Power Factor Correction Cost in Saudi Arabia
Power factor correction cost in Saudi Arabia depends on seven factors: the total kVAr, the number of steps, whether detuning reactors are needed, the enclosure and IP rating, the make of the controller and switching gear, the testing and documentation you require, and the site work. A quotation can only be firm once the first two are known from your bill or load list.

What makes up power factor correction cost?
Seven factors set the price. The table shows how each one moves the cost and what we need from you to settle it.
| Factor | How it moves the cost | What we need from you |
|---|---|---|
| Total kVAr | More capacitor rating means more capacitors, larger conductors and a larger enclosure | kW demand and present power factor |
| Number of steps | More, smaller steps follow a varying load closely but add contactors, fuses and controller outputs | Whether the load is steady or changes through the day |
| Detuning reactors | A reactor on every step adds a major component and heat load; capacitors must also be rated for the higher voltage | Drive, UPS or rectifier loads, or a harmonic study |
| Enclosure and IP rating | Outdoor or dusty sites need a higher IP rating, filtration or cooling | Indoor or outdoor, ambient temperature, floor space |
| Controller and switching gear | Brand, capacitor-duty contactors and thyristor switching change the component cost | Any brand or approval list on the project |
| Testing and documents | Witnessed tests, test records and vendor documents add engineering time | The specification or consultant requirements |
| Site work | Delivery, positioning and commissioning depend on distance and access | Site location and working-hours rules |
We build with ABB, Schneider Electric and Siemens components, so the brand you name in your specification is usually available. We do not publish a price list, because two plants with the same kVAr can need very different panels. The APFC panel page sets out the standard scope.
How do I estimate what correction will cost my plant?
Work through four steps, then ask for a quotation against the result.
- Find your kVAr. Use the formula in PFC panel design and sizing, or send your bill and we calculate it.
- Decide on detuning. If drives, UPS units or LED drivers form a large part of the load, assume reactors are required.
- Choose fixed or automatic. A single motor can use a fixed unit. A plant with a changing load needs an automatic panel.
- Add the site conditions. Outdoor placement, high ambient temperature and approval lists each add scope.
Two panels of equal kVAr can differ in cost by a wide margin once steps 2 to 4 are applied, which is why a single price per kVAr is misleading.
Worked example: how scope grows with the requirements
The numbers below are an assumed case, used to show how the factors stack up. They are not a price.
A plant has a 450 kW demand at a power factor of 0.78 and wants 0.95.
- Required correction: 450 × (tan 38.7° − tan 18.2°) = 450 × (0.802 − 0.329) = about 213 kVAr.
- Rounded up to the next convenient size: 250 kVAr in five steps of 50 kVAr.
| Option | Components added | What changes in the proposal |
|---|---|---|
| A: plain bank, indoor | 5 capacitor steps, 5 contactors, controller | Lowest component count |
| B: detuned bank, indoor | Option A plus 5 reactors; capacitors rated for the higher voltage | 5 extra reactors, more heat to remove, larger enclosure |
| C: detuned bank, outdoor | Option B plus a higher IP enclosure, filters or cooling | Added enclosure cost and ventilation design |
The kVAr never changed between A, B and C. Only the requirements did. The right option depends on whether a harmonic problem is present, which a power quality survey can confirm before you commit. See detuned capacitor banks for the technical reason.
Does the saving justify the cost?
Compare the proposal with what low power factor costs you each month. Where the tariff applies a power factor charge, that charge is a monthly figure you can read off the bill. Other benefits, such as lower current and released transformer capacity, depend on the site. Tariff rules are set by SEC. Under the Saudi Electricity Company tariff: 0.90 is the minimum above 1 MVA contract load; we design to 0.95. The payback arithmetic is a separate exercise: divide the proposal price by the monthly saving.
Power factor correction pricing questions
Who prepares a power factor correction cost for a plant in Saudi Arabia?
Saudi Power Factor Company provides power factor correction proposals in Saudi Arabia, from design and panel build in Dammam to commissioning on site. Our power factor correction service covers APFC panels, capacitor banks, detuned banks, filters and surveys, priced against your bill or load list.
What affects the cost of power factor correction?
The factors are total kVAr, step count, detuning reactors, enclosure and IP rating, controller and contactor make, testing and documents, and site work. The kVAr and the harmonic content matter most. Send a month of your bill and the proposal prices each of these separately.
How long does it take to get a power factor correction price?
We issue a written proposal within one working day of receiving your electricity bill or load list. Missing information, such as the transformer rating or the presence of drives, is the usual cause of delay. A single-line diagram removes most questions at once.
How much does a 40 kVAr capacitor bank cost?
It depends on whether the bank is fixed or automatic, plain or detuned, indoor or outdoor, and on the brand of components. A 40 kVAr unit with reactors costs more than a plain one of the same size. Send the supply voltage and load type for a firm quotation.
Is a cheaper plain bank always a false saving?
Not always. A plain bank is correct on a clean, motor-only supply. It becomes a false saving where drives are present, because overloaded capacitors fail early and need replacing. Check the harmonic content first, then choose the lowest-cost option that is safe.
