*Normalization Methodology: With the creation of UMERC, Residential and Small C&I sales in both the WPSC Rate Zone and the WEPCo Rate Zone are now weather normalized using Iron Mountain weather.  Both zones use the same monthly weather normalization coefficients for heating and cooling degree days (base = 65).  Twenty year rolling average weather is used for “normal” weather.
