Modernization of the outdoor public lighting facilities for a period of ten years through an Energy Performance Contract (EPC).
In 2009, the Municipality expressed its commitment to sustainable
development and the creation of a new local energy model by signing the Covenant of Mayors initiative and developing a Sustainable Energy Action Plan (SEAP), with an overall goal of reducing its greenhouse gas emissions (GHG) by 21% before 2020 (compared to 2007 levels).
In 2012, a call for tenders was published with the aim of modernising outdoor public lighting facilities, including the operation of the following installations for a period of ten years through an Energy Performance Contract (EPC):
• Measurement Modules
• Operation centres
• Points of light (luminaires and crosiers)
• Connection and ground lines
The contract period included the following requirements from the service:
• Energy Management: Energy and administrative management, including a remote control system and quality control
• Preventive maintenance and inspection
• Corrective maintenance with total guarantee of damaged elements in the existing installations during the contract period
• Improvement works and renovation of facilities with high energy consumption
• Investments in Energy Efficiency and Savings
The winning bidder had to keep track of annual lighting levels, which at all times had to meet the minimum requirements of the current legislation. Annual reports should also be submitted to the Municipality about the status quo and main conclusions of the supply management, lighting levels and energy efficiency
The call for tenders was published in December 2012 and three bidders submitted proposals. The contract was finally awarded for 1,315,555 euro
Evidence of success
The Energy Service Company (ESCO) has guaranteed energy savings of 65%.
The Municipality pays a monthly fixed fee to the ESCO during the contract period. This amount is 20% lower than the quantity previously paid for electricity supply.
Less than a year after the contract was awarded, most of the corrective and maintenance actions planned had been carried out. in 2015, savings of 70% had been achieved (measured based on the audit protocol from EVO).
Potential for learning or transfer
The most significant features of this GPP approach that make it transferable are:
> Needs addressed are common among different cities.
> New facilities prevent light pollution, and reduce the production of GHG emissions significantly
> Low implementation risks
> Low risk of organizational resistance
