Question:
estimated payments under natural gas pipeline and storage capacity commitments for the next three years total how much , in millions?


pre_text: power purchase contracts dominion has entered into contracts for long-term purchases of capacity and energy from other utilities , qualifying facilities and independent power producers .
as of december 31 , 2002 , dominion had 42 non-utility purchase contracts with a com- bined dependable summer capacity of 3758 megawatts .
the table below reflects dominion 2019s minimum commitments as of december 31 , 2002 under these contracts. .
post_text: capacity and other purchases under these contracts totaled $ 691 million , $ 680 million and $ 740 million for 2002 , 2001 and 2000 , respectively .
in 2001 , dominion completed the purchase of three gener- ating facilities and the termination of seven long-term power purchase contracts with non-utility generators .
dominion recorded an after-tax charge of $ 136 million in connection with the purchase and termination of long-term power purchase contracts .
cash payments related to the purchase of three gener- ating facilities totaled $ 207 million .
the allocation of the pur- chase price was assigned to the assets and liabilities acquired based upon estimated fair values as of the date of acquisition .
substantially all of the value was attributed to the power pur- chase contracts which were terminated and resulted in a charge included in operation and maintenance expense .
fuel purchase commitments dominion enters into long-term purchase commitments for fuel used in electric generation and natural gas for purposes other than trading .
estimated payments under these commitments for the next five years are as follows : 2003 2014$ 599 million ; 2004 2014$ 311 million ; 2005 2014$ 253 million ; 2006 2014$ 205 mil- lion ; 2007 2014$ 89 million ; and years beyond 2007 2014$ 215 mil- lion .
these purchase commitments include those required for regulated operations .
dominion recovers the costs of those pur- chases through regulated rates .
the natural gas purchase com- mitments of dominion 2019s field services operations are also included , net of related sales commitments .
in addition , dominion has committed to purchase certain volumes of nat- ural gas at market index prices determined in the period the natural gas is delivered .
these transactions have been designated as normal purchases and sales under sfas no .

natural gas pipeline and storage capacity commitments dominion enters into long-term commitments for the purchase of natural gas pipeline and storage capacity for purposes other than trading .
estimated payments under these commitments for the next five years are as follows : 2003 2014$ 34 million ; 2004 2014$ 23 million ; 2005 2014$ 13 million .

the lessors have an aggregate financing commitment from equity and debt investors of $ 2.2 billion , of which $ 1.6 billion has been used for total project costs to date .
dominion , in its role as construction agent for the lessors , is responsible for com- pleting construction by a specified date .
in the event a project is terminated before completion , dominion has the option to either purchase the project for 100 percent of project costs or terminate the project and make a payment to the lessor of approximately but no more than 89.9 percent of project costs .
upon completion of each individual project , dominion has use of the project assets subject to an operating lease .
dominion 2019s lease payments to the lessors are sufficient to provide a return to the investors .
at the end of each individual project 2019s lease term , dominion may renew the lease at negotiated amounts based on project costs and current market conditions , subject to investors 2019 approval ; purchase the project at its original construction cost ; or sell the project , on behalf of the lessor , to an independent third party .
if the project is sold and the proceeds from the sale are insufficient to repay the investors , dominion may be required to make a payment to the lessor up to an amount rang- ing from 81 percent to 85 percent of the project cost depending 85d o m i n i o n 2019 0 2 a n n u a l r e p o r t .
