Traditional street lighting systems consume large amounts of energy, resulting in high electricity costs and frequent maintenance. Without transitioning to energy-efficient alternatives, cities continue to face financial strain and environmental concerns. An Energy Performance Contract (EPC) for street lighting offers a practical way to enhance efficiency while reducing expenses.

An Energy Performance Contract (EPC) is a financing model where an Energy Service Company (ESCO) upgrades street lighting systems to energy-efficient solutions with guaranteed savings. The ESCO handles the upfront costs, and the client repays through the energy savings achieved. This method reduces financial risk, cuts energy consumption, and improves lighting quality. EPCs are ideal for municipalities, businesses, and industries looking for a cost-effective, sustainable lighting solution.

Let’s take a closer look at how EPC street lighting projects work and the benefits they provide.
