Portland General Electric Company (NYSE:POR) today reported net income of $26 million, or $0.34 per diluted share, for the second quarter of 2012, compared with $22 million, or $0.29 per diluted share, for the second quarter of 2011. The increase in net income was primarily the result of favorable power supply operations, partially offset by a decline in the volume of retail energy deliveries. For the six months ended June 30, 2012, net income was $75 million, or $0.99 per diluted share, compared with $91 million, or $1.21 per diluted share for the six months ended June 30, 2011. The decrease in net income was primarily driven by a 3% decrease in residential energy deliveries as a result of warmer weather in 2012, partially offset by favorable power supply operations. Total revenues for the second quarter of 2012 were up slightly compared with the second quarter of 2011. A 5.5% decline in residential energy deliveries due to warmer weather in 2012 and an overall decrease in average retail prices, driven by a decrease in projected power costs for 2012, were offset by refunds to customers recorded in the second quarter of 2011, with no comparable refunds recorded in the second quarter of 2012. Purchased power and fuel expense decreased $13 million, or 8%, in the second quarter of 2012 compared with the second quarter of 2011, primarily driven by a 19% decline in the average variable cost of purchased power. During the second quarter of 2012, a substantial amount of lower-cost purchased power economically displaced thermal generation, with thermal generation representing 5% of the total retail requirement compared to 10% for the comparable period of 2011. The average variable power cost decreased to $30.53 per MWh in the second quarter of 2012 from $33.28 per MWh in the second quarter of 2011.
