This table summarizes total installed chargers by charger type in the sample of utility reports reviewed. More than 19,000 chargers have been installed, representing 37 percent of the planned totals in the corresponding approved programs. The “Approved” column only includes approved chargers associated with programs for which Atlas was able to find reporting on installed chargers. For example, for an approved program that targets 100 DCFC and 200 Level 2 ports, if Atlas was only able to find reporting on the number of Level 2 ports installed, the 200 Level 2 ports would be included in the “Approved” column but the 100 DCFC would not be included in the Approved column. This allows an apples-to-apples comparison of the “Installed” column to the “Approved” column. Project completion is calculated as the time period between a program approval date and the date of the most recent report for that program divided by the approved program term.
Atlas identified 16 utility reports that included information on the number of chargers deployed in underserved communities. Within these reports, 31 percent of installed chargers have been in underserved communities. At least six of these 16 programs are exceeding their commitments, in many cases by more than 100 percent. Table 2 summarizes the number of chargers installed in underserved communities and compares these numbers to the targets established in the approved programs. Notably, California programs make up more than 95 percent of the reported chargers in underserved communities.
This table summarizes the number of chargers installed in underserved communities and compares these numbers to the targets established in the approved programs.
Several utility reports Atlas reviewed included installation cost information. Among these reports, for Level 2 hardware and installation, utilities spent on average about $8,000 per port, with costs ranging from $1,423 per port for residential chargers in Baltimore Gas & Electric’s service territory to $17,892 per port for chargers at workplaces and multi-unit dwellings (MUDs) in Pacific Gas & Electric’s service territory. Installation costs for residential chargers were the least expensive with all three of the lowest reported per port costs coming from residential programs.
For a point of comparison, the International Council for Clean Transportation (ICCT) estimated Level 2 hardware and installation costs for public and workplace chargers to be around $6,000 per port, about 25 percent lower than the average from the utility reports reviewed2. Level 2 costs were highest in California, with an average reported cost of $15,453 per port for non-residential chargers. Among non-California programs, the average reported cost for non-residential chargers was $7,125 per port. It is worth noting that the California programs that reported per port costs were all approved in 2016, whereas several of the programs from other states were approved more recently, ranging from 2016 to 2019. EV charging installations in the early days of the market were likely more expensive than they would be now. In addition, while Atlas aimed to only include per port costs that included utility-side make-ready infrastructure, customer-side make-ready infrastructure, and EVSE hardware, it is possible that some of the California programs included some costs that other programs or the ICCT did not. For example, the PG&E program that reported $17,892 per port included site design and it is not clear whether other programs or the ICCT included this element. In addition, across utility reports, it was not always clear whether costs such as general and administrative overhead were included. The Rocky Mountain Institute notes that these costs can contribute 20 percent or more to total costs, so if some reports included these costs and others did not, that could help explain some of the differences across reports.
For DC fast chargers, reported costs were closer to the ICCT’s estimated hardware and installation cost of about $115,000 per DC fast charger, ranging from just under $46,000 per charger in Duke Energy’s Florida service territory to $167,000 per charger in Hawaiian Electric Company’s service territory and averaging $115,000 per charger. Even excluding the $46,000, which was significantly lower than the reported costs in other programs, the average cost per DC fast charger was $129,600 per charger, not too far off from ICCT’s estimated costs. Table 3 summarizes reported installation cost data for DC fast chargers and Level 2 chargers from the sample of programs reviewed.
This table summarizes reported per port cost data found in the sample of utility progress reports reviewed. The costs include installation and equipment costs.
Stay tuned in the coming months for a new EV Hub dashboard that will incorporate all of this data and more that Atlas has collected from its utility report tracking efforts. If you know of a utility report that is not included in Table 4 at the bottom of this page that we should add to our tracking efforts, please let us know.
