With the expected Eskom increases over the next five years, retail petroleum service stations are facing reduced profitability and some even closure as profits are continually eroded by rising operating costs. Electricity is one of the costs that can be managed and self generated.

This conference aims to examine best practices in energy efficiency and unpack the options and complexities of generating electricity from renewable energy specifically for retail fuel sites.

  1. 1. Energy for LifeEnergy efficiency for service stationsMay 2013Sustainable Efficiency…….through Objective Design
  2. 2. Energy for LifeAgenda– Why the focus on energy efficiency?– International best practise– Methodology– Key elements of Energy Management– Energy Auditing– Energy efficiency interventions– Incentives, Financing & Funding
  3. 3. Energy for LifeWhy efficiency – Landlord / Tenant?– Oil company or Landlord– Building Value– Increased Rental potential– Enhanced rental model– Dealer (Tenant)– Energy risk – escalating electricity prices– Long-term Profitability and Sustainability– Financing of efficiency interventions
  4. 4. Energy for LifeWhy efficiency – SA back drop ?– Immediate considerations:– Escalating energy prices threatening sustainability– Building Management – improve efficiency  savemoney– 10400XA – a requirement for refurb or new build– Property Investment - Valuations – key for future– Generator efficiency – how often is it used?– Incentives– Eskom SOP– Green funding
  5. 5. Energy for LifeWhy efficiency – SA back drop ?– Up coming considerations– Carbon Tax 2015– R120 per Ton of CO2– Example: CO2 for a Small SS 21T @ cost R2520– Energy efficiency Tax Incentives– National Energy Act 2008 - 34– Income Tax Act 1962 - 12L– Proposed R0.45 c/kWh saved– Apply by 2015
  6. 6. Energy for LifeInternational Best Practise
  7. 7. Energy for LifeSustainable Design methodology- First Reduce Demand –change procedure / behaviourand pro-actively manageDemand- then look for Efficiency –implement relevant technologiese.g. Voltage Optimisation or PCPower Management- then look to Innovate –generate Power on site– Solar PV or Wind
  8. 8. Energy for LifeKey elements of Energy Management– Measurement and Management– Behavioural and Procedural change– Technology interventions
  9. 9. Energy for LifeMeasurement and Management“If you can’t measure it youcan’t manage it”. PeterDrucker
  10. 10. Energy for LifeMeasurement and Management– Key issues– What am I using currently?– Am I charged correctly?– Am I on the right tariff?– How effective is my savings plan?
  11. 11. Energy for LifeWhat am I using? - Benchmark analysis– Know yourbenchmark– When am Ipeaking (kVa)?– Revise withtargets– Control energyusage against thebenchmark
  12. 12. Energy for LifeAm I charged correctly? - Bill verification– What am Iconsuming?– kWh– kVA– What rate am Ibeing charged?– Am I beingbilledcorrectly?
  13. 13. Energy for LifeAm I on the right tariff? - Tariff Analysis– Measureusagepatterns– Evaluateavailabletariffs
  14. 14. Energy for LifeHow effective is my saving plan?– Key areas– Behaviour and procedure change? –measure the effectiveness of the changes.– Technology changes – measure thevendor solutions for promised savings,paybacks and ROI.
  15. 15. Energy for LifeCost to measure?– On line Metering and switching– Measure 24 & control 8 points– R4500 Capital outlay– R250 per month
  16. 16. Energy for LifeKey elements of Energy Management– Measurement and Management– Behavioural and Procedural change– Technology interventions
