My ZESA Quotation Is Too Expensive: What Are My Options?

ZESA Quotation Is Too Expensive

Receiving a connection quotation far above what you budgeted is one of the most common experiences in Zimbabwe, and most people respond in one of two unhelpful ways: they abandon the project, or they pay a figure that was never properly examined.

There is usually a third path. In fourteen years of reviewing connection quotations we have found that a significant proportion contain scope that can legitimately be reduced — and where they cannot, there are structures that make the same cost affordable.

First: understand what you have been quoted

Before deciding anything, separate the quotation into its parts. A typical quote contains an application fee, a capital contribution, a service connection cost, and — where applicable — a transformer and line extension.

Some of these are fixed by tariff and are not negotiable. Others follow directly from design decisions that were based on the information you supplied. That distinction is where the opportunity lies, and it is why we always start by reading the quotation line by line. Our guide to why quotes come out so high explains what each item means.

Option one: check whether the load was over-specified

This is the most common source of unnecessary cost, and it originates with the applicant rather than the utility.

Applicants routinely declare every appliance they might ever install, at full rating, all running simultaneously. Real installations never behave that way. A properly calculated load applies diversity — the recognition that not everything runs at once — and often produces a materially smaller figure.

Because transformer size is driven by assessed load, an over-declared load can push a project from, say, a 50kVA transformer to a 100kVA unit. That single step can change the affordability of the whole project. A formal load assessment is inexpensive relative to what it can save.

Option two: share the connection

If a transformer is the item making your quotation unaffordable, the arithmetic changes completely when the cost is shared.

A transformer sized to serve several premises costs considerably less than several separate connections, and only slightly more than one. Where three or four neighbouring stands or farms all need power, a shared connection commonly reduces each party’s cost substantially.

The barrier is rarely technical — it is trust, and the fear of disputes later about who owns what. Those concerns are legitimate and entirely manageable with a written contribution agreement drawn up before any money changes hands. We cover this fully in sharing a transformer with neighbours and who owns the transformer you paid for.

Option three: revisit the design

Several design decisions influence cost and are worth examining:

Meter and service position. Long service runs are expensive, and they also cause voltage drop. Repositioning the point of supply can shorten the run considerably.

Routing. The shortest line route is not always the cheapest once terrain, road crossings and wayleave negotiations are considered. An alternative route can sometimes be cheaper despite being longer.

Phasing. Some projects can be built in stages — establishing supply at a lower capacity now and reinforcing later as demand grows. This is not always possible, but where it is, it converts an impossible lump sum into manageable stages.

Option four: phase the payment rather than the project

Where the scope genuinely cannot be reduced, the question becomes funding rather than engineering. Pooled contribution arrangements, staged payments aligned to project milestones, and bringing additional parties into a shared connection are all routes we have used to get projects built that would otherwise have stalled.

What is not worth trying

Some approaches waste time or create real risk, and it is worth saying so plainly.

Attempting to negotiate tariff-fixed items is not productive — those figures are set by approved tariffs, not by the depot. Sourcing second-hand transformers of unknown provenance usually fails on specification and testing, and can leave you with equipment ZETDC will not energise. Informal arrangements to connect via a neighbour’s supply without proper agreement and metering create disputes, safety hazards and, frequently, disconnection.

Have the quotation reviewed

If your quotation is more than you can fund, the worst outcome is abandoning a project that could have proceeded. A review establishes quickly whether the scope reflects your actual requirement, whether the design is the most economical option, and whether sharing is viable in your location.

Send us your quotation and we will tell you honestly what can and cannot be changed. Where nothing can be reduced, we will say so — that answer is worth having too.

What we look for when reviewing a quotation

A review is not guesswork. There are specific things we check, in order.

Does the declared load match the actual installation? We compare the load schedule submitted with the equipment genuinely being installed. Discrepancies here are common and expensive.

Is the transformer sized to the assessed demand or to the declared connected load? These are different numbers, and the gap between them is often a full transformer size.

Is the service route the shortest practical one? Meter positions are often chosen for convenience rather than cost, and moving the point of supply can remove several spans.

Has spare capacity nearby been considered? Connecting to an existing transformer with headroom is dramatically cheaper than a new unit, and this option is not always explored.

Is anyone else in the area applying? Two separate applications for adjacent properties within a few months of each other is a shared connection that nobody proposed.

What a review realistically achieves

We want to be straight about expectations. Roughly speaking, reviews fall into three outcomes.

Some quotations turn out to be correctly scoped and cannot be reduced. In that case the honest answer is that the figure is what it is, and the question becomes funding rather than engineering.

Some contain a sizing or scope issue that, once corrected, brings the figure down meaningfully — most often through transformer size or service route.

And some are unchangeable individually but become affordable when shared. This is the most common outcome on rural and farm connections, and it is the one applicants least often consider on their own.
