The CEE Commercial and Industrial Transformers Initiative, launched in 1997, promotes the manufacture and sales of high-efficiency distribution transformers. In 1998 the Initiative adopted the NEMA TP-1 standard level for high efficiency, as did the Environmental Protection Agency via the ENERGY STAR Transformers Program. In 2007, U.S. Department of Energy raised federal minimum standards for low-voltage dry type distribution transformers to the NEMA TP-1 level also supported by the CEE Initiative and ENERGY STAR. As a result, EPA suspended the ENERGY STAR Transformers specification effective May 1, 2007. Likewise many CEE members no longer offer incentives for distribution transformers on a prescriptive basis.

In 2010 CEE is considering an update to its high-efficiency transformer specification. Staff is researching the cost-effectiveness of high-efficiency, low-voltage dry type products given current materials costs and market conditions.
