Capacity Market Poker

By Energy Rant No Comments
About two weeks ago, New England got a punch in the mouth from old man winter. I tuned into the Mt. Washington Observatory (New Hampshire) to check the conditions. On Friday evening, February 3, it was cool and breezy at minus 46°F with 99 mph wind and freezing fog. I dig that. Today’s post continues last week’s discussion on wholesale electricity markets, including capacity and energy-only markets. Summary of that post: Wholesale markets are headed for trouble because Electricity cannot and will not be stored in bulk quantities Society cannot function without electricity Grid loads are getting spikier, and that…

Good, Perfect, and Real Carbon Targets – Finale

By Energy Rant No Comments
In this week's Energy Rant, we're covering the final segment of good, perfect, and real carbon targets.There are two sources of carbon-free energy. First, we have the category of renewable with wind, solar, hydro, and some geothermal. Second, we have nuclear. Oops – third, we have efficiency and demand management. The electricity market is bizarre to me. Last week I crudely explained how the regional transmission authorities (RTO) and their twins, independent system operators (ISO), balance the grid in real-time. Power supplied must match demand with very tight tolerances of voltage and frequency at all times. The chart below shows…

Good, Perfect, and Real Carbon Targets – Part 3

By Energy Rant No Comments
In this week's Energy Rant, we're covering part three of good, perfect, and real carbon targets.In Part I of this series, we examined how various storage technologies work, their pluses, and minuses. In Part II, we put numbers to generation and storage technologies, including maximum power, duration of discharge (for storage), cost per megawatt and megawatt-hour to build and operate, and a slew of other great stuff. In Part III, we will size up the numbers from Part II to actual grid demand. The objective is to provide scale to see what we would need to pair high percentages of…

Good, Perfect, and Real Carbon Targets – Part 2

By Energy Rant No Comments
In this week's Energy Rant, we're covering part two of good, perfect, and real carbon targets.Last week we looked at grid-scale energy storage options for a couple of them, namely hydrogen and flywheels; I asked, “What could go wrong?” To be fair, my comment on hydrogen was its use as a buoyant gas to float the Hindenburg. Hydrogen, while very light, is explosively combustible, so putting it in a blimp was crazy. I always like to throw factoids in for budding STEM enthusiasts. Take a helium (non-combustible) balloon on a string, hold it by the string in a moving vehicle.…

Four Shades of Electrical Demand – A Riveting Cliffhanger

By Energy Rant One Comment
Last week I related electrical demand in kW with electrical energy in kWh. Energy is the area (power times time) under the kW curve. Without cheating, I’ll do an example. Elementary Calculus In energy-nerd world, a curve is a line of any form, including a straight line. Consider the simple ax + b curve on the right, where a is the slope and b is the y-intercept.  The equation is y = 2x +4. C’mon you had this in elementary school. Challenge yourself!If I want the energy consumed from hour two to hour ten, I simply take the integral of…

I Disrupt this Blog with Non-Wire Alternatives

By Energy Rant No Comments
As I read in The Wall Street Journal last week, I would like to disrupt the use of the overused buzzword disruption and the use of buzzwords in general, but I gotta do what I gotta do – talk about Utility 2.0 again. Come to think of it, the utility industry, and those that supported it, must have been asleep at the wheel in the 1990s. That was Utility 2.0 – deregulation, which didn’t work out so well with widespread bankruptcies, some of which exist to this day. Utility 2.0 gave rise to hucksters like Jeffrey Skilling and Ken Lay…

Bounteous Savings at Home

By Energy Efficiency, Energy Rant No Comments
Continuing on from the surface scratch delivered in Refrigerator Sitcoms and Lethal Toaster Ovens, this post provides more fact, fiction, and maybe some things you’ve never considered for saving energy. First, I came across some interesting data while reviewing evaluation reports for a major Midwest utility last week.  Recall in Bait and Switch, and again backed by ACEEE as explained just last week, regulatory agencies need to stop stopping fuel switching from dumb uses of electricity to smart uses of natural gas.  The specific item is the electricity guzzling clothes dryer.  As it turns out, the saturation of electric clothes…

Electric Bills and Waldo

By Energy Efficiency, Energy Rant One Comment
Recently, the American Council for an Energy Efficient Economy issued a report, “The State of the Utility Bill” and I thought, “now there is a topic for plenty of discussion.”  No, that was no joke, although there was an interesting finding that I found to be very hilarious:  All of the ~100 bills analyzed in the study (100%) included the amount due to the utility from the customer.  I would say not having the amount due would have its disadvantages.  (that WAS a joke) I’ve witnessed and studied many issues regarding end user understanding of energy, energy consumption, and end…

The Super Genius Grid

By Energy Efficiency, Energy Rant, Government, Renewable Energy, Sustainability, Utility Stuff 3 Comments
The barrier to having a decent energy policy is very similar to the barriers of solving illegal immigration.  Both the left and the right have their own vested interests in not fixing the problem.  I see the political spectrum as a circle, not a line from far left to far right.  It is a circle because when views get so extreme, they are supported by both the far left (e.g. Dennis Kucinich) and far right (e.g. Ron Paul).  Personally, I respect both of these guys and I have no doubt they are sincere in their beliefs and want the best…

TGTBT You Can Believe In

By Energy Efficiency, Energy Rant, Utility Stuff 2 Comments
In 1984 was not like 1984, I talked about greeting change with gusto to win the future but with few specifics.  This post will cover one such “innovative” way for all stakeholders to benefit from energy efficiency. The typical utility-sponsored energy efficiency portfolio works like this: A small percentage of billed energy consumption, aka a rider is paid by customers to fund EE programs. Programs provide incentives for energy efficient equipment and in some cases services such as studies. Evaluators determine impacts attributable to programs and make recommendations for improvement. Regulators oversee it all to help ensure consumers aren’t being…
