Substantially all of FPL's properties are subject to the lien of FPL's mortgage, which secures most debt securities issued by FPL. The weighted annual composite depreciation and amortization rate for FPL's electric plant in service, including capitalized software, but excluding the effects of decommissioning, dismantlement and the depreciation adjustments discussed in the following sentence, was approximately 3.7%, 3.9% and 3.8% for 2020, 2019 and 2018, respectively. In accordance with the 2016 rate agreement (see Note 1 - Rate Regulation - FPL Base Rates Effective January 2017), FPL recorded the reversal of reserve amortization of approximately $1 million, $357 million and $541 million in 2020, 2019 and 2018, respectively. During 2020, 2019 and 2018, FPL capitalized AFUDC at a rate of 6.22%, 6.22% and 5.97%, respectively, which amounted to approximately $79 million, $80 million and $114 million, respectively.

NEER - At December 31, 2020, wind, solar and nuclear plants represented approximately 55%, 13% and 8%, respectively, of NEER's depreciable electric plant in service and other property; the respective amounts at December 31, 2019 were 54%, 12% and 10%. The estimated useful lives of NEER's plants range primarily from 30 to 35 years for wind plants, 25 to 30 years for solar plants and 23 to 47 years for nuclear plants. NEER's oil and gas production assets represented approximately 14% and 15% of NEER's depreciable electric plant in service and other property at December 31, 2020 and 2019, respectively. A number of NEER's generation, regulated transmission and pipeline facilities are encumbered by liens securing various financings. The net book value of NEER's assets serving as collateral was approximately $11.0 billion at December 31, 2020. Interest capitalized on construction projects amounted to approximately $168 million, $135 million and $94 million during 2020, 2019 and 2018, respectively.
