In China, road lighting represents a significant area of energy consumption and operational costs. Traditional lighting systems, such as high-pressure sodium lamps and mercury lamps, are energy-intensive and expensive to maintain, making them incompatible with current energy-saving and emission-reduction policies. To address these issues, many local governments and enterprises have adopted Energy Management Contracts (EMC), collaborating with Energy Service Companies (ESCOs) to promote energy efficiency and reduce operational costs through innovative approaches.
The following explores the application of two primary EMC models—Shared Savings Model and Outsourcing Energy Management Model—in China's road lighting industry.
In the Shared Savings Model, the ESCO bears the entire upfront investment, including equipment procurement, installation, and maintenance. The client and ESCO share the savings achieved through reduced energy costs, allowing the ESCO to recover its investment and earn a profit. This model is particularly prevalent in energy-saving retrofits for road lighting.
LED technology, with its high energy efficiency, long lifespan, and low maintenance costs, has become an ideal replacement for traditional high-pressure sodium lamps. In Shared Savings EMC projects, ESCOs upgrade traditional lighting systems to LED systems for clients.
Case Study: In one municipality, the Shared Savings Model was adopted to replace all traditional streetlights with LED lights. The ESCO provided financial and technical support， The ESCO recouped its investment through shared energy savings, while the client incurred no upfront costs.
The Shared Savings Model is also widely applied in smart lighting upgrade projects. By integrating light sensors, time switches, and remote monitoring systems, road lighting can achieve on-demand brightness adjustments and energy optimization.
Advantages:
Energy Savings: Brightness is adjusted based on traffic flow or weather conditions, avoiding energy waste.
Enhanced Management Efficiency: Real-time monitoring of streetlight performance reduces fault response times.
In the Outsourcing Energy Management Model, the ESCO is responsible for the entire management and operation of the client's lighting system. The client pays a fixed fee or a fee based on energy savings, while the ESCO ensures optimal performance and energy efficiency. This model is particularly suitable for large-scale road lighting projects, especially in the public sector.
Local governments or enterprises outsource the design, installation, operation, and maintenance of their road lighting systems to ESCOs through the Outsourcing Energy Management Model. The ESCO optimizes energy usage and reduces operational costs to generate profits, allowing clients to focus on their core responsibilities.
Case Study: In a major city, the main road lighting system was outsourced to an ESCO, which took full responsibility for its management. The project significantly reduced energy consumption and maintenance costs while improving system reliability.
The Outsourcing Model allows ESCOs to take over the technical and operational challenges of traditional road lighting systems, such as budget constraints and aging infrastructure. This cooperation greatly reduces the technical and financial risks for clients.
Comparison Criteria | Shared Savings Model | Outsourcing Energy Management Model |
Upfront Investment | Fully covered by ESCO | Fully managed by ESCO |
Risk Allocation | ESCO assumes economic and performance risks | ESCO assumes operational and management risks |
Client Savings | Shared between client and ESCO | Managed entirely by ESCO |
Best Application | Small projects with limited capital | Large-scale municipal or public projects |
With China's "dual carbon" goals driving policy changes, the potential for EMC in the road lighting sector will continue to grow. Future projects are likely to adopt advanced technologies, such as solar-powered streetlights, energy storage systems, and microgrid technology, in combination with LED and smart control systems, achieving comprehensive energy optimization. Policy support and technological innovation will further promote the widespread adoption of EMC models in road lighting, offering efficient, green, and sustainable solutions for local governments and enterprises.
Through the application of EMC, China's road lighting industry can not only reduce energy consumption and costs but also make significant contributions to the country's carbon neutrality objectives.
