As the New Year begins, looking back at the ground Promethean Power Systems has covered in 2016 can provide clear insight into how the company can use its innovative chilling technology to help dairy partners improve quality and save cost. The Powering Agriculture: An Energy Grand Challenge for Development (PAEGC) annual report for financial year 2016 gives Promethean Power Systems an opportunity to do precisely that.

The latest PAEGC annual report features Promethean Power Systems’ progress in helping its dairy partners switch over to a cleaner and more cost-effective way to chill milk. Promethean’s major collaborators on the project are Hatsun Agro, India’s largest private dairy company, and Orb Energy, a leading solar energy solutions provider in India.

The report assesses the commercial and social benefits of Promethean’s refrigeration solution covering specific aspects such as wider market linkage to farmers, higher income through improved milk quality, reduced milk spoilage, and elimination of diesel as a power backup source.

PAEGC is an initiative undertaken collectively by The United States Agency for International Development (USAID), the Government of Sweden (Sida), the Government of Germany (BMZ), Duke Energy Corporation, and the United States Overseas Private Investment Corporation (OPIC).

Since 2012, PAEGC has been supporting the development and deployment of clean energy innovations that increase agriculture productivity and stimulate low-carbon economic growth in the agriculture sector of developing countries to help end extreme poverty and extreme hunger.


Under Promethean’s Progress Update section, the Powering Agriculture annual report observes that:

“Promethean has now sold over 400 units, of which they have deployed and commissioned over 250 milk chillers coupled to its patented Thermal Battery. The remaining units are pending installation or are in production today. To date, none of the 250 Promethean chillers in the field have required a diesel generator. Without Promethean’s Thermal Battery, a traditional milk chiller would have run diesel generators to chill milk in these villages, leading to higher costs and increased carbon emissions, or milk chillers would not have been installed at all, leading to greater spoilage and decreased quality of milk. As deployment of the chillers continues, Promethean has been able to adapt the solar component design to address specific logistical needs of dairy partners.”
