EDP Renewables 2013 Annual Report

Engineering & Construction





A main goal of EDPR’s engineering and construction team is to build highly efficient wind farms, while closely monitoring the investment costs, and to design wind farms that will require minimal infrastructure maintenance costs during the useful life of the asset. This is done with strict adherence to local and internal construction standards, considering on-site conditions and minimizing the impact on local communities and the environment.

During the engineering phase EDPR’s teams perform deep geological researches with the aim of avoiding uncertainties during construction as well as designing optimal foundations, roads and platforms. The proper design of roads and other structures minimizes the use of earthworks, which ultimately reduces the construction costs of each project.

The electrical infrastructure requires equal time and effort. In this stage the choice of cables takes into consideration the best economics as well as the technical characteristics of the wind turbines to ultimately design the best electrical grid crossing.

The infrastructure investments developed have an ultimate positive benefit for the surrounding communities. The reinforcement of the existing electricity networks and the rehabilitation of existing roads, or the construction of new roads, is a valuable asset for the surrounding communities who may be able to use the developed infrastructure to access remote locations. Moreover, an upgraded electricity distribution system can increase the quality of the electricity supply by increasing stability and reducing outages.

The presence of EDPR in the area encourages economic development of the region, which can see an influx of temporary construction workers that brings local spending and increased sales tax revenue. Closely collaborating with stakeholders is important to ensure they maximize the value generated.

In the construction phase, EDPR stands out through its contract strategy and procurement process, among others. EDPR has perfected its contract strategy to provide the best balance between price and risk. This is done through several turnkey contracts for the wind turbines, construction works and electrical infrastructure that guarantee internal leadership in the construction management, whilst reducing the prices and controlling the schedule and possible deviations.

With regards to the procurement process, EDPR has implemented a process that guarantees technical considerations and competitive pricing. This includes a bidding process for several contractors with several stages of negotiations.

Commercial and technical assessments are carried out in parallel to get the best commercial offer (economics, guarantees, low risk, financing) to assure the whole scope is included and quality and technical specifications are fulfilled.

Environmental requirements and best practices are also included in the bidding documentation or in specific environmental management plans. The construction of our projects brings many external partners and we believe it is essential to involve the entire value chain in order to guarantee that they are aligned with our environmental strategy. EDPR performs monitoring plans to ensure that the environmental requirements are met and in the unlikely event that an unexpected environmental impact is identified we are able to quickly implement the corrective measure.


Guaranteeing a healthy and safe work environment for our employees and contractors is fundamental in all aspects of the business. EDPR’s Health and Safety policy, available on our website, reflects the company’s commitment to the prevention of occupational risks associated with our  activities.

To support our strategy on health and safety, we have implemented proper management systems. These systems are adapted to each country, with specific standards and procedures based on the regulation and best practices.

The Management System is being certified OHSAS 18001:2007. At the end of 2013, the certification covered 3,387 MW, representing 42% of EDPR’s installed capacity. The certification was additionally extended to Belgium and Romania.

During 2013, EDPR registered a substantial improvement in its health & safety ratios. The number of accidents registered for employees and  contractor personnel reduced by 50%, an improvement towards our zero accidents goal stated in our Health & Safety policy.
