Mobile power plants are ideal for city- based large construction projects


In a growing number of industrial and construction applications with temporary power needs in London, large standalone generators are being replaced with groups of smaller generators programmed to work in parallel with each other. Known as mobile IPPs (independent power plants) or simply mobile power plants, these flexible solutions are increasingly popular, says UKPN.

ccording to Atlas Copco, the QAC1250, its first 1MW generating unit, was added to its QAC range in response to interest from the rental


and power generation markets. “This model is the realization of the long -


held dream of our loyal QAC users. The had been asking for a 1MW unit in the same box as the well-known and successful Atlas Copco QAC 1000 Model. We basically developed this unit based on their input,” says Júlio Tomé, Product Manager. “The footprint and dimensions are the same, but there’s 25% more power in the box.” Júlio Tomé explains why this unit is in such demand: “The standard model is fully equipped and comes with the most common


features normally seen as options such as the Qc4002 controller for paralleling, dual frequency, coolant heater, battery charger, automatic fuel transfer system, air inlet shut down valve, spark arrestor, as well as heavy- duty protection for the engine, alternator and electrical system. “ Because of its versatility, it can be used on


nearly any type of application, making it suitable for the rental industry. One common application is where it can be used as a tem- porary power supply to industrial plants, and the 1MW is right in-line with the nominal power of transformers. It is also excellent for events, temporary power generation in remote locations, construction sites, mining, refineries, heavy-duty standby power and


“The standard


model has the Qc4002


controller for parallel ing, dual


frequency, automatic fuel transfer system, air inlet shut


down valve & heavy­duty protection for the engine, alternator


and electrical system.”

The QAC 1250 is a dual frequency unit delivering 1250 kVA / 1000 kW of prime power at 50 Hz and 1450kVA / 1150kW at 60Hz. The unit is being used in some of the toughest applications where efficient, quick and reliable power is required. The engine choice for this model is the


KTA50 from CUMMINS, coupled with a Leroy Somer alternator. In addition to Atlas Copco’s innovative QAC cooling concept; the unit has a variable speed electric fan in a dedicated coolant compartment – ensuring the best mixture of size, noise level and power performance on a portable / multi-drop unit, both at high altitudes and higher ambient temperatures. Designed for the extreme weather conditions which are common to the UK, the QAC series generators are built to withstand the most extreme temperatures, and designed to work in all weather conditions. A built-in engine coolant heater ensures


quick and easy start-up in cold conditions, while a variable speed electric cooling fan allows continu ous operation in higher temperature environments, even desert or seaside locations.
