ISO-NE announces changes in Finance leadership

ISO New England today announced the retirement of Bob Ludlow, vice president, chief financial and compliance officer. Kelly Reyngold will succeed Ludlow as vice president and chief financial officer on Jan. 1, 2026. 

Ludlow has been with ISO New England since just prior to its inception in 1997, when he joined the leadership team establishing the ISO and leading the development of the company’s financial, compliance, cash clearing, market and credit risk management, strategic planning, and treasury management programs. He served as the lead ISO executive for the company’s Audit and Finance Committee and the Budget and Finance Committee of the New England Power Pool.  

“Bob has been a key leader of the ISO since its inception. He has successfully steered our budget and compliance operations throughout 28 years of growth and significant change, providing wise counsel through strong financial acumen and a great sense of humor,” said Gordon van Welie, ISO New England’s president and CEO. 

Reyngold joined the ISO in 2002 as a staff accountant before progressing through roles of increasing responsibility, including controller and, most recently, director of accounting.  

In her previous roles, she oversaw treasury management, the preparation of financial statements, stakeholder communication regarding the company’s annual budget, and administration of the Billing Policy, among other duties.  

Reyngold assumes her new position with over 30 years of experience in the accounting field. Prior to joining the ISO, she gained extensive experience within public accounting and advanced through a variety of accounting roles in both private and public companies. She holds a bachelor of science degree in accounting from Bentley University and is a certified public accountant. She has developed expertise in financial reporting, compliance, and operational finance, giving her a broad perspective on the challenges organizations face across industries. She now applies this background to support the ISO’s commitment to transparency, efficiency, and strong financial stewardship.

“Kelly’s extensive experience and leadership in managing her team to produce timely and accurate budget and financial results makes her the ideal person to lead ISO New England’s financial departments through the region’s energy transition,” said Vamsi Chadalavada, ISO New England’s executive vice president and chief operating officer, who will assume CEO duties on Jan. 1. “I look forward to working with Kelly in her new role.”
