Energy case study: Terra Spirits & Liqueurs

Terra Spirits & Liqueurs is Ireland’s largest family owned Irish Cream Liqueurs producer. Through a series of energy efficiency installations and improvements over two years they have been able to save €15,000 on heating bills alone and have reduced their total energy demand by 25%. 

Efficiencies introduced

Measures taken include converting from oil to bioLPG gas which has saved 132,000kg of carbon dioxide emissions and reduced Nox levels by 80%. They have also installed a solar PV farm with a capacity of 340 Kwh equivalent to 1,100 panels. This now produces 50% of their total electricity demand (240,000 Kwh). An air to water heat pump system now provides hot water and an overall reduction in oil use of 30% – equivalent to 26,000 bulk litres. Other changes include an automated waste water recovery system which saves 0.5m litres of water annually, as well as a heat recovery water tank. Previous steps the company had taken towards energy efficiency also included insulation retrofitting and conversion to LED lighting.

Future plans

In the long term the company hopes to save 80,000kg of C02 annually through the solar PV farm. The heat pump and water recovery system have greatly reduced their waste and will have a 10-year payback period. For their efforts Terra Liqueurs won the SME category for Exemplary Energy Management  at the SEAI 2020 Energy Awards.
