Electric Grid

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...

Tom Konrad CFA I'm bullish on Smart Transportation, which is my term for applying information technology to make our transportation system more efficient.  The majority of my list of Smart Transportation Stocks focus on GPS navigation.  I've been a fan of GPS navigation ever since 2001, when I first experienced the relief using one while driving in an unfamiliar city.  But I'm much less enthusiastic about GPS Navigation stocks: I feel the industry is too competitive, which is great for the consumer, but not so great for the shareholder.  Hence, I'm drawn to the three Smart...

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...

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’. ...

by Joe McCabe Where is the money in microgrids? My goal at this years Intersolar event was to try and answer this question; to figure out the value proposition of microgrids as they relate to distributed generation, storage, renewable energy and photovoltaics.  A microgrid is an electrical supply and use system that can operate autonomously. Although all microgrids are small relative to the electric grid as a whole, the huge size of the grid leaves a broad range of what can count as “micro.”  Microgrids can be as small as a single building, but range on...

Demand Responder Eyes New Growth Areas as Key Market Prices Dip  by Joyce Pellino CraneEnerNOC, Inc., announced its acquisition of Cogent Energy, Inc., on December 9, signaling a strategic move into the energy efficiency sector that is designed to help it capitalize on the Smart Grid’s growth potential.But the company was launched in 2004 as one solution to the country’s burgeoning demand for energy, and has grown into a leader among a handful of competitors in the demand response market.  Boston-based EnerNOC (Nasdaq: ENOC) helps businesses and grid operators reduce electricity consumption when demand is peaking and capacity strained. The...

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...

James Montgomery A pair of analyst reports issued last week came to roughly the same conclusion about the market for solar PV inverters: It's getting crowded and complicated, with top incumbents facing challenges in maintaining near-term growth in an increasingly fragmented market. Those PV inverter stalwarts will need to pursue more restructuring and mergers & acquisitions to stay atop the shifting and broadening customer base, addressing everything from tough-to-crack markets (e.g. China, Japan) and embracing newer technologies such as module-level power conversion, i.e. microinverters, say IMS Research and GTM Research. This consolidation has already started to play...

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...

In June, I wrote how intermittent power sources such as photovoltaics and wind would have to compete with baseload technologies such as IGCC "Clean Coal" and nuclear for capacity on the grid.  The key problem is that neither baseload technologies nor intermittent technologies are able to match themselves to the fluctuations of demand.  This creates a need for technologies which can fill the varying gaps between supply from these sources, and normal energy use.  From the comments, it seems like I was not completely clear how intermittent and baseload power cause problems for each other, so I will start...

John Petersen In 1883 Thomas Edison said, "The storage battery is one of those peculiar things which appeals to the imagination, and no more perfect thing could be desired by stock swindlers than that very selfsame thing. ... Just as soon as a man gets working on the secondary battery it brings out his latent capacity for lying." The problem isn't so much the batteries, which haven't improved all that much over the last century. Instead, the problem lies in the fertile imaginations of scientists, engineers, politicians, ideologues, analysts and investors who focus on new energy...

Net metering describes the requirement that an electric utility buy electricity from any of its customers that generate their own electricity (usually with some sort of renewable energy, such as solar or wind) at the same price that they sell it to the customer.  That seems fair, doesn't it? The Utility Perspective It doesn't seem fair to the utility.  Utilities do more than just generate and sell electricity to customers.  They also are responsible for transmission (delivering the electricity) and reliability (making sure that the lights work when you flip the switch.) Taking just the reliability requirement, suppose that...

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...

By Harris Roen An important part of the smart grid will be devices that connect the user to the grid, or “reading points”. These reading points go way beyond the current meter reading system that just monitor the amount of energy used. The long held belief that meter reading was the only way to monitor household and business’s consumption is quickly being replaced with alternate ideas.   MasTec (MTZ) is a contracting firm with $2.1 billion in annual sales focused on utility and communications infrastructure. It specializes in communications, high-speed Internet and electric distribution, as well as...

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...

Tom Konrad CFA CVTech Group (CVT.TO, CVTPF.PK) operates in two of my favorite clean energy sectors: electricity transmission and distribution and efficient vehicles.  Here is a look at the company's fundamentals. In "The Strongest Strong Grid Stocks" of my 2010: The Year of the Strong Grid? series, I took a quick look at CVTech Group's financial ratios, and decided not to look deeper because they had considerably more debt in comparison to income than the other electricity transmission ("strong grid") stocks I covered in that article.  I came across CVTech again while looking at companies involved in...
