The Energy Rant features content you will not find anywhere else, and this week we have blazing examples featuring two unpublished (go ahead and look) contributions to the grid crisis of Christmas weekend 2022 and winter storm Elliot. A few weeks ago, Utility Dive reported that gas-fired generation represented 70% of the PJM unplanned outages during Elliot. That represented about a quarter of PJM’s capacity. The days of interest include Friday, December 23, and December 24. Here were the generation mixes for those days. Hmmm. What didn’t fail? Coal and Nuclear. Why? Because they each come with months of fuel…

A couple weeks ago, I quickly read this article, Cracking the Code - Aligned Incentives, on EnergyCentral.com. It concerns incentives for high-performance employees, but my read was about incentives for efficiency programs. It applies to that too. Myopic Focus I wrote about short-term focus many times, including last week – if your lips are chapped, stop licking them – short-term gain for longer-term pain. Efficiency portfolio administrators, typically utilities, want long-lived measures, deep energy savings, and instant savings. The demand for instant savings is like harvesting the carrots at day 30 rather than at day 70 maturity. SEM Myopathy As…

Last week I read a statement from a retail energy provider. It said, “100% green rates, always.” It doesn’t work that way. An aggregation of power sources, including renewable, nuclear, coal, and natural gas, are supplying the grid at any given time. The little electrons aren’t tagged by source and routed to any given customer(s). Second, even if that were impossible, er, I mean, possible, it’s shoving more hydrocarbon electricity onto someone else. In this way, it’s the same as the net zero con. Cheap but Unreliable Generating renewable power is easy and inexpensive, but as described in the net-zero…

The last few posts featured an overview and complete report card on load management to get beyond net zero to real zero, a term I discovered last week. As promised, I will describe some permanent peak load reduction opportunities this week. Like many efficiency solutions, blocking and tackling approaches are the most effective. Peak Load Reduction – New Construction I’m going to stick with some big hitters. A person could write forever on this topic. Home Envelope Single-family homes must be super-insulated to minimize heating loads in cool/cold climates. The cartoon below provides a nice example of super-insulated versus code…

This is the third installment of this series in demand response (DR) and load management. In the first post, Curing Net Zero described why net zero is not the answer: everyone over-generates with solar or wind simultaneously, and later, everyone needs power from something else simultaneously. The second post, Demand Response Primer, gave an overview of families and specific types of load management. This time we’re looking at my scorecard of these DR resources. Here is my report card, including critical factors for each DR resource, followed by discussions of what it means. What does this poppycock mean, Jeff? Peak…

I attended Peak Load Management Alliance’s 45th Conference in Baltimore last week, where I captured a quote that went something like this: the difference between energy efficiency and demand response is that demand response is a relationship between utility and customer. In contrast, efficiency is a transaction or two followed by the customer and utility parting ways. I thought, hmm, so it’s like renting an apartment versus a hotel for a night or two – or a long-term relationship where two people actually know each other’s names versus a hookup. Ok. Hookups Most of us reading this cannot relate to…

“Can I ask a question?” My response to that, in good company, is, “You just did. Would you like another chance?” Now that, my friends, is a paradox. As you ought to know, I’m preparing a mind-blowing three-hour course on decarbonization for AESP’s Spring Training. One conclusion: 100% decarb is going to take decades and it will be expensive and disruptive. A lot of progress has been made, but it has been easy for reasons I will explain next following this chart, which shows how decarb cost will soar as the percent reduction increases. Average CO2 emissions per kWh produced…

A few weeks ago, we reviewed electricity storage technologies, barriers, and issues. One storage technology is the lowly lead-acid battery, which forms the backbone of uninterruptible power supplies for data centers. They are inexpensive with readily available materials, are 100% recyclable, and therefore, they get no attention. Why? Elon Musk, the ultimate hype provocateur. What happened to the PowerWall, by the way? Disruption of rational thought? A web search of “annual Powerwall sales” results in nothing but distantly tangential content. Similarly, the utility industry, our industry, other companies, and people chase the flashy objects (squirrel!) to obtain decarbonization targets. Flash…

You all know people who are always going to do something great but never make it happen. Consider the hapless New Year’s resolution for which someone plans to lose weight. They successfully diet between a cheeseburger and fries for lunch and a mound of pasta with rich sauce for dinner: the “diet” lasted a few hours and accomplished nothing. The empty New Year’s resolution de jure for decarbonization is net zero, where similarly, there is excess at times and shortages at other times. Whether it’s net-zero-energy building design or net-zero-carbon electricity production, the achievement is easy and similarly not helpful.…
