Greater Rochester International Airport (GRIA) is located four miles southwest of Rochester, NY on the west side of the city and operated by Monroe County. The terminal totals 380,000 sq. ft., with 22 passenger gates. The county strives to maximize the benefits it provides local taxpayers. Reducing energy costs is one of many ways the county seeks to fulfill that goal. At GRIA this was achieved by installing two 750 kW engine-generators that produce about 90% of the site’s electricity.
