Distribution Revamp: Recent advances and key trends

The operations of power distribution utilities are poised for significant transformation in the coming years, driven by evolving customer demands and shifts in the energy landscape. The increasing adoption of renewable energy, the proliferation of rooftop solar systems and electric vehicles, the need for network upgrades and enhanced consumer engagement, and the intensifying competition in the power supply segment are compelling utilities to rethink their business models. These changes are expected to prepare utilities for higher load growth and a future with greener energy.

A critical area is the deployment of smart meters under the government’s flagship revamped Distribution Sector Scheme (RDSS). Further, the adoption of advanced grid technologies is set to accelerate as discoms invest in solutions such as artificial intelligence (AI)-based applications, predictive analytics, GIS mapping, drone monitoring, data analytics and digital twins. A look at the emerging trends and developments shaping the power distribution segment…

State of the segment

Serving as the final and most critical link in the electricity supply chain, the distribution segment directly caters to consumers. Currently, the distribution segment serves approximately 250 million consumers through 73 state and union territory (UT) licensees, 13 private distribution companies and eight franchisees.

India has achieved 100 per cent household electrification and near-24-hour electricity supply, driven by initiatives such as the Integrated Power Development Scheme, Deen Dayal Upadhyaya Gram Jyoti Yojana and Ujwal Discom Assurance Yojana.

In terms of operational performance, discoms have made notable progress. The gap between the actual cost of supply and the approved revenue requirement has significantly reduced, declining from Re 0.63 per kWh in FY2021 to Re 0.21 per kWh in FY2024. Similarly, aggregate technical and commercial losses have improved, dropping from 21.9 per cent in FY2021 to 17.6 per cent in FY2024.

These improvements can be attributed to several factors, including the elimination of new regulatory assets, timely issuance of tariff orders, full payment of subsidies and a reduction in dues owed to power generation companies.

That said, the financial performance of discoms remains weak, with their operations heavily reliant on loss takeovers by state governments. Accumulated losses reached Rs 6,767 billion in FY2023, primarily due to unrecovered tariffs. Rising debt levels, driven by operational inefficiencies and the need for working capital, have increased significantly from Rs 4,761 billion in FY2019 to Rs 6,612 billion in FY2023.

Revenue gaps in discoms are exacerbated by regulatory disallowances in tariff petitions by state electricity regulatory commissions. Additionally, a heavy dependence on subsidies, which constituted 18 per cent of the total revenue in FY2023, leaves discoms vulnerable to policy shifts. Furthermore, billing efficiency has stagnated at approximately 85 per cent, underscoring the need for significant improvement in this area.

Significant reforms are being implemented in the segment to address key challenges. The Late Payment Surcharge Rules have reduced overdue payments, bringing them down from Rs 1,295.84 billion in September 2022 to Rs 372.78 billion in February 2024. The Electricity Amendment Rules 2024 introduced several measures, such as collective responsibility for discoms, time-of-day tariffs, revised charges and mechanisms to strengthen financial stability. Further, the Ministry of Power has introduced new financial accounting and disclosure rules for discoms, aimed at improving transparency, accountability and operational efficiency.

In terms of forecasts, the CEA’s Distribution Perspective Plan estimates an investment of Rs 7.42 trillion in the distribution segment from 2022 to 2030. To cater to the projected 520 million consumers by 2030, the plan outlines significant network additions for substations, feeders, capacitor banks and distribution transformers (DTs).

Smart metering

Smart meters have a significant role to play in making the grid smarter and more flexible. One of the major initiatives that the central government has undertaken is to mandate the adoption of smart meters across India. Reportedly, as many as 250 million smart meters are being installed. Under the RDSS, which was launched to support the states/UTs to improve the operational efficiencies and financial sustainability of distribution utilities, smart metering has been identified as a key initiative.

Smart meters and AMI present new opportunities beyond energy consumption measurement, such as monitoring voltage for distributed energy resource-rich grids, and analysing power quality and harmonics.

According to the National Smart Grid Mission dashboard, as of January 2025, out of the 222.35 million meters that have been sanctioned, 19.18 million meters have been installed. The top five states in terms of smart meters installed so far are Bihar, Assam, Uttar Pradesh, Madhya Pradesh and Punjab.

In the case of DT metering, 5.29 million meters were sanctioned, out of which 0.32 million have been installed, leaving 4.97 million pending. Leading states for installed DT meters include Uttar Pradesh, Tamil Nadu, Madhya Pradesh, Rajasthan and Maharashtra.

Similarly, for feeder metering, 0.21 million meters were sanctioned, with 0.08 million installed and 0.12 million still to be rolled out.

Emerging technologies

The utility sector is transforming through digitalisation efforts, integrating technologies such as smart metering and edge computing to enhance operations and customer service.

Advanced distribution management systems are being widely implemented to automate outage recovery, optimise voltage, manage peak demand, and support emerging technologies such as electric vehicles (EVs) and microgrids. Real-time data acquisition systems serve as cost-effective alternatives to SCADA systems, offering real-time data collection in smaller towns, improving network reliability and enabling proactive measures to reduce power interruptions.

AI and ML are transforming grid management by analysing sensor data for predictive maintenance and load forecasting, and optimising power distribution, in turn, reducing unplanned downtime. Blockchain technology is revolutionising energy transactions, enabling secure, transparent peer-to-peer trading, renewable energy certificate trading and virtual power plants.

Digital twin platforms are helping utilities replicate physical assets such as substations, transformers and distribution lines virtually, and facilitate simulation of different operating scenarios, performance assessment, and optimisation for enhanced asset utilisation and longevity. Augmented reality and virtual reality are improving operational efficiency, training programmes and maintenance activities by providing immersive, hands-on learning and situational awareness, helping workers manage emergencies and improve infrastructure interaction.

Further, paving the way for smart power distribution, under the RDSS, Varanasi City has been selected for a pilot project to assess the effectiveness of various technologies. The anticipated benefits include self-healing grids, enhanced power reliability, improved asset management, seamless renewable energy integration and greater consumer control over energy consumption.

Utilities are also aiming to enhance customer interactions by implementing innovative technologies such as voice bots and interactive platforms such as WhatsApp, mobile applications and web portals.

Challenges and outlook

A key challenge that has arisen due to the increased adoption of technology is data privacy and cybersecurity. There is a pressing need for utilities to proactively address cybersecurity vulnerabilities. Robust IT systems must be underpinned by comprehensive policies, particularly focusing on cybersecurity, in line with guidelines issued by the Ministry of Electronics and Information Technology, the CEA and the Indian Computer Emergency Response Team.

Further, as EV adoption grows, utilities must also proactively manage grid loads and customer interactions to ensure reliability and resilience. Another critical challenge faced by utilities in automation and digitalisation is the lack of sufficient broadband wireless infrastructure for real-time monitoring and control.

Addressing these challenges requires substantial investments in consumer interfaces, process optimisation and future-ready networks. Strengthening in-house IT capabilities, revisiting organisational structures and achieving operational standards comparable to global utilities are essential.

Building a robust and sustainable power distribution network also involves modernising grid infrastructure through initiatives such as underground cabling and advanced monitoring systems. Equally important is ensuring the financial stability of discoms by effectively managing their debt, implementing timely and appropriate tariff revisions, strengthening governance frameworks and improving operational efficiency.
