The insured has coverage for Business Income and Extra Expense under form CP 00 30 10 12 and Causes of Loss- Special Form CP 10 30 10 12 endorsed with the Utility Services-Time Element CP 15 45 09 17 with power supply including overhead transmission lines coverage.

A windstorm causes damage to overhead transmission lines/ power supply causing loss of power to the described premises. The insured had a generator so in order to avoid suspension of the operation, it incurred diesel expenses for the generator to supply power to the premises.

Are these diesel expenses incurred by the insured to avoid suspension of the operation fully covered under the Extra Expense coverage without being subject to any offset or deduction?
