Electric Vehicles as part of the Grid
I am working on a book about what we learned about operating electric utilities, and where I think that journey will ultimately lead...for those who continue the journey. This is an early excerpt about how electric vehicles fit into that future.
Electric vehicles (EVs) have arrived, even though there is a stubborn and hostile contingent of the population that claims they will never have anything to do with one. In 2022 EV sales hit nearly 6% of the total vehicle sales (double where they were at this time in 2021) and there is nothing to suggest that the surge in sales is over. Prices are coming down. Range is growing. The charging options are increasing, and even a non-car person must notice that the best designs and most clever technology is going into the EV offerings of each manufacturer.
All of this is happening as EVs are viewed only through the
lens of transportation options, but EVs will soon be much more than a transportation
option. EVs will become, once more electric utilities get in the game and offer
non-volumetric, cost-based retail rates, fixtures of the grid itself. For the
homeowner or small business owner, an EV will become a transactional device
that will facilitate exchanges between the electric utility and the EV owner.
This dispersed set of battery storage resources will also dramatically improve
the efficiency of the grid generation assets. The impact of the coming of the
EVs really cannot be overstated.
With modernized retail electric rates, and slightly improved
EV chargers, an EV will be capable of entering a matrix of available retail
rates, and the user’s transportation needs, to find a solution which will result
in taking energy from the grid to store in the EV batteries at a near-zero
energy cost. Conversely, if the EV is plugged into an advanced smart charger,
and if the EV owner so chooses, the utility will be able to buy energy back
from the EV when the utility needs additional resources. This transaction is
generally called Vehicle to Grid (V to G) and all the technology we need to deploy
this system already exists. That’s right. Your new EV can generate revenue for
your home or business! TVA can expedite the availability of these modernized retail
rates in the southeast by pricing their wholesale power accordingly. There is
not a technology problem, there is only the love of the status quo that
separates us from having the electric rate environment we desperately need.
Beyond a new revenue stream for the EV owner, EVs will also
transform the grid and help dramatically reduce carbon emissions associated
with electric power generation. EVs will perform this magic by reshaping the
problem that vexes the utilities and creates a large amount of their carbon
emissions. Everyone in the electric utility fraternity knows about the big
problem they all share. The problem is that each day the grid must deliver the
precise amount of energy required to satisfy the demand of the loads connected
to the grid, and that demand, when expressed as a simple graph depicting demand
vs. hours of the day, is not a neat flat line. Rather, it is actually a daily
sine-wave with the peak of the wave lasting about 12 hours and the valley of
the wave occupying the other 12 hours. It is the up and down shape of electric
power demand, which has existed for the last one hundred years, that makes the
generation of electric power so inefficient.
Up until recently, grid connected batteries simply didn’t
exist on any significant scale, so energy storage doesn’t exist on any
significant scale. As a result, utilities must follow that sine wave of daily
demand up and down, starting generation assets as load increases, idling those
assets as load eclipses the capacity of
those units and starting larger units (and if the happen to be starting something
like a coal fired unit that was idled 12 hours earlier due to declining load,
the starting routine is quite medieval – tons of fuel oil are dumped into the
boiler and set ablaze to get it ready to burn coal) resulting in massive carbon
emissions, as well as financial cost, every single day. EVs as part of grid can
begin to solve the problem. They can utilize the massive excess capacity that
is available each night, thus allowing the utilities to keep generation units
running, especially non-carbon emitting units like nuclear assets, and
renewables, thus stabilizing the grid and reducing the sine-wave daily load
shape. Thus, the amateur “analysis” of the carbon emissions density of EVs,
wherein some “expert” alleges that all kWh used to charge an EV is directly
associated with increased greenhouse gas emissions, is completely and totally
wrong, just like so much of what one finds on social media. EVs functioning as
grid appliances, as described here, will not only erase the greenhouse gas
emissions of today’s internal combustion engine powered vehicles, they will
also act to erase smokestack emissions from the generation of electric power,
by improving the daily load shape the grid must supply.

The Class of 1972 -- May Our Circle Be Unbroken
Figure 1 The Glasgow
High School Class of 1972 at their 10-year reunion at the home of Bettie
Biggers.
Fifty years ago, the GHS class of 1972
donned caps and gowns and were ceremoniously sent out into the world. Of
course, the same thing was happening in thousands of other cities, but I’m fairly
certain that none of those other graduates were quite like this group. In
support of my theory, let’s stand at 1972, and look back to 1922 for the fifty
years before this class, and also look at 2022 – the century that surrounds
this cohort.
1922 and 2022 are equally removed from the
high school graduation date of this group. As a member of the class, that
statement of fact is easy to get choked on. In 1922, World War I had just
ended. World War II would not begin for another nineteen years. In 1972, my
class viewed World War II as ancient history, but it had only been over for
twenty-seven years. We were more interested in the Vietnam War, as we hoped to
not be drafted to fight in it. Luckily that conflict ended in 1975, allowing
the male members of our class to escape being drafted by the skin of our teeth.
The class of 2022 hardly knows anything about the Vietnam War and the rift it
caused in our country. We lived, and continue to live, that rift.
1922 was lived to the music of the
roaring 20s. Rock and roll had not been invented, and neither had country
music. Though country music began to spring up a few years before we were born,
it was our generation that morphed country into rock, and that became the tail
that got our dog wagging. We were sandwiched between Woodstock (arguably the
beginning of the explosion of rock music) and The Last Waltz (arguably the end
of analog creative rock and roll of the 60s and 70s). Our taste in music was quenched
by a dizzying array of talented writers, performers, and producers. Their
products were served up to us mainly by AM radio, delivered to ancient monaural
radios in our cars and homes. In 1922 radios were still too big for
portability, and in 2022, no one even remembers AM radio, but we mid-century
kids lived by it. We caused the mighty WLS radio in Chicago to change to The
Big 89 and hire on-air talent like John “Records” Landecker, just to serve the
mid-continent the kind of cutting-edge rock music we demanded. Weather
conditions often combined with low quality antennae to make it hard to pick up
WLS, so we adopted the cutting- edge technology of 1970 – 8-track tape players
to supplant our appetite for music. We rocked, and so did the artists we
worshipped. WLS and John Landecker brought us to this religious fervor. We
worshiped at the altar of Pet Sounds and Led Zeppelin II.
Many of the artists that provided the
soundtrack of our youth appeared at Woodstock in 1969. The information about
this festival didn’t really make it to us until after the event. We were just a
bit too young to attend anyway. The Woodstock t-shirts started to appear in
Glasgow a couple of years later, but, fifty years later, they have never left.
Check through the t-shirt collection of a member of the class of 2022, and you
will likely find one. Also, if you rifle through the music collection on their
Spotify or Pandora accounts, you will find music by a lot of those artists who
first started singing to our class. Our music did not fade away, and it never
will. New music comes and goes, but our music (as well as our t-shirts)
remains. Go to a wedding or a bar mitzvah today and you will hear our music.
Sometimes kids today are listening to our music without even knowing it.
American Woman was not written and first recorded by Lenny Kravitz. Aerosmith
didn’t write Come Together. Landslide was around long before the Dixie Chicks.
Marilyn Manson cannot claim You’re So Vain, and Your Song isn’t Lady Gaga’s –
it is ours and Elton John’s. Will our Circle Remain Unbroken, as our music has?
In 1922 the most popular car sold was
the Ford Model T. That popularity remained unchallenged until we came along.
Our generation made the Volkswagen Beetle number one. It was affordable,
reliable, and marginally better than walking, but the radios worked great!
Still, it wasn’t a Beetle that we really wanted. Our car lust was reserved for
a Chevelle, Corvette, MG, Spitfire, Road Runner, Mustang, Olds 442, or a GTO.
The parking lot at GHS was not full of these machines because few of us had
cool enough parents to help us get one, but Wade Barton had a 1970 Chevelle SS,
and Craig Johnson had a 1966 GTO, and they were the coolest. In case you might
think that was just a 1972 thing, just check into any auto auction at the
prices people are paying to get one of these cars of our era. Just like our
music, today’s car market wants our cars too!
The class of 1972 was a lot more than
music and cars. The mid-century babies came along at an inflection point of our
country’s history. We wanted the Vietnam War ended. We wanted President Nixon
out. We wanted discrimination ended. We wanted equal rights for women, and we
became participants in all these movements. In Glasgow, we might not have
always understood all of these changes, but we were quick studies and learned
from outstanding teachers. We didn’t invent electricity or telephones, but our
contemporaries made them what they are today. Our cohort includes Steve Jobs,
Bill Gates, Bob Metcalfe, and Vinton Cerf. Together we built the internet, the
software that makes it work, and the devices we use to communicate and learn.
We are more than a list of people who were born in the middle of the 50s. Our
works will endure throughout the generations to come, and I expect our circle –
our bond with each other – will similarly endure.
A close bond isn’t something that
exists in every graduating high school class. We have each likely noticed this
in our children and their very loose bond to their class. We are different, and
that is one of the things that makes us special. Fifty years after our
graduation, we’ve learned that our lives didn’t pan out exactly as we expected,
and as depicted in Brian Wilson’s masterpiece – Pet Sounds. As the years roll by, our circle has shrunk by
a series of painful departures, each of which brought us sorrow. Still, it seems that our bond will remain. We
will mourn the passing of one of our own and then reform our circle by grasping
the hands that remain. So, here’s to the class of 1972. Have a great 50th
anniversary celebration. We’ve earned it! Let’s keep our circle unbroken – by and
by Lord, by and by.
Wouldn’t it be nice?

The Ending of My EPB Career - A Diary of the Events
I''m just putting this narrative here because it is easier for me to find after the many changes to what is accessible on Facebook.

Chapter Seven of Seven
Being There
An Autobiographical Account of My Life and Times at Glasgow EPB
William J. Ray
CHAPTER
SEVEN - The End
So, I
do have regrets, and my departure due to the unpopularity of doing my job by
recommending actions to a board, based on the knowledge gained by my team, still
stings...a lot. I spent the last 40 years head-over-heels in love with Glasgow.
Being spurned by it is the unkindest cut of my life. I regret not being
politically savvy enough to recognize the development of a new resentful and
angry mentality of some in the community. Further, I am ashamed of being
blindsided by the possibility that their discredited ideas and beliefs could be
embraced by local elected officials. While this malady did not originate in
Glasgow, I should have had my ear to the ground enough to predict its
emergence. I am sorry for not setting a better example for my families and my
supporters. In my position, it is not enough to talk the talk. I was supposed
to make sure that my walk was successful, not just accurate. I cannot help but
feel sorry for giving others the assurance that doing the right thing, would
always save one from injustice; and that discovery would not always lead to
implementation. I learned that being right can sometimes just not be enough. I
can only hope that they learn from what I failed to accomplish and move forward
with the resolve gained from experience.
I did
not mean for this to be so long. But I left out a lot of stuff about those 40
years, so maybe this should become a book. I left out the part where my blood
children were born, grew up in Glasgow, and went on to make me the proudest
Father ever known. I also left out a lot about the 124 other children – the
total that worked with me during those years. I consider them my family too,
and I am really going to miss them. I am a committed introvert (true, I swear),
so it has always been hard for me to let both of my families know just how dear
they are to me. Way back in 1984, when I was new to the EPB job, I discovered
it was much easier for me to communicate my feelings to the team in writing. To
make those writings personal, I began observing everyone’s employment
anniversary by putting my feelings about them into a hand-written note. I guess
I chose that method because I am always moved by a hand-written note from a
friend, so I hoped the work family would feel the same. During my tenure at
EPB, I wrote a lot of those notes – an amount commensurate to the love I have
for my team. They are important to me. I believe those notes were important to
my precious team, and I am really going to miss that process of making sure
they know how much I care for them.
I do
not want to fail to mention a couple of stalwart Board members who, in my mind,
qualify for mention like those I have already bestowed upon several other
community leaders I got to work with. John “Tag” Taylor and Libby Pruitt Short
joined the Board when the battle was already raging. They do not have the years
of experience of some of the citizens I mentioned above, but they were quick
studies and refused to accept the popular beliefs about me, my team, the rate
design we created, or the sustainability discoveries we made. They might have
had the toughest job of all of those who came before them, and they did that
job with conscience, study, and honor. I salute them.
As mentioned earlier, I was born in Glasgow and came back to Glasgow in 1983, mainly because of the rotten political environment that existed in Bowling Green at the time. I did not intend to stay in Glasgow a long time. Over the years, there were many offers of bigger jobs and equally bigger salaries, but I just never could come up with a complaint about my job at Glasgow EPB that was big enough to give me a reason to leave. I also loved the way Glasgow was growing and changing, and that I was a part of that transformation. All of the friends I have now, and hold dear, came as a result of my time at Glasgow EPB, and the gravity created by those friends held me to Glasgow. Most of all, I loved the team that I worked with, and I still do. While I still have not found a good reason to leave, it seems that my departure is the will of the majority. While I refused to grant their wish without a fight (I’m not throwing away my shot!), sheer numbers and the clear intention of a majority of Glasgow’s voters made it certain they would prevail. So, with this narrative I bid you adieu, with my heartfelt thanks for letting me spend my life trying to make the world, starting right here in Glasgow, better. I know those who befriended me in Glasgow made my world better.
It is
neither the calendar, nor the clock, that urges me to depart. Rather, it is the
compass – pointing out the direction to destinations I crave – ethics, justice,
and respect for science, that directs me to journey away from Glasgow EPB. This
narrative should answer a lot of questions about my tenure in Glasgow, but one
still remains – what comes next? Tomorrow the sun will rise. Who knows what the
tide could bring?

Chapter Six of Seven
Being There
An Autobiographical Account of My Life and Times at Glasgow EPB
William J. Ray
CHAPTER
SIX
It was
with the scars from the battles we already fought, and the losses we incurred
therein, that were with us as we trudged into the biggest conflict of my career.
We were driven by the injustices we found, and the understanding that someone
had to confront the problems we discovered. The creation of a new rate
structure for electric power was not a fight we went looking for. Rather, it
came looking for us. The rate issue arrived in the data gathered by one of our big
research projects that tested the viability of advanced energy meters using our
broadband network and allowed us to gather several years-worth of data about
how Glasgow customers use the energy we sell. Instead of gathering only 5
digits of data from electric meters, once very thirty days, suddenly we were
gathering that data every 15 minutes. As exceedingly bright members of the EPB
team began to analyze that data by comparing our sales data for nearly 8,000
customers to the wholesale energy data provided by TVA, a story began to
materialize – one that could not be ignored – one that held the key to upending
the century-old electric power business.
In
2014, the brave Board that existed then (Norma Redford, Jeff Harned, Cheryl
Berry Ambach, Jim Lee, and Karalee Oldenkamp) began to delve into the facts
that the team was unveiling in the data we mined. The findings included
many inconvenient truths. We discovered that the existing rate architecture
resulted in only those customers using the “average” amount of energy, and the
average amount of coincident peak demand each month, were paying an amount
directly connected to the wholesale cost of delivering that energy. Our
discovery showed that very few real customers actually used the mathematical
average amounts for a given rate class. Further, the facts revealed that
customers using less than the average volume of energy, paid far less for their
electricity than the actual cost of purchasing and delivering that energy.
Conversely, we found that customers using more than the average volume of kWh
(while using an average amount of coincident peak demand), were being forced to
pay much more than the actual cost of the power delivered, and those were only
the results within the residential rate class. Over the months, the facts also
revealed that customers in the large commercial and industrial rate classes,
when actual hourly consumption was compared to actual hourly wholesale cost,
were paying much, much more than the cost of serving them.
There
were other previously hidden truths discovered. We found that large companies
were being forced to subsidize other classes of customers. Perhaps the biggest discovery,
and the one completely ignored by my vocal critics, is that there really is no
significant relationship between low energy usage and household income. None.
The image of cost-based rates bringing hundreds of older folks into a life of
misery is conjured from nothing but misguided imagination. Much more common,
and where a direct relationship was found to exist, is that a significant
number of customers with low household income find themselves living in
substandard housing, and those households were found to use more than the
average consumption upon which the old rates were designed. The poor, in
substandard housing, were paying more than their fair share of EPB fixed costs
under the pre-2016 rate design.
These
findings were considered by the EPB Board throughout 2013, 2014 and early 2015.
I can assure the reader that no one on that Board wanted to be placed in the
position of having to deal with this issue that permeates all 3,500 electric
utilities in the U.S. They faced the old energy utility habit of ignoring the fact
that the rate architecture, the one in place since the early 1900s, did not
accurately produce billing that was connected to actual cost of service. They
could have adopted that common industry habit and hoped that their terms on the
Board would expire before those facts leaked out to the customers who were
being treated unfairly, but they did not do that. Instead, driven by their
wisdom, integrity, and ethics, they pursued a course of “good trouble” and
followed the words of Martin Luther King from his March 1965 speech in Selma,
Alabama, “A man dies when he refuses to stand up for that which is right. A
man dies when he refuses to stand up for justice. A man dies when he refuses to
take a stand for that which is true.” That EPB Board rose up, and they
directed my team to develop a rate that brought accuracy and justice to the way
people in Glasgow purchase their supply of energy, because anything else would
not be right. My team followed their direction and developed what energy and
rate experts who have examined it call, the most simple and elegant solution to
electric power retail rate design which exists today. Although that move was
largely misunderstood, and although that action of standing up for what is
right ultimately caused their departure, and mine, I am proud of what the Board
and my team accomplished then, and what they are still accomplishing now. If
given the chance to go back and do it all again, I would not change a thing,
because it was that new relationship between electric power production and the
retail sale of the product that revealed the most powerful truth of my
career.
For over a century, the electric power systems have operated on the belief that the daily demand curve for electric power was unalterable. This belief drove the industry to over-build generation capacity and over-mine the fossil fuels that have long been used to burn to produce the steam necessary to create the flow of electrons we hold so dear. But our work in Glasgow began to show that the daily peak demand could be flattened. It showed that off-peak power could be stored in batteries, and that our broadband network could be used to organize electric power production, storage, and consumption, into a shape which could be satisfied using mainly renewable energy sources. Before some very angry and backward voices organized to put the kibosh on research projects in Glasgow, using misunderstanding and a shocking disdain for expertise, we gathered enough data to glimpse a world with dew still on it. We discovered and demonstrated how the ratio of energy usage to peak demand could be drastically improved, using technology and cost-based rates. We saw a way toward a sustainable energy system that stole the ideas of energy conservation and storage from nature. We revealed those things before a few misguided people, promoting their local brew of uninformed populism, killed the appetite for research and discovery in Glasgow. Allowing them to do that is my greatest failure.

William J. Ray
CHAPTER
FIVE
Although
we won many of the battles that sought us out during my time at the EPB, we
experienced some gut-wrenching casualties in the process. Some of those
consisted of cherished members of the team leaving for other jobs. More
casualties came in the form of experienced essential members of the team who
chose to retire long before their talent diminished, just due to the stress
involved in the EPB world. This challenge will continue to be a problem after I
am gone. But, by far, the most crushing loss of members of the team came from a
couple of untimely deaths. Jama Young was our first Technical Services Manager.
I wanted a small group of folks to create a “skunk works” operation to study
evolving technologies and bring the deserving ones into our portfolio of
products. Jama was designed for the job. Of all the people I have encountered
during my long career, Jama was one of the most brilliant and capable. I fully
expected her to take my place when I departed. In an unjust twist of fate, she
left this world before that could happen. We think so much of her, that we
still honor her by naming the building that holds most of Glasgow’s essential
technology after her. The wound left by her passing has never healed.
Janice
Crenshaw also left us when we were counting on her the most. Janice was much
different than Jama. Janice was not a technical wizard. Rather, Janice was a
customer relationship expert. She worked in our lobby, where she waited on, and
counseled dozens of customers each day. While anyone can learn to talk to
customers and fulfill their wishes, I’ve never seen anyone else with Janice’s
capacity to make each of those interactions something that made the customers
involved feel loved and respected. We are still trying to get over her loss as
well.
Continuing the EPB mission is impossible without finding, hiring, and retaining more team members like those who we lost during my years.
