Power Storage Solution

There Is an EXCESS of electricity

……at Night when the demand is low.

It is Consumed when it is generated……tightly coupled integration between gen and consumption, no buffer

in between

DID YOU KNOW….

PRODUCTION DEMAND

Where lies Opportunity?

• Generation quantum does not match consumption quantum.

• Market prices of electricity fluctuates and hence it is a potential threat.

• We can Sale power at Higher Cost than that of Purchased Price from different continuous or staggered time slots.

One of the Solutions:-

Disintegrating the generation and consumption by installing a buffer in between i.e. Storage.

Energy Storage Technologies

Examples

Compressed Air Energy System.

Huntorf Plant in Germany since 1978 (290 MW).

Mclintosh Plant in Albain since 1991 (110 MW).

Pumped Storage Plant. Ludington plant in Michigan (1872 MW).

Bath County in USA (3003 MW).

Purulia (West Bengal, India) – 944 MW

Baterry Storage System. Vanadium-Redox Batteryn at Osaka, Japan since 2000(3 MW).

Compressed Air Energy Storage– one promising technology in the energy storage business

Feasibility

Tangible Power Availability with Optimized Resource Option Reduction in Power Purchase Cost Flexibility of Resourcing i.e. Own Power, UI, IEX, Banking, Bilateral etc Flexibility for Consumption i.e. Consumption by TPDDL, Trading

through IEX, Bilateral or UI.

Intangible– Un served Power due to

• lack of power availability.• Grid/network Constraint

• Renewable Integration

Scalability

• Storage capacity -KW to MW

• Comprised of 3 modules – Charging, storage, Generation- combination or any one with logistics the model can be decoupled and can start diff business.

• Can be replicated almost anywhere

Repeatability

• Installation and Usage can be across the globe.

• Disintegration of charging, buffer and discharging systems can be done and used independently.

Other Business Opportunities

Container power supply to power disturbed areas and customers…..parallel opportunity to open access….

Retail business of container power supply for group housing society or micro-grid solution.

Power supply beyond licensed area at any scale anywhere.
