Third Quarter 2015 Highlights LaPorte Substation Financial Summary Platte River reported operating income of $18.6 million for the first nine months, compared with $22.5 million reported during the same period in 2014. Operating revenues increased $0.8 million from the same period last year mainly due to a $5.3 million increase in Municipal sales partially offset by a $4.5 million decrease in surplus sales as a result of a soft market. The increase in Municipal sales was primarily the result of a 2.5% increase in wholesale rates. Total operating expenses were up $4.6 million. Operation and maintenance expenses were up $5.9 million primarily due to purchased power and transmission expenses associated with new wind resources, as well as increases in demand side management incentives, and personnel expenses. Depreciation decreased $1.3 million as many Rawhide and Craig assets reached the end of their depreciable life in 2014. Income before contributions was $13.0 million, down from the $16.2 million reported during the same period last year. Total debt service coverage for the first nine months was 1.81 times. Power Production During the first nine months of 2015, Rawhide Unit 1 reported a net plant capacity factor of 92.7%, up slightly from the 91.5% reported for the same period last year. Craig Units 1 and 2 reported a combined plant capacity factor of 72.2%, down from the 86.9% reported last year. The units experienced maintenance issues and were also held back due to the soft surplus sales market. Other generation included 195,873 MWh of wind, 436,760 MWh of hydro-power, and Platte River’s peaking units produced 41,248 MWh. Operating Statistics Platte River supplied 2,414,557 MWh to its four municipal owners, up 2% from the first nine months last year. The total monthly municipal billing demand was up 0.1% from the same period last year.
