"On behalf of our current members, we welcome Mr. Hernandez and Mr. Cornelius to our Board of Directors," said ERCOT Board Chair Bill Flores. "Their extensive experience and leadership will add great value to the Board. We look forward to working with them as we continue to address the challenges and complexities of maintaining a reliable and resilient electric grid to power a fast-growing state and to provide opportunities for hardworking Texas families and businesses."
