How transmission works

Transmission_NewIllustration_biggernumbers.png

  1. 1

    Electricity is generated.

  2. 2

    Transformer increases voltage of electricity.

  3. 3

    Electricity travels through transmission lines.

  4. 4

    Transformer decreases voltage of electricity.

  5. 5

    Electricity travels through collection lines.

  6. 6

    Electricity is delivered to customers.

Why transmission

High-voltage direct current (HVDC) is ideally suited technology for connecting U.S. grid regions. It cost-effectively moves large quantities of power over long distances. It precisely controls power flows, and it pulls electricity from healthy grids to jumpstart failed grids with “blackstart” capability. Today, Invenergy has 11 gigawatts of new transmission capacity in development—representing roughly one-third of new U.S. HVDC transmission. 

Transmission infrastructure in the U.S. will need significant growth to support the demand for AI as well as to support other rapidly growing sectors of the U.S. economy like new manufacturing and electric vehicle loads.

Cimarron Link
Cimarron Link will unlock access to one of the lowest-cost, steadiest-producing natural energy resources available anywhere in America – the inexhaustible wind energy of Oklahoma’s Panhandle. This project will support energy price competitiveness and stability for Oklahoma families and businesses, bolster reliability by diversifying energy solutions, and strengthen long-term energy security by reducing our reliance on foreign energy.

Cardal Transmission
Invenergy and its subsidiary Tealov developed the Cardal Transmission project, which is helping enable Uruguay's transition to a clean energy future. The project consists of 55 kilometers of new 500 kV high-voltage transmission line, 20 kilometers of new 150 kV transmission line, a new 500 kV substation and accompanying infrastructure. The line connects to the Punta del Tigre substation and a 150 kV high-voltage line in Salto, Uruguay.
