ABB Ltd and Boston Consulting Group Release Joint Brief on the Emerging Role of DC Power in Future Energy Systems
ABB Ltd (NYSE: ABB) has partnered with Boston Consulting Group (BCG) to publish a comprehensive research brief that examines how direct‑current (DC) technology is poised to reshape future power systems. The study, released on September 11, 2026, argues that the transition toward hybrid alternating‑current/direct‑current (AC/DC) architectures is driven by three interlocking forces: the explosive growth of artificial‑intelligence (AI) computing, accelerating electrification across all sectors, and the increasing penetration of renewable energy sources. While AC power will continue to be indispensable for long‑distance transmission and legacy infrastructure, DC power is expected to gain prominence inside industrial, commercial, and data‑center facilities—environments where many critical loads and energy sources already operate on DC.
Key Findings
| Theme | Insights | Implications |
|---|---|---|
| System Efficiency and Capacity | DC architectures reduce the number of conversion steps between generation, storage, and end‑use. This lowers conversion losses and expands the usable capacity of existing grid connections, allowing utilities to accommodate higher renewable shares without costly grid upgrades. | Utilities can achieve higher renewable integration targets more cost‑effectively, while equipment vendors can capitalize on the demand for DC‑compatible components. |
| AI Data Centers as Primary Drivers | The report identifies AI data centers as the most significant early adopters of DC power. It forecasts that 800‑volt DC distribution will become the benchmark architecture for next‑generation AI infrastructure, largely because it aligns with the power requirements of modern AI accelerators and offers higher reliability. | Data‑center operators must evaluate DC‑ready designs; vendors of power distribution, cooling, and IT equipment will need to align product lines with DC specifications. |
| High‑Automation Manufacturing & Commercial Buildings | DC power facilitates tighter integration of on‑site renewables, batteries, and electric‑vehicle charging stations, leading to lower conversion losses and improved energy‑efficiency metrics. | Manufacturers and building managers can realize energy‑cost savings and meet sustainability mandates by adopting DC‑based power solutions. |
| Long‑Term Building Applications | While the shift to DC in residential settings remains farther off, the brief highlights the potential for DC to streamline building‑level power distribution, especially when paired with distributed generation and storage. | Building‑owner associations and municipal regulators may consider incentives for DC‑ready construction in the coming decade. |
ABB’s Strategic Position
Morten Wierod, CEO of ABB, emphasizes that the widespread adoption of DC will hinge on coordinated action among industry players, policymakers, and technology providers. Key points from ABB’s perspective include:
- Industry‑Ready Portfolio – ABB boasts more than 700 DC‑related patents, spanning power electronics, converters, and control systems. Recent product milestones—such as the DC‑based onboard power system for vessels that achieved measurable fuel savings, and the solid‑state circuit breaker launched in 2022—demonstrate ABB’s technical leadership and commercial viability.
- Standards & Workforce Development – The company recognizes that fragmented standards and a shortage of skilled DC professionals remain the principal impediments to scaling. ABB is actively collaborating with standard‑setting bodies and educational institutions to promote common specifications and training pathways.
- Broad Application Spectrum – ABB’s research team is exploring DC applications across electric transport (e‑vehicles, ships), micro‑grids, data‑centers, low‑carbon aluminium smelting, and green hydrogen generation. These efforts underscore the cross‑industry relevance of DC technology.
Economic & Policy Context
The brief situates the DC transition within broader economic trends:
- Renewable Energy Cost Trajectories – As solar and wind costs continue to fall, the marginal cost of renewable generation approaches that of conventional baseload plants, increasing the value of efficient storage and power conversion solutions.
- AI‑Driven Workloads – The projected expansion of AI workloads is expected to double the global data‑center power demand by 2030. DC systems, by virtue of their higher power density and lower losses, can meet this demand more efficiently.
- Regulatory Momentum – Governments worldwide are tightening emissions targets and encouraging electrification of transport and industrial processes. The shift to DC power aligns with policy objectives aimed at reducing greenhouse gas emissions and enhancing grid resilience.
Conclusion
ABB’s joint brief with BCG underscores that DC technology, while not yet ubiquitous, offers clear advantages in specific high‑value contexts—particularly AI data centers, high‑automation manufacturing, and electrified transportation. The study dispels lingering misconceptions about DC scalability, safety, and economics, framing the main barriers as standards fragmentation and talent shortages. By fostering industry collaboration, investing in standardized solutions, and expanding its DC product portfolio, ABB positions itself to lead the transition toward hybrid AC/DC power systems that are more efficient, resilient, and aligned with the evolving needs of modern economies.
