ES4PS
We engineer power systems — independent of any OE.
From data centre backup to oil & gas custom design — independent engineering from 0.5 MW to 500+ MW.
OUR PHILOSOPHY
Three principles
Independent
Not tied to any OE or dealer. No sales quota — just the right answer.
System-first
Container · acoustic · HVAC · fuel · controls — 7 disciplines together. We define interfaces upfront.
Day-zero
We engage before layout freezes — before equipment is selected. Day-zero engineering.
INDUSTRIES WE SERVE
5 sectors — each with a dedicated approach
WHAT MAKES US DIFFERENT
Standards-flexible engineering
We apply the right combination of EN, KIWA, BS, UL, API and TS standards based on your customer's location and regulator.
For a single fuel tank design we know which of five different standards apply, and when.

Independent of any OE. System-first by design. Engaged from day zero.
A power system is not a single piece of equipment. It is twenty pieces working together — diesel engine, alternator, fuel storage, cooling, exhaust, acoustics, switchgear, controls, fire suppression, instrumentation. When the interfaces between these pieces are left to chance, the system fails on site even though every individual component meets its specification.
ES4PS engineers the whole system. We are not tied to any equipment manufacturer, we carry no sales quota, and we are not an EPC. Our only deliverable is the right answer for your project.
What we do
We provide seven engineering disciplines under one roof, applied with the right combination of international standards (EN, NFPA, IEC, IEEE, API, KIWA, BS, UL, ASHRAE, ASME, TS) for your project’s location, regulator and budget.
Who we serve
We work with OEMs (peer review, second opinion), hyperscale data centre operators, oil & gas owners and EPCs (especially in MENA and Central Asia), healthcare facility groups, industrial plant operators and MEP design houses that need a power systems specialist.
Why ES4PS
- Independent. No exclusive supplier relationships. No sales quota on any product. The recommendation is whatever is right for your site.
- System-first. We define the interfaces between disciplines before equipment is selected — so the integration works on site, not just on the spec sheet.
- Day-zero. We engage before the layout freezes. Preventing problems is faster and cheaper than patching them.
Capacity range
0.5 – 500+ MW, with multi-unit parallel topologies for the upper range. Standby, prime, continuous and data-centre-specific ratings.
Standards flexibility — our key differentiator
For a single fuel tank design we know which of five standards to apply: EN 12285 (EU), KIWA BRL-K903 (NL/EU installer), BS 799 (UK), UL 142 (US) or API 650 (large atmospheric). The choice depends on your customer’s location, regulator and operator preferences. Most engineering firms know only one of these. We know all of them, and when each applies.
