The expansion of the German extra-high-voltage grid is a crucial component of the energy transition - and it is taking place in now take place. Planning, approvals and construction work are running in parallel throughout Germany. A significant number of the new lines are already in operation, while other sections are under construction or are about to be authorised. In total, several thousand kilometres of new line systems are being built to transport electricity from renewable energies safely, stably and with low losses in the future.
In this complex environment, the M&P Ingenieurgesellschaft- Member of the SIERA Alliance - the responsible steps of grid expansion with comprehensive, professionally qualified environmental assessment and water-related construction monitoring.
1. what has happened so far in grid expansion
A considerable part of the grid expansion has already been realised in recent years:
- Construction of several hundred kilometres of new extra-high-voltage lines
- Reinforcement of existing routes
- Planning and initial construction of high-capacity HVDC lines (direct current connections)
- First sections of major pipeline projects approved
- Several major projects are already under construction
The transmission system operators and the Federal Network Agency are driving this development forward in order to make Germany's energy infrastructure fit for the future.
2. current status and outlook for the coming years
Germany is in the middle of the implementation phase:
- Numerous authorisation procedures running in parallel
- Some of the pipelines have already been completed
- Further projects are under construction
- Many projects are about to be approved
Until Early/mid-2030s central north-south connections are to be completed - including:
- SuedLink
- SuedOstLink
- A-North
In addition, existing power lines are being modernised, new substations are being built and the digitalisation of the grids is being intensively driven forward. The aim is to Stable, flexible and safe power transport, even with strongly fluctuating wind and solar power.
3 Why is the extra-high-voltage grid being expanded?
Grid expansion is crucial to achieving the key goals of the energy transition:
Central drivers
| Reason | Significance for grid expansion |
| Energy transition | Renewable energy is often generated far from the centres of consumption - the grid must transport it reliably. |
| Security of supply | A strong grid prevents bottlenecks and power outages. |
| Shutdown of fossil and nuclear power plants | The loss of power plant capacities requires new transport routes from north to south. |
| Climate protection | Only an expanded grid enables the full utilisation of renewable energies. |
In short: Grid expansion is well advanced, but is far from complete. It is key to ensuring that Germany has a reliable, stable and climate-friendly supply of electricity in the future.
4. contribution by M&P Ingenieurgesellschaft Hamburg und Hannover - member of the SIERA Alliance
The extra-high-voltage grid expansion projects are supported by experienced experts. The M&P Ingenieurgesellschaft- Member of the SIERA Alliance - plays an important role in the planning and construction phase.
4.1 Environmental assessment on behalf of the Federal Network Agency
M&P Ingenieurgesellschaft ensures that all the necessary documentation is complete and technically sound right from the early stages of the project. This includes in particular
- Examination of environmental expertise
- Evaluation of species protection documents
- Control of professional and legal capacity
- Ensuring completeness and plausibility
The results of these tests are directly into the authorisation texts in. This ensures that major projects are prepared not only technically but also ecologically to a high standard.
4.2 Hydrological construction monitoring - environmental responsibility on the construction site
Even during the construction phase, the M&P Ingenieurgesellschaft- Member of the SIERA Alliance - actively involved in the project.
As Hydrological construction supervision takes them over:
- Monitoring of all water-related aspects on site
- Protection of soil and groundwater
- Checking whether construction measures fulfil the environmental objectives
- Specialist support for water management issues
- Early identification and minimisation of potential environmental impacts
This will ensure that the expansion of the extra-high-voltage grid not only fast and reliable, but also Environmentally friendly and sustainable is progressing.
5 Conclusion: Grid expansion can only succeed with technical and ecological quality
The expansion of the German extra-high voltage grid is one of the most important infrastructure projects of the energy transition. M&P Ingenieurgesellschaft Hamburg und Hannover - a member of the SIERA Alliance - is making a decisive contribution by:
- examines environmental expertise
- Technical support for authorisation procedures
- water-related construction supervision
- ensures ecological quality standards
This will create an electricity grid that meets the needs of a climate-friendly, secure and efficient energy future.
