Problem, Opportunity,and Solution

The Problem: Nepali Energy CrisisGovernment imposed a daily 16-hour electricity blackout starting November 2008; this is a protest march of electric 3-wheeler taxis rendered useless. Load-Shedding is projected to continue for at least next 10 years.

Inadequate Electricity Supply with Limited Scalability Results in Band-Aid Solutions

Energy Supply and Demand in Nepal

2009 2010 2011 2012 2013

Peak Load (MW)

Demand

Supply

Country’s Total Peak Demand: 800 MW;Country’s Total Capacity: ~500 MW;~100 MW of New Power Plants Underway, but Takes 4-5 Years to be “Online”

Band-Aids:• Daily 16-Hour Blackout• Horde w/ Inverter/Battery• Diesel Generators

.. which is not enough, meaning..

People set alarm for 2 am so they can iron their clothes

A family is without any water for 3-4 days since water pump doesn’t run

Businesses have to reduce hours of operation, specially at night

Even those with diesel generators not better off since fuel supply is not certain

Why Not Solar? Conditions are Great!

• Nepal in Prime Solar Area• Average 5 Sun hours/day • 5.5-6.0 Kwh/m2/day

(World leader in Solar Germany gets 2-3 kwh/m2/day)

Big Opportunity to Serve Urban and Commercial Sector

• ~50 Solar Installer Companies in Nepal;Almost All Focus on Rural because of Subsidies

• Energy Demand Higher in Urban/Commercial –Yet Completely Underserved

• IF Solar Available at Price of Diesel, Big Opportunity to Serve Those Buying/Considering Diesel Today

Large Scale PV Installations

How Does Solar PV Work?

Typical Solar PV Installation is on Roof

Sometimes Also in Open Yard Area

Parking Lot Installations Common for Businesses

Large Scale Solar Power Plants becoming more Common like this one in Germany (10 MW)

Solution: Solar as Complete Power Alternative with Costs Less than Diesel Generator

• For typical single family urban Nepali home:

• 1-2 kwh/day production• Lights• TV and Computer

OR ½ HP Water PumpOR Household Applianceslike Fridge, etc.

• For typical multi-familyurban Nepali home:

• 3.5 kwh/day onwards• Lights• TV and Computer• 1+ HP Water pump• Common Household

Appliances (Fridge, Rice Cooker, Iron, etc.)

• For retail stores, officespaces, warehouses

Challenges: Myths, Cost and Technology

Eradicate Nepali Myths on Solar with Facts

Myth #1:Solar only runs lights, can’t power heavy equipments

Fact:Only constraining factors for solar are the size of inverter and

the total surface area available to install solar panels

Myth #2:In winter, solar water heaters become completely useless! How is Solar going to generate electricity when it’s so cold?

Fact:Solar PV Technology has nothing to do with temperature.It only needs sunlight to produce electricity, not the heat!

Batteries Make Off-Grid PV More Expensive

Per-Watt Subsidies and Net Metering Needed to Reduce Costs

Problem: On-Grid Assumes “Always-On” Grid

Possible Solution: AC Mini-Grid

Suggested Research Topic for IOE Center of Energy Studies

Summary

• Energy Crisis in Nepal = Opportunity for Solar for Urban and Commercial Sector

• Solar must be Available at Price of Diesel to Compete in Large Scale

• Needed

– Awareness: Runs heavy equipments, doesn’t need heat

– Policies: Subsidies, Net Metering

– Technology: Reducing Battery Costs (“AC Mini Grids”)
