For the twelve months ended Dec. 31, 2004, the company reported a loss per share of $0.51, or a net loss of $221.2 million, compared to earnings per share of $0.71, or net income of $282.0 million, for the year ended Dec. 31, 2003. The year-end results include a correction to the tax provision within discontinued operations previously recorded in the consolidated statements of operations for the three and nine months ended Sept. 30, 2004. The company will restate earnings for the three and nine months ended Sept. 30, 2004 to make the correction, which will lower the effective tax rate on discontinued operations and improve net results by approximately $36.5 million, or $0.09 per share, for the nine months ended Sept. 30, 2004.

Pete Cartwright, Calpine president and chief executive officer, stated, “Despite ongoing business challenges, Calpine enhanced the value of the enterprise through successful financing activities, advancement of our business strategy and the strengthening of our commercial operations. During the year, we completed $2.1 billion of liquidity-enhancing transactions, repurchased or refinanced approximately $1.8 billion of corporate debt, redeemed in full our HIGH TIDES I and II preferred securities and refinanced $2.4 billion of maturing project debt. Calpine also increased power production by 17% and improved plant efficiencies.

“Earnings were disappointing for the year,” continued Cartwright. “Although we continued to see improvements in spark spreads, the margins for our product remained low in certain markets and were offset by increased operating costs, depreciation and interest expense associated with additional capacity coming into service. And while our gas portfolio remains strong, we recorded a non-cash impairment charge associated with certain oil and gas fields in South Texas and Offshore Louisiana. Also, during the quarter, earnings were impacted by equipment failures on some of Calpine’s gas and steam turbines.

“I expect Calpine will continue to face its share of challenges in 2005, but I am confident that we will successfully execute our programs to further enhance liquidity, reduce corporate debt and strengthen our core operations. Today, we are evaluating the potential sale of certain power plants, including our Saltend facility in the United Kingdom. We expect these opportunities, together with the completion of nearly $900 million of liquidity-enhancing transactions, will allow us to to repurchase more than $1 billion of corporate debt.

“We will continue to focus on increasing the value of our contractual portfolio, Calpine Energy Services’ activities, and our power services and parts manufacturing businesses. Longer-term, Calpine will work to advance open, competitive markets and enhance value for our customers.”

Restatement of Third Quarter 2004 Results

As indicated above, the company will restate earnings for the three and nine months ended Sept. 30, 2004 to make a correction to the tax provision within discontinued operations. The correction will lower the effective tax rate on discontinued operations and improve net results by approximately $36.5 million, or $0.09 per share, for the nine months ended Sept. 30, 2004. The company had provided for taxes on the discontinued operations income at statutory rates, rather than a lower effective rate, to reflect the benefits of permanent differences associated with tax laws versus GAAP accounting rules. See the schedule included in Supplemental Data for further details of the impact. The company will also make reclassifications of the tax provision between continuing and discontinued operations for prior reporting periods, which will not change total net income in these prior periods. The company detected the error in the first quarter of 2005 and has made changes to its internal controls. The company intends to file an amended Form 10-Q for the period ended Sept. 30, 2004, on or prior to the date that it files its Form 10-K for the year ended Dec. 31, 2004, to restate the tax provision within discontinued operations for the affected periods and to amend its disclosure in Part I, Item 4 “Controls and Procedures” to report its conclusion that its controls over the recording of the tax provision at Sept. 30, 2004 were ineffective due to the error, which constituted a “material weakness” under Public Company Accounting Oversight Board standards. In accordance with Section 404 of the Sarbanes-Oxley Act, the company and its auditors continue to assess the overall controls environment and its effectiveness. As a result of the third quarter error, the company may conclude that, with respect to the recording of taxes within discontinued operations, its controls environment as of Dec. 31, 2004 was ineffective, and the company’s external auditors may issue an adverse opinion on the company’s controls environment as of Dec. 31, 2004 because of this issue. The auditors’ opinion on controls will be provided with the company’s year-end audited financial statements when they are completed and filed, which is expected to be on or before March 16, 2005.

2004 Fourth Quarter and Year-End Financial Results

For the three months ended Dec. 31, 2004, the company reported revenue of $2.3 billion, representing an increase of 22% over the same period in the prior year, and a net loss per share of $0.39, or a net loss of $172.8 million, compared to earnings per share of $0.29, or net income of $119.6 million for the same quarter in the prior year.

For the three months ended Dec. 31, 2004, average capacity in operation increased by 23% to 26,435 megawatts. The company generated approximately 24.0 million megawatt-hours, which equated to a baseload capacity factor of 45.6%, and realized an average spark spread of $21.36 per megawatt-hour. For the same period in 2003, Calpine generated 20.4 million megawatt-hours, which equated to a capacity factor of 48.9%, and realized an average spark spread of $23.90 per megawatt-hour.

Despite improvements in market fundamentals, total spark spread, which increased by $25.3 million, or 5%, in the fourth quarter of 2004 compared to the same period in 2003, did not increase commensurately with the increases in plant operating expense, transmission purchase expense, depreciation and interest expense associated with new power plants coming on-line.

Calpine recorded an impairment charge of approximately $201.5 million for certain oil and gas reserves, most notably on South Texas properties, following the receipt of the independent engineer’s report for year-end 2004, which reduced proved reserves 6% below Calpine’s year-end projection before receiving the engineer’s report. Following the reduction in proved reserves and the non-cash impairment charge, Calpine’s estimated total proved reserves of 389 billion cubic feet equivalent (bcfe) will have an estimated value of approximately $912 million (based on the present value of estimated future cash flows discounted at 10% in accordance with SEC guidelines), compared to a carrying value of approximately $607 million.

In addition, during the fourth quarter of 2004 Calpine recorded approximately $45.3 million for equipment failure costs and a charge of $28.6 million for the cancellation of heat recovery steam generator orders on two of its development projects. The company also recognized gains totaling $76.4 million on debt repurchases of $394.0 million.

As a result of provisions in The American Jobs Creation Act of 2004 signed into law on Oct. 22, 2004, Calpine recorded a reduction of $66.9 million, or $0.15 per share, in tax expense in the fourth quarter of 2004 on repatriated funds, which is mostly netted within the discontinued operations gain. The company had recorded approximately $78.8 million of tax expense in the third quarter of 2004 related to the repatriation of net cash proceeds from Canada to the United States following the sale of oil and gas assets in Canada.

2004 Twelve-Month Results

For the twelve months ended Dec. 31, 2004, the company reported revenue of $9.2 billion, representing an increase of 4% over the same period in the prior year. For the twelve months ended Dec. 31, 2004, Calpine netted approximately $1.7 billion of sales of purchased power for hedging and optimization with purchased power expense, compared to $0.3 billion in the prior year (netting in 2003 occurred only in the fourth quarter). This was due to the adoption on Oct. 1, 2003, on a prospective basis, of new accounting rules related to presentation of non-trading derivative activity. Adjusted for the netting, total revenue would have grown by approximately 19% versus the reported 4% growth in revenue. For the twelve months ended Dec. 31, 2004, the company reported a loss per share of $0.51, or a net loss of $221.2 million, compared to earnings per share of $0.71, or net income of $282.0 million, for the same period in the prior year.

For the twelve months ended Dec. 31, 2004, the company generated 96.5 million megawatt-hours, which equated to a baseload capacity factor of 49.8%, and realized an average spark spread of $21.24 per megawatt-hour. For the same period in 2003, Calpine generated 82.4 million megawatt-hours, which equated to a capacity factor of 53.2%, and realized an average spark spread of $23.90 per megawatt-hour.

Gross profit decreased by $409.1 million, or 54%, to $355.1 million in the twelve months ended Dec. 31, 2004, over the same period in the prior year, primarily due to: i) $202.1 million of impairment charges for certain oil and gas reserves; ii) non-recurring other revenue of $67.3 million recognized in the twelve months ended Dec. 31, 2003 from the settlement of contract disputes with, and claims against, Enron Corp.; iii) the recording of approximately $54.3 million for equipment failure costs within plant operating expense in 2004, compared to $11.0 million in 2003; iv) the amortization of $29.0 million in the twelve months of 2004 of the DIG C-20 gain recorded in the fourth quarter of 2003 due to the cumulative effect of a change in accounting principle; and v) market fundamentals, which caused total spark spread, despite a total increase of $79.2 million, or 4%, to not increase commensurately with additional plant operating expense, transmission purchase expense and depreciation costs associated with new power plants coming on-line.

During the twelve months ended Dec. 31, 2004, financial results were affected by a $387.9 million increase in interest expense and distributions on trust preferred securities, as compared to the same period in 2003. This occurred as a result of higher debt balances, higher average interest rates and lower capitalization of interest expense as new plants entered commercial operation. In addition, prior year results benefited from recording $52.8 million in income from unconsolidated investments in power projects, from the termination of a power purchase agreement by the Acadia joint venture.

Other income increased by $103.0 million to $149.1 million during the twelve months ended Dec. 31, 2004, as compared to the same period in 2003, primarily due to: i) pre-tax income in the amount of $171.5 million, net of transaction costs and the write-off of unamortized deferred financing costs, associated with the restructuring of power purchase agreements for the Newark and Parlin power plants and the sale of an entity holding a power purchase agreement; ii) a $16.4 million pre-tax gain from the restructuring of a long-term gas supply contract net of transaction costs; and iii) a $12.3 million pre-tax gain from the King City restructuring transaction related to the sale of the company’s debt securities that had served as collateral under the King City lease, net of transaction costs. In 2003, the company recorded a gain of $62.2 million on the sale of oil and gas properties and a gain of $57.0 million from a contract termination at the RockGen facility.

In 2004, the company recorded a charge of $42.4 million for equipment cancellation costs, primarily related to cancellation of heat recovery steam generator orders on two of its development projects. In 2003, there were $64.4 million in equipment cancellation charges. Also, during the twelve months ended Dec. 31, 2004, foreign currency transaction losses were $25.1 million, compared to losses of $33.3 million in the corresponding period in 2003.

The company also recognized gains totaling $246.9 million on repurchases of debt for the twelve months ended Dec. 31, 2004 compared to $278.6 million for the twelve months ended Dec. 31, 2003. Loss before discontinued operations and cumulative effect of a change in accounting principle was $418.0 million, or $0.97 per share, in 2004.

Income from discontinued operations, net of tax increased by $181.9 million during the twelve months ended Dec. 31, 2004, as compared to the same period in 2003, as a result of the sale of its Canadian and certain U.S. oil and gas assets during the third quarter of 2004 and the sale of the company’s interest in the Lost Pines facility in the first quarter of 2004.

Liquidity and Finance Program Highlights

Enhancing liquidity, reducing corporate debt and addressing near-term debt maturities continued to drive Calpine’s financing program in 2004. During the year, Calpine successfully enhanced its financial position through a significant number of transactions:

| • | Refinanced Calpine Construction Finance Company II project debt through the issuance of $2.4 billion of Calpine Generating Company bonds and term loans;
| • | Completed approximately $2.1 billion of liquidity transactions including the sale of its Canadian and certain U.S. natural gas reserves for $847.8 million;
| • | Redeemed in full $598.5 million of HIGH TIDES I and II, and a portion of HIGH TIDES III, totaling $115.0 million; and
| • | Repurchased approximately $1.8 billion of existing corporate debt, resulting in a net gain of $246.9 million after the write-off of unamortized discounts and deferred financing costs.

A detailed listing of debt repurchased along with the current outstanding debt is included in the appendices to the conference call presentation.

Calpine ended the year with approximately $1.6 billion of cash and credit available upon meeting certain conditions. This included cash and cash equivalents on hand of approximately $0.8 billion, the current portion of restricted cash of approximately $0.6 billion and approximately $0.2 billion of borrowing capacity available under the company’s various credit facilities upon meeting certain conditions.

2004 Operations Update

The company turned in another strong year of operations, adding more than 4,400 megawatts of power generation capacity, improving plant performance and reducing turbine inventory. Today, Calpine owns or leases 92 natural gas-fired and geothermal power plants. These efficient, reliable power plants can generate more than 26,560 megawatts of electricity for wholesale and retail customers. In 2004, Calpine:

| • | Exceeded the industry average safety performance, with a 0.48 Lost Time Accident (LTA) rate for all Calpine employees – well below the Bureau of Labor Statistics LTA industry benchmark of 0.80;
| • | Operated its natural gas-fired and geothermal power plants with an average availability of 92.6%, compared to 91.2% in 2003;
| • | Generated a record 96.5 million megawatt-hours, representing a 17% increase over 2003 levels, and delivered 147.7 million megawatt-hours to load-serving and end-use customers;
| • | Lowered Calpine’s average baseload heat rate to 7,120 million British thermal units per kilowatt-hour for the year, compared to 7,253 in 2003;
| • | Benefited from productivity improvements and economies of scale, with regular plant operating expense (based on a trailing 12-month period at an assumed 70% capacity factor) declining to $4.56 per megawatt-hour from $4.96 per megawatt-hour in 2003;

| • | Produced 46 bcfe of proved natural gas reserves, representing approximately 7% of Calpine’s fuel consumption. Total proved reserves as of Dec. 31, 2004 were 389 bcfe.

New Power Contracts

Throughout 2004, Calpine continued to enhance its portfolio of contracted generation with the addition of new power contracts. Today, the company is pursuing more than 22,000 megawatts of power sales opportunities throughout the North American market. As of Dec. 31, 2004, Calpine’s contractual portfolio included:

| • | A total of 149 power sales contracts with an average life of approximately eight years. These represent power sales to 97 customers with an average credit rating of BBB+;
| • | More than $1.9 billion of estimated spark spread to be generated from Calpine’s 2005 contracted power sales (55% of total 2005 generation capacity under contract); and

New Market Opportunities

As market conditions have improved in several major U.S. power markets, so have Calpine’s commercial operations, including its power services and parts and manufacturing businesses. In 2004, Calpine:

| • | Signed a letter of intent for the joint construction of the first North American power plant utilizing General Electric’s (GE) new H-System gas turbine technology at Calpine’s Inland Empire site in southern California. GE will purchase development rights and fund construction for a 775-megawatt combined-cycle plant. Calpine will provide program management services during construction, market electricity from the plant and, after an extended period of GE ownership and operation, ultimately purchase the plant;
| • | Launched NewSouth Energy LLC (NSE). This new Atlanta, Ga.-based energy venture was created to better focus on wholesale power customers and energy markets in the Southeast. NSE will have access to Calpine’s 7,100-megawatt portfolio of efficient, gas-fired power plants in operation and under construction throughout the Southeast.
| • | Entered into 20 new power services transactions of various lengths, a 25% increase over 2003, most recently entering into a three-year agreement to provide operations and maintenance services to two Indiana generation and transmission cooperatives;
| • | Achieved a performance milestone for Power Systems Mfg., LLC’s (PSM’s) new 501F transition piece. Completed a successful first phase of inspection of its transition pieces at the Channel Energy Center after more than 8,000 hours of operation and 60 equivalent starts; and
| • | Enhanced PSM’s competitive advantage. Calpine’s parts and manufacturing subsidiary was awarded 14 patents in 2004, bringing its total patents held to 31.

(1) |  | This non-GAAP measure is presented not as a measure of operating results, but rather as a measure of our ability to service debt and to raise additional funds. It should not be construed as an alternative to either (i) income from operations or (ii) cash flows from operating activities. It is defined as net income less income from unconsolidated investments, plus cash received from unconsolidated investments, plus provision for tax, plus interest expense (including distributions on trust preferred securities and one-third of operating lease expense, which is management’s estimate of the component of operating lease expense that constitutes interest expense), plus depreciation, depletion and amortization. The interest, tax and depreciation and amortization components of discontinued operations are added back in calculating EBITDA, as adjusted.
(2) |  | This non-GAAP measure is presented as a further refinement of EBITDA, as adjusted, to reflect the company’s ability to service debt with cash.
(3) |  | Does not include MWh generated by unconsolidated investments in power projects.
(4) |  | From continuing operations.
(5) |  | Amounts based on Calpine’s ownership percentage.

APPENDIX E: CONTRACTUAL PORTFOLIO DEFINITIONS The following detailed reports represent several data points for Calpine's power generation portfolio as of December 31, 2004. Estimated Generation Baseload - Estimated generation, in millions of megawatt hours, represents the baseload generation capacity of Calpine's fleet based upon a 95% plant availability level. This availability factor is used to account for scheduled maintenance and other miscellaneous outages. It also takes into account the generation capacity year-by-year as a result of our current estimates of commercial operation dates for those plants currently in construction. Peaking - Estimated generation, in millions of megawatt hours, represents a peaking generation capacity based upon a 30% plant availability and dispatch factor or higher if a plant-specific contract dictates.

#####

APPENDIX E: CONTRACTUAL PORTFOLIO DEFINITIONS (continued) Contractual Generation This represents in millions of megawatt hours, the baseload and peaking generation under contract. For those contracts that are take or pay, the contractual generation estimate assumes the customers take 100% of the contracted power. Contracts Announced / Signed Subsequent to December 31, 2004 Contracts that have been announced and, or signed subsequent to December 31, 2004 are not reflected in this data. Such contracts, as they are finalized, will be reflected in future Contractual Portfolios. % Sold Calculated as the contractual generation divided by the estimated generation. Contractual Spark Spread Represents the contractual or "locked in" spark spread embedded in the company's contracted portfolio. Also includes the value of the company's equity gas reserves which is represented by the market price of gas less operating costs.
