DC Area Tesla Superchargers Map 2024

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

Testimony – Maryland Electric Vehicle Charging Reliability Act

Lanny
Maryland Electric Vehicle Charging Reliability Act Testimony

Economic Matters Committee – March 2, 2023

The following is a transcript of my testimony to the Maryland Economic Matters Committee in support of the Maryland Electric Vehicle Charging Reliability Act (HB 834). The legislation subsequently passed and went into effect on October 1, 2023. This is one of the first laws of its kind in the United States.

We deserve transparency and accountability for EV charging infrastructure that’s being built with public funds.

My name is Lanny Hartmann. I’m an EV driver and a BGE ratepayer.

For years we’ve been told that public charging has 98% uptime, 99% uptime, even 100% uptime.

Last year a study was released by the University of California that looked at the reliability of the fast chargers in the San Francisco Bay Area. The study found that only [72.5%] were functional.

I had my own concerns about charger reliability so I conducted my own test of fast chargers in Maryland. In August I visited all the fast chargers owned and operated by BGE.

What I found was that 71% of them were fully functional. In other words, one out of three were broken.

For every station that didn’t work, I reported the issue to customer service.

I compiled my findings and presented them to the Public Service Commission at a hearing in September. You have that report in my written testimony.

Two months later I visited all 69 stations again. This time I found that only 65% were operational. The reliability had actually gotten worse. 

There is a wide gap between what we’re being told about charging reliability and what EV drivers are actually experiencing.

The PSC and lawmakers need quality data to inform decision making.

We deserve transparency and accountability for EV charging infrastructure that’s being built with public funds.

That’s what this bill would do.

Thank you and I ask for a favorable report.

New Tesla Supercharger Now Operational in Owings Mills, Maryland

Lanny
Owings Mills, MD Tesla Supercharger

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.

Maryland EV Registrations Surge to 92,722 by End of 2023

Lanny
Maryland electric vehicles registered 2023
Plug-in electric vehicles registered in Maryland as of Dec 31, 2023

As of December 31, 2023, Maryland has 92,722 registered plug-in electric vehicles, reflecting an increase of 29,978 in the past 12 months, according to MDOT/Maryland Motor Vehicle Administration data.

This noteworthy accomplishment represents a 48% rise, slightly less than the 51% increase observed in the preceding 12-month period from January 1, 2022, to December 31, 2022.

Goal of 300,000 by 2025

Despite remarkable progress, Maryland faces a challenge in reaching its ambitious targets. The state aimed for 60,000 Zero Emission Vehicles (ZEVs) on the road by 2020 and an even more ambitious goal of 300,000 ZEVs by 2025. Aligned with the California Clean Cars Program adopted in 2007, these goals mandate vehicle manufacturers to sell a specified number of ZEVs in the state. Although Maryland was two years behind in meeting the 2020 target, the 2025 goal remains a substantial challenge. The ongoing growth in EV registrations indicates positive momentum, but achieving the state’s vision for electric vehicle sales will require sustained exponential growth in the rate of ZEV adoption to bridge the gap. I will continue to track the progress toward these goals here on PlugInSites.

Thurmont Municipal Workplace Charging Funded by Maryland Charge Ahead Grant Program

Lanny

In a significant stride toward electrified mobility Thurmont, Maryland, has recently installed Level 2 workplace charging stations at two locations—the Municipal Office and Police Headquarters.

Thurmont, MD EV Charging
Thurmont Municipal Office – 615 E Main St, Thurmont, MD 21788

Support for EV Adoption

Convenient access to charging at workplaces can encourage employees to consider purchasing an electric car, especially those without access to home charging, such as individuals residing in apartments, condos or townhouses. Installing more workplace EV charging stations is one of the most effective ways to support the adoption of electric vehicles.

This electric vehicle charging installation was made possible through the Maryland Charge Ahead Grant Program (CAGP), an initiative funded as part of the Volkswagen settlement.

There is one single-port EV charging station located at the Thurmont Municipal Office at 615 East Main Street. A posted sign indicates that the charging space is reserved for town office staff only.

A Chevy Bolt EUV with a town emblem on the door was parked in the spot when I visited Thurmont last weekend.
