LED Lights Can Save 1600 MW


Islamabad—The replacement of conventional streetlights with that of light emitting diode (LED) lights across the country could save 1600MW, suggests a presentation on LED technology to Capital Development Authority (CDA).

Based on the projections and returns, LED lighting project is not only financially viable, but also provides additional electricity to the national grid and is in the national interest, an official said. The Capital Development Authority plans to replace 65000 conventional streetlights in Islamabad with that of LED lights that would save over 50 percent energy, he said. According to the documents, the project would reduce the CDA’s electricity bill by 50 percent.

At present, the annual bill of the CDA is around Rs1.2-Rs1.4 billion that continues to rise. The project was approved by the CDA Development Working Party comprising technical and financial experts.

The Central Development Working Party (CDWP) made a concept clearance to the project after getting a nod from the cabinet to take immediate measures for the conservation of energy in the prevailing difficult times of crisis, the official said.

In the backdrop of future energy crisis, the National Energy Conservation Centre (ENERCON), Ministry of Environment, in a letter dated January 12, 2010 advised the CDA to replace the conventional public lighting system with LED lights to reduce energy consumption.

The letter says, “We believe that the systems such as HID/LED lights can save approximately two megawatts plus electrical energy on an immediate basis in the CDA’s streetlight load.”

With a total cost of Rs6.524 billion, the CDA would spent only Rs1.631 billion on the project, while the remaining amount would be borne through less debt financing in five to seven years, the money which would be saved through reducing the energy consumption in the city after installing LED lights, according to the letter.

The LED European technology will substantially save the replacement cost of conventional lighting, as at present, the existing lights are replaced after every one-and-a-half-year on an average.
