Series I, Files from the Office of the President, spans the years 1956-1977 and includes files that were kept by PP&L president, Jack K. Busby. Topics included in this series span a wide variety of topics over a span of just over two decades. Of particular note are files of correspondence regarding coal transportation with the Penn Central Company, as well as files on utility taxes and rates, the Keystone Power Plant Project, reports and correspondence on the Advisory Committee of Reliability of Electric Bulk Power Supply of the Federal Power Commission, and finally files on the Northeast Blackout of November 1965 which resulted in the failure of the power grid in much of PP&L's service region.
