Mark Davidson's approach to practicing in public utilities law has been ‎developed by having represented all facets of utility regulation ‎including utilities, their customers, and the agency that regulates ‎them. He has practiced before regulatory agencies in Colorado, ‎Louisiana, New Mexico, Washington, and Wyoming. As the country moves toward ‎more renewable energy alternatives, his representation of solar and ‎wind energy service providers will be at the forefront of our energy ‎economy both in Colorado and across the nation.‎

Mark's case work has provided him with invaluable ‎experience. Practicing before several regulatory agencies has given ‎him a unique perspective on the regulatory process and the needs of ‎clients. In addition, his work on the bankruptcy of an electric ‎generation and transmission utility provided valuable insights into ‎what it takes to keep a utility financially viable.‎

Mark has participated in numerous significant electric utility ‎rate, resource planning, transmission siting, and cost recovery cases ‎in Colorado over the past 35 years.

Electric Utilities. Represented Cajun Electric Cooperative of Baton Rouge, Louisiana, in nearly all regulatory matters before the ‎Louisiana Public Service Commission, the U.S. Bankruptcy Court for the Middle District of Louisiana, the U.S. ‎District Court, and the 5th Circuit Court of Appeals during the seven-year pendency of Cajun’s Chapter 11 ‎reorganization.‎

Natural Gas. Represented Colorado Natural Gas, Inc. in its acquisition of Eastern Colorado Utilities.‎

Transportation. Represented Lyft in responding to a show cause order from the Colorado Public Utilities Commission.

Telecommunications. Represented competitive local exchange telecommunication companies in the merger of Qwest Corporation and ‎CenturyLink.‎
