The Next Energy Frontier in Texas

By Energy Rant No Comments
Pouring Into Texas Money talks, and if states were holding speech contests, Texas would be the frontrunner. While states like California boycott conferences in Florida and Texas over DEI and reproductive policies, those things, unfortunately, don’t matter to some of the most progressive private-sector companies. Last week, Apple announced plans for a new 250,000-square-foot facility to manufacture servers to serve the artificial intelligence market. Per The Wall Street Journal, Austin has the largest concentration of employees outside of Cupertino. I would guess within a decade that Apple will move its HQ to Austin. The Journal also reports Meta moved its…

Electrification Gangsters

By Energy Rant No Comments
Last week, I explored the macro impacts of electrifying our heating systems and using ground source (aka geothermal) heat pump (GHP) systems rather than cold-climate air-source heat pumps (CCHPs). In a nutshell, deploying GHPs in the colder regions of the country would reduce necessary electric demand growth by 77 percentage points compared to CCHPs. Ground source heat pumps would also avoid the construction of 43,500 miles of transmission lines, enough to crisscross the United States 16 times. At $2 million per mile, that's $87 billion. That's a rounding error in Washington, but it's a lot of money for the rest…

Boring DERs, Saving Billions with Geothermal Heat Pumps

By Energy Rant No Comments
Over the many years I have taught electrification basics for the Wisconsin Public Utilities Institute’s (WPUI) Energy Utilities Basics course, I dive deeply into heat pumps and their impact on the grid. I explain the messy chart in Figure 1 like a palm reader, except I have engineering behind my assertions rather than mystical conjectures. Cold-Climate, Air-Source Heat Pump Performance As outdoor temperatures fall below zero Fahrenheit, as they do from the panhandle of Idaho and Wyoming across the country to Maine and Massachusetts, cold-climate air source heat pump (CCHP) performance and capacity dive while heating loads increase. The chart…

A Twofer: Syncing Power Generation With Soaring Loads

By Energy Rant No Comments
One of many sources of information that fuel my brain to write this blog is the American Energy Society’s Energy Matters newsletter. The newsletter features many items I don’t find elsewhere, and impressively, they seem unbiased – it is what it is. Power Generation According to a linked New York Times article, 200 coal-fired power plants have closed in the last decade, with 200 remaining and 50 slated for shutdown in the next five years. They also linked to this informative, interactive map showing power generation from the Energy Information Administration. The black dots represent the remaining coal-fired power plants,…

A More Cost-Effective Energy Transition

By Energy Rant No Comments
A recent Realclearwire.com article noted that since 2021, the cumulative effect of persistent inflation has reduced Americans’ purchasing power by 19%. Since 2021, grocery prices have increased by 21%, gasoline prices have increased by 47%, shelter costs have increased by 20%, and electricity costs have increased by 30%. Wholesale prices rose at the fastest rate in April 2024 since April 2023, signaling persistent pressure on retail prices for months to come. When I read the data, I think of energy prices rolling through everything, adding to consumer prices across the board. For example, diesel fuel prices roll through the food…

What’s on the Minds of Utility Consumer Advocates

By Energy Rant No Comments
This week I’m focusing on the concerns expressed by members of the National Association of State Utility Consumer Advocates, NASUCA, which met in parallel with NARUC in Austin, TX, a week before last. The topics of concern include outage risk, high prices, and related energy poverty. Outage Risk In the short term, this year or next year, I can only repeat what the experts are saying. Jim Robb, President of the North American Electric Reliability Corporation (NERC), said the bulk power system has seen steady improvement . At the same time, the risk is “terrifying” due to peak load growth…

What’s On the Minds of Utility Commissioners

By Energy Rant No Comments
Last week I attended the National Association of Regulatory Utility Commissioners (NARUC) Summer Policy Summit in chilly Austin, TX, where running shoes never dry. I also learned that the National Association of State Utility Consumer Advocates (NASUCA) holds a conference in parallel in the same venue. This post begins to provide an overview of issues and concerns discussed at the conference, summarized in four words: rising rates declining reliability. Let’s get into it. Rapid Thermal Power Plant Retirement Results: Grid Stress This section may be summarized using the title of the Tuesday panel discussion, “On the Brink: Reliability Challenges and…

A Prolific Coincidence in Power Generation

By Energy Rant No Comments
When I dig in to research a topic for the Rant, it’s a bit like American Pickers with Mike and Frank, but not drama. Pickers cover thousands of square feet of junk or treasure. I suppose the contents of this blog could be described as thousands of words of junk or treasure. This week we “pick” the last bits from the research that came from the paper, Climatic Impacts of Wind Power.This week we examine data representing the Midcontinent Independent System Operator’s (MISO) load and wind supply curves. First, the MISO territory is enormous, stretching from the Gulf of Mexico…
