PREPA bondholders dispute damages to Puerto Rico's power grid

Read the full CNBC article here.

Derek HasBrouck, energy and utility expert at PA Consulting Group, shares an analysis of the damages of the Puerto Rican electrical grid after Hurricane Maria. His observations were included in a legal filing by the Ad Hoc Group of PREPA bondholders.

Derek's preliminary analysis notes that Puerto Rico's utility grid is largely intact, with 95 percent of transmission assets and the vast majority of the distribution system mainly unscathed. Additionally, it said the generation units that were operational prior to Hurricane Maria are in "serviceable condition."

Derek’s team also conducted a damage assessment which was conducted aerially via a two-day helicopter review and supplemented by ground visits. The PA team "visually evaluated all generation plants on the island, all 230 kV transmission corridors (including substations) as well as the 115 kV transmission lines co-located in these corridors, and a statistically meaningful sample of distribution circuits."
