Digi International Positioned for Growthby Joyce Pellino CraneCaught between a maturing sector and a nascent one, Digi International, Inc., (Nasdaq:DGII) is stirring opposition among research analysts, who view its recent acquisitions as either a brazen entry into an emerging area, or a compensatory cover for poor performance.Over the past five years, the company has ventured into the smart grid sector through several acquisitions of wireless and cellular technology companies. One industry observer, who did not want to be quoted, said acquisitions artificially increase revenues during a down economy.  Another, who asked not to be identified, said the Digi...

Last week, Charles told us to expect wind power industry suppliers to benefit from shortages in wind turbine components. Owens Corning (NYSE:OC) which I mentioned in my Blue Chip Alternative Energy Portfolio fits nicely into this category with their composites for turbine blades, as do the power converter stocks I mentioned two weeks ago. As essential to wind power as any of these is improved power transmission. The National Wind Coordinating Collaborative states, Electrical transmission facilities connecting windy areas and load centers are sometimes non-existent or minimal. Even in cases where a good wind resource has...

by Debra Fiakas CFA Everybody likes a bargain.  Investors really like a good cheap buy.  A review of our four alternative energy industries revealed three stocks trading below industry average multiples of forecasted earnings. This is the final article in the series, the first looked at Ormat (ORA:NYSE), and the second looked at Kadant (KAI:NYSE).    The first week in November 2014, could have been a turning point for trading in shares of Advanced Energy Industries, Inc. (AEIS:  Nasdaq).  The company reported flat sales in the quarter ending September 2014, compared to the same quarter last...

by Debra Fiakas CFA My recent post “Bull Case in Rick Perry’s Grid Study” highlighted efforts by U.S. Energy Secretary Rick Perry to help the coal industry with a study of the U.S. electrical grid.  Coal has long claimed advantage as a ‘dispatchable’ power source, i.e. a consistently available power source suitable to supply power for the base load.  Technology is making base load less important.  Indeed, modernized or ‘smart’ electrical grids are making it possible to take advantage of low-cost renewable power sources even though they produce power intermittently and are therefore considered ‘not dispatchable’. ...

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...

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...

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

by Joeseph McCabe, P.E. Which vendors at Intersolar 2016 in San Francisco supply the best behind the meter self generation microgrid solutions?  I’ve asked similar questions about utility owned inverters, storage, and microgrids at previous Intersolars. This year I looked into the microgrid highest value propositions for photovoltaics (PV). What is a microgrid, and why they are coming of age now? A microgrid is a distinct electric system consisting of distributed energy resources which can include demand management, storage and generation.  Loads are capable of operating in parallel with, or independently from, the...

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...

Electricity Storage and Transmission are naturally complementary, and more of both will be needed.  But given limited time and resources, where should those of us who want to see as much renewable electricity on the grid as soon as possible concentrate our efforts?  The choice is not immediately clear. Dennis Ray, ED of Power Systems Engineering Research Center (PSERC) was quoted as saying “Regardless of contractual arrangements that are subject to environmental regulation, the ultimate dispatch pattern that will determine the actual emissions is largely dependent on transmission constraints and reliability considerations.” Horses for Courses At a basic...

Value Investing A few months ago, I discussed my encounter with Warren Buffett, and promised that I would eventually analyze a stock using the value investing (VI) approach. While I can`t say that I qualify as a hardcore value investor, there are many things about the VI approach that have influenced my thinking. For instance, I tend to stay away from very high PE stocks and momentum plays. While I take positions in firms with no earnings, they are generally relatively "unknown" or are past star stocks that investors have moved on from. I like the idea...

Paul Schwabe Among renewable resources, one of the most valuable attributes of geothermal electricity is the baseload characteristic of the energy resource. That is, geothermal electricity generators are able to deliver a stable level of power production over time. Yet for better or worse, this baseload characteristicalong with other notable factors such as size constraints and varying market segmentsreveals that interconnecting a geothermal plant to a transmission or distribution system poses unique challenges compared to other renewable energy technologies . A recent report by NREL, "Geothermal Power and Interconnection: The Economics of Getting to the Market," delves...

Equus Total Return (NYSE: EQS) is a closed-end fund that trades at a 42% discount to its net asset value (NAV). The fund invests primarily in both debt and equity instruments of small-caps and private companies. Each quarter, management must report the fair value of its net assets, but the stock market value of Equus is much lower than that of its net assets. Here's a chart showing Equus' discount to its net assets for the last five years: As we can see, Equus is used to trading at a discount to its NAV, but...

I'm not sure whether John Maynard Keynes, the father of Keynesian economics and an ardent proponent of government interventionism during hard economic times, and Rachel Carson, the mother of modern environmentalism and the author whose work is credited for the eventual creation of the EPA, ever met during their lifetimes. But if current voter sentiment holds until November 4, their ideas could soon converge and form the basis of government policy for at least the next four years. Let me explain. First, John Maynard Keynes. There is no doubt that the deliberate and coordinated nationalization of financial services...

Diamond in the Rough Alternative energy stocks are usually exciting, development stage companies with break-through technology which just might to totally transform the way we live.  Unfortunately, that's a better description of a speculative lottery ticket style company than a solid investment which will provide solid, long-term capital gains.  So it's always a pleasure to find a company whose products are so commonplace that we don't even notice them, even when we see them every day, and yet is involved in essential work to reduce our dependence on fossil fuels.  I took this picture in...
