Power groups urge the Ministry of Energy to reconsider efficiency standards for distribution transformers
Recently, the three primary electricity trade organizations jointly wrote to the US Department of Energy, strongly suggesting a reassessment of the proposal regarding efficiency standards for distribution transformers. Their main reason for proposing this suggestion is the severe problems in the current global supply chain, which have seriously affected the production and supply of transformers, thereby having a significant impact on the operation of power companies.
The US Department of Energy has proposed a proposal aimed at reducing energy losses in three types of distribution transformers (liquid immersed, low-voltage dry, and medium-voltage dry). However, the tense global supply chain poses severe challenges to the production and supply of transformers. This not only extends the order processing time but also increases the difficulty of producing and supplying transformers that meet the new efficiency standards.
The impact of this situation on power companies cannot be ignored. They usually use medium voltage liquid immersed distribution transformers, while the users of low voltage and medium voltage dry type distribution transformers are mainly commercial and industrial sectors. Although the efficiency of liquid-immersed distribution transformers is currently very high, reaching 99.53% (for three-phase transformers with a rated output of 2500 kVA), improving this efficiency will require more complex design and assembly processes. This will further prolong the already long order processing time and may have a more significant impact on the operation of the power company.
The three major electricity trade organizations believe that improving transformer efficiency is essential, but various difficulties in the actual implementation process need to be considered. They called on the Department of Energy to reconsider its proposal and take appropriate measures to address global supply chain challenges to ensure that the production and supply of distribution transformers are not affected.
In addition, they also suggest that the Ministry of Energy collaborate more closely with power companies, suppliers, and other stakeholders to develop more practical and feasible efficiency standards jointly. This can ensure that the implementation of standards does not have a negative impact on the stability and reliability of the power system while also promoting the sustainable development of the transformer industry.
In summary, the three primary electricity trade organizations urge the Ministry of Energy to reconsider efficiency standards for distribution transformers to address global supply chain challenges and ensure the stability and reliability of the power system. They call for appropriate measures to balance efficiency and supply chain issues to ensure the regular operation of power companies and reliable power supply to users.
