Electric Utility 2050

By Energy Rant No Comments
As we prepare to take our energy storage solutions to market, I gathered recent news reports, analyzed them all, and came to some conclusions. I concluded that utilities, and especially regulators, need to think differently. What got us here – constant load growth and earning returns on conventional rate base by building power plants, transmission, and distribution systems – will not get us there (the energy transition) without turmoil and upheaval.

The Power Grid’s Glide Path to Reckoning

By Energy Rant No Comments
“The U.S. electrical system is becoming less dependable. The problem is likely to get worse before it gets better.” – The Wall Street Journal, February 18, 2022. I can take down another one of my seven predictions for 2022. Some numbers from the WSJ: in 2000, there were fewer than two dozen major disruptions. In 2020 there were more than 180. Customers experienced over eight hours of disruption (on average) in 2020, more than double the number in 2013 when the government began tracking this metric. The Journal reports several reasons for the rickety grid. The Markets’ Disincentives for Reliability...

Regulation v Deregulation in True Color

By Energy Rant 3 Comments
Recent projects have led me to examine how deregulated electricity markets work. Since I am naturally curious, I wanted to investigate differences between electricity price performance of deregulated states versus those of regulated states. This week we examine the impacts of regulation/deregulation on pricing, and next week, we will look at the impacts that renewable energy has on pricing. Data used come from the Energy Information Administration[1]. Figures lie, liars figure, but Jeff merely presents all data available for you to decide, pound your chest, or cry. That is your prerogative. Often data which do not support a narrative is...

Electricity Storage by the Other NWA; Chum v Beluga

By Energy Rant No Comments
Energy storage is easy and cheap. Grid-grade electricity storage is complex and expensive. Definitions of energy storage vary. Some consider hot water, chilled water, or ice to be stored energy. It’s really storing the benefits of energy consumption. For phenomenal refreshers and mental strolls down memory lane, see Storing Energy v Storing Benefits and Something Old, Something Old. Why is grid-scale electricity storage so expensive? To answer this question, let’s consider the forms of storage and the hurdles that must be overcome to make it cost effective. Electricity Storage Challenge #1 = Inefficiency First, we have the storage of potential...

Question: Carbon and Benefits? Answer: Efficiency

By Energy Rant 3 Comments
“Don’t drink the Kool-Aid” and being as objective as possible are how I roll. If you feel otherwise, by all means, let me know. Driving across Southern Minnesota recently, a billboard like the image nearby caught my eye. I thought this would be worth looking into to see what they have to say. As I expected, the paper it promotes is jaded against wind energy. But what arguments do they make? Are they legitimate? Wind is Fuel When thinking about wind-driven power generation, it has a lot of hurdles to overcome to be cost-effective. One near the top of the...

Powering Lives at Lowest, Convenient Cost

By Energy Rant No Comments
I spent last week at the Association of Energy Services Professionals (AESP) National Conference in New Orleans. Our industry is in transition once again. Substantial changes are on the horizon. Let’s recap some highlights and lowlights in the utility and demand side management industries the past few decades. As nuclear power was going to be too cheap to meter in the 1970s, the oil embargo, Jimmy Carter sweater speech, and the Three Mile Island nuclear accident resulted in a radically different direction for our energy future. On the heels of the above, and the global cooling threat (check out the...

Efficiency by Baby Steps and Giant Bounds

By Energy Rant 2 Comments
This post features concepts everyone can use to identify terrific savings opportunities, even if you did not take beloved calculus and thermodynamics. Let’s review a general hierarchy of typical energy efficiency families: 1. Shut it off 2. Slow it down, set it back (temperature, etc.) 3. Reduce waste 4. Retrofit or replace with efficient equipment Those are all wonderful and probably capture over 98% of portfolio savings. Even newer programs like behavioral, retro-commissioning, and strategic energy management merely pursue these items. What’s left? Smart design. I.e., 5. Don’t be stupid Or for the glass half full message, it would be...

Exergy, Easy – Heavy Savings

By Energy Rant No Comments
Exergy is a sexy word (maybe only to energy nerds), but it represents a vital class of measures and opportunities as we sprint head-on into the game changer (cliché alert) that will be the post-gravy-train-of-lighting-retrofit-era of energy efficiency. Pay attention! Exergy, also known as availability, is the total useful energy that can be captured before a system comes into equilibrium with the surroundings. Equilibrium can be as simple as a mass coming to rest. Potential Energy Consider a hydropower plant. The potential energy is in the form of elevated water on one side, the reservoir, and a shallow stream for...

DoGooder Equity

By Energy Efficiency, Energy Rant 2 Comments
Upon reading some manager/principal/owner interviews in business publications, the publisher asks, “What keeps you awake at night?”  My answer to that would be: Nothing.  The reason for this is utilities are regulated monopolies and the energy efficiency program portfolios they run are cost effective.  I.e., we, as an industry, are contributing to net wealth generation for consumers and not just redistributing it – it’s EE or power plants, poles and wires and either way, the consumer pays, and we are helping them pay less. A major reason I am a huge advocate of EE programs is that they are cost...

Dodging the Absurd

By Energy Efficiency, Energy Rant No Comments
In Stalin Lives, I mentioned our plan for securing an ENERGY STAR® clothes washer and dryer for our house.  What I did not mention was that the local appliance stores do not even stock gas-heated dryers. Think about how stupid it is to generate electricity with maybe 35% thermal efficiency, lose 10% of it to line losses, as discussed last week, in it’s transport to the home and then use this high-value energy as a toaster coil to dry clothes.  We, as well as I am sure millions of households, use “gas”, natural gas in our case and propane in...
