The new CEO of Arizona Public Service's parent company is set to testify Wednesday in front of the Arizona Corporation Commission. It will be the first time Jeff Guldner has done so in his new job.

Guldner took over at the state’s biggest utility from Don Brandt last month. He’s expected to face questions on issues ranging from political spending to the rate comparison tool that led thousands of customers to be put on plans that were not the least expensive for them.

Dillon Rosenblatt is covering Guldner’s appearance for the Arizona Capitol Times, and he joined The Show for a preview. 

The Show also talked with Arizona Republic columnist Laurie Roberts, who has has five suggestions for ways commissioners can stand up to Arizona Public Service.
