Utilization, Uptime, Complaints, Repairs & Profit/Loss
The first public charging station owned and operated by SMECO under a pilot program approved by the Maryland Public Service Commission is located at Leonardtown Library in Leonardtown, Maryland. This charging site has two Level 2 units in the library parking lot and opened on January 8, 2021. Site construction cost $39,385.52.
Note: This is the fourth in a series of reports of operational and financial performance data for Maryland utility-owned EV charging stations derived from various public data.
The data below reflects the activity for calendar year 2025 and includes data compiled from SMECO’s Semi-Annual Progress Reports and Quarterly Reliability Reports. The Maryland Electric Vehicle Charging Reliability Act (HB 834) of 2023 requires 97% annual uptime for each utility-owned charging port.
Site Overview
- Address: 23630 Hayden Farm Lane, Leonardtown, MD
- Level 2 Ports: 2 (SM1048 SM1049)
- Opened Date: January 8, 2021
- Installation Cost: $39,385.52
Financial
Revenue for this site totaled $938.94 in calendar year 2025. The revenue comes from EV drivers who pay $0.17 per kWh for Level 2 charging. That rate is regulated by the PSC and has remained the same since 2019. The monthly electricity bills for 2025 totaled $852.74. The main operating expenses for this site were the maintenance costs. Preventive maintenance cost $606.72 for the year and corrective maintenance cost $528.00. The yearly networking fee of $600 is based on $3,000 network costs for five years. Operations and maintenance costs for the Leonardtown Library EV charging station is almost twice the amount of revenue it took in.
Utilization
- Total Sessions: 267
- Average Energy Dispensed per Session: 15 kWh
- Monthly Electricity Usage in kWh (see table)
Uptime
Charging station uptime was above 97% except for March on port SM1048 and October on SM1049. The overall average uptime for the year was 97.4% and 97.7%. See table below.
Customer Complaints
Consumer complaints received about utility-owned charging stations are required to be reported to the PSC on a quarterly basis. Only one complaint for the year was recorded for the Leonardtown Library site. The network issue was noted to have been resolved three days later. See the table below.
Repairs
There were two repairs recorded for this station for 2025. One is described as an “EVSE component failure” that was repaired with a cable replacement on February 7. The issue was identified on December 18, 2024. The downtime duration was recorded as 73,346 minutes. Notably, the uptime for both ports was reported as 100% for the month of January.
Disconnection Events
The table below details two periods in October when Port SM1048 and SM1049 were not connected to the network. The Public Service Commission ruled that since there was no guarantee that drivers are able to initiate a charge when there is no connectivity, especially via mobile app, that these periods be counted as downtime for uptime reporting purposes.
Peak Power
The graph below shows the maximum peak power in kW for each day of 2025. The graph was prepared from an aggregation of all four quarters of session data reported to the PSC. This visualization could reveal gaps of a series of days when no charging sessions were recorded. Such instances may mean unreported downtime and might prompt further investigation. Note the shorter lines that show days where the peak is under 4kW. This likely indicates that the only vehicles that charged that day were ones that are only capable of a maximum charging speed of around 3.3 kW. Most Plug-In hybrids are in this category.
Notes and disclaimers: The presentation of this data is unofficial and best efforts are made to aggregate and portray them accurately. Consult the source reports for the official record. Some values are rounded to the nearest whole number. Where necessary, figures from Quarterly and Semi-Annual Reports have been combined for completeness.

It’s insane that the PSC can dictate pricing for these chargers that is barely above electricity costs. This is setting up a model where there’s no incentive for the utility to expand EV charging.
I’m confused as to why electricity costs are so high for a utility-owned site. Unless the site itself has significant standby electricity use relative to its use. The SMECO Level 2 charging rates are about 1.5x my home rate, so I would assume their supply rate is less than half the charging rate.
On another note and purely conjecture, I get the impression from this graph that only one or two people regularly use this site. Note the long gap in April – maybe the one regular user was away for a week or two.
