DENVER, March 5 /PRNewswire/ --

Altira Group LLC -- the pioneer and leader in venture capital and private equity funding for energy technology companies -- announced the closing of its most recent fund, Altira Technology Fund V L.P. The limited partners include institutions that have partnered with Altira since 1996 as well as first time investors.

Fund V will invest US$176 million over the next three years to partner with companies that commercialize technology utilized to increase productivity and efficiency gains throughout the energy value chain. As in previous funds, these companies are focused on the traditional and renewable energy sectors.

Altira has built a successful investing track record, drawing upon a broad and deep understanding of the global energy business, especially energy technology and how it is applied in the field. Current investments, from its active portfolio of over twenty companies, include Southwest Windpower (http://www.windenergy.com), the leading developer and manufacturer of low cost, reliable, micro wind turbines; DeepFlex (http://www.deepflex.com), the only manufacturer of non-metallic composite pipe for use in deepwater development of oil and gas fields; and RigNet (http://www.rig.net), a provider of broadband, plug-and-play data, voice and video networks to offshore rigs and remote locations.

"Global energy demand continues to grow despite soaring energy prices," said Dirk McDermott, Managing Partner. "Our current estimated capacity and reserve development will fall far short of the projected demand in the next 20 years. Technology has been and will continue to be the solution for those challenges. Altira will continue to lead the way in finding, developing and most importantly, commercializing these new technologies."

"We can offer investors financial returns today as our portfolio companies meet the current energy demand challenge. Not 5, 10, or 15 years down the road," said Peter Edwards, Partner at Altira. "We are excited to be partnering with some of the best minds in the energy sector."

Jim Newell, Partner at Altira Group added, "Altira continues to distinguish itself by partnering with its portfolio companies and limited partners. We appreciate the strong commitment of our limited partners. Their support allows us to continue to be patient and diligent, and to find truly transformative companies in this dynamic marketplace."
