USPS To More Than Double Order of Electric Trucks (thehill.com) 223

The U.S. Postal Service will order more than twice the number of electric vehicles initially projected for its new fleet, the agency announced Wednesday. From a report: The move follows months of controversy after the Postal Service initially sought to make about 10 percent of its fleet electric. Now it plans to make at least 40 percent of its fleet electric. The Postal Service said in a statement it adjusted the fleet's Supplemental Environmental Impact Statement to include more electric vehicles under the current contract. The Postal Service is targeting a purchase of at least 25,000 electric vehicles, it said. The Postal Service said in February that its initial order to have 10 percent of its new trucks be electric included an option to adjust the percentage later, but the announcement sparked pushback from members of Congress and the Environmental Protection Agency. The Postal Service maintains the largest vehicle fleet in the federal government, and critics argued that not including more electric vehicles in the fleet would fly in the face of President Biden's push for the federal government to pursue carbon neutrality.

USPS To More Than Double Order of Electric Trucks

  • I am all for the move to electric vehicles. I am just concerned that we don't have an electrical grid robust enough to support the speed at which the change could happen. Could off-peak become a secondary peak usage time if everyone is charging their vehicles at the same time?

    • Properly shoring up the energy grid shouldn’t be thought of as something optional. Leaving the infrastructure to rot becomes profitable, especially so when outages can cause rate increases which wind up making more money than reliable power generation. Electricity is one of the most versatile types of power we use, and it should be strongly regulated as a utility, one required to be cooperative with neighboring grids.

        Outside of Texas, utility companies are pretty good at keeping their grids serviceable. By and large utility companies see the adoption of electric vehicles and are planning accordingly; rolling upgrades into their planned maintenance and implementing incentive programs to incentivize EV charging during off-peak.

        Generally in the US, generating capacity is owned and operated by private companies who sell their electricity to the utility, who in turn sells it to the consumers. As demand increases the wholesale price of electricity goes up as well, and private companies will (and have been) investing in more capacity.

        This isn't a hypothetical, this is what's actually been happening. I can pull up trade articles from nearly a decade ago explaining how utility companies have been planning ahead. Market share of EVs in the US is about 5%, and they accounted to about 5% of all sales in Q4 of 2021. This isn't a transition that will happen overnight.

      • If we had that technology is always daytime somewhere

        Even if it were practical to rely on Europe or Asia for "daytime" when the entire continent is dark, you would have to be incredibly stupid to do so. Friendly neighbors are not guaranteed to be friendly always, witness the obvious situation with Putin and gas in Europe, but even close to home we have examples like Line 5 between Canada and the US;

      It's already really bad, talk about heat waves and rolling black outs across the US. The infrastructure is old and having private companies running all of it means they've invested absolutely as little as possible to maintain their monopoly profits - because, what's oversight?

      Postal vehicles are nearly ideal for electric drive: lots of start and stop, returning to a central spot overnight, and they don't ever get far from the charging station; not even a need for long-range between charge.

      They'd be charging overnight. At the current number of electric vehicles, this is the time when electric grid usage is very low, and electrical power is cheap. Postal vehicles won't cause electric grid problems, in fact, the opposite: they will be a useful load when few other loads are using power.

    • The necessary upgrades will never occur if the can keeps getting kicked down the road.

      Having large customers like this switch now is probably a good thing. They'll create some increased demand that will require increased capacity to the grid while individual users will likely take much longer to switch (even aside from resistance to switching, a lot of people buy and drive used cars and there just isn't the availability of discounted used EV's right now).

      Even if the electricity being used is generated via

      I had more of an impact to my electrical bill with getting ductless ac for my home, then with my electric car.
      Being that the most postal workers will drive 20 miles for a days worth of work, at slow speeds. EV energy usage is probably going to be much better than most people fear. We don't need 70kwh battery packs to charge, but smaller batteries that need less energy. As well most of the areas the Grid is actually more robust then you would think, especially as they would plug in during non-peek hour. However Post offices could also put in Solar panels for additional savings and support to the grid.

      • ductless ac for my home, then with my electric car.

        This is a very good point, and especially in places in the US where you have homes that are easily decades, many times even a century old of how much energy leakage happens. The way new model homes are built and insulated and with modern AC and heating systems are worlds apart in terms of energy needed to maintain livable temperatures in any season.

        Also while we are in the summer air conditioners get all our scorn but it gets glazed over how much energy is expended during winter where individual homes are

        • Is a heatpump really that much more efficient?

          I thought they barely edged out burning gas directly on site.

          • by jacks smirking reven ( 909048 ) on Wednesday July 20, 2022 @03:59PM (#62719958)

            Heatpumps are way, way more efficent in providing heat than burning gas. They have a heatin coeffcent of 2.0 - 4.0 depending on type and conditions. Burning gas while above 90% efficent are by nature performing at less than a 1.0 coefficent in terms of performance because heat pumps are moving energy as opposed to using it to directly create heat.

            Heat pumps are also getting a lot better at maintaining that efficency at colder temperatures which has generally been the downside, they lose efficency as outdoor temperatures drop but a lot units today would be far more efficent for 80% of days during winter seasons.

            There are a lot of sources out there to back this up but the always good Technology Connections on youtube has a great little series on on it that is worth cehcking out: Heat Pumps: the Future of Home Heating [youtube.com]

      • I asked our mail person, and for this small town post office the shortest route is 20 miles, the longest 75. Even if the longest has to stay gas, the other 4 could be electric.

        The catch is how do the electric trucks do with chains on in the winter? But in general mail delivery is nearly ideal for an electric vehicle.

      Everybody won't be charging their vehicles at the same time. My car knows about the beginning and end times of the lowest rate, and the start time varies depending on how much energy will be needed. Some cars will charge at the beginning of the period. Is it a problem in Norway yet?

      Utilities will gain a large amount of extra revenue, a fraction of the immense torrents of money currently going to gasoline and diesel, to upgrade the grid. Nearly all studies show extra revenue exceeds extra costs up to a

      If the grid can't stand USPS having some EVs, there's really not much hope for anything. It's not a large proportion of vehicles in the USA.
    • by DanielRavenNest ( 107550 ) on Wednesday July 20, 2022 @04:04PM (#62719974)

      If all light vehicles in the US converted to electric, it would increase total annual kWh about 20%. If the conversion takes 20 years, then grid capacity needs to increase 1% a year. In the last 12 reporting months (to April 2022), utility capacity grew 2.9%. So we have it covered.

      The reason capacity has grown more than 1% is solar and wind have generally lower "capacity factors" (their actual average output divided by rated capacity). Grid-wide demand is 41.6% of installed capacity. This allows for peak daily and seasonal demand, plus a reserve for plants that are not producing for whatever reason. If most vehicles are charged at night, that just means the plants that can run at night will be used more. Demand at night is typically half of daytime, so there is plenty of extra plant and grid capacity at those times.

        Very encouraging statistics. On the other hand...

        "The governor [Newsom of California], a Democrat, ordered an analysis of the events that resulted in blackouts during a pandemic. He also moved to reduce demand and increase power supplies by asking consumers and businesses to use less electricity and ordered the California State Water Resources Control Board to produce more electricity from dams under its control." And "As triple-digit temperatures blanketed the West on Aug. 14 and 15 [2020], the California

  • Since most USPS truck do about 20-30 miles in a day, recharging won't take much time, but what they really need is chargers that will stagger the overnight charging, to minimize the peak load.

    • Since most USPS truck do about 20-30 miles in a day

      A couple people have made this statement in this thread - do you have documentation? I went looking but was unable to locate that information.

      However I did find that the longest postal route in the US is 181.4 miles [usps.com].

      (No agenda is intended behind the question... I'm just curious)

      • "Just asking questions", eh?

        The average postal route requires 24 miles of driving and nearly all of them are less than 70 miles. Current technology can therefore easily satisfy USPS requirements for EV deployment, as evidenced by foreign posts and private companies already making that transition.

        https://postaltimes.com/postal... [postaltimes.com]

        I think this was also addressed in the enormous document the post office made for the vehicle selection process but I can't find it now.

        • Thanks! Given that I found that "longest route" on USPS' website, I figured the average route length should also be there; but it appears I was wrong.

          Just based on my gut feeling, I would think the amount of time postal vehicles spend idling every day is also a good argument for moving to EVs.

          • Oh definitely. It's like the dream scenario for EVs. All routes are known, lots of idling, stop and go, short trips, small overall route distance.

            It's absolutely idiotic that they didn't go with a 90% EV fleet. Even a stock Transit EV could could just almost cover that longest route, let alone a custom EV.

    • Simply limit the total draw on the charging circuit so they take however many hours the vehicles will sit idle.
