September 1, 2011 Issue

 

A Note from Ron and Steve

The Design Phase kick-off meeting, which brought together 165 individuals from Exelon and Constellation, ended yesterday afternoon after a productive day-long session. Just a few days earlier, Hurricane Irene caused widespread, extensive damage throughout both BGE’s and PECO’s service territories. Thousands of utility employees, assisted by outside crews, continue to work around-the-clock to safely and efficiently restore customers’ service. The utility personnel involved were released from the integration meeting to attend to this important restoration work.

During the Design Phase kick-off meeting, we had an opportunity to hear from Chris Crane and Mayo Shattuck, and devoted the bulk of our time together to laying out the processes we will follow to create our new organization. The hard work on organizational design has begun, and our goal is to complete all of the organizational design work in three months – a tall order and one that will take a great deal of focus, attention to detail and leadership. We will have an overview of the design process for you in the Sept. 15 issue of IN.

While we know that a lot of important decisions will be made during this time period, and we will communicate what we can, it will be some time before all of our organizations’ structures, leaders, policies and related information will be available. We understand how anxious people are to hear more about this. We greatly appreciate your continued focus on running the businesses safely, efficiently and profitably, and on the mutual respect and collaboration that is already in full force among the integration teams.

On that note, one of the highlights of this issue is a side-by-side look at both Exelon’s and Constellation’s vision and values. We continue to rely on these guiding principles to direct our actions and decisions during the merger integration process. You will be happy to see that our companies already share similar values as we look to create our new company.


Rules of the Road

While Exelon and Constellation work to obtain necessary regulatory approvals and to close the transaction, the companies must operate as entirely separate businesses. Employees must treat one another as competitors in our day-to-day work. This means we cannot directly exchange competitively sensitive information, and must be careful not to do anything that lessens competition between the companies or that would lessen either entity’s ability to compete were the transaction not to close. This is an important and sometimes complicated topic. If you have any questions, please discuss with your supervisor or legal counsel before action is taken.

Feedback

Company History: BGE Then and Now

Baltimore Gas and Electric Company (BGE) has a long and rich history. Founded in 1816, the Gas Light Company of Baltimore was the nation’s first gas utility and one of the earliest electric utilities. Over the past 194 years, the company has grown significantly, and today BGE’s 3,500 employees safely and reliably serve more than 1.2 million electric customers and more than 648,000 gas customers throughout Central Maryland.

BGE was recognized by the Environmental Protection Agency as a 2011 ENERGY STAR® award winner in the Partner of the Year category for its commitment to energy efficiency. BGE also received a $200 million federal stimulus grant to help launch a smart grid program that will allow for two-way communication between customers and BGE. When fully implemented, the program will be one of the most advanced in the nation.

Although BGE looks dramatically different than it did almost two centuries ago, one thing has been constant throughout the years: An unwavering commitment to provide excellent customer service. For more information about BGE, visit www.bge.com.
