1. Scope Of Work

As a designated consumer, Tata Power Co. would like to carryout Energy Audit of

Paras Thermal Power plant Akola under the notification received by BEE dated 27th

May2014. Paras Thermal Power Plant has installed capacity of 500 MW and

comprises of two units having 250 MW (each) coal based fuel power plant

The audit of each unit will be carried out separately but under the same defined

scope. Heat Rate and Unit auxiliary consumption are the two main parameters of

the power plant which represent the health of that plant. Hence Auditing agency

shall *

1, Assess thorough tests, the potential available to improve Thermal and electrical

energy consumption

2. Suggest specific measures to reduce Thermal and electrical energy consumption

over a period of time with techno commercial viability.

3. Audit the major equipments, auxiliaries and include fact findings, assessment of

equipment and loss levels, performance measurement and analysis, suggestions

for improvement of performance parameters over a period of time, maintenance

improvements, operational performance, raw material improvements and strategic

planning.

4, Preparation and submission of report within 20 days after collection of data in

the format specified in the BEE notification.

5. Use the Calibrated instruments with the valid certificates for analysis and to

eliminate any doubt on the measurement
