Nameplate numbers do not tell the full story. The calculation that determines whether your generator will perform reliably for 20 years is more complex than most suppliers let on.
Adding up the nameplate ratings of your equipment and selecting a generator to match is a starting point, not a methodology. It ignores the dynamic behaviour of electrical loads, the interaction between different load types, and the real-world conditions under which your generator will operate.
The result is either an oversized unit wasting capital and fuel, or an undersized unit that fails under load at the worst possible moment.
A proper load calculation accounts for:
Every EA Power project begins with a site survey conducted by our engineers. We measure actual load profiles, assess equipment characteristics, review existing electrical infrastructure, and model the complete system before specifying a single component. This is not a desktop exercise. It is a rigorous engineering process that forms the foundation of every reliable installation we deliver.
Correct sizing from the outset eliminates the cost of oversizing, reduces fuel consumption, extends engine life, and prevents the catastrophic cost of undersizing. Over a 20-year asset life, the difference between a correctly sized and an incorrectly sized generator can run to tens of thousands of pounds.
