From individual farmers to billion-dollar food and dairy conglomerates, Promethean Power Systems’ thermal-energy-based technology makes a measurable difference wherever preserving perishables is necessary. It’s what we do best.

Since 2013, leading dairies have installed Promethean’s systems across hundreds of village-level collection centers. We have helped our customers to chill milk successfully, without using a single drop of diesel through our Rapid and Conventional Chilling solutions running successfully across India, Bangladesh, and Sri Lanka.

The impact of our products also percolates to individual farmers, increasing their economic opportunity.

Our Impact on SGDs

Our farmers can double their net income from dairy within 12 months.


This is achieved by a combination of loans to increase cattle, dairy inputs to improve nutrition, and veterinary services to improve the health of their cattle. The farmer can avail of all of the services we provide on a cashless basis using milk as a currency so that they do not have to put any cash into the business.

We make the household open a bank account in the name of the woman and pay only into this account.

This creates a credit history for the women with the bank and enables them to access more financial services in the future. Studies show that paying into the bank account of the women also increases the savings of the household. Since most of the work with the dairy animals on their farm is done by the women they feel adequately compensated and are motivated to work towards further growing the business.

Women run the ‘Lakshmi Centres’ in the village.

We develop women ‘Village Level Entrepreneurs’ who get an additional source of income.

The Farmer Producer Organizations (FPOs) are our partners and we work with them on capacity building, income growth, and reaching sustainability in operations.

We lower the carbon footprint across the value chain from the farm to the aggregation centres through our technology, operations, and inputs to farmers and have a positive impact on the environment.

In the B2B equipment sales and lease business, we have installed 500 milk chillers over the last 2 years. These milk chillers are sold to large and medium scale dairies across India who install and operate them in villages as a part of their growth and expansion. Our chilling technology, which eliminates diesel, lowers the chilling cost for our customers and enables them to work in remote villages with unreliable grid supply. This brings market access for the farmers in these villages. On average 50 farmers pour milk into every milk chiller and we have impacted nearly 10000 end-user farmers indirectly through our sales and leasing business.

In our Milk Chilling Solutions business, we have installed 120 Rural Chilling Hubs over the last 2 years. Each hub caters to 25 farmers which means we impact around 3000 end-user farmers. In this business, our impact is direct as we work with the farmers to improve their incomes through increased productivity, better nutrition, and health for their milch cattle, and growing their herd through loans. In addition, we have developed 120 village-level entrepreneurs to run these centers who receive a steady income through us.
