Trading relations between ACEA Group companies and Roma Capitale include the supply of electricity and water and provision of services to the Municipality.

Among the principal services are the management, maintenance and upgrading of public lighting facilities and, with regard to environmental–water services, the maintenance of fountains and drinking fountains, the additional water service, as well as contract work.

Such relations are governed by appropriate service contracts and the supply of water and electricity is subject to the current market tariffs adjusted for supply conditions.

It is pointed out that ACEA and ACEA Ato2, respectively, provide public lighting and integrated water services under the terms of two thirty–year concession agreements. Further details are provided in the section “Service concession arrangements”.

With regard to public lighting, the Group provides public lighting services on an exclusive basis within the Rome area. As part of the thirty-year free concession granted by the Municipality of Rome in 1998, the economic terms of the concession services are currently governed by a service contract signed by the parties, effective as of May 2005 until the concession expiry (31 December 2027). On 15 March 2011, ACEA and Roma Capitale signed a supplemental agreement effective from the beginning of the year.

The supplements regard the following elements:

  • alignment of the term of the service contract with the expiry of the concession (2027), given that the contract is merely additional to the agreement;
  • annual update of the compensation concerning consumption of electricity and maintenance;
  • annual increase in the lump-sum payment with regard to the new lighting points installed.

Furthermore, the investments required for the service may be (i) applied for and funded by the Municipal Authorities or (ii) financed by ACES: in the first case, such works will be paid based on a price list agreed by the parties (and subject to review every two years) and will result in a percentage decrease in the ordinary fee. In the second case, the Municipality is not bound to pay a surcharge; however, ACEA will be awarded all or part of the savings expected in both energy and economic terms according to pre-established methods.

Moreover, it has been established that qualitative/quantitative parameters shall be renegotiated in 2018.

Upon natural or early expiry, ACEA will be awarded an allowance corresponding to the residual carrying amount, which will be paid by the Municipality or the incoming operator if this obligation is expressly set out in the call for tenders for the selection of the new operator.

The contract sets out a list of events that represent a reason of early termination of the concession and/or resolution of contract by the will of the parties. Among these events, reference is made to newly arising needs attributable to the public interest including that set out in Article 23 bis of Law Decree 112/2008 repealed following the referenda of 12 and 13 June 2011, on the basis of which ACEA has the right to receive an allowance according to the discounted result of a defined percentage of the annual contractual amount multiplied by the number of years until expiry of the concession.

Based on the fact that the supplementary agreement exceeds the reference thresholds set out by the Company with regard to Related Party Transactions, it was analysed by the Board of Directors and approved during the meeting held on 1 February 2011, having obtained the favourable opinion of the Committee for Related Party Transactions.


The current contract, as amended by the supplemental agreement, involves a lump-sum payment as compensation for ordinary operations, ongoing and extraordinary maintenance and the supply of electricity.

The amount accrued at 31 December 2014, calculated on the basis of lighting points as at 31 December 2013, amounted to 54.1 million euros and is billed in monthly instalments with payment set at 60 days.

The new constructions and investments contribute to the increase in the lump-sum figure due to the annual accrual calculated according to the capital allowance mechanism envisaged for the plants underlying the specific operation as well as the percentage reduction of the ordinary fee due from Roma Capitale, the amount of which is defined in the technical-economic project document.

A variable interest rate is applied to the invested capital.

It is pointed out that as a Local Authority, Roma Capitale has the power to regulate municipal taxes and duties that the Group companies are required to pay and which fall under its territorial jurisdiction. However, the Group is not solely liable for any such taxes and duties with respect to other companies operating in the municipality.

The reciprocal receivables and payables – with regard to payment terms and conditions – are governed by each single contract:

  • for the public lighting service contract, payment shall be made within sixty days of receipt of the invoice and, in case of delayed payment, the legal interest rate will be applied for the first sixty days, after which the default interest rate will be applied, as set out from year to year by a Decree of the Ministry of Public Works and the Ministry of Economy and Finance,
  • with reference to all other service contracts, the payment term for Roma Capitale as regards service contracts is sixty days from receipt of invoice, and in the case of late payment the parties have agreed to apply the current bank rate at the time.
  • for the supply of electricity and water to Roma Capitale (solely with reference to regulated market users), it is envisaged that Roma Capitale makes an advance payment of 90% within 40 days of receiving a summary list of the bills issued by Group companies. Moreover, Roma Capitale must settle the remaining balance by June of the following year. In the case of late payment for electricity or water, interest is payable to the extent permitted under the terms of prevailing AEEG provisions,
  • the prices applied to sales of electricity to free market users are in line with the commercial policies of Acea Energia. Payment terms are sixty days and, in case of delay, a default interest rate will be applied,
  • the terms of payment for the ACEA Group relating to fees for the water services concession and the rental on its head office premises are set at thirty days from receipt of the invoice, and in the case of late payment interest shall be paid in accordance with the current bank rate at the time.

The electricity sales contract terminated on 28 February 2015
