UniSource Energy Service signs are at offices of Citizens Arizona Electric and Gas offices, the sale of Citizens assets to UniSource completed.
Most of the Citizens gas and electric employees are now working for UniSource Energy Services, and local customers will see little change in company operations, corporate communications director Art McDonald said.
A 22 percent increase in electric rates and 21 percent increase in gas rates became effective with the close of the sale Monday.
The applications for rate increases began after the summer of 2000, were changed several times and finally approved in July as part of the sale agreement with UniSource Energy Corp.
of Tucson, which was announced in December.
In both cases, Citizens was trying to recover increased wholesale costs for electricity and natural gas.
In the case of electricity, the company was trying to cope with wholesale prices that jumped during the summer of 2000 because of the power crisis in California, which had deregulated its electricity market.
Citizens did not own generating facilities and purchased power for its customers on the wholesale market, all of it from Arizona Public Service.
UniSource will continue that agreement.
Another UniSource subsidiary, Tucson Electric Power, does own generating capacity.
About $150 million in increased wholesale electric costs that was not recovered by Citizens through rate increases was absorbed by Citizens Communications, the Citizens parent company based in Stamford, Conn.
The purchase was completed Monday for $220 million plus operating capital adjustments.
UniSource Energy Services, a new subsidiary of UniSource Energy, has acquired natural gas systems serving 126,000 customers and electric systems serving 77,500 customers in northern and southern Arizona.
