ON AUCTION: Inactive biogas power plant in Santa Maria La Fossa (CE), Via Madama Bianca 81 - LOT 4

Biogas power generation plant consisting of a concrete digester and a containerized internal combustion CHP engine, together with equipment such as pipes, pumps, trenches and storage sheds, and an electrical substation, located on Via Madama Bianca.

The unit was built on third-party land under an agreement granting a surface right over third-party land for a term of 20 years, automatically renewable twice for 5 years each, and therefore for a total of 10 additional years, unless the concessionaire exercises its right to opt out. The annual fee was set at €2,500 for the first 20 years and €3,000 per year for the following 10 years.

The plant has an electrical capacity of 100 kW and therefore a maximum deliverable electrical output of 700 kW. It consists of a single fermenter fed with livestock effluent (as well as any food industry by-products), collected in a suitably sized pre-tank created from volumes already available on the farm. The fermenter is equipped with a gas holder dome for storing the biogas.
The biogas produced is conveyed to the CHP engine to generate electrical and thermal energy, after being pre-treated for dehumidification and desulfurization, while the digestate is conveyed to the existing storage tanks for reuse as a stabilized soil conditioner for fertilizing fields. The plant is fed using effluent produced by the livestock farm next to which the plant itself was built. In this way, biomass can be moved into and out of the digester solely through underground pipes and pumps, avoiding transport by road and/or mechanical vehicles. To ensure a constant supply of biomass to feed the digester and avoid drops in biogas production, provision has also been made for a backup system for loading stackable solid material, capable of compensating for any temporary shortage of pumpable biomass caused by possible operational issues at the farm. No storage site for supplementary biomass needs to be provided on the premises, as the raw material is to be transported to the site as needed to meet supplementation and feeding requirements.

To maximize its value and profitability, it would be advisable to convert the currently inactive biogas production plant to biomethane production.

A surface right and easement were established over the plant on 31/08/2016 (registered in Naples 1 on 14/09/2016, no. 17524, Series 1T).
