Unified automation and accurate process controls contribute to better overall process management of the Salmisaari power plants

Metso will modernize the automation and field instrumentation at Helsingin Energia’s Salmisaari A and B power plants in Helsinki, Finland. The investment will ensure high availability and safety at the plants long into the future. In choosing the supplier, the company emphasized overall best value for money and fulfillment of tight technical requirements.

New automation will replace the existing automation system from 1984 at Plant B, which produces electricity and district heat, and the system from 1986 at Plant A, which produces district heat. In the future, the plants’ main fuel of coal will be replaced with pellets that will account for a 5 – 10% share at first.

“By utilizing modern control methods, it is possible to reach better process control,” says Heikki Mylläri, Sales Director, Automation, Metso.

Metso’s extensive turnkey delivery will consist of two Metso DNA automation systems, field instrumentation, a safety interlocking system, replacement of programmable logic controls, field engineering, an emissions reporting tool to meet present directives, installation, testing and commissioning. Modernization at Plant B is scheduled to start in May 2014 with startup in September 2014. Plant A will be modernized in 2015.

The order is included in Automation’s first quarter 2013 orders received.

Metso has earlier delivered automation to Helsinki Energia’s Kellosaari backup power plant, Salmisaari coal storage inside a cliff and water treatment, which all will now be integrated into the new automation. The entity will utilize the reporting system earlier supplied by Metso. In the future, all power plants and processes will be operated from the same control room with uniform user interfaces.

As one of the largest energy companies in Finland, Helsingin Energia supplies electric energy to about 400,000 customers in Finland and covers more than 90% of the heat demand in the capital city with district heat.
