100% renewable energy? Only with the right cable infrastructure!
Why our grid is currently overwhelmed
Grid bottlenecks
**Cause:** Old power lines designed for central plants, not decentralized energy. **Solution:** New high- & medium-voltage cables.
Curtailment of solar & wind power
**Cause:** Grid cannot absorb enough electricity. **Solution:** Smart grids & storage solutions.
Long transmission distances
**Cause:** Generation is often far from consumption. **Solution:** High-performance cables & local grids.
⚠️ A grid from the past cannot transport the energy of the future!
Anyone investing only in renewable energy systems today while ignoring cable infrastructure will be left with expensive, unused electricity tomorrow.
# Which cables do we need for the energy transition?
Not all cables are created equal – and not every cable is suited for the challenges of the energy transition. Voltage level, capacity, and efficiency are key factors.
## The three pillars of energy transition cabling:
⚡ [High-voltage cables](https://en.wikipedia.org/wiki/High-voltagecable) → Long-distance power transmission<br />⚡ [**Medium-voltage cables**](https://en.wikipedia.org/wiki/Powercable) → Grid connections for solar & wind farms<br />⚡ [Low-voltage cables](https://en.wikipedia.org/wiki/Low_voltage) → Connecting households & storage systems
🔍 What makes a good renewable energy cable?<br />✔ High load capacity for fluctuating power inputs<br />✔ Weather- and temperature-resistant insulation<br />✔ Sustainable materials for a low-carbon power grid
💡 The better the cable, the less electricity is lost along the way – and the greener the energy becomes!
# Solar and wind farms aren’t enough
Without the right cables, electricity stays where it’s generated. But what kind of grid expansion really makes sense?

Underground cables vs. overhead lines – which is the better choice?
Underground Cable
Overhead Line
Grid stability
Very high
Moderate
Environmental impact
Unobtrusive, no disruption to landscapes
Visible, problematic for birds
Maintenance & lifespan
Minimal maintenance, long lifespan
Weather-sensitive, shorter lifespan
Costs
Higher installation costs, but more efficient operation
Cheaper to build, but higher long-term costs

The future belongs to grids that don’t just transport electricity but actively manage it. This means we don’t just need more cables, but the right cables—equipped with intelligent technology.
# Conclusion: The energy transition starts underground
Discussions about renewable energy often focus on expanding wind and solar farms. Yet, the crucial infrastructure needed to make this energy reliably usable is rarely addressed.
The reality is clear: A modern power grid is the key to the energy transition. If electricity cannot be efficiently transported or stored, grid bottlenecks and curtailments occur—the exact opposite of what the energy transition aims to achieve.
## Three key takeaways:
- Renewable energy needs powerful grids. Without a solid cable infrastructure, much of the electricity generated remains unused because the grid cannot absorb it.
- Investing in cables is just as important as investing in generation. While new wind turbines and solar plants are visible, the necessary grid expansion remains largely invisible—and is therefore underestimated.
- Without smart grid technology, fluctuations cannot be managed. Modern cables with integrated control technology are essential for delivering energy exactly where it’s needed.
