Marine Renewable Energy: Tidal Power


Nova Scotia is investing in tidal power and while the industry has been slow to develop here, there have been recent developments that show projects finally underway. This course offers you a great opportunity to get real insight into the tidal community and learn about what is happening, why decisions are being made and how developers plan to move forward. This is an exciting time for those interested in ocean technologies and renewable energy in Nova Scotia and if you’re looking to determine where you fit - this course is the place to start. The pace of technology development needs to be fast because the technical challenges are many and innovative solutions are required at every step.

This course will start with a look at the story of tidal in Nova Scotia so far. We will learn the fundamentals of electric power production and how In Stream Tidal Power devices operate, and explore the difficulties being faced in connecting the power to the grid. We will consider the marine environment of the Bay of Fundy and discuss socio-economic impacts. We'll discuss government policies, look at individual tidal projects currently underway in Nova Scotia and learn about the organisations in Canada focused on the support and promotion of tidal energy.

You will leave this course with an understanding of:

  • What is happening with tidal power in NS
  • How tidal power is progressing globally
  • The fundamental operation of the various technologies
  • Current issues facing the industry
  • What you will want to learn next


  • Inform participants about what is happening with tidal power in NS
  • Gain a basic understanding of the tidal power systems that are being developed and deployed in Canada
  • Learn the technical challenges ahead in this industry
  • Familiarize participants with environmental and socio-economic issues

Who should attend

Professionals in the engineering and environmental science fields, engineers, scientists, technicians and technologists, those who may impact policy or regulations around tidal power, ocean technology specialists, anyone who would like to get a basic understanding of Tidal Power.

Benefits to participants

Taking this course will give participants a fundamental understanding of the tidal power industry, a basic understanding of the science and engineering behind the devices, the technical and environmental challenges and the issues facing the deployment of devices. This will allow anyone interested in getting involved in the field to make an educated decision on where their talents will be best used. The course is being presented by a local tidal expert who is well connected in the industry and happy to share experiences with participants. Finally, guest speakers from government and industry will provide insight into aspects of the course.

Sue Molloy, PhD, MEng, BEng, BSc, based in Halifax, Nova Scotia, Canada, is a consulting engineer, researcher and adjunct professor in Ocean Engineering, specializing in Marine Renewable Energy, Eco-Ships and sustainable engineering. Recently, Sue guest edited the Journal of Ocean Technology Ocean Energy issue and appeared on Global morning TV in Halifax to discuss Tidal Power. Sue is regularly invited to speak to engineering organizations and institutions on Tidal Power around the country. She is the international convener for the International Electrotechnical Committee TC114 River Turbines ad-hoc committee and one of the 3 Canadian delegates on the Design subcommittee of IEC TC114 Marine Energy. Sue was hired by FORCE to develop their instrumentation R&D and is a co-chair of the Fundy Energy Research Network (FERN) Engineering Sub-Committee. She was the executive secretary for the Engineering Committee on Oceanic Resources (ECOR) and chair of the ECOR Specialist Panel on Marine Renewable Energy, which has recently been subsumed into the Society for Underwater Technology (SUT). Sue teaches sustainable engineering and turbomachines for the Dalhousie University, Faculty of Engineering and has taught sustainable design and renewable energy at OCAD University in Toronto. Sue is an adjunct professor in the Faculty of Engineering at Dalhousie and a research associate at ACER at Acadia University. Sue has worked on research and consulting projects related to educating communities about investing in tidal power, the development of tidal power test facilities, testing methods for tidal turbines, cabling of tidal turbines and the efficiency and environmental effects of power systems. Sue is currently working with and Black Rock Tidal Power on the development of a Tidal Power project in the Bay of Fundy at the FORCE.
