Grid Modernisation, Cybersecurity and Technology Indigenisation Under Draft NEP 2026

Introduction: The Digitising Grid

India's electricity grid is undergoing rapid digitalisation. Smart meters are being deployed by the millions. Solar generation forecasting relies on satellite data and machine learning. Grid control centres use sophisticated energy management systems. Power markets operate through electronic platforms. And the integration of millions of distributed solar panels, battery systems, and electric vehicles requires real-time data exchange across the network.

This digitalisation creates enormous efficiencies — but it also creates new vulnerabilities. A sophisticated cyberattack on a grid control system can cause blackouts affecting millions of people. Data breaches from smart meters can expose sensitive consumer information. Foreign-made critical grid components may contain security vulnerabilities or backdoors. Dependence on foreign software for grid operations creates strategic risk in the event of geopolitical tensions.

The Draft National Electricity Policy (NEP) 2026 addresses these realities with a set of grid modernisation, cybersecurity, and technology indigenisation provisions that are among the most forward-looking aspects of the policy.

Data Sovereignty: Keeping Power Sector Data in India

NEP 2026 mandates mandatory storage of power sector data within India, as a measure to ensure data sovereignty and system resilience.

This provision reflects a growing consensus in Indian regulatory policy that critical infrastructure data — whether financial, telecommunications, or electricity-related — should not be stored on foreign servers where it is subject to foreign jurisdiction and potentially accessible to foreign intelligence agencies.

For the electricity sector, the data in question includes:

Consumer consumption data from smart meters — granular records of when and how much electricity each consumer uses, which can reveal personal and commercial behaviour patterns
Grid operational data — real-time data on power flows, frequency, and voltage across the transmission and distribution network
Market data — pricing, trading, and settlement data from electricity exchanges and bilateral markets
Forecast data — renewable generation forecasts, demand forecasts, and weather data used in grid planning

The mandate for domestic data storage will require cloud service providers, technology vendors, and system integrators working with DISCOMs and grid operators to ensure that data processing and storage infrastructure is located in India.

Data Sharing Framework

NEP 2026 also proposes a framework for sharing operational and market data among sector participants. This is the complementary obligation to data sovereignty — data that is kept in India should be accessible to those who need it for legitimate operational purposes. The policy envisions:

Real-time visibility of Distributed Energy Resources (DERs) — solar panels, batteries, EV chargers — to DISCOMs and SLDCs
Open data frameworks for market transparency and monitoring
Standardised protocols for data exchange between market participants

SCADA Indigenisation: Replacing Foreign Systems by 2030

The most technically specific and operationally consequential provision is the mandate for transition to indigenously developed SCADA systems by 2030.

What is SCADA?

SCADA (Supervisory Control and Data Acquisition) systems are the software platforms that grid operators use to monitor and control the electricity network in real time. They collect data from sensors and meters across the grid, display it to operators on control room screens, enable remote control of switches and breakers, and automatically respond to grid disturbances.

SCADA systems are the "central nervous system" of the electricity grid. A compromise of a SCADA system — whether through cyberattack, software vulnerability, or hardware backdoor — can give an adversary the ability to cause widespread grid failure.

The Strategic Risk of Foreign SCADA

Most SCADA systems currently deployed in India's power sector — at POSOCO (the national grid operator), the regional transmission utilities, and many DISCOMs — were procured from foreign vendors, primarily from Europe, the US, and historically from China. These systems may contain:

Security vulnerabilities that are discovered and exploited by malicious actors
Backdoors deliberately inserted by equipment manufacturers or their governments
Dependencies on foreign software updates and support that create strategic leverage

The 2020 cyberattack on Mumbai's power grid — which caused a major blackout — was attributed to foreign state-sponsored actors and highlighted the vulnerability of Indian critical infrastructure to sophisticated cyber operations.

The 2030 Mandate

NEP 2026 mandates the transition to indigenously developed SCADA systems by 2030 for all critical power system applications. This is an ambitious target — SCADA systems are complex, deeply embedded in grid operations, and typically have 15-20 year lifecycles. Replacing them requires:

Development of domestic SCADA software with capabilities equivalent to foreign systems — this requires significant R&D investment, likely through public sector research institutions and private sector technology companies
Rigorous testing and certification of domestic systems before deployment in critical grid operations
Phased migration plans for individual utilities, with legacy system support during the transition
Workforce training for grid operators on new systems

The Ministry of Electronics and IT (MeitY) and the Ministry of Power will need to collaborate closely to develop the indigenous capability required for this transition.

Development of Domestic Software for Critical Power Applications

Beyond SCADA, NEP 2026 calls for the development of domestic software solutions for all critical applications in the power system. This includes:

Energy Management Systems (EMS) — used by transmission operators for network monitoring and control
Distribution Management Systems (DMS) — used by DISCOMs for distribution network operations
Advanced Metering Infrastructure (AMI) — software platforms for smart meter management
Market Management Systems — platforms used by electricity exchanges and power procurement agencies
Weather and generation forecasting systems — critical for renewable integration

The indigenisation of these systems serves both cybersecurity and economic goals — reducing import dependence, building domestic capability, and creating export opportunities as India becomes a technology supplier to other developing country electricity sectors.

Cybersecurity Framework

NEP 2026 envisions a strong regulatory framework for market monitoring and surveillance to prevent:

Collusion among market participants — such as coordinated bidding to manipulate electricity prices
Gaming — exploiting market rules to extract payments without providing genuine services
Market dominance — abuse of dominant position by large generators or traders

The cybersecurity provisions complement these market integrity requirements. A secure grid is not just about physical resilience — it requires data integrity so that market signals are accurate and cannot be manipulated.

Real-Time Visibility of Distributed Energy Resources

As millions of solar panels, batteries, and EV chargers connect to India's distribution networks, SLDCs and DISCOMs face a growing challenge: they have limited visibility of what these devices are doing. A distributed solar panel that trips unexpectedly, or a cluster of EV chargers that all start charging simultaneously, can affect grid frequency and voltage — but currently, grid operators often cannot see these events in real time.

NEP 2026 requires real-time visibility of Distributed Energy Resources (DERs) to DISCOMs and SLDCs. This requires:

Smart inverter standards that enable DERs to communicate with grid operators
DER Management Systems (DERMS) — software platforms that aggregate and process DER data
Communication infrastructure — the data connectivity linking DERs to control centres

The DSO concept proposed in NEP 2026 is the organisational vehicle for managing this real-time DER visibility at the distribution level.

Transmission Technology: Addressing Right-of-Way Challenges

Grid modernisation extends to transmission infrastructure. NEP 2026 proposes:

Adoption of latest technologies for transmission, including High-Voltage Direct Current (HVDC) lines for long-distance bulk power transfer and Gas-Insulated Substations (GIS) for urban areas with limited space
Suitable compensation for land use to address Right-of-Way (RoW) challenges that currently cause significant delays in transmission line construction
Parity of transmission tariff with conventional power by 2030 for all types of new renewable energy capacity

Assessment: Ambition Matched by Resources?

The grid modernisation and cybersecurity provisions of NEP 2026 are technically sound and strategically well-motivated. The data sovereignty mandate, SCADA indigenisation programme, and DER visibility requirements are all appropriate responses to real risks.

The critical question is whether the ambition is matched by the resources and organisational capacity required for implementation. Developing world-class SCADA systems domestically by 2030 is a major engineering and software challenge. It requires sustained R&D investment, access to top engineering talent, and a procurement framework that gives domestic developers access to testing environments in real grid operations.

This challenge is not unprecedented — India has successfully built domestic capability in space technology, defence electronics, and nuclear power. But it requires a deliberate, well-funded programme rather than an aspirational target in a policy document.

Conclusion

The grid modernisation and cybersecurity provisions of NEP 2026 reflect a sophisticated understanding of the strategic and operational challenges facing India's electricity sector in an increasingly digital, distributed, and interconnected energy system. The SCADA indigenisation mandate in particular represents a significant national security priority. Its implementation over the next four years will be one of the most technically demanding aspects of the policy's execution.
