The plant was facing structural deficiencies and several initiatives had been taken by WavEC in collaboration with the Azores Regional Government in order to recover the structure and promote the plant within the region.
Considering that the plant had already fulfilled its objectives as a pilot demonstration project, and in view of the wear and tear on the submerged part of the structure, in February 2016 WavEC’s Board of Directors communicated its decision to close the plant, requesting the requirements to ensure safe and environmental conditions.
In January 2017, due to the interest shown by the Regional Government in a viability analysis of the recovery of the plant, WavEC suspended its decision to close. However, as it was not possible to conclude its feasibility, the project to dismantle the plant went ahead, being prepared by EDA and EDP.
After the partial collapse of the plant on April 17 2018, all the necessary measures were taken to contain potential risks, the plant was disconnected from the network and security measures were taken.
The Pico Plant has made a very valuable contribution to the promotion of wave energy research, development and innovation, both at a national and international level. During its lifetime it attracted funding from more than 11 national and European projects, together worth over 35 million euros of this, only about 1.5 million euros were of national origin. These 11 projects directly contributed roughly 2 million euros to the operation and maintenance expenses of the plant, and to the research activities carried out by the local team. The Pico Plant was part of two European networks of test infrastructure for wave energy technologies (MARINET AND MARINET2), promoting the access of international teams to the plant. The plant originated more than 100 international scientific articles and was associated with more than 8 doctoral theses and numerous master's theses and scientific internships.
