LETTER TO SHAREHOLDERS CONSTELLATION ENERGY HAS TURNED ITON.

In 2005, our performance reached new heights. We reported record-setting results and made significant strategic strides-Including our pending merger with FPL Group -that represent both the culmination of years of hard work and the beginning of an exciting new chapter In our long and distinguished history.

We've maintained our position 'as the leader In competitive energy markets, continually increased productivity and reduced our costs, and consistently achieved earnings growth that ranks among the best In our Industry-all of which have enabled us to deiiver superior totai returns to our shareholders. That's what I call turning it on.

Our earnings per share In 2005-excluding special Items and certain economic hedges that do not qualify for hedge I. accounting-were a record $3.62. That's a 16 percent growth rate over our 2004 adjusted earnings. Between late 2001-when our current management team came together and developed and Implemented our business model-and December 2005, our stock price appreciated 159 percent. During the same time, assuming reinvestment of dividends, our average annual return to

'shareholders was 29 percent

.- We also continue to deliver on our promises. Our commitment to shareholders has Included Increasing dividends approximately In-line with our earnings growth. In January 2006, we announced a 'quarterly dividend Increase of nearly 13 percent-from 33.5 cents per share to37.75 cents per share, equivalent to a new annual rate of Si .51 per share. And with our fourth quarter 2005 financial results, we have met or exceeded our earnings guidance for 17 consecutive -quarters.

RIGHT CHOICES. RIGHT RESULTS.

In late 2001,when the energy industry was inastate of flux, we made acrucialstrategic decision that has led to our current suc-cess. While others were retreating from competitive markets',we decided to aggressively move forward, creating an unmatched combination of portfolio and risk management expertise, outstanding customer focus and advanced logistical capabilities. Our stategy has gaindu significant opportunities and made us a leader all alongl the energy value chain-from the mouth of the mieto the light switch and everywhere Inbetween.

wearethe No.1 provider of competitive energy Inwholesale and retail markets InNorth America. Our wholesale Toda, maretig ad rskmanagement 'operation has built a truly diversified platform across three commodities: power, natural gas and coal. Last year, our Commodities Group added an Integrated natural gas platform that far exceeded growth expectations. And our international coal business Is establishing itself as a growing player, delivering more than 12 million tons of coal In2005 to our own fleet, as well as to customers Inthe United States, Europe and the Far East.

Meanwhile, our retail competitive supply business, Consteilation NewEnergy, continues to strengthen Its position as the largest supplier of electricity to commercial and Industrial customers' In North America, including more than two-thirds of the FORTUNE 100 companies.

Baltimore Gas and Electric,our regulated utility inCentral Maryland, hasa strong track record incustomer service, scoring inthe top quartile In all three J.D. Power surveys. In addition, BGE's focus on keepIng costs low once again placed it Inthe top decile of comparable utilities and contributed significantly to our overall 'ea'rnIngs. As I write this letter, we are continuing to work diligently with Governor Ehrlich and Maryland officials to ease the transition to market-based electric rates, which are' scheduled to take effect July 1,2006. Although rising prices for the coai, oil and natural gas needed to produce electricity have sent energy costs soaring, residential electricity rates In Maryland have been frozen for six years at 6.5 percent below 1993 levels. No utility, Inciuding BGE, can afford to buy power at 2006 prices and collect payment at below 1993 levels. Still, our goal t Isto make any electric rate Increase as manageable as possible for our cstomers, while also providing BGE with the resources.

It needs to Invest InIts Inf rastructure and 'maintain Its financial strength.

.- LETTER TO SHAREHOLDERS POSITION OF STRENGTH.

Others have taken notice of our success. The Edison Electric Institute awarded us the power Industry's highest honor-the prestigious 2005 Edison Award-for our leadership In the competitive energy marketplace. FORTUNE magazine named us one of the 100 Fastest-Growing Companies Inthe country. President George W.Bush visited our flagship Calvert Cliffs Nuclear Power Plant, where he delivered a speech on energy policy and called for a renewed Interest In building the nation's next generation of nuclear power plants.

• While that recognition Is gratifying, It's our successful and balanced business strategy that puts us In a position of strength. Our strategy Ison target. We will continue to build on It and deliver on our financial commitments.

Expanding our participation along the energy value chain Isthe key. We're working to Improve our balance sheet and cash flow, and we use a disciplined Investment approach to grow our business.'We make Investments and acquisitions only If

-they provIde sufficient risk-adjusted returns.

STAYING AHEAD OF THE CURVE.

I believe the'energy Industry Is nearing another phase of major change. This time the major change will be consolidation.

Given the benefits of economies of scale and the advantages of serving diversified geographic areas and customers all along the energy value chain, It makes sense that companies will seek partners to form larger and more efficient operations.

Once again, we're ahead of the curve. In December, we announced our plan to merge with FPL Group. The merger will bring together two oathe strongest, fastest-rowing and most successfui energy companies Ih America. It Is an exciting, strategic corn-bination that will position us as what I call an end-game player.

BECOMING AN END-GAME PLAYER.

When the merger receives the required regulatory and shareholder approvals, our combined company not only will be the No.1 l competitive energy supplier In the United States, It will also be the nation's largest power generator and second-largest electric utility portfolio. a.

Most Importantly, this merger puts us In a position to achieve something very special. Consolidation will Increase In the W

senergy Industry, with a shift from many, smaller companies to fewer, larger companies. The ieaders at the end of this shift will

• be those with a large diversified geographic reach, cost and efficiency advantages produced by economies of scale, and strong balance sheets.

We're taking the right strategic steps now-at a time and with a partner of our own choosing-to secure our place as an end-game player In the energy marketplace of the future.

It's been an exhilarating last four years, with accomplishments beyond even our own expectations. It's all due to the suc-cess of our bold strategy and hehard work of our employees-It's their energy that keeps this company turned on. As we move forward and become an toetetrnes,end-game toofth player In our consolidating ses-grwigan os scesfl Industry, neg I'm confident that cmanesi our strong Aeic. tIsasuccess ec~n,willtatgi continue.or4 I'm glad to be a part of It and hope you are too.

LEVERAGING OUR EXPERTISE TO BENEFIT OUR CUSTOMERS By optimizing the supply and delivery of both fuel and power for our customers-some of the world's largest producers and con-sumers of power, natural gas, oil and coal-we help them successfully manage their energy supply and price risk. Our disciplined focus on physical energy markets and on rigorous risk management drives our success and the success of our customers. For example, we help the Wellesley Municipal Light Plant In Massachusetts meet Its commitment to provide reliable and efficient electricity at fair and competitive rates to more than 27,000 residents. From street lamps to stop lights, from living rooms to classrooms, we meet all of the town's power requirements.

13 14 NUCLEAR BALANCE AND GROWTH As one of the nation's premier nuclear power plant owners and operators, we're demonstrating that nuclear power Is reliable, cost-effective and environmentally friendly. Our nuclear power strategy balances the present with the future. We continuously work to safely Improve production at our five operating nuclear units, which produced 52 percent of the power we generated In 2005. And we're working to provide the framework to help build the next generation of nuclear power plants. Our efforts were recognized when President George W.Bush visited our Industry-leading Calvert Cliffs Nuclear Power Plant (the plant's spent fuel pool Is shown In photo at left) and delivered an energy policy speech that advocated the development and building of new nuclear power plants and reinforced the significant role that nuclear power will play In our nation's energy future.

DOING GOOD Our Panther Creek generating facility-located In Nesquehoning, Pa.-turns otherwise unusable waste coal Into energy.

Anthracite coal mining throughout Eastern Pennsylvania-once the region's booming Industry-left behind countless piles of a black powdery waste coal product called culm. Panther Creek has been part of an Innovative environmental solution, burning the culm to produce electricity. Since beginning operations In 1992, our generating plant has helped remove more than 7 million tons of culm from the Pocono Mountain foothills, leading to the restoration of more than 200 acres of land.

Revenues and Fuel and PurchasedEnergy Expenses Our merchant energy business manages the revenues we realize from the sale of energy to our customers and our costs of procuring fuel and energy. The difference between revenues and fuel and purchased energy expenses is the gross margin of our merchant energy business, and this measure is a useful tool for assessing the profitability of our merchant energy business.

Accordingly, we believe it is appropriate to discuss the operating results of our merchant energy business by analyzing the changes in gross margin between periods. In managing our portfolio, we may terminate, restructure, or acquire contracts. Such transactions are within the normal course of managing our portfolio and may materially impact the timing of our recognition of revenues, fuel and purchased energy expenses, and cash flows.

Gross margin $ 847.4 S 978.7 S 984.6 The decrease in Mid-Atlantic Region gross margin in 2005 compared to 2004 is primarily due to rising commodity prices and hotter than normal weather during the third quarter of 2005, which resulted in higher load-serving costs. In addition, CTC revenues were $33.1 million lower during 2005 compared to the same period of 2004. These decreases in gross margin were partially offset by the absence of coal delivery issues that we experienced in 2004 that had a negative impact in that period. We discuss the coal delivery issues in the Business Environment-Other Factors section.

CTC revenues will continue to decrease as residential, commercial, and industrial customers complete their CTC obligation. CTC revenues will be completely phased-out for residential customers by June 30, 2006 and CTC revenues for commercial and industrial customers will begin to be phased-out after June 30, 2006.
