Connect your own generator to the electricity network |
New energy technology solutions in South Africa provide customers the
opportunity to redefine their role in the electricity value chain. These
solutions includes the installation of small generators to generate their own
electricity.
Investing in a generator involves a significant financial commitment and
therefore requires careful consideration of the following key aspects:
 |
Assessing the feasibility of your application
|
Step 1: High-level overview of the process
Your
responsibilities:
· Provide all the required personal documentation for the application
submission
· Identify your preferred generator network configurations
· All grid-tied generator options will require that your meter be upgraded (either completely changed out
or reprogramm
· Adhere to the legal and technical requirements (Step 2)
· Pay the application fee to Eskom
· Submit the applicable NERSA – (
National Electricity Regulator of South Africa), documents to Eskom in support
of the SSEG application
Eskom’s
responsibilities:
· Confirm that the customer is on a dedicated transformer. A customer
on a shared transformer will not be allowed to be grid tied currently. NOTE: It
is anticipated that these types of connections will be phased in and this
website will be updated accordingly.
· Categorize the voltage size of the connection (medium or low)
· Analyse the network requirements
· Provide a list of legal and technical documentation requirements to the
customer
· Invoice and confirm payment of the application fee before the
application is processed
· Provide a quotation for the Eskom work needed for the connection
· Once the generator has been registered on the NERSA database, Eskom
raises the charges as per the quotation and proceeds with completing the work
· Eskom will provide the customer with new supply agreements and a connection
agreement for the SSEG.
Step 2: Understand the legal and technical
requirements
Eskom technical requirements:
·
NRS 097-1:
Code of Practice for the interconnection of embedded generation to electricity
distribution networks: Part 1 MV and HV (Eskom 240-61268576 / DST 34-1765:
Standard for the interconnection of embedded generation)
·
NRS 097-2-1:
Grid Interconnection of Embedded Generation – Part 2 Small-scale embedded
generation – Section 1: Utility interface
·
NRS 097-2-3:
Grid Interconnection of Embedded Generation – Part 2 – Section 3:
Simplified utility connection criteria for low-voltage connected generators

Step 3:
Prepare to apply to Eskom for generator connection
Alternatively you can call 08600 37566 and ask
for a local advisor to contact you for help on the submission of your SSEG application
form.
Eskom needs to know the following:
·
Account
number.
·
Your name.
·
Geographic
area.
·
Contact
details.
·
Size of
embedded generator (kW).
·
Will the
power generated be used for Own Use on Single Account OR for reconciliation of
multiple Eskom accounts?
·
Phase and
circuit breaker rating (single and three phases).
·
Dedicated
transformer size.
·
Existing
supply notified maximum demand (kVA or Amp).
·
Maximum
export capacity in kW.
·
Generator
type: synchronous, asynchronous (induction) or inverter.
·
Energy
source: wind, photovoltaic (PV), landfill, biomass, biogas or hydro.
·
If
applicable, the photovoltaic (PV) system diagram will be used to confirm the
PV and invertor configuration.
Step 4:
Start the generator connection registration process
Register with
NERSA and obtain a license or registration letter from them (available online
from http://www.nersa.org.za/).
Step 5:
NERSA approved generator connection
Once NERSA has provided the
required license or registration for your SSEG application, if applicable, you inform and submit to Eskom. Eskom will raise the applicable fees as
per the quotation for the Eskom works required to connect the SSEG to the grid
 |
Project commencement and completion steps |
Step 1:
Sign the new supply agreement and provide technical generator design letter
You provide Eskom with a copy of the signed Embedded
Generation Installation report,
Step 2:
Start with installation and connection process
You start installing the generator portion of the connection works and
Eskom will also initiate any work to be done on its portion of the
connection works.
Step 3:
Quality assessments
Eskom conducts quality assessments throughout the
construction/installation of the electricity connection.
Step 4:
Inspection and approval
The installation needs to be tested and certified in accordance with the
national standards for such an installation.
Step 5: Create new customer account
The Eskom billing system is updated according to
the new supply agreement.
