NextEra Energy, Inc. NEE announced second-quarter 2015 adjusted earnings of $1.56 per share, beating the Zacks Consensus Estimate of $1.50 by 4%. On a year-over-year basis, earnings climbed 9.1% on the heels of higher revenues from Florida Power & Light Company and NextEra Energy Resources.

On a GAAP basis, NextEra Energy recorded second-quarter earnings of $1.59 per share compared with $1.12 per share a year ago. The variance between adjusted and GAAP earnings, during the quarter, was due to a 5 cent impact of unrealized mark-to-market gain from non-qualifying hedges,  a 1 cent loss associated with other than temporary impairments losses and a merger-related expense of 1 cent.

Total Revenue

In the second quarter, NextEra Energy's operating revenues were $4,358 million, surpassing the Zacks Consensus Estimate by 2.6%. Quarterly revenues increased 8.2% from $4,029 million a year ago.

Segmental Results

Florida Power & Light Company (FPL): In the second quarter, the segment reported revenues of $2,996 million, up 3.7% year over year.

NextEra Energy Resources (NEER): Revenues from this segment shot up nearly 22.1% to $1,265 million from the prior-year quarter. The upside was attributable to higher revenues from the contracted renewable business.

Operational Update

In the quarter under review, NextEra Energy's total operating expenses increased 4.4% year over year to $3,212 million.
