The document provides an overview of a presentation on sugar cogeneration and public-private partnerships in India. It discusses India's energy needs and resources, outlines a build-own-operate-transfer model for sugar cogeneration projects, and analyzes the technical and financial feasibility of potential projects at various sugar mills based on their operating parameters and fuel availability. Real-time integrated analysis of sample projects is presented, including heat and mass balances, capital costs, revenue projections, and financial analyses.

8. PP MODEL BASICS…….
 BOOT – BUILD OWN OPERATE
TRANSFER
 ITS GIVE AND TAKE MODEL
 CPMPLETE TRANSPARENCY
 ADMINISTRATIVE / TECHNICAL HELP
 ACCURATE MEASUREMENTS
 TIMELY DOCUMENTATION

9. COGEN / TRIGEN DEFINED
 Cogen is Simultaneous generation and use of electricity and heat
 Tri Generation is simultaneous generation and use of electricity , heat ,
and cooling
 Both far superior in efficiency as compared to independent generation
 Should be used where all forms of energy are required
 ITS LIKE CO-EDUCATION –SAME TEACHER
( ENERGY)

10. PPP - BOOT ISSUES
 POLITICAL WILL
 ADMINISTRATIVE / BEUROCRATIC WILL
 LOCAL MILL BOARD WILL
 INVESTORS WILL
 PROJECT DEVELOPERS WILL
 PROJECT VIABILITY- FUEL / PRICING

11. PPP- BOOT MODEL:
 Operates its own sugar plant
as usual
 Invites Project developer to
setup cogen project
 Give designated land-lease
free of cost
 Gives Free water
 Gives Free Bagasse
 All legal
 Commits to set up cogen
 Does technical & legal deligence
 Brings all capital at its own cost
and risk
 Gives power & steam free for mill
operations
 Provide capital for mill
modernisation/capacity
enhancement
 Gets all legal clearances
The Mill The Project developer

12. PPP- BOOT MODEL:…cont..
 Allows Connectivity to system
 Agree on mill modernisation-work as
well as costs
 Terms if steam/power norms not
followed
 Pass Board resolutions as per need
 Agree on concessation period,
revenue sharing/royalty on cane
crush
 Complete project development
including design, order, erection
and commissioning
 Procures balance of fuel
 Share revenue as per agreement
 Operate plants to optimum
capacity
 Hands over the plant to mill at
ZERO COST after concessation
period
The Mill The Project developer

13. BOOT ISSUES CONT……

22. BASIC SUGAR PLANT DATA

23. BASIC RANKINE CYCLE
 There are four processes in the Rankine
cycle, each changing the state of the
working fluid. These states are identified
by number in the diagram to the right.
 Process 1-2: The working fluid is pumped
from low to high pressure, as the fluid is
a liquid at this stage the pump requires
little input energy.
 Process 2-3: The high pressure liquid
enters a boiler where it is heated at
constant pressure by an external heat
source to become a dry saturated
vapor.
 Process 3-4:
The dry saturated vapor expands through a turbine, generating power. This decreases the te
 Process 4-1: The wet vapor then enters
a condenser where it is cooled at a
constant pressure and temperature to
become a saturated liquid. The pressure
and temperature of the condenser is
fixed by the temperature of the cooling
coils as the fluid is undergoing a phase-
change.

35. ADVANTAGES TO SUGAR PLANT
1. The Cooperative Mill gets complete power plant at ZERO cost
2. Mill gets modernized in terms of power & Steam consumption
3. Plant gets reliable power steam –Improved quality and better
efficiency
4. Improvement in crushing capacity –improved revenues
5. Additional revenue by way of sharing/Royalty on cane crush
6. Improved Pollution Control with ESP
7. Employment to Local people
8. Better returns to cooperative members
9. Other biomasses used- revenue to farmers
10. Environment protection – as crop residue may not be burnt

36. SUMMARY WAY FORWARD
 NEED FOR MORE CLEAN POWER IN THE COUNTRY
 RENEWABLE ENERGY FOCUS
 POLITICAL/ADMINISTRATIVE /LOCAL ``WILL`` REQD
 BOOT A WIN WIN PROPOSITION IF IMPLEMENTED
PROPERLY ..TRANSPARENCY …UNDERSTANDING
 BOOT PROCESS TO BE STANDARDISED
 FEASIBILITY ANALYSIS UTMOST IMPORTANT
 ALL ISSUES PRE DOCUMENTED & AGREED
 GO FOR IT WITHOUT LOOSING TIME
