Msunduzi (Pietermaritzburg) electricity tariffs 2026/27: which scale makes solar pay fastest

Answer first: In Pietermaritzburg the fixed part of the bill matters more than the headline rate. Msunduzi runs three very different domestic structures in 2026/27 — a low energy rate with a heavy per-amp access charge, a new flat-fee alternative, and prepaid straight-line scales with no fixed charge — and solar savings swing by more than R600 a month depending on which one is on your meter.

What NERSA approved for Msunduzi in 2026/27

Msunduzi implemented a 14.6% average increase in 2025/26 and applied for 9.26% for 2026/27. NERSA’s Regulator Executive Committee met on 9 May 2026 and approved tariffs 6.90% higher across the domestic scales, effective 1 July 2026 (NERSA Reasons for Decision, Msunduzi tariffs FY2026/27). Industrial customers buy 67.11% of Msunduzi’s electricity and domestic customers 21.21%, so household tariffs are a small slice of the City’s revenue but the biggest number of accounts.

The Msunduzi register describes the A.1 access charge as “per amp per phase per month” (Msunduzi Approved Register of Tariffs and Charges 2026/27); GridPulse restates the same schedule with VAT included (GridPulse ZA Msunduzi 2026/27 schedule (VAT-inclusive restatement)). The A.2 scale is new in 2026/27 and charges a different energy rate for each supply size: 300.65 c (20 A), 318.67 c (30–40 A), 346.38 c (50–60 A) and 374.09 c (80–100 A), all excl. VAT.

The same 800 kWh month on three scales

Take a 60 A single-phase house using 800 kWh a month — geyser, pool pump, two fridges and a family of four:

At 500 kWh a month the gap widens: about R2 956 on A.1, R2 435 on A.2 and R2 077 on prepaid, incl. VAT. Scale A.1 punishes low-usage homes because the access charge is fixed by breaker size, not by consumption. That is exactly the kind of home a solar system creates.

What a 5 kW hybrid saves in Pietermaritzburg

Pietermaritzburg has a steady but not spectacular solar resource. PVGIS models a north-facing 25° array producing about 1 433 kWh per kWp a year, from about 106 kWh per kWp in November to 128 in July (EU JRC PVGIS v5.2 (1 kWp, 25° north-facing, 14% system loss; run 27 Oct 2026)). The Midlands’ summer cloud keeps yields flatter across the year than on the Highveld. A 5.5 kWp array (ten 550 W panels) on a 5 kW hybrid makes about 657 kWh in an average month, between roughly 583 and 704 kWh.

Assume the household uses 450 kWh of that directly or through a battery, and exports 150 kWh of midday surplus where the meter allows it:

The R100 000 system price sits inside SolarZA’s national 2026 band of R80 000–R120 000 for ten 550 W panels, a 5 kW hybrid and a 5–10 kWh lithium battery installed (SolarZA price guide (updated Jan 2026)); see 5 kW system cost 2026. Export credits are shown excl. VAT, which is how the NERSA schedule prints them.

The scale decision comes before the panel decision

The table makes the point plainly: on Scale A.1 a solar home still pays R1 437 a month in fixed charges (excl. VAT) and each kWh it avoids is worth only 260.59 c. On A.2 the fixed charge falls to R385.23 and each avoided kWh is worth 398.34 c. A 60 A credit customer who installs solar and stays on A.1 leaves about R620 a month on the table compared with A.2.

Two rules in the register shape the choice. Msunduzi allows one free MCB size change every 12 months, so a home that downsizes from 80 A to 60 A after solar cuts its A.1 access charge by R458.40 a month (20 × R22.92 excl. VAT). And a customer who migrates from credit to prepaid cannot migrate back, because the City intends to phase out credit metering (Msunduzi Approved Register of Tariffs and Charges 2026/27). Run the numbers on your own usage before you move — the prepaid route gives the best per-kWh value but rules out export credits.

• Heavy daytime user, wants export credit: A.2 with a bi-directional meter and an approved SSEG connection.
• Evening-heavy household with a battery: prepaid straight-line, inverter set to zero export — zero-export settings · prepaid meters and solar.
• Staying on A.1: drop the breaker to the smallest size your inverter and loads allow, then size solar for self-use only.

Domestic time-of-use: the evening peak is expensive in winter

Msunduzi also prints a domestic time-of-use scale (TD.1) tied to the smart-meter rollout. The basic charge is R124.65 a month excl. VAT plus a R22.93/kVA demand charge. High-season (June–August) energy costs 797.94 c peak, 260.90 c standard and 156.00 c off-peak; low season costs 280.26 c, 202.13 c and 139.08 c, all excl. VAT (NERSA Reasons for Decision, Msunduzi tariffs FY2026/27). Winter peak energy at nearly 8 rand a kWh before VAT is where a battery earns its keep: a 16 kWh pack that carries the house through the morning and evening peaks avoids the most expensive kWh on the schedule. If you are too busy to read the battery guide — get a 16 kWh battery that can be expanded later; see what size battery.

What to bring to an installer in Pietermaritzburg

• Twelve months of statements showing the scale code, breaker size and kWh — the scale decides the design.
• Your supply size in amps. On A.1 every amp costs R26.36 a month incl. VAT.
• A request for an SSEG application with the City before installation, an electrical CoC and an NRS 097-2-1 listed inverter — SSEG application steps · NRS approved inverters.
• Quotes priced on an open, locally supported stack — a 48 V DC battery and a hybrid you can commission and service without a vendor cloud. 48 V DC is the oldest, most proven home hybrid architecture, and spares stay available — open vs closed hybrid stacks.

Pietermaritzburg’s winter is mild enough that June output holds above 110 kWh per kWp, so the Midlands does not need oversized arrays. It needs the right tariff scale and a battery sized for evenings. Compare with Durban on the eThekwini 2026/27 tariff page.

Quick questions

How much did Msunduzi electricity go up in 2026/27?

NERSA approved a 6.90% increase from 1 July 2026, below the 9.26% Msunduzi applied for. The Scale A.1 domestic energy charge moved from 211.98 c to 226.60 c/kWh excl. VAT and the 60 A prepaid straight-line rate from 337.94 c to 361.26 c/kWh excl. VAT.

Why is my Msunduzi fixed charge so high?

Credit-metered homes on Scale A.1 pay a R61.90 basic charge plus R22.92 per amp per phase every month (excl. VAT). On a 60 A single-phase supply that is R1 375.20 in access charges, R1 437.10 in total, before any energy is used.

Which Msunduzi tariff is best for a solar home?

The tariff with the highest energy rate and the lowest fixed charge rewards solar most. The 60 A prepaid straight-line scale (415.45 c/kWh incl. VAT, no fixed charge) gives each solar kWh about 60% more value than Scale A.1 (260.59 c incl. VAT), whose large access charge solar cannot touch.

What does Msunduzi pay for exported solar power?

NERSA’s 2026/27 decision lists the Msunduzi SSEG feed-in tariff at 83.46 c/kWh excl. VAT, up 6.90% from 78.07 c. You need an approved SSEG connection and a bi-directional credit meter to receive it; prepaid meters do not credit exports.
