Drawing the Right Lessons from the Texas "Wind" Emergency

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...

Clean Energy Stocks Shopping List: Smart Grid and Strong Grid

My five favorite stocks with technology to improve grid reliability. Tom Konrad, Ph.D., CFA Although the market has risen above where it was in early June, when I said "We're near the top," I'm still bearish.  And I'm still making lists of stocks to buy when prices seem more favorable.  Previous articles in this Clean Energy Stocks Shopping List series are listed at the end of this one. The Strong Grid I recently wrote about our list of Smart Grid Stocks, and at least two readers were prompted to ask why wasn't (1) Beacon Power (BCON) on the...

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...

A Profitable Smart Grid Penny Stock Aims for a NASDAQ Listing

Tom Konrad CFA A NASDAQ listing could bring a quick profit to investors who buy now, but beware the business risk. Ambient Corp. (ABTG.OB) offers an Internet Protocol (IP) smart grid communications platform to electric utilities.  So far, they have exactly one customer: Duke Energy (DUK).  Duke selected Ambient's X-series communication node solution, which flexibly gathers data from multiple smart meters and relays it to the utility.  For instance, in some cases Duke is using Ambient's nodes to gather data from both Echelon Corporation's (ELON) smart meters using data over powerline technology, and Badger Meter's (BMI) smart...

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...

Discom-fort: Barriers to Renewables in India

by Ishaan Goel Energy is crucial to India’s policy agenda. Millions of households are yet to gain reliable access to electricity, hampering their potential for economic growth. Severe pollution issues create widespread health problems. Renewables are prioritized as viable solutions across the political spectrum, with their low costs and ease of installation in remote regions. The current administration has ambitious plans for renewable energy (RE), targeting an almost 4x increase in installed capacity to 450 GW by 2030 and introducing a spate of tax and investment reforms. At the heart of the Indian power supply chain lie distribution companies (discoms). The...

Fending Cyber Threats with a Fortress

RuggedCom Fortifies the Smart Grid and Captures the Substation Market By Joyce Pellino Crane     I wonder how many utility executives lie awake at night worrying  about cyberthreats to their electricity substations.     If you’ve ever gone a few days without electricity in your home,  you’ll quickly realize how minimal life becomes.  Working on your computerthe speedway to higher thinking and creativity is impossible.     Watching television, charging your cell phone, keeping food frozen, and  micro-waving popcorn, can no longer be done. Every task requires  planning and, much more physical laborconsider what it would take  to wash and...

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...

The Sector Information Technology Forgot

Tom Konrad CFA Information technology has mostly passed the energy sector by... but for how long? Information Technology revolutionized the way we buy things (Amazon, eBay), how we get information (Google, Wikipedia, the decline of newspapers), and how we interact with out peers (Facebook, Twitter, LinkedIn.)  Yet so far, it has had little, if any transformative impact on energy.  Tim Healy, CEO of EnerNOC (ENOC), the world's largest  third party provider of Demand Response to utilities and grid operators, thinks that's about to change. Demand Response (DR) began decades ago with Interruptible loads and Interruptible rates,...

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...

Climate Change & Corporate Disclosure: Should Investors Care?

Charles Morand On Monday morning, I received an e-copy of a new research note by BofA Merrill Lynch arguing that disclosure by publicly-listed companies on the issue of climate change was becoming increasingly "important". The note claimed: "e believe smart investors and companies will recognize the edge they can gain by understanding low carbon trends." I couldn't agree more with that statement. It was no coincidence that on that same day the Carbon Disclosure Project (CDP), a non-profit UK-based organization that surveys public companies each year on the state of their climate change awareness, was...

Hammond Power Solutions: A Cheap Power Regulation Play?

We have discussed on several occasions the investment opportunities related to power regulation and renewable energy. I have also recently written about the value approach to investing. I came across a stock today that I believed fell into both categories: power regulation (transformers) and value. The stock is Hammond Power Solutions (HPS-A.TO or HMDPF.PK), a firm that makes transformers for a number of applications, including wind turbines. While revenue and earnings have been ramping up quite nicely over the past four years, the stock price has been trending mostly laterally (albeit in a volatile manner) over the...

Tres Amigas Proposes Three-way Transmission Link

by Michael Giberson If completed, the Tres Amigas project will encourage renewable power development and efficient power flows.  Publicly traded wind power and superconducting cable company American Superconductor Corp. (Nasdaq: AMSC) is a large minority shareholder and the planned supplier. Tres Amigas LLC has proposed building a three-way superconducting HVDC link between the three separate power systems that span the United States and much of Canada: the Eastern Interconnection, the Western Interconnection, and the Texas (ERCOT) Interconnection.  The three systems currently are linked by a small number of separate and relatively unimportant DC interties.  The proposed three-way...
