For NextEra Energy Resources, the amount of project development costs capitalized as of the balance sheet date. These costs include land rights and other third-party costs directly associated with the development of a new project. Upon commencement of construction, these costs either are transferred to construction work in progress or remain in other assets, depending upon the nature of the cost. Capitalized development costs are charged to OM expenses when recoverability is no longer probable.

For FPL, FPSC rules limit the recording of allowance for funds used during construction (AFUDC) to projects that cost in excess of this threshold percentage of a utility's plant in service balance, and that require more than one year to complete. FPSC rules allow construction projects below this threshold as a component of rate base.
