Milma, the cooperative dairy facility administered by the Kerala state government has installed a 2 MW captive solar installation at Ernakulum. The new installation has managed to decrease monthly electricity expenditures from Rs 4 million to Rs 1.5 million. The National Dairy Development Board has provided a long-term credit of Rs 115 million at discounted interest rates to fund the solar facility. To mitigate carbon emissions and make the facilities more cost-effective, 14 similar dairy factories in Kerala will shortly join the initiative. Kerala Co-operative Milk Marketing Federation intends to deploy solar energy to power all its factories and milk processing units.
The dairies are located across Ernakulam, Thiruvananthapuram, Alappuzha, Kattapana, Kottayam, Pathanamthitta, Kannur, Thrissur, Kollam, Kozhikode, Malayora, Palakkad, Wayanad, and Kasargod. The milk is sourced through a network of over 3,000 primary co-operatives and around a million dairy farmers. These cooperatives have annual revenue of more than Rs 30 billion.
Recently in July 2022, Kerala State Electricity State Electricity Regulatory Commission granted approval to the Kerala State Electricity Board to buy 90 MW of solar electricity from NTPC for a period of 25 years at a discounted price of Rs 2.77/kWh.
