Al-Gharraf Regional Council encouraged two projects to renew the public lighting network, which led to energy savings exceeding 110,000 kWh/year.
LEDs are currently considered a guarantee of lighting efficiency, and a safe bet considering that lamp efficiency is the amount of light emitted per unit of electrical energy (W) consumed. LEDs are energy efficient, use less electricity than compact fluorescent lamps and are more durable. The Catalan Energy Institute recommends the use of LED lights in the home to control spending and consumption, but councils are also investing in replacing old lighting fixtures to improve not only efficiency but also energy saving and economy.
In this way, the city councils of Sitges and Koppel, under the umbrella of the Graaff Regional Council and the Union Funds, have promoted two public lighting network renewal projects resulting in energy savings exceeding 110,000 kWh/year.
Improving efficiency in Cubelles facilities
Cubelles replaced the lighting points initially fitted with mercury vapor lamps and the ambient lights with new LEDs, but also renewed the old ignition system with a remote-controlled device. Replacing luminaires provides savings in electrical energy consumption, and remote-controlled devices allow astronomical ignition and automatic correction of ignition depending on weather conditions, ensuring that lighting occurs when necessary.
Total amount: €237,669.28 including VAT.
Expected savings in annual energy consumption: 371.4 kWh/year (14.2%)
Expected savings in CO2 emissions: 193.50 tons of CO2 per year (14.2%)
Improvements to Roig i Raventós Street in Sitges
As for Sitges, in recent months the municipality has improved the efficiency of public lighting installations on Avenida Roig i Raventós. The measure consisted of replacing 94 lighting points, initially equipped with mercury vapor lamps, with LED pole lamps, and replacing 66 small pole beacons with LED signals.
Total amount: €425,050.98 including VAT
Expected savings in annual energy consumption: 52,402.74 kWh/year (57.7%)
Expected savings in CO2 emissions: 27.3 tons of CO2 per year (57.7%)
But this was not the only measure led by the County Council of the Municipality of Sitges, supported by federal funds, but an important improvement in the efficiency of lighting installations in general from the plans Aiguadolç sector and the New Homes sector was also implemented. The procedure consists of replacing 113 lighting points initially equipped with 125 W mercury vapor lamps with LED lamps, and replacing a further 50 lighting points initially equipped with 250 W mercury vapor lamps with LED lamps.
Total amount: €151,539.37 including VAT
Expected savings in annual energy consumption: 59,613 kWh/year (63.5%)
Expected savings in CO2 emissions: 31.06 tons of CO2 per year (63.5%)
