Manufacturing Capital

What is the manufacturing capital for A2A?

The Manufacturing Capital is represented by the real estate, infrastructure and physical means (plant, machinery, etc.) used for the production of the services offered by the company.

A2A paying attention increasing attention to the recovery of materials and to the efficiency of the networks, and an increasingly leading role in renewable energy

In 2020, investments dedicated to making the Group’s plants and networks increasingly efficient continued.
The Envinronment BU The Environment BU continued to strengthen the material recovery chain: start of the sites for the construction of the new plant for the treatment of OFMSW (Organic Fraction of Municipal Solid Waste) with a capacity of 100,000 tonnes/year to produce compost (20,000 tonnes) and biomethane (8 milllion m3) at Lacchiarella (Mi). A new plant is also being built for the production of secondary solid fuel (SSF) at the Cavaglià site that will use the waste from the sorting of plastic from separate waste collection, which cannot be sent for material recovery, and also some non-differen-tiated waste, the plant, through optical scanning, mechanical separation and shredding, produces a fuel of variable size (called Plasmix), a product useful for co-combustion in cement factories that helps to reduce the impact of CO2 emissions from the cement industry. In addition, A2A and Suez signed a Memorandum of Understanding imed at creating a player of excellence for the management of waste from the Italian production and industrial system. This operator will be capable of handling over 250,000 tonnes/year of industrial waste.

The Generation BU, for its part, has continued its investment plan aimed at the growth of renewable production, acquiring the Group's first wind farm in Campania with a capacity of 8.2 MW. In addition, it has continued its activities of safety of dams and hydroelectric plants, even in extreme hydraulic situations. Finally - in order to respond to the opening of the market for useful services to the national electricity system - A2A has decided to take the road of "electrochemical storage systems” and has initiated the authorization procedures for their installation for a portfolio of projects of around 60 MW to be built at sites it owns: Brindisi (6 MW), Gissi (15 MW), San Filippo del Mela (20 MW) and Chivasso (20 MW). The first to be authorized, in 2020, were the storage systems for Brindisi and Gissi.

The Networks and District Heating BU, finally, it has carried on the plan of interventions on the water network, among which the Aquarius Project stands out for the city of Brescia, which has seen the installation of 170 sensors ("noise logger") in the city center area - covering 60 km of water supply network - able to detect the "noise" of a leak escaping from a pipe, while 52,000 new smart water meters were installed. 

At the same time, in 2020, an intervention plan was defined to increase the resilience of electricity grids against the extreme events related to climate change: flooding, falling tall trees and formation of sleeves of ice or snow. This plan This plan led to the single city of Milan the replacement of 10,000 joints. But the plan foresees many other actions for a total investment of 20 million euro. A2A has also launched the plan for commissioning the 2G smart metering system. The start of the massive installation activities started in the city of Brescia at the end of July with a total of over 43,000 new meters replaced. The replacement of approximately 1.1 million meters will be carried out over a period of 15 years (however, massive replacement will be concentrated in the first 5 years) for a cumulative investment of 197 million euro

Water is a very valuable resource and ensuring its quality is one of our missions


In 2020 it has completed work on the new treatment plant in the Brescia municipality of San Paolo, capable of serving 6,000 equivalent inhabitants, which is fully prepared for the doubling of its capacity, since the civil works relating to the second line have also been completed. 
The Offlaga treatment plants were also completed, with a nominal capacity of 8,000 equivalent inhabitants, treated in two twin and interchangeable treatment lines, and the San Gervasio treatment plant (with a capacity of 1,200 equivalent inhabitants) was upgraded through the installation of a new modular treatment line with MBR technology. 
In February, it has began work on the construction of the Valtrompia district treatment plant, which will make it possible to overcome the problem of 

European infringements for the municipalities in the area that are not covered by the treatment service. 
The project envisages a first phase, already underway, which will allow treatment of the wastewater generated by 85,000 equivalent inhabitants, while the second phase of further expansion will be able to serve up to 138,000 equivalent inhabitants. The total investment (first phase plus upgrading) amounts to 36 million euro
Lastly, work also continued on the construction of the sewerage and water supply system for the Calvisano agglomeration, which is expected to be completed by 2023 (at the end of 2020, the project had reached 70% progress).

Brescia abandons coal as fuel well in advance: start of the first thermal storage tank

In 2020, A2A abandoned the use of coal as a fuel at the Lamarmora plant in Brescia well in advance. This decision benefits from the accelerated progress of investments already made for the construction of thermal storages and projects for the recovery of additional heat from industrial activities. 
Further investments are planned for the Brescia district heating system over the next few years, mainly in the following projects: 

  • increase in thermal storages, in addition to those already built at the Lamarmora plant, with two more systems of 2,200 m3, each with a capacity of 95 MWh, which will be built at the North plant, bringing the total heating capacity of Brescia to around 550 MWh.
  • construction of a 250 KW photovoltaic system at the Lamarmora plant, covering an area of 1,500 square metres, to power the district heating pumps and reduce.
  • expansion of the flue gas treatment system (DeNOx) at the waste-to-energy plant: a new high-efficiency system will go into operation this year to further reduce nitrogen oxides, which are already well below legal limits 
  • recovery of heat from the fumes of the neighbouring waste-to-energy plant: activation of the first line in the 2021 heating season and expected completion in the 2022 heating season.
