WHY Tri-generation

Leaders in Energy conservation & Environment preservation

Co-generation and Tri-generation

Global experience & Technological advancements By:

Vikas Tripathi Head – Marketing Cooling Business


Tri-generation/Cogeneration

A new concept?

Reliable? Viable? Sustainable?

Who uses Co/Tri-generation… and Why?

How do they do it Globally?

What is happening in leading economies? ( Cogeneration

Perspective)

How are regulators & other shapers shaping it?

What are the Challenges?


The first public electricity supply in

the world was the cogeneration

system implemented by Edison in

1882 to supply electricity and steam

to Manhattan, New York, later

converted to a tri-generation system

which is now the eighth largest

decentralised energy network in the

world.

Concept is Not New

Reliable, Viable & Sustainable? Users can tell better

And many more…


“A unit energy saved by a user is greater than a unit produced as it saves on

production, transmission & distribution losses”

What is the Need


WHY Tri-generation

• Waste heat is used for generating

– Hot water / steam for space or process heating

– Chilled water for comfort cooling or process cooling

– SYSTEM EFFICIENCY UPTO 85%

Northern Region contains some of the Europe’s biggest countries

including the leader in CHP Denmark

Denmark, Finland & Sweden – Limited support for fossil fuel CHP as

large focus is towards renewable & low carbon solutions

Belgium & Germany- Has shown convincing promotion of CHP, Good

support mechanisms in place

District Heating applications incorporating cogeneration is dominant in

Eastern region

Policy Perspective

China

Announces massive tri generation action plan to achieve the following

targets:

2015: 5000 MWe through trigeneration

2020: 50,000 Mwe including 30,000 MWe of gas fired to replace

coal

Policy Perspective


Shapers of Tri-generation

Regulators

Gas Companies

ESCOs Financial

Cos.

Technology Innovators


Beneficiaries of Tri-generation

End User

• Pays only for what he consumes

• Gets reliable power & cooling supply

Government

• 30-35% T&D loss elimination

• Demand Side Management

Gas/CHPC Companies

• Predictable gas supplies

Without a doubt, Decentralised energy generation is most efficient


Hurdles & Challenges

• Supply side: Distribution Network for Gas

• Lack of incentives to make gas based power generation viable

• Lack of special gas pricing for power generation through CHPC/Tri-

generation route

• Weak Rupee- Costlier import


Technology Developments

• Shale Gas estimation of 6.1 tcf in 3 out of 26 sedimentary basins

• Horizontal fracking technology development will help in reducing shale

gas prices

• Triple Effect Absorption chillers (with a COP 1.9) can provided 575 TR

of Cooling from a 2 MW engine (30% more than Double Effect )

chillers

Conclusion

• Tri-generation is more than a century old and is most efficient solution

for thermal energy utilization

• Europe, Japan, Korea and China have embraced this solution

supported by policy framework and support mechanism on fuel price

• Many of Indian industries have suffered after investments in Tri-

generation technology due to steep rise in gas prices and still highly

subsidised power

• India needs to overcome supply side and fuel price challenges for

proliferation of Tri-generation


Suggestions

• A great initiative like this summit needs time-bound action plan for

technology and concept promotion

• Tri-generation to be focussed as part of PAT scheme and incentives

should be attractive enough to overcome supply side suspicions

• A steering committee should be formed for sharing advancement in

technology

• A draft in line with “White House Executive Order on CHP” should be

prepared with 10 years vision
