Transmission – The Bottleneck We All Saw Coming
by Paula Mints
Transmission and distribution is the process of getting electricity from the point of generation to the point of use. Unfortunately, upgrades, maintenance, and the need to extend the electricity infrastructure from point a to point b are often ignored. Also ignored are infrastructure designs that support a distributed grid with renewable energy sources of electricity.
Transmission bottlenecks are the utterly foreseeable consequence of accelerated solar and
wind deployment. As countries worldwide were announcing RE goals, holding auctions, and providing incentives, system operators everywhere were warning about the need to add new and upgrade existing infrastructure while also warning about...
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...

10 Clean Energy Stocks for 2021: Diversification
by Tom Konrad, Ph.D., CFA
Rounding out the discussion of the stocks in my 10 Clean Energy Stocks for 2021 list are the two that don’t fit either of the themes I highlighted for 2021: Picks and Shovels or a Possible Yieldco Boom. Both help with diversification, both in terms of their industry and geography.
MiX Telematics (MIXT) was retained from the Ten Clean Energy Stocks for 2020 list because I expect its prospects to improve rapidly as the world comes out of covid lockdowns. The global vehicle telematics provider has a large number of its customers among mass transit, logistics,...
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...
Energy Storage as Transmission Explained
by Blackridge Research
The latest trend is that power transmission companies around the world are increasingly looking at energy storage technology to defer or replace transmission system upgrades. How this works is energy storage is placed along a transmission line and operated to inject or absorb power, mimicking transmission line flows. Going with names like “virtual transmission” in Australia and “GridBooster” in Germany, projects totaling over 3 GW of capacity are poised to increase system efficiency and reliability across the world.
Storage as transmission offers an array of benefits over traditional transmission infrastructure. They are faster to deploy, have smaller footprint,...
Digital Electrification: Less Waste, More Capacity
One potentially huge contributor to decarbonization of the economy could come from dramatic efficiency gains obtainable from digitally improving the power quality of electricity, as it is being generated, transmitted & being consumed. The enabling technology is emerging from developments in computing that is associated with the Internet of Things (IOT).
DOE estimates indicate that approximately 38.2 quads of electricity are produced, from all sources, but that 25.3 quads, or 66.2% is deemed “Rejected Energy”, so only 33.8% of generated electricity is actually being used. Within that 66% a distinction is recognized between “Losses” & “Waste”:
Loss is non-recoverable, I2R...
EV Fast Charging Disincentives
by Daryl Roberts
DC Fast Chargers (DCFCs) and Tesla superchargers are a key element in electric vehicle (EV) charging infrastructure that could facilitate wider adoption of EVs by enabling recharging that comes to resemble the time currently taken for gas station stops, and thereby reducing “range anxiety” for drivers.
However, the pricing structure for electrical costs incurred at commercial DC fast chargers is currently prohibitive, because it includes a special fee called a “demand charge”. Rate design in a number of states includes this additional charge, based on the “peak rate” on electric power consumed in kW. In New York,...
Bold or Bogus? Digi International’s Move toward Smart Grid Technology
Research Analyst Bucks NaysayersBy Joyce Pellino CraneJay M. Meier may be out on a lonely limb, but the senior research analyst at Feltl and Company is unwavering in his enthusiasm for Digi International, Inc. (Nasdaq:DGII)Meier is recommending Digi as a buy, insisting that the company is undervalued given its potential for growth in the smart grid sector.“The company is woefully undervalued,” he said, “and it’s probably going to start growing in the second half of 2010 as evidenced by all the smart grid technology it has...”But other research analysts are not so sure. I spoke with two who...
The Case For Transmission, and Transmission Stock List
by Tom Konrad CFA We cannot choose between transmission and renewable distributed electricity. Local renewable generation requires long distance transmission to even out variations of supply. Hence, both advocates of distributed renewables and large wind and solar farms should support transmission improvements. Here are a few stocks which should benefit from such investments. Shortly after I launched Clean Energy Wonk, Blogger took the site down because I made the mistake of including both the words "Cheap" and "Free" in the title of an article about Energy Efficiency. Since it can apparently take up to 2 months for a human...
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...
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...
How Energy Deregulation Affects States and Stocks
by Elaine Thompson
Bloomberg New Energy Finance, in an executive summary of its New Energy Outlook 2017 report, predicts renewable energy sources will represent almost three-quarters of the $10.2 trillion the world will invest in new power-generating technology.
Analysts outline several reasons for this increase in spending, such as the decreasing costs of wind and solar and consumers’ increasing interest in solar panels. Competition between power sources also continues to grow, with products like utility-scale batteries upsetting coal and natural gas’s roles in the marketplace.
But more importantly, state-driven renewable portfolio standards pave the way for additional ventures in renewable energy technologies, particularly...
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...
