Tesla Supercharger Price Update in Maryland: December 2024
Tesla revised its Supercharger prices during the first week of December 2024. This update brings a mix of price increases and decreases across the state, with some stations experiencing no changes. In this post, I’ll detail the key changes, explore the factors influencing these adjustments, and provide an interactive table to help you understand the updated pricing at your preferred Maryland Supercharging locations.
Understanding Tesla’s Supercharging Pricing
Tesla’s Supercharging pricing model has traditionally been straightforward, offering a single rate that varies by location. However, this approach has evolved with the introduction of variable pricing, which adjusts rates based on the time of day. This could be to achieve two goals: optimizing grid demand by encouraging off-peak charging and improving station utilization by shifting usage to less busy periods, thereby reducing congestion at popular locations. Under the variable pricing structure, the day is divided into as many as four distinct periods, each with its own price per kWh. These rates act to spread utilization throughout the day which helps to ease crowding and aligns with Tesla’s broader strategy to enhance the Supercharging experience.
According to Tesla’s Director of Charging for North America, Max de Zegher, the company aims to keep prices low to accelerate EV adoption by passing on cost efficiencies to customers, while also ensuring financial sustainability to invest in the network and provide reliable long-distance travel options for EV drivers.

Virtual Charger Audit
In 2019, the Maryland Public Service Commission approved a pilot program allowing five utility companies to own and operate public charging stations. By regulation, these utilities must maintain a 97% uptime for their charging stations. This means each charging port must be operational and supply electricity at least 97% of the time annually.
Methodology
In September and October 2024, I conducted a series of virtual “charger audits,” using the ChargeHub, Shell Recharge and ChargePoint apps to check the online status of every charging port in the utility networks. While on-site audits are ideal, weekly virtual audits provide a practical way to track the system’s performance remotely.
Data Charts
The following charts illustrate the data collected from these virtual charger audits.

The people of Prince George’s County, Maryland may benefit from more electric vehicle charging infrastructure being installed in new residential and commercial construction, thanks to the Electric Vehicle Charging Infrastructure in Multifamily and Commercial Developments Act (CB-105-2024). The bill, which recently passed its first phase through the County Council, would require new and significantly renovated developments to include EV charging stations or “EV-Ready” infrastructure in parking lots and garages.
Key Amendments to the Bill
Initially, the legislation proposed that 20% of parking spaces be EV-Ready (pre-wired with a dedicated 40A circuit) and an additional 60% be EV-Capable (having panel capacity and raceways to support future installation). However, recent amendments reduced the EV-Ready requirement to 10%, and the EV-Capable mandate was removed entirely. Additionally, the start date for these requirements has been delayed from January 1, 2025, to January 1, 2027.
Supporting Access to EV Charging
Councilmember Wala Blegay, a key supporter of the bill, believes the legislation is crucial for making EV charging more accessible and convenient for residents. “I personally wanted to buy an EV but frankly didn’t because I saw there were limitations on where I could charge.”
Ensuring Charging Station Reliability
A key provision of the bill is the EVSE Maintenance Standard, which places responsibility on property owners to maintain EV charging stations in “good condition in all respects, including the functioning of equipment” ensuring that equipment remains functional and reliable—a growing concern in EV infrastructure.

Acredale Community Park – Pepco EVsmart Charging Station
Pepco manages an EV charging station at Acredale Community Park in College Park, Maryland, with four Level 2 chargers. As of October 10, 2024, all four have been offline for nearly six months. EV drivers have been unable to use this site—which opened two years ago—due to what Pepco describes in their semi-annual report to the Public Service Commission as “communication issues.” Filed on August 1, 2024, the report notes that the “location requires troubleshooting.” This prolonged outage, which appears to have an easy fix, has left EV drivers frustrated and ratepayers—who funded these stations—feeling deprived.
