ALBANY, N.Y. -- Standard & Poor's Ratings Services is warning three U.S. utilities that economic problems in their parent company's home country could endanger their credit ratings.
The rating agency will review Iberdrola's rating for a downgrade because the company gets almost half its revenue from Spain, which is in recession. Worsening conditions there could hurt Iberdrola's profitability.
Iberdrola owns New York utilities Rochester Gas & Electric and New York State Electric and Gas as well as Central Maine Power.
Standard & Poor's currently rates Iberdrola BBB+, three notches above "junk" status. The ratings for its U.S. companies are capped at that level.
Iberdrola is to announce a strategic plan on Oct. 24 and Standard & Poor's said it will revisit the ratings then.
