Electric Grid

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...

A look at Itron, Echelon, Woodward Governor, EnerNOC, and Energy Recovery

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...

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...

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...

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...

Tildy Bayar A microinverter from iEnergy Photovoltaic (PV) microinverters, traditionally used in smaller rooftop solar installations, are being used in a 2.3-MW commercial rooftop installation in Ontario, Canada, supplier Enphase Energy (ENPH) has announced. The installation is the largest commercial rooftop project under the province’s feed-in tariff (FiT). Analysis firm IHS Research has called the announcement a milestone in the microinverter segment’s progress towards establishing itself outside its biggest market, the U.S., and outside the residential solar segment.  According to IHS’s analysis, PV microinverter shipments are forecast to exceed...

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

This article is a continuation of my Ten Alternative Energy Speculations for 2008, with picks #8, 9, and10 published last Thursday.  If you haven't already, please read the introduction of that article before buying any of the stock picks that follow.  These companies are likely to be highly volatile, and large positions are not appropriate for many investors.   My least risky picks (#8,9, and #10) are part of that same article; my most speculative plays (#1-3) will are here. #7 Electro Energy, Inc. (NasdaqCM:EEEI) $0.68 Electro Energy has risen 36% in the month and a half since I last...

John Petersen The most widely misunderstood subject in the field of energy storage is the potential for grid-based applications. They fire the imagination because the grid is so pervasive and the need is so great. They also present immense challenges to storage technology developers because the fundamental economic value per unit of grid-based energy storage is very low. While the subject of grid-based storage provides rich fodder for media reports and political posturing, the reality bears little relation to the perception. On March 9th, Lux Research published a sorely needed reality check in a new report titled "Grid...

Like Quanta Services, (#8 in this series), National Grid PLC (NYSE:NGG) allows investors to participate in the massive build out of electricity transmission and distribution infrastructure necessitated by years of neglect and the growing need to decarbonize our electric infrastructure.  See the article linked above for more detail on these two forces driving the sector. Having its origins in British electricity deregulation in the 1990s, Nation Grid is a regulated utility in Britain and the United States, and operates high pressure gas pipelines and high voltage transmission in Britain, and electricity transmission and natural gas distribution in the Northeastern...

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...

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...

On February 26, 2008, a drop in wind generation by about 1400 MW over ten minutes, coupled with an increase in demand of 4412 MW due to colder weather, and lower-than scheduled production from other power suppliers, led ERCOT, the Texas grid operator to cut 1100 MW of power to interruptible customers for about 90 minutes.   Misconceptions All these facts come from a Reuters article misleadingly titled "Loss of wind causes Texas power grid emergency."  I was dismayed a few weeks ago when this misleading reporting led the generally insightful Master Resource Report to conclude "This is a clear...

Shoppers who bring reusable bags to the grocery store buy more junk food. This example is part of a growing body of behavioral psychology research showing that when we feel good about ourselves for doing one thing right, we give ourselves permission to be careless in other areas. The solar installation industry seems to be falling into the "reusable shopping bag" trap. Solar itself is the reusable shopping bag. The junk food is net metering. Net metering is a simple, intuitive way to pay for solar generation at retail rates. But it puts solar companies on...
