Energy Efficiency 2006 a strategic choice! Why?

Energy is a third component of TenarisDalmine product cost, after Raw material and Labour. Reduce energy costs was essential to ensure the competitiveness and business sustainability at TenarisDalmine.

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.



•2007: A 120 MWe high efficiency Combined Cycle Power Plant started the

operation to self-production of electricity, steam and hot water both inside and outside the plant (district heating).

Energy Efficiency Tenaris Dalmine steps for energy efficiency.



•2008: The first high efficiency combustion system has been installed in a

reheating furnace. (45% methane saving)




•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




•2011: New regenerative burners has been installed in a major Rotative fournace.

Decrease of Natural Gas specific

consumption (20% methane saving)

•Decrease of consumption during non operative period




•2012: April 2012 Tenaris Dalmine & CTE got the ISO 50001 certification.

As conseguence of EnPI analisys, a new program of pump systems efficiency improuvement has started.

At Tenaris level was written “BAT” - Best Available Tecnologies – in order to define “Optimal way» for every specific application

Continuous Improvement Groups (GMC) methodology was structurally applied to energy management.




•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.




•2014: May 2014 Dalmine Obtained the ISO 50001 certification for all the Italian

sites.

•Closed 12 Continuous Improvement Groups in energy consumption reduction

•And Now??

•Looking for some big investment (difficult in terms of return of investment)

•HRSG in a major hot rolling mill will start up at the and of 2014

•Heat recovery project in Steel Shop (EFER) is on going

•Optimization of energy use thanks to implementation of strong EnPI, audit, inspection, new Continuous improvement Groups
