Progress Energy: Like Duke in Many Ways

So who is Progress Energy? In many ways, Progress is a lot like Duke Energy.

Whereas Duke Energy is the 2006 combination of Duke and Cinergy, Progress Energy is basically the combination of two major electric companies. In 2000, Carolina Light & Power, which served customers in the Carolinas, merged with Florida Power Corp., which served customers in central and north Florida.

Like Duke, Progress Energy is based in North Carolina – calling Raleigh, N.C. home. Like Duke, it’s a big generator of electricity, with more than 22,000 megawatts of capacity. That compares to Duke’s 35,000 megawatts.

Progress Energy’s territory actually borders Duke on two sides. Most of its territory is east of Duke – bordering the company around the Raleigh/Durham area of North Carolina. But the company also borders Duke on the west – around the Asheville, N.C., area.

You can read more about the comparison between the two companies in this Fact Sheet.

Hard-to-believe, but Progress actually operates four nuclear stations compared to Duke’s three:

 

   

Brunswick - A two-unit plant near Southport, N.C.

 

   

Crystal River - A single-unit plant near Crystal River, Fla.

 

   

Harris - A single-unit plant near New Hill, N.C.

 

   

Robinson - A single-unit plant near Hartsville, S.C.

Like Duke, Progress Energy is a big proponent of economic development in their service territory. In 2009, Site Selection magazine named Progress Energy one of North America’s Top Utilities for Economic Development for the seventh time in the last eight years. Duke Energy has also been a frequent name in the magazine’s Top 10 list.

Both companies have scored well on JD Power customer satisfaction surveys. In 2010, Duke Energy led the South Region in customer satisfaction as far as fewer outages and lower bills. Progress Energy led the South Region in customer satisfaction among the large business segment.

As far as strategy, Progress Energy is moving along a similar track as Duke with regards to renewable energy and energy efficiency. Check out this explanation from Progress’ annual report: “The company is pursuing a balanced strategy for a secure energy future, which includes aggressive energy-efficiency programs, investments in renewable energy technologies and a state-of-the-art electricity system.” Sound familiar?


If you’re over at YouTube, you may have seen most of Duke Energy’s videos. But Progress Energy has its own page, too, with plenty of videos to watch.

But, of course, there are some differences. Unlike Duke, Progress Energy covers quite a bit of coastal territory. The company serves the Atlantic Coast of North Carolina; and part of the Gulf Coast and Atlantic Coast of Florida. Although Duke has suffered with hurricanes Ike and Hugo over the years, Progress Energy has dealt with many more.
