WHITE PLAINS – The New York Power Authority (NYPA) recently launched the application of new state‑of‑the‑art 3D modeling software at its Gregory B. Jarvis small hydroelectric plant on the Hinckley Reservoir in Oneida County to help the power dam withstand extreme weather events. The new software – FLOW 3D – will allow NYPA engineers to harness powerful advances in 3D computer modeling on behalf of the Hinckley dam and continue to ensure maximum safety and peak performance.


“At NYPA, our engineers are leading the way by using advanced, cutting‑edge software to ensure the safe and reliable operation of our facilities, even under the most extreme environmental conditions,” said Gil C. Quinones, NYPA president and CEO.


Flow Science’s FLOW‑3D software, the latest in computational fluid dynamics software, helps predict where water will flow and allows NYPA engineers to model the worst possible rainfall and flooding conditions for the region and predict how Hinckley Dam will perform. Use of the software is expected to be rolled out to other NYPA sites in the coming months.


FLOW‑3D draws a far more accurate picture of fluid interaction with the dam’s structure than was possible using older software. It accounts for a vast range of factors, including upstream and downstream water levels, surface roughness and various water pressure profiles. It took NYPA engineers several months of calculations and verification using a multidisciplinary approach to produce an accurate model of the flows and forces during maximum flood conditions.


The analysis will allow NYPA to make targeted modifications to the facility if necessary. This approach saves time and cost, and avoids disruptions to service in surrounding communities and with recreational use of the reservoir, which is a popular local boating and fishing spot.


By developing expertise in the use of advanced software, NYPA engineering is supporting Governor Andrew M. Cuomo’s Reforming the Energy Vision strategy to improve the state’s energy infrastructure by ensuring the safe, efficient and cost‑effective operation and maintenance of NYPA’s assets and is consistent with NYPA’s goal of becoming the first end-to-end digital utility in the country.
