Exxon Holliday joined
Exxon in 1978, where he worked for 19 years until 1997, gaining experience in all aspects of the oil and gas industry. Holliday was made operations manager of the Fawley Refinery near Southampton in the UK when he was 30 years old.
British Borneo Oil and Gas In 1998, when British Borneo merged with
Hardy Oil and Gas, Holliday became its international director. He worked at British Borneo for 3 years. Following the merger of National Grid Group plc and Lattice Group plc in October 2002, he took responsibility for the Group's electricity and gas transmission businesses. Holliday became chief executive officer (CEO) of National Grid plc in January 2007. In 2009, Holliday's total compensation for the role of CEO was £2.2 million, consisting of a £929,000 annual salary, and a £1,277,000 bonus. In 2016, Holliday expressed the view that the concept of
baseload was "outdated", as microgrids would become the primary means of production, and large powerplants relegated to supply the remainder. In November 2015, National Grid announced that Holliday would step down as CEO in March 2016, and that
John Pettigrew, the UK executive director who had joined National Grid 25 years earlier, would succeed Holliday. Holliday left National Grid in July 2016.
Magnox Inquiry In March 2017,
Greg Clark MP, the UK
Secretary of State for Energy, established an independent Inquiry into the conduct of a 2012
decommissioning services
procurement process undertaken by the
Nuclear Decommissioning Authority and the reasons why the contract, subsequently awarded to Cavendish Fluor Partnership in 2014, "proved unsustainable". Holliday was asked to lead the Inquiry. Clark asked the Inquiry to take a ‘cradle to grave’ approach beginning with the NDA’s procurement and ending with the contract termination, to review the conduct of the NDA and of government departments, and to "make any recommendations it sees fit". Interim findings were published in October 2017. ==Directorships==
