Standard&Poor's Ratings Services has assigned its 'A' rating, and stable outlook, to Indianapolis, Ind.'s thermal energy system revenue bonds, series 2013A and 2013B. At the same time, Standard&Poor's has affirmed its 'A' rating on Indianapolis' debt outstanding issued for Citizens Thermal Energy. The outlook is stable. The 'A' ratings reflects what we consider to be the steam utility's continued favorable regulatory climate, and good growth of the unregulated chilled water utility. We believe a small-but-stable customer base and competitive rates further support the ratings. Additional credit strengths include: The strong, in our view, business position of the regulated steam division, which benefits from a fuel cost adjustment mechanism; and Long-term contracts with highly rated leading customers
