  16. Energy Efficiency & Demand Side Management www.kznenergy.org.za info@kznenergy.org.za

  17. Energy Efficiency & Demand Side Management www.kznenergy.org.za info@kznenergy.org.za

  18. Energy Efficiency & Demand Side Management Average daily Load Curve www.kznenergy.org.za info@kznenergy.org.za

  19. Energy Efficiency & Demand Side Management Peak Demand Highest in Winter www.kznenergy.org.za info@kznenergy.org.za

  20. Energy Efficiency & Demand Side Management Cost of meeting Peak Demand with Gas www.kznenergy.org.za info@kznenergy.org.za

  21. Energy Efficiency & Demand Side Management • Energy efficient appliances • System Optimisation • Smart metering • Behaviour change • Examples • UKZN energy saving HVAC pilot (commercial energy efficiency) • Cato Manor Green Street Project (residential energy efficiency) www.kznenergy.org.za info@kznenergy.org.za

  22. UKZN energy saving HVAC pilot Source: Gregory Diana, Head of the Energy Management Programme at UKZN • ~60-65% is Heating Ventilation and Air Conditioning (HVAC) • 10-15% hot water • 30-20% lighting and general office usage • With HVAC at ~60-65% of total consumption, the largest energy and financial savings may be made via load shifting and thermal storage in combination with the ToU tariffs. • General office space and lighting cannot be load shifted (cheaply). • Hence they offer best combined energy and financial savings or best ROI. www.kznenergy.org.za info@kznenergy.org.za

  23. UKZN energy saving HVAC pilot • Daily consumption remains constant • Load curve flattens • Rand savings from displacing demand during peak to off-peak when Time of Use (ToU) tariffs apply

  24. UKZN energy saving HVAC pilot • Potential for more thermal storage at UKZN: • Howard College Campus has ~ 50% thermal storage for all its HVAC at the moment. • Westville (~2.5 MW), • Medical School (300 kW), • Edgewood (~100 kW) and • Pmb( 1 MW) www.kznenergy.org.za info@kznenergy.org.za

  25. UKZN energy saving HVAC pilot Environmental Impact of Installing Efficient Showerheads: Source: Gregory Diana, Head of the Energy Management Programme at UKZN

  26. UKZN energy saving HVAC pilot off-peak thermal storage system for hot water at residences • non-pressure system and only uses electricity to make hot water when electricity is cheapest. • Low pressure system reduce risk and allow for much cheaper tank ~ 50% saving over conventional geyser. • Short pay-back period www.kznenergy.org.za info@kznenergy.org.za

  28. Cato Manor Green Street Project Improving Lives by Greening Low Cost Housing • Initiative of Green Building Council of South Africa • Funded by British High Commission & Phase 2 by Australian Gov’t Source: Nick Alcock, Khanyisa Projects download original presentation

  29. Cato Manor Green Street Project Low Pressure Solar Water Heaters (SWH) • SABS approved • 85% local components

  30. Cato Manor Green Street Project Installation of light weight ceiling • Thermal Resistance Value (R Value) of 1 • 4 – 6 degrees cooler during hottest time of day www.kznenergy.org.za info@kznenergy.org.za

  31. Cato Manor Green Street Project Heat Insulation cookers • If used 3 times a day can reduce 0,5 tonnes CO2 per year

  32. Cato Manor Green Street Project Safe Electrical Wiring • Safe wiring reduces risk of fires and shocks • Better security through improved lighting

  33. Cato Manor Green Street Project LED Street Lights Also…Rain water harvesting, food gardens & fruit trees

  34. Renewable Energy & Electricity Generation in KZN

  35. Renewable Energy & Elec Generation Electricity Industry overview • Electricity price rising rapidly • Electricity demand rising • REIPP Procurement Programme by DoE 3,725MW allocated to RE • 3,625 MW Large Scale (over 5MW) • 100 MW Small Scale (1MW – 5MW) • Embedded generation (10kW – 1MW) • Co-generation

  36. RE IPP Procurement Programme REIPPP projects awarded by province in REIPPP Round 1 www.kznenergy.org.za info@kznenergy.org.za

  37. RE IPP Procurement Programme www.kznenergy.org.za info@kznenergy.org.za

  39. RE IPP Procurement Programme Review of Successful bids Round 1 and 2 www.kznenergy.org.za info@kznenergy.org.za

  40. Renewable Energy & Elec Generation Examples • Soitec Concentrated Solar Photovoltaic (electricity generation) • Dube Trade Port Agrizone (embedded generation) • NCP Alcohols (cogeneration) • also UmzimkuluIlovoSugar Mill, AmatikuluTongaatHulett Sugar Mill

  41. Renewable Energy & Elec Generation Soitec Solar CPV Plant • 477 KWp Concentrated Solar Photovoltaic Plant • Near Hazelmere Dam • Sells electricity to eThekwini

  42. Renewable Energy & Elec Generation Soitec Solar CPV Plant • Dual-axis tracker systems enable the CPV unites to follow the course of the sun in its azimuth (east to west) and its elevation (height above horizon). Watch the video on our website here

  43. Renewable Energy & Elec Generation Soitec Solar CPV Plant • Concentrate sunlight onto a very small surface by a factor of 500 • Small surface area reduces amount of costly cell material required.

  44. Electricity Generation from IPPs RE Power station  Electricity Grid  electricity meter  end use www.kznenergy.org.za info@kznenergy.org.za

  45. Renewable Energy & Cogeneration NCP Alcohols 3MW Cogeneration • Uses by-product of its production process, steam, to generate electricity. • Piped gas-fired high pressure boilers drive a 3MW steam turbine for 350 days of the year to not only provide all the plant electricity requirements, but also low pressure steam from the turbine exhaust.

  46. Cogeneration Electricity Grid  electricity meter  cogeneration  production / end use www.kznenergy.org.za info@kznenergy.org.za

  47. Renewable Energy & Elec Generation Dube Trade Port Agrizone • Solar PV 700 KWp • Generation for own-use • Grid tie

  48. Renewable Energy & Elec Generation Dube Trade Port Agrizone • Even with additional capacity, very little power is being exported • designed to generate enough power to supplement the electricity requirements for the packhouse and greenhouse C, estimated at 3800-4000 kWh/day over a 24hour period.

  49. Renewable Energy & Elec Generation Embedded / Decentralised Generation • The KSEF Guide to Application Procedures for Embedded Power Generators in KZN • industry standards, • Grid tie approval, • licenses and contracts from the relevant electricity distributor. • KZN Munics that have already accepted grid-tie: • eThekwini • Newcastle • uMhlatuze (Richards Bay) www.kznenergy.org.za info@kznenergy.org.za

  50. Renewable Energy & Elec Generation • KZN Solar PV roof top availability database • KZN RFI Solar PV • eThekwini buys electricity from local generators • Payment is based on the avoided cost principle. This means that eThekwini is able to pay generators for electricity at the same price it would have cost to purchase electricity from Eskom. Eskom sells electricity to municipalities at the Megaflex rate, which is based on a time of use tariff, hence eThekwini applies the Industrial Time of Use tariff to embedded generators. www.kznenergy.org.za info@kznenergy.org.za
