Swiss Re's solar power installation at its U.S. headquarters in Armonk, N.Y., a 2-megawatt facility expected to be up and running by late spring 2017, is just one part of a green theme that the carrier has been writing for itself over several years. Work began in October on the power plant, which will occupy roughly 10 acres of land on Swiss Re's property.

When completed in late spring 2017, the solar plant will occupy 10 acres of space in the Southeast corner of Swiss Re's U.S. headquarters campus in Armonk, New York. More than 7,700 individual solar panels will provide 2 megawatts of power generation, making it the largest installation of its type permitted in the state of New York.
