Beacon Power Corp (BCON) announced that it has executed a contract with the California Energy Commission to demonstrate an advanced energy storage solution for frequency regulation and grid stability. At a business meeting on December 1, 2004, the California Energy Commission had given its approval to the project, leading to contract negotiations that have now been finalized. The contract is expected to produce approximately $1.2 million of revenue, with the majority of it in 2005.

SatCon Technology Corporation (SATC) announced that it has received a follow-on purchase order for a second 2200 kVA Rotary Uninterruptible Power Supply (RUPS) on a government contract valued in excess of $1.1 million. SatCon's StarSine(TM) Rotary UPS is designed to provide both high quality electrical power during normal operation, as well as prevent any interruption of electricity to critical manufacturing processes, telecommunication centers, data centers, and healthcare facilities in the event of power grid failures such as black-outs and brown-outs. The RUPS is connected directly to SatCon's patented flywheel for short duration power disturbances and is integrated...

Beacon Power Corp (BCON) was up over 147% at the close today. This move was primarily based on two project wins. One with the New York State Energy Research and Development Authority and the other with the California Energy Commission. The projects would have Beacon Power provide grid frequency regulation and reactive power by utilizing its flywheel energy storage system. The final terms and conditions of the projects have not been disclosed.

Active Power Inc (ACPW) announced the details behind its latest breakthrough in alternative energy storage. The new technology, based upon the innovative combination of several mature technologies, constitutes a monumental achievement in energy storage by providing the extended runtimes of lead-acid batteries without any of the well-known shortcomings of these cells. This Thermal and Compressed Air Storage (TACAS) technology will be incorporated into Active Power's newest product that will begin shipping as an alpha unit late this year, the CleanSource® XR.

7.17.09 Storage Week John Petersen Infocast’s Storage Week was all I had hoped it would be, and more. While I thoroughly enjoyed serving on three discussion panels and was warmly received by roughly 250 attendees, including executives of companies that I've occasionally criticized, the most important value for me came from the opportunity to hear four days of high-level presentations by industry executives, national thought leaders and policymakers who repeatedly stressed that: From a utility perspective grid-based energy storage is the functional equivalent of an instantly...

John Petersen Tom Lehrer is frequently credited with a quip that perfectly summarizes my feeling about the financial markets in the third quarter, "Apart from that Mrs. Lincoln, how did you enjoy the play?" During the quarter we were given box seats to classic political opera in two acts. Act One was set in Washington DC while Act Two moved to Europe so we could hear the same tortured songs of woe in a different language. We all know the opera has to end with the immensely popular "Kick the Can Chorus," but we suspended disbelief, bought into...

John Petersen With only a couple trading days left in 2009, this is as good a time as any for a performance review. The predictions I made at this time last year were pretty solid with an 80% accuracy rate on price direction. For the year, a $1,000 investment in each of my green star companies would have yielded a portfolio appreciation of 67%, which handily beat the broader market indices. That being said, my star and caution ratings were a good deal less prescient because I seriously underestimated the potential of both Maxwell Technologies (MXWL) and Active...

Beacon Power Corp (BCON) announced that it recently delivered, installed and connected a scale-power Smart Energy Matrix demonstration system to the electricity grid in Amsterdam, New York. After arriving at the site, the system was connected and turned up to full power, and is now following and responding to live ISO-specified requirements to demonstrate frequency regulation. The project, jointly funded by the New York State Energy Research and Development Authority (NYSERDA) and the U.S. Department of Energy (DOE) Energy Storage Program, is the second such scale-power system Beacon has delivered, in addition to a similar system in California. ...

Tom Konrad CFA How material is the failure of one of Beacon Power's (BCON) flywheels on July 27?<a href="http://www.altenergystocks.com/comm/content/beacon-power-corporation/" beacon="" power's="" (bcon) Last week, I published an article Four Clean Energy Value Stocks I'm Buying Now, including Beacon Power as one of the four.  My rationale for including Beacon was: Beacon has been operating their first commercial scale 20MW flywheel energy storage plant  since early this year without mishap, achieving full capacity in June.  They are set to begin construction of their second 20MW plant later this year, 54% of...

It’s official! Cleantech, the sixth industrial revolution, has arrived on time and in the midst of extraordinary crisis. Like every good revolution, blood is flowing in the streets; the guillotine is en route to Wall Street and the mob is so busy plotting retribution for the excesses of the past that most have no time to consider the future. But as yesterday’s dynasties decay, crumble and fall, a new generation of visionaries is already building on the wreckage of the past. These are indeed troubled times that bear an eerie resemblance to the opening sentence from A Tale of...

America’s electric power grid is subject to immense inefficiencies that arise from the interplay between centralized power generation, local power consumption and on demand utility service. To put things into a broad perspective, the nameplate capacity of U.S. generating facilities is about 1 million Megawatts (MW), so if all of our power plants ran 24/7 we would have a theoretical annual generating capacity of 8.7 billion Megawatt-hours (MWh). Since demand for electricity fluctuates on both a daily and seasonal basis, total electric power generation in 2007 was only 4.2 billion MWh, or less than 50% of nameplate...

John Petersen The next couple months are shaping up as a time of extraordinary change in the energy storage sector. Events that will drive the change include: Press reports indicate that the Department of Energy will be ready to announce it's preliminary decisions on the allocation of $2 billion in ARRA battery manufacturing grants sometime this week; We've seen numerous reports on automaker's plans to begin manufacturing PHEVs and EVs in limited volumes for testing and demonstration purposes; New tailpipe emission standards in Europe and accelerated CAFE standards...

Beacon Power Corp (BCON) has announced that it has been awarded a contract from Bechtel Bettis, Inc., to design and deliver an advanced flywheel-based power system demonstration unit. Bill Capp, Beacon Power president and CEO says "...Although this contract is not considered material from a revenue standpoint, these types of projects are significant because they extend our technology portfolio, help defray operating expenses, and can lead to other business opportunities."

In June, I wrote how intermittent power sources such as photovoltaics and wind would have to compete with baseload technologies such as IGCC "Clean Coal" and nuclear for capacity on the grid.  The key problem is that neither baseload technologies nor intermittent technologies are able to match themselves to the fluctuations of demand.  This creates a need for technologies which can fill the varying gaps between supply from these sources, and normal energy use.  From the comments, it seems like I was not completely clear how intermittent and baseload power cause problems for each other, so I will start...

Active Power Inc (ACPW) announced an order from Eaton Powerware for twelve 500 kW DC flywheel systems. These units will ship in the first half of 2006 and be used to upgrade the power infrastructure of an existing data center in the United States.
