Baltimore Gas and Electric Company Working to Restore Electric Service as High Wind Continues Across Central Maryland

Service restored to more than 18,000 customers

BALTIMORE. - Baltimore Gas and Electric Company (BGE), a subsidiary of Constellation Energy (NYSE: CEG), today announced that it is working to restore electric service to customers affected by today’s high wind. This morning the National Weather Service issued a High Wind Warning for the entire Baltimore Metropolitan Area effective until 10 o’clock tonight. Wind gusts may be as high as 60 miles per hour at times. Although restoration work is under way, new outages are likely as the wind continues. Additionally, customers whose service has been restored may experience multiple outages before this event concludes. The vast majority of the outages are being caused by trees and tree limbs falling onto power lines.

“BGE has mobilized its field resources and begun the process of dispatching them to areas experiencing outages,” said Stephen J. Woerner, senior vice president of gas and electric operations and planning for BGE. “We expect high wind to continue across our Central Maryland service area throughout the day and into tomorrow morning. As a result, the total number of customers experiencing outages will likely increase as the day progresses. Additionally, because of the unusually high wind, certain jobs such as those requiring the use of bucket trucks may have to be delayed due to safety concerns. We thank our customers in advance for their patience.”

Many BGE employees are already fully engaged in the restoration process while others remain on stand-by should they be needed to assist with the restoration effort. These dedicated employees are prepared to work through the holiday if it is necessary.

BGE reminds customers that they should never approach downed wires for any reason. Only qualified BGE personnel or contractors are authorized to remove debris from power lines.

Customers should also consider securing lawn furniture and other loose objects outside the home to prevent them from becoming projectiles and causing personal injury or property damage during high wind.

Customers should always be prepared for weather related power outages and can do so in part, by keeping the following items readily available:

Flashlights - not candles

Fresh batteries

Battery operated clock radio

Corded telephone

Fully charged cell phone

Non-perishable foods

Blankets

Customers also should consider filling the fuel tanks of their vehicles in the event a power outage affects service to neighborhood gas stations. For our customers who rely on well water, filling a bathtub with water in advance of severe weather is strongly encouraged. Customers using a generator or space heater should follow manufacturer instructions and be sure to locate generators in well-ventilated areas.

Additionally, customers with special needs such as those who may be elderly, handicapped or dependent on electricity for medical equipment, should have alternate arrangements in place should they experience an extended power outage. Once service restoration begins, BGE’s priorities are public safety issues and critical facilities, such as 911 centers, hospitals and pumping stations.

Then restoration is generally scheduled so that the greatest number of customers can be restored as quickly and as safely as possible. However, in cases of extended power outages, consideration is also given to customers who have been without service for the longest.

In addition to monitoring current and approaching weather conditions which could result in service interruptions, BGE regularly conducts emergency training drills during which all aspects of storm related service restoration are tested. BGE also reviews its Electric Delivery Emergency Response Plan to ensure that storm response procedures are up-to-date and in line with industry standards.
