[1] FPL has identified $1.5 billion to $2.5 billion in potential incremental capital expenditures through 2016 in addition to what is included in the table above.

[2] Includes allowance for funds used during construction (AFUDC) of approximately $28 million, $53 million and $17 million for the remainder of 2014 through 2016, respectively.

[3] Consists of projects that have received FPSC approval. Excludes capital expenditures for the construction costs for the two additional nuclear units at FPL's Turkey Point site beyond what is required to receive an NRC license for each unit.

[4] Includes land, generating structures, transmission interconnection and integration and licensing.

[5] Consists of capital expenditures for new wind projects and related transmission totaling approximately 1,815 MW, including approximately 465 MW in Canada, that have received applicable internal approvals. NEER expects to add new U.S. wind generation of 2,000 MW to 2,500 MW in 2013 through 2015, including 325 MW added to date, at a total cost of up to $3.5 billion to $4.5 billion.

[6] Consists of capital expenditures for new solar projects and related transmission totaling approximately 600 MW that have received applicable internal approvals, including equity contributions associated with a 50% equity investment in a 550 MW solar project. Includes approximately $1 billion of total estimated costs associated with the pending acquisition of the development rights for a 250 MW solar project that is expected to close in mid-2014, subject to certain conditions precedent, and construction of the project, which is expected to be completed in 2016. Excludes solar projects requiring internal approvals with generation totaling 47 MW with an estimated cost of approximately $120 million.

[7] Includes nuclear fuel.

[8] Consists of capital expenditures that have received applicable internal approvals.

[9] Includes capital expenditures totaling approximately $1.4 billion for the remainder of 2014 through 2018 for construction of a natural gas pipeline system that has received applicable internal approvals, including approximately $885 million of equity contributions associated with a 33% equity investment in the northern portion of the natural gas pipeline system and $525 million for the southern portion, which includes AFUDC of approximately $1 million, $7 million, $20 million and $12 million for the remainder of 2014 through 2017, respectively. The natural gas pipeline system is subject to certain conditions, including FERC approval. A FERC decision is expected in 2015. See Contracts below.
