Urban Energy Challenges: Securing Reliable Electricity and Fuel

India’s cities are growing fast, and so is their hunger for energy. From air conditioning in high-rise apartments to powering factories, hospitals, and transport networks, urban India’s electricity and fuel demands are surging at a pace that puts enormous pressure on an already strained energy system. The country’s installed power capacity now exceeds 440 GW, yet the challenge has shifted from simply generating enough electricity to delivering it reliably, affordably, and sustainably to its urban centres. Understanding these energy challenges – and the solutions being pursued – is essential for anyone studying urban environments.

India’s deep dependence on coal 🔗

Coal has been the backbone of India’s power system for decades, and despite massive renewable energy expansion, it still dominates. Coal contributes around 79% of India’s energy supply and roughly 60% of total primary energy supply. As of 2025, coal accounts for about 79% of the country’s electricity generation, with renewable energy sources still unable to match coal’s contribution. This heavy reliance exists because coal is abundant domestically, relatively cheap to extract, and provides the steady baseload power that variable renewable sources like solar and wind cannot yet guarantee around the clock.

For urban areas, this dependence comes with serious consequences. Coal-fired power plants are major contributors to air pollution, and Indian cities already rank among the most polluted in the world. India’s coal plants are still relatively young – on average, less than fifteen years old – meaning their natural retirement age is still decades away. Early closures would raise difficult questions about who absorbs the economic losses, making a rapid phase-out politically and financially complicated.

The erratic natural gas situation 🔗

Natural gas could serve as a cleaner transitional fuel between coal and renewables, but India’s domestic gas production has been inconsistent and insufficient to meet demand. The country imports a significant share of its natural gas, making supply vulnerable to global price fluctuations and geopolitical disruptions. India has recently expressed ambitions for greater consumption of natural gas as part of its broader energy transition strategy. However, the infrastructure needed to distribute gas widely across urban centres – pipelines, city gas distribution networks, and storage facilities – remains underdeveloped in many regions, limiting its practical role in addressing urban energy needs.

Why nuclear power hasn’t delivered 🔗

Nuclear energy offers reliable, zero-carbon baseload power, making it theoretically ideal for energy-hungry cities. But in India, nuclear power’s contribution remains small. Only about 7,300 MW of nuclear capacity is currently under construction, set against a long-term target of 100 GW by 2047 – raising doubts about whether nuclear can play a meaningful role in India’s energy future.

Several factors have held back nuclear expansion. Concerns about safety – especially after disasters like Fukushima – have fuelled public opposition to new plants near populated areas. Setbacks in India’s nuclear programme are multi-layered, reflecting both domestic and international challenges, including issues around uranium procurement and liability laws that have made foreign companies cautious about participating. The Council on Foreign Relations reports that India has recently passed legislation to open its nuclear sector to foreign investment, but actual progress in building new capacity has been slow. The Budget 2025-26 earmarked ₹20,000 crore for a Nuclear Energy Mission, signalling renewed ambition, but converting that into operational reactors will take years.

Challenges with renewable energy integration 🔗

India’s renewable energy story is genuinely impressive in terms of capacity growth. India added 41 GW of renewable energy in the first eleven months of 2025, a record for capacity additions, raising the share of renewables to 40% of the country’s installed capacity. Solar power has been the standout performer, with costs falling dramatically and installations scaling up rapidly across the country. But building capacity and actually delivering that power to urban consumers are two different things – and this is where the problems begin.

Land acquisition bottlenecks 🔗

Large-scale solar and wind farms need vast tracts of land, and securing this land in India is extremely difficult. Obtaining large, contiguous land parcels is particularly challenging due to fragmented landholdings, unclear ownership and title records, limited digitisation of land records, and lengthy approval processes. State-level land ceiling laws often prevent private players from acquiring large rural tracts, and competition for land from agriculture, urban development, and industry continues to intensify.

Additional renewable capacity remains stalled due to land acquisition challenges, unsigned power purchase agreements, equipment transport difficulties, and delays in transmission clearances. For wind energy projects, even transporting large turbine components through rural areas with limited road infrastructure has proved difficult. These are not just paperwork problems – they directly delay the clean energy that cities need.

Grid infrastructure falling behind 🔗

Even where renewable capacity has been built, the grid often cannot handle it. Between March and August 2025, Rajasthan experienced nearly 4 GW of solar and wind power curtailment due to transmission delays, corridor congestion, and subdued power demand during the monsoon season, causing financial losses estimated at ₹2.3-2.5 billion for developers.

Transmission infrastructure additions continue to lag behind renewable capacity growth, creating bottlenecks for grid integration, with less than 50% of the targeted transmission capacity for the first eight months of fiscal year 2026 having been completed. Lead times for critical high-voltage equipment have stretched to around 20 months, and transformer prices have more than doubled in recent years, increasing capital requirements for grid expansion.

Competition from international manufacturers 🔗

India is working to build domestic manufacturing capacity for solar cells, modules, and other renewable energy equipment. Solar module manufacturing capacity nearly doubled from 38 GW in March 2024 to 74 GW in March 2025, and solar cell manufacturing rose from 9 GW to 25 GW. The government’s Production-Linked Incentive (PLI) scheme has been a key driver of this growth.

However, the sector remains heavily exposed to global competition. India is 100% reliant on imports for essential minerals like lithium and cobalt, crucial for renewable energy technologies, and this dependency – particularly on China – exposes the sector to supply disruptions, price volatility, and geopolitical pressures. Chinese manufacturers dominate global production of solar cells and battery components, and shifts in their production priorities – such as moving from older PERC technology to newer TOPCon cells – have created supply shortages for Indian developers. Global trade dynamics, including tariff changes and redirected supply flows, add further uncertainty.

Addressing the urban energy deficit 🔗

Despite these challenges, India is pursuing several strategies to close the gap between urban energy demand and reliable supply. The solutions span technology, finance, and governance reform.

Solar power adoption in cities 🔗

Rooftop solar has emerged as a powerful tool for urban energy supply. The PM Surya Ghar: Muft Bijli Yojana programme promotes rooftop solar installations on residential buildings, enabling households to generate their own electricity and reduce dependence on the grid. As of October 2025, rooftop solar systems had reached 22.42 GW of installed capacity, showing increasing adoption among households, industries, and commercial establishments.

Solar installations on public buildings, airports, railway stations, and commercial complexes are also expanding rapidly. The falling cost of solar photovoltaic technology has made it one of the cheapest sources of new electricity in India. On India’s highest-demand day in 2025, solar generation alone contributed up to 60 GW during daytime peak hours, easing pressure on thermal plants. For cities experiencing peak demand during hot afternoons – exactly when solar output is highest – this alignment is a significant advantage.

Energy storage as the missing piece 🔗

Solar and wind power are intermittent – the sun sets, the wind drops. For cities that need electricity 24 hours a day, energy storage is critical to making renewables truly reliable. Utility-scale battery storage can typically be built and commissioned in 6-18 months, making storage the fastest lever to convert India’s growing solar and wind output into dependable evening and peak supply.

India’s battery storage pipeline is growing, though actual operational capacity remains limited. The country needs 74 GW of energy storage by 2031-32 but currently has only about 4 GW installed. Pumped hydro storage, which uses water reservoirs at different elevations to store and release energy, is another option, but these projects typically require around eight years to build. The rapid scale-up of battery storage will be essential for urban grid reliability in the coming decade.

Fixing the financial health of distribution companies 🔗

Perhaps the most critical but least visible challenge is the financial condition of India’s electricity distribution companies, or DISCOMs. These are the entities that buy power from generators and deliver it to end consumers, including urban households and businesses. DISCOMs have accumulated massive losses totalling over $74 billion, despite five government bailouts, driven by high technical and commercial losses, outdated metering systems, and persistent gaps between costs and the tariffs they can charge.

State-owned DISCOMs have accumulated over ₹6.77 lakh crore in losses by 2022-23, growing at roughly 7% annually since 2015, and have been taking on ever-increasing debt to cover these losses. This financial distress has real consequences for urban energy supply. Financially weak DISCOMs struggle to pay generators on time, cannot invest in infrastructure upgrades, and often resist signing power purchase agreements with renewable energy developers.

The government is tackling this through multiple measures. The Revamped Distribution Sector Scheme (RDSS) received an allocation of ₹160.21 billion in the Union Budget 2025-26 to support infrastructure upgrades and smart metering deployment, with over 224 million smart consumer meters sanctioned nationwide. Smart meters improve billing accuracy, reduce theft, and give DISCOMs better data for managing their networks. A new Draft Electricity Amendment Bill targets the structural problems that have plagued DISCOMs for decades, including procurement inefficiencies and tariff distortions.

Reducing transmission and distribution losses 🔗

India’s transmission and distribution losses fell to 17.6% in 2023-24, down sharply from over 30% in the mid-2000s – a major reform achievement. However, losses remain significantly above the global average of about 8%, and certain regions like the Northeast and northern India still report losses around 20%. Every unit of electricity lost in transmission is a unit that never reaches an urban consumer, so continued reduction in these losses is one of the most cost-effective ways to address the urban energy gap.

Investments in smart grids, regional interconnectivity, and digitalisation of distribution networks are all part of the solution. The focus has shifted from simply building more generation capacity to using existing capacity more efficiently and strengthening the last-mile delivery infrastructure that cities depend on.

The road ahead for urban energy 🔗

India’s urban energy challenge is fundamentally a balancing act. The country needs to keep the lights on in fast-growing cities while simultaneously transitioning away from polluting fossil fuels. India has set ambitious targets, aiming to install 500 GW of non-fossil capacity by 2030, enabling a grid that is nearly 50% clean. Achieving this will require addressing every link in the energy chain – from how power is generated and transmitted to how it is distributed and billed.

India’s power-sector challenge is no longer one of capacity adequacy but of system flexibility – lowering the minimum load of coal plants, rapidly scaling battery storage, and strengthening transmission networks are now essential to integrate rising renewable generation. For urban India specifically, rooftop solar, smarter distribution networks, and financially healthy DISCOMs will determine whether the energy transition delivers reliable power or creates new vulnerabilities.

The scale of investment required is enormous. Grid enhancement alone may need up to $150 billion, and renewable capacity additions will require $190-215 billion through the end of the decade. International partnerships, private sector investment, and consistent policy frameworks will all be needed to close this gap.

What do you think? Can Indian cities become self-sufficient in clean energy through rooftop solar and battery storage, or will coal remain indispensable for urban power supply well into the 2040s? How should the financial burden of modernising DISCOMs be shared between governments, consumers, and private investors?
