[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 $19 million, $48 million, $57 million and $26 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 710 MW, including approximately 385 MW in Canada, that have received applicable internal approvals. Excludes new Canadian wind projects requiring internal approvals with generation totaling approximately 80 MW in 2014, with an estimated remaining cost of approximately $200 million. 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 1,045 MW that have received applicable internal approvals, including equity contributions associated with a 50% equity investment in a 550 MW solar project. Includes approximately $1.1 billion of estimated costs associated with the pending acquisition of a 250 MW solar project that is expected to close in early 2014, subject to certain conditions precedent, and complete construction in 2016.

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

[9] Excludes new natural gas pipeline system requiring certain external and internal approvals with an estimated total cost of approximately $1.6 billion. See Part II, Item 5. (c)(i) in the Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2013 for NEE and FPL.
