Tesla’s Supercharger Pricing

Tesla’s Supercharger pricing model was originally a single flat rate per kWh that applied 24/7 but varied by location. However, this approach evolved with the introduction of variable time of use pricing, which is now used at nearly 75% of Maryland Supercharger sites. This helps to balance daily station utilization by incentivizing usage during less busy periods by offering lower prices during those times. This also helps to ease queues of drivers waiting to charge which leads to a better experience.

Tesla’s stated goal is to keep Supercharger operating costs low by incorporating efficiencies of scale and optimizing utilization. These cost savings can be passed on to customers. Tesla’s operational efficiencies and time of use price incentives helps to sustain investment in expanding the Supercharger network as well as maintain reliable charging.

Public Information Act Request Reveals Weights and Measures Testing Budget

The Maryland Department of Agriculture (MDA) anticipates spending $3,370,684.21 over five years to implement testing and compliance for Electric Vehicle Supply Equipment (EVSE) under its Weights and Measures program. This figure comes from documentation released on Friday afternoon in response to a Maryland Public Information Act (MPIA) request I submitted on January 13, 2026.

The program, which is scheduled to begin on July 1, requires public EV chargers used in commercial transactions (i.e., those accepting payment) to register and pay a $150 per port annual fee. The fee is intended to fund inspections and testing to ensure accurate electricity metering, similar to how the state regulates gas pumps and grocery store scales.

Five Year DC Fast Charger Usage Trends

Since 2020, I have been closely monitoring the usage patterns of electric vehicle fast chargers near my home in Columbia, Maryland. This study includes a mix of CCS, CHAdeMO, and Supercharger stations operated by EVgo, Electrify America, Tesla, a High’s convenience store and the local electric company, BGE. My approach is simple: I track electricity consumption at each location by recording the meter readings each month. The goal of this project is to gain insights into how fast charging infrastructure is being utilized in our region and to identify real world trends in usage growth.

The graph above visualizes year-by-year utilization growth at the five different fast charging sites between 2021 and 2025. Previous posts have reported the average daily kWh per stall dispensed on a quarterly basis over periods of a single year or 18 months. I calculate the average daily throughput per site by taking the total kWh of electricity in the period of time and divide it by the number of days in the period. Then the average daily site usage figure is divided by the number of charging ports at the site to normalize the metric to allow comparison.

PluginSites Laurel, MD Supercharger Price — The peak price to charge at the Laurel, MD Supercharger is $0.51/kWh as of December 7, 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.

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.

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

January 3, 2024January 3, 2024 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.

Maryland’s Electric Vehicle Journey: August 2023 Update

September 30, 2023September 30, 2023 Lanny

Maryland EV Registrations by County 2023 — Plug-ins as a percentage of all vehicles registered in each Maryland county as of August, 2023

Electric vehicles are reshaping the future of transportation and Maryland is no exception. As of the end of August 2023, the state has 81,088 registered electric vehicles according to data from MDOT/Maryland Motor Vehicle Administration. While this number signifies substantial growth in the EV segment, Maryland has set its sights on an ambitious goal: having 300,000 Zero Emission Vehicles on the road by 2025. This target is part of the California Clean Cars Program which Maryland adopted in 2007 to reduce emissions. However, as of now, the state is less than a third of the way to meeting its 2025 goal.

About 25,637 of the electric vehicles in Maryland are registered in Montgomery County. As the most populated county in Maryland, with more than one million residents, it makes sense’s natural that Montgomery has the greatest total number of plug-in vehicles. In August, 2021,PlugInSites compared Maryland Plug-In Vehicle Adoption by County measuring the percentage of all vehicles registered in each county that are electric. The findings were telling: Montgomery County and Howard County had the highest percentages of EVs, with 1.61% and 1.63%, respectively.

Montgomery County Leads in Total EVs

Montgomery County has the most total EVs of any county in Maryland with approximately 25,637 electric vehicles. As the state’s most populous county, home to over one million residents, it’s no surprise that Montgomery County has the highest total number of plug-in vehicles.

There were about 5 million vehicles registered in Maryland as of June 30, 2023 according to MVA. About 796,365 are registered in Montgomery County. About 18,096 of the vehicles in the County are Battery Electric, up from 8,140 two years ago. and 7,541 are Plug-In Hybrids, up from 4,623 in 2021. This is a total of 25,637 plug in vehicles now registered in Montgomery County. That means 3.22% of all vehicles registered in Montgomery County are plug-ins, more than double the 1.61% registered two years ago. Howard County now has the highest percentage of plug-in vehicles in Maryland at 3.28%. Montgomery and Howard are way out in front of the rest of the Maryland for percentage of EVs.

Anne Arundel, Frederick and Baltimore City are next in the rankings with between 1.82% and 1.36% of all registered vehicles being electric.

Tesla’s Overnight Supercharging Price Update in Maryland: What You Need to Know

Tesla Supercharger price per kWh Maryland — The peak price to charge at the Hanover, MD Supercharger is $0.50/kWh as of September 25, 2023

Tesla drivers in Maryland woke up to a surprise this morning as the electric vehicle maker adjusted its Supercharging prices overnight. The Supercharger prices in the state have been adjusted, with some stations getting more expensive to use, some getting cheaper, depending on the time of day, and some locations have pricing that stays the same. In this blog post, I’ll break down the changes in Tesla’s Supercharger pricing in Maryland as of September 25, 2023 and provide you with the latest pricing details and insights.

Understanding Tesla’s Supercharging Pricing

Tesla has historically employed a straightforward approach to Supercharger pricing, offering a single, 24/7, rate for charging that would change based on the location. However, this has been evolving, with some Superchargers implementing variable pricing structures based on the time of day. The aim behind these changes is to encourage EV drivers to charge during off-peak hours, reducing the strain on the grid and to spread out utilization in order to serve more customers.

Variable rate pricing can segment the day into as many as four distinct periods, each with its own price per kilowatt-hour. This approach tends to reflect the varying costs of electricity throughout the day, but also might be driven by Tesla’s attempt to ease crowding at Superchargers and shift more utilization to less busy times.

Maryland’s Supercharger Price Shift

In Maryland, a total of 52 Tesla Supercharger locations have opened to date. Among these, 34 have maintained their existing single daily rates or peak-time rates. For these stations the main pricing remains unchanged.

However, 16 Superchargers in Maryland have seen an increase in their peak and all-day rates, with changes ranging from an increase of $0.01 to $0.10 per kWh. Two sites in Maryland saw the peak rates go down slightly.

Off-peak pricing for Superchargers in Maryland generally went down with the recent price change. For instance, the peak time (noon to 8:00 pm) rate at the Towson, MD Supercharger increased from $0.41 to $0.44. However, the morning off-peak time (4:00 am-noon) decreased from $0.20 to $0.18.
