Table 7: Company Developments and Commercial Implications
| Evidence | Commercial effect | Buyer action |
|---|---|---|
| On 13 January 2026, Avtron announced the LC35 and LC20 liquid-cooled load banks for liquid-cooled data centers [4]. | Adds liquid-cooled models rated 500 kW and 720 kW for commissioning work. | Check cooling method and control network before specifying a data center test fleet. |
| On 30 June 2026, Crestchic reported 12,000 kVA of resistive-reactive load bank capacity used to test six generators on a drillship [16]. | Shows demand for large resistive-reactive banks in marine and offshore work. | Confirm the supplier can deliver the kVA and voltage needed at the vessel location. |
| On 15 October 2026, the US Energy Information Administration reported new peak load records in PJM, ERCOT and SPP [24]. | Higher grid loading raises the value of tested standby and peaking generation. | Schedule load tests before the peak season, not during it. |
| On 3 November 2026, the Bundesnetzagentur announced the first long-term capacity auction results, with about 5,160 rMW awarded [25]. | New firm capacity in Germany will need acceptance testing. | Book rental or purchase capacity early in regions with several awarded projects. |

How are the companies positioned?
Suppliers split between those that also run rental fleets and those that mainly sell units for purchase. Crestchic builds containerised banks and runs a rental fleet [13]. Aggreko leases resistive-reactive banks [17]. Sunbelt Rentals adds four rental categories [22]. Avtron, Simplex, Power Prove and Trystar sell banks in portable, stationary, trailer and DC formats [1][11][19][21].
What matters when a buyer qualifies a load bank supplier?
Voltage, frequency, power factor and the safety rating come first. Avtron's LC35 is built to CE standards for EMEA and Asia, while the LC20 is offered in UL or CE versions [4][7]. Control matters next. Avtron's units can be networked up to 250 load banks [4], and Aggreko says several of its units can run from one control panel [17].
Which capabilities distinguish the product offers?
Cooling, voltage reach and control software are the clearest differences. Avtron offers liquid-cooled banks that need less hot-air clearance [3], Simplex lists air or liquid cooling and DC voltages to 2,400 V [11], and Crestchic lists medium-voltage banks up to 33 kV in one ISO container [13]. Power Prove offers the DIGILOAD digital control solution [19].
How does geographic reach affect competition?
Local depots and certified equipment help decide short-notice jobs. Crestchic opened premises in Australia and Sweden in June 2026 [13][15]. Avtron has a factory location in Cleveland and a plant in Reynosa [8], and Trystar is based in Faribault, Minnesota [21]. A supplier close to the site can deliver and commission faster than one shipping from farther away.
