Testimony by Principal John Morris helped WPS Resources Corporation and Peoples Energy Corporation obtain Federal Energy Regulatory Commission Merger Approval under Section 203 of the Federal Power Act. WPS and Peoples announced plans to merge in July 2006. WPS owns electric generation facilities and natural gas distribution facilities in eastern Wisconsin and Peoples owns natural gas transmission, storage, and distribution facilities in Illinois. Dr. Morris provided studies showing either that the relevant upstream natural gas markets are not highly concentrated or the two companies do not compete in the same market. The Federal Energy Regulatory Commission approved the merger on December 21, 2006 .
