Castellalto is a town of 7,500 inhabitants in the province of Teramo, in the Abruzzo region. The municipality is part of the mountain community of Vomano, Fino and Piomba. The capital is located on the top of a hill, in a panoramic position, along the ridge between the Tordino valleys and the Vomano Valley.

The lighting system serving the municipality of Castellalto uses an electrical power of about 540 kW to power 1,423 light points. The requirements for the system were as follows:

• Electricity supply
• Ordinary and extraordinary operation and maintenance of public lighting systems
• Regulatory adaptation works and technological upgrading of systems through the use of high-efficiency light sources
• Management and control equipment and components that allow energy savings to be achieved in compliance with EU directives

The plant redevelopment project consisted of:

• Restore the safety of the operation
• Ensure greater energy efficiency (installation of high-efficiency lamps, use of flow reduction panels, installation of photovoltaic sources)
• Ensure a suitable management service, thanks to a remote control system
• Enhance the aesthetic and environmental impact of the public lighting system

• Scheduled and predictive maintenance based on the computerization of public lighting systems
• On-call and emergency service
• Energy saving, with the same lighting performance, which makes it possible to amortize the costs of redevelopment and compliance interventions
• Greater safety of the systems, thanks to a capillary survey of the condition of each individual light point
