CHINO HILLS – Southern California Edison has been ordered to investigate another underground power-line route for the power lines due to carry 500 kilovolts of wind-generated electricity through the city.

Earlier this month, Edison turned over a 96-page document to the state Public Utility Commission that detailed “feasibility, cost and timing” on 16 possible options for building the high-voltage Tehachapi Renewable Transmission Project through Chino Hills.

Transmission poles and towers are being built in Edison’s right of way through a 5-mile stretch of Chino Hills to meet the state’s mandate to generate more sustainable energy.

The $2.1 billion power line project is intended to bring wind-generated electricity from Kern County to the Los Angeles Basin.

Chino Hills officials have spent $2.4 million in battling Edison in a lawsuit for two years insisting that its right-of-way through the city is too narrow for the 200-foot power towers.

After reviewing Edison’s documents, city officials concurred it was incomplete and requested the commission send Edison back to do further analysis on a single-circuit underground scenario, City Manager Mike Fleager said.

All of Edison’s studies for undergrounding have been double circuit lines, none of their studies were for single circuit because it wasn’t required, Councilman Ed Graham said.

After identifying this, and that there is a potential for it to be cheaper, the city submitted a letter to the commission on Jan. 16 requesting a report be done on a single-circuit 500-kilovolt line underground, Fleager said.
