Leases [Abstract]
Leases	LeasesNEE has operating and finance leases primarily related to purchased power agreements, land use agreements that convey exclusive use of the land during the arrangement for certain of its renewable energy projects and substations, buildings and equipment. Operating and finance leases primarily have fixed payments with expected expiration dates ranging from 2021 to 2052, with the exception of operating leases related to three land use agreements with an expiration date of 2106, some of which include options to extend the leases up to 20 years and some have options to terminate at NEE's discretion. At December 31, 2020, NEE’s ROU assets and lease liabilities for operating leases totaled approximately $535 million and $541 million, respectively; the respective amounts at December 31, 2019 were $499 million and $498 million. At December 31, 2020, NEE’s ROU assets and lease liabilities for finance leases totaled approximately $128 million and $124 million, respectively; the respective amounts at December 31, 2019 were $62 million and $56 million. NEE’s lease liabilities at December 31, 2020 and 2019 were calculated using a weighted-average incremental borrowing rate at the lease inception of 3.81% and 3.73%, respectively, for operating leases and 3.50% and 3.15%, respectively, for finance leases, and a weighted-average remaining lease term of 33 years and 31 years, respectively, for operating leases and 25 years and 14 years, respectively, for finance leases. At December 31, 2020, expected lease payments over the remaining terms of the leases were approximately $1.2 billion with no one year being material. NEE's operating lease cost for the years ended December 31, 2020 and 2019 totaled approximately $95 million and $91 million, respectively. During the year ended December 31, 2020 and 2019, NEE's ROU assets obtained in exchange for operating lease obligations totaled approximately $121 million and $450 million, respectively, and in 2019 primarily relate to leases acquired with the Gulf Power and Trans Bay acquisitions (see Note 6). Other operating and finance lease-related amounts were not material to NEE's consolidated statements of income or cash flows for the periods presented.NEE has sales-type leases primarily related to a natural gas and oil electric generation facility and certain battery storage facilities that sell their electric output under power sales agreements to third parties which provide the customers the ability to dispatch the facilities. At December 31, 2020 and 2019, NEE recorded a net investment in sales-type leases of approximately $47 million and $50 million, respectively, and losses at commencement of sales-type leases due to the variable nature of the lease payments of approximately $20 million for the year ended December 31, 2018, which are recorded in gains on disposal of businesses/assets - net in NEE's consolidated statements of income. At December 31, 2020, the power sales agreements have expiration dates from 2021 to 2043 and NEE expects to receive approximately $117 million of lease payments over the remaining terms of the power sales agreements with no one year being material.
