Featured Impact Story
Impact Story
Ampin Energy Transition (India)
India is the world’s third-largest electricity consumer and, as of 2024, the most populous country globally. Nearly 70% of its electricity generation remains fossil fuel-based, primarily coal, making India the third-largest greenhouse gas emitter worldwide. At the same time, the country has set ambitious targets: 500 GW of renewable energy capacity and a 50% non-fossil fuel share in power generation by 2030, and net zero emissions by 2070. The commercial and industrial (C&I) segment - accounting for nearly 50% of total electricity consumption - will be central to achieving these objectives.
Ampin Energy Transition Private Limited (Ampin), founded in 2016 and headquartered in New Delhi, is one of India’s leading renewable energy developers and operators focused on C&I customers. The company manages a diversified portfolio of 4.25 GWp of installed and development-stage capacity across key states including Karnataka, Rajasthan, and Andhra Pradesh. Its business model includes onsite solar installations, offsite renewable energy plants under long-term corporate power purchase agreements (PPAs), and hybrid solutions combining solar generation with battery storage.
One flagship asset is a 100 MW solar plant located in Bhadla Solar Park in Rajasthan, one of the largest solar parks globally, supplying clean electricity to corporate clients including Amazon India.
The Asia Climate Fund committed up to $35 million in senior private debt to finance the development and construction of new renewable energy assets under long-term corporate PPAs. The capital supports the scaling of offsite solar capacity for C&I customers and contributes directly to measurable emission reductions by displacing fossil-based power and accelerating decarbonization in industrial value chains.
In 2024, Ampin advanced new offsite solar deployments, expanded installed renewable energy capacity, and laid the foundation for significant lifetime CO₂ avoidance.
“This investment strengthens our mission to lead the transition to renewable energy for industrial and commercial clients,” said Pinaki Bhattacharyya, MD & CEO, Ampin Energy Transition.

Impact Story
CME Solar (Vietnam)
Vietnam’s rapid industrialization and export-led growth have driven strong increases in electricity demand, particularly from commercial and industrial (C&I) sectors such as electronics, garments, packaging, and food production. At the same time, global buyers are increasingly requiring greener supply chains, making rooftop solar an attractive solution for manufacturers seeking cost predictability and lower carbon footprints. Despite supportive policy momentum, local developers often face constraints in accessing long-term capital to scale distributed renewable energy assets.
CME Solar Investments (CME Solar), founded in 2019, is a leading rooftop solar developer in Vietnam providing solar-as-a-service solutions to C&I customers under long-term contracts. As of December 2025, the company had installed 150+ MWp of capacity and maintained an additional 50 MWp development pipeline. Its installations span key industrial provinces and include high-profile projects such as a 31.5 MWp rooftop plant for Foxconn in northern Vietnam.
CME’s model delivers cost-competitive renewable electricity to clients while ensuring alignment with international environmental and social management standards and maintaining a strong health and safety culture across project sites.
The Asia Climate Fund provided $7 million in long-term senior secured debt to finance the construction of additional rooftop solar systems for C&I customers. The investment builds on earlier financings from responsAbility-managed funds and supports further distributed renewable energy build-out across Vietnam’s industrial base.
All projects generate meter-based emission reductions at the point of consumption, replacing higher-emission grid electricity. Across the 50 MWp pipeline enabled by responsAbility’s capital, CME anticipates annual CO₂ savings of approximately 30,000 tons, alongside the issuance of Renewable Energy Certificates supporting clients’ climate commitments.
“Our partnership enables us to expand access to rooftop solar and accelerate Vietnam’s clean energy transition,” said Chung Dieu Tuan, CEO, CME Solar Investments.

Impact Story
Battery Smart (India)
India’s urban mobility system - dominated by two- and three-wheelers - contributes significantly to particulate emissions and local air pollution. A large share of vehicles operated by low-income commercial drivers continues to rely on internal combustion engines. Despite policy support for electric mobility, structural barriers persist, including high upfront vehicle costs, limited access to credit for informal-sector drivers, inadequate charging infrastructure, and long downtimes for recharging.
Battery swapping offers a practical solution to these constraints. It eliminates charging wait times, reduces total cost of ownership, and enables asset-light electrification for drivers with limited financial means.
Founded in 2019, Battery Smart has developed India’s largest battery-swapping network for electric two- and three-wheelers. The company operates more than 1,600 stations across over 35 cities and serves more than 100,000+ active users. Its decentralized, franchise-led model integrates local shopkeepers and micro-entrepreneurs as station partners, supporting community-level job creation while avoiding heavy centralized capex. Through its battery-as-a-service (BaaS) platform, users can exchange depleted batteries for fully charged units in under two minutes, maximizing vehicle uptime for drivers who earn on a per-trip basis.
In 2024, the Asia Climate Fund committed up to $25 million in private debt to finance the acquisition of lithium-ion batteries and related capex. The funding supports expansion into Tier 2 and Tier 3 cities, where infrastructure and financing gaps are more pronounced.
By facilitating electrification in underserved transport segments, Battery Smart contributes to the avoidance of CO₂ and black carbon emissions, reduction of local air pollutants (including PM2.5 and NOx), lower operating costs for drivers, and improved access to mobility and income opportunities.
“This investment helps us scale a model that brings EV infrastructure to communities where no other charging solution exists,” said Pulkit Khurana, CEO & Co-Founder, Battery Smart.
