Regulators halt construction on Chino Hills transmission line

California state regulators have halted construction on a controversial transmission line in Chino Hills.

A new order from the California Public Utilities Commission also directs Southern California Edison to consider alternative routes for the project known as the Tehachapi Renewable Transmission Project.

The PUC approved the project two years ago, but the city of Chino Hills and its residents oppose it. A group called Hope for the Hills claims the line runs too close to homes. Chino Hills even paid for studies to provide alternatives and some of those will now be looked at.

It's unusual for regulators to block a project they've allowed to get this far. Poles and 200-foot-tall towers are already in the ground. Regulators will consider the other alternatives early next year.
