Electric Regulatory

We help our electric industry clients protect themselves and seize opportunities as we work close at hand with them through a wide array of energy and regulatory matters. Whether the setting is a contested case hearing room, a project finance negotiation, or a private business planning consultation, we excel at assisting clients navigate the uncharted technical and economic complexities that continue to present themselves before the Public Utility Commission of Texas (PUCT) and Electric Reliability Council of Texas (ERCOT) as our markets mature and change.

We have extensive experience representing energy clients in proceedings before the PUCT, ERCOT, and the State Office of Administrative Hearings (SOAH), as well as in energy-related litigation. That experience spans the days of traditional cost of service regulation of fully-integrated utilities, the high-stakes proceedings to transition the Texas electric markets from monopoly regulation to competition, and now more than a decade of implementing our restructured markets. We’ve been in the thick of things as ERCOT has developed and refined its nodal market, as the PUCT oversaw large-scale expansion of Texas transmission to take advantage of our renewable resources, and as Texas utilities deployed advanced meters and other smart grid innovations.

With the boom of renewable energy that has followed, our work includes helping developers and lenders answer and address regulatory matters as projects are financed, advising utilities and other industry participants as the grid evolves, and helping landowners protect their rights as new projects are sited. In all of this we continue to advance our clients’ interests and strengthen their energy business in Texas and beyond. We offer clients a combination of agency and courthouse experience, industry knowledge, and a track record of success litigating complex technical and economic disputes.

In 2012, Chambers first added the category “Texas Energy State Regulatory and Litigation (Electricity)” to its directory of leading US practitioners. Jackson Walker was there then. We’ve been there every year since. Our clients know we’re there to stay.
