How to start Esco Project1.Esco should first conduct walk through Energy
audit.
2.The list of Encon potentials should be given to the
Client with *the equipment required
*cost of the equipment / modification
*possible savings out of the project.
*pay back period for the investment.
n To Conserve Energy for Nation through Energy
Conservation Projects in Industry with simple
cost effective ideas.
n ESCO should not only suggest Encon projects but
they should execute the Encon projects from
concepts to commissioning basis with
performance guarantee.

How to start Esco Project3.After getting this list client should decide the
priority for the project to be implemented through
ESCO.
4. ESCO should submit detailed offer for this project
with performance guarantee in terms of energy
saving figures.
5. P ayment terms/contract should be finalized on
paper with mutual understanding .
6. ESCO will design, manufacture, install and
commission the project within committed period.
While Implementing ESCO Project1. ESCO should take care of the existing
sy stem/equipment while designing and installing the
Encon modifications.
2. ESCO will have to take care of environment while
retrofitting for the energy conservation.
3. Project should be completed jointly , the end user will
have to support ESCO during project execution.
4. Project should be completed committed period
without disturbing the production.
Salient Features of ESCO module..
Responsibility of ESCO
The project installed by ESCO should meet or
exceed the savings committed to Client.
Responsibility of CLIENT.
Client should honor the repayment terms
committed to ESCO.

T here is no investment by client.
Esco to identify encon project to replace / modify
existing inefficient system.
Design,manufacturing,installation and
commissioning is ESCO’S scope during contract
period.
Contract period can de decided mutually by client
and ESCO.
Energy sa ving is shared between Esco and client
depending upon the reco very.
Esco recovers the project cost with interest and
overhe ads out of the ene rgy sa vings.
Few of the examples for ENCON projects
which can be implemented on ESCO basis.
