What’s needed? 1. Interested, Enthusiastic People 2. Senior Management Support 3. Allocation of Resources (Money) PLUS … Some Measure of Luck / Timing!

George Sq 1. 6 MWe CHP Pollock Halls 526 k. We CHP King’s Bldgs 2. 7 MWe CHP … invested £ 12 million in Decentralised Energy / CHP 2002 -2005 Edinburgh: “University in the City”

Edinburgh’s 3 CHP Projects 1. Pollock Halls: 526 k. We engine serving student residences as lead boiler – 2003 2. The King’s Buildings: 2. 7 MWe engine displaced old steam system + 2 new 7. 5 MW LTHW boilers serving high base load – 2004 3. George Square: 1. 6 MWe engine again replaced steam system – plus 75 tonne Heat Store and 600 k. W Absorption Chiller to even out load – 2005

UK Energy Flows – 50% wasted
