The AlwaysOn Network recently announced their Third Annual List of the GoingGreen 100 Top Private Companies of 2009.  The award recognizes the top private greentech companies that are creating new business opportunities and transforming the world’s largest industries to improve sustainability.Among the hundreds of companies evaluated, They selected the Oakland California-based, Brightsource Energy, a provider of solar energy to utlility companies, as the overall winner. There were category winners as well, in the areas of Biofuels, Clean Techology (not solar or biofuel), Clean Manufacturing, Energy Efficiency, Energy Storage, Green Transportation, Green Materials, Waste Management, Solar Energy, and Water Technology.

The companies were evaluated based on assessments of the breakthrough potential of their technologies, market size, management team, and investors. Both startups and well-established firms were evaluated. AlwaysOn surveyed hundreds of venture investors, investment bankers and industry experts, receiving more than 400 nominations. The AlwaysOn editorial team and a panel of industry experts from KPMG, Morgan Stanley, Manatt, Silicon Valley Bank, Goodwin Procter, The Artimis Project, Revolution Partners and Bridge Bank evaluated the nominations based on five criteria: innovation, market potential, commercialization, stakeholder value, and media buzz.

BrightSource Energy Named The Overall Leader
Overall Winner BrightSource Energy incorporates several key features that distinguish them from all other solar thermal processes. (1) They use a “power tower,” that is, one central steam boiler, where temperatures rise to over 500 degrees F. This is hot enough for the water to be condensed on the other side of the generator turbine using only an air cooler, which is far less expensive to build and operate. (2) The central boiler is served by a field of mirrors that reflect onto it; this solar field, unlike competing solar thermal technologies, does not require any plumbing into the field for thermal transfer fluid. (3) The mirrors in the solar field sit on a single pole, with individual two-axis tracking mechanisms on each mirror. Because there is nothing in the ground but one pole per mirror, the solar field can remain irregular and unimproved, also greatly lowering costs. In addition to their superior technology, BrightSource has taken the lead in securing substantial project financing and approvals, signing the world’s largest solar deal with Edison in Southern California earlier this year. The company is poised to become a significant supplier of electricity.  electricity at scale in the near future. BrightSource has been featured in the Las Vegas Sun, San Franciso Chronicle, New York Times, Greentech Media, San Jose Mercury News, and The World.

The AlwaysOn GoingGreen 100 Top Private Companies for 2009 were honored at GoingGreen West 2009 San Francisco last month.   A full list of all the GoingGreen 100 Top Private Companies can be found on the AlwaysOn website.

Note From The Editor: The companies on the list should be applauded for their achievements.  However, it is important to note that while  I was researching the winners, I discovered that a few of the investment companies that participated in the evaluation process, were investors in a few of the winning companies. For instance, Morgan Stanley is listed as an investor on clean coal company, Accelergy’s web site. Accerlergy was the Clean Energy category winner.  Morgan Stanley is also listed as an investor on BrightSource Energy’s web site.  BrightSource was the overall winner of the Going Green Top 100.  That potential glitch in the selection process also caught the attention of readers a last month when the Global Cleantech 100 listSeveral readers on our site and participants on some linkedin green groups raised some questions regarding the interests of the voters and their investments in the companies that they selected as winners.

It is my hope that the sponsors of these lists begin to reevaluate this practice of having investors and other potentially biased parties playing a major role in the assessment of these companies.  I fear if they do not, they risk having the value of these lists significantly devalued.   I hope in the future, AlwaysOn will consider providing readers with more insight into their methodology.  While it is a different type of list,  one thing I liked about Newsweek’s First Annual Green Rankings is the detail they provided in their explaination about the methodology. Also none of the panelist appeared to be affiliated with the companies being evaluated.  I believe transparency about the process engenders trust with the readers.

So, what companies do you think should have been included in the GoingGreen 100 Top Private Companies list and what you your think about the selection process.
