1 Solar Rooftop PV Municipal regulation, application, approval etc. processes

2 Hardcopies participants will need: Full AMEU resource pack Process flow diagram Application process checklist Filled in application form examples (for Workshop sessions) Bylaw detail document

3 AMEU SSEG Resource Pack 1. Requirements for Embedded Generation 2. SSEG Supply Contract 3. SSEG Application Form 4. SSEG Commissioning Form 5. SSEG Decommissioning Form Forthcoming: 1. Process flow 2. Checklist 3. By-law amendments

4 The aim of compiling standard documents Learn from experiences from the metros and share with local municipalities, so as to avoid that each municipality re-invent the wheel Ensure sound processes and safety in all municipalities Facilitate processes for installers (similar approach in all municipalities although differences might still exist)

5 The rational / methodology Different municipalities have used very different approaches in terms of detail required in the applications, and thus complexity of Application Forms varies greatly. The drafts have erred on the side of being reasonably detailed, although not quite as demanding as some of the metros Forms currently. The logic was rather to put in too much than too little, as its easy to delete sections seen as unnecessary. Many would however welcome more simplicity. This might be made easier when all standards are finalised

8 AMEU Standard Document SSEG Application Form Still quite long and complex (4 pages + 2 for office use) Municipalities can delete the information they would not use Structure of the form: A. Applicant Property and installers information B. Embedded generator technical information C. Regulatory requirements and standards D. Declaration Attachments For office use

9 AMEU Standard Document SSEG Commissioning Report

10 Optional commissioning tests OPTIONAL TECHNICAL TEST SHEET for the small scale embedded generation installations Disclaimer: From a technical point of view the NRS test certificate covers these issues quite thoroughly, so there are no safety concerns that REQUIRE the municipalities to do such tests as described below. Municipalities may perform such tests on selected (few) installations for additional comfort on safety aspects. Project name: Commissioning Test: 1. Anti-islanding test: (multi-meter required) With the system running (main breaker closed and SSEG producing power), OPEN the main breaker to the SSEG installation. - Does the SSEG activate anti-islanding mode? Measure the voltage at the AC output terminals of the SSEG or at the connection point to the AC mains board. 2. SSEG Re-connection test 1: (stop watch required) With the main breaker OPEN and the SSEG in island mode, reconnect the mains (close main breaker). Measure the time the SSEG takes to reconnect to the network/grid. 3. SSEG Re-connection test 2: (stop watch required) Take note of the reconnection time in test 2. With the main breaker OPEN and the SSEG OFF, CLOSE the main breaker. In 10 seconds or before the SSEG can reconnect to the grid, open the main breaker. Does the SSEG activate anti-islanding and disconnect from the grid? 4. Inspection of labels: Client side: Check that there are labels on the distribution board clearly indicating the SSEG infeed and point of connection(s). Check that there are labels on the outside of the distribution board Network/Grid Side: Check that there are labels on the feeder and substation, clearly indicating that there is SSEG present on this installation. Comments/Results YES/NO...V.s YES/NO

11 AMEU Standard Document SSEG Contract Supplemental agreement; 9 pages Based on the equivalent contract from CCT and GreenCape generic contract for Western Cape municipalities and draws on elements of contracts from other municipalities Does it need legal review (by some legal departments in metros if possible)?

12 AMEU Standard Document SSEG Decommissioning Report Requires a COC to certify decommissioning

13 Requirements doc: detail

14 Application & approval process - 1. Application overview process to install SSEG PROCESS FOR THE CUSTOMER INTERNAL TO MUNICIPALITY

15 Internal process (detail)

16 Example of process

17 Process with PV GreenCard (future) CURRENTLY: GreenCard registration number of installer gives comfort to municipality regarding technical competence of installer. FUTURE: GreenCard and Municipal Application forms are aligned CURRENTLY: GreenCard registration provides assurance of NRS compliance, simplifying application assessment requirements of the municipality. CURRENTLY: GreenCard certification may give munics comfort in commissioning so they only inspect large systems FUTURE: GreenCard is able to give strong enough assurances to munics around commissioning and installer accountability so they need to inspect only unusually large systems 17

23 Workshop Work through a pre-completed application As a group Small groups (different application forms)

24 By-law amendments for SSEG General areas to be addressed Specific sections

25 Areas where the Electricity Supply By- Law needs to address SSEG concerns: Require all prospective SSEG generators to obtain the written agreement of munic to connect Require that the application process be adhered to, and conditions in the Requirements for embedded generators document by complied with. Require that safety and power quality issues be explicitly addressed and are the customers responsibility. This includes inverter safety and compliance certification. Obtain consent that the SSEG installation may be accessed by munic staff as required. Assert that munic has the right to disconnect non-compliant SSEG systems. Assert that munic has the right to set norms and standards and change these from time to time. Assert that munic has the right to set SSEG tariffs and billing arrangements, and change these from time to time.

26 By-law details

27 Capturing SSEG info in municipal software (e.g. Smallworld & SAP) Questions to clarify an approach: What info does NERSA need? What info does the munic need for customer/billing purposes? What info does the munic need (beyond application evaluation) for technical purposes? PV GreenCard information collection streamlining?

28 SmallWorld/GIS can record lots of technical detail

29 SAP can be used to track applications (limited technical aspects)

30 Software integration SAP less technical, more business & customer focused SmallWorld high technical functionality Integration

31 Functions to be performed by software systems Function Notes/detail System Record basic data System type, max AC output, DC kwp, storage, contract signed date, reverse feed blocking, other relevant, NERSA license required Record tariff customer is on Enable extraction of data required by NERSA Track status of SSEG application and approval (can be used instead of hardcopy Control Document) Track identified illegal SSEG connection status Storage for relevant documentation Enable queries on existing SSEG capacity on various feeders (test for NRS compliance) SSEG tariff applied, date, handling of negative consumption (i.e. net export) (see list lower down) Application received, stage of assessment, meter installation, commissioning inspection, approval letter issued, date approved, decommissioning status ALSO: grid impact study and status (if relevant) Illegal system and disconnection warning issued, disconnection/reconnection status Application form, Contract, Inverter test certificate, commissioning form, approval letter System max AC capacity, storage, type of system, 1ph / 3ph, feeder information, substation information Customer management/billing software (e.g. SAP) Customer management/billing software Customer management software OR GIS system Customer management software Customer management software Customer management software GIS software for utility distribution networks (e.g. SmallWorld) Enable identification of SSEG for Location, reverse feed blocking, technicians working GIZ on - feeders All rights reserved max AC capacity GIS software for utility distribution 31

32 NERSA info needs (proposed) From a NERSA perspective, the following needs to be asked for in the SSEG application process: 1. ID of installation 2. Generator technology (PV/wind/biogas/diesel/fuel cell/generation) 3. Type of installation (rooftop/ground-mounted/building integrated) 4. Newly built capacity or capacity extension of an existing system. 5. License exemption classification (according to DoE License Exemption Notice). 6. Date of connection agreement 7. Date of registration of the installation 8. Date of commissioning of the installation 9. Date of decommissioning of the installation 10. Installed capacity: kw at grid connection point 11. Installed module capacity (PV only): kwp of installed modules 12. Location of SSEG system (street name, house number, city, zip code, GPS coordinates) 13. System includes storage (yes/no). Storage capacity in kwh (if yes). Storage for grid tied operation (yes/no). 14. and any other information, which is required by NERSA as detailed by the corresponding regulation.

33 Workshop: Municipal software SSEG info capture Develop a brief for software staff: Information needed (populate table, add items etc)

34 Illegal systems: Clear legal grounds for illegal system disconnection in bylaw: Have not adhered to application process Have not obtained written agreement from the municipality Safety and power quality issues have not been explicitly addressed But the municipality wants to: Help people become part of the system Not chase customers off-grid Engage with them in a supportive way (e.g. provide an encouraging notice of violation but also support in engaging with the application process with a deadline?) (still will be a problem, given the likelihood of illegal system inverters being non-compliant, so disconnection will remain a clear need often)
