sliced offshore wind costs<\/a>.<\/p>\nThe Coos Bay site has an average wind speed of 9.8 metres per second (m\/s), the highest in the study, making it the favourite for many developers.<\/p>\n
\u201cI’d say that (Coos Bay) is the preferred site,” Jason Busch, Executive Director at Pacific Ocean Energy Trust (POET), a non-profit think tank which promotes responsible marine development, told New Energy Update.<\/p>\n
“There\u2019s high amount of wind resource which could accommodate tens of gigawatts of the highest quality power,” he said.<\/p>\n
\u201cOffshore floating wind is ready for primetime,” Jim Lanard, co-founder of Magellan Wind, a developer of offshore projects in California, said.<\/p>\n
“That\u2019s the approach we\u2019re taking in California and now we\u2019re moving in to Oregon because of a lot of interest we\u2019re seeing in Coos Bay.”<\/p>\n
A number of challenges in Oregon must yet be overcome, experts warned.<\/p>\n
Coastal transmission infrastructure would need to be upgraded and a wide range of stakeholders must be consulted before sites are allocated.<\/p>\n
New connections<\/strong><\/p>\nOregon’s Renewable Portfolio Standard (RPS), implemented in 2016, requires investor-owned utilities PacifiCorp and Portland Generation Electric (PGE) to supply 50% of their electricity from renewable sources by 2040. PacifiCorp and PGE supply around two thirds of Oregon’s electricity demand and smaller utilities must meet also meet RPS targets, set at lower levels.<\/p>\n
Hydroelectric plants supplied 58% of Oregon’s utility-scale power generation in 2018 while gas-fired generation supplied around 25%, onshore wind 12% and a small portion came from coal-fired plants, according to the U.S. Energy Information Administration (EIA).<\/p>\n
Most of the hydroelectric fleet does not qualify for the RPS, requiring significant wind and solar buildout in the coming years.<\/p>\n

This stretch also benefits from low population levels and relatively few fishing ports, reducing the risk of local opposition, he said.<\/p>\n
Power transmission is a key challenge for development, Busch said. Significant investment would be required in shoreside infrastructure and subsea cabling. Bonneville Power Administration (BPA) owns the largest share of grid infrastructure, with smaller shares held by PacifiCorp and local public utilities.<\/p>\n

If developers are instead required to build individual radial transmission lines, this would incentivize projects closer to the shore, increasing potential conflict with fishing and traffic routes, Busch said.<\/p>\n
“The only way that area gets developed is a backbone line or lines that are connected in both California and Oregon to ensure redundancy and to facilitate a more efficient grid and regional energy markets,” he said.<\/p>\n
Plans underway<\/strong><\/p>\nAs market interest builds, the Bureau of Ocean Energy Management (BOEM) is working with Oregon authorities to initiate a planning process for potential siting opportunities.<\/p>\n
The BOEM must perform comprehensive stakeholder engagement and analysis before it identifies any potential sites, warned Necy Sumait, head of the BOEM\u2019s Pacific Renewable Energy Section.<\/p>\n
Stakeholders include an intergovernmental task force of federal, state and native-American-tribe officials, the Department of Defense, representatives from the commercial fishing industry and environmental groups.<\/p>\n
Developers like Magellan are also working with officials and other stakeholders to build a comprehensive offshore development framework.<\/p>\n
While a tender could be launched in Oregon as soon as 2022, it will take several years before the first facility is online, Lanard said.<\/p>\n
“Once there\u2019s an auction, it\u2019s five to seven years before a project is ready to start providing electricity,\u201d he said.<\/p>\n
