DWMR attorneys are advisors, counselors, dealmakers, and advocates for energy companies.


We represent major intrastate and interstate natural gas pipelines, investor-owned electric companies, retail electric providers, power generation companies, transmission and distribution utilities, and other energy and public utility industry participants.

DWMR is composed of some of the most well-known names in the market; they regularly appear before the Railroad Commission and the PUCT, representing most of the largest pipeline companies and investor-owned electric utilities in the state. On the regulated oil and gas side, the team covers the licensing and permitting aspects of everything from extraction to consumer usage. – Chambers USA

In 2011 and 2012, Chambers USA ranked DWMR as a top-tier firm for both electricity and oil and gas, among Texas firms with state energy regulatory law and litigation practices. Our representation of leaders in the energy and public utility industries since the late 1970s gives us a vast depth of understanding of the operation, financial, and legal details of these industries. This wealth of knowledge and the unrivaled depth of our legal team enable us to achieve outstanding results for our clients at an exceptional value in the areas of practice most critical to the energy and public utility industries: regulatory, litigation, appellate, commercial, environmental, and legislative.


DWMR represents energy companies in administrative proceedings before municipalities and a number of state and federal agencies. By working closely with our clients on a broad range of regulatory issues integral to their provision of services, operations management, and commercial transactions, we keep our energy clients abreast of developments in their areas of significant interest and assist with regulatory reporting matters, statute and code compliance, administrative violations, and policy-making proceedings.

Electric Industry

We represent our electric industry clients before municipalities, the Public Utility Commission of Texas, the Louisiana Public Service Commission, the Arkansas Public Service Commission, and the Federal Energy Regulatory Commission. Chambers USA ranked DWMR in Band 1 (top tier) in its Electricity category for Texas firms with state energy regulatory law and litigation practices.
Our attorneys were heavily involved in the many Public Utility Commission of Texas rulemakings and dockets that led to the transition to retail competition in certain areas of the Electric Reliability Council of Texas. DWMR now represents industry participants located in the “deregulated” areas of ERCOT as well as industry participants in areas outside ERCOT in which electric utilities continue to be vertically integrated. We have participated in the development of the competitive generation market in ERCOT and the transition of ERCOT from zonal to nodal and can assist clients navigating the ERCOT markets and protocols.
Our practice is primarily focused in Texas, but because our clients operate in multiple states and are in many cases subject to FERC jurisdiction, our practice has expanded to the public service commissions in the South and Southwest regions and to FERC.
