Edison is expected to "serve testimony, with supporting data" on the alternative routes or by Jan. 10, according to the PUC.
Edison is in the process of installing larger power towers
along its right of way through Chino Hills to carry wind-generated
electricity from Kern County into the region. The $2.1 billion Tehachapi
project is part of a state mandate to generate more sustainable energy.
It is slated to be completed in 2015.
The PUC's ruling Thursday orders Edison to halt construction until the January hearing.
"Once the Commission reviews the responses to the Petition for
Modifications and the served information, the assigned Administrative
Law Judge and I will determine the next procedural steps and schedule
and inform the parties," said PUC President Michael Peevey in the ruling
order.
