Constellation Energy Reports Strong Fourth Quarter

and Full Year 2007 Results

— Reaffirms guidance for 2008 at $5.25 to $5.75 per share

— Increases 2009 guidance range to 15 to 20 percent over 2008

— Raises quarterly dividend 10 percent

BALTIMORE, Jan. 30, 2008 - Constellation Energy (NYSE: CEG) today reported full year 2007 adjusted earnings of $4.60 per share, up 27 percent from $3.61 of adjusted earnings per share (EPS) for the full year 2006.  These results were in line with management’s guidance range of $4.45 to $4.65 per share, which was revised upward in October 2007.  Adjusted earnings exclude the impact of special items, discontinued operations, certain economic, non-qualifying hedges and synfuel earnings.  On a GAAP basis, the company earned $4.50 per share in 2007, compared to $5.16 per share earned in 2006, which included an after-tax gain of $1.04 per share from discontinued operations.

For the fourth quarter of 2007, adjusted earnings of $1.48 per share were up 37 percent, compared to $1.08 per share earned in the same period last year.  Reported GAAP earnings of $1.42 per share in the fourth quarter of 2007 compare to $2.22 per share in the fourth quarter of 2006, which included an after-tax gain of 76 cents from discontinued operations.

Constellation Energy reaffirmed earnings guidance for 2008 at $5.25 to $5.75 per share and expects to be in the middle to upper end of the range. Looking forward to 2009, the company expects to grow earnings 15 to 20 percent over projected 2008 earnings, representing an increase over the previously announced greater than 10 percent projected growth over 2008.

“2007 marked yet another outstanding year for our company as we grew adjusted earnings by 27 percent,” said Mayo A. Shattuck III, chairman, president and chief executive officer of Constellation Energy. “Our success in driving strong earnings continues to translate into significant total return for Constellation Energy shareholders. Considering both stock price appreciation and dividends, Constellation Energy delivered total shareholder return of 52 percent in 2007, following the 23 percent and 35 percent total shareholder returns realized over the last two years.

“Last year, we made significant progress on several important fronts, including our efforts to assume a leadership role in the potential renaissance of new nuclear generation in the United States,” said Shattuck.  “Along these lines, we formed our UniStar Nuclear Energy joint venture with EDF and continue to move forward with planned new development projects under the UniStar Nuclear Energy banner.  We advanced the expansion of our Merchant capabilities by building the foundation to make significant, multi-year investments in generation to expand capacity and enhance reliability in Maryland, PJM and other markets we serve. Through several strategic acquisitions, we grew our wholesale load-serving business in the regulated Southeast market, added to our upstream gas reserves and expanded the geographic footprint of our retail gas operations in the Midwest market. We also have successfully implemented key components of several programs at Baltimore Gas and Electric (BGE) that provide customers with tools and incentives to better manage their energy usage.

“In coming years, we see clear and substantial earnings growth drivers and believe we are well positioned to deploy capital to pursue strategic market opportunities,” said Shattuck.

Today, Constellation Energy also announced that it has informed the Office of the Attorney General for Maryland that it plans to terminate the litigation standstill agreement, which has been in place with the Attorney General’s office since November 2006. The standstill agreement pertains to $386 million that the company believes was unconstitutionally taken in Maryland Senate Bill 1, which was passed in June 2006 as part of a Special Session of the Maryland General Assembly.

“We have reluctantly concluded that we have no choice but to file a federal court action to enforce our rights under a nearly decade-old settlement, which has been upheld twice by Maryland courts,” said Shattuck. “The recent Maryland Public Service Commission (PSC) interim report on stranded costs and on BGE’s 1999 settlement injected a

destabilizing element of uncertainty into the regulatory climate and energy marketplace in Maryland. We cannot abide by efforts to use hindsight to reverse decisions and agreements that were made nearly a decade ago by multiple parties in full accordance with the law.

“We recognize our responsibilities in Maryland and take pride in playing a constructive role in the state’s energy infrastructure and marketplace,” said Shattuck. “We are planning to undertake a very large capital expenditure program in the years ahead in Maryland and elsewhere. In so far as we are planning to invest in improving reliability of existing plants and expanding capacity in Maryland, we must have confidence in the political and regulatory environment in which we operate.”

The following tables summarize adjusted EPS and EPS reported in accordance with GAAP for the company’s business segments and provide a reconciliation to total company reported earnings.

Baltimore Gas and Electric

BGE reported adjusted earnings of 17 cents per share in the fourth quarter of 2007, down 1 cent per share versus the fourth quarter of 2006.  For full year 2007 results, BGE’s adjusted EPS was 74 cents, down 13 cents, compared to 87 cents per share in 2006.  BGE’s results for the fourth quarter and full year 2007 were negatively impacted by credits to residential customers required by Maryland’s Senate Bill 1 and higher operating costs, partially offset by higher demand response and transmission revenues.

Merchant

On an adjusted basis, the Merchant segment earned $1.27 per share during the fourth quarter of 2007, up 39 cents per share, or 44 percent, from the fourth quarter last year. Compared to the fourth quarter of 2006, the Merchant segment benefited from higher backlog realization and new business in Wholesale Competitive Supply, strong realized margins in our retail power business and the reversal of prior-period mark-to-market losses previously recorded in our retail gas business, the absence of a refueling outage at the R.E. Ginna Nuclear Power Plant that occurred in the fourth quarter of 2006 and lower interest expense.

For the full year of 2007, adjusted earnings for the Merchant segment were $3.77 per share, representing growth of $1.09 per share, or 41 percent, over 2006. Wholesale Competitive Supply benefited from higher backlog realization, partially offset by lower new business following an exceptional year in 2006.  In our Retail Competitive Supply businesses, full year 2007 earnings benefited from higher realized rates in NewEnergy Electric, offset by mark-to-market losses on hedges of accrual positions and higher costs in NewEnergy Gas. Generation benefited from the roll-off of below-market hedges, the impact of the Ginna uprate and fewer planned outage days, partially offset by the end of competitive transition charge collections, inflation and higher operating costs.  Lower net interest expense also contributed favorably.

Dividend Declarations

                Constellation Energy’s board of directors declared a quarterly dividend of 47.75 cents per share on the company’s common stock, equivalent to $1.91 per share annually.  This dividend declaration represents a 10 percent increase over the previous quarterly dividend rate and recognizes the company’s strong financial performance in 2007 and future growth prospects.  Prior to this increase, Constellation Energy paid quarterly dividends on its common stock at the rate of 43.5 cents per share, equivalent to an annual rate of $1.74 per share.  The dividend is payable April 1, 2008, to shareholders of record at the close of business on March 10, 2008.

                BGE also declared quarterly dividends at the specified rates for all of its outstanding preference stock, payable April 1, 2008, to shareholders of record at the close of business on March 10, 2008.

Financial Statements

The Dec. 31, 2007, unaudited financial statements and supplemental information are attached.

Adjusted Earnings

                Constellation Energy presents adjusted earnings per share (adjusted EPS) in addition to its reported earnings per share in accordance with generally accepted accounting principles (reported GAAP EPS). Adjusted EPS is a non-GAAP financial measure that differs from reported GAAP EPS because it excludes the cumulative effects of changes in accounting

5

principles, discontinued operations, 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, the impact of certain economic, non-qualifying hedges and synfuel earnings. The mark-to-market impact of these hedges is significant to reported results, but economically neutral to the company in that offsetting gains or losses on underlying accrual positions will be recognized in the future. Synfuel earnings are excluded due to the potential for oil-price volatility to result in a difficult-to-forecast phase-out of tax credits.

                We present adjusted EPS 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 more comparable among periods since it excludes the impact of items such as workforce reduction costs or gains and losses on the sale of assets, which may recur occasionally, but tend to be irregular as to timing, thereby distorting comparisons between periods. However, investors should note that this non-GAAP measure involves judgment by management (in particular, judgment as to what is classified as a special item or an economic, non-qualifying hedge to be excluded from adjusted earnings). This non-GAAP measure is also used to evaluate management’s performance and for compensation purposes.

                Constellation Energy also provides its earnings guidance in terms of adjusted EPS. Constellation Energy is unable to reconcile its guidance to GAAP earnings per share because we do not predict the future impact of special items, economic, non-qualifying hedges and synfuel results due to the difficulty of doing so. The impact of special items, economic, non-qualifying hedges and synfuel results could be material to our operating results computed in accordance with GAAP.  We note that such information is not in accordance with GAAP and should not be viewed as a substitute to GAAP information.

Addendum — Amounts Excluded from Adjusted EPS

Non-qualifying Hedges — after-tax gain of $8.0 million, or $0.05 per share

During the fourth quarter of 2007, we recognized an $8.0 million after-tax gain related to certain non-qualifying hedges of gas transportation rights and gas storage contracts, which are economic hedges that do not meet the criteria or are not designated for cash-flow hedge accounting under FAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended, and thus are required to be marked-to-market. This mark-to-market gain is essentially a timing difference that is expected to be offset as we realize the related accrual contracts in cash in future periods.

Change in Maryland Tax Rate — after-tax charge of $(0.7) million, or $0.00 per share

On Nov. 19, 2007, a change in the Maryland corporate income tax rate was signed into law increasing the rate from 7.0 percent to 8.25 percent effective Jan. 1, 2008.  In accordance with FAS No. 109, Accounting for Income Taxes, the impact from adjusting all existing deferred income tax assets and liabilities for the effect of changes in tax laws or rates should be included in operating results in the period that includes the enactment date.  Current income taxes will begin to be recorded at the higher Maryland corporate income tax rate effective in 2008 and will be reflected in our ongoing operating results.

In the fourth quarter of 2007, we recognized a non-recurring $(0.7) million after-tax charge for the net impact of the changes in our Maryland deferred income tax assets and liabilities, net of the related federal deferred income tax benefit.  These adjustments resulted in a $(0.05) per share charge for the adjustment of net deferred tax liabilities of BGE and an offsetting $0.05 per share gain for Merchant.  The favorable Merchant earnings impact of the Maryland tax rate change is primarily attributable to deferred tax assets associated with amounts recorded in Accumulated Other Comprehensive Income for hedging activities.

Synfuel Earnings — after-tax loss of $(19.3) million, or $(0.11) per share

The impact of oil price volatility resulted in a difficult-to-forecast phase-out of tax credits at our facilities that produce synfuel.  Consequently, we have removed the $(19.3) million loss generated during the fourth quarter of 2007 from our results as follows:
