What insurance do I need for temporary generator and power work at tower sites?

Temporary generator and power work at tower sites introduces exposures beyond standard tower contractor coverage. Required considerations include: (1) Pollution liability for fuel storage, handling, and potential spills. Diesel generators require fuel delivery and on-site storage, creating environmental liability. Even small spills on tower sites in environmentally sensitive areas (wetlands, near waterways) can create costly remediation obligations. (2) Property damage coverage for the generator equipment itself (inland marine) and for damage the generator could cause to site equipment (voltage spikes, improper power conditioning damaging carrier electronics). (3) Electrical work exposure under your GL, as connecting generators to tower equipment involves energized electrical work. Some GL policies exclude electrical contractor operations. (4) Business interruption exposure: if your generator fails or causes damage that takes the cell site offline, the carrier may have business interruption claims from loss of service. (5) Fire liability: generators and fuel storage create fire risk at sites often located in rural or wildland interface areas. A fire spreading from a tower site can create catastrophic property and environmental damage. Professional liability may also apply if you provide power system design or load calculations. Confirm your GL does not exclude operations involving petroleum products, electrical work, or fire-related claims at these sites.
