Luminant is kicking off 2013 with a new, yet familiar, face as CEO. Mac McFarland, the company's former chief commercial officer, stepped into his new role on Jan. 1.

"It is a privilege to have this opportunity at a great company like Luminant, said McFarland. "I can't say enough about the strength of talent within this organization and the pride our employees take in helping power Texas. I look forward to continuing the Luminant tradition of safe and strong commercial and operational excellence.

McFarland succeeds David Campbell, who resigned effective Dec. 31 to begin a new role as a principal at an energy-focused investment firm in Dallas.

In his previous role, McFarland and his team were responsible for optimizing the dispatch and value of the company's generation fleet; managing the commodity, transportation and emissions requirements for its operating assets; driving asset management, trading and portfolio management in ERCOT; providing oversight of Luminant's state and federal wholesale market design; and leading generation and development activities.

Prior to joining the company, McFarland held leadership roles in the finance, mergers and acquisitions and marketing and trading organizations at Exelon Corporation for nearly 10 years. Before that, he held various commercial finance and engineering positions in technology and architect-engineering-construction firms.
