The Energy Company (TEC) is a Bengaluru-based energy storage and battery technology provider founded in December 2021 by Rahul Lamba, Pratik Somani, Vinay Karulkar, and Prashant Rathee. The company began by developing battery packs for electric two-wheelers and e-rickshaws before expanding into commercial and industrial energy storage systems designed to replace diesel generators, and later into residential battery storage with grid-interaction capabilities.
TEC describes itself as an energy storage infrastructure company rather than solely a battery manufacturer, combining hardware, software, and power electronics to address reliability gaps in India’s electricity grid, including solar curtailment and diesel dependence in commercial and industrial operations. Its technology stack includes a digital identity and lifecycle-tracking framework for batteries, an AI-based monitoring and management platform, and load-prioritization software used in backup power systems.
Since its first commercial product launch in 2022, the company has expanded its deployed infrastructure to more than 60 cities across India, serving customers across mobility, industrial, healthcare, hospitality, and residential segments. Reported deployments include organizations such as Mahindra, Maruti Suzuki, Clove Dental, and Atria Power. The company introduced its digital-twin monitoring platform and battery-identity framework in 2023, followed by a commercial and industrial energy storage product in 2024, and a residential storage product with virtual power plant participation capability in 2026.
TEC has raised institutional funding across a pre-seed and pre-Series A round, with pre-Series A investors including Siana Capital, Callapina Capital, Z21 Ventures, 1Crowd, and LetsVenture.
SDG 7 is directly relevant because TEC’s storage systems are designed to capture curtailed solar generation and reduce reliance on diesel backup power, supporting more reliable access to clean electricity. SDG 9 applies because the company builds physical and digital infrastructure, including battery hardware, IoT-based monitoring, and grid-services software, addressing gaps in India’s distributed energy market. SDG 12 is supported through the company’s emphasis on extending battery lifespan, enabling predictive maintenance, and pursuing second-life battery use, which reduces premature replacement and material waste. SDG 13 is relevant because the company’s core value proposition, reducing diesel generator use and improving utilization of renewable generation, directly targets emissions associated with backup power and curtailed clean energy.
TEC operates as a hardware-and-software energy storage company, engineering lithium-ion battery packs and stationary storage units alongside a cloud-connected monitoring platform. Each deployed unit, whether a mobility battery pack or a stationary storage system, is assigned what the company calls a Battery Aadhaar, a persistent digital identity intended to track manufacturing origin, usage history, and degradation data across the asset’s lifecycle. This data feeds into FlexiTwin, an AI-based digital-twin platform that continuously ingests telemetry such as state of charge, temperature, cycle count, and load pattern to model battery condition, flag anomalies, and schedule predictive maintenance.
For commercial and industrial customers, the company’s approach centers on replacing diesel generator backup with battery energy storage systems that switch automatically between grid and stored power and prioritize critical electrical loads during outages. For assets already deployed, the company aggregates FlexiPack and FlexiPod units into a coordinated network intended to participate in grid services such as demand response and peak-tariff arbitrage, a model commonly described in the industry as a virtual power plant.
On the mobility side, the company has pursued third-party performance validation, including a certified range rating from India’s Automotive Research Association for one of its battery packs, and has worked with EV charging-network operators to help ensure charger compatibility across its product line.
TEC operates in India’s distributed energy storage and battery-intelligence segment, positioned between component-level battery manufacturers and larger grid-scale storage integrators. Its customer base spans electric-vehicle fleet operators, commercial and industrial facilities seeking diesel-generator alternatives, solar and wind developers facing curtailment, and residential customers in areas with unreliable grid supply. The company differentiates its offering by pairing battery hardware with a proprietary digital-identity and monitoring layer intended to provide lifecycle visibility and enable virtual power plant participation, rather than selling batteries as a standalone commodity. It has secured deployments with automotive and industrial customers including Mahindra, Maruti Suzuki, and Atria Power, alongside early-stage venture funding from a group of India-focused investors.
TEC addresses a genuine structural problem in India’s energy system, the mismatch between growing renewable generation and grid infrastructure that cannot always absorb or store it. By combining battery hardware with software for monitoring, load prioritization, and grid-services participation, the company is attempting to serve a market segment, distributed commercial and industrial storage, that sits between individual battery sales and utility-scale storage projects. Its stated deployments across automotive, healthcare, hospitality, and industrial customers suggest the model has found early commercial traction beyond a single vertical.
As an early-stage company operating in a capital-intensive hardware category, TEC’s claims around uptime, payback periods, and performance guarantees are drawn primarily from its own marketing and customer testimonials rather than independently audited data, and its disclosed funding to date, in the low single-digit millions of dollars, is modest relative to the scale of infrastructure described on its website. The company’s approach of pairing a proprietary battery-identity framework with an AI monitoring layer is a reasonable response to a well-documented industry problem, battery lifecycle opacity, though its long-term differentiation will depend on execution and third-party validation as it scales.
