Alternative Energy Storage: Enabling the Smart Grid
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...
Investment Ideas From the One-House Grid
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...
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...
Hype Busters From Lux Research Explain Grid Based Energy Storage
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...
Grid-based Energy Storage: Widely Misunderstood Challenges and Opportunities
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...
The Electric Grid Index
Charles Morand A little while ago, we received the following request from a reader: " when are you going to start an ETF or mutual fund called "Energy TS&E". T for transmission, S for storage, and E for efficiency. I guess you need an index first. I'm thinking Quanta, Amer Superconductor, Exide, Axion, Itron, Echelon, etc. There is no good one stop shop for this subsector. Sign me up." While we don't plan on launching a licensable index or a mutual fund because of all the regulatory thicket we'd...
Comparing Electricity Storage and Transmission
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...
PowerSecure on a Solar Roll
by Debra Fiakas CFA Last week PowerSecure International (POWR: Nasdaq) announced the award of orders valued at $100 million for new solar projects. About 15% of the work will be completed in the final quarter of this year and the rest of the revenue will be recorded in 2016. The announcement sent investors into a tizzy. PowerSecure reported $283.4 million in total sales for the twelve months ending March 2015, primarily for solar power infrastructure and smart grid technology destined for electric utilities and microgrids. Securing orders equivalent to 35% of its current revenue run rate...
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...
How Are We Doing On Our Stimulus Plan Stocks So Far?
A few weeks ago, I wrote a series of two articles on the yet-to-be-unveiled Obama stimulus package for the economy, arguing that things pointed in the direction of massive infrastructure spending with a green twist. I argued that this would benefit a certain categories of rail-related stocks and electric grid stocks. How am I doing relative to the market as a whole, which has had several positive trading days for the past while on the back of the eventual stimulus plan? Railway Stocks I discussed four railway stocks in an article published on October 18....
Introducing PERGY
Impressed by the number of stocks in the Crystal Equity Research alternative energy indices that have delivered exceptional price appreciation, the last few posts have been on a quest to find fundamental characteristics that could give an advance signal of a future star. The post “Alternative Returns” on May 8th introduced the series identified future growth as a precursor of strong stock performance. The next post “Quest for Growth” on May 11th looked at stocks with above average growth predictions. Then the post “Alternative Bargains” looked at stocks in the alternative energy indices that are trading at below average price-earnings multiples.
There is a...
The War On Net Metering
by Paula Mints Net metering and interconnection are rights afforded distributed generation (DG) residential and commercial solar system owners through the U.S. Energy Policy Act of 2005. The act required publically owned utilities to offer net metering and left the various policies up to the states to enact. In 2004, before that energy policy was enacted, 39 states had net metering and interconnection standards and policies. At the beginning of 2016, 43 U.S. states and three territories had net metering policies, and four states had policies similar to net metering that the Database of State Incentives for Renewables...
Smart Grid’s Expected 250% 5-Yr Growth Rate is Great News for Cisco, IBM, Accenture,...
Bill Paul Lux Research forecast last week that the global smart grid market will grow some 250% over the next five years, reaching nearly $16 billion by 2015 compared with today’s $4.5 billion. Interestingly, Lux further forecast that only a few select firms will take full advantage of this looming largesse. It’s understandable why the payoff won’t be widely shared. As regulated entities (on the transmission and distribution side), electric utilities have an obligation (specifically, the time-honored “obligation to serve”) that effectively requires that they be conservative when partnering with IT firms that can provide the money-saving,...
The Best Peak Oil Investments Meet the Strong Grid: CVTech Group
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...
Comverge, Diverge, or Merge?
Tom Konrad CFA Comverge (COMV) has a great residential demand response business. The company lacks focus, but the stock has significant upside as an acquisition target. As part of my ongoing series on energy management companies (see these articles on World Energy Solutions (XWES) and EnerNOC (ENOC)) I spoke with Comverge CEO Blake Young. The Comverge Advantage Comverge is the strong leader in residential demand response (DR,) one of the most cost effective grid stability solutions. Even within demand response, residential DR is an excellent niche, because working in the market for residential DR...
2010: The Year of the Strong Grid? Part II
The Strongest Strong Grid Stocks Tom Konrad, CFA A comparison of the financial strength of transmission (or "Strong Grid") companies. In Part I of this article I made the case that transmission stocks, or "Strong Grid" might be a clean energy sector that takes off in 2010, as Smart Grid stocks and Battery stocks did in 2009. If the sector does take off, the rising tide will probably float all boats, but if it doesn't, it will probably be better to be in the strongest such companies, because, as in 2009, the harsh financial climate will probably mean that...
