This paper presents the design of energy efficient street lighting plan and its implementation to a professional institution for optimum energy saving. Even though the initial cost to implement the plan is more, a considerable amount of energy saving can be obtained by choosing the efficient street lighting plan and energy efficient long life lamps. The design of street lighting scheme includes campus survey, selection of street lighting poles, cross arms and fittings as per manufacturer guidelines for proper illumination and energy efficiency. The optimum energy saving can be achieved by installing high power cool LED fittings. The designed energy efficient street lighting plan is suggested for professional institution and is implemented. This will help to increase the reliability of the electric supply and provides a considerable amount of savings in electricity charges.
