Transmission Outages in ISO-NE & NYISO Will Elevate Congestion Risk This August | Congestion Watch Blog
Published July 14, 2021 | congestion-watch
Weather forecasts across the Northeast power markets continue to call for warmer-than-normal temperatures this summer and elevated electricity demand will be the main congestion driver in August. Planned generator maintenance will be minimal; however, forced generator outages during hot summer weather could significantly impact congestion and be an import constraint on areas across the Northeast Power Pools.
- ISO-New England – Transmission outages will elevate the congestion potential in NEMA, SEMA, and CT.
- PJM – In Mid-Atlantic there is minimal transmission work scheduled, although 765 kV line work in Western PJM will be bullish for AEP, and 345 kV outages will be bullish for ATSI.
- NYISO – Transmission outages continue to impact the Central-East interface throughout August, increasing the congestion potential in Zone F. Transmission work is also expected to be bullish for Zone A congestion.
