Smart Grids Start Local—But Their Impact Should Be Portfolio-Wide

While most of the energy transition headlines focus on generation—wind farms, solar panels, hydrogen—some of the most critical innovations are happening quietly, inside our neighborhoods, at the grid level. The EKZ OrtsNetz pilot in Winkel is a perfect example of how small-scale, smart infrastructure decisions can reshape how we think about energy—not just for utilities, but for real estate owners too.

Over the course of three years, EKZ tested what a decentralized, intelligent electricity grid might look like. Their aim was to reduce peak loads—not by building more grid infrastructure, but by using data, digital twins, dynamic tariffs, and smart steering systems. The result: significant reductions in solar peak stress, better load management, and targeted infrastructure investments rather than blanket overhauls. You can read more in their official project interview here.

But here’s the part that should really speak to real estate portfolio owners: this kind of innovation isn’t just for utilities. It’s a blueprint.

When applied at scale across a portfolio of buildings—whether residential, commercial, or mixed-use—systems like those tested in Winkel can become powerful levers for operational efficiency, tenant value, and financial return. Imagine dozens, even hundreds, of buildings operating on aligned technical setups, responding to grid signals with smart heat pumps, EV chargers, or boilers. Suddenly, your buildings are not just consumers of energy, but assets in the grid—and that’s a position of strength.

The benefits compound at scale:

• Standardized infrastructure means lower installation and maintenance costs.
• Bulk procurement of smart systems increases bargaining power.
• Contracting models become viable—where part of the energy optimization investment can be passed on to tenants as part of a service upgrade.
• Digital transparency enables data-driven asset management decisions, from energy use to ESG reporting.

Yes, the pilot in Winkel shows that only 15% of customers actively respond to dynamic tariffs. But that’s precisely where real estate owners come in. As stewards of housing and commercial space, you have the opportunity to integrate these systems behind the meter—automatically, silently optimizing, even when tenants don’t change behavior. In doing so, you’re not only relieving pressure from the grid, but unlocking long-term financial and environmental upside for your portfolio.

If you’re serious about sustainability, resilience, and tenant satisfaction, then you shouldn’t just watch these projects from the sidelines. You should ask: What would it take to deploy this kind of thinking across all my buildings?

The answer isn’t simple. But Winkel proves it’s possible.
