This paper presents the results of a pilot experiment with an existing tidal energy converter (TEC),
Evopod 1 kW floatable prototype, in a real test case scenario (Faro Channel, Ria Formosa, Portugal). A
baseline marine geophysical, hydrodynamic and ecological study based on the experience collected on
the test site is presented. The collected data was used to validate a hydro-morphodynamic model,
allowing the selection of the installation area based on both operational and environmental constraints.
Operational results related to the description of power generation capacity, energy capture area and
proportion of energy flux are presented and discussed, including the failures occurring during the
experimental setup. The data is now available to the scientific community and to TEC industry developers,
enhancing the operational knowledge of TEC technology concerning efficiency, environmental
effects, and interactions (i.e. device/environment). The results can be used by developers on the licensing
process, on overcoming the commercial deployment barriers, on offering extra assurance and confidence
to investors, who traditionally have seen environmental concerns as a barrier, and on providing the
foundations whereupon similar deployment areas can be considered around the world for marine tidal
energy extraction.

This paper investigates the effects of Tidal Energy Converter (TEC) array size at a tidal channel on flood/ebb discharges at multi-inlet coastal lagoon by applying numerical modelling. The paper presents a case study for the Faro-Olhão inlet in the Ria Formosa (Portugal), a potential site for tidal in-stream energy extraction. Arrays of up to 11 rows with 5 TECs each were studied to assess impacts on inlets discharges changes. For the particular cases assessed the results show that tidal energy extraction will have a greater impact on Ancão and Armona inlets discharges together with the Faro-Olhão inlet. Future work is directed to include impacts on sediment dynamics and optimise TEC array size as a function of multiple design variables subject to environmental constraints.
