Energy Efficiency
• 2006: An Energy Saving Plan was launched.
Objectives 7% and 6% in specific consumption reduction in natural gas and electricity.
Planned activities were:
−Metering, Controlling,
−Training & Communication,
−Standardization,
−Investment plan and Waste reduction plan.
Tenaris Dalmine steps for energy efficiency.

•2009: A global Energy Efficiency Plan was launched in Tenaris, also creating an R&D
department for Energy Efficiency.
The crisis “Help” ENMA to implement a new program oriented to reduce Energy losses, thanks to:
−New Courses
−internal inspection program
−A first standardization of operating procedure for reduce energy consumption, mainly during a non production period.
−A first step of Compressed air reduction plan has been conclused
−Tenaris Dalmine receives external recognitions:
-10.000 “Titoli di Efficienza Energetica TEE” (1 TEE= 1 ton of oil saved) have been assigned by the Italian authorities for the main high technology investments.

•2010: Joint activity between Dalmine and Lloyd’s for
obtaining:
• EN 16001 “Energy Management System” certification for Dalmine
• Accreditation as EN 16001 certifier for Lloyd’s Register
- It was reinforced activities of audit, inspection, and opportunity identification.
- In three areas was installed new Lighting system
- Nitrogen/air conversion program has been completed

•2013: A big project of Heat recovery, based on 2 Steps, was launched.
- Installation a new HRSG in major hot rolling mill.
- Heat recovery in EAF (Electrical Arc Furnace).
Continuous penetration of energy policy in every business functions:
-Design of new lines according to Best Available Technologies
- Inclusion of energy efficiency as a criterion of purchasing components (Pumps, electric motors)
- Installing VSD to better regulate the water flows.
