Storage: The Best Renewable Energy Integration Strategy?

Tom Konrad, Ph.D. In order to electrify transportation, well need batteries, with ultracapacitors and compressed air playing supporting roles.  Based on cost, John has been making the case that the batteries for economical cars are more likely to be advanced lead-acid (PbA) than the media darling, Lithium-ion (Li-ion.)  I generally agree, especially since recycling Li-ion batteries is an expensive and difficult process, although I see a future where both cars and oil are simply more expensive, and we have far fewer of them. But transportation is only one application for energy storage...

Bold or Bogus? Digi International’s Move toward Smart Grid Technology

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...
demand charge impacts on DC Fast Charger costs

EV Fast Charging Disincentives

by Daryl Roberts DC Fast Chargers (DCFCs) and Tesla superchargers are a key element in electric vehicle (EV) charging infrastructure that could facilitate wider adoption of EVs by enabling recharging that comes to resemble the time currently taken for gas station stops, and thereby reducing “range anxiety” for drivers. However, the pricing structure for electrical costs incurred at commercial DC fast chargers is currently prohibitive, because it includes a special fee called a “demand charge”. Rate design in a number of states includes this additional charge, based on the “peak rate” on electric power consumed in kW. In New York,...

Playing the ‘Global Grid Game’ – Japan’s NGK, GE Majority-Owned Indo Tech Look Strong

Maintaining and expanding the world's electric power grids in order to avoid stupendous blackouts, add gigawatts of green power, and bring electricity to a billion additional people, will cost hundreds of billions of dollars over the next 10 years. Retrofitting just the U.S. power grid will cost $130 billion, estimates the Electric Power Research Institute (EPRI). China has earmarked $135 billion to upgrade and expand its high-voltage grid. India will need to spend billions if it has any hope of reaching its goal of increasing electrical generation capacity to 200 GW by 2012 from roughly 150 GW currently. Among...

Axion Power – A Battery Manufacturer Charging Forward

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...

2010: The Year of the Strong Grid? Part VI: Will the Real Strong Grid...

Tom Konrad, CFA For clean electricity to flourish, the electric grid needs not only to be smarter, but more robust.  This is where my strong grid stocks come in.  But stringing wires for power is a lot like stringing wires for telecommunications as well a large number of other businesses which do not have much to do with the energy trends I hope will boost the long term prospect of these companies.  Knowing how much these companies earn from grid infrastructure helps predict how much they will benefit from the trend. Unlike many of the financial statistics...

Our Smart Grid Stock List

Tom Konrad, Ph.D., CFA I've been writing about the smart grid and its potential since before I joined AltEnergyStocks, in 2007, although at the time, I wasn't using the term: I mostly called it "Smart Metering."  Now, Smart Grid is a central part of federal stimulus plans, and the term is firmly ensconced in the popular lexicon.  GE even created a Super Bowl ad around the Smart Grid (video). It was far past time to create a Smart Grid category in our Alternative Energy Stock List, but now we've done it.  The companies in the Smart Grid Stock List...

Hidden Gems? Why Green Investors Should Look at Daewoo Shipbuilding and Ener1

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...

Strong Grid Stocks Getting Stronger

Will 2012 Finally be the Year of the Strong Grid? Tom Konrad CFA Utility infrastructure companies are seeing the beginnings of the long-anticipated infrastructure boom, and have the rising revenues and backlog to prove it. Investing in electric utility infrastructure has long been one of my favored ways to invest in the growing renewable energy sector without having to take a bet on unproven technology.  The North American grid is in badly in need of an upgrade, and increasing penetration of variable and distributed resources such as solar and wind will require further upgrades in order to...

Smart Grid Sector Gaining Traction from Stimulus Funds

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...

Advanced Energy: Overlooked and Undervalued

Investors interested in renewable energy often get singularly focused on innovators new energy sources at the expense of companies that provide the nuts and bolts of the energy infrastructure.  Advanced Energy Industries (AEIS:  Nasdaq) is a stalwart of the electric power network, providing power conversion and control components that convert energy to the proper current for use by consumers and business.  The company has a broad product line that has applications with a diverse customer base, including semiconductor manufacturers and chemical processing plants. The 2017 acquisition of Excelsys Holdings Ltd. based in Ireland added products targeted at medical and industrial applications. As popular as Advanced...

Hither and Yon: Transmission and Biofuels

In the most recent two installments of Energy Tech Stocks' interview with me cover my views on transmission stocks, and biofuel stocks.  Readers of AltEnergyStocks know that I am a big fan of electricity transmission, a theme I keep coming back to.  You also know that I have a very ambivalent relationship with both ethanol and biodiesel.  So I liked Bill's transmission article, but I just wasn't able to convey to him the subtleties of how I feel about biofuels.  But he got one thing right: the owners of biofuel feedstock are likely going to be the biggest winners....

Demand Planning: The Future of Demand Side Management

Electric utilities have a process by which they project future expected demand for electricity, and then find resources, either new electric generation or energy efficiency (Demand Side Management, or DSM) resources to meet that expected demand, or reduce that demand.  Progressive utilities and utility regulators now include DSM among the mix of resources as a matter of course.  According to Martin Kushler, of the American Council for an Energy Efficient Economy (ACEEE) who spoke at the Southwest Regional Energy Efficiency Workshop about an upcoming report from ACEEE, DSM resources cost an average of 3 cents per kWh of energy...

Clean Energy Stocks to Fill the Nuclear Gap

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...

Democratizing the Grid

by Daryl Roberts In a previous article I investigated the question of whether private sector capital was being stimulated sufficiently enough to build out renewable infrastructure on pace to reach climate goals.  I found that on the upper end, giant institutional funds were only mobilizing a tiny fraction of their total Assets Under Management, due to regulatory constraints and uncompetitive yields.  On the lower end, smaller scale funding seemed to be growing, with facilitation from intermediaries, fintech aggregation services, and increased access at lower levels to complicated derisking strategies. But I now find reporting that capital is over-mobilized, that solar may...

Welcome To The New World

Perhaps ironically, it took one of the worst financial and economic crises of the past three decades to bring "the grid" into investor focus. To be sure, certain alt energy aficionados such as Tom have been on this topic for a long time (Tom is actually the one who introduced me to the grid as an investment theme). However, it is fair to say that most investors, including alt energy investors, have not historically paid the grid a huge deal of attention. That is because most people outside of alt energy and VC circles held, until recently, the Old...
