The Week in Cleantech – Jan. 21 – 27

Clean technology sectors including Energy Storage, Energy Efficiency, and Solar saw exciting new investments last week:

Leyden Energy‘s existing investors, including Lightspeed Venture Partners, NEA, Sigma Partners, and Walden International Venture Partners, all signed up to provide the company $10 million more in Series C equity capital. Leyden is seeking to commercialize new lithium-based battery technology, certain aspects of which it originally licensed from DuPont.

HVAC energy management software developer BuildingIQ gained two new corporate investors in Aster Capital and Siemens Venture Capital. Aster capital is a corporate venturing firm sponsored by Schneider Electric, Alstom, and Solvay. The investors combined to bring BuildingIQ $9 million in new equity capital.

The downstream solar market saw continued confidence from investors when OneRoof Energy, a residential PV financing and installation company based in California, raised $30 million in new capital from existing investor Hanwha Corporation. Hanwha has been extremely active of late, with investments in Silent Power and tenKsolar, as well as its acquisition of Q-Cells after that company’s insolvency. OneRoof Energy seeks to join the likes of SolarCity, SunRun, Sungevity, and Clean Power Finance with tax-equity-backed project funding to fuel its pipeline of residential customers, but the company has yet to announce the closing of a hoped-for $100 million fund it discussed openly back in July.

Xtreme Power delivered some exciting news last week, as its 36 megawatt energy storage system went online backing up Duke Energy’s Notrees wind farm in west Texas. Xtreme will continue to manage the unit for Duke, which sells power from the wind farm to Wal-Mart for its renewable power initiatives.
