Electric Grid

Companies taking steps towards the Smart Grid: Xcel Energy, Duke Energy, Whirlpool, Samsung Electronics, and Freescale Semiconductor.

The Casualty Last Monday, I discussed how I had recently reviewed Railpower Tech with a view to potentially adding to my position on grounds that: (a) the company had a fair amount of cash in the bank, which reduced the need to go to capital markets for financing for a while; and (b) that it was getting badly battered by general market conditions, potentially offering an attractive entry point. Although my portfolio has taken a beating in recent weeks, I remain ready to take small positions in stocks if I feel they are being unfairly bashed, including in...

By Harris Roen Knowing when to get in and out of a stock is critical to being a successful investor. This is especially true in the volatile alternative energy sector. The Roen Financial Report calculates a fair value range for each of the +/-250 alternative energy stocks that it tracks, so that investors can better understand a stocks relative value. Comparing the current stock price to the fair value range helps determine whether a stock is considered overvalued, undervalued, or at fair value. Which stocks are good prospects for the future, and where should investors proceed...

by Debra Fiakas CFA Electric power companies need plenty of generating plants and distribution works to bring electricity to our doors.  Electric utilities are very good at generating electricity and managing relationships with the families and businesses that use the power, but building all that infrastructure  -  drawing up plans, hauling in materials and fastening girders  -  is not necessarily a power company’s strong suit.  Enter Quanta, Inc. (PWR:  NYSE) with a full menu of design, engineering and construction services for electricity generation and distribution infrastructure. Solving problems for electric utilities is good business for Quanta.  The...

Ed Gunther From Solar Light Flashes: SPI12 Edition Sunny Boy TL-US Inverter SMA Solar Technology AG (ETR:S92) will begin limited shipments of the transformerless Sunny Boy 3000/4000/5000TL-US-22 inverter series for 3 to 5 kiloWatt rated AC power PV systems in 4Q12. The TL-US series has added a unique Emergency Power Supply feature providing daytime power to a dedicated power socket in the event of a grid power outage. The power socket is isolated from the grid during the outage and supplies up to 12 Amps so long as...

by Debra Fiakas CFA Solar power producers have many challenges.  One is the direct current to alternating current dilemma.  Solar panels create power that flows one way in a direct current (DC).  We use electricity in our homes and businesses in alternating current (AC) that flows both directions, forward and backward.  So solar cell producers must use solar inverters that convert the electricity from the direct current in the solar panel into alternating current. This is where Advanced Energy Industries, Inc. (AEIS:  Nasdaq) comes in. AEIS makes power inverters for the solar power industry.  The...

by Tom Konrad When I asked, Alternative Energy Stocks readers overwhelmingly wanted me to take another look at Composite Technology Corp. (OTC BB:CPTC.OB)  I've discussed CPTC several times over the last year, and consider it my most speculative pick in electricity transmission and distribution.  True to the nature of a speculative stock with no current earnings which is still trying to establish markets for its products, the stock price has been all over the map. The reader interest is doubtless due to the recent sharp decline since mid January.  I personally sold a portion of...

John Petersen Last week Debra Fiakas of Crystal Equity Research published an article titled "No Battery Producer Left Behind" that was based on old information about the relationship between Exide Technologies (XIDE) and Axion Power International (AXPW) and reached several erroneous conclusions. Since I'm a former Axion director, the stock is my biggest holding and I follow the company like a hawk, Tom Konrad asked me to clarify the record and present a high level overview of Axion's business history, stock market dynamics and technical accomplishments over the last four years. Since Tom's request is a...

John Petersen Last week I appeared as a luncheon speaker at EESAT 2009, a biennial international technical conference sponsored by the DOE, Sandia National Laboratories and the Electricity Storage Association that focuses on storage technologies for utility applications. The conference included dozens of high-level technical presentations from storage technology developers and was far and away the best-organized event I've ever attended. The only notable absence was a large contingent of buyers, which left some participants wondering whether they were preaching to the choir. Nevertheless, I was encouraged by rapid growth in the number and size of utility-scale demonstration...

My five favorite stocks with technology to improve grid reliability. Tom Konrad, Ph.D., CFA Although the market has risen above where it was in early June, when I said "We're near the top," I'm still bearish.  And I'm still making lists of stocks to buy when prices seem more favorable.  Previous articles in this Clean Energy Stocks Shopping List series are listed at the end of this one. The Strong Grid I recently wrote about our list of Smart Grid Stocks, and at least two readers were prompted to ask why wasn't (1) Beacon Power (BCON) on the...

Paul Denholm, a Senior Analyst at the National Renewable Energy Lab (NREL), sees an upcoming struggle between renewable sources of electricity such as photovoltaics (PV) and wind with low-carbon baseload alternatives for space on the low carbon grid of the future.  These baseload alternatives are nuclear and Internal Gasification Combined Cycle coal plants with Carbon Capture and Sequestration (IGCC w/ CCS, refereed to by advocates as "Clean Coal). This may come as a shock to advocates of the idea that Global Warming is such a big problem that we will need all forms of low carbon electricity, because the...

Tom Konrad, CFA With all the discussion of grid based energy storage for renewable energy integration, the two cheapest and most mature solutions are overlooked.  They are also the solutions most often overlooked by investors captivated by the story of clean technology. A few years ago, I put together some graphs to show this as dramatically as possible.  I surveyed the available data on energy storage and other grid integration technologies for the costs of existing installations, and calculated average cost per installed kW (power), per installed kWh (energy) and round trip efficiency (the percent of energy...

Tom Konrad, CFA Colorado's recently released Renewable Energy Development Infrastructure (REDI) report looks at what the resource-rich state needs to do to accomplish the state goal of reducing CO2 emissions 20% from 2005 levels by 2020.  Investors who expect the developed world to attempt similar cuts in emissions should take note of the report's conclusions, and invest accordingly. Since Colorado Governor Bill Ritter recruited my friend Morey Wolfson for the Colorado Governor's Energy Office (GEO) he's had a lot less time to socialize with the rest of us in the clean energy community, but we caught up over lunch...

Tom Konrad What will the New Year hold for Clean Energy?   For the people who manage clean energy portfolios, mutual funds, and indexes the question is more than idle curiosity.  Getting the answer right means finding the stocks which will put a shine on your solar portfolio’s returns.  Getting it wrong means the competition will blow away your wind stocks. I asked my network of green money managers for their predictions.  This is the second in a series on their predictions and stock picks from my panel.  This first article focused on what they had to...

David Gold Grants for smart grid projects. Grants for battery manufacturing lines. Loan guarantees for renewable energy project development. Grants to private companies for energy efficiency projects. And with each it seems that the cleantech world cheers. Yet for all our desire to create sustainability in our consumption and use of energy, this model of getting us there is not only unsustainable but is of questionable value. I want to emphasize that I am speaking about government grants to the private sector where the government is not the end customer and...

John Petersen The electric power system in the U.S. is dirty, antiquated, stupid, unstable, and a security nightmare. After years of discussion and debate, consensus now holds that the generation, transmission and distribution infrastructure will need hundreds of billions in new investment to reduce emissions, improve reliability, minimize waste and inefficiency, improve security, and facilitate the integration of wind, solar and other emerging alternative energy technologies. Commonly cited capital spending estimates range from $200 billion globally by 2015 to $2 trillion overall. In his November 2008 report, "The Sixth Industrial Revolution: The Coming of Cleantech," Merrill Lynch strategist...
