S&P Revamps Public Power Rating Scale
Standard & Poor's has revised its business profile scale for public power agencies to give investors more details to figure out each rated utility's ability to compete in a deregulated market.
It expanded its five-point scale to a 10-point scale, similar to the rating system used for investor-owned utilities. A "1" rating is the "most capable of competing," so that investors can better gauge a public power's ability to meet competitive challenges and market developments, such as separation of generation and transmission facilities.
