Strategic Insights

— 2 min read

Between September 1 and September 7, 2025, a series of baseflow deviations occurred at the RG&E Station 2 and 26 Hydro Projects due to low flows in the Genesee River and NYSCC's attempts to maintain canal levels. The deviations resulted in reduced baseflow rates, with some instances lasting up to 20 hours and 14 minutes. The Station 2 Project, operated by Rochester Gas & Electric Corporation, was offline during the deviation events, and the company reported no adverse environmental conditions or public inquiries. Similar deviations occurred at the Station 26 Project, with baseflow rates hovering around the minimum during the period.

Key Takeaways:

  • Between September 1 and September 7, 2025, a total of 9 baseflow deviations occurred at the RG&E Station 2 Project, with durations ranging from 6 hours to 20 hours, 14 minutes.
  • The minimum recorded baseflow rate during the deviation period at the Station 2 Project was 318 cfs on September 1, 2025.
  • The Station 26 Project experienced too numerous and too short baseflow deviations between September 1 and September 7, 2025.
  • Most durations of the baseflow deviations at the Station 26 Project lasted 15 minutes or less.
  • The minimum recorded baseflow rate during the deviation period at the Station 26 Project was 255 cfs.
  • Both projects were offline during the deviation events, and no adverse environmental conditions or public inquiries were reported.
  • RG&E has confirmed that the deviations were caused by low flows in the Genesee River and NYSCC's attempts to maintain canal levels.

Statistics:

  • Total number of baseflow deviations at the RG&E Station 2 Project: 9
  • Total duration of baseflow deviations at the RG&E Station 2 Project: 72 hours, 32 minutes
  • Minimum recorded baseflow rate at the RG&E Station 2 Project: 318 cfs
  • Total number of baseflow deviations at the RG&E Station 26 Project: too numerous to list
