Damage assessment of Puerto Rico's electric system after Hurricane Maria

PA Consulting Group has performed an independent visual damage assessment of the Puerto Rico electric system to understand the extent of the damage to the system caused by Hurricane Maria. The assessment is comprised of a comprehensive helicopter and ground-based review of all 230kV transmission corridors, a ground patrol of 225 distribution circuits island wide, based on a statistical sampling design, and a visual assessment of the physical condition and operational status of PREPA’s generating plants.

Initial news reports suggested 85% of the system was destroyed at a cost of US $5B to replace, while our observations and preliminary analysis indicates that the reverse is true: substantially more than 85% of the system’s assets survived the hurricane intact, and service could be restored to pre-hurricane levels at a cost likely below US $1B.

Assessment was conducted on behalf of Ad Hoc PREPA Bond Holder Group.

Below are links to photographic evidence of the condition of specific portions of PREPA’s electric system:
