The Italian White Certificates Scheme (WhC)
• (WhC) is the most relevant scheme for promoting energy efficiency in Italy (at least 60% of the target at 2020 of EU directive 2012/27/EU)
• WhC is a scheme based on the market and it is not selective about technologies or payees
• The support scheme is based on the obligation, placed on electricity and natural gas distributors with more than 50.000 customers, to achieve a quantified target of energy savings yearly (TOE)
• Voluntary subjects: E.S.Co - Energy Services Companies, Companies with certified
energy manager o certified ISO 50001, electricity and natural gas distributors with less than 50.000 customers
• White certificates attest the achievement of end-use energy savings through energy efficiency improvement in industry, residential and public sector, and are tradable instruments
White Certificates issued only for additional energy saving

Ex-Post Consumption
Total energy saving is the difference between ex ante and the ex post consumptions, but Whcs are issued only for additional energy savings, calculated as the difference between the baseline consumption and the ex post consumption.

Energy efficiency projects: pulp & paper products
Production process
Raw materials
Pulping &
Cleaning
Paper forming section
Press section
Drying Section
Finishing operations
Paper Machine
Example of energy saving projects
• Pulping: pulper with high efficiency
impeller, that reduces the power required
for the rotation;
• Press section: «shoe press», an increased
contact surface press, that reduces the
quantity of water in the paper before drying
section, and thus the steam required;
Energy efficiency projects: glass products
Production process
Raw materials
Preparing & mixing
Melting Forming Heating
treatment (annealing)
Finishing operations
Example of energy saving projects
• Melting: revamping of the melting furnace
by brick wall replacement, thermal
insulation, high efficiency burner
(rigenerative), fluid dynamic optmization of
exhaust air duct;
• Finishing operation: high efficiency
electrical drives, variable speed drives,
variable speed air compressor unit.
Energy efficiency projects: ceramic products
Production process
Raw materials
Preparing Forming Drying Firing Finishing operations
Example of energy saving projects
• Preparing: fluid dynamic optmization of air
spray, surface thermal insulation;
• Drying: thermal insulation, high efficiency
electrical drives with variable speed drives;
• Firing: replacement of furnace, with
advanced firing control and thermal
insulation;
Energy efficiency projects: auxiliary system
• Light: replacement of light bulbs with led
lamps and substituion of light housings.
• Management system: installation of
software for monitoring and remote control.
Lighting
Air compressor room
• Compressor replacement: high efficiency
compressor unit with variable speed
• Control: software for the optimization of
the air compressed room.
