This paper describes performance measurements on the dewar, coil, and cryogenic system for the 30-MJ superconducting magnetic energy storage (SMES) unit that has recently been tested at a Bonneville Power Administration substation in Tacoma, Washington. The cryostat, the world's largest fiber-reinforced plastic, open-mouthed dewar, boils off 12 l/h in accordance with previous calculations. Cyclic losses in the coil, 54 W for +-8.4-MW modulation at 1 Hz, are approximately 50% greater than calculated. Refrigerator capacity is adequate to handle the heat produced by the average modulation demand on the coil.
