Large scale project off Morro Bay may be decade off
-June 8,2021-
The wind blows steady off Vandenberg Space Force Base, the new name for the Air Force facility, just announced. While the public’s focus has been on the potential for a space exploration industry growing here, the area’s oceanfront will also play a role in the rollout of the West Coast offshore wind industry and likely sooner than you think.
For the past two years, 2 European firms have been vying to build the first offshore wind turbines in California on a demonstration basis.
It is here we will most probably see the region’s offshore wind turbines deployed with construction starting in the first quarter of 2023 and producing power for Vandenberg as soon as 2024.
That is the schedule being proposed by one of the two wind power companies – Cierco, proposing to erect four 800-ft wind turbines that will produce 60 megawatts of power in state waters, less than 3 miles out – off Point Arguello.
Cierco, with offices in Scotland, is considered to be ahead in the competition with a fully detailed plan filed with the state Lands Commission as of last July, ahead of their competitor, France-based Ideol. Ideol has yet to finalize their application to the state body who will lease the seabed.
Staff at the commission says Cierco could begin the formal EIR process of their project, launching this October.
The energy project may be small compared to the more publicized Morro Bay offshore wind project proposed some 30 miles off the Cambria coast in federal waters that would deploy 100 wind turbines producing 1000MW.
The project, stalled for years by US Navy objections, is now on the front burner with the Biden administration who a few weeks ago announced all its agencies including the Dept of Defense are now behind the project – looking to boost renewable energy to fight global warming. Biden tag-teamed with California Governor Newsom designating 399 square miles of ocean off the coast of Morro Bay that will be open for offshore wind projects.
The area to be auctioned off to developers in three sections has the potential to power 1.6 million homes. Unlike the Vandenberg project where the wind turbines would be anchored to the seabed in relatively shallow state waters, the Morro Bay project would deploy floating wind turbines in 2600 to 3600 feet water depth using what is technology where experience is limited worldwide.
Despite hopes to speed the implementation of California offshore wind energy that clearly – be could be a game changer, complexities of the technology, planning and permitting and the need to bring all stakeholders to the table could make for a long wait for guys who say they are in hurry to save the planet.
With all the press releases recently, estimates of how long it will take to see Morro Bay wind power happen are sobering. The Biden administration says their BOEM agency could lease waters off Morro Bay – but not off Diablo Canyon – as soon as next year. The auction could be lively with 14 developers so far looking to make bids. The company who has done the most groundwork is Castle Winds who has a memo of understanding with the City of Morro Bay and with local fishermen.
What about Diablo waters?
Despite the impending closure of Diablo Canyon, and toned to replace 2000MW of generation -there is no official move to lease waters off this part of the Coast despite plans to retain the grid connection infrastructure that connects to state transmission lines. Announcing a potential wind power auction here too would make sense sooner than later.
Decade off?
Castle Wind CEO Ala Weinstein expects the even after auction results are settled it will still be perhaps 7 years to go through the planning and permitting issues with an extended construction period to follow.
“You’re probably looking at a decade from next year”- 2032- “until the electrons from offshore wind units will go into the grid,” Weinstein recently told the press.
Up to 7000MW?
Despite the wait,CalPoly’s Reach program recently suggested an expanded “call area” the could be leased that would house up 7,000MW of wind farms off the coast of Morro Bay/perhaps including Diablo offshore area that could generate up to 1,469 good-paying jobs and $707 million in annual economic impact across the two counties.
They said construction of a specialized wind port would bring its own benefits, according to the Cal Poly study, including a $412 million annual economic impact to SLO and Santa Barbara Counties and 2,411 annual jobs over the 5-year project.
Although the Central Coast will probably not house a major construction port for offshore wind- it could host a smaller operation that handles maintenance of turbines and shuttles workers out to to the job site – a local working port such as Port San Luis, suggest some.
Walk before you run?
Supporters of the Vandenberg demonstration project say a pilot project completed and in operation for a while years before the large-scale mega-project is built – makes sense, helping to avoid what could be costly mistakes.
In their filing with the state, Cierco says their project –
– Provides an opportunity to understand the required environmental and administrative processes on a “small” scale development.
– Diversifies the floating wind technology offering for offshore wind in California.
– Reduce risk for offshore wind in advance of the BOEM competitive offshore wind leasing round in California.
– Provide an opportunity for the local supply chain, infrastructure and workforce to build the necessary investment, capacity and learning at a manageable rate in advance of large scale deployment
-Provide an opportunity for the DoD to develop a familiarity of operational interaction with the technology at a scaled level prior to large scale deployment.
Power at their doorstep
Not well appreciated is the importance of Vandenberg’s energy situation including the need for onsite power redundancy and resiliency of this vital military base providing 60 MW of 24 hr power coming ashore by an existing cable to Vandenberg for local use. Already the base relies on its new solar farm for 35% of the base’s power needs. But the sun does not shine for half of that.
With grid uncertainty in the near future amid epic droughts and wildfires grid blackouts, the base’s long-term security seems to require the constancy of wind power as well as energy storage at their doorstep.
Wind speeds off of Pt Arguello and Pt Conception are more impressive than off Morro Bay and expansion in the number of turbines in this sector could happen here too, far beyond these first pilot projects.
