(b) Subject to any applicable tariff provision, in an action for damages resulting from a wildfire ignited or propagated by an electric utility's, municipally owned utility's, or electric cooperative's facility, the utility or cooperative is not liable for damages resulting from the wildfire if the trier of fact in the action finds that the utility or cooperative:
