Changing Pattern Of Energy Demand inGlasgow

Background: UK Low Carbon Agenda

• There is a Cunning Plan.......
Background: Translation to UK Energy Picture

• Thank You National Grid For Scenario Analysis: http://www.nationalgrid.com/uk/Gas/OperationalInfo/TBE/Future+Energy+Scenarios/
• 3 scenario picture with built in Economic Growth Predictions, Axioms and Heroic Assumptions!
• This is only one well laid out and coherent future energy picture created by National Grid (The Major Gas and Electric company in the UK).....
• The Devil is in the detail!
Background: The City Energy Mix Implications

Heat • Domestic Heating transfer to Electrical Power• Industrial Heat use of Bio-fuels/Mass & Carbon
Capture• Burning Fossil Fuels kept for ‘High Grade Heat’
Transport• Cars (and Buses?) all Electric or Hybrid• Electric Mass transit systems • Burning Fossil Fuels kept for Aviation & Shipping
Background: The future is Electric!
5
• Things Don't Take off till Electricity is Cleaned up in the mid 20’s!
• Reduction In Electrical Demand till Then
• Concurrent Reduction In Gas Demand
Glasgow Energy Changes: Energy Efficiency
6
• Minimise Energy Requirement!
Devices• Background improvement in Energy
Efficiency• Boilers• Appliances
Buildings• New Development: Managed by
Building Regulations• Retrofit: Massive Encouragement In
Building Improvement• Green Deal• ECO• Carbon Reduction Commitment scheme for
large Commercial & Industrial Users• Building Energy Certificates

A Key area for Debate & Decision!Community Energy Systems V Continued Individual Building Installation
Individual Building Installation• Domestic Heat Pumps• Single Commercial Building Level Electrical
Heat/Cooling Pump System’s • Biomass/Bio fuel Installations
Energy Mix Implications• Increased Electrical requirement• Smart Grids and Reinforcement of electrical system
Community Energy Systems• CHP & District Heating networks• Feeds Electrical Energy in & provides Heat• Taps into Waste/Process Heat and Geothermal Heat• Flexible Technology for Energy Centre• Adapt as Low Carbon Requirement Grows
Energy Mix Implications• New Energy Infrastructure: Heat Network• Minimise Requirement for Electrical Reinforcement
Both Valid Solution’s For Low Carbon RequirementCreate a Environment for Mixed Solution Driven by Heat and Building Density?

Glasgow Energy Changes: Transport
Increased Requirement for Electrical Energy for Transport needs
• Individual Car Use• Buses• Mass Transit Systems
• But....lots of Smart Grid Potential (Smoothing out the Demand Profile)• Overnight Charging• Time of Use Tariffs• Predictable Car Usage : Use of Car
Batteries for Energy Balancing Storage devices etc...

Glasgow Energy Changes:Low Carbon Technology Penetration
Micro generation• Driven By FITS• PV prevalent in Cities
Community Scale generation• CHP: Dependant on Community Heating schemes
penetration, • CHP: LCT Energy Technology Independent• Others at Low Level: Urban Wind
Micro Renewable Heat • Driven by RHI • Heat Pumps, Air & Ground Sourced• Biomass
Community Scale Renewable Heat • Waste & Process Heat• Geothermal• Large Scale Biomass• Bio-fuels & Anaerobic Digestion

Glasgow Energy Changes: Summary
Now to 2030• Little Change in Current Energy Mix• Decrease in Energy Use Due to increasing Energy
Efficiencies (balanced by Increasing Population/GDP)
• Drive for Building Improvement, LCT Penetration and Background Clean Up of Electricity
DECC: Updated Energy & Emissions Projections 2012
2030 to 2050• Move away from Hydrocarbon Sources (Gas and
Petrol) to Electrical Energy• Drive for Electric Transport and Electrical
Heating Systems (Heat Pumps)• Continued Drive for LCT Systems to support local
energy Infrastructure• Need for Smart Grids to maximise LCT potential
and minimise new Infrastructure
Decisions By the City To Influence Final Energy Mix Picture
• How to Maximise Energy Efficiency Potential
• Encouragement of Citizens LCT take Up• Mass Transit Transport Decisions • Strategic Decisions on Supply of Heat
