Electric Power Engineers, LLC (“EPE”), a leading consulting engineering firm focused on the power, renewable energy, grid modernization, and energy storage industries, today announced the acquisition of a controlling interest in EPE by Lime Rock New Energy, growth equity investors for the energy transition.  As part of its investment in EPE, Lime Rock New Energy has also committed additional capital to accelerate EPE’s continued growth.

Based in Austin, EPE is squarely focused on the energy transition, providing a range of engineering services for power systems planning, design, grid integration, and regulatory compliance in the United States and international markets.

Ballouz since 2007. Ms. Ballouz will continue to lead EPE and remain a significant minority owner of the company, along with her senior leadership team of Stephanie Badr, Hugo Mena, and Billy Yancey.

Ms. Ballouz said, “When we set EPE’s vision in 2015 on pioneering integrated T&D solutions, our focus became continuously innovating in consulting and software solutions to help our clients through the challenges of building the power grid of the future.  We are very excited with our choice of the Lime Rock New Energy team as our partner with their focus on the energy transition.  Together we intend to accelerate EPE’s growth, reach, and excellence to serve a growing need for expertise necessary to ensure that our power systems reliably and economically drive toward necessary decarbonization goals.”
