The Federal Energy Regulatory Commission’s Energy Infrastructure Update for May 2019 includes predictions for proposed hydro generation additions and retirements by June 2022.
They are: Addition of 217 units for a total installed capacity of 14,608 MW. In the category it calls “high probability additions,” FERC says 84 units will be added for total installed capacity of 1,909 MW. For hydro retirements, FERC anticipates 19 units and total installed capacity of 526 MW by June 2022.
In total, across all generating technologies, this FERC report predicts:
- All additions: 3,743 units for total installed capacity of 269,018 MW
- High probability additions: 953 units with total installed capacity of 75,528 MW
- Retirements: 248 units for total installed capacity of 37,517 MW.
The report says the single largest capacity addition by June 2022 will come from wind, at 99,037 MW. However, for high probability additions, the largest growth comes from natural gas, at 28,263 MW. And the category with the highest retirements is coal, at 17,054 MW.
The only hydropower activity occurring in May 2019 was a 3.64-MW capacity addition to NorthWestern Corporation’s Missouri-Madison Project, increasing to 308.88 MW.
Earlier this month, HydroWorld reported that FERC issued a preliminary permit for the 5.5-MW Hamilton Low Dam Hydroelectric Project in Ohio.
