Heat Pumps & Solar Power Deliver On-Farm Efficiency and Sustainability ESP Energy delivered a fully integrated renewable energy solution for a leading UK dairy farm, combining 4 x 100kW heat pumps and an 80kW solar PV system to create a highly efficient, low-carbon milk cooling and site heating system. The innovative setup cools milk instantly to below 4°C, while recovering the extracted heat to supply process water, space heating for on-site properties, and calf welfare facilities. As part of this forward-thinking installation, ESP Energy also designed and manufactured a custom 35,000-litre bulk milk silo. The insulated tank uses advanced cooling plates on the sides and base to maintain optimal storage temperature, reducing energy demand, increasing hygiene, and protecting product quality.
