8 Our Vision To be recognised as the partner for leading sustainable energy solutions Delivering An Award Winning World Leading Renewable Energy Solution At Old Oak Common Crossrail Depot In Partnership with Friday, 21 October 2016 GI Energy 8

9 Old Oak Common Bombardier s contract with TfL requires 32-years of depot management and fleet maintenance of 33no. 250m long trains compliance with TfL s strict environmental requirements delivering lowest possible running costs through energy-efficiency. CO2 reduced by >20% >20% of energy from renewables Railway Sidings Friday, 21 October 2016 GI Energy 9

10 Solution chosen GI Energy s Role 10

11 GI Renewable Energy Solution - Crossrail Old Oak Common Depot GSHP System will provide 1000kWth heating and 600kWth cooling using 52no 150m deep boreholes 466no 15m deep energy piles under the building CHP System will provide 420kWth heating and 290kWe of electrical load 200m² Solar Thermal will add a further 140kWth of hot water load 1500m² Solar PV will provide a further 220kWe Friday, 21 October 2016 GI Energy 11

12 Illustrations Geothermal piles and boreholes 466no Energy piles and 52 no boreholes will deliver 1000kWth heating and 600kWth cooling 12

13 Solar PV and Thermal 1500m² Solar PV Contribution 281,270kWe 5% of Total Depot electrical requirement 200m² Solar Thermal Contribution 78,853kWth 40% of Total depot hot water requirement Friday, 21 October 2016 GI Energy 13

14 PV Opportunity Roof mounted PV Using electricity generated on site is better than importing it. Self Generation tariff = 2.03p/kWh Import tariff = 9.5 to 14p/kWh A GSHP with a COP of 4 running on electricity generates heat at 2.4p/kWh. A GSHP running on PV electricity at is effectively free heat At OOC this means a further saving of 281,270kWe/ annum x 2.4p = 6,750/ annum or 216,000 over the life time of the project Friday, 21 October 2016 GI Energy 14

15 Solar Thermal The size of thermal array limited by maximum energy used on hottest day of the year. 100% load only a few days of the year. By capturing and storing the peak energy, we deliver a greater daily and annual load to satisfy more demand. Also by storing a lower grade heat in the ground we can capture 5 times more energy from the sun than would ordinarily be used for DHW or heating only. Friday, 21 October 2016 GI Energy 15

16 CHP Requirements Deliverables Supply install test and commission a CHP System will provide 420kWth heating (54% of building requirement) 290kWe of electrical load (15% of building requirement) Heat recovery loop connected to CHP will ensure that the ground loop is able to meet the peak heating load required throughout the heating season.

17 CHP Principle Pollution Conventional Power Generation 67% Waste Fuel Heat 100% Power Plant 33% Electricity Cogeneration = efficiency Pollution 20% Waste Heat & Mechanical Losses Electricity Fuel 100% CHP Plants 80% Steam Chilled Water 17

18 The CHP Equation The effective heat to power ratio of a gas engine is 1.2:1, so for 120kW of heat, it generates 100kW of electricity Best design practice should be led by heat load. 90% efficiency is only achieved if both electricity and heat demands are 100% simultaneous. Acceptable payback is based on a minimum 5000 hours run per annum. Friday, 21 October 2016 GI Energy 18

26 GI Renewable Energy Solution Highlights - Old Oak Common Depot Through our controls & long term management we will be looking to outperform on current assessed performance.. Based Upon Electrical, Heating and cooling profiles provided by Atkins 54% Heating and cooling will be provided from renewable technology 20% of electrical load generated on site from CHP / Solar PV 33% Renewable energy solution Providing Demonstrated Savings Of... Run cost savings 97,000 per annum when compared against conventional equipment Renewable Heat Incentive 193,628/ annum 530Tonnes of CO2 per annum Potential payback on investment < 10 Years Ultimately GI Energy s Solution will reduce the clients projected energy costs over the 32 year contract term by approx. 10.5M (a projected 1500% ROI on 700k capex increase and a 450% ROI on the total renewable energies package) Friday, 21 October 2016 GI Energy 26

27 So Why did the OOC project deserve to win the H&V Award GI Energy have delivered an exemplar project for Bombardier demonstrating The benefits of integrating renewable/ LZC solutions How a project of this scale can deliver a 33% renewable energy solution Energy cost reduction of 10.5M & CO2 savings of 17,000T over the 32 year life of the building The Judges said The award recognises that GI Energy have broken through the boundaries and set a new benchmark for others to follow in delivering renewable energy projects Friday, 21 October 2016 GI Energy 27
