We invited, the users to send technical papers on the issue given below:

"Issue # EE 02:

Variable speed drives are useful if the speed of a pump or fan is "variable". They are not always cost effective. Simpler less expensive solutions such as changing pulleys, modifications of the fan blades or a new fan, may be more effective in some cases. We are looking for people who have information and good ideas how to professionally evaluate and calculate at what "variability" a variable drive is an economical solution" has received 20 entries.

As in issue #EE01 most entries make no attempt to specifically answer to the question but talk about theoretical assessments. None of the entries provides a step by step procedure how to assess the financial attractiveness of retrofitting an existing system with variable speed drives.

It is obvious from the entries that trial and error methods are followed, which seem to be working in most cases. The project has asked Dr. Kaupp to propose a genuine approach that should be discussed among the interested parties to arrive at a common and acceptable approach. We consider this part of hands on energy manager training.

The winners are :

1. Mr. Debasish G.                     (Rs. 5,000)
2. Mr. Pandurang S. Jalkote        (Rs. 3,000)
3. Mr. K. Sathya Prakash           (Rs. 2,000)
