Alcoa is continuously working to reduce energy consumption, and we have set strategic 2020 and 2030 reduction targets to drive performance among our business groups.
Our European locations reduced their combined energy intensity by 1% in 2013 compared to 2012, continuing a trend of year-over-year declines. Our six smelters, which are our most energy-intensive operations, achieved a 0.6% intensity reduction in 2013 and 4.3% since the 2005 base year. Our one refinery in San Ciprián, Spain, delivered a 1.6% decline in 2013 and 12.0% since 2005.

In June 2013, we organized the first Alcoa European Energy Efficiency Workshop at our cobalt and nickel superalloy casting facility in Dives-sur-Mer, France. Attendees from our locations across Europe shared their energy-efficiency progress and best practices.
An example of a 2013 energy-efficiency project was the upgrade of a casting unit at our Samara, Russia, location. The project resulted in a 27% reduction in natural gas consumption.
Within our framework of continuously improving our energy management, our major sites in Europe are either certified to the International Organization for Standardization’s ISO 50001 standard (energy management systems) or are working to achieve certification.
Our Lista and Mosjøen smelters in Norway, the rolling mills in Italy and Hungary, and the extrusion site in Germany are certified to ISO 50001. The refinery, smelters, and Amorebieta rolling mill in Spain, the wheels production plant in Hungary, and the rolling mill in the United Kingdom were certified in 2014. Our building and construction facility in Merxheim, France, is aiming for certification in 2015.
Our smelters and rolling mills in Spain, our rolling mill in Italy, and our smelters in Norway provide load interruptibility to their respective transmission system operator to help manage the risk of system electrical blackouts. The facilities are compensated for this service, allowing our businesses to remain operational and focused on productivity improvements to achieve increased energy efficiency and long-term financial sustainability.
