Antony Johnson’s association with National Grid started in 1990 in the newly privatised Electricity Industry. After initially describing the structure of the industry at that time, he will go on to review the changes and challenges that have taken place over the last 30 years. Starting with the fundamentals of system operation followed by the dash for gas and the growth of combined cycle gas turbines in the 1990’s, he will then move on to the growth of wind generation and the technical challenges arising from the integration of this technology together with the expansion of Offshore Transmission. This coupled with the growth of Embedded Generation, legislative changes and European developments will lead to the current day where he will focus on the modern day challenges of further embedded generation, storage and the need for Grid Forming capabilities. This presentation will very much focus on his own experiences especially in the development of Grid Code requirements which he has been working on for many years.
