standby power and energy efficiency
DESCRIPTION
The key initial objective of the workshop is to go through the key steps in ensuring a reliable power supply to critical systems using various available options. The solutions can vary from the simple diesel generating set as standby sources to high-capacity UPS systems for large business premises. New technologies such as fuel cells have matured and are fast becoming mainstream solutions. Of course, all this comes at a price, which means that the solution must match the actual needs at a reasonable cost. We will discuss how to save dollars by finding the right solution to your needs so that you invest just what is needed and where it is needed. Another major aspect is to ensure that critical power supply is itself very reliable. This will need suitable redundancies and a well-engineered multi-module system so that when the need arises the redundant modules cut-in and take over the load without any hitches. This workshop will also briefly look at the design issues involved in planning the distribution of critical power by deploying state-of-the art control devices such as static transfer equipment. Finally, strategies you can implement to optimise energy efficiencies at your facility will be examined. Reducing electric power usage results in reduced expenditure to the consumer. On a macro-level, it reduces power demand and avoids the need for power cuts and load shedding by the power supply agencies. It also reduces the capacity requirement and capital expenditure on standby power equipment. The workshop is concluded with the steps to take to optimise the energy efficiency of your installation. If you are responsible for maintaining power availability in your facility, this workshop is something which you simply cannot afford to miss. And all you need is to just invest three days of your time and listen to what our expert instructors have to say!

• Conventional energy sources– Involves a combustion process– Depletion of natural resources like coal, oil, etc.– Major Air Pollution contributors
• Non conventional/Renewable energy sources– Combustion process not a must– Use Sun, wind, etc directly to produce power– Bio degradable wastes also can be used– Air pollution is avoided
Energy Sources

Global Energy scenario
• Modern society today critically dependent on energy for its development
• Overrate of production and consumption of energy causing permanent damage to our natural habitat
• Measures are to be adopted by all sections of society: the government, utility companies, industries and individuals
How to contain waste, preserve the environment and stretch the inventory of current energy resources, until alternative renewable and more sustainable sources of energy are developed
• Energy efficiency :
