Caitlin M. Shields

Office Denver

Caitlin is passionate about energy. As a trusted advisor to clients in a variety of network industries, she infuses every engagement with her own energy and passion. Over the past decade, Caitlin has been at the forefront of many emerging trends in the power sector and across network industries. Utilities, telecommunication companies, large customers, railroads, and other stakeholders routinely seek her counsel in state public utility commission proceedings and related federal and court proceedings.

With a particular interest in the convergence of energy and environmental law, her work often involves ratemaking, resource planning, and competition/regulated monopoly issues. Caitlin devotes a significant portion of her practice to providing strategic policy guidance, and finding creative regulatory solutions to issues posed by new and emerging technologies.

Caitlin’s interest in energy and environment aligns with her personal passion for the outdoors and travel. As an avid cyclist and skier, she’s usually willing to take business meetings on the slopes when she’s not in a hearing room.
