Re: Baseline Study and Monitoring of the tidal current energy project at Race Rocks

Dear Garry:

Our response to your request for baseline inventory and monitoring services for the Race Rocks tidal current project follows. Our response is slightly unorthodox in that I have taken each of your task requirements and provided comment on a proposed approach and, when possible, some idea of scope, effort and cost. We cannot provide an overall cost estimate for this project until we have further defined the monitoring requirements with yourself and the proponents, in particular the approach and degree of effort required for monitoring noise levels on land and in water. In addition there are partnering opportunities with Pearson College which could reduce costs. However, given the scope provided, I think that the overall project budget will be in the $40,000 to $70,000 range, with about 30-40% of costs attributable to noise monitoring.

We are very interested in working with the Person College-EnCana-Clean Current group on this project, both because of our long term appreciation of Race Rocks as a valued and sensitive marine ecological area, as well as our support for innovative and sustainable energy generation. If you have any questions with respect to this response please contact me early next week.

Sincerely

Brian Emmett, M.Sc.

Director, Marine Environmental Services Division

Tide Turns for Power, and for Young Minds: Pearson College, Partners Apply Current ThinkingTimes Colonist (Victoria)

They’re harnessing the tide at Pearson College to keep the lights burning at Race Rocks. Turbulent tides tumbling by Race Rocks ecological reserve near Metchosin will test how well a new tidal turbine generator stands up to the harsh West Coast environment.
Pearson, which brings together students from around the world for studies and to serve the community, expects the tides to help produce more than enough electricity to replace two diesel generators and provide power to the college’s marine education centre on Great Race Rock Island by 2006. “The project, the first of its kind in Canada, could prove the value of new technology over time and it could be very beneficial to coastal peoples around the world,” Stuart Walker, director of Lester B. Pearson College of the Pacific, said Friday. The $4-million project is a partnership between Pearson College, EnCana Corporation of Canada, and Clean Current Power Systems of Vancouver. EnCana, the largest producer and developer of natural gas in North America, is investing $3 million in the project from its environmental innovation fund. Clean Current developed and built the prototype of a tidal turbine generator which harnesses the power of ocean currents to produce electricity. Testing will take place in about 15 metres of water, off Race Rocks, about 10 nautical miles southwest of Victoria. The tidal turbine generator, which functions like an underwater windmill, will be anchored to the seabed, and cables will carry away the electricity it generates.When the tide flows, the blades turn, explained Glen Darou, president of Clean Current. The blades have a permanent magnet attached to them. When the magnet passes by coils, the coils create electricity. The turbine works when currents are flowing in either direction. According to Darou, the project will have minimal impact on the environment. “We will have to disturb the bottom of the ocean with the turbine and cables but it’s a fast-growing marine environment and will recover quickly,” he said. “Anything that can swim in the tidal currents will not swim into the turbine, it will swim around it. But something that floats through like a jellyfish could actually go into it. That’s the size of the risk.” The prototype has been tested in fresh water, but Clean Current has to make sure its turbine generator works in saltwater. “Now we have to prove its operability and maintenance,” said Darou. Clean Current will know in about 18 months how the model and its one moving part — the rotor — stands up to corrosion in a harsh marine environment. The turbine will be monitored by underwater cameras. The prototype being tested is 3.5-metres in diameter and can produce enough electricity for 10 houses. Full scale models will be 14 metres in diameter and produce enough electricity for 250 houses. Darou envisions the day when there will be big underwater tidal turbine generator farms with up to 800 turbines that will produce electricity around the world. “The end of the dream will be our technology licensed around the world and applied in tidal environments all over the world. It’s seeing the technology used and replacing fossil fuels,” he said. The project will run at Race Rocks for five years. After that, Clean Current will sell the prototype to either B.C. Parks or Pearson College for $1. Clean Current still needs to come up with $1 million to pay for the project, Darou said. He expected the money will come from private investors and the federal government. The project will help the company and the province evaluate the future of this technology, said B.C. Energy and Mines Minister Richard Neufeld. Alternative energy will change how we consume fossil fuels over time, said Neufeld. “This is brand new, so let’s give it time to see how it works. Let’s give it time to see (how) technology can change it to make it more efficient.,” said Neufeld.

Project tests Race Rocks’ Tidal Power

Goldstream News Gazette  Mar 02 2005, By Rick Stiebel

  The tides of change are turning in Metchosin.  Lester B. Pearson College of the Pacific, Encana Corporation and Clean  Current Power Systems announced an innovative partnership Friday to  build a free-stream tidal power generator, the first of its kind in  Canada, at the Race Rocks Ecological Reserve.  The project, made possible by a $3 million investment from Encana’s  Environmental Innovation Fund, involves replacing two diesel-powered  generators at Race Rocks that supply power for Pearson’s marine  education centre with a tidal turbine generator, built by Clean  Current Power Systems.  The remaining funding for the $4 million project is expected to come  from private investors and the federal government.  The generator is scheduled to begin producing power by 2006.  The turbine generator has only one moving part, the rotor assembly  that contains permanent magnets. The turbine, anchored to the ocean  floor in about 15 metres of water, operates like an underwater  windmill with cables that carry away the energy it produces.  “This Canadian technology is simple, efficient and environmentally  friendly,” Clean Current president Glen Darou said at the Feb. 25  announcement at Pearson College.

 A prototype, which has been tested in fresh water, will be scrutinized  closely over the next 18 months to see how it holds up to corrosion  resulting from a marine, saltwater environment.  “This is a terrific project for Pearson College, in that it supports  our goal of making the ecological reserve a showcase for alternative,  low impact technologies such as tidal power,” said Pearson College  director Stuart Walker.  Pearson College staff and students played a major role in having the  site at Race Rocks, about three nautical miles from the Metchosin  school. Race Rocks was declared an ecological reserve in 1980.  The college is dedicated to protecting the marine ecosystems within  the reserve, while increasing awareness about marine systems,  ecological reserves and environmental issues, Walker said.

 Encana Corporation CEO president Gwyn Morgan said his company is  “pleased to be a partner in a first-class, alternative energy  project.”  “Our investment in this B.C. based unconventional environmental and  power technology reflects our desire to tangibly encourage innovative  energy solutions.”  Encana is one of North America’s largest independent oil and natural  gas companies, with an enterprise value of about $34 billion US.

 B.C. Minister of Energy and Mines Richard Neufeld praised the three  parties involved in the partnership.

 “The project certainly looks environmentally sound,” said Don McLaren,  area supervisor for B.C. Parks. “It will not only remove the diesel  generators on Race Rocks, but greatly reduce the noise factor.”  McLaren said the project will put Pearson College and B.C. Parks in “a  greener position, and help us and Pearson a lot.”

ENCANA PARTNERS TO ENABLE PEARSON COLLEGE – ENCANA – CLEAN CURRENT TIDAL POWER DEMONSTRATION PROJECT AT RACE ROCKS, BC Victoria
– Thanks to an innovative partnership between Lester B. Pearson College of the Pacific,EnCana Corporation and Clean Current Power Systems Incorporated, Canada’s first free-stream tidal power project will be built at the Race Rocks Ecological Reserve, offshore of Vancouver Island in British Columbia. The project will enable the world famous marine park to tap into surrounding ocean currents and convert tidal energy to electric power for its needs beginning in early 2006. Making the announcement were:
Gwyn Morgan, President and CEO of EnCana,
Glen Darou, President and CEO of Clean Current,
Richard Neufeld, British Columbia Minister of Energy and Mines,
and Stuart Walker, Director of Pearson College.1gwynOfficially known as the “Pearson College – EnCana – Clean Current Tidal Power Demonstration Project at Race Rocks,” the project is enabled by a $3-million investment from the EnCana Environmental Innovation Fund.“EnCana is pleased to be a partner in this first-class, alternative energy project,” said Morgan. “Our investment in this B.C.-based unconventional environmental and power technology reflects our desire to tangibly encourage innovative energy solutions.” EnCana’s Environmental Innovation Fund was established to advance new technologies and solutions that improve environmental performance associated with consuming and producing energy. Commercial proceeds from financed projects will be re-invested into the fund to ensure their sustainability.1minister“The commitment by Premier Campbell in promoting alternative energy sources has helped British Columbia become a world leader in sustainable environmental management,” said Neufeld. “The province commends projects like this one, as they show our commitment to developing clean energy solutions that will benefit all British Columbians.” The multi-year demonstration project will involve the installation, operation and monitoring of a 65kW free-stream tidal turbine generator in the water near Race Rocks, a provincial ecological reserve located 10 nautical miles southwest of Victoria.1glencamClean Current is a private British Columbia-based company that designs and licenses technology that efficiently converts the energy of tidal currents into electricity. Clean Current’s proprietary technology consists of a horizontal-axis ducted turbine with a direct-drive variable speed permanent magnet generator. The turbine generator is equally efficient in both directions as the tidal currents reverse twice each day.“This Canadian technology is simple, efficient and environmentally friendly,” said Darou. “We believe it is highly exportable technology, with strong potential to succeed in international settings. Our company is delighted to have the support of EnCana, Pearson College, and technical partners AMEC, Powertech Labs Inc. and Triton Consultants Ltd.”Pears1stuarton College, one of ten United World Colleges worldwide, is the custodian of the Race Rocks Ecological Reserve, located three nautical miles from campus. Diesel-powered generators currently provide electricity requirements at the reserve. Students and staff will work elements of the tidal power demonstration project into their studies.“This is a terrific project for Pearson College, in that it supports our goal of making the ecological reserve a showcase for alternative, low-impact technologies such as tidal power,” said Walker. “We would like to thank Clean Current for their commitment to developing the technology and EnCana for the financial support that is making this demonstration project possible.”1studentSecond Year Pearson College student Alyssa Holland (year 30) concluded the presentation , by thanking the speakers. As a student involved in Environmental Systems and the diving program, she shared the enthusiasm she has for the resources of the area and emphasized the great importance she and other students attach to the effort of those involved in this project in the ongoing goal of producing energy sustainably.Below is the complete version of her speach:

text of speech by Alyssa Holland (year 30)

As I am both an Environmental Systems student and a member of the diving activity, Race Rocks has played a central role in the education Pearson has given me. Race Rocks is truly the ultimate living classroom, teaching all those who interact with it about the beauty and wonder of the natural environment, and about the importance of responsible environmental stewardship. It is a very special place that gives so much to the college and its students, and it is very gratifying to think how much the ecosystem will benefit from the Clean Current project.

For Pearson students, Race Rocks is much more than a group of islands. On one level or another, we all interact with it and benefit from it, and consider it part of our home. Whether through poking around in the inter-tidal zone for class, or working with a researcher from the University of Victoria 10 metres underwater, or staying on the island for a weekend to give its 2 full-time residents a break, we have built a connection with this magical place. As such, ensuring its health and protection are very important to me, and to the student body as a whole.

Pearson is by its very nature an innovative place – even the concept of a United World College is radical and still experimental. I can think of no better or more appropriate environment for such an exciting new technology as this to be implemented, as it truly embodies the spirit of innovation and idealism that makes Pearson College unique. This new turbine will stand as much more than a symbol of scientific progress; it will also be a concrete demonstration that even an ideal as difficult to live by as environmentalism can be successfully put into practice when we are innovative. That will be a lesson to guide both students and visitors for years to come.

BACKGROUNDER: (Link to PDF version)Race Rocks is a unique ecosystem located at the eastern entrance to the Strait of Juan de Fuca, three nautical miles from Pearson College and ten nautical miles southwest of Victoria, BC. The rocky outcroppings that form the Race Rocks group of islands are the visible summit of an underwater mountain and are washed daily by tidal currents that can run at up to seven knots. These swift waters are the lifeblood of breathtakingly diverse plant and animal life – recognized internationally as a treasured ecosystem. To First Nations people, Race Rocks was a banquet table in the swift flowing waters known to them as XwaYen. To early mariners it was a formidable hazard to be avoided. To fishers it was a haven for finding rockfish and halibut. To scuba divers it is an underwater paradise with thriving colonies of marine organisms. To generations of future researchers, college students and school children, it will be an awe-inspiring outdoor and virtual classroom.

Lester B. Pearson College of the Pacific
Lester B. Pearson College of the Pacific (Pearson College), an international school named in honour of the late Prime Minister and Nobel Prize Laureate Lester B. Pearson, provides full scholarships to all its students. The College was established in 1974 and promotes international understanding and co-operation among young people and is one of 10 United World Colleges located around the globe. The 200 students attending Pearson College each year represent every Canadian province and territory, and there are representatives from over 85 other countries. Along with the International Baccalaureate academic program, students participate in a full activities program that includes: diving, kayaking, sailing and artistic endeavours such as choir, photography and visual arts. Each student also commits to volunteer service both at the College and in nearby communities. Pearson College staff and students have acted as long-time volunteer wardens at Race Rocks and were influential in having the area protected as an Ecological Reserve in 1980. As the environmental steward of Race Rocks, the College is dedicated to protecting the marine ecosystems within the reserve and to increasing the awareness of students, visitors and the public about marine systems, ecological reserves and environmental issues. By transforming a decommissioned light station into a dynamic educational and research centre, Pearson College has been able to share the rich cultural and environmental history of Race Rocks with Canadians and the world. Race Rocks serves as an award-winning showcase of sustainable and innovative educational initiatives and emerging technologies.

Clean Current Power Systems Incorporated
Clean Current Power Systems Incorporated is a private British Columbia-based company that will generate electricity from ocean tidal currents. Clean Current designs and licenses technology which converts the kinetic energy of tidal currents into electricity with unprecedented efficiency. This electricity is renewable, predictable and creates no greenhouse gases. The tidal turbine generator units are deployed completely underwater and cause no visual impact on pristine marine environments.

Efficiency and operability in salt water are the key ingredients of a successful tidal technology. Clean Current’s tidal turbine generator is a bi-directional ducted horizontal axis turbine with a direct drive variable speed permanent magnet generator. This proprietary design delivers better than 50 per cent water-to-wire efficiency, a significant improvement over competing free stream tidal energy technologies. Operability is enhanced by a simple design that has one moving part – the rotor assembly that contains the permanent magnets. There is no drive shaft and no gearbox.

The turbine generator has a design life of 10 years (major overhaul every 10 years) and a service life of 25-30 years. During that time it will generate electricity with zero emissions, a minimal footprint on the bottom of the ocean and negligible impact on marine life.
The Pearson College – EnCana – Clean Current Tidal Power Demonstration Project at Race Rocks is an important step in the Company’s technology development plan aimed at early commercialization.

To ensure success Clean Current has enlisted the assistance of technical partners AMEC Americas Limited and AMEC Dynamic Structures Limited (both subsidiaries of AMEC PLC),Powertech, (a subsidiary of BC Hydro) and Triton Consultants Ltd.

This proposal creates renewable energy to displace fossil fuels. The proposal conforms to Page 16 of the Race Rocks management plan for Facility Management

“Objectives:

•To showcase alternative, low impact technologies”

No specimens will be collected.

Existing buildings and conduits will be used wherever possible. One large hole will be drilled through bedrock to create a conduit for electrical cables (and system monitoring instrumentation) under water to about 3 feet above the high water mark. The purpose is to avoid shoreline turbulence and associated cable damage. Drilling one hole to place a post upon which the turbine generator will be mounted will disturb the bedrock in the middle of the passage.

Scheduling will be used to avoid disturbing birds during nesting season. Consultations with marine biologists will be used to assess impact before deployment of the unit. Underwater cameras will be used to monitor the impact of the turbine generator on fish and ocean mammals.

This will be the first free stream tidal turbine generator installed offshore in Canada and it will attract attention from commercial media. It is expected that Pearson College will publish studies of the ecological impact of this form of renewable energy.

Pearson College Input:

In keeping with our long term commitment to B.C. Parks the Marine Protected Area Initiative of DFO and the First nations to provide a level of stewardship for Xwayen, we would like to highly recommend this project.

The bottom line in our stewardship commitment is to keep the area ecologically sustainable and to ensure long term ecological integrity.

This proposal fills a serious need, the provision of low or no- impact technology for the generation of electricity to ensure our ability to operate in the reserve. We presently power the station and heat the residences with diesel fuel. The potential negative impact of this need on the ecology of the area could be enumerated as follows:

The fuel is supplied to the island on a bi-monthly basis by staff of the college using the boat “ Second Nature” Although we operate under the strictest standards for this transfer, the possibility always exists that a technical problem with the boat, failure

of transfer pumps and hoses, or human error could lead to a serious ecological impact if fuel oil escaped the transfer system.

The loud noise caused by the diesel generators is an irritant and has possibly discouraged some marine mammals from hauling out in the area. Harbour seals haul out for birthing in higher numbers a distance away from this otherwise ideal location.

The aesthetics on the otherwise pristine environment of the island of the generator noise is a legitimate concern.

Five species of Marine birds nest on the island. The constant noise from the generators could be impacting negatively on behaviour: predator response capability, foraging and mating/nesting behaviour.

Fuel storage on the island is by double-hulled 1000-gallon tanks which currently meet the required environmental standards but which do have a life span and therefore will eventually need replacement. Also since there are probably no other parallel examples of such diesel oil storage in ecologically sensitive areas, it is doubtful whether existing standards are adequate.

The fuel storage tanks on the island are vulnerable in the event of earthquakes.

The severe weather that the area experiences on many days of the year and the high tidal currents ( up to 7 Knots) mean that containment of spilled oil by booms would probably be impossible, resulting in severe species loss in the intertidal zones of the islands.

 

The marine reserve at Race Rocks, power the research and education facility at Race Rocks with a technology that allows for minimum disruption to the ecological integrity and the long term sustainability we see this proposal as a welcome innovation .

Interview with Taco Niet on Alternative Energy for Race Rocks

In 2002, Taco Niet finished his Masters degree in the Engineering Department’s Institute for Integrated Energy Systems at the University of Victoria (IESVic). In this clip, Garry interviews Taco about his research on renewable energy systems for Race Rocks. Great resources are available out there such as wind, solar and tidal energy. In order to conserve the natural aspect of the island, while reducing the use of Diesel fuel, many challenges arise. Taco considers the project can be integrated nicely with the racerocks.com project in order to be widely accessible on the internet and serve as a model for monitoring and comparing energy generation.
