Here’s some of the latest action we’re following on the GreenBeat today:

Tessera scrambles to finance solar projects — Two of the company’s projects will cost a combined $4 billion, but it is struggling to get the financing, according to a Reuters analysis. The analysis cites unnamed sources that confirm buyers are asking about acquiring the land and licenses. But if Tessera agrees to sell, it could lose the opportunity to prove its Sun Catcher technology (pictured) if the buyer wants to substitute its own solar products. Another possibility is that it will find a partner willing to support Tessera’s technology on the sites.

Solar’s BrightSource Energy to go public after oilfield project — Ah, another BrightSource IPO prediction. A Reuters article cites a source “close to the company” and points out some new information: pre-IPO, investors consider most important the successful deployment of BrightSource’s solar technology in a 29-megawatt plant at a Chevron oilfield in California. Dow Jones Venture Wire reported BrightSource’s IPO plans in 2011, and other venture capitalists have predicted next year will be BrightSource’s year to go public.

Spectrawatt lays off 100 and closes New York facility — The solar technology company and Intel spinoff blamed harsher than expected winters in Europe for denting demand, the AP reported. But global photovoltaic installations are up 100 percent this year, Greentech Media points out, suggesting that Spectrawatt may have fallen victim to competitive pricing from Chinese companies and U.S. heavyweights First Solar and SunPower.

DOE finalizes $17.1 million loan guarantee for AES Westover — The company is constructing a 20-megawatt energy storage system using advanced lithium-ion batteries, with some cells from A123. The battery-based energy storage project will be based in New York and saves on emissions by becoming a replacement for traditional grid frequency regulation, which usually burns fossil fuels at power plants to balance power generation and consumption on the grid. AES technology promises to use batteries and software to do the same thing for cheaper and with 70 percent less carbon emissions.
