PVS BLOOM TRIGGERED MW | ITALY
The triggering of 4 pilot PVPPs in the Veneto region over landfills
Thanks tothe action of the coordinator of PVs in BLOOM, Unioncamere del Veneto,among others a 1 MW photovoltaic system will be built in Noale, Venice, on the formerlandfill called C? Barbiero. After delivering of prefeasibility study by Unioncamere del Venetoin collaboration with ENEA, the project was temporarily deadlocked because offinancial shortages in the municipality.
The PVPPis being built and will be due by the end of 2011. It will have a megawatt ofpower and will be the largest plant in Italy made over a former landfill.The project, realized by the City of Noale in collaboration with Veritas (thelocal public utility), will be build with last generation photovoltaic modulesof silicon that will occupy about 3 acres of former landfill. The panels fittedwill not cause environmental pollution, nor emit electromagnetic radiation. Theplant will save 5,500 tons of fossil fuel and to avoid emissions of 11,000 tonsof greenhouse gases. The energy produced will satisfy the electricity needs of350 families in Noale.
The Sospirolo PVPP
Sospirolosaid yes to the "photovoltaic field": the aim is exploiting disusedand degraded sites to produce solar energy. The solicitation came from Unioncamere Veneto the city councilgave an acceptation. The administration charged engineer Savi to make apreliminary study to evaluate the feasibility of the project, which waspresented during the session.
“Theformer landfill has been identified as a disused area – Savi explained - whichwill be added to the adjacent private land to reach approximately 17 thousandsquare meters. 700 thousand kilowatt-hours could be produced per year,exploiting the most of usable area. But we have to consider that themunicipality debt capacity is maximum 2 million and a half euros forinvestment, so we assumed a plant producing 550 thousand kwh / year. It wouldcover the entire energy needs of the territory, which is around 440mila kwh /year, and the remaining would be sold to ENEL. Currently these installationslast 30 years. We calculated that the City will have an annual cash flow of61,409 euros with net investment and maintenance costs. The system will be paidin 10 years so the City will enjoy the profits for the next 20 years”. “If weconsider - the mayor Renato Moro adds – that Sospirolo spends about 50 thousand euros inelectricity, the profits will rise to over 100 thousand per year”.
Sospirolo takes as an example Carano in Val diFiemme, which currently have the largest public photovoltaic field in Italy. Theassumptions have been made, so the next step is to prepare the call forproposal. The company that will provide the most economically advantageousoffer - not only for the price but also for the performance and the duration ofinstallation– will take the contract. Even the political minority party isfavor for the project, but they are asking to be most involved in order to givecontribution to the initiative.
The Tiretta PVPP
Since 2000 the Tiretta landfill is considered a polluted site to be reclaimed because it polluted the wells through percolation of a substance derived from bromacile. This product is used for agricultural herbicides, and it poisoned wells in Quinto di Treviso; those wells are still closed by union orders, but we are finalizing risk analysis of the landfill in a few months. This work is arranged with Treviso province and Arpav. In the meanwhile, Arpav analysis certificates are showing a worsening situation determined by release of contaminants found in wells downstream.
I remember that exceeding just one parameter it implies the prosecution of reclaim.
The Tiretta landfill, thanks to the support and action of Unioncamere del Veneto, will have a new future. Of course it will never become a place to bring our children to play, but at least, and it is not so bad, it will be "inoffensive" and for free. A project for safety and requalification of the Tiretta landfill was officially presented: by Paese city and will be partially funded by the Veneto Region, and designed by Priula Consortium and by ENEA.
The innovative aspects of the operation mainly concern technology and economic-financial self-sustainability of the operation.
Tiretta, considered one of the most polluted landfills in the Veneto region, will be covered by a new impermeable layer A photovoltaic park will be build on it, not using traditional panels, but a film with cells able to capture sun's rays. The film will always remain adherent to the waterproof surface, and will consequently change. This technology has been used for the first time in Texas, and it will debut in Italy only in Paese, in the Veneto region.
According to the prefeasibility study drafted by Unioncamere del Veneto, keeping in account the urgency of carrying out a safety measure intervention on the landfill, and the need to reduce consistently the leakage of leachate, making the landfill safety is possible through an intervention with a temporary (20 years or similar) geomembrane capping, allowing to dilute the costs of the intervention by the municipality in possibly 20 years. This will allow the municipality to recover its coffers condition putting away the income that will be created starting from the end of 2012 since the turn of the key of the PV plant saving the money for the definitive capping operations.
The technology used will be the one proposed by UNISOLAR, as in the case of the three pilot experiences of Tessman, leppe and Malagrotta monitored by PVs in BLOOM.
The project will initially be funded by the Veneto Region. 7 million euros coming from the regional government will have to be repaid in 15 years at zero rate, and 388 thousand euros will be received in free grants. The City of Paese will give the money to Priula consortium that will manage the work. The photovoltaic system will produce the resources needed for the return of 7 million euros to the Region, through the sale of produced energy and with the FIT.
Furthermore, thanks to production, and adding income taxes, it will also be possible to support the final capping intervention in 2034, when a new vegetable soil will be put on the landfill. The work is safe even if contributions will be cut. In that case, the waste rate would be increased slightly, but sharing among the municipalities managed by Priula, the raise will be about 0.46 cents each family.
Energy production could already start in 2012.
The Roncajette PVPP
The plant has been installed on the landfill of Roncajette, in the Municipality of Ponte San Nicolò (PD). After the involvement in PVs in BLOOM of the Basin Consortium of Padua2, contacts were taken by Unioncamere del Veneto with the competent regional offices dealing with the various phases of the authorization procedure. Meetings with the three main DGs of the Regional Government in charge of the bottleneck passages of the authorization procedure have been organized, in order to sensitize regional officers on the theme of functional re-covering of marginal areas through PVPPs, which, as in the case of Roncajette, can be considered a class of installations that retain special consideration by legislators and administrative officers given their potential impact in terms of land re-qualification and valorisation of resources. The situation was unlocked in May-June 2009 and the authorization was awarded on the 24th of June. Good relations still continue with the Consortium of PD2 that will act as testimonial for other implementations during the next reporting period, in Italy and in the other involved countries.
The triggering of 9 pilot PVPPs in the Sardinia region over various typologies of marginal areas for a total of about 11,843 MW
Municipality of Ozieri - On the Chilivani Industrial Area has been build a PV plant of 2,634 MW by the Sorgenia Solar srl. The municipality has called our agency to confirm the decision of Sorgenia Solar to implement the PVPP Plant in the Industrial Area. The authorization through a SUAP to build a PV plant have been concluded also with the support of our agency, in the framework of PV in Bloom. Support consisted in local procedures suggestions about soil characterisation. Project has been developed by Sorgenia Solar with which there is a continuous contact and information exchange on local technical and administrative solutions. Plant has been realised into September 2010 and linked to electric grid the 8th of September 2010. This plant was sold to a financial company the 3rd of August 2010. PEPS engagement it was also to realise and give to the community, for free, the pre feasibility study.
Municipality of Tempio Pausania, 1,056 MW (two linked plants of 528,12 kW each one), on the industrial area. Autorization was asked in November 2009 by B. Energy srl, it is finished in November 2010 and it was linked on the electrical grid the 28th April 2011. The Energy Agency supported the community in the same way of the other communities and , in addition, through the local so called “service conference”. It is necessary to underline the difficulties emerged during the authorisation process period, regarding the lack of awareness of procedure by public officials at all levels. This is an important problem for the companies for investing in the area.
