Solar energy at uniworld gardens 400kw to provide back up power ppa rs 15 kwh

Solar energy at Uniworld Gardens

400kW to provide back up power

PPA @Rs.15/kWh


Executive summary

Executive summary

  • Solar irradiation in India is one of the best in the world

  • At current prices, solar power is competitive to diesel genset power

  • Uniworld Gardens can have 400kW of roof top solar to meet ~20% of backup power needs

  • 400kW requires a capex of Rs.6 Crores

  • Free Energy can install solar power with no initial cost at Uniworld

  • Free Energy will require a power purchase agreement with Uniworld Gardens with assured offtake for 10 years at Rs.15/unit


Solar irradiation in india is one of the best in the world

  • Roof-top solar is the optimal approach to tap this radiation

  • Roof-top solar enables production at point of consumption eliminating grid losses

  • Solar power is now competitive with diesel back-up and in some regions at par with commercial power tariffs

Solar irradiation in India is one of the best in the world

Yearly sum (kWh/m2)

Optimum tilt in India varies from 10-35 degrees South

Roof-top Solar PV is cheaper than diesel power and competitive with commercial grid tariffs in some regions

Comparison of cost per power unit [INR/kWh]

Max cost

Rs.15/kWh

  • Customers using diesel powered back-up can reduce costs significantly by immediately switching to roof-top solar with battery backup

Max cost

Min cost

Max cost

Rs.10/kWh

Min cost

  • Customers paying commercial tariffs of >Rs.8/kWh can switch to roof-top solar without battery backup

Rs.5/kWh

Min cost

Diesel power

Solarpower

Grid power*

* Tariff depends on state and consumer


Solar power is however expensive and capex is the biggest constraint

Solar power is however expensive and capex is the biggest constraint

  • Solar power with battery banks costs Rs.15 crores/MW

  • Comparably diesel genset costs are of the order of Rs.2-4 crores/MW

  • Initial capex is the biggest constraint for large scale adoption of solar power

  • Free Energy has devised a solution to enable customers to pay only for the power they consume

  • Free Energy will invest the capex


How much solar power can be set up at uniworld gardens

How much solar power can be set up at Uniworld Gardens?

  • Solar panels can be set up on the roof tops of the 8 buildings

  • Total area available: 6200 sq. m

  • Solar capacity that can be set up (assuming 80% usable):400 kW

  • System capex: Rs.6 crores


400kw will generate 5 3 lakh kwh of electricity per annum

Solar will meet ~20% of backup power needs at Uniworld Gardens

400kW will generate 5.3 lakh kWh of electricity per annum


What is the free energy value proposition

What is the Free Energy value proposition?

  • Free Energy will raise the capital needed to set up these solar plants

  • Free Energy will install and maintain the solar panels without any initial capex from Uniworld Gardens

  • Free Energy will sign a PPA (power purchase agreement) with the residents of Uniworld Gardens

  • The PPA entitles Free Energy to receive Rs.15 for every unit of electricity consumed from solar panels for 10 years(genset power is at ~Rs.13/kWh and escalating at 10% p.a.)

  • Free Energy will transfer ownership of panels after 10 years to Uniworld Gardens


Next steps

Next steps

Uniworld Gardens RWA to provide in-principle approval to the Free Energy approach (initial contract to be signed between the two parties)

Free Energy will do a detailed system design to determine exact requirements

Free Energy will sign a PPA contract with Uniworld Gardens RWA

Free Energy will raise investments for the project on the PPA (2-3 months)

Free Energy will install solar power at Uniworld Gardens (1-2 months)

Free Energy will maintain the solar panel system and charge residents on a monthly basis (Rs.15/unit) for 10 years

FAQs

  • Does the solar eliminate the need for diesel back up?

    • No, solar can only substitute some of the diesel you consume.

    • Also, production is only during the day (battery bank enables consumption smoothing through demand cycles though)

    • >85% of diesel genset costs incurred every month are due to the opex (diesel consumed)

  • What maintenance do I need for these installations?

    • Free Energy provides complete O&M for the solar system

    • Only maintenance needed are: cleaning of solar panels every 15 days, replenishing water levels in battery bank every year

    • Every 5 year cycle, batteries will need complete replacement

  • What happens when there is cloudy/ foggy weather?

    • Radiation incidence on panels is lower. Therefore, lesser electricity is produced.

    • However, India is well endowed with solar radiation (refer average radiation levels) all year

  • How long will it take to install these solar units?

    • Post raising funds, these installations have 2-4 months construction lead time without any intrusion of existing power supply set up
