In his 43 year career as a lawyer Wren has successfully represented numerous infrastructure industries and their customers, including electricity, natural gas, nuclear, renewable energy, cogeneration, telecommunications, and water. He has represented many of the most successful vertically integrated electric utilities, natural gas transmission and distribution utilities, water utilities, telecommunications companies and electric transmission and distribution utilities in a wide variety of commercial, regulatory and litigation matters in Texas and surrounding states. Working on behalf of numerous industry leaders over his career, Mr. Wren’s legal work has involved many path breaking and industry first engagements arising from the legal, regulatory and commercial developments and challenges affecting infrastructure industries, and especially electricity, nuclear, natural gas, and telecommunications from 1979 to the present.

In addition to his infrastructure practice, Mr. Wren has been highly effective in representing many non-utility participants in the infrastructure and energy markets including power generation companies, retail electric providers, owners and developers of utility scale renewable generation facilities, developers and customers of distributed generation, developers and customers of micro-grids, electric cooperatives, and large wholesale and retail consumers of electricity. Mr. Wren has also represented many other market participants in infrastructure industries including natural gas producers, natural gas distribution companies and pipelines, as well as customers and counterparties of electric utilities and power generation companies including oil and gas producers, large industrial manufacturers, governmental entities and a Trauma 1 Level hospital.

Mr. Wren is experienced and knowledgeable about all legal and business aspects of the infrastructure industries, and uses that experience and knowledge to obtain extraordinary results whether using litigation, negotiating, dispute resolution, advocacy, drafting or strategic planning skills. Wren for many years served as Chair or Vice-Chair of the Electricity Committee of the ABA’s Infrastructure and Regulated Industries (IRIS) Section and as Editor of Infrastructure, the Section’s quarterly periodical. As Chair of the Electricity Committee of IRIS, he spoke frequently to the council group of IRIS and industry lawyers who represent regulated and infrastructure industries, where he addressed recent developments in electricity law, renewable energy, utility law, regulated industries and energy markets. In 2018, the IRIS leadership asked Wren to write an article on the history of the electricity industry, to celebrate the 100 year anniversary of IRIS. The article appears in the winter 2018 issue of Infrastructure, as A Century Plus of Power and Light, Infrastructure, Vol. 57, No.2 (Winter), with Mark Strain and Everett Britt.
