ALBUQUERQUE, New Mexico, November 16, 2011 — Unirac, Inc., a Hilti Group Company and North America's leading provider of infrastructure for solar power systems, today announced Peter Lorenz has been appointed as the company's new chief executive officer. Lorenz succeeds Douglas May who retired from the company at the end of October.

Peter comes to Unirac from Quanta Services, a leading specialized contracting services company in the electric power, natural gas and telecommunications industries, where he served as President of Quanta Renewable Energy Services. Under Lorenz's leadership, Quanta became a leading solar EPC company with more than 120 MW of solar projects installed over the last three years.

According to Unirac's Chairman of the Board, Ewald Hoelker, "We're delighted that an industry professional of Peter's caliber is taking over the reins at Unirac.

During his tenure, Quanta gained recognition as one of the leading solar EPC firms in the United States. The board is confident Peter has the vision, passion and experience to take Unirac to the next level, building on the excellent foundation Doug May and the senior management put in place over the last five years."

"The Unirac name is synonymous with quality and leading-edge innovation, and the Hilti Group stands for superior performance and endurance," said Lorenz. "I am excited to join the best team in the industry and lead Unirac through the next phase of its growth. We will continue to deliver high quality and innovative solutions that enable our customers to lower the total cost of ownership in residential, commercial and utility. This will further solidify our leadership position in the marketplace."

Prior to his tenure at Quanta Services, Lorenz was employed seven years with McKinsey & Company in Houston as an Associate Principal where he served clients in the electric power and renewable energy industry across multiple continents and helped build McKinsey's global solar competence. Before that, he had several finance assignments with Royal Dutch Shell in London from 1996 to 1999 and helped build Shell Solar's global business as the company's finance manager.
