Subestación Caguanas - 38 kV Substation in Puerto Rico, United States

Subestación Caguanas is a substation located in Puerto Rico, United States, owned and operated by the Puerto Rico Electric Power Authority (PREPA). As a 38 kV substation, it plays a role in the island's electrical infrastructure, stepping down voltage for distribution to local consumers. The facility operates under the regulatory framework of the United States, including NERC reliability standards and FERC oversight for transmission-level assets. While 38 kV is considered a sub-transmission or distribution voltage, it is critical for grid stability in Puerto Rico, where the electrical system has faced challenges from extreme weather events and aging infrastructure. As part of PREPA's network, Subestación Caguanas contributes to the reliability of electricity supply in the region. Its operational status ensures continued service to surrounding communities, supporting residential, commercial, and industrial activities in the area.

The substation is located in a tropical climate zone, where hurricanes and storms pose risks to electrical infrastructure. Its urban or rural setting influences exposure to vegetation and weather-related disruptions. The 38 kV voltage level indicates a distribution role, with potential environmental impacts limited to localized electromagnetic fields and land use.
