It\u2019s Cornell\u2019s very own <a href=\"https:\/\/fcs.cornell.edu\/departments\/energy-sustainability\/utilities\/hydroelectric-plant\" target=\"_blank\" rel=\"noopener noreferrer\">hydroelectric plant<\/a>. And despite its unassuming appearance, it packs a punch\u2014in fact, it generates 3 to 5 percent of the Hill\u2019s electricity each year. <\/p>\n\n\n\n<p>It\u2019s also the oldest component of the University\u2019s ongoing commitment to renewable energy\u2014an effort that also includes <a href=\"https:\/\/sustainablecampus.cornell.edu\/buildings-energy\/solar-energy\" target=\"_blank\" rel=\"noopener noreferrer\">solar arrays<\/a>, <a href=\"https:\/\/fcs.cornell.edu\/departments\/energy-sustainability\/utilities\/cooling-home\/cooling-production-home\/lake-source-cooling\" target=\"_blank\" rel=\"noopener noreferrer\">Lake Source Cooling<\/a>, and the proposed <a href=\"https:\/\/earthsourceheat.cornell.edu\/\" target=\"_blank\" rel=\"noopener noreferrer\">Earth Source Heat<\/a> system.<\/p>\n\n\n\n<p>First, one key fact: the hydroelectric plant is not to be confused with the Hydraulic Laboratory. <\/p>\n\n\n\n<p>That venerable research facility, formerly visible from the Thurston Avenue Bridge, was on Fall Creek Gorge\u2019s south side; it was state of the art when it opened in 1898, but stood empty for decades before collapsing into the gorge in 2009. <\/p>\n\n\n\n<p>The hydro plant is fueled by water from Beebe Lake, which flows through a trash-clearing mechanism and through the intake house, a roofed structure with a wooden gate. <\/p>\n\n\n\n<p>Then it enters a 1,700-foot concrete pipeline (called a \u201cpenstock\u201d)<strong> <\/strong>plunging 140 feet into the gorge, through the power-producing turbines inside the plant, and back into the creek. <\/p>\n\n\n\n<figure class=\"wp-block-image alignwide size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\"
