Maryland Superchargers: Charger Audit Results

This virtual charger audit of Maryland’s Tesla Superchargers is intended to complement my ongoing assessments of utility-owned public charging stations. The aim is to compile independent data points to evaluate charger reliability against the state’s 97% uptime target.

On October 4, 2024, I used the Tesla app to check the availability of all 531 Tesla Supercharger stalls across 59 active locations in Maryland. Each Supercharger location in Maryland has between four and 16 stalls.

Overall Port Availability on 10-04-2024: 99.1%

The audit found that 5 out of 531 Supercharger stalls (0.9%) were reported as out of order in the Tesla app, resulting in an overall availability of 99.1%.

Maryland Supercharger Status on 10-04-2024

This level of availability aligns with the consistently high reliability of Tesla Supercharger ports that I documented during the summer of 2023. During those months, we drove to hundreds of Supercharger locations across the United States. Often, we visited more than a dozen sites in a single day without encountering any problems and being able to charge on the first attempt.

Tesla Tops, BGE Flops: A Data-Driven Look at DC Fast Charger Usage Near Columbia Maryland

May 2, 2024May 2, 2024 Lanny

Fast Charger Showdown: Local Usage Trends in 2023

Here in Columbia, Maryland, I’ve been closely monitoring the usage patterns of nearby electric vehicle fast chargers since 2020. This includes a mix of CCS/CHAdeMO stations from EVgo, Electrify America, Baltimore Gas and Electric (BGE), and Tesla Superchargers. My approach is simple: I track the electricity consumption at each location by recording monthly meter readings and analyzing the data over time. The goal? To gain valuable insights into how fast charging infrastructure is being utilized in this region and identify trends in usage growth.

The chart above visualizes how much people utilized the fast chargers at four different locations throughout 2023. To understand this, I calculated the average daily usage per charger at each site. Here’s how I did it: I took the total electricity used each quarter, divided it by the number of days in the quarter, and then divided that daily usage by the number of fast charger dispensers at the site.

While all four locations saw an increase in usage compared to earlier quarters, there are some significant differences. The utilization rates and growth rates vary greatly between stations. Notably, in the last quarter of 2023, each Tesla Supercharger port dispensed, on average, more than three times the amount of electricity daily compared to the EVgo chargers. Interestingly, the BGE chargers, despite being less than a mile away from the Electrify America station, have a significantly lower utilization rate.

2023 Tesla Supercharger Expansion: A Detailed Look at DC Metro Area Growth

January 9, 2024January 9, 2024 Lanny

31 Tesla Superchargers Added in the Washington, DC Area During 2023

In 2023, Tesla made significant additions to its Supercharger network in the greater Washington, DC area, introducing a total of 31 new sites—an increase from the 19 added in the previous year.

In September, Easton, MD Supercharger opened to non-Tesla vehicles following a retrofit of MagicDocks. Annapolis, MD expanded to 16 stalls in June, incorporating eight 250 kW stalls alongside the existing eight 150 kW spots.

Springfield, VA witnessed a transformation as the original 150 kW stalls were replaced. A new 20-stall location with 250 kW stalls was built a short distance away in the parking lot.

In contrast, the Frederick, MD Supercharger at FSK Mall was deactivated in September and its status remains uncertain.

One new Supercharger location has already opened in 2024 in Owings Mills, MD. Also, three additional sites are under construction in Jessup, MD; Woodbridge, VA; and Marshallton, DE.

Jessup, MD 8 stalls, 250 kW at Royal Farms
Woodbridge, VA – Richmond Hwy 8 stalls, 250 kW at Wawa
Marshallton, DE 12 stalls, 250 kW at Wawa

New Tesla Supercharger Now Operational in Owings Mills, Maryland

January 4, 2024January 4, 2024 Lanny

A Tesla Supercharger has recently opened in the garage at Metro Centre, located at 10500 Grand Central Ave, Owings Mills, Maryland.

Featuring 12 charging stalls with a maximum rating of 250 kW, the Supercharger is conveniently situated on the west side of the 2nd floor within the parking garage.

Positioned adjacent to the Owings Mills Branch of the Baltimore County Public Library and the Metro Crossing Apartments, this Supercharger is in a strategic location in the neighborhood with easy access from the street.

The completion of this Supercharger, taking over eight months, longer than usual, might be attributed to the nationwide shortage of utility transformers.

Fast Charger Utilization – Columbia / Jessup Q4 – 2022

February 14, 2023February 14, 2023 Lanny

Understanding DCFC Usage Growth

For the past several years, I have been tracking the electricity usage at the meter of several fast charger sites in the vicinity of Columbia and Jessup, Maryland. My goal was to understand how quickly the utilization of fast charging is growing, and whether some EV charging locations are experiencing more growth than others.

The data that I have collected shows some interesting trends in DC fast charger utilization over time. To give you a sense of what I’ve found, I’ve created a chart that compares the daily electricity usage at five fast charger sites in the area. These chargers are located midway between Washington, DC and Baltimore and have been selected because they represent a mix of CCS/CHAdeMO fast charging sites and a Tesla Supercharger.

Each vertical bar in the chart represents a quarter year of the average daily kWh of electricity used per individual charging dispenser at each site. By analyzing this data, I can gauge the relative utilization between fast chargers located in the same general area. It is my hope that by sharing these findings with you, we can gain a better understanding of the growth of electric vehicle fast chargers and how they are being used in Maryland.

Charger Location Map

In October 2021, I released a Fast Charger Utilization Study about these chargers, followed by an update in January, 2022. With 18 months of data, we now have a more comprehensive understanding of how EV drivers are utilizing these fast chargers over time.

V3 Supercharger Planned for Vienna, Virginia Wawa

October 16, 2019October 16, 2019 Lanny

Drawings Indicate Eight 250 kW Supercharger Stalls

Tesla plans to build a Version 3 Supercharger at a new Wawa store in Vienna, Virginia. The location is a former Caldwell Banker building at 465 Maple Ave. (Rt. 123) at the intersection with Nutley St. Map link. Construction to convert the existing building began in September and management expects the store to open around April, 2020.

Plans show eight Supercharger stalls. Five charging spots are on the north side of the parking lot near the entrance from Nutley, Street. Three stalls are shown on the west side of the lot across from the main store entrance according to drawings submitted to Fairfax County and obtained by PlugInSites through a Virginia Freedom of Information Act request. One of the stalls will be in a pull-in spot. Two spots will be “dedicated” with “TESLA VEHICLE CHARGING ONLY” signs. The remaining stalls will allow “15 MINUTE GENERAL PARKING” according to the documents.
