Trigeneration means the combined production of heat, cold and electricity. Heat recovered during the production of electricity is used, partially or completely, in refrigerating machines with an absorption or adsorption cycle.

What are the advantages associated with trigeneration?

The system can meet heating requirements in winter and cooling requirements in the summer. Its degree of use is over 80%.

In addition, the potential for trigeneration concerns all regular, substantial cold consumers, whether they only consume cold (cold storage and food packaging plants) or heat and cold (abattoirs, pharmaceutical, chemical and food processing industries, office buildings and certain housing blocks).

Where has Veolia previously implemented trigeneration solutions?

In Porto, Portgual, Veolia designed, built, financed, constructed and currently operate and maintain the biggest trigeneration plant in the region, supplying heat, cold water and steam to a hospital and selling electrical energy to the grid.

The electrical power generated is around 37.5 GWe per annum, which is equivalent to supplying energy to 15,000 people.  It also produces 36 GW of heat, cold water and steam per annum and helps the hospital avoid 10,000 tonnes of CO2 emissions every year.
