FPL’s adjusted earnings for the year may go down. The interruption seen at its Seabrook nuclear power plant and very low wind resources may be the causes of its low earnings.

The largest utility in Florida, the company is owned by FPL and is the biggest producer of wind power in the United States. At Juno Beach, Florida, FPL owns and operates about 39,000 MW of generating capacity across the United States. It sells energy commodities, transmits and distributes electricity to more than 4.5 million customers in Florida.

According to the company, its 2010 adjusted earnings will now stand at around $4.25 to $4.85 a share, on the back of the Seabrook plant which is expected to be back on track before the current year ends.

Company’s shares closed at $53.82, down by 1.25 percent, on Tuesday on the New York Stock Exchange.

Analysts surveyed by Thomson Reuters, predicted company’s 2009 earnings per share of $4.15 and 2010 earnings per share of $4.56.
