Renewables

In the Renewables division, we provide highly demanding, complex and large-scale consultancy and engineering services. With perfect knowledge of technological advances in the energy market, we develop innovative solutions that are functional, reliable and, above all, sustainable, both from the construction standpoint and operating costs and from an environmental viewpoint, liaising our projects with the rest of the company’s teams in order to deliver projects with an above-average level of coordination and knowledge.

With an experienced team, we work in the renewable energy production sector, namely in designing photovoltaic solar power stations of various types and technologies, both for self-consumption and utility scale, being familiar with solar power station projects on the ground using fixed technology or with a tracker, on a roof and/or cartop, and on the water using floating technology. We have also developed wind farm projects using the latest technology, both for new projects from scratch and for retrofitting and overfitting existing wind farms. Finally, as both technologies are complementary in terms of their energy production cycle, we also develop energy storage projects with batteries (BESS), supporting our clients in outlining the project strategy and following it through to implementation.

In line with our clients and Quadrante’s internationalisation strategy, we develop multidisciplinary projects in Portugal, Europe, Africa and Latin America.

Based on Quadrante’s strategy of innovation and of being at the forefront, we develop our projects using software such as PV Case, Autocad Civil 3d and PV Syst. To support engineering, we also use a set of IT tools that are governed by international standards, allowing our work to be recognised worldwide.
