Electrify America’s progress includes:
• 105 charging sites with 465 chargers operational and open to the public;
• An additional 42 charging sites with 189 chargers which have been constructed and
waiting to be energized by utility companies;
• An additional 85 charging sites with 393 chargers in active construction;
• An additional 73 charging sites and 341 chargers with approved permits scheduled for
• An additional 179 charging sites in design and engineering;
• Total of 484 charging sites secured for Cycle 1.
From the "National ZEV Investment Plan, Cycle 1", (4/9/17): https://www.epa.gov/sites/production/fi ... ntplan.pdf
Charging stations will be located first in the areas with the highest anticipated ZEV
demand; this is based on the forecast penetration rates of ZEVs in each region and the
estimated gap between the supply and demand of charging infrastructure in those regions. In
aggregate, the Electrify America first cycle investment will aim to establish a network of
approximately 2500+ non-proprietary chargers across 450+ individual stations.
Electrify America stations will be designed to provide access by supporting multiple nonproprietary
and interoperable charging technologies to meet different needs. Level 2 AC
charging (L2) with universally accepted J1772 connectors will serve charging at long dwell-time
locations. 50+ kW Direct Current (DC) fast charging will serve ZEV needs in shorter dwell time
situations and along highway corridors, utilizing non-proprietary charging standards (CCS and
CHAdeMO). , . .
Within selected metros, Electrify America plans to build 300+ stations across five major
use cases (multi-family homes, workplace, commercial/retail, community, and municipal
lots/garages). In order to maximize the effectiveness of the network, it is important to focus on
a variety of use cases. According to an NREL report from Jan. 2017, workplace and public
charging have both been shown to significantly increase fleet-wide electric vehicle miles
traveled [Wood et al., 2017], consistent with the overall goals of Electrify America. A
deployment mix of AC L2, DC 50 kW, and DC 150+ kW chargers will be offered across these use
cases to help best meet the anticipated needs of ZEV drivers.
A high-speed highway network (approximately $190 million in capex) . . . .
Electrify America will build a long distance high speed highway network consisting of
charging stations along high-traffic corridors between metropolitan areas and across the
country, with an initial target of approximately 240 highway sites installed or under
development by the end of the first cycle, more than 150 of which are expected to be
completed. These highway sites will be present in 39 U.S. states with higher anticipated ZEV
average annual daily traffic (AADT, a Department of Transportation measure of road traffic
density on an annual basis) by 2020. The sites will be located on prominent U.S. interstates and
highways, and they have high correlation with the recently-announced EV Charging Corridors
[Alternative Fuels Corridors 2017]. Sites will be, on average, about 66 miles apart, with no more
than 120 miles between stations, meaning many shorter range ZEVs available today will be able
to use this network. . . .
In order to accommodate the call for faster charging reflected in public comments, the
chargers deployed will represent state-of-the-art technology with the fastest charging speeds
available. Stations will focus on 150 kW and some 320 kW DC fast chargers, which will also be
capable of charging 50 kW capable vehicles at a lower power level.2
Preliminary milestones for the network construction progress are shown in Table 1. Site
development for the first Electrify America stations will begin in Q2 2017, with development
initiated for all stations by Q2 2018. These first stations are expected to be completed and
operational for local community charging in Q3 2017 and for highway charging in Q2 2018.
Given long lead times in terms of site acquisition and permitting processes, the majority of the
stations are expected to be completed near the end of the 30 month cycle, from fewer than
approximately 150-200 operational stations in Q2 2018 to 450+ stations by the end of Q2 2019.
- ZEV charging infrastructure: Electrify America will focus on two primary areas for
infrastructure investment: long-distance highway chargers and community-based
metropolitan chargers. An overview of these investments is provided in Table 2.
Long-distance highway network / Community-based metro network
Number of stations 240* / 300+
Primary technologies 320 kW and 150 kW / 150 kW, 50 kW, and L2
Number of highways/metros ~35 highways across the US / 11 metro areas across the US
Approximate spend $190 million / $40 million
As we know, the number of high-speed QC sites was subsequently increased to 300 open or under development by the end of Cycle 1 (6/30/19), all are 150+kW, and "320 kW" was upped to 350kW. I didn't reproduce Table 1, but it includes all
the sites, not just the high-speed QCs. I did my best to reproduce the numbers for Table 2.
