For the most part, the cable bundle will be installed under the Columbia River over the course of a few months, taking extreme care not to disturb sensitive river habitats or existing river uses. Between the river and the interconnection points at The Dalles and Portland, there will be short stretches of cable buried underground. In addition, the cable bundle will exit the river for about 7.5 miles to bypass the Bonneville Dam. https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/43c10e5c-9652-4d3e-af97-d6b069a2957d/Plow+description.jpg Description The underwater cable will be installed using established, benign hydroplow technology of the type used for numerous underwater installations around the world. As shown on the figure, the cables are fed from a ship or barge into the blade of the hydroplow which is towed by the installation vessel. High-pressure water jets fluidize the river bottom sediment, creating a narrow (approximately 24 inch) trench for the cable bundle. As the plow moves forward, the cable bundle settles into the trench at the prescribed depth and the fluidized sediment settles back over the bundle to fill the trench. https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/1603119611193-2D8P0HQM7GW0LVJE6FQW/trans%2Bbay%2Bconverter.jpg Description The Project will feature Voltage Sourced Converter-High Voltage Direct Current (VSC-HVDC) technology, characterized by controllability, compact design, and ease of interface with interconnecting systems. A converter station will be built at both ends of the line, adjacent to existing substations, and similar to these substations in overall appearance. The technology for Cascade will be comparable to that used for the Trans Bay Cable Project in San Francisco (photo on left), which has been reliably operating and meeting approximately 40% of the greater San Francisco area’s power needs since 2010. https://www.cascaderenewable.com/project/in-depth daily 0.75 2024-09-26 https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/3e21aae8-1b4f-42ee-a3b9-018dda169df1/thumbnail+project+1+pgr+rev.jpg In Depth Project Overview https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/15706697-4fa5-4691-895f-dd57f1c0f3d0/PNUCC+thumbnail.jpg In Depth PNUCC Forecasts 30% Demand Growth for Pacific Northwest https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/cc6cbefe-ea8b-48d8-b572-bdc9dca28ffe/thumb_Energy+GPS+cover.jpg In Depth Cascade Renewable Economic Study https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/3c4f7f45-6be8-4fe3-a970-6e937399b8d7/_thumbnail_CRT_PGE+IRP+Comments+11.21.23.png In Depth Cascade Renewable Transmission Files Comments with OR PUC on PGE IRP https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/4227572d-f965-4d3e-8c17-7a534845813a/Wyden+ltr+thumbnail.jpg In Depth Senator Wyden Urges Coordination to Meet Energy Needs https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/01bd61f9-26b0-4017-b4e3-e5cb7bf9b776/thumb_TCWG+Report+cover+image.jpg In Depth Washington Transmission Corridors Work Group Final Report https://www.cascaderenewable.com/team/team daily 0.75 2026-01-14 https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/1602525361568-SVI3PGZPAM57C04U69GS/PowerBridge_logo_RGB.gif Team https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/1602525418316-EJP7IMJQBBCY5ZMZA5KP/Sun2o+Partners+%281%29_Crop.png Team need high Sun2o logo https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/31d45d65-f2e9-46e2-9f38-454695cc10ed/updated+nextera+logo.png Team - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://www.cascaderenewable.com/team/experience daily 0.75 2020-10-28 https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/1602095782240-7N6A89DU9XSOCTLX1DP9/Sayreville+Fac+3.jpg Experience Neptune Converter Station - Sayreville, NJ https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/1603307518186-P6YXNTFBTZ3CBOPP5PGU/GV%2Bnyc%2Bskyline%2BJan%2B2012.jpg Experience The cable lay vessel exits New York harbor after the marine cable installation in 2012. https://www.cascaderenewable.com/faq daily 0.75 2026-01-06 https://www.cascaderenewable.com/contact-us daily 0.75 2020-10-28 https://www.cascaderenewable.com/home daily 1.0 2025-03-31 https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/1602097706494-328DI31S6Q7NVZMGDC97/stock+wind Home - Project Description The Cascade Project consists of an electric transmission cable bundle, which will be buried entirely underground and underwater, and two converter stations, which will be located adjacent to existing substations. The Project can transfer approximately 1,100 MW of utility-scale wind, solar, and other renewables to help meet renewable energy demand in Oregon and Washington. The Project starts in The Dalles, Oregon and travels approximately 100 miles, mostly beneath the Columbia River to the Portland area. https://images.squarespace-cdn.com/content/v1/5f58d09900db195b4ed592ad/1602095251622-KXI55MGSGWSLI2660G54/Neptune+Duffy+Converter.JPG Home - The Development Team Cascade Renewable Transmission, LLC, the principal developer of the Project, is an affiliate of PowerBridge, LLC of Fairfield, Connecticut.
