Founded by Roy MacGregor in 2005, Global Energy Group is a Scottish-based service and contracting business with a broad competence in construction and maintenance of equipment for the energy and oil-and-gas sectors. On any given day, the firm says it may be repairing a drilling rig, building a subsea production system, constructing a petrochemical plant, refurbishing a hydro station and building wave and tidal devices. While a third of its development has been due to acquisitions, organic growth and customer-led expansion overseas have helped sales to rise by 71% a year, from £23.6m in 2006 to £119m in 2009.
