Streetlight Replacement Project
About the Streetlight Replacement Project
The goal of the streetlight replacement project is to improve the quality of street lighting in Takoma Park. Benefits of the project include energy savings, cost savings, reduced light pollution, improved reliability, and an improvement in overall quality of street light. On October 24, 2018, the City council approved staff recommendation to replace the existing streetlight with LED fixtures through the PEPCO conversion program.
Current Project Status
Lighting Maintenance Inc. a subcontractor for PEPCO is scheduled to begin the street light replacement by second week of December, 2018. The project is expected to be completed by September, 2019, weather permitting.
For the ease of installation, the replacement work has been divided between the City Ward boundaries. The number of fixtures in each City ward is, Ward 1 – 390, Ward 2 – 282, Ward 3 – 334, Ward 4 – 65, Ward 5 – 171 and Ward 6 – 241, a total of 1483 fixtures.
The work will begin in Ward 6, and then move through the wards in reverse order (5, 4, 3, 2, and 1). The contractor is expected to replace 10 to 20 fixtures per day.The City will get monthly update on the progress, and the project page will be updated periodically.
The discussion concerning the benefits of replacing the City’s streetlights began about ten years ago. The discussion has included staff presentations to City Council in April, 2015, March, 2016 and October, 2016. At the October 2016 meeting, City Council authorized staff to pursue the conversion of existing streetlights to LED technology via Resolution 2016-41. The Council Resolution directed staff and Pepco to ensure that all replacement fixtures be International Dark Sky Association (IDA) Certified, 3,000 Kelvin according to IDA requirements, and address areas that may be over lit or under lit throughout the City.
Following the Council’s Resolution, Pepco initiated a full inventory of existing streetlights to identify the light levels, type, and location of each streetlight for which the City was billed. Based on that inventory, the street lights in the City are currently 80% high pressure sodium, 9% incandescent, 6% mercury vapor, and 5% LED.
The number of each type of streetlight to be replaced:
- 776 High pressure sodium (HPS) 70 watt fixtures
- 230 HPS 100 watt fixtures
- 78 HPS 150 watt fixtures
- 104 HPS 250 watt fixtures
- 14 HPS 400 watt fixtures
- 82 Mercury Vapor 175 watt fixtures
- 247 Incandescent fixtures
In June 2018 Pepco installed test fixtures on Erie Avenue, Oswego Avenue, and Hickory Avenue. Based on feedback, a second round of testing is now being conducted on Hickory Avenue to test for both reduced brightness and a warmer (white) color. The new test installed on October 1, 2018 on Hickory Avenue has fixtures that are 2,700K set to 24 Watts; 3,000K set to 24 Watts; and 3,000K set to 19 Watts.

Project Info & Timeline
- Completion date: September, 2019
- Takoma Park’s role in project: Lead
- Departments involved: Public Works
Budget & Funding Source
The City currently pays approximately $233,000 annually for street light electricity and fixture maintenance. $180,000 is paid to Pepco for maintenance and operation, taxes, and fees; $53,000 is paid to WGL for the electricity use (100% Wind).
Based on Pepco’s calculations, the reduction in energy use and maintenance costs will result in a savings of approximately $50,000 to $100,000 annually. The overall cost of the program is expected to be $372,000 and the City anticipates a $260,000 rebate from the Empower Maryland Program. Based on the projected annual savings, the program will pay for itself in less than two years and those savings from reduced energy use and maintenance costs will carry through for the life of the fixtures.
