AboutRooftop Revolution - Unleashing Delhis Solar Potential

The report is part of Greenpeaces campaign Switch on the Sun. Thecampaign emphasizes the effectiveness of solar as an energy solution toDelhis power needs. The report provides arguments, analysis and data to theDelhi government, its distribution companies (DISCOMS) and the people ofDelhi to show why solar makes sense for the city.

What?

Within the last decade, Delhis electricity demand rose by an average 6% everyyear. From 20 billion units in 2002, the demand in all likelihood will reach over

33 billion units by 2017, a 65% growth. Given Indias growing power deficit, therising cost of power and Delhis rapidly growing power demand, it will bedifficult to maintain the current level of supply stability in the years to come.Further, for more than 70% of its power, the city relies on other states, whichplaces Delhis power supply in a vulnerable position.

Delhis current solar RPO is a mere 0.35% by 2017, much lower than in other

states. A supposed lack of available space for solar PV in the urbanized andcongested city is considered to be a barrier. However, this holds true only iflarge, ground mounted installations are considered.

This report shows that the potential for rooftop-based solar PV systems inDelhi is significant and achievable.

Viability perspective Government buildings have already reached parity

residential consumer will come only in 2018

Delhi rooftop solar market size and viability (MW)

Solar for governmentconsumers is already

viable in 2013, if projectsare bundled into

individual project sizesof 2 MW. This providesscale to the installerwho would save on

engineering,procurement and

logistics.

Viability perspective PV costs vary significantly with system size

Solar costs in 2013 for different system sizes in India

Over 50% cost

reduction per kWpinstalled throughscale from 1-4

kWp to 500+ kWp



Grid perspective The grid should be able to absorb 20% of solarpower

Grid handling capacity vs expected solar growthA per the US Federal EnergyRegulatory Commission , atraditional grid canaccommodate up to 15% of thepeak load from distributed solarPV without being destabilized,while managing load

fluctuations easily

In some countries/cases PVpenetration has exceeded15% without destabilizingthe grid. E.g. In Germanyrenewable power has madeup more than 50% of overallpower on its grid

The report assumes thatwith better forecasting andstandardized connectivityDelhis grid canaccommodate 20% of PVpenetration



Parity-driven roadmap to reach 2 GW by 2020

Roadmap

Phase 1

Immediate parity in 2013 for bundledgovernment projects

All industrial and commercialconsumers reach parity

Government and industrial type 2exhaust potential

Phase 2

Sharp ramp up in residentialcapacity due to parity

Commercial type 1 and 2 andindustrial type 1 exhaustpotential by 2018



StakeholdersSolar can be a win-win-win for all stakeholders

Save on electricity costs Hedge against increasing grid prices Additional income from power generation or

rooftop leasing Green power and/or CSR Supply security through localized generation

With strained fossil fuel supplies , the need ofcurtailing carbon emissions and rising powerdemand, solar could be a business opportunity

Better load management Grid stabilization

Energy security Low and stable power costs Creating job opportunities Green leadership Innovation and new technology push

Recommendations Instead of funding solar PV, the government shouldfacilitate it

Aggregatethe buildings andtender them out to RESCOs

Own pilotsas test-case and a

demonstration

Support solar technicalcourseson PV installations ineducational institutions

Encourage local solar

installation/ entrepreneursthrough preferential loans

Provide strong paymentguaranteesfor government

projects Set up a risk guarantee fund

for banks to lend morereadily

Support banksin developingfinancial solutions (e.g., EMIsfor solar home systems)

Analyze technical challenges Support gas-fired power

generation for balancing Provide clear and simple

guidelines, standardizedpermitting and connectivityprocedures

Support forecasting and enableutilities to manage transition
