Full Spectrum Virtual Power Plants

By Energy Rant No Comments
A couple timely articles and posts have dropped since I reintroduced virtual power plants (VPPs) last week. First, I'll share a LinkedIn post from Matt Golden, CEO of Recurve. He wrote:  "VPPs being defined as dispatchable loads only, is just plain wrong. Just like the grid is supplied primarily by load following and base load power plants, with a small but important amount of peak dispatchable emergency power, VPPs are a combination of long-term load modification and dispatch.  The vast majority of the potential to shape load with virtual power plants comes from things like heat pumps that provide better air conditioning and attic insulation…

Virtual Power Plants Order in Load Management

By Energy Rant No Comments
Virtual power plants (VPPs) represent a considerable slice of the clean energy race these days, and for a good reason: policy continues to favor intermittent renewable energy supply over baseload nuclear and dispatchable natural gas assets. Load needs to follow supply. Theoretically, we would need a lot of load flexibility for many hours and sometimes days to keep the grid energized with, mmm, 50% renewable energy. As of 2021, the renewables slice of the supply pie was around 13%, so there is a long way to go.  The DOE's Virtual Power Plants Commercial Liftoff report declares the United States needs 80-160 GW…

Electric Ratemaking Basics and Load Flex

By Energy Rant No Comments
In the last two Rant posts, we explored dated benefit-cost tests for energy efficiency and demand response programs and introduced flaws with dated ratemaking schemes. Both constructs are based on a century-old “cost of service” business model for monopolistic utilities. In a nutshell, the cost of service includes the debt and equity financing of generation, transmission, distribution, and operations and maintenance, which includes employees, fuel, storm damage repair, and arboriculture. Add up all those costs, including competitive investor returns on equity and debt, and then smear those costs as equitably as possible across the customer base. The sum of those…

Unheard of – Two Factors Exacerbated Elliot Power Shortages

By Energy Rant No Comments
The Energy Rant features content you will not find anywhere else, and this week we have blazing examples featuring two unpublished (go ahead and look) contributions to the grid crisis of Christmas weekend 2022 and winter storm Elliot.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…

Reorganize Portfolios and Redirect Incentives for 10X Impacts

By Energy Rant No Comments
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…

Demand Response Primer

By Energy Rant No Comments
Last week I described how net zero sounds grand, it’s easy to do, but it doesn’t work to support the transition to a clean-energy grid. The reason is that everyone, whether utilities or customers, overproduces simultaneously, and then later, customers all need energy from thermal power plants simultaneously. We have an exploding deficit of customers to take that overproduction and shift load or store it for use when intermittent renewable supplies shut down. In Renewables at Scale, I described how renewable supply and batteries would never be sufficient. The gaps in intermittent renewable supply are too big for batteries to…

Cure Net Zero with Demand Response

By Energy Rant No Comments
I lambasted net zero many times, one time calling it an unserious weapon against climate change. Why is that? We’re going to see in this post. What is net zero? Simply, it is a building or property that produces as much renewable energy on-site as it consumes, typically over a year. Some utilities claim their net zero trophies for producing as much renewable energy as their customers buy. Why is Net Zero a Con? To answer this question in one word; exports. When a property or utility generates more electricity than it consumes, it must be exported to someone else.…

Managing Utility Bills with Automation and Information

By Energy Rant No Comments
Another week and we have two more dire warning shots of forecast blackouts this summer. These come from The Wall Street Journal and describe challenges from the Midcontinent Independent System Operator (MISO) region to California. Michigan’s Palisades Nuclear Generating Station shut down permanently on May 20th taking out 6.5% (800 MW) of the state’s electricity supply (gulp). The Journal notes it is part of Michigan’s transition to all renewable energy. They also write that it was slated for closure for five years, but Governor Whitmer waited to throw a last-minute Hail Mary just one month before closure to the federal…

Utility Relationships and Hookup Puns

By Energy Rant No Comments
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…

Looking back at 2021 Forecast

Looking Back at the 2021 Forecast

By Energy Rant No Comments
Predicting the future with infinite degrees of freedom is hard, especially when projected years into the future. A few years ago, Public Utilities Fortnightly posted an article about the accuracy of The Jetsons forecasting the future. William Hanna and Joseph Barbera got about half of it right, which isn’t bad for a 60-year projection. I researched this because I found an error in the PUF article that said there were no area codes in Jetson time (1962-1963). A quick online search indicates area codes started in the 1940s. Technologies from the Jetsons that we have today include moving walkways, treadmills,…
