As part of his work organizing the initial materials recovered from the Autoridad de Energia Electrica de Puerto Rico, AGPR archivist Juan Roman identified this rare 1939 map of Puerto Rico’s hydroelectric projects. It will be featured as the document of the week in the AGPR’s publications, with a proper digital version. It forms part of the “archivo vertical” of the Autoridad which he is organizing. The rest of the AEEPR archive will soon be part of the AGPR holdings.
