This summer, India peak power demand recently touched a massive 270 GW, driven by heatwaves, air-conditioning demand, industrial growth and data centres. 34% (roughly one-third) of that peak demand came from renewable energy, which points to a new challenge for India’s energy transition. The issue is not renewable power generation, but delivering that electricity to consumers when and where they need it.
 
Why solar alone isn’t enough
India is already adding solar capacity at a leading pace globally: in March-April 2026, India crossed the 150 GW milestone for installed solar capacity, adding a record-breaking 44.6 GW in a single financial year.
 
The problem is, solar generation is concentrated during daylight hours, but demand peaks during the evening hours from 6pm to 10pm, after solar output declines. This creates a growing mismatch between generation and consumption. The industry is now focusing on moving from intermittent generation to firm, dispatchable power and assured peak supply.
This is where solar power storage, wind energy and hybrid solar + wind power with energy storage (known as Firm and Dispatchable Renewable Energy or FDRE) become important.
 
The battery storage opportunity
With India’s growing solar capacity and the inconsistency between generation vs consumption Battery Energy Storage Systems (BESS) step in as a possible solution. By storing excess daytime electricity and discharging it during peak demand periods, batteries can help improve grid stability, reduce reliance on thermal energy, making solar energy available when consumers actually need it.
 
Industry experts such as BCG’s Vishal Mehta argue that storage is becoming a critical component of India’s energy transition, particularly as the country continues to add large amounts of solar capacity each year. Government agencies have also begun issuing large-scale storage tenders, signalling that battery deployment is moving from pilot projects to core grid infrastructure.
 
Two small caps stand out: one is Amara Raja Energy and Mobility. While best known for its automotive and industrial battery business, the company is readying itself for India’s next phase of energy storage growth. As solar capacity increases, grid-scale battery storage is expected to play a critical role in shifting excess daytime generation to evening peak demand periods. To capitalise on this opportunity, Amara Raja has announced significant investments across the lithium-ion value chain, including cell manufacturing, battery pack assembly, and advanced energy storage solutions.
 
The second is HBL Engineering, which has longstanding expertise in industrial batteries and energy storage-related technologies. This put it in a position to participate in emerging grid-storage opportunities.
 
Wind energy and FDRE
While solar power has dominated India’s renewable energy expansion, wind energy is becoming an increasing priority as the nation seeks more reliable green power beyond daylight hours. Unlike solar generation which peaks during mid-day, wind generation often complements solar by producing electricity during evenings, nights, and monsoon periods.
This makes wind particularly valuable in a power system increasingly challenged by the mismatch between daytime renewable generation and evening electricity demand.
 
Experts say that combining wind, solar and battery storage could significantly improve power output and reliability. This shift is giving rise to a new category of renewable projects known as Firm Dispatchable Renewable Energy (FDRE). Rather than relying on a single source of electricity generation, FDRE projects combine solar, wind and battery storage — and in some cases pumped hydro storage — to deliver electricity during specified time windows. The aim is not just  to generate renewable energy, but to make it available when customers actually need it, during peak hours. (The growing importance of FDRE can already be seen in government tenders and industry projects.) So instead of three separate competing technologies, under FDRE, solar, wind and batteries are being deployed as complementary parts of a single system designed to provide reliable green energy.
 
One smallcap that could benefit from this push is Inox Wind. The company manufactures wind turbine generators and provides project development and operation services. If India sees a sustained increase in wind installations as part of hybrid renewable and FDRE projects, demand for turbine manufacturing and related services could rise.
 
Another company to note is KPI Green Energy. The company develops renewable energy projects for both captive and independent power consumers and has expanded into hybrid renewable solutions (like wind solar hybrid power projects).
 
Making renewable energy readily available to consumers
India’s next energy growth cycle may look very different from the last one. The first phase was about building solar capacity. The next phase is about making renewable power available whenever consumers need it. As capital shifts toward storage, hybrid renewable systems, transmission networks and smart-grid technologies, a number of smaller listed companies could emerge as important beneficiaries of India’s energy transition and integration story.
