Supply of Woodchip Biomass Fuel for Eden Campus Energy Centre

The supply of Woodchip Biomass Fuel for Eden Campus Energy Centre in Guardbridge. Eden Estuary Energy Limited (EEEL) owns the Eden Campus Energy Centre and District Heat Network. This is operated on a day-to-day basis by the University of St Andrews. This heat network provides heating and hot water to 44 buildings within the University’s teaching and student residence buildings within St Andrews town. The heat source for this district heat network is provided by a 6.5MW Biomass Energy Centre which is located within the University’s Eden Campus at Guardbridge. The Energy Centre Biomass Furnace is fueled by virgin coniferous soft wood woodchip in the form of a P45s graded biomass woodchip. The woodchip delivery system requires deliveries to be deposited using a ‘walking floor’ HGV trailer. The normal delivery load is c.25 tonnes. The woodchip is deposited via the walking floor trailer into one of two woodchip storage silos which will have been pre-prepared to accept deliveries by the University’s Biomass Operations Team. In previous years, the Energy Centre biomass furnace has burnt approximately 10,000 tonnes of virgin softwood woodchip per annum to meet the University’s heat demand. Annual woodchip usage is however weather dependent, and weather extremes can affect this usage by approximately ±10%. The Biomass Plant’s operational heat output plan is dictated by the seasons, with a much higher heat output required during winter months. Full details are included in the Specification, Fuel Supply Agreement and other documents that form part of the tender. Additional information: Although EEEL is the Buyer, this procurement is being administered by the University of St Andrews (UoSA).
