A Better Value of Economic Dispatch

By Energy Rant No Comments
Last week and many other times, I've written about soaring electricity loads and prices climbing even faster. The reality is prices are rising much quicker than load. For example, grid loads in Oregon have increased at a compounded rate of a modest 2%, while prices have risen by a compounded rate of nearly 9% in the same period. Why is that? Wholesale Electricity Supply Curve A year ago, I demonstrated using a typical generation supply stack from PJM, reposted in Figure 1. Each dot shown represents a generator. Refer to one of my concluding questions last week, "Will stakeholders increase,…

Herding Chickens Through Modern Energyscapes

By Energy Rant No Comments
A recent study, Stacked Energyscapes, led by professors at Loyola Marymount University and Penn State University, caught my eye. The paper describes webs of complexities associated with transitions from fossil-fuel-powered economies to clean-energy economies. I burrowed into this paper as a glutton for third, fourth, and fifth-order (and beyond) downstream chain reactions and the universal picture. The Inflation Reduction Act was deployed in part to provide a 10% tax break bonus for clean energy development in communities that have been negatively impacted by decreases or closures of fossil fuel extraction. However, developers in many locations, such as the enormous Permian…

The Energy Transition Grind

By Energy Rant No Comments
Longtime Rant readers know I keep both feet on planet Earth, capturing all sides (typically two) and explaining, yes, but (fill in the blank). For the next case study, I was recently presented with a slide deck from the Rocky Mountain Institute (RMI), The Cleantech Revolution, It's Exponential, Disruptive, and Now. There are many brilliant people at RMI. Amory Lovins, its cofounder, is one such brilliant revolutionary. Amory's famous home in the Rockies can grow bananas in winter. That's great, but is it scalable? It is 4,000 square feet and was completed in 1984 for $500,000, which would be over…

Theory #2 For Batteries Increasing Emissions

By Energy Rant No Comments
As a glutton for punishment (I look forward to getting past sciatica so I can run marathons again), I tasked myself with getting to the technical bottom of this article from Utility Dive: Energy storage for grid reliability can increase carbon emissions: University of Michigan study. The article doesn't get into the details, so I dived into the source document sponsored by the University of Michigan – a brutal read – like the last miles of a marathon, maybe Heartbreak Hill or Central Park. I spare readers the pain so they can follow along from their La-Z-Boys.  I know enough about wholesale electricity markets to use terminology and…

Solar Wars

By Energy Rant No Comments
A year ago, I introduced the mantle curve to illustrate California's overgeneration of solar power and the resulting need for curtailment. In 2022, California's scoping study set a target for an additional 60 gigawatts (GW) or 60,000 megawatts (MW) of solar generation to be deployed by 2030. Below are the forecast curves from last year's post in May. The system was penetrating the overgeneration region, but the net load was above zero MW. Similar forecast loads from last week are provided below. We see the net load digs below zero MW, into the mantle. Granted, the first chart represents a week in May last year, while the second represents…

24-7 Carbon-Free Energy Hall of Mirrors

By Energy Rant No Comments
The ESG cabal seems to be drawing up another hall of mirrors to persuade credulous stakeholders and bystanders that they are siphoning only carbon-free energy (CFE) from the electric grid. The Electric Power Research Institute calls it 24-7 carbon-free energy, oddly enough. “Large companies from Starbucks to eBay have pledged 100% renewable energy targets to offset greenhouse gas emissions from their electricity use. Recently, several large companies, including Google, Microsoft, and others, have started procuring something called carbon-free energy that more closely matches their corporate electricity load on a 24/7 hourly basis. This is known as 24/7 carbon-free energy.” Unquestionably,…

Micro Rant Harvest

By Energy Rant No Comments
It’s fall, and that means it’s harvest season. So, this week, we’re providing a cornucopia of micro rants and information. I’m Alexa, and I’m Here to Help This headline caught my eye, ‘Alexa, I’m cold’: Government teams up with Amazon for energy saving campaign. The world’s fifth largest company, dominant retailer, data center behemoth, and tech giant partners with the government to use its in-home listening device. What could possibly go wrong? I recommend 1984, the book. EV Repair Black Market The Wall Street Journal reported, via email, that totaled Teslas from Western nations are being shipped to Ukraine and a…

Iowa: Case Study in Major Renewable Supply

By Energy Rant No Comments
It seems like someone coined the line, “what others are saying,” but I can’t find it. So, maybe I’ll coin “what others are saying” with that; here is what others are saying: lawmakers and policymakers should read the Rant. Here is why, starting with this PR Newswire: “Recent studies indicate that as of this year, 99% of all coal plants in the U.S. were more expensive just to operate compared to building new wind and solar. This is especially true for Iowa, where all coal used in power plants must be imported, costing ratepayers both the cost of coal and its transport.…

Modern Electric Rates from the Slide Rule Era

By Energy Rant No Comments
Last week, we looked at Total Resource Cost (TRC) tests that were developed decades ago to put a high value on avoided source energy costs. That was right for the time, but not today. I demonstrated that energy costs, mostly dominated by natural gas, are near historic lows, while zero-energy-cost renewables supply more electricity than coal-fired generation. Of course, renewable sources have zero source-energy consumption. Yet, utility commissioners are laser-focused on keeping electricity prices in check and maintaining the reliability of the electric grid. Electric Rate Basics Like the TRC, most utility rates (tariffs) are stuck in the 1970s. I…

The TRC Is Calling – Has Anyone Seen 1979?

By Energy Rant No Comments
Last week Michaels Energy delivered a webinar, Achieving Grid Resiliency with Thermal Energy Storage. There are about 70 gigawatts of refrigeration load in the United States frozen storage and chilled-water HVAC systems alone. That 70 GW does not include distributors like Sysco or U.S. Foods, grocery distribution centers like Walmart or Kroger, food manufacturers like Tyson or Nestle, grocery stores, convenience stores, or restaurants. Add it all up, and well over 10% of the total peak load in the U.S. is sitting there in bags, boxes, and buckets of food, waiting to be used as a flexible load-shifting and management…
