A residential customer consuming 600 kwh of electricity will be paying $210.70, a decrease of $6.66 compared to rates effective February 1, The decrease in the typical residential bill is due to the decrease in the energy cost adjustment factor (-$8.16), the increase in the Purchased Power Adjustment Clause rate (+$1.49), and the increase in the Renewable Energy Infrastructure Cost Recovery Provision (+$0.01). The Company s fuel composite cost of generation increased cents per million BTU to 2, cents per million BTU. The Company s Distributed Generation ( DG ) energy component increased cents per kwh to cents per kwh. The composite cost of purchased energy decreased cents per kwh to cents per kwh. The attached sheets set forth the energy cost adjustment factor in cents per kwh for each rate schedule that applies for prorata use beginning March 1, Attachments cc: Division of Consumer Advocacy Very truly yours, /s/ Dean K.
