IEC TC 114 – Marine Energy

Inaugural Meeting in Ottawa, CA on May 14-15, 2008

Fall 2007 – SMB approved the formation of a new Technical Committee (TC) 114 on Marine Energy: Wave, tidal and other water current converters

British Standards Institute (BSI), United Kingdom holds Secretariat

Scope of IEC TC 114

To prepare international standards for marine energy conversion systems. The primary focus will be on conversion of wave, tidal and other water current energy into electrical energy, although other conversion methods, systems and products are included. Tidal barrage and dam installations, as covered by TC 4, are excluded.

IEC TC 114 Standards

Standards produced by TC 114 will address: System definition Performance measurement of wave, tidal and water current energy

converters Resource assessment requirements Design and safety requirements Power quality Manufacturing and factory testing Evaluation and mitigation of environmental impacts

Costs of Energy

Costs of energy generated by wave & tidal energy converters deployed in initial farms

(Source: Carbon Trust, 2006)

Cost estimates for ocean technologies have high uncertainty, given that few devices have actually been manufactured at full-scale and tested under normal operating conditions.

1 GBP = 1.8 CAD

Future Costs of Energy

Optimistic estimate

Initial cost $ 39c/kWh

Learning curve 15%

Pessimistic estimate

Initial cost $45c/kWh

Learning curve 10%

Cost of energy as a function of installed power (Source: Carbon Trust, 2006):
