Vice President, Project Development

Tim Diehl is a veteran in power plant investment and management. As Director of Corporate Development and Strategy for Vistra Energy (Luminant and TXU Energy), he was responsible for screening, origination, valuation, and the overall deal process for potential investments in solar, wind, CCGT (combined-cycle gas) plants, storage, and waste-to-energy. 

Tim was responsible for the valuation and was a core member of the deal team for Vistra Energy’s May 2017 acquisition of the 180 MW Upton 2 PV solar development project and simultaneous turnkey, fixed price engineering, procurement, and construction (EPC) contract to deliver the plant in May 2018. Tim was active in all phases of project evaluation, negotiation, due diligence, and deal execution, working closely with Vistra Energy’s private equity ownership. 

Tim also built the valuation models and served on the deal team for Luminant’s acquisition of a 2,988 MW combine-cycle gas plant portfolio from NextEra for $1.3 billion, which closed in April 2016. He ran the valuation model for the $350 million acquisition of 1,054 MW CCGT Odessa-Ector power plant from Koch Industries, announced July 2017. Tim was also actively engaged in all aspects of developing and permitting approximately 5,000 MW of combined and simple-cycle brownfield gas plant options, pending economic conditions.

In earlier roles, Tim coordinated Luminant’s periodic plant-performance review process for the CEO and plant directors and evaluated over $250 million of existing-site investment opportunities for the company’s capital management program.

Tim received his MBA from The University of Texas at Austin in 2005, specializing in private equity finance. He also received his BA from The University of Texas at Austin in 1999, majoring in Plan II Honors and Chinese.
