Transformer Manufacturing Association of America

About TMAA

TMAA in the Industry

Our Foundation

Transformers are the heartbeat of the electric grid and serve a vital role in securing both our national security and the transition to new, renewable electric generation.  Transformer Manufacturing Association of America (TMAA) members supply this critical equipment to empower customers in all sectors of the American economy, including electric utilities; renewable energy projects; data centers; U.S. armed forces military bases; emergency first responders; federal, state and local governments; hospitals; emergency services; electrical contractors; industrial manufacturing facilities; railroads; smelters and others.

TMAA is the industry trade organization representing the interests of the domestic transformer manufacturing sector and its customers. The TMAA was forged in the heart of Washington DC’s ongoing battle on trade policies, antidumping and supply chain issues to help craft and implement informed policy decisions positively impacting the domestic transformer manufacturing sector. Our members manufacture power and distribution transformers in the United States or are service suppliers, vendors, utilities, contractors, and others who support the domestic transformer industry. TMAA serves as a resource to its members and to policymakers by convening stakeholders to share policy, scientific, and technological information to foster the advancement of the entire domestic transformer sector.
