Commercial district heating and Cooling:
Albena 09-05-2014
an example of high technology with conventional fuel ad biomass integration
The project
• The biggest private district heating/cooling project in ITALY
• 20.000 sm • More than 4 km
pipeline• Most advanced
technology for heating and cooling
Albena 09-05-2014
Potential growth
• The location is in the center of the industrial district of Padua
• Commercial building are its todays main customers • Plan to expand the piping and give energy to
prestigious clients such as – National research center in Padua CNR– Città della speranza (center for diagnosis and treatment
in pediatric oncology)

Energy supply
The technology
Albena 09-05-2014
Energy supply
• Heating and cooling final exchangers– Remote controlled substations that provide heating
and cooling to the customer
Economics
Albena 09-05-2014
• The Power plant is a “One to Many” model in GBE
• It is supplied by gas and extra electric energy
• Sells hot and cold water and extra energy production
• the high total efficiency in power, heating and cooling supply + italian incentives ( TEE) give high profitability to the business
WAY to GREEN
Albena 09-05-2014
• In front of the Power Plant is located the Padua waste recovery center
• It can supply Biogas from waste to Telezip CHP and bolilers
• 500 ton of CO2 can be saved in this way
• 100% Green district heating can be reached
