Electronic Loads
Regenerative and dissipative electronic loads that return test energy instead of burning it.
A dissipative load turns test energy into heat, which the building then spends more energy removing. A regenerative one returns most of it. Which is right depends almost entirely on how many hours a year the equipment actually runs.
Both are here, along with the honest arithmetic for deciding between them.

Choosing between them
Utilisation decides, not power
High power used occasionally does not justify regeneration. Moderate power run continuously usually does. Burn-in and life-test floors are where the case is strongest.
Crest factor, not just watts
Loads are specified in kilowatts and used against non-linear devices. Confirm the current the load can actually absorb at your waveform.
The capital cost you might avoid
If adding dissipative load would force a service-entrance or cooling upgrade, that avoided cost belongs in the comparison and usually dominates it.
