Project and Operational Highlights

Project Highlights


Appel Controls Upgrade ECI Project Saves $75,000 and 220 Tons CO2 Annually

$75,000 and 220 tons/per year carbon equivalent are saved annually with Appel Controls Upgrade


Restored turbines to churn once more

Crews used a heavy crane May 12 to lift the second reconditioned Ossberger crossflow turbine into Cornells Hydroelectric Plant in Fall Creek gorge. The plant generates 2 percent of the universitys electricity.


New LED lights illuminate sports venues vibrancy

The Department of Athletics and Physical Education has begun to install new LED lights at all campus athletic facilities. The project annually will save more than 1.7 million kilowatt hours of electricity, which reduces utility bills by about $136,000 and is estimated to prevent about 450 tons of carbon dioxide annually!

2015 Energy Fast Facts are now available!

The Energy Fast Facts provide a great 1-page snapshot of the present energy production, consumption, emissions associated with the central energy plants (this term includes heating, electricity, and chilled water).


Cornell Snyder Road Solar Farm to produce approx. 2.5 million kilowatt-hours annually

Cornells first megawatt scale renewable electric energy generation project since 1904, the Cornell Snyder Road Solar Farm is a 2MWdc array on Cornell property in the Town of Lansing. It was completed in September 2014 and is expected to reduce the universitys annual GHG emissions by 650 metric tons per year.

New boilers create greater steam efficiency!

Two new boilers were moved in, one August 20, and the second Sept. 2, to provide reliability to heat the campus in the coldest hours of winter should the campus experience maintenance or gas fuel interruptions.


Ewes' chews keep solar farm in tip-top shape

A flock of about 40 sheep (composed of ewes and gelded males) from Scotts farm were delivered to the solar facility July 17  to cut the grass.


2014 Joint Annual Water Quality Report

Every year, a water quality report is prepared based upon the past year's activities. We take great pride in the work that we do and we invite you to read these very informative reports. Cornell collaborates with the other two water purveyors in the Ithaca area to produce this report (City of Ithaca and the Bolton Point Water System).
