As a part of environmental management services, an assessment of the possible impact (positive or negative) that a proposed project may havRenewable energy power plants being complex technical systems, they require regular maintenance to ensure an efficient and safe operation, as well as to maximize their lifetime. In case of wind turbines in particular, they contain wear & tear parts and require working fluids and lubricants (e.g. oil filters, gear oil, cooling liquids, brake discs, etc.) which have to be changed regularly. This kind of maintenance is carried out in regular intervals and according to a specific scope, both defined by the manufacturer’s maintenance manuals and common industry best practices. It typically comprises of:e on the environment, considering natural, social, and economic aspects is in the core of the structure and project development process of almost all RE projects. The purpose of the EIA is to ensure that decision-makers consider the ensuing environmental impacts to decide whether to proceed with the project.
