Electric Grid

Research Analyst Bucks NaysayersBy Joyce Pellino CraneJay M. Meier may be out on a lonely limb, but the senior research analyst at Feltl and Company is unwavering in his enthusiasm for Digi International, Inc. (Nasdaq:DGII)Meier is recommending Digi as a buy, insisting that the company is undervalued given its potential for growth in the smart grid sector.“The company is woefully undervalued,” he said, “and it’s probably going to start growing in the second half of 2010 as evidenced by all the smart grid technology it has...”But other research analysts are not so sure. I spoke with two who...

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...

Tom Konrad, CFA If the Japanese use less nuclear power, what will take its place? I'm astounded by the resilience and discipline of the Japanese people in response to the three-pronged earthquake, tsunami, and nuclear disaster, perhaps in large part by my cultural roots in the egocentric United States, where we seem to have forgotten the virtue of self-sacrifice for the greater good.  Yet while Japanese society has shown itself to be particularly resilient, the Japanese electric grid is much less resilient.  According to International Energy Agency statistics, Japan produced 258 TWh of electricity from...

Part 2 of 2 Bill Paul Neither Daewoo Shipbuilding & Marine Engineering Co. Ltd., which trades OTC under the symbol DWOTF, nor Ener1 Inc., which trades on NASDAQ under the symbol HEV, is an obvious candidate for having hidden potential. Heck, Daewoo isn’t even a green energy stock. Or is it? Lost in the hubbub of Copenhagen and Congress, there’s been important news about both these companies that strongly suggests – at least to me – that each has plenty of undiscovered potential that will really start paying off over the next 18 to 24...

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...

Digi International’s Move toward Smart Grid Technology.Source: The Investor Relations Group, New York, NYApril 2005 - FS Forth-Systeme GmbH/Sistemas Embebidos S.A. (FS Forth), providers of embedded modules based on the company's processors and NET+OS software, as well as other microprocessors with supporting embedded software. May 2005 - acquired Rabbit Semiconductor® Inc. (formerly Z-World™, Inc.). The acquisition expanded Digi's embedded portfolio to include the Rabbit line of microprocessors and microprocessor-based core modules and Z-World single-board computers (now all sold under the Rabbit brand).

Part I: With Smart Grid Brains and Transmission Brawn... Tom Konrad, CFA A robust national grid will be essential to achieving high penetration for renewable electricity at reasonable cost, and the companies that can help build it are an essential part of a clean energy portfolio.   Many renewable energy advocates, especially those enchanted by the gigantic potential for solar, think that we can get by with local renewable energy.  While it's a pretty vision, the timing of wind and solar (the only forms of renewable energy that have the potential to produce 100% of our electricity) mean that this...

Microinverters are being used in smaller commercial solar installations, but the industry is in flux and coming regulations may drastically change the playing field.

by Tom Konrad CFA We cannot choose between transmission and renewable distributed electricity.  Local renewable generation requires long distance transmission to even out variations of supply.  Hence, both advocates of distributed renewables and large wind and solar farms should support transmission improvements.  Here are a few stocks which should benefit from such investments. Shortly after I launched Clean Energy Wonk, Blogger took the site down because I made the mistake of including both the words "Cheap" and "Free" in the title of an article about Energy Efficiency.  Since it can apparently take up to 2 months for a human...

Part 1 of 2 Bill Paul Looking for alternative energy stocks with undiscovered potential? Who isn't? Here are three possibilities (with three more to come next week). You can decide for yourself whether they are worth further investigation. First up: PFB Corporation, which trades on the Toronto Stock Exchange under the symbol PFB. Calgary-based PFB is an energy efficiency play. The company makes insulating building products that it sells under branded names in commercial and residential markets in North America and Japan. The company most recently reported third quarter net income of $1.6 million or 24 cents vs. $1.1...

by Elaine Thompson Bloomberg New Energy Finance, in an executive summary of its New Energy Outlook 2017 report, predicts renewable energy sources will represent almost three-quarters of the $10.2 trillion the world will invest in new power-generating technology. Analysts outline several reasons for this increase in spending, such as the decreasing costs of wind and solar and consumers’ increasing interest in solar panels. Competition between power sources also continues to grow, with products like utility-scale batteries upsetting coal and natural gas’s roles in the marketplace. But more importantly, state-driven renewable portfolio standards pave the way for additional ventures in renewable energy technologies, particularly...

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...

John Petersen On March 4, 2011 the Pacific Northwest National Laboratory published a comprehensive review of "Electrochemical Energy Storage Technologies for Green Grid" that is a must-read for serious investors who want to understand the technical and economic intricacies of the energy storage sector. It explains why storage is a key enabling technology for wind and solar power, the smart grid, efficient transportation and a legion of high-technology manufacturing and service enterprises that can't survive without reliable power. It also explains why energy storage is an investment mega-trend that will endure for decades. While I normally try to...

by Tom Konrad, Ph.D. Net metering is unfair and is dangerous for the long term health of utilities, at least according to Raymond Wuslich, when he spoke at the 2015 Renewable Energy Conference in Poughkeepsie, NY.  Wustlich is an attorney and partner at Winston & Strawn, LLP., and advises clients across the electricity and natural gas industries on Federal Energy Regulatory Commission (FERC) matters. To make his point, Wuslich used a simplified New York residential electric bill.  In this simplified bill, the customer was charged 12¢ per kWh for...
