Due to the advantages of LED bulbs with reduced energy consumption, relatively low maintenance frequency, and long life, many cities in the United States have been promoting plans in recent years to convert traditional bulbs such as high-pressure nano lamps and mercury lamps into LED bulbs. Shakopee, a city in Minnesota, also plans to switch to LED streetlights by the end of 2018.
Shakopee, a city in Minnesota, USA, plans to switch all 1,500 street lights in the city to LEDs by the end of 2018. The engineer responsible for the project, Christian Fenstermacher, estimates replacement costs of $600,000. However, after completion, energy and maintenance costs will be saved by $100,000 per year, and replacement LED street lights are expected to last for 20 years.
In addition to cities in the United States, in St. Catharines, Ontario, Canada, from November 2015 to May 2018, the local government promoted plans to convert 93% of the city's street lights to LED lights. It cost $7.15 million, but it has begun to pay off in terms of energy conservation.
According to local government statistics, the cost of energy consumption has dropped from $2 million in 2015 to 1.19 million in 2017. As for maintenance, the annual savings of $398,000 in 2017 is more than the original estimate of 350,000. Walter Sendzik, Mayor of St. Catharines, said that the plan will not only save costs for the government, but residents will also benefit from improved lighting in the future.
