Over the last 15 years, the Commercial and Industrial (C&I) Distribution Transformers Committee has driven market transformation and catalyzed development of energy efficient distribution transformers. Their progress became evident in 2007, when the federal minimum standard was first increased to match the CEE Tier I specification. Now, as the market share of energy efficient products continues to grow, another increase to the federal minimum standard is scheduled for January 1, 2016. In preparation for the coming federal minimum standard increase, CEE launched campaign to increase participation in the CEE C&I Distribution Transformers Initiative to help members capture the greatest amount of energy savings possible.Dry type C&I transformer in office utility closet.

The CEE campaign to help members realize those savings has met with notable success. From 2012 to 2014, the number of administrators participating in the initiative nearly doubled from six to eleven. At the same time, the number of manufacturers offering products that met the CEE Tier 1 specification more than doubled. During that year,the number of distribution transformer products that met the CEE Tier 1 specification nearly doubled as well. For example, the Distribution Transformers qualifying products list added over 150 new that meet the CEE Tier 1 specification.

Distribution transformers meeting the CEE specification achieve steady energy savings of at least 30 percent less total losses than standard efficiency equipment over their 35-year useful life. While the majority of distribution transformers on the market today are relatively efficient, converting more than 97 percent of input power to output power, even a small increase in efficiency can yield significant gains when the product runs 24 hours a day, 365 days a year, for over 30 years.

Once the new federal minimum standard takes effect in 2016, and the new standard is increased to the current CEE Tier I specification, the CEE Distribution Transformers qualifying product list will no longer be maintained. Those manufacturers who produce energy efficient distribution transformer models before that date are prepared for the new federal minimum standard, and customers who purchase energy efficient models get a head start on energy savings.

About CEE
CEE is an award-winning consortium of efficiency program administrators from the United States and Canada. Members work to unify program approaches across jurisdictions to increase the success of efficiency in markets. By joining forces at CEE, individual electric and gas efficiency programs are able to partner not only with each other, but also with other industries, trade associations, and government agencies. Working together, administrators leverage the effect of their ratepayer funding, exchange information on successful practices and, by doing so, achieve greater energy efficiency for the public good.
