For a sustainable future, modern engineering constructions for the utilisation of renewable energy play an increasingly important role. The targets of the federal government up to the year 2020 for a reduction in greenhouse gases, can only be met through a technically feasible mixture of a variety of renewable energy sources.

We take on the planning, management and supervision of renewable energy construction projects, right up to their successful implementation. Close cooperation with our clients and the authorities is a natural component of our work, assured through our internal quality management systems.

We offer comprehensive expertise in the following areas

  • Project management
  • Supervision of renewable energy engineering constructions
  • Structural design
  • Technical equipment planning
  • Technical surveying services
  • On-site construction supervision

We create energy strategies that allow an energy management process to be run in advance. As part of the energy management process, consultations, surveys and recommendations about the modernisation/optimisation of the existing technology are provided. The goal is to save energy, as well as to reduce total expenditure.

The energy audits that are undertaken, serve to identify energy peaks and pinpoint possible savings through reliable status analyses. As a result, an energy strategy emerges with an audit report and a corresponding package of proposed measures.

We offer comprehensive expertise in the following areas

  • Energy management
  • Energy audits
  • Creation of energy strategies
  • Investigation of alternative options

The planning of cable routes for wind and solar parks, or for telecommunications, demands not only technical expertise, but is also bound up with a series of legal challenges.

We undertake the route planning from the generation to the feed-in point. In cooperation with the environmental authorities, we deal with the ecological inspection of the whole route, and prepare documentation for all necessary official decisions.

The search for a route involves looking at several options. We generate implementation planning for the best option and support the construction project to its realisation.

We offer comprehensive expertise in the following areas

  • Cable route planning for wind and solar parks, and for other supply and waste disposal routes
  • Route-finding with options
  • Authorisation applications concerning railways, waterways, motorways, federal, state and district road, etc.
  • Securing of easements for the entire route
  • Ecological inspection of the entire route, including environmental services
  • Implementation planning with surveying services
  • On-site construction supervision

We create overall locality strategies for wind farms, solar parks and biomass power plants. In order to find appropriate landscapes (and above all, environmentally compatible locations), igr has undertaken location searches both in Germany and abroad.

We investigate conflicting uses and consider them with regard to safety margins. We investigate ‘hard’ and ‘soft’ taboo zones. After an elimination process, the remaining restriction-free areas undergo further analysis. An evaluation of the suitable areas follows as a result.

On the basis of this comprehensive and neutral investigation, and the resulting suitable areas, towns, municipal authorities and administrative districts can make decisions as to which areas could be designated for use as wind farms, solar parks and biomass power plants.

We offer comprehensive expertise in the following areas

  • Overall locality strategies for wind energy, photovoltaic (free-standing and roof-sited) and biomass power plants
  • Investigation of hard and soft taboo zones
  • Evaluation of potential areas and investigation of suitable sites
  • Drawing up of plans by means of geographical information systems (GIS)
  • Designation of special areas for renewable energy through the updating of land use development plans
  • Preparation of environmental reports and expert reports on species protection law (including mapping)

We prepare feasibility studies of various types, for example analysis of development potential, cost-benefit analysis and economic viability analysis in connection with the development of renewable energy. The goal is to create a sustainable, CO2-reduced future. In the course of the analysis, technical, legal, economic and nature conservation background conditions are examined, along with possibilities and restrictions.

The considerations focus on wind farms, solar parks and biomass power plants in relation to the given requirements, specific to the state or region in question.

We offer comprehensive expertise in the following areas

  • Feasibility studies
  • Analyses of development potential
  • Clarification of the technical and legal background conditions
  • Cost-benefit analyses
  • Nature conservation background conditions and restrictions
  • Economic viability analyses
