3 Current Stakeholders in the Joint-Venture Project 1. icon Infrastructure LLP. 2. Combination of Rothes Distillers (CoRDe) - The Edrington Group / Highland Distillers - Thaibev / Inver House Distillers - Pernod Ricard / Chivas Brothers - Bacardi / John Dewar & Sons - Diageo / Diageo Distilling - Gruppo Campari / Glen Grant Dist. - Benriach Distillery Page 3

4 Process and Concept Page 4

5 Concept & Layout Main data for the CHP plant: - Fuel heat input: 34.1 MW - Power production (gross): 8.7 MW - Steam export (@ 4.5 bara): 7.5 MW Page 5

6 Main Suppliers & Key Dates. Main Suppliers Boiler and flue gas treatment: AET Fuel handling and storage: Various (designed by AET) Steam turbine and WCC: TGM Kanis / SPX Civil work: Robertson Northern Ltd. Evaporator (for syrup): Wellman Process Eng. Ltd. Key dates Planning permission January 2009 Financial close 22 nd April 2011 Environmental permit July 2012 Boiler erection started May 2012 Beginning of Turbine erection August 2012 Beginning of Commissioning (cold) August 2012 Synchronisation with electrical grid February 2013 Take-over 23 th June 2013 Page 6

7 Key Data about the Project Boiler capacity: 34 MW & 42.5 t/h of steam 84 bar & 452 C Biomass consumption (8300 h/y): 127,000 t wet draff/yr, i.e trucks/day 60,000 t wood chips/yr, i.e trucks/day Capacities of STG / WCC: 8.7 MWe / 23 MW Plant net efficiency: 48 % Budget: Approx. 60m Number of suppliers: > 160 / approx. 50 companies on site Duration of the project: 26 months Hours worked of site: h (30% boiler) Zero accidents. Safety induction: > 1000 people went through the safety induction Peak presence on site: 160 people Production team: (AET on-site O&M advisor for 2 years) Page 7

9 High Performance and Availability Performance test (12-13 June 2013): Specific wood chip consumption (measured as kg wood/kwh-net power): 100% wood chips: 91.6 % of guaranteed consumption 45% wood chips & 55% draff: 89.5 % of guaranteed consumption LESS FUEL / COST FOR SAME POWER PRODUCTION Net power production: 105.8% of guaranteed value MORE POWER FOR THE SAME FUEL HEAT INPUT Availability AET responsibility (measured DEC 2013 DEC 2014*): Net power production: 99.4 % Draff handling and firing system: 94.8 % *: Exclusive 14 days summer stop Page 9

10 AET Wood and Draff Dosing System Wood Dosing System Uniform fuel dosing No bridge building Rotary Valve Easy external adjustment Spreaders Easy external adjustment Draff Dosing System Mass flow dosing Uniform continuous dosing Draff Firing System Robust system (1-10 mm) FGR for NOx reduction Low emissions Page 10

11 AET Combustion System & Biomass Boiler Travelling grate Uniform air distribution Low maintenance costs Furnace Very limited refractory 850 o min. 2 sec. Overfire air system Staged air supply Heating surfaces Horizontal tubes low soot blowing consumpt. Superheaters & ECO No build up of slagging Low flue gas velocity Ash re-injection Dedicated for biomass Page 11

12 Aalborg Energie Technik a/s AET is an independent and leading provider of biomass fired energy systems. AET offer complete solution from design and supply to service, operation and retrofit for: Boiler plants Cogeneration plants Power plants within the range of MWt. Page 12

13 Rothes CoRDe Project Benefits 1. Socio-economic benefits: Replaced ageing fossil-fuelled drying plant. Retained existing jobs (upskilling) and created additional jobs (total 22). 2. Environmental benefits: The energy produced is CO2 neutral reducing emissions by 46,000 tonnes/year. Eliminated 18,000 tonnes/year of CO2 emissions from the old drying plant. Result: Net CO2 benefit 64,000 tonnes/year. Electricity equivalent to power 9,000 homes Converts distilling by-products into useful products at low environmental cost 3. Energy efficiency: Higher energy efficiency Supports sustainable policies for all stakeholders Control on costs Page 13

14 Rothes CoRDe Conclusion Plant net efficiency: 48 % Performance tests: 105.8% power production OR 90-92% fuel consumption (@ 100 % PP) Very reliable plant: 99.4 % av. with operating team of Low emissions : With slight use of SNCR due to draff Commercial operation: 23th June 2013: Take-over Successful partnerships with Rothes CoRDe & suppliers: gave project delivery on time Page 14
