Stowell Dairies required capital investment to improve the dairy unit at East Stowell and to meet amended slurry regulations. EnviTec Biogas UK worked with them to design a biogas plant that would produce 4.1 million kWh of electricity and 3.55 million kWh of surplus heat. The facility is part of a new development of 500 dairy cows with state of the art milking and handling facilities. The project also incorporates a viewing gallery and education room overlooking the parlour, and new welfare facilities. In addition, finance went towards feed storage buildings and silage clamps, ensuring Stowell is self-sufficient in feedstock. Return on investment is expected within seven years, and as a result of the additional income and the wider capital investment, the existing workforce has been preserved and additional jobs created.
