Constellation Energy Reports Strong Second Quarter 2005 Earnings

Continued Momentum in Competitive Supply Businesses and Productivity Gains

BALTIMORE, July 29, 2005 - Constellation Energy (NYSE: CEG) today reported second quarter 2005 earnings excluding special items of $0.66 per share, up 22 percent compared to $0.54 per share excluding special items in the second quarter of 2004. These results exceed the company’s earnings guidance range provided in April 2005 of $0.47 - $0.62 per share. On a GAAP basis, the company’s reported earnings were $0.68 per share in the second quarter of 2005, compared to $0.76 per share during the same quarter last year.

“Constellation Energy’s strong performance in the second quarter reflects the continued execution of a business strategy emphasizing smart growth and increased productivity,” said Mayo A. Shattuck III, chairman, president and chief executive officer of Constellation Energy. “The strong quarter was marked by continued momentum in the company’s competitive supply businesses. Constellation NewEnergy again demonstrated its ability to grow volume and maintain margins, while the wholesale competitive supply operation also delivered strong results and grew the backlog of transactions, providing a solid foundation for future years’ earnings. Once again, Baltimore Gas & Electric had a good quarter and is executing to its plan. BGE continues to be a stable contributor of earnings and cash flow.

“Importantly, we continue to make significant progress toward our 2005 productivity target,” said Shattuck. “Most of the actions required to achieve our calendar year target have been executed, and we are well on our way to achieving our $80 million productivity goal this year. Year-to-date, we

have realized about 80 percent of our goal, largely driven by greater operating efficiencies across our Generation Group, which completed record refueling outages at all three of our nuclear plants. We also completed the sale of the Oleander Power Plant in Cocoa, Fla., further demonstrating our discipline to focus our capital and management talent on strategically relevant markets. Based on our success during the first half of 2005, we reaffirm our guidance range of $3.35 to $3.60 earnings per share.”

The following table summarizes both earnings per share excluding special items and earnings per share reported in accordance with generally accepted accounting principles (GAAP) for the three and six months ended June 30, 2005 and 2004:

Baltimore Gas and Electric (BGE)

BGE reported earnings of $0.13 per share for the second quarter of 2005, consistent with the top of our guidance range provided in April and unchanged from the $0.13 per share earned for the second quarter of 2004.

In April, BGE filed a gas distribution rate case requesting an annual gas revenue increase of $52.7 million. BGE last sought an increase in natural gas delivery rates in 1999, and since that time, the utility has experienced higher operating costs and has made substantial capital investments to keep the quality of customer service high. The company expects a decision from the Public Service Commission of Maryland near year-end.

Merchant Energy

Our merchant energy business earned $0.51 per share, which was in line with the high-end of our $0.38 - $0.53 per share earnings guidance range. These results are above the $0.42 per share excluding special items earned during the second quarter of 2004. The increase resulted primarily from productivity gains and the timing of nuclear refueling outages.

Also in the second quarter, Constellation Energy Commodities Group, the wholesale origination and risk management unit, acquired interests in two natural gas producing properties in separate transactions for a combined $233 million. The properties are located in Texas and Alabama, with proved reserves estimated by third parties to be more than 216 billion cubic feet equivalent. The company estimates 2006 production volume will be 10.5 billion cubic feet equivalent.

“These acquisitions are consistent with our strategy across all commodities of focusing on the physical energy requirements of our customers and managing their exposure to commodity prices and volume variability,” said Thomas V. Brooks, president of Constellation Energy Commodities Group. “Our power model has worked well for us, and we have developed a significant competitive advantage that involves acquiring undifferentiated commodities at the source and managing the physical logistics and risks involved in moving the commodity to the customer, often in the form of a customized transaction that meets specific needs. The skill sets of good valuation on the front end, effective hedging and management of variable quantity and price risks, and structuring around customer needs are directly translatable to gas.”

Earnings Excluding Special Items

Constellation Energy presents earnings excluding special items in addition to its reported earnings per share in accordance with generally accepted accounting principles (reported GAAP EPS). Earnings excluding special items is a non-GAAP financial measure that differs from reported GAAP EPS because it excludes the cumulative effects of changes in accounting principles, discontinued operations, and other special items (which we define as significant items that are not related to our ongoing, underlying business or which distort comparability of results) included in operations. We present earnings excluding special items because we believe that it is appropriate for investors to consider results excluding these items in addition to our results in accordance with GAAP. We believe such a measure provides a picture of our results that is comparable among periods since it excludes the impact of items such as workforce reduction costs, which may recur occasionally, but tend to be irregular as to timing, thereby distorting comparisons between periods. However, investors should note that these non-GAAP measures involve judgments by management (in particular, judgments as to what is or is not classified as a special item). These non-GAAP measures are also used to evaluate management’s performance and for compensation purposes.

Constellation Energy also provides its earnings guidance in terms of earnings excluding special items. Constellation Energy is unable to reconcile its 2005 earnings guidance excluding special items to GAAP earnings per share because we do not predict the future impact of special items due to the difficulty of doing so. The impact of special items could be material to our operating results computed in accordance with GAAP.

SEC Filings

The company plans to file its Form 10-Q for the three months ended June 30, 2005 on or about August 8, 2005.
