Summary of Experience

Mark G. Karl, PE (Ret.), has over 42 years of diverse engineering, regulatory, wholesale markets, finance, and strategic planning experience in the regulated and deregulated electricity sectors. 

Mr. Karl spent 23 years at ISO New England. For the past ten years, he served as Vice President of Market Development & Settlements, responsible for the design and development of the New England wholesale electricity markets. In that role, he oversaw the functions of Wholesale Market Design, Demand Resources Strategy, Market Settlements and Analysis, Market Operations Support Services, and the Chief Economist and his Economic Analysis Group.

In previous roles at ISO New England, Mr. Karl served as Senior Director of Resource Adequacy in the ISO’s System Planning Department, where he was responsible for the operation of the Forward Capacity Auction, the development of the load forecast and installed capacity requirements, and the auction qualification process. He also held the position of Director of Market Development and Integration, designing markets and representing the ISO in stakeholder, regulatory, and legislative processes.  

Before joining the ISO in 2000, Mr. Karl was at Duquesne Light Company in Pittsburgh for nearly 20 years.
