliances in the market for a retest every year. This is conducted as part of the efforts to maintain the efficiency standards of the labelled appliances. According to Suksod and Suwicharcherdcho (2006), the “appliances that fail to meet the earned efficiency rating will be stripped off the labels or have their efficiency rating level lowered. They will then be banned from advertizing using the previously earned efficiency rating label.”

No identified challenges.

Suksod and Suwicharcherdcho (2006) report that “the current label is recognizable and according to DEDE management, it has caused the Thai consumer to purchase only those appliances/equipment with the highest “5”rating. The label appears to have transformed the Thai market for labeled products. Since the launch of the first energy efficiency labeling of refrigerators in 1994, the Energy Label No. 5 has been widely recognized as the designation of energy efficiency. It has also sprawled the introduction of many other high efficiency appliances into the market including air-conditioners in 1995. Also in 2001, EGAT along with manufacturers and importers of refrigerators agreed to increase the efficiency rating by 20 percent to ensure a greater energy saving for consumers. As of June 2004, EGAT has labeled 4.931.600 compact fluorescent lamps, 2.700.302 air-conditions, 2.852.440 ballasts, 12.855.749 refrigerators and 11.311.870 electric fans.”
