According to a statement, the investigation will look into whether “NGET breached rules relating to its duty to operate the system in an economic and efficient manner”. The regulator said: “This includes but is not limited to producing and publishing appropriate forecasts of demand,” although Ofgem also stressed the investigation “does not imply that we have made any findings about non-compliance by NGET”. NGET operates the systems for the electricity transmission network across England, Scotland and Wales. Meanwhile the National Grid reported a 4% increase in annual operating profits to £3.5 billion, driven by healthy contributions from its US business.
