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,…

Two Questions for Electric Utility Stakeholders

By Energy Rant No Comments
Remember the theory that deregulation in the late 1990s would waive the need for energy efficiency programs? If not, you can read up on the Great Depression in Energy Efficiency, the origins of which began with the 1992 Energy Policy Act. I believe the theory at the time was that electricity prices would be so low that energy efficiency couldn't possibly compete. Or maybe the theory was, "We're deregulating; efficiency programs are a regulatory thing, so we no longer need them." I've written this blog for over 15 years, producing roughly 700 posts. I can't say that I've written a…

Data Centers Search for Electricity – Anywhere by Any Means

By Energy Rant No Comments
In the first post in this data center series, I introduced the staggering power density of neural computing systems used for artificial intelligence. At the macro level, in Northern Virginia alone, Dominion Energy projects data center load growth to increase from 3.3 GW today to 50 GW based on requested and projected load additions. Last week, in the fourth post, I described electric loads at the facility level, which reach well north of 200 MW. Only three to five hyperscale data centers, each with the power requirements of an aircraft carrier, can take all the power from a 1,000 MW…

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…

Electricity Shortages and What to Do About It

By Energy Rant No Comments
Some folks pin excessive weight on the federal government’s influence over our efficiency and load management industries. Even though billions/trillions of dollars are allocated through the “Inflation Reduction Act” and “Bipartisan Infrastructure Law,” those funds are fleeting. What’s more enduring? Rising electricity prices and load-balancing authorities are pushing for more baseload generation and transmission-line construction – things that are always met with stiff resistance by state and local governments and stakeholder groups. Utility Dive recently reported that electricity prices outpaced the broader U.S. consumer price index. Well, gee, why would this happen? Have fuel prices increased? No. You’d think electricity prices…

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.…

Using AI With Caution

By Energy Rant No Comments
Last week, I presented some findings that artificial intelligence can churn out dozens of product ideas in a fraction of the time humans can deliver. The AI bots provide higher-ranking ideas, so long as the criteria are defined, and the bot stays in the box. I also provided excerpts from a “help” chatbot that delivered no help but successfully raised my heart rate and blood pressure. Use It or Lose It Smartphones and computerized anything can make us dumber, less capable, vulnerable to power or network outages, and even bad directions. Last week, for example, I regretted turning navigation over…

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…
