Transmission upgrades that are needed to avoid overloads in a fully electrified New England by 2050 could cumulatively cost between $22 billion and $26 billion, ISO-NE told its Planning Advisory Committee.

ISO-NE expects system emissions to fall by nearly half by 2032 as gas generation declines, but projects coal and oil generation to increase to cover winter peak loads.

ISO-NE told its Planning Advisory Committee that decarbonization may require increased dispatchable generation, storage and capacity.

NESCOE pressed transmission owners to increase the transparency of their asset condition projects and incorporate them into ISO-NE’s planning process.

ISO-NE is studying line upgrades and new 345-kV and HVDC lines to address expected reliability violations in its 2050 Transmission Study.

The preliminary results of ISO-NE’s 2050 Transmission Study suggests that New England will need to build new transmission and shift existing resources.

ISO-NE presented to the PAC its scope of work and modeling assumptions for its 2050 Transmission Study.

The ISO-NE PAC received a project list update for the Regional System Plan that included 12 new projects to resolve thermal overloads and voltage violations.

ISO-NE is proposing a pilot study to analyze the potential curtailments experienced by new generation from the addition of offshore wind on Cape Cod.
