The traditional energy model—centralized, fossil-fueled, and AC-dominated—is no longer sufficient. The rise of renewables, electric vehicles, data centers, and prosumer buildings is creating new demands on our infrastructure. At the same time, grid congestion, energy losses, and e-waste are becoming critical challenges.
On the other hand, we witness a powerful insight: Direct Current (DC) is already all around us. From solar panels and batteries to smartphones and EV chargers, most modern technologies operate natively on DC. Yet, we continue to rely on AC infrastructure, leading to inefficiencies and unnecessary conversions.
The new energy landscape demands new solutions. This white paper “Connecting Alternating Current (AC) with Direct Current (DC) – The Future of Energy Transition” highlights how the hybrid AC/DC distribution can power the energy transition.
Why DC? Why now?
This white paper outlines several compelling reasons why now is the time to embrace DC as a core part of our energy strategy:
- Efficiency Gains: Every AC/DC conversion results in energy loss. By using DC where it makes sense—such as in lighting, EV charging, and renewable integration—we can reduce losses by up to 30%.
- Material Savings: A recent DC microgrid project in the Netherlands demonstrated a 50% reduction in cabling, lowering both costs and environmental impact.
- Faster Deployment: Projects using DC microgrids have seen faster utility approvals, cutting wait times from years to months.
- Resilience and Flexibility: DC systems enable decentralized control, making it easier to scale and adapt to changing energy needs—especially in buildings and campuses.
Hybrid microgrids: The best of both worlds
Rather than replacing AC, the white paper advocates a hybrid approach. AC remains essential for long-distance transmission and legacy systems. But DC offers unmatched advantages for local generation, storage, and consumption.
This hybrid model is especially powerful in prosumer environments—buildings that both consume and produce energy. By integrating DC into their infrastructure, prosumers can:
- Optimize the use of onsite renewables like solar PV and fuel cells
- Reduce reliance on the grid and improve energy independence
- Enable smart, self-regulating systems, for example using the Current/OS
- Lower operational costs and carbon emissions
Buildings of the future: Powered by DC
The white paper envisions a future where buildings are fully electrified, self-sufficient, and digitally intelligent. DC plays a central role in this vision:
- Commercial buildings can use DC to power lighting, elevators, and heat pumps more efficiently.
- Data centers benefit from improved power quality and reduced conversion losses.
- EV infrastructure becomes more scalable and cost-effective with DC charging.
Real-world examples, such as Vinci’s Energies regional headquarters and the N470 sustainable road project in the Netherlands, show that DC integration is not just theoretical—it’s already delivering measurable results.
Overcoming barriers: Education, standards, and innovation
Despite its advantages, DC adoption still faces hurdles: lack of awareness, outdated regulations, and limited technical expertise. That’s why Schneider Electric is committed to:
- Educating the market through white papers, training, and demonstration projects
- Collaborating with regulators to develop DC-friendly standards
- Innovating with new technologies, such as the InterLink Converter, which seamlessly connects AC and DC systems
