Work reported is on the development of a 30 MJ superconducting magnetic energy storage (SMES) unit, its installation at the Bonneville Power Administration (BPA) Tacoma Substation, and the preliminary site tests in preparation for its use to stabilize power oscillations on the BPA Pacific AC Inertie. The seismic mounting of the 30 MJ superconducting coil to the dewar lid was completed. The manufacture and testing of the nonconducting dewar were completed. The 5 kV vapor cooled leads were assembled and tested. The refrigerator was placed in operation at the Tacoma Substation and tested by making liquid helium in a 500 l dewar. The refrigerator was connected to the coil dewar and is now used for cooling the 30 MJ coil and dewar with extended purification of the circulating helium to remove contaminants. All equipment was shipped and installed at the BPA Tacoma Substation. Assembly of the 30 MJ coil into the nonconducting dewar was done at the BPA Covington facility and transported to the Tacoma Substation. Substation preparation was completed by 11-1-82. BPA, at considerable expense, did an excellent job preparing the site and assisting with the SMES unit installation. All equipment is in place and operable except for components of the computer control and for full refrigeration of the 30 MJ coil. The converter was tested with the output shorted with the input transformers connected to the 13.8 kV. A new schedule for the SMES operation was established.
