Tamakuha,

DisttWest Champaran, Bihar


2/31

A Non-Govt Organization registered in 2007

under the Societies Registration Act 21, 1860

Based in Patna, Bihar

Funded by NRIs as well as local residents


3/31

MissionEmpowerment of remote and neglected

rural areas of Bihar through spread of

Energy and smart Agricultural practices

Goal for the project

To provide clean electric lighting to thehouseholds in Tamkuha at a rate cheaper

than their current expenditure

Site Selection

UP on 3 sides and the erratic Great Gandak on the fourth


5/31

Populationapprox. 1200 excluding migrants + athriving marketplace with over 50 shops

No. of householdsapprox. 350

Distance from distt. Headquarter - ~150 km

Distance from electrical substation82 km

Distance from nearest railhead47 km

Paddy production of over 1200 tonnes/year

Site Selection


6/31

Technology

Has to be non-conventional

Solar energy is expensive

Approx. Rs. 400 / W for installation

Wind energy is not amply available

Hydel power is not feasible

High cost of establishment Approx. 7 km from the nearest river

Biomass energy is practically the only available option


7/31

TechnologyBiomass Gasifier

TechnologyBiomass Gasifier

Dual Fuel Mode - Very Commonly Used

Single Fuel Modewe are the first using rice-husk

Generator

Gasifier

Total CostRs 10,00,000 *

*We teamed up with new suppliers for the gasifier and the generator

with govt approved suppliers the cost is over Rs 25,00,000

our system is cheaper even without the govt subsidy

Operating Expenses

Approx. 50 kg Rice-husk / hour

One LPG cylinder per 4 starts

3 personnel Misc. expenses on maintenance of the

system

Power Distribution


14/31

Power supply for 6 hrs in the evening

Pre-paid power at the rate of Rs. 30 per 15-20 W CFL forhouseholds and Rs. 40 per 15-20 W CFL for businesses Only CFL allowed for lighting

Total 300 connections

Avg. less than 2 CFL per connection Approx. Rs. 50 per connection

Approx. 65 A electricity usage at 210-220V (As read at the plant) Approx. 15% distribution loss

Solution


19/31

Setup a mini Rice mill in partnership with a local at the plant Milling capacity of ~400 kg paddy per hour using approx. 15 A / phase

Milling at zero cost to attract consumers Operation and depreciation cost to be recovered by sale of the bran

Approx. Rs 10,000 per month (Rs. 4000 organizations share)

Operate the dehusker and polisher alternatively Possible to operate in parallel with the electricity supply to users

Generation of ~300 kg rice-husk per day

Daily consumption is approximately the same More than 40% rice-husk generated assuming 6 months operation of the rice mill

Cost of setting up the rice mill ~ Rs. 70,000 Organizations share Rs 35,000

21/31


Removing the need for LPG

Store the Producer Gas for usage during

the next start Storage at ~200 psi

Less than 10% leakage in 24 hours

Adds Rs 10,000 to the cost

Fuses with every connection to check extreme theft of power Not aware of any efficient circuit breakers for 20 W power range

5-volunteer Gramin Urja Niyantran Samiti formed to check the power

theft as well as the regular fulfillment of operators responsibilities

Entire village divided in 4 sectors and 2-volunteer teams formed toassist in timely collection of advance dues Not an easy task

Need to generate more revenue to keep the operations fairly

independent of collections from the users

Power Distribution - Monitoring


24/31

approx. 30 A current in one phase still remaining Run a 3 hp water pump for irrigation

Compare Rs 30 per hour vs Rs 80 per hour for 5 hp pump sets

Approx. Rs 3000 per month for 5 months

Adds Rs 15,000 to total investment

Working to add a wheat grinder to the rice-mill Possible because only the dehusker or the polisher of the rice-

mill run at one time

Would add Rs. 15,000 to total investment (7.5K in partnership Would add approx. Rs. 5000 per month in earning (Rs 2500

being the organizations share

Further Improvements


25/31

Winter Economics

Total ExpenseRs. 12,500 pm

Collection from the usersRs 15,000 pm

Income generation from subsidiary activities ~ Rs. 7000pm (very very conservative projection )

Net saving of approx. Rs. 9,000 pm

Daytime operation expected to commence in january Primarily for irrigation and operation of the rice-mill / wheat

grinder

May expect an additional income of approx. Rs. 9000 pm


26/31

Expect the demand to grow 100% Rice-mill wouldnt operate

Revenue of Rs. 30,000 from evening operations

Expect at least as much load as winters during the day Revenue of approx. Rs. 15,000

Opportunity for catering power to threshers

Operations cost approx. Rs 25,000 pm A saving of over Rs. 20,000

Need to store husk for the rainy days Ample space (over 4000 sq feet) land for stocking

Ample husk in the area currently We have verbal contracts with over 6 rice-mills in the area for 100% of their rice-husk

For the Summer

So Far

Total Investment of ~11,00,000 Including Rs. 25,000 in maintaining operations in the initial

months

Conservatively projected savings of Rs. 15,000 pm

averaged over a year

Carbon credit cash from European Agencies worthapprox. Rs. 50,000

Return of more than 20% p.a. System pays itself off in 5 years only


29/31

Future

Extend the concept to at least 25 villages

in the rice-rich region in next 2-3 years


30/31

Roadblocks

Political boundaries

Has to pass through UP to reach thisunfortunate region of Bihar from Bihar

We dont know of a legal way to transportgoods through the BiharUP and UPBiharborder

Need fundsa lot of it

Seeking help from banks, investors anddonors
