Overview
Pepco Holdings was a U.S. holding company created in February 2001 to organize the acquisition of Conectiv Power Delivery by Potomac Electric Power Company, commonly known as Pepco. The transaction closed on August 1, 2002, and Pepco and Conectiv became wholly owned subsidiaries of Pepco Holdings. Through these businesses, the company controlled a group of regulated electric utilities and related energy operations serving the Mid-Atlantic United States. The corporate structure reflected earlier consolidation in the regional electricity industry. Conectiv had been formed in 1998 as the holding company for Delmarva Power & Light Company, generally known as Delmarva Power, and Atlantic City Electric Company. These companies had been brought together through the combination of Delmarva Power and Atlantic City Electric. Pepco Holdings subsequently operated the businesses under a portfolio structure rather than presenting every subsidiary under one consumer-facing brand. In 2005, it resumed using the Delmarva Power and Atlantic City Electric names for operations. Conectiv Energy remained the principal surviving Conectiv-branded business and was used for the group's energy-production facilities. The group's regulated utility footprint covered several adjoining Mid-Atlantic markets. Pepco served Washington, D.C., and surrounding Maryland communities. Delmarva Power operated in Delaware and on the Maryland portion of the Delmarva Peninsula, while Atlantic City Electric served southern New Jersey. The portfolio therefore combined urban electricity distribution in the national capital region with utility operations in Delaware, Maryland, and New Jersey. In 2008, Delmarva Power sold its Virginia service territory to A&N Electric Cooperative and Old Dominion Electric Cooperative for $44 million, narrowing the company's presence in Virginia. Pepco Holdings also owned energy-production activities through Conectiv Energy. In April 2010, it sold Conectiv Energy to Calpine Corporation, simplifying the group and leaving the regulated utility businesses as its central operating focus. The company appeared on the 2006 Fortune 500 at number 283 by gross revenue. Its financial and regulatory profile was shaped heavily by utility rate decisions: operating profit doubled in 2011, with approved rate increases in Delaware, Maryland, New Jersey, and Washington, D.C. contributing to the improvement. The company attracted criticism over lobbying, taxation, executive compensation, and its relationship with regulators. Public Campaign criticized its reported lobbying expenditures and tax position during 2008–2010, while the company also restated certain 2005 financial statements in 2006 to correct the accounting for deferred compensation arrangements. Exelon announced an agreement to acquire Pepco Holdings in April 2014. Although the transaction received approval from several federal and state regulators, the District of Columbia Public Service Commission initially rejected it in August 2015. A revised transaction package was approved by the commission on March 23, 2016, and the merger closed the same day. Pepco Holdings consequently ceased to operate as an independent holding company, with its utility businesses becoming part of Exelon's regulated utility portfolio.
History
Pepco Holdings emerged from the restructuring and consolidation of electric utilities in the Mid-Atlantic United States. Conectiv was established in 1998 as a holding company for Delmarva Power & Light Company and Atlantic City Electric Company following the combination of those businesses. Pepco Holdings was incorporated in February 2001 to facilitate Potomac Electric Power Company's acquisition of Conectiv Power Delivery. That acquisition was completed on August 1, 2002, after which Pepco and Conectiv operated as wholly owned subsidiaries of the new holding company. The resulting group brought together several regional utility franchises. Pepco served Washington, D.C., and nearby Maryland suburbs. Delmarva Power served Delaware and the Maryland portion of the Delmarva Peninsula, and Atlantic City Electric served southern New Jersey. The group also retained energy-production operations under the Conectiv Energy name. In 2005, Pepco Holdings restored the Delmarva Power and Atlantic City Electric names for operating activities, leaving Conectiv Energy as the principal remaining Conectiv-branded operation. The company adjusted its portfolio during the late 2000s and early 2010s. In 2008, Delmarva Power sold its Virginia service area to A&N Electric Cooperative and Old Dominion Electric Cooperative. In April 2010, Conectiv Energy was sold to Calpine Corporation. These changes reduced the holding company's non-core and generation-related activities and emphasized its regulated utility subsidiaries. Pepco Holdings was included in the 2006 Fortune 500 at number 283 by gross revenue. Its performance was closely connected to regulatory decisions governing electric rates. The company reported a doubling of operating profit in 2011, which the reference account attributes in part to approved rate increases in Delaware, Maryland, New Jersey, and Washington, D.C. The company also faced public criticism regarding lobbying expenditure, taxes, rebates, and executive compensation. Separately, it restated certain 2005 financial statements in 2006 to correct the accounting treatment of deferred compensation arrangements. Exelon announced a proposed acquisition of Pepco Holdings on April 30, 2014. The transaction encountered opposition from the District of Columbia Public Service Commission, which rejected it in August 2015 even though other regulators had approved it. Exelon and Pepco Holdings pursued revised terms, and the commission approved the transaction on March 23, 2016. The merger was completed on the same date, ending Pepco Holdings' existence as an independent holding company and transferring its utility operations into Exelon's business structure.
