I will now turn the call over to, Ben.
Thanks, Paul and good morning. Today, we reported second quarter earnings of $0.38 per share compared with $0.33 per share in 2011. New electric rates in Colorado, combined with warmer than normal June weather across our service territory and continued strong expense control, led to our solid second quarter results.
As a result, we remain on track to deliver 2012 earnings in the lower half of our earnings guidance range of $1.75 to $1.85 per share. Teresa will discuss our quarterly results and earnings guidance in greater detail in a few moments.
I will now provide you a few recent developments, starting with an operational update. I am pleased to report that our operating systems performed very well throughout the recent period of hot weather across our service territory. Record temperatures drove new peak demands in several states with only minimal service interruptions.
In addition to the record heat, numerous severe storms occurred in our northern service territory. Excellent response, planning and performance during system outage events minimized customer impacts and our crew has performed their work safely under difficult conditions.
In addition to reliability, our efforts to provide value to our customers are also reflected in two recently proposed transactions. This summer, we agreed to purchase the Brush assets for $75 million. The Brush assets consist of three gas-fired generating units with a total capacity of 237 megawatts. These plants currently provide energy and capacity to PSCo under purchase power agreements that are set to expire in 2017 and 2022.
While smaller, this transaction is very similar to our acquisition of generation assets from Calpine in late 2010 which provided benefits to both customers and investors. The Brush acquisition has many positive attributes including saving our customers' money beginning in the first year. Additionally, owning these peaking plants will give us greater control over our resources. Purchase is subject to various regulatory approvals including the Colorado Commission. We anticipate this transaction will close in early 2013.
