India is staring down a climate emergency that most of its citizens are already living through. The 2026 El Nino has pushed monsoon rainfall 42 percent below normal in large parts of the country. Temperatures above 45 degrees Celsius have been recorded across northern and central India. Electricity demand has surged past 240 gigawatts as cooling loads climb. Reservoirs are depleted. Agricultural output is under severe pressure. And according to climate models, the 2026-27 El Nino could be the strongest event in 140 years. Follow every India startup and climate tech story at BestStartup India.
Against that backdrop, a generation of Indian founders is building the clean energy and climate technology infrastructure that India needs not just to meet its net zero targets but to survive the next decade of climate stress. India’s climate tech startups have raised $12.8 billion across 1,583 companies since 2008. Annual funding grew from $315 million in 2020 to $2.6 billion in 2025. In Q1 2026 alone, Indian climate tech startups raised $1.4 billion. These are the ten startups at the centre of that story.
Why El Nino Is the Moment Indian Climate Tech Has Been Building For
El Nino years create the conditions in which climate technology shifts from aspiration to operational necessity. When monsoon rainfall drops 42 percent below normal, every gigawatt of solar capacity that was installed in the preceding years becomes a grid lifeline rather than a policy achievement. When temperatures hit 45 degrees, every battery-swapping station that keeps electric delivery vehicles running through a summer that would have killed a petrol engine becomes a competitive advantage. When electricity demand hits 240 gigawatts and hydropower generation falls because reservoirs are low, the startups that built grid storage, fast-charging networks and energy management software find that every utility operator in the country wants to speak with them.

Simple Energy — Bengaluru
Simple Energy raised Rs 1,750 crore in a Series C on September 30 2026, taking its total funding to over Rs 2,530 crore. The Bengaluru electric two-wheeler manufacturer makes the Simple One scooter, which at launch held the record for the longest range of any electric scooter sold in India at 212 kilometres on a single charge. Its founder Suhas Rajkumar started the company in 2019 and has built one of the few Indian EV companies with genuinely differentiated battery management technology developed in-house. The Rs 1,750 crore Series C is the largest single fundraise by an Indian electric two-wheeler company in 2026 and positions Simple Energy as a direct rival to Ola Electric and Ather for India’s 21 million annual two-wheeler market.

Battery Smart — Delhi
Battery Smart operates India’s largest battery swapping network for electric three-wheelers and commercial vehicles. Its model solves one of the most stubborn barriers to EV adoption in India: the upfront cost of the battery, which typically accounts for 40 to 50 percent of an electric vehicle’s purchase price. Battery Smart’s drivers buy or lease vehicles without batteries and subscribe to battery swaps at stations across its network, replacing a depleted pack in under three minutes. Investors including Tiger Global, British International Investment, LeapFrog Investments, MUFG Bank and Panasonic have contributed over $192 million. In an El Nino year where extreme heat degrades battery performance faster than normal, Battery Smart’s ability to replace worn packs instantly rather than waiting for charging cycles becomes operationally critical for every commercial EV fleet it serves.

Ather Energy — Bengaluru
Ather Energy is the most technically sophisticated electric two-wheeler manufacturer in India. Co-founded by Tarun Mehta and Swapnil Jain, both IIT Madras graduates, Ather builds its scooters, battery packs, charging network and vehicle operating system entirely in-house. Its Ather 450X and 450 Apex have consistently received the highest real-world range and performance ratings of any Indian electric scooter in independent testing. Ather went public in 2025 and has used its listed status to accelerate manufacturing scale at its Hosur facility in Tamil Nadu, which is capable of producing over a million vehicles annually. Its AtherGrid fast-charging network has become the benchmark for public EV charging infrastructure quality in India, with over 2,200 charging points across more than 160 cities. In an El Nino summer where temperatures push beyond 45 degrees, Ather’s proprietary thermal management system inside its battery packs is one of the few in the Indian market designed specifically to maintain performance under extreme heat conditions.
Exponent Energy — Bengaluru
Exponent Energy has built a 15-minute full charge technology for commercial electric vehicles — a capability that most battery engineers said was impossible without compromising battery life. Its e-pump technology and battery management system enable 0 to 100 percent charging in 15 minutes repeatedly without the degradation that kills conventional fast-charged batteries after a few hundred cycles. The company raised a total of $65.7 million including a Rs 200 crore investment led by TDK Ventures and 360 ONE Asset in June 2026. Its technology has progressed from 10 kilowatt-hour packs for electric three-wheelers to 420 kilowatt-hour systems for electric buses, including India’s first all-sleeper electric bus fleet. In an El Nino year where electricity demand is surging and grid operators need flexibility, Exponent’s fast-charging systems enable commercial fleets to charge during off-peak demand windows rather than requiring overnight charging that competes with peak grid load.

Log9 Materials — Bengaluru
Log9 Materials is India’s most advanced battery chemistry startup. Founded by Akshay Singhal and Kartik Hajela, the company develops lithium iron phosphate and multivalent battery chemistries that are specifically optimised for Indian operating conditions: extreme heat, high discharge cycles from stop-start urban driving and the wide temperature range between Indian summers and northern winters. Log9 holds multiple patents on its battery formulations and has commercial contracts with fleet operators, logistics companies and EV manufacturers including Euler Motors. Its battery management software monitors cell-level health in real time, enabling predictive maintenance that fleet operators use to prevent battery failures before they ground vehicles during peak summer periods when every EV on the road is under maximum thermal stress from El Nino-amplified heat.

Euler Motors — Delhi
Euler Motors builds electric commercial vehicles for last-mile logistics. Its HiLoad electric three-wheeler is the highest-payload electric cargo vehicle in its category in India, capable of carrying 688 kilograms on a single charge of 151 kilometres. Its customers include Swiggy, Zepto, Porter, Amazon and Shadowfax — the companies running India’s quick-commerce delivery networks that have seen demand surge during El Nino summers as consumers avoid outdoor heat by ordering everything online. British International Investment has backed Euler alongside Blume Ventures and Navam Capital. The company’s focus on commercial rather than consumer EVs gives it structural revenue resilience: fleet operators commit to multi-year contracts and volume commitments that consumer EV manufacturers cannot access.
Inox Clean Energy — Gujarat
Inox Clean Energy raised $344 million in a Series D in 2026, making it one of the largest single fundraises in Indian clean energy history. The Gujarat-based company develops wind energy projects across India, with a particular focus on hybrid wind-solar projects that provide more consistent power generation than either technology alone. Its hybrid approach is directly relevant to El Nino conditions: cloud cover from monsoon systems reduces solar yield at exactly the times when wind speeds are highest, while El Nino’s monsoon suppression increases solar irradiance at the expense of wind. A hybrid portfolio hedges both. Inox’s Series D positions it to accelerate project commissioning as India races to add renewable capacity in response to the electricity demand surge that El Nino has triggered.

Ultraviolette — Bengaluru
Ultraviolette raised $85 million in September 2026 led by Yali Capital and TDK Ventures with Intel CEO Lip-Bu Tan investing personally. The Bengaluru electric motorcycle maker builds the F77 and X-47, which are India’s highest-performance electric motorcycles and the first production two-wheelers in the country to incorporate radar-based active safety systems. With 70,000 paid bookings for its upcoming Tesseract scooter and Shockwave light motorcycle, Ultraviolette has validated commercial demand at a scale that puts it in a different category from most Indian EV startups. It already sells across 10 European Union countries and is targeting the United States in 2027. In an El Nino year, its radar-based safety system becomes even more valuable as extreme heat creates road surface conditions and driver fatigue patterns that increase accident risk.

Chakr Innovation — Delhi
Chakr Innovation builds emission control and air quality technology for diesel generators and industrial equipment. Its flagship product captures particulate matter from diesel generator exhausts and converts it into ink, paint pigment and other materials — a circular economy approach that simultaneously reduces air pollution and creates commercial value from waste. In El Nino years when electricity grid stress forces more backup diesel generator use across India’s commercial and industrial sector, Chakr’s technology becomes more commercially relevant with every grid outage. The company reported FY24 revenue of approximately Rs 125 crore and net profit of Rs 9.5 crore, making it one of the few Indian climate tech startups operating profitably at meaningful revenue scale.

Yulu — Bengaluru
Yulu operates India’s largest shared electric micro-mobility fleet in cities including Delhi, Bengaluru and Mumbai. Its single-seat electric two-wheelers are available for short-duration hire through its mobile application and serve the first-mile and last-mile connectivity gap between metro stations, bus stops and final destinations. In an El Nino summer where urban heat islands push city temperatures well above ambient levels, Yulu’s zero-emission vehicles contribute meaningfully to reducing the exhaust heat that diesel and petrol two-wheelers add to India’s already overheated urban environments. The company plans to expand its fleet to over one lakh electric two-wheelers, backed by investors including Rocketship.vc, Blume Ventures and mobility specialist backers who see shared micro-mobility as structurally important for India’s urban transport decarbonisation.

Why India’s Climate Tech Moment Has Arrived
El Nino 2026 is not just a weather event. It is the forcing function that is turning India’s clean energy transition from a long-term policy ambition into an immediate operational imperative. When monsoon rainfall is 42 percent below normal, when temperatures hit 45 degrees, when electricity demand surges past 240 gigawatts, the argument for clean energy investment stops being about climate commitments and starts being about national resilience. The ten companies above are building that resilience. India’s climate tech sector has raised $12.8 billion since 2008. Q1 2026 alone saw $1.4 billion deployed. The pace is accelerating exactly when the climate need is most acute. That alignment of capital and urgency is what makes India’s climate tech sector one of the most significant investment stories in global clean energy today.
