Southern California Edison this week released its report of alternative power line routes in the area of Chino Hills estimating costs of about $175 million to more than $1 billion if the project is changed by the state Public Utilities Commission.
The amount would surpass the current projected cost of building the Tehachapi Renewable Transmission Project by at least $8 million.
The document released late Tuesday by Edison was ordered by the state Public Utilities Commission to provide data on the various alternatives for the expanded power lines:
Through Chino Hills State Park
Undergrounding the power lines through the city
A different route through the city and/or state park
Using the existing right-of-way but with shorter, more closely spaced towers
Ways to reduce the impact of larger towers
The PUC made the request for the report two months ago. At the same time the commission required Edison to halt construction on its Tehachapi project through Chino Hills.
Officials of Edison said the approved route for the Tehachapi project that has already begun was considered in a comprehensive review by the commission in 2009 that largely focused on the proper route in the Chino Hills area.
“If a decision is made to move the lines from our existing right-of-way in Chino Hills, the determination of cost responsibility for changes to the project, if any, will be made by regulators at a future date,” said Paul Klein, Edison spokesman.
The high-voltage transmission poles and towers are being built to meet the state’s mandate to generate more sustainable energy and is expected to be complete in three years.
According to the report, if the project stayed on its original course the total cost will be $166 million.
The alternative of having shorter towers was the second least costly option, ranging from $174 million to $192 million.
If the project went around the city and through land of the state park, the cost would be anywhere from $424 million to $589 million.
