From Energy to Intelligence: The Missing Electronic Layer in Industry 4.0/5.0 Strategy

India’s industrial transformation narrative is evolving rapidly. The language of Industry 4.0/5.0 now dominates policy discourses and public public discussions. The next phase of industrialization is to be driven by green energy, AI, automation, and digitally coordinated production and logistics systems. Factories are expected not only to be powered by green energy, but to operate as intelligent, adaptive systems.

This vision is directionally sound—but structurally incomplete.

The current discourse makes two conceptual leaps. The first, as I argued in a blogpost on 11 April, moves from renewable energy generation to industrial consumption, often overlooking the electrical infrastructure required to make power usable at scale. The second leap moves from powered systems to intelligent systems—without adequately accounting for the infrastructure that enables real-time control and responsiveness.

If electrical infrastructure forms the first missing layer in this transition, electronic infrastructure forms the second.

Two Missing Layers, Not One

Recent discussions around industrial transformation have rightly emphasised renewable energy expansion, grid modernisation, and lately, on electrification. However, even this foundational layer cannot yet be treated as a given.

Electrical systems remain under active strain:

- expanding demand from industry, mobility, and data centres

- integration challenges associated with renewable energy

- uneven quality of power supply across regions

- capacity constraints in transmission, distribution, and storage

In this context, electrical infrastructure continues to be a binding constraint—even as conversations move ahead to automation and AI.

Yet, the narrative has also advanced further. It now assumes that once power is available, intelligence can be layered seamlessly on top.

This assumption introduces a second gap.

Between powered systems and intelligent systems lies a distinct and critical layer: electronic infrastructure.

The Operating Layer of Modern Industry

If electrical infrastructure delivers power, electronic infrastructure determines how that power is used.

It includes:

- sensors that capture real-time data from machines and processes

- controllers (PLCs, DCS) that translate inputs into actions

- embedded systems that enable machine-level intelligence

- power electronics that regulate and optimise energy usage

- industrial communication systems that coordinate distributed operations

Together, these systems form the operating layer of modern industry. They do not merely support industrial processes, they define how those processes behave.

In effect: 

Electrical infrastructure converts energy into usable power.

Electronic infrastructure converts power into controlled, responsive, and adaptive industrial activity.

Why Industry 4.0/5.0 Cannot Bypass This Layer

Industry 4.0/5.0 is typically framed through technologies such as:

- Artificial Intelligence

- Industrial IoT

- digital twins

- predictive maintenance systems

All of these depend on certain underlying conditions:

- high-quality, continuous data flows

- real-time sensing and feedback

- precise and reliable control mechanisms

These conditions are not created by software alone. Without advanced electronic systems:

- sensors fail to capture accurate or timely data

- control systems respond with latency or inconsistency

- automation becomes fragile rather than resilient

- AI systems remain observational rather than operational

In such environments, intelligence exists in dashboards—not in the functioning of machines and systems.

This leads to a structural conclusion:

Industry 4.0/5.0 is not achieved by adding AI to industry. It is achieved by building the electronic infrastructure that allows systems to sense, decide, and act in real time.

The Design Frontier: Beyond Manufacturing

India’s recent progress in electronics has been driven largely by manufacturing expansion. Production-linked incentives, global supply chain shifts, and domestic demand have accelerated the growth of assembly and system manufacturing.

This progress is necessary—but not sufficient.

The next frontier lies in design. Design determines:

- system architecture

- control logic

- performance limits

- interoperability across systems

- integration pathways for AI and digital technologies

Manufacturing scales production.

Design determines control.

When electronic systems are designed externally, the behaviour of industrial systems is effectively defined outside the domestic ecosystem. Local manufacturing, in such cases, does not translate into full technological capability.

By contrast, domestic design capability allows:

- adaptation to local industrial conditions

- integration across sectors

- development of proprietary systems

- deeper alignment between infrastructure and application layers

In the context of Industry 4.0/5.0, design is not a peripheral capability. It is the basis of technological agency.

Contract Manufacturing: Constraint or Pathway?

The current expansion of electronics manufacturing in India is often framed through the lens of contract manufacturing. 

At one level, this model involves producing systems designed elsewhere—limiting domestic control over architecture and functionality.

However, contract manufacturing need not be a terminal state. Globally, it has often functioned as a capability ladder:

- manufacturing builds process discipline and scale

- engineering support introduces design interaction

- co-development enables system-level understanding

- eventual product development builds proprietary capability

The distinction, therefore, is not between manufacturing and design—but between static manufacturing and progressive capability building.

Contract manufacturing can lock an ecosystem into execution, or, it can serve as an entry point into design.

The outcome depends on whether it is accompanied by deliberate investments in engineering, R&D, and system architecture.

Control, Capability, and Sovereignty

Industrial electronics is not just a technical domain—it is a strategic one.

Global industrial technology companies like such as Siemens, Schneider Electric, Honeywell, and Rockwell Automation have built enduring positions in this space (and each of them have substantial manufacturing operations in India). 

Their strength does not lie only in manufacturing equipment. It lies in designing and controlling the architectures that govern industrial systems:

- automation frameworks

- control platforms

- industrial communication protocols

- system integration standards

These architectures determine how factories operate, how grids respond, and how industrial systems evolve over time.

In this sense, control over industrial electronics is, in effect, control over how industry functions.

Toward Domestic Capability: A Recent Signal

Yesterday, L&T announced that it is entering the B2B industrial electronics space with the commencement of industrial electronics manufacturing at its Coimbatore facility. The new business vertical, christened L&T Electronic Products & Systems (LTEPS), will be headquartered in Bengaluru, while the manufacturing operations will be based in Coimbatore. To begin with, two manufacturing lines have been commissioned, offering electronics manufacturing services to both Indian and global clients. The company will adopt a blended approach of in-house R&D, technology partnerships and advanced testing infrastructure to deliver market-ready solutions.

This initiative creates the possibility of:

- learning through manufacturing

- building engineering depth

- progressing toward system design

- product development

It is too early to assess outcomes. But the direction is notable. It indicates an understanding that:

- industrial competitiveness increasingly

depends on electronic systems

- long-term capability requires participation in design, not just production

- manufacturing can serve as a foundation for deeper technological development

Whether this evolves into sustained design capability remains an open question. But it represents a shift from pure execution toward potential architectural participation.

Reconstructing the Industrial Stack

Taken together, industrial transformation can be understood as a layered system:

- Energy generation

- Electrical infrastructure → enables reliable and scalable power

- Electronic infrastructure → enables control, coordination, and responsiveness

- AI and digital systems → enable optimisation, learning, and adaptation

Each layer builds upon the previous one.

Underdevelopment in any layer weakens the entire system:

- energy without electrical systems remains unusable

- power without electronic systems remains uncontrolled

- control without AI remains unoptimised

Industry 4.0/5.0 is not a single technological shift. It is the integration of all these layers into a coherent system.

India’s Moment: Partial Stack or Full Capability?

India stands at a critical juncture:

- expanding industrial base

- rising electricity demand

- increasing digital and AI ambitions

- growing electronics manufacturing ecosystem

This creates both opportunity and risk.

The opportunity lies in building a full-stack industrial capability—spanning energy, electrical systems, electronics, and AI.

The risk lies in developing a partial stack:

- domestic manufacturing

- imported control systems

- externally defined architectures

- AI layered on top

Such a model creates intelligent systems built on foundations that are not fully controlled. In other words, it enables adoption—but limits autonomy.

Conclusion: From Power to Intelligence

Industry 4.0/5.0 is often presented as a transition driven by software, data, and AI.

In reality, it is a deeper transformation—grounded in infrastructure.

Electrical systems ensure that power is available, reliable, and scalable.

Electronic systems ensure that this power is directed, controlled, and translated into action.

AI builds on this foundation—but cannot substitute for it.

If the first requirement of industrial transformation is electrification, the second is electronification—the embedding of intelligence into the physical operation of systems.

The future of industry will not be determined solely by how much power is generated, or how advanced algorithms become. It will be determined by how effectively nations build, design, and integrate the layers that connect energy to intelligence.

Nations that recognise only the visible layers may modernise. But those that build and control the underlying layers will define how modern industry operates.
