In 2012, A.R.I.A. S.p.A.’s activities were concentrated on the direct management of assets contributed by the subsidiaries Terni En.A. S.p.A., E.A.L.L. S.r.l., Enercombustibili S.r.l. and Ergo En.A. S.r.l., incorporated during the 2011 financial year. Furthermore, activities were conducted to coordinate and provide services in favour of the subsidiary S.A.O. S.r.l. and Ecoenergie, placed in liquidation in 2012.

At the end of April 2012 the final CIP 6/92 Agreement was signed governing the withdrawal of energy for the two new lines of the San Vittore waste-to-energy plant.

Note also that during the period the company was involved in electrical energy marketing with the Group company Acea Energia Holding, which performs market operator activities, in relation to the volumes of energy produced by the two new lines of the San Vittore plant over and above that withdrawn by the national grid operator under the CIP 6/92 regime.


Terni waste-to-energy plant

The waste-to-energy plant operates in electricity production from renewable sources, and specifically the paper mill pulp waste to energy sector.

Due to the plant revamping works which began in 2010, the waste-to-energy project was suspended for the majority of the year. The photovoltaic plant installed at the site, however, was operating regularly and in 2012 it generated 398,066.40 kWh of electricity.

Plant revamping works, already commenced on October 2010, stopped as a result of the company’s withdrawal, pursuant to Legislative Decree no. 490 of 8 August 1994 and Presidential Decree no. 252 of 3 June 1998, from the tender contract stipulated with the economic operator that was the winning bidder in the initial selection procedure. They were completed during the year and on 21 December 2012, the plant began operating in parallel with the electricity system, in compliance with the deadline pursuant to art. 24 of Legislative Decree no. 28 of 3 March 2011 for access to the incentive scheme set forth for plants which begin operating before 31 December 2012.

During the year, scheduled maintenance work performed directly by plant personnel also continued. Activities aimed at obtaining a new AIA (Integrated Environmental Authorisation) for the extension of authorised fuels were suspended based on the guidelines issued by the applicable Integrated Area Authority, which decided, unlike what was established in the initial formulations of its plan, to no longer use the Terni waste-to-energy plant for Combustible Dry Waste.


Paliano RDF production plant

The Paliano RDF production plant possesses an ordinary authorisation for the production of RDF, expiring on 30 June 2018.

This authorisation certainly represents a significant asset, especially if we consider the difficulties connected with locating, realising and authorising activities in the environmental sector, and in particular in the waste treatment sector and the lack of plants, compared to actual needs, made evident by the Administration established by the Central Government introduced with decree of the Ministry of the Environment and Protection of the Sea of 3 January 2013.

After executing updating works linked to the safety of the infrastructures serving the plant and renovating the fire safety system, completed in the first quarter of 2012, the activities recommenced previously in reduced form in the second half of 2011 resumed as usual beginning from the second quarter of 2012.

The technical details of the activities performed are shown below:

Year 2012 Year 2011
Dry waste 713 0
Dry waste from AMA tonnes 16,172 3,285
COREPLA incoming special tonnes 7,065 0
Other incoming special waste tonnes 2,742 0
TOTALS tonnes 26,692 3,285


San Vittore del Lazio waste-to-energy plant

the San Vittore del Lazio waste-to-energy plant operates in electricity production from renewable sources, and specifically from RDF.

As noted, 2011 saw the completion of the revamping project through the implementation of lines 2 and 3 of the plant, while works commenced for the complete renovation of line 1, whose activities ended in March 2011.

Therefore, Line 2, which started up in April 2011, as well as Line 3, which began operating in July 2011, were both operational in 2012.

The main operational data are shown below. The comparison with the same period of last year must necessarily take into account the circumstance that two lines were operating simultaneously in 2012, unlike in 2011 during which operations began only in April 2011 for Line 2 and in July 2011 for Line 3.

An examination of the operating figures highlights a significant increase in the quantity of RDF delivered by third parties, in addition to the quantity delivered by SAF S.p.A., and the increase in the potential productivity (MWh sold/parallel hours) of line 2 (plus 11 MWh/h), compared to that obtained previously by line 1 (8 MWh/h).

These figures allow the performance of the new plant to be viewed in a positive light.

Please recall that during the last quarter of 2011, an authorisation request was presented targeted at environmental upgrading for the architectural-functional redevelopment of the site as a whole, and the completion of civil works strictly related to the plant. At the same time, a request to renew the Integrated Environmental Authorisation, due to expire on 27/07/2012, was also submitted. The enquiry is still in progress.

In 2012, a communication was submitted pursuant to art. 29 nonies of Legislative Decree 152/2006, concerning some non-substantial changes consisting of the representation of the effective operational capacity of the plant with respect to forecast data. That proceeding closed with the Lazio Region’s issue of a Decision acknowledging the non-substantial change with the expectation of an increase of approximately 19,000 tonnes/year in the quantities that can be recovered at the plant.
