Progress Energy: CEO Bill Johnson at a Glance

Once the Duke/Progress merger is completed (which we are targeting for late 2011), Progress Energy CEO Bill Johnson will become the CEO of the new company, with Jim Rogers becoming executive chairman.

To find out a little about Johnson, we found this 2007 Raleigh News & Observer article about him. He was named permanent CEO of Progress Energy shortly after this article appeared.

Remember: This article is four years old (and many things have changed since then). Review this to get some flavor for Johnson, his management style and personal background.

Johnson Long the Heir Apparent

By John Murawski

News & Observer, 10-12-2007

For several years, Bill Johnson has been viewed as the chosen one.

Many inside and outside Progress Energy assumed Johnson was being groomed to one day lead the Raleigh-based power company. The star lawyer and college football standout rapidly ascended to the second-highest rank at the Fortune 500 corporation in 2004, passing every test thrown his way.

The speculation could end today. The board of directors of the electric utility is scheduled to hold a special meeting this morning to unseal the company’s succession plan for naming a new chief executive. Johnson, 53, was named acting CEO this week and is temporarily leading the company after the unexpected death of CEO Bob McGehee on a business trip in London.

If he is anointed CEO, Johnson would put his imprint on an organization with 10,600 employees that is responsible for providing electricity to 3.1 million customers in the Carolinas and Florida.

Progress Energy faces strategic challenges ahead, as officials plan how to meet growing energy demand in an era when building power plants is increasingly expensive amid concern over global warming emissions. The company also is a significant philanthropic force and a major player in revitalizing downtown Raleigh.

“There’s no more important company in our community than that one — for a ton of reasons,” said James Kerr II, a member of the N.C. Utilities Commission, the state agency that regulates power rates.

The clues that Johnson had been groomed for the top job are not limited to the Pennsylvania native’s meteoric ascent at Progress Energy. They were on display at management retreats, company meetings and other functions where Johnson chummed with other officials and demonstrated his flair for public speaking.

Raleigh utilities lawyer Edward Finley Jr. said that in private conversation in recent years, as many as 10 Progress Energy officials placed their bets on Johnson as the utility’s next leader. The buzz increased as McGehee’s retirement date neared.

“From within the company, there was a lot of speculation as to who the successor would be,” said Finley, the chairman of the N.C. Utilities Commission. “People work within the company and see the rapport and behavior of the top executives, and they sort of have an intuitive knowledge of what’s going on there.”

The board of directors ratified the executive succession plan only last month with McGehee’s advice. The plan, adopted in anticipation of McGehee’s retirement next year, is confidential and officially unknown to anyone outside the boardroom.


Plan unfolds today

It’s not clear whether the board will name McGehee’s successor today, or take some other action outlined in the succession plan.

Board members have declined to comment or haven’t return phone calls this week.

Johnson has been doing utility work since 1983 after receiving his law degree in 1982. He represented Carolina Power & light Co. as an outside lawyer in the 1980s when the company, later renamed Progress Energy, was involved in contentious proceedings to raise rates to pay for new nuclear plants.

Johnson was recruited to work for the company in 1992 and was promoted eight times, working stints as group president for Energy Delivery and general counsel and secretary for Progress Energy.

Johnson was not available for comment Thursday. If he is picked to run the company, investors will want to know whether he remains committed to licensing new nuclear reactors in North Carolina and Florida, and whether he plans any changes in the company’s business strategy.

Johnson was offensive lineman for Penn State University’s powerhouse football program in the 1970s. Standing 6 feet 4 inches tall, he is a relaxed presence who avoids the scripted speech favored by many executives.

Self-discipline devotee

Johnson’s easygoing demeanor and taste for reggae music and The Grateful Dead should not be mistaken for softness. Johnson’s mantra is self-discipline, which he put into practice recently when he determined to lose 120 pounds. He achieved the goal last year, losing nearly a third of his body weight through diet and exercise, after his doctor warned him that he was obese and headed for heart disease, diabetes or a stroke.

Among the lawyers who opposed Johnson and CP&L more than two decades ago in the rate cases was Robert Gruber, director of the Public Staff, the state consumer advocacy agency on utility rate cases. Gruber and others say that Johnson’s name keeps coming up on everyone’s short list.

“He’s smart, and he’s tough,” Gruber said of Johnson. “I have a lot of respect for him.”
