What Promethean Power Systems does
Promethean Power Systems designs and manufactures rural refrigeration equipment for cold-chain applications in off-grid and weak-grid environments, primarily serving dairy processors, farmer collectives, and food producers in South Asia and East Africa. The company was founded in 2007 as an MIT spinout by Sorin Grama and Sam White, with US operations based in Somerville, MA (Greentown Labs) and manufacturing and operational headquarters in Pune, India (Promethean Spenta Technologies Pvt. Ltd.). Its core technology is a proprietary, patent-pending Thermal Storage System (TSS) — a phase-change-material thermal battery that stores up to 28 kWh of cold energy when grid power is available and releases it during outages, enabling diesel-free milk chilling and produce cooling. The hardware portfolio spans Bulk Milk Chillers (500–2,000 LPD), Micro Can Chillers, Mobile Milk Chillers, Cold Storage Solutions, and Reefer Trucks, with an optional Solar Add-On module. Software layers include ProAMCU for dairy procurement management, the ProConnect farmer-facing app, and IoT-based equipment monitoring offered on subscription.
The company operates two go-to-market models. The B2B arm sells or leases thermal-battery chilling equipment to large enterprise customers including Amul, Hatsun Agro, Heritage Foods, Lactalis/Thirumala, Mother Dairy, Nestlé, ITC, Fonterra (Sri Lanka), and BRAC/PRAN (Bangladesh), with cumulative installations of roughly 3,000 units across India, Bangladesh, Sri Lanka, Tanzania, and Mexico. Since 2018, customers can also lease equipment on a per-litre processed basis (~18 paisa per litre vs ~50 paisa for diesel-based chilling). The Farmer Platform arm deploys Rural Chilling Hubs operated by women-led FPOs in Maharashtra, aggregating and chilling milk from smallholder farmers for supply to processors while offering credit, inputs, and veterinary services through Lakshmi Centres. Revenue streams therefore include one-time equipment sales, recurring/usage-based leasing and IoT subscriptions, and transaction-based commission from the Farmer Platform. Key investors include Acumen ($1M, Oct 2019) and TotalEnergies Ventures (Jan 2020), with development funding historically from NSF, Lemelson Foundation, and USAID.

Revenue model
- Equipment Sales (B2B): Direct sale of milk chillers, bulk milk coolers, cold storage units, reefer trucks, and mobile milk chillers to dairy and food processing companies. One-time capital purchase with long-term operational benefits including elimination of diesel costs.
- Equipment Leasing / Pay-as-you-go: Subscription/pay-as-you-go model added in 2018. Customers lease equipment on per-litre processing basis rather than purchasing outright. Enables dairy companies to expand into remote villages without capital investment. Company charged commission for services provided through rural chilling hubs.
- Software Subscriptions: IoT monitoring systems offered on subscription basis. ProConnect farmer app provided as complementary application to ProAMCU.
- Milk Chilling Solutions (Farmer Platform): Platform model working with FPOs to collect, chill and supply milk to dairy customers. Payment for milk transferred to farmers; company charges dairies commission for services. Additional revenue from enabling credit, dairy inputs, and veterinary services through Lakshmi Centres.
