This event briefing is designed to review the modelled losses due to wind and storm surge due to TC Tammy, calculated by CCRIF’s Public Utilities model, which covers transmission and distribution lines for electric utilities. The Anguilla Electricity Company (ANGLEC) and the Saint Lucia Electricity Company (LUCELEC) were the only utilities with a CCRIF Public Utilities policy for which the CCRIF Public Utilities loss model reported wind speeds greater than 39 mph (62.7 km/h) due to Tammy.
