Washington - For the first quarter of 2011, Pepco made $97 million in capital improvements to its electric system, compared to $65 million for the comparable period in 2010. The increase in investment was primarily due to higher spending for distribution reliability and transmission infrastructure. Also during the first quarter of 2011, Pepco spent $102 million for operations and maintenance of the electric system, compared to $88 million in the first quarter of 2010. The increase in spending was primarily due to emergency restoration costs incurred during severe storms in the first quarter of 2011, higher costs from trimming more trees, and increased spending on corrective and preventive maintenance of the electric system.

"Pepco's investment in infrastructure in the first quarter of this year increased by $32 million versus the same quarter last year, reflecting our commitment to implementing the company's Reliability Enhancement Plan," said Anthony J. Kamerick, Pepco Holdings, Inc. Senior Vice President and Chief Financial Officer. "These funds were associated with new equipment, advanced technology and other assets that will help the system operate more effectively and reliably while offering customers additional tools to help them monitor, control and reduce their energy usage." Kamerick added, "Implementing reliability improvements to Pepco's electric distribution system is Pepco's number one priority."
