CoCT New Power Tariffs

City of Cape Town’s New Pre-Paid Electricity Tariffs: Why Solar Is the Smart Move for Cape Town Homes in 2026

New CoCT Power Tariffs have made Cape Town residents on pre-paid electricity feel the pinch. The City of Cape Town’s 2026/27 residential Domestic tariffs (effective from 1 July 2026) have pushed Block 1 (0–600 kWh) to approximately R4.13–R4.14 per unit and Block 2 (above 600 kWh) to about R4.93–R4.94 per unit (VAT inclusive).

These rates, combined with daily service and wires charges on prepaid meters, mean many households are paying significantly more for the same electricity than just a few years ago. For average Cape Town families — especially those with geysers, pools, air-conditioning, or higher evening usage — the monthly electricity bill has become one of the biggest household expenses.

Understanding the New CoCT Power Tariffs:

Pre-Paid Blocks

• Block 1 (0–600 kWh): ±R4.13 per kWh
• Block 2 (Above 600 kWh): ±R4.93 per kWh

The New CoCT Power Tariffs block system tracks your total purchases for the calendar month. Buying in bulk does not get you a better rate — it can simply push you into the more expensive Block 2 sooner. Staying under 600 kWh is the only way to keep the lower rate, but for many homes this is difficult without major lifestyle changes.

Why Solar + Battery Makes More Sense Than Ever in Cape Town

With electricity now hovering around R4–R5 per unit (and fixed charges still applying), the payback period on a properly designed solar system has shortened dramatically. Every unit your panels produce and you use yourself is a unit you no longer buy from the City at these elevated rates.

Key advantages for Cape Town homeowners right now:

• High self-consumption value — Offsetting R4.13–R4.93 electricity delivers strong monthly savings.
• Battery storage — Use solar energy in the evening and overnight instead of drawing expensive grid power.
• Load-shedding resilience — Even when the grid is stable, batteries provide security during local outages or future stages.
• Zero-export or limited-export options — Many systems can be configured to prioritise self-use while remaining compliant with City of Cape Town requirements.
• Long-term protection — Tariffs tend to rise over time. Locking in your own generation hedges against future increases.

Real Impact for Typical Cape Town Households

A household using 800–1,200 kWh per month can easily see substantial monthly savings once a correctly sized solar + battery system is installed. The higher the portion of your usage that comes from your own panels and batteries, the less you pay at the new Block 1 and Block 2 rates.

Hybrid systems (popular local brands such as Sunsynk, Deye, Fox ESS, and others) allow you to prioritise solar, store excess in batteries, and only draw from the grid when necessary — keeping more of your consumption in the cheaper (or free) category.

Is Now the Right Time?

Yes. Electricity prices have moved sharply higher, while solar panel and battery prices have become more accessible. Combined with Cape Town’s excellent solar resource, the economics favour installation more than they did a few years ago.

At Sundial Solar we specialise in residential and commercial hybrid solar systems across the Cape Town area. We design systems that maximise self-consumption under the current City of Cape Town tariffs, handle the technical and compliance side, and help you understand realistic savings based on your actual usage.

If you’re tired of watching your pre-paid units disappear faster every month, it’s time to switch.
