US authorities proposes 10 ‘nationwide curiosity’ transmission corridors – pv journal International


Eight of the ten transmission corridors proposed by the US Department of Energy (DoE) may facilitate transmission between grid areas. One will broaden transmission inside the Mid-Atlantic’s PJM grid area, and the opposite will broaden transmission within the Northern Plains.

From pv journal USA

The US DoE has proposed 10 National Interest Electric Transmission Corridors (NIETC), as proven within the featured picture above, and is accepting public touch upon potential NIETCs.

The DoE had beforehand sought business enter for the primary stage of the NIETC designation course of.

A NIETC designation, as soon as once more, “opens up” federal financing and permits instruments to encourage the development of transmission tasks “to alleviate hurt to customers,” the DoE stated. Such damages might end result from transmission capability limitations or congestion “now or sooner or later,” and will manifest as decrease reliability or larger prices.

If transmission is congested, for instance, some lower-cost renewable energy have to be intercepted as an alternative of delivered to prospects.

In phrases of transmission financing, a NIETC designation may open up public-private partnerships by way of the Bipartisan Infrastructure Law’s $2.5 billion Transmission Facilitation Program, in addition to direct loans by way of the US Inflation Reduction Act’s $2 billion Transmission Facility Financing Program.

A NIETC designation additionally permits the US Federal Energy Regulatory Commission to problem permits for the position of transmission strains inside the NIETC when sitting state authorities wouldn’t have line placement authority, or didn’t act on an software for greater than a 12 months, or refused an software.

The DoE introduced in a report preliminary findings of transmission capability limitations or congestion inside every of the ten geographic areas it proposed for NIETCs. The streamlined generator interconnection is among the anticipated advantages of transmission improvement because of the NIETC designation, stated the DoE.

One of the DoE’s 10 proposed NIETCs will broaden transmission inside the PJM grid area within the Mid-Atlantic, serving to the PJM grid operator preserve and enhance reliability, decrease prices for customers, and meet future technology and demand. -growth in demand.

Another proposed NIETC within the Northern Plains will particularly assist Native American tribes develop vitality assets, stabilize vitality prices and encourage native financial improvement.

Those two proposed NIETCs replicate a discovering within the DoE’s National Transmission Needs Study that 54,500 GW-miles of intra-regional transmission have to be added for a clear grid underneath the “almost certainly future electrical energy sector. “

Eight out of 10 proposed NIETCs will facilitate transmission between grid areas, which exhibits in a wants examine that interregional transmission capacities to transmit electrical energy between areas ought to enhance to nearly 125 GW underneath the possible future energy sector.

Here are the eight proposed NIETCs and the areas they may hook up with:

  • The New York-New England NIETC will enhance transmission capability between the New York and New England areas of the grid.
  • The New York-Mid-Atlantic NIETC will enhance transmission capability between the New York and PJM grid areas and facilitate the interconnection of offshore wind.
  • A Mid-Atlantic-Canada NIETC will join the PJM grid area to a Canadian grid area.
  • The Midwest-Plains NIETC will facilitate interregional transmission within the PJM, MISO, and SPP grid areas.
  • The Delta-Plains NIETC will enhance transmission between the SPP and MISO grid areas, and doubtlessly join the Eastern and Western Interconnections.
  • The Plains-Southwest NIETC will facilitate transmission within the WestConnect, SPP, MISO, and PJM grid areas, and doubtlessly the CAISO grid area.
  • A Mountain-Plains-Southwest NIETC will hyperlink the Eastern and Western Interconnections and doubtlessly facilitate transmission between the WestConnect and SPP grid areas.
  • Mountain-Northwest NIETC facilitates interregional transmission between CAISO and NorthernGrid areas.

The DoE will current a webinar on the present part of the NIETC appointment course of on May 16.

The DoE beforehand stated it expects to reopen the NIETC designation course of after every publication of its three-year National Transmission Needs Study or as decided by the Secretary of Energy.
