Energy-efficient lights to save Govt $2.8M annually
The Guyana Energy Agency (GEA) has estimated that the State will be able to rake in .8 million in savingsOfficials from the GEA installing the energy efficient streetlightsper year, following the installation of 65 energy efficient streetlights.The GEA recently replaced 65 High Pressure Sodium Vapor (HPSV) street lamps with 65 energy efficient Light Emitting Diodes (LED) lamps as part of its ongoing energy efficiency programme.The HPSV lamps were rated at 250 watts each while the new LED lamps are rated at 100 watts each. The switch is expected to lead to significantly lower energy consumption rates. Fifty-eight of the lamps were installed at Timehri, while four and three were installed at the Umana Yana and Camp and Lamaha Streets, respectively.The Government presently operates about 6000 HPSV street lamps, rated at 250 watt and 5000 lamps within the different municipalities rated at 175 watts, which accrue a yearly operational cost of approximately $653.7 million per year while consuming 10.4 million kWh of energy.However, through the use of 100W LED lamps, it is possible to significantly reduce the cost that the current street lighting systems incur. It is estimated that the 65 LED lamps that were installed will reduce the annual energy consumption by 42,705 kWh, saving G$2,800,166.85 per year. The simple payback period for these lamps is 1.07 years and the lamps have an estimated lifespan of 11 years.In order to determine which lamp was best suited for use in the pilot project, studies were carried out by GEA’s engineers. The engineers, led by Energy Engineer Leon DeSouza, were assisted by a team of Engineers from the Public Infrastructure Ministry’s Street Light Division.“We were able to determine which lamps presented the best wattage and design to meet the necessary requirements,” explained DeSouza.He continued, “The energy efficient lamps compared were 40, 60, 80, 100 and 120 Watt LED lamps and the 80, 100 and 120 Watt induction lamps. It was concluded that the 100 Watt LED lamps could be used for commercial roadways and 40 Watt LED lamps could be used for minor roads.”In keeping with its mandate to develop and encourage the development and utilisation of sources of energy other than sources presently in use and to carry out research into all sources of energy (including those sources presently used in Guyana), the GEA will continue to explore, install, and monitor energy efficient streetlight technologies with the aim of gaining knowledge and thereby make recommendations that will guide decisions with regards to street lighting.The GEA is calling on all municipalities, Neighbourhood Democratic Councils, and civic groups to take advantage of the benefits of energy efficiency by installing only energy efficient street lights.
