PV plant in Campardo Landfill how to put together several municipalities in a joint project PVPP linked to the lighting systems Alessandro ing CHIES Veneto Municipality Reference Group Valencia, 07 September 2010
The group of municipalities • CIT – Consortium for the waste management – www.bacinotv1.it • Born in 1983 • Joins 44 municipalities • All the north of Treviso provinceVeneto Region
The main idea • CIT Manages a medium landfill which is in post-mortem state. • Building a PV system on the landfill can be an interesting bussiness activity for the consortium. • A choice: one single big plant (1-2MW) managed and owned entirely by the consortium or…
... the cooperative choice • Divide the landfill in several parts and build 40 to 50 PV plants < 20kWp each. • Each plant will be owned by one of the associated Municipality • The incentive tariff is always maximum (PA exception for the incentive tariff). • The CIT collects the incentive tariff, the municipalities owns the energy.
The landifll • 39.549 sqm • Status:post mortem • Very lowpolluted liquids • Very lowmethane production
The PV power plant • 50 PVPP up to 20kWp each • Low voltagegeneration • One singlegrid injection point • One single power transformer
The PV power plant • Panels disposedin order to leaveaccess to thepumps and wells • Proper southorientation • Poly-Si standard technology
The incentive tariff for 2011 • Giving the ownership to the municipalities, will gain the maximum incentive tariff for that size of PVPP (always integrated - financial law 2008). • The 20kWp is the best trade off between the size of the plant and the value of the incentive tariff.
The power utilization • Public lighting system was abandoned for several years. • The state of the art is much ahead compared to the state of the lines… • Introducing LED, LEP and alhogenuric lamps can decrease significantly the amount of power required.
The new lightning system • LEDs or LEP based • Very high efficiency (>100 lm/W) & Very long life (>50.000 hrs) • Smart dimming (with no human presence light will be reduced to up to 80%) • Digital communication and remote monitoring on optical fiber in the pipes. • Advanced vibration monitoring (giroscope) for ground movements detailed sampling
Join the strengths • Electric energy production during the day and injection into the grid at the maximum energy value; • Use electricity from grid for lighting during the night when its cost is very low; • PVPP of 20kWp can provide energy for up to 200 LEDs street lamps (SMART DIMMING, SMART LIGHTNING).
Specific benefits • The Public Administration always has the higher PV incentive tariff (for that class of plant size) • +5% in incentive tariff if in landfills thanks to the actions of PVsInBloom • +5% if the plant is owned by a small municipality (<5000 citizens)
Specific benefits • +20% if the owner of the plant will provide to the grid manager the quantity of energy injected the next day with an uncertainty of up to 10%.
Business model • CIT makes completely the investment (this help the municipality that cannot invest so easily now (stability pact); • Cit will keep entirely the incentive tariff (in this way will obtain 0.377 + 5% + 5% = 0.4156 instead of 0.314 + 5% = 0.3297 €/kWh
Business model • The municipalities owns the energy thanks to a law that allows for the municipalities to inject power in a site different of the utilization one.
Cash flow • A single 20 kWp PVPP has this incomings:
Business return • A single 20 kWp PVPP has this cash flow:
Business return • Budget indicators on a single 20 kWp plant:
Business breakeven • The breakeven of the investment is: 8 years
Conclusion Thanks for the attention
