Power shortages are necessitating the widespread use of generatorsets(gensets) on construction sites. So, which are the most popular sizes?
Most construction companies opt for gensets of 125 kVA or 250 kVA capacity; only very large sites can use 1,000 kVA capacity, says Naresh Kumar Gupta, Founder Director, Generator Bazaar. “Multiple genset units are preferable to one large unit so that work continues without interruption even if a breakdown occurs.”
“15 kVA to 250 kVA gensets are the most popular forconstruction sites based on the typical load of welding, drilling, cutting tools, lighting, etc,” opines Narsing Agrawal, Vice President, Modern Hiring Service. “Few construction sites use gensets larger than 500 kVA capacity in all.”
“Most companies prefer to place multiple small generators at different points on the site,” continues Agrawal. “Synchronising the power from multiple gensets at one point and then distributing it adds to the cost of cables but is the practice on more confined infrastructure sites like dams or hydroelectric power projects, or when the company has a distribution setup, or wants to make power available at one point.”
