MidAmerican Transmission builds upon the significant operational and
ownership experience gained by MidAmerican through its subsidiaries’
ownership of existing electric transmission systems to provide cost-effective,
reliable transmission solutions for wholesale customers.|
The transmission delivery team has developed approximately $1.6 billion of
transmission projects at voltages of 345 kilovolts and higher and has
extensive experience in traditional utility and stand-alone transmission
MidAmerican Transmission is committed to long-term ownership of transmission
assets and is working to acquire transmission assets and develop transmission
projects within the regulated competitive frameworks that exist in the U.S.
and Canada. It has two established joint ventures with transmission assets
that are operational or under construction and is engaged in various stages
of joint venture development with other entities.
MidAmerican Transmission, along with subsidiaries of American Electric Power
Company, indirectly owns a 50 percent interest in Electric Transmission Texas.
ETT owns and operates electric transmission assets in the Electric
Reliability Council of Texas.
ETT forecasts to complete a total of approximately $1.5 billion of
Competitive Renewable Energy Zone projects before the end of 2013, with $207
million in-service at year-end 2012. Additionally, ETT is developing or
constructing approximately $1.5 billion of transmission projects within
ERCOT that were transferred from AEP subsidiaries. Of these transmission
projects, a total of $672 million were in-service at year-end 2012, with the
remaining projects forecast to be completed between 2013 and 2022. ETT’s
transmission system included 562 line miles of transmission and 19
substations at year-end 2012.
MidAmerican Transmission indirectly owns a 25 percent interest in the Prairie
Wind Transmission project in Kansas, which has received the necessary
approvals from the Federal Energy Regulatory Commission and the Southwest
Power Pool. Construction began in 2012. The project is expected to cost
approximately $180 million, consists of approximately 108 miles of extra-high-
voltage 345-kV double-circuit transmission, and is targeted to be in-service
by year-end 2014. MidAmerican Transmission is partnering with Westar Energy
and AEP in this venture.
In 2012, MidAmerican Transmission’s Canadian development affiliate entered
into a joint venture with Renewable Energy Systems Canada Inc. in Ontario,
Canada, to sponsor a competitive proposal for the province’s East-West Tie
