Electrify America Will Be 100 Percent Solar-Powered By 2023 (arstechnica.com) 80

An anonymous reader quotes a report from Ars Technica: One of the best things about electric cars, other than their power trains, immediate torque, and relaxing quiet, is the fact that as the electrical grid becomes cleaner, so too does every EV that uses that grid to charge. That process took a step forward this week with the news that by next year, the Electrify America (EA) charging network will be entirely offset by solar energy.

On Wednesday, EA signed a 15-year agreement with Terra-Gen to purchase electricity from a 75 MW solar farm being built by the latter in San Bernardino County, California. The Electrify America Solar Glow 1 project will break ground later this year, and when it's fully operational in 2023, it should have an annual energy production of 225,000 MWh. That's more than enough to account for the annual energy use of the EA charging network. In fact, EA says that as of April, its electricity is already 100 percent renewable thanks to purchases from various suppliers, but with the commissioning of Solar Glow 1, the charging company should have complete confidence that it's putting more solar energy into the grid than it uses to charge our cars.

    Electrify America installed their 200th charging station in November.

    Tesla at the end of 2021 had 3500 charging stations in the US, with more than 31,000 individual chargers available.

      Per Wikipedia :

      Electrify America is an electric vehicle DC fast charging station network in the United States, with more than 730 charging locations and over 2,438 individual charging units as of March 2022.[1]

      Those stations are usable by our non-Tesla EVs, also.

          We have a lot of Chargepoint chargers around here as well. Wikipedia says they have 174,000 chargers.

          Electrify America has far fewer locations, but some are very strategic. For example along I-5 in California, they are the only significant player for fast chargers other than Tesla. We started driving EVs in 2012s, and lack of fast chargers along I-5 was a very perplexing problem, which is now thankfully resolved.

        In Europe anyone can use many Tesla chargers. They are opening them up to other vehicles. They aren't cheap and the very short cables mean people have to park at some interesting angles, but still...

        I guess they aren't doing it in the US because they use a proprietary connector. In Europe they have to use CCS, it's required by law the same way mobile devices must support USB charging.

        • by madbrain ( 11432 )

          Nice. We don't have that regulation here, unfortunately. California decided to stay out of the way in this respect. Many early EVs, like the Nissan Leaf, don't support CCS, also. There is no adapter to charge a Chademo vehicle on CCS or Tesla charger. Many chargers that support CCS also have Chademo plugs, though.

          A lot of charging stations on Chargepoint are just level 2, and thus much slower. Electrify America is all CCS, as I understand.

        Indeed. Focusing on "purity" rather than net emissions is silly.

        Not burning X tons of natural gas during the day because you have solar panels is just as good as not burning X tons of natural gas at any other time, including at night.

        Actually, it is better. Demand for power is higher during the day, so marginal generators which emit more CO2 are online. At night, the marginal producers shut down and a higher percentage of power comes from wind, nukes, hydro, and the most efficient gas turbines.

        So people installing a home battery system for the sake of "purity" are making things worse.

    They are offsetting their non-solar power usage with the power from this plant. They can, after all, still provide charging services when the sun is not shining. That is mostly due to the availability of carbon-based energy sources at night, though some other non-carbon sources are in the mix, too.

    We still have no realistic means to provide grid-level storage for intermittent sources of energy such as wind and solar. Until we do, we will always need another source to make up the shortfall when the intermittent sources are not producing.

    • by PPH ( 736903 )

      It would theoretically be possible to have charging stations throttle back or cease charging if the solar source isn't available. But I don't know how many drivers will put up with waiting the extra time for the sun to come out.

      • If EVs are denied reliable charging, more people will stick with their gas cars.

        • by PPH ( 736903 )

          Well then, that charging won't be anywhere near 100% solar. It still depends on thermal, nuclear or hydroelectric sources with which to interchange energy. Particularly when most EVs charge at night.

          • Well then, that charging won't be anywhere near 100% solar.

            Who cares? The available solar power is still being used for something else, such as making toast.

                The options being discussed are:

                1. Store excess power in batteries to use later.
                2. Feed excess power to the grid to use now.

                The net emissions are LOWER for #2 because you don't have the battery charge/discharge losses (but you do have transmission losses), and daytime power is generally dirtier than nighttime power.

                But more importantly, the COST is MUCH lower for #2, which means you can afford more panels instead, offsetting even more emissions.

I don't know what kind of regulation you expect to make that happen.
