Paul J. Bonavia, chairman and CEO of UNS Energy Corp. since 2009, will retire as CEO on May 2 and take a new role as executive board chair of the company, the parent company of Tucson Electric Power Co. announced.
The 37-acre, 5-megawatt photovoltaic array will supply power to customers of UniSource Energy Services. The system, expected to provide enough power to supply about 1,500 homes, is expected to be turned on in the first quarter of 2014.
UniSource Energy Services, a subsidiary of Tucson-based UNS Energy Corp. that provides electric service to about 91,000 customers in Santa Cruz and Mohave counties, has filed a request with state regulators to raise its rates 4.4 percent.
TEP said it has spent up to $500 million on system reliability improvements, new solar generating capacity - such as this solar array at the Solar Zone at the University of Arizona Science and Technology Park - and environmental mandates since 2006.
