Utilization, Uptime & Profit/Loss
The public charging station at the Public Parking Lot 15 in Salisbury, Maryland is owned and operated by Delmarva Power and Light under a pilot program approved by the Maryland Public Service Commission. There are two dual-port Level 2 units on the SWTCH network located in the southern end of the parking lot.
Note: This is part of a series of reports of operational and financial performance data for Maryland utility-owned EV charging stations derived from public data.
Evidence of Key Gaps
The charts below display daily charging session activity for each of the Level 2 ports at Salisbury Lot 15 for calendar year 2025. Each trace represents a single connector port, and at a well-utilized site like this one a healthy port should produce a near-continuous heartbeat of daily sessions throughout the year. The green spikes reflect days with at least one recorded session, the red flatlines indicate three or more consecutive days with no recorded activity.
The percentage figures above each segment are the monthly uptimes reported to the Maryland Public Service Commission under the Electric Vehicle Charging Reliability Act (HB 834) of 2023, which requires 97% annual uptime per port. Readers may find it useful to compare those reported figures against the session traces directly below them, particularly in months where flatlines appear alongside high reported uptime.

Financial
Revenue comes from EV drivers who pay $0.17 per kWh for Level 2 charging. That rate is regulated by the PSC. The main operating expenses are the monthly electricity bills, which totaled $4,347.91 for the year. The blended cost of electricity, calculated as total electricity cost divided by total kWh consumed, was $0.284/kWh, compared to the $0.17/kWh collected from drivers. Other operational expenses include preventive and corrective maintenance of $953.00 and $1,120.00 in annual networking fees.
