What is eThekwini’s SSEG feed-in tariff and network-access charge in 2026/27?
eThekwini’s residential net-billing export credit for FY2026/27 is 160.52 c/kWh excl. VAT (≈184.60 c incl.), with a basic/network-access charge of R76.83/kVA excl. (≈R88.35/kVA incl.) per month on inverter kVA per the NERSA RfD (REC 8 May 2026; from 1 July 2026). Oversizing the hybrid quietly raises the monthly floor even when you export little — self-use still beats export versus ~411 c incl. domestic import on the same RfD.
Updated 27 October 2026 · Illustrative ranges — not a formal quote, credit decision or legal advice.
Answer first: Model avoided import first, then subtract network-access on the inverter kVA you actually need. A hero-sized hybrid that exports leftovers at ~185 c while paying R/kVA every month is a Durban own-goal.
Primary numbers (NERSA RfD FY2026/27)
| Item | Excl. VAT | Incl. 15% VAT guide |
|---|---|---|
| Residential export / feed-in energy | 160.52 c/kWh | ≈184.60 c/kWh |
| Network access (basic) on inverter kVA | R76.83 /kVA·month | ≈R88.35 /kVA·month |
Domestic Scale import energy in the same RfD sits near 357.47 c excl. (≈411 c incl.). Credits reduce the account; they are not cash withdrawals. Confirm live on your statement — secondary brochures have shown small R76.38 vs R76.83 rounding noise; we publish the NERSA RfD figure.
Design rules for Durban homes
- Right-size inverter kVA to continuous needs + diversity, not brochure headroom.
- Shift laundry, dishwasher and EV into sun hours.
- Bi-directional meter at customer cost during application.
- Registered SSEG customers move onto the relevant net-billing tariff.
Related: demand charges · self-use · City Power · Tshwane · metro hub.
Worked network-access sketch
An 8 kVA hybrid × ≈R88.35 ≈ R707/month floor before energy. If self-use savings do not clear that plus other fixed charges, shrink kVA or improve daytime displacement — inverter size · fixed charges · monthly savings.
Application checklist
- 12-month kWh and tariff code.
- Proposed inverter kVA and NRS family.
- Who files SSEG and pays for the bi-directional meter.
- Zero-export plan if energising early — zero-export · SSEG steps.
Coastal install notes
Humidity and salt air favour indoor electronics and correct IP ratings; pair with SPD scope — indoor vs outdoor · surge / lightning.
Compare the big four export credits (incl. VAT guides)
| Metro | Export guide | Extra trap |
|---|---|---|
| eThekwini | ≈184.60 c | Network-access R/kVA |
| Cape Town | ≈152.93 c | Home User + AMI admin |
| City Power | ≈143.29 c | Prepaid → TOU conventional |
| Tshwane | ≈108 c (RfD) | FAQ may show older c/kWh |
None of these replace self-use against 350–450 c-class import — Cape Town TOU · feed-in hub answer.
Installer briefs for Durban should show network-access R/month next to the savings headline. If that line is missing, the quote is unfinished — read a quote · red flags.
Humidity, SPDs and claims
Coastal corrosion accelerates outdoor failures. Pair right-sized kVA with indoor plant rooms where possible and documented SPDs — surge · insurance.

EV and heat-pump diversity in Durban heat
Summer aircon + pool pump + wallbox can force a larger hybrid that then inflates network-access. Prefer load management and staggered timers over kVA inflation — pool pump · aircon · EV load management · NMD.
Finance honesty
Bond or energy-loan maths must subtract ≈R88/kVA·month × inverter kVA plus other fixed charges before calling the deal “cashflow positive.” If the payment only works by ignoring network-access, shrink the system — bond finance · payback · expand later.
Bottom line: eThekwini’s export credit looks generous until R/kVA meets an oversized hybrid. Right-size, self-use, finish the meter paperwork.

Side-by-side with a careless vs careful Durban quote
| Item | Careless | Careful |
|---|---|---|
| Inverter | 12 kVA “for future EV” | 6–8 kVA with load management |
| Network-access /month | ≈R1 060 at ≈R88/kVA | ≈R530–R707 |
| Export assumption | Equals import rate | ≈184.60 c leftovers only |
| Self-use plan | Missing | Timers + usable kWh named |
| Meter / SSEG | “We’ll sort later” | Line items + zero-export interim |
The careful quote often looks more expensive on day one and cheaper on month twelve. Related: 10 kW cost · 5 kW cost · max solar kW.
Small business / Airbnb in eThekwini
Shops and guesthouses feel network-access and demand structures harder. Read commercial lines separately from residential — small business · Airbnb · demand charges · commercial SSEG.
Educational close: Durban’s export credit is attractive on paper; inverter kVA is the silent monthly tax. Design for self-use, publish R/kVA on the cover, finish the bi-directional meter.
Monitoring after go-live in Durban
Watch three numbers weekly: self-use kWh, export kWh, and whether the billed network-access matches the inverter kVA on your CoC. A mismatch means either the wrong tariff code or an amended inverter not filed. Fix paper before you blame panels — monitoring · bill still high · inverter replacement.
Humidity season: re-check SPD indicators and outdoor gland seals at the same time — surge · earthing.
If you later add an EV wallbox, revisit kVA and diversity before the salesman “just upsizes” — that upsize is a monthly R/kVA event here.

Network-access vs energy credit — bill sketch
eThekwini’s residential export credit near ≈184.60 c incl. looks strong next to City Power ≈143.29 c, but network-access on inverter kVA can lift the monthly floor. A quote that celebrates the export rate while hiding kVA charges will mis-rank Durban vs Joburg payback. Always ask for: export c/kWh assumed, network-access R/kVA, and a self-use-only sensitivity — fixed charges · metro tariffs.

Quick questions
Is the network-access charge on my DB size or inverter kVA?
On inverter kVA under the residential net-billing structure described in the NERSA RfD / City practice — confirm on your account.
Can I cash out export credits?
No — credits offset the electricity account under net-billing rules.
Why is eThekwini’s export higher than Joburg’s but still not the main prize?
Because import is still ~2× the export credit; network-access can erase careless oversizing.
