"Large Power Transformers and the U.S. Electric Grid" Report (June 2012)

The Office of Electricity Delivery and Energy Reliability has released the "Large Power Transformers and the U.S. Electric Grid" report, an assessment of the procurement and supply environment of large power transformers (LPTs). The report examines the characteristics and procurement of LPTs, including key raw materials and transportation; historical trends and future demands; global and domestic LPT suppliers; and potential issues in the global sourcing of LPTs.

LPTs have long been a major concern for the U.S. electric power sector. Key industry sources — including the Energy Sector Specific Plan, the National Infrastructure Advisory Council's A Framework for Establishing Critical Infrastructure Resilience Goals and the North American Electric Reliability Corporation's Critical Infrastructure Strategic Roadmap — have identified the limited availability of spare LPTs as a potential issue for critical infrastructure resilience in the United States.
