Changing Pattern Of Energy Demand inGlasgowJim Whyte16th July 2013


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!

  • 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

  • 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


Glasgow Energy Changes: Heat

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 Requirement

Create 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

  • 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

DECC: Updated Energy & Emissions Projections 2012

  • 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
