1. EKURHULENI EE and RENEWABLE ENERGY PROJECTS

2. STATE OF EE AND RENEWABLE ENERGY PROJECTS IN THE CITY
The City accounts for 1% of the total energy consumed in the Metro.
In line with the city’s climate change strategy the following projects were implemented:
Council EE Projects
Council Renewable Energy projects

3. Energy efficiency Projects
The city implemented Energy efficiency projects in three major categories through DoE DORA funding
Traffic lights retrofit – from halogen to LED
Street light retrofit – from MV to HPS and to LED in the near future
Building lights retrofit – from old technology of T12 and T8 to T5 and LED

4. COUNCIL RENEWABLE ENERGY PROJECTS
Also in line with EMM's Energy and Climate Change Strategy, which identifies proactive promotion of green power as essential for creating a sustainable future for the municipality, the following RE projects were implemented:
Solar water heating in EMM’s properties
Solar home lighting solution to informal settlements
200kW Solar PV Plant
Landfill Gas to Energy project
3 x 250kWp Rooftop Solar Plants

5. SOLAR WATER HEATING
In 2009 Municipal owned residential buildings such as old age homes, hostels etc were retrofitted with solar water heaters.
Both High and Low pressure SWH were installed in these buildings.
Concerns
Immediate concern was the issue of maintenance to prolong the life of these SWH.

6. SOLAR HOME LIGHTING PROJECT
The solar home lighting solution was introduced to informal settlements around the city
The solar lighting units consist of four (4) 2Watt very bright LED lights, a battery control box and a 15W solar panel.
The units make provision for the charging of cellular phones as well.

7. Concerns were around the issue of theft of the solar panels
Continued……..
Risk
Concerns were around the issue of theft of the solar panels

8. 200kW Solar PV Plant
In 2012 a 200kW Solar PV Plant was commissioned at O. R. Tambo Centre, Leeupan in Benoni using internal funding.

9. Continued……
The plant powers the OR Tambo Narrative Centre and the excess power is fed to the grid
Risk
The immediate threat facing the Solar PV Plant is theft of the Solar Panels as it is a ground level installation

10. 1MW Landfill gas to Energy Project
In September 2014, a 1MW generator at the Simmer and Jack Landfill site in Germiston was commissioned.

11. Continued….
The generator uses the methane gas collected from the decaying waste and generates 1 MW of clean renewable power.
This power is then fed to the EMM grid.

12. ROOFTOP SOLAR PLANTS
EMM in partnership with SEA put together a specification for installation of 2 x 250kW rooftop solar PV plants in two of the council owned buildings
Bid still under evaluation
Installation should commence in the next financial year
Concerns
Theft of the solar panels
Normal teething problems as this will be our first rooftop project.

13. COMMERCIAL AND RESIDENTIAL EMBEDDED GENERATION
Commercial and Residential customers are currently installing Rooftop solar plants for own consumption
Those who want to connect to the grid are required to fill in an application form
Majority of them do not exceed their base-demand
No Net-metering at the moment and no compensation for any excess power exported on to the grid
EMM is currently working on a Embedded generation policy and tariff

14. City of Ekurhuleni
NO FEED IN TARIFF (EXPORT TARIFF) YET IN PLACE!!

15. Customer applies / enquiry in terms of change to alternative supply installation
“DRAFT”
The information package should include the do’s and don’ts of PV / Generator / other Alternative supply installation
Only registered electrical contractors should provide the full details of the electrical installation and complete Annexure 4 of EIR.
The design of the installation should be planned and designed by an electrical engineer as per competent person OHSA /an AIA/ or Registered Contractor.
Only registered electrical contractors with registered electricians should execute the electrical installation work and provide COC of the installation as per OHSA Applicable EIR regulations and also SANS part 1 and NRS 097. Signed off by Electrical Engineers as per size of installation

16. “DRAFT”
In terms of PV Also provide information what are the categories of the ERA (4 of 2006) and when the application will require NERSA regulation and or licence.
Provide guidance and application forms in terms of the different categories as defined by NERSA.
In terms of the recent developments in the PV industry, it will be advisable for PV installers to be certified in terms of the PV GreenCard aspects
Provide advice in terms of possible meter change with a change in tariff to Feed-in Tariffs and provide some sort of explanation
Provide advice in terms of possible infrastructure change.
Provide advice in terms of safety and labelling.
Provide advice in terms of Continuous installation changes, maintenance and safe working principles. When PV panels and batteries are to be replaced it need to be disposed of in terms of the EWaste classification.
