Portugal’s Alqueva 50 MW Floating PV tender open for proposals


EDIA started the request for qualification stage for a solar tender that will support 4 floating photovoltaic plants, totalling 52MWp, in reservoirs integrated in the Alqueva irrigation system, creating Europe’s largest floating photovoltaic project, occupying over 42hectares and using over 100,000 solar panels.

The tender seeks companies or consortia for engineering, procurement and construction (EPC) as well as operation and maintenance (O&M) for a 3 year period, at a maximum price of 45M€.

This first phase of the tender will be used to select companies or consortia with proven experience in floating photovoltaic technologies, in terms of design, construction and operation of large plants, in addition to other technical requirements and financial capacity. Proposals must be submitted on the public procurement platform ( until 11th january 2024. All documents that constitute the proposal must be written in Portuguese.
Subsequently, qualified entities will be invited to present proposals, with the evaluation criteria considering the price, technical performance and extended warranties of the proposed equipment.

EDIA – Empresa de Desenvolvimento e Infra-estruturas do Alqueva, S.A., is a public company owned exclusively by the portuguese state, and is fully staffed to design, operate, manage, maintain and promote the Alqueva Multipurpose Project.

Located in Alentejo, in the south of Portugal, Alqueva is a multiple purposes project, where the Alqueva dam, built on the international Guadiana river, is the water source for a system made up of a total of 72 reservoirs and with a water distribution network longer than 2200 km.
Centered on the Alqueva reservoir, Europe’s largest man-made strategic water reserve, with a total capacity of 4,15 billion cubic meters, the Alqueva Multipurpose Project has a size, scope and modernity of infrastructure that currently allows it to irrigate an area of 150,000 hectares, produce hydroelectric energy with pump-storage, enabling total complementarity with photovoltaic plants, public and industrial supply, preservation of the environment and heritage, territorial planning and the development of tourist activities.

EDIA promotes Case Study within the scope of the MERLIN Project


MERLIN is a European Project that promotes nature-based solutions (NbS) as a main method to tackle current social issues such as climate change, biodiversity loss and other challenges addressed by the European Green Deal.

With a total of 18 case studies, in 15 European countries, EDIA is responsible for the Case Study 18 (CS 18), relating to the Ervidel Floodpalin, which comprises the implementation of ecological restoration interventions of a “Xacafre” segment stream and respective floodplain, and also with the plan to install flower meadow areas and shelters for the pollinators reproduction as a measure to promote biodiversity.

The Case Study 18, to be developed in a stream of “Ervidel” Irrigation Perimeter, integrated in the Alqueva Multi-Purpose Development, was identified as a Twinning Case Study of “Sorraia” Case Study 13. The CS18 having been approved by the European Commission, following an application submitted by the Institute Agriculture School (ISA), with EDIA as the partner of the implementation project.

The restoration interventions fall into three fundamental tasks:
   1. Ecological Restoration of the riparian gallery of a stream segment (also known as Vale de Água/Pero Bonito stream), through the implementation of measures with different types of intervention, namely cleaning (pruning, cleaning, unblocking and desilting); planting indigenous riparian tree and shrub species; implementation of techniques using natural engineering and maintenance actions;
   2. Sowing a flowering meadow, with a mixture of native herbaceous species for pollen production, in an area of approximately 1 hectare;
   3. Installation of pollinators hotels – with the aim to creating shelters for pollinator reproduction.

The 18 case studies cover a sectors variety, including Agriculture; Water Supply; Hydroelectric; Navigation; and Peat Extraction, and are distributed across 15 European countries, and there are countries with more than 1 case study, such as Portugal, which presents 3 Case Studies (CS) – CS 12 Lima Catchment; CS13 Sorraia Floodplain and the EDIA Case Study – CS18 Ervidel Floodplain.

The Project “MERLIN–Mainstreaming Ecological Restoration of freshwater-related ecosystems in a Landscape context: Innovation, upscaling and transformation “ is co-financed by the H2020-IA (Innovation Action) program, coordinated by the Druuisberg-Essen University in Germany, with the “Instituto Superior de Agronomia”(ISA) as Scientific Partner.
