Inspections cover turbines, transformers, switchgear, cabling, grounding systems, and control equipment. Detailed inspection reports must be submitted to the DEQ and PSC as part of compliance documentation.
  • Strict Lockout/Tagout (LOTO) Procedures: To prevent accidental energization during maintenance or repair, wind farms must implement rigorous lockout/tagout protocols. These procedures require isolating electrical energy sources and clearly labeling equipment as de-energized, ensuring worker safety during potentially hazardous tasks.
  • Comprehensive Emergency Response Plans: Operators are required to develop and maintain emergency response plans specifically addressing electrical accidents, fires, and other related incidents. These plans include immediate response actions, notification protocols, coordination with local emergency services, and post-incident investigations to prevent recurrence.

Safety Standards for Electrical Equipment and Installation Practices

Montana regulations place strong emphasis on the quality and safety of electrical equipment used in wind farms. All electrical components—such as transformers, switchgear, circuit breakers, and grounding systems—must meet or exceed recognized industry safety standards, including those established by Underwriters Laboratories (UL), the Institute of Electrical and Electronics Engineers (IEEE), and the International Electrotechnical Commission (IEC).

Installation practices are also tightly regulated to prevent electrical faults that could cause outages, equipment damage, or safety hazards. Contractors must follow manufacturer specifications closely and comply with national and state electrical codes during equipment installation. Particular attention is given to:

  • Proper grounding and bonding to mitigate the risk of electric shock and lightning damage.
