It's not quite annual report season, but Exelon Corp. is always one of the first to file its Form 10-K with the Securities and Exchange Commission.
At 434 pages, Exelon's 10-K is required reading for anyone who needs to understand how the Chicago-based power company keeps the lights on.
It's a trove of nuggets such as:
* Exelon had 17,800 employees companywide as of Dec. 31. Of those, 2,300 were employed at its Peco subsidiary. (At the end of 2006, Exelon employed 17,200 people, including 2,100 at Peco.)
* Peco intends to spend $394 million in capital expenditures to add new substations in South Philadelphia and the University City sections as well as to expand substations in Newlinville, Chester County, and Upper Providence, Montgomery County.
* Peco has about 1.6 million electricity customers and 480,000 natural gas customers.
And Exelon expects to spend $731 million for nuclear fuel for the 11 power plants in which owns an interest, such as Limerick in Montgomery County.
