The Traditional Power Generation System at Race Rocks

Being an isolated Light Station, Race Rocks relied fully on power generated on site up to October of 2006. Electricity was supplied after the start of the light tower in 1860 by a series of diesel run electrical generators.So far we have no information on the kind of generators used in these early years. This page provides a profile of the diesel electrical generating system which now forms part of a back-up for our integrated energy system.

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.

Turbulent tides tumbling by Race Rocks will test how well a new tidal turbine generator stands up to the harsh west coast environment. The project is expected to produce more than enough electricity to replace two diesel generators and provide power to the suburban Metchosin 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.

CollegeReseachers Testing Tidal Power B.C. news roundup: Feb. 26 Broadcast News Saturday, February 26, 2005Pearson College near Victoria is testing the waters of tidal power with a new turbine generator to run the Race Rocks ecological preserve. It’s a $4 million experiment to see how well the new turbine stands up to the harsh west-coast environment. If it works, the unit will replace two diesel generators by March 2006. The project is being sponsored Calgary-based energy producer EnCana Corporation and Clean Current Power Systems of Vancouver.

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.”

A UVic study explores renewable energy options at Canada’s newest Marine Protected Area

The essence of Race Rocks is its tides. Tides that feed biodiversity. Tides that have brought ships to their knees upon its rocky shores. And tides that may bring it to the forefront of renewable energy technology.
For his recently completed master’s thesis, UVic mechanical engineering graduate student Taco Niet has created a model that shows tidal power to be the most realistic source of renewable energy for Race Rocks.
A collection of nine tiny islets with a big reputation, Race Rocks is situated 17 km southwest of Victoria at the eastern end of the Strait of Juan de Fuca. Its reefs and strong tidal currents — up to seven knots — support an exceptional diversity of marine life, including invertebrates, fish, seabirds and marine mammals. In 2000 it became Canada’s first Marine Protected Area created under the federal Oceans Act.
Race Rocks hosts a lighthouse, occasional researchers and educators, and two full-time guardians employed by Lester B. Pearson College. The college has also installed a local area network that allows Internet video coverage around the clock, accessible at www.racerocks.com.
While the light tower and foghorn are powered by solar panels, a diesel generator supplies the guardians with the energy required to live full-time at Race Rocks, including energy-costly water desalination. Several times a year, diesel fuel is transported to the island by boat and pumped into storage tanks, an enterprise with plenty of potential environmental hazard.
Garry Fletcher, educational director at Pearson College, initiated the renewable energy project through contact with UVic’s institute for integrated energy systems (IESVic). Institute director Dr. Ged McLean, Niet, and two other students soon began preliminary energy modeling.
Niet later took on the project as a master’s thesis. He modelled the hourly energy flows for an entire year, using information collected by electronic monitors that recorded energy use, wind speed, sun exposure and tidal flow. McLean stresses the importance of Niet’s model.
“It’s the only one we know of that tracks energy production and demand on an hourly basis. Most models use a larger time scale, glossing over the amount of time when energy production is zero.” McLean adds, “Taco also made his system entirely self-contained — there are no traditional back-up systems in the model, making it especially relevant to small, isolated communities.”
In the end, gleaming solar panels and spinning wind turbines were not the best choice; it was the eggbeater-like tidal turbines that came out tops. Niet says it’s not surprising that tidal power emerged ahead of solar and wind.
“Tides arrive every six hours, every day, year-round,” he points out. “They’re reliable.” Tidal ebb and flow result in the most favourable balance between energy production and demand, requiring less energy storage than either of the alternatives.
“We see the Race Rocks model as an alternative energy parable,” Niet muses. “It provides a realistic picture of what we can — and can’t — do with renewable energy.” Seasonal variation in many renewable energy sources requires large investments in energy storage. “Blanketing every inch of an area with solar panels is not exactly environmentally friendly,” Niet explains, “not to mention the environmental and economic costs of making the panels.”
While Niet’s model currently exists only on paper, the Race Rocks energy parable could soon become a reality. Niet is searching for an industrial partner to take the next step. “We need to conduct an environmental assessment,” Niet says, “and if the results are favourable, we’ll require funding to implement the turbines”.
Meanwhile, Niet, McLean, and McLean’s new students forge ahead. Their next project? “North America is the next, logical self-contained unit to model,” enthuse Niet and McLean. “Our goal is to understand what a realistic future looks like,” McLean explains, “and how sustainable energy technology fits in that world.”
Funding for Niet’s work was provided by McLean’s Natural Sciences and Engineering Research Council operating grant.

Abstract
Race Rocks is a small archipelago located just Southwest of Victoria, British Columbia in the Juan de Fuca Strait. An important Beacon for Coastal Navigation in this busy area is located on Race Rocks, which is also home to a stunning variety of marine mammals and birds. The Race Rocks site has become Canada’s first Marine Protected environment and is now carefully managed by a group of interested partieScreen Shot 2014-02-24 at 7.48.10 PMs including Pearson College and The Canadian Coastguard. The environmental integrity of the site is often jeopardised to bring diesel fuel to the site and the noise pollution on the site due to the diesel generators is significant. IESVic has stepped forward to evaluate the potential of renewable energy sources on-site to power a sustainable energy system. A preliminary study was performed as an innovative graduate course at the University of Victoria that exposed students to sustainable energy system design. Our conclusion is that with Tidal currents of up to 3.7 m/s, average winds of 21.6 km/h and large amounts of solar insolation, there are ample renewable resources available on the site to develop a sustainable integrated energy system capable of providing reliable power for the site. Race Rocks is therefore ideally
suited to become a showcase for renewable energy generation. This paper outlines the results of the feasibility study, discusses the opportunities available at Race Rocks and examines the progress to date. Requirements for the implementation of a sustainable energy system on the site are discussed.
