Intensive livestock systems are critically dependent on electricity for ventilation, feeding, and temperature control, making power outages acute welfare emergencies for confined animals.
The complete dependency of intensive livestock systems on continuous power creates a welfare vulnerability that periodic grid failures can turn catastrophic. Tens or hundreds of thousands of animals can die from heat, cold, or asphyxiation within hours when ventilation, heating, or cooling systems fail. Regulatory requirements for generator backup, ventilation failure alarms, and emergency response protocols are the primary mitigation measures. The welfare case for backup power requirements is clear and the cost per animal protected is relatively modest compared to the catastrophic welfare events that occur without them.
