Responsible AI Summit North America: Day 2 - Wednesday, June 24, 2026

12:10 PM Presentation – Enabling AI at Workforce Scale: The Story of Xcel Energy

Scaling AI across a workforce introduces real challenges around accountability, trust, and responsible use. In this session, Mark Lesiw, AI Enablement Program Owner at Xcel Energy, shares how Xcel Energy increased active enterprise AI usage from 33% to over 90% across 27,000 employees in under 12 months. Mark introduces Return on Employee, a term he uses to define AI value across a workforce, focusing on productivity, confidence, and decision quality, alongside traditional Return on Investment. He explains how Responsible AI was embedded from the start through literacy, tool-level guardrails, and human-in-the-loop design so that AI use could scale safely and deliver lasting business value.

• Responsible AI starts with tool design.

• Return on Employee makes AI value clear and human.

• Accountability stays with people, not systems.
