Effective and Efficient Method of Electricity Usage in any Institution to Reduce Electricity Tariff

C. R. Ravinthiran


The demands for electrical energy in offices, industries, educational institutes and homes are heavily increasing now a days due to the heavy use of electrically operated instruments. This increased consumption of electrical energy requires more production of electrical energy. The electrical energy production due to increased demand is not only possible to satisfy by the renewable hydro power generation in Srilanka but also need to use non-renewable thermal power generation now a days. The increased thermal power generation increases the cost for electricity production due to increasing the cost of non-renewable energy sources such as fossil fuel, coal, etc. This will increase the electricity tariff drastically in the institutions and industries. The increase of the electricity tariff is not possible to manage in most of the institutions. Therefore the need arises to minimize the electricity tariff in possible ways. This paper presents the possible methods such as the use of low energy consumed electrically operated equipment with automatic control and power management capability and the reduction of electrical energy losses and wastages from the equipment and their surroundings to minimize the electrical energy consumption in any institution and further it introduces the renewable solar energy and wind energy uses by the institution effectively and efficiently in the way of hybrid grid tie system implementation. The use of renewable energy sources provide the advantages of reducing Green Effect in our living environment as well as protecting the non-renewable energy sources from exhausting.
