Powering Advanced Energy
by Debra Fiakas CFA Solar power producers have many challenges. One is the direct current to alternating current dilemma. Solar panels create power that flows one way in a direct current (DC). We use electricity in our homes and businesses in alternating current (AC) that flows both directions, forward and backward. So solar cell producers must use solar inverters that convert the electricity from the direct current in the solar panel into alternating current. This is where Advanced Energy Industries, Inc. (AEIS: Nasdaq) comes in. AEIS makes power inverters for the solar power industry. The...
ABB: Improving Transmission and Distribution Efficiency
Diamond in the Rough Alternative energy stocks are usually exciting, development stage companies with break-through technology which just might to totally transform the way we live. Unfortunately, that's a better description of a speculative lottery ticket style company than a solid investment which will provide solid, long-term capital gains. So it's always a pleasure to find a company whose products are so commonplace that we don't even notice them, even when we see them every day, and yet is involved in essential work to reduce our dependence on fossil fuels. I took this picture in...
Microgrids: The Electric BTM Line
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...
Transmission Stocks: Bringing Wind Power to Where it’s Needed
Last week, Charles told us to expect wind power industry suppliers to benefit from shortages in wind turbine components. Owens Corning (NYSE:OC) which I mentioned in my Blue Chip Alternative Energy Portfolio fits nicely into this category with their composites for turbine blades, as do the power converter stocks I mentioned two weeks ago. As essential to wind power as any of these is improved power transmission. The National Wind Coordinating Collaborative states, Electrical transmission facilities connecting windy areas and load centers are sometimes non-existent or minimal. Even in cases where a good wind resource has...
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...
2010: The Year of the Strong Grid?
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...
Wind and Heat Pumps: A Winning Combination
This article has been cross-posted on The Oil Drum. Last month, I brought you some nice maps showing when and where good wind resources are found in the US. Now I've found something better: a visual comparison of electrical load with wind farm production, published by the Western Area Power Administration in 2006. The study compared electricity production from five wind farms in Northern Colorado, Southwestern Nebraska, and Central Wyoming in 2004, 2005, and the start of 2006, compared with electricity consumption in the same area over the same time period. Comparison of Wind Production to...
Will Surging Smart Grid Investments Result in Surging Electric Prices?
John Petersen The electric power system in the U.S. is dirty, antiquated, stupid, unstable, and a security nightmare. After years of discussion and debate, consensus now holds that the generation, transmission and distribution infrastructure will need hundreds of billions in new investment to reduce emissions, improve reliability, minimize waste and inefficiency, improve security, and facilitate the integration of wind, solar and other emerging alternative energy technologies. Commonly cited capital spending estimates range from $200 billion globally by 2015 to $2 trillion overall. In his November 2008 report, "The Sixth Industrial Revolution: The Coming of Cleantech," Merrill Lynch strategist...

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...
Geothermal Transmission 101
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...
The Best Peak Oil Investments Meet the Smart Grid: Telvent GIT SA (TLVT)
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...

Feel-Good Government Grants Leading Cleantech Astray
David Gold Grants for smart grid projects. Grants for battery manufacturing lines. Loan guarantees for renewable energy project development. Grants to private companies for energy efficiency projects. And with each it seems that the cleantech world cheers. Yet for all our desire to create sustainability in our consumption and use of energy, this model of getting us there is not only unsustainable but is of questionable value. I want to emphasize that I am speaking about government grants to the private sector where the government is not the end customer and...
Tribulations of a Meter Reader
by Debra Fiakas CFA Last week Badger Meter (BMI: NYSE) joined a building fraternity: companies reporting strong year-over-year sales growth, but delivering weaker than expected earnings. However, the Badger Meter actually increased earnings by a greater magnitude than it grew sales. The Company reported $83.5 million in net sales, representing 16.3% growth over the same quarter last year. Net income grew by 59.3% year-over-year to $4.6 million or $0.32 per share. As impressive as these results appear to be, the consensus had been for earnings per share of $0.41. The stock declined sharply as investor registered their displeasure...
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,...
