AAA members get 10% off EVgo rates, and don't have to pay the $8.00/month fee either. Might help those who can't charge at work for free right now, especially as AAA basic membership is less than $5/month and gives you all the usual emergency road services.
Regular members don't pay the $8 fee either if they charge at least 32 minutes a month. The 10% (actually 12 % for me) off can be had by starting a charge after 8 PM. Wondering now if AAA would get 10% off the night rate?

Newmexico will finally get some charging stations.

23 out of 33 counties, probably still won't have one in range of my leaf.
Probably all be around mount Olympus, aka Santa fe, Albuquerquestand, I-10, I-25, I-40 counties and where I-20 will eventually be.

Is going to get you.

NREL, INL team assesses levelized cost of light-duty EV charging in US in 2019

https://www.greencarcongress.com/2020/0 ... elinl.html

A team from the National Renewable Energy Laboratory (NREL) and the Idaho National Laboratory has produced a detailed assessment of the current levelized cost of light-duty electric-vehicle charging (LCOC) in the United States, considering when, where, and how EVs are charged.

The LCOC includes costs associated with the purchase and installation of charging equipment and retail electricity prices, derived from real-world utility tariffs. The analysis is published in the journal Joule.

The researchers found that under the baseline scenario, the current national average LCOC in the United States is $0.15/kWh for light-duty BEVs and $0.14/kWh for light-duty PHEVs. For BEVs, this assumes a charging mix of 81% residential, 14% workplace/public L2, and 5% DCFC, and that 84% of residential charging uses L2 EVSE.

For PHEVs, this assumes a charging mix of 81% residential and 19% workplace/public L2 and that 50% of residential charging uses L2 EVSE. These LCOC values are similar to the average residential cost of electricity reported by EIA ($0.13/kWh); however, costs vary considerably (e.g., from $0.08/kWh to $0.27/kWh for battery EVs) for different charging behaviors and equipment costs.

This corresponds to a total projected fuel cost savings between $3,000 and $10,500 compared with gasoline vehicles over a 15-year time horizon). Regional heterogeneities and uncertainty on lifetime vehicle use and future fuel prices produce even greater variations, the researchers said. . . .

Brattle Group: electric power sector investments of $75B – $125B needed to support projected 20M EVs in US by 2030

https://www.greencarcongress.com/2020/0 ... attle.html

. . .A new study released by economists at The Brattle Group concludes that an investment in the range of $75–125 billion would be needed across the electric power sector supply chain by 2030 to serve 20 million EVs—the target selected for the analysis—including adding 1–2 million public chargers. . . .

The Brattle study shows the following system impacts of the growing EV fleet:

20 million EVs will add about 60–95 TWh of annual electricity demand and 10–20 GW of peak load, requiring 12–18 GW of renewable generation capacity and 1-2 million public chargers. (Over the past 5 years, public EV chargers increased by about 40% per year, a rate that must be maintained over the next decade to install an additional 1–2 million public chargers by 2030.)

Investments will likely be composed of: $30–50 billion for generation and storage; $15–25 billion for transmission and distribution (T&D) upgrades, and $30–50 billion for EV chargers and customer-side infrastructure.

Total annual gasoline savings of $12 billion/year translates to an 8.6-year societal payback period for the investment. If the value of avoided greenhouse gas emissions is included at $50/ton, the payback period decreases to 7.2 years.

The batteries installed in 20 million EVs will have up to 1,600 GWh of electricity storage capacity. They could feed up to 300 GW of power back into the grid to help integrate renewables once large-scale vehicle-to-grid (V2G) operations are viable. This V2G storage capability vastly exceeds the grid’s current and projected storage capability. . . .
