[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. Excludes potential incremental capital expenditures totaling approximately $1.6 billion for the natural gas pipeline system. See Part II, Item 5. (c)(i).

[2] Includes allowance for funds used during construction (AFUDC) of approximately $35 million, $57 million, $50 million and $27 million for the remainder of 2013 through 2016, respectively.

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

[4] 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.

[5] Includes nuclear fuel.

[6] Consists of capital expenditures for new wind projects and related transmission totaling approximately 450 mw, including approximately 125 mw in Canada, that have received applicable internal approvals. Excludes new Canadian wind projects requiring internal approvals with generation totaling approximately 470 mw in 2014 and 2015, with an estimated total cost of approximately $1.3 billion to $1.7 billion. NEER expects to add up to 1,500 mw of new U.S. wind generation through 2014 at a total cost of up to $3 billion.

[7] Consists of capital expenditures for new solar projects and related transmission totaling 545 mw that have received applicable internal approvals, including equity contributions associated with a 50% equity investment in a 550 mw solar project. Excludes a solar project requiring internal approval with generation totaling 250 mw with an estimated cost of approximately $600 million to $800 million. Additionally, NEER expects to add up to 300 mw of incremental solar generation at a cost of up to $1 billion through 2016.

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