ENERGY RESOURCE: RENEWABLE OR NON-RENEWABLE
Energy Resource, by definition, must be:
Abundant and Accessible,
Reliable,
Predictable,
Technically Feasible,
Economically Competitive,
and
must have
Net Positive Benefit over its Life Cycle.

Renewable: Rainfall/Snow Melting
Just Rainfall is not a Hydro Kinetic Energy Resource. Wind blowing at 6 m/s 24x365 is not a
Wind Energy Resource. Rainfall in US & Indian S-W Monsoon are different.

WATER RESOURCE & HYDRO KINETIC ENERGY RESOURCE : P V3
Renewable: Tropical Monsoon
Tropical Monsoon Regions: (indicated in blue).
Monsoon in Indian Subcontinent is special because
of Great Himalayan Wall in the North.S-W Monsoon brings 3.5 – 10 m rainfall in 60-120 days
almost in equal measure year after year: an opportunity.
Sorry, Cannot help Boundary Distortions
This Map tells many things, which need urgent recognition

Case of : Western Ghats of Peninsular IndiaThe Unexploited Opportunity
What experts say:
“Though the west-flowing rivers draining the western aspect of the Western Ghats have substantial run-off, the spatial scope for their wider utilization is limited.” [3] But no more.

• Usable Rainfall: 4.5 m out of 7.5 m with 0.6 runoff;
• Duration of Stabilized Flow: 45 days minimum;

• Gross Flow: 70000 m3/s @ Usable Head: 1 MPa;
• Gross Hydro Kinetic Power: 70 GW;
• Gross Energy Available: 75 TWh/year;
• Practical Realization of 2% of 75 TWh Energy Potential
will deliver annually: 1.5 TWh of useful energy;
with a decent CUF: 0.123 to 0.37 (45 – 135 days);10/10/2014

Western Ghats (WG): Way Forward
• WHAT IT IS: 1.5 TWh/year with CUF=0.13-0.37
• HOW IT COMPARES WITH WIND IN INDIA[1]:
• In 2012 : 14623 installed MW actually delivered
16428 MU or 16.428 TWh at 13% CUF.
• WG are equal to 10 % of Indian Wind Energy.
• Higher the CUF better the economics, but
we need to carefully work it out.
• HOW TO DO IT: Check Dams with
Temporary Storages and
• Multiple Turbine Units10/10/2014 8© Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US)

do not ‘dam’ them, if you can avoid.

Extrapolation by Sane
Changing Paradigms:
• Can Renewables stand on own Legs? NO & YES.
• Distributed Generation and Consumption Model;
(If desirable, is this enmeshed in our thinking and planning? This is going on for a
decade).
• Moving away from age old ‘Hydro Electric Power’ Mind-Set; US has started the trend [2, 3], Poor Nations will need 50-100 years more, cannot just shut down existing plants.
• Innovating Power Extraction Devices for fully confined finite flows;
• Total Water Management Concept: Empowerment of the People and Environment

Total Water Management Concept: a citizen’s charter
must envision and ensure that
• Empowerment rather than Displacement of Humans, Flora and Fauna, as they are primary stake holders.
• ‘Distributed Generation & Consumption’ Model: Only Excess Energy & Water to External Consumers & 24x7 electricity in each hospital/school/house.
• Prevent Soil Erosion; Generate Fresh Soil Areas through Temporary Storage Hydraulic Structures: Check dams/bunds: Help Ground Water Recharging
• Use of Innovative & Appropriate Strategies: Forestation, Herbal Plantation, Grass patches, Agricultural Ponds.
• Ensure Water for Drinking, Sanitation, Irrigation and Traditional Industry for the population, tribal included.
• Generate Revenues and Create Jobs Locally and Manage Locally at Village Level.

Pilot Case Study: Resource PotentialCA near Sangameshwar (Maharashtra)Catchment Area: 15 x 2.4 = 36 km2.Height AMSL: Kondbhairav (360 m); Nivali (180 m); Nayari (80 m); Hedali (40 m); Total : 320 m.
PROPOSAL FOR IMPLEMENTATION:IT WILL NOT COST MUCH.
10/10/2014 17© Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US)
Kondbhairav Pilot Case Study: Resource Potential
• Catchment Area = 36 km2;
• Rainfall Intensity : 4500/6000 mm in 90 days
• Average Cumulative Stabilized Flow in the last 1 to 1.5 km of catchment zone with runoff coefficient of 0.72 = 15 m3/s;
• Usable Head: 20 / 320 m in Last 1 to 1.5 km
• Flumes: b = 2 m, w = 4 m, d = 1.25 m to ensure V = 3 m/s.
• LPTs: l = 3.2 m, s = 0.75, Rated Power = 16.7 kW @ V = 3 m/s.
• 30 units in 1000 m to generate 500 kW for 90 days.
• Energy Delivered: 1.1 TWh/year.
• Decent CUF of (90/365) ≈ 25 %.

Kondbhairav: Pilot Case Study:
Techno-Economic Assessment
• @ INR 4/kWh: Annual Revenue per MW: INR 8.8 million.
• Indirect Revenue of ‘Value Addition’:
- ‘Total Water Management Model
• Estimated Annual Revenue per MW: INR 10 million.
• Payback Period: 5 years
• Limit Capital Costs to: INR 50 million/MW.
• Practically Feasible, but site specific.
• Cheaper Compared to Solar by 100%.
• Cheaper Compared to Micro Hydro by 150 %.
• Prima Facie a Practical/Doable Proposition

Conclusions and Recommendations
• A scientifically sound, practically feasible,
sustainable, environmentally & socially
friendly and commercially competitive scheme
to identify, design-develop and exploit
potential Hydro Kinetic Renewable Energy
Resource Sites, wherever these wait unnoticed.
This renewable will have a net positive
benefit.
• Appropriate Power Extraction Device concept
demonstrated in March 2013.
• Support urgent Implementation10/10/2014 20© Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US)
Conclusions and Recommendations
• Most of the nations in the tropical monsoon
region are not rich and are in need of
Affordable Solutions.
• India should lead from the front to
develop this technology.
• The numbers generated are kept
sufficiently conservative so that the
conclusions remain valid under all
possible uncertainties.

Remarks
• Power extraction devices, for Wind and Tidal, operate
in similar singly confined infinite flow domains. But
devices for rivers and canals operate in fully confined
finite flow domains and must look different.
• I consider this sufficiently fish friendly as compared
to conventional rotary ‘choppers’.
• This can be a Value addition to existing Hydro
Electric Power Installations.
• Floating debris is an issue but not insurmountable, so
also sealed bearings operating in muddy water.

Tasks ahead …..
I look forward to this gathering to take up
some of the challenges to get the Technology
Details in place: Resource Development &
LPT Technology: ‘pocket belts’, ‘bearings’, ‘rotary/linear
generators with water gap’, ‘composite blades’, ‘debris removal
robots’ to name a few.
• We cannot change the way Sun shines or the way Wind
blows or even the way it rains but we can somewhat
change the way water flows from hill tops to oceans and
let the rivers flow……… ….

EpilogThis has been SIX years effort of one individual.
March 24, 2013 was first time in the world that
a classical ‘LIFT’ based Linear Power Turbine
was demonstrated in the water efflux of Tata
Hydro Power Station at Bhivpuri near Karjat
(Maharashtra). Evidence about the effort it took to
reach there can be found in the storm water drain
canal near NCC office and Hydraulics Lab in IIT
Powai campus even today.
