The United Kingdom (UK) Government's 2017 Industrial Strategy outlines a bold plan centred on making the UK one of the most competitive places in the world to start or grow a business, building on the UK's strengths, extending excellence into the future, and closing the gap between the UK's best performing companies, industries, places and people, and those viewed as less productive. In the context of delivering this strategy, from power system reliability and power quality points of view, this paper explores the various challenges and gaps in the Great Britain (GB) electricity distribution system, which is recognised as among the most complex forms of energy exchange that will become the backbone of the emerging digital economy and Industry 4.0. Additionally, the paper also provides recommendations to address the identified challenges.
