Industrial infrastructure projects, from industrial zones and municipal systems to large construction programmes and transport logistics, often need several megawatts of generation, either during construction or as permanent prime or standby power. Choosing large power generator sets for these projects comes down to five decisions. MPMC, a Shanghai-based manufacturer whose containerised generator sets have been delivered to more than 120 countries and territories, works through each of them with EPC contractors and project owners.

The Five Decisions

1. Power Rating and Duty

MPMC's containerised platform covers single-engine units from 800 kVA to 3,750 kVA, two-engine units from 1,250 kVA to 3,000 kVA and four-engine Scania units at 1,600 kVA. Projects that run their sets continuously should plan on continuous ratings; on MPMC's 18 MW biodiesel project, each Cummins KTA50-GS8 unit is rated 1,200 kW prime and 1,000 kW continuous. Multi-unit parallel stations scale to tens of megawatts.

2. Voltage and Distribution

Low-voltage output at 400 V suits compact sites, while long cable routes benefit from high-voltage generation, which reduces transmission losses across extended project layouts. MPMC's documented options include 6 kV units and the MCLS2000H(S)-1, which delivers 2,000 kVA prime at 11,000 V, with SF6 gas-insulated vacuum circuit breakers and neutral grounding resistors available for high-voltage switchgear.

3. Fuel

Diesel remains the standard, with HVO to EN 15940 and B20 blends supported on selected Cummins models. The same containerised platform runs on natural gas, with electrical efficiency of at least 38% and total energy utilisation of 80% or more with heat recovery, on methanol at 400 kVA, and on biofuel at B35 and above; on MPMC's Indonesian project, B35 biodiesel lowers lifecycle CO2 by up to 85% compared with petroleum diesel.

4. Enclosure and Environment

Open-type OE units suit plant rooms, while containerised SC units are resistant to heat, corrosion and water and ship in ISO container formats. Options include C3 to C5 coating, copper radiators for 50°C ambient and altitude derating calculated for each engine; sprayed products undergo 500 to 700 hours of salt spray testing twice a year, and super-silent containers reach 83.4 dB(A) at 1 m on the MCLS1250 SC.

5. Control, Monitoring and Storage

DSE or DEIF controllers synchronise multiple units for N+X redundancy, and MPMC's self-developed SCADA provides remote monitoring, automated reports and ten years of data retention. Adding HBD-A or HBD-R battery storage lets the generator sets run at efficient load, absorbs peaks and supports grid-forming operation. At ten off-grid concrete batching stations in Dubai, adding an HBD-500-1000 to three 500 kVA generator sets cut daily fuel use by 10.56% and OPEX by about 20% per station.

Large Power Delivered to Infrastructure Projects

MPMC's references show the platform at infrastructure scale, from a 33.5 MW construction rental supply in Saudi Arabia to municipal backup in Libya and 1,243 reefer generator sets powering refrigerated containers on the China-Laos-Thailand railway.

For each project, MPMC provides design consultation, product customisation, CNAS-accredited factory testing from 0% to 110% load, logistics and commissioning support, so EPC contractors receive containerised units ready for sea transport and rapid installation. Generator sets carry a 1-year or 1,000-hour warranty, with engines and alternators supported through their manufacturers' global service networks.
