Automation retrofit: Green energy production in southeastern Finland

Metso will increase the reliable supply of hydroelectric power at the Inkeroinen and Anjalankoski power plants owned by Kemijoki Oy in Finland by renewing the automation in their four water turbines. The deliveries will take place in the spring and autumn 2012.

The deliveries will take place in the spring and autumn of 2012.
Due to its control characteristics, renewable, clean hydroelectric power offers a superior backup for the reliable supply of electricity and can also help manage sudden disturbances. The reliability of the turbine and its automation plays an important role in electricity generation. Three turbine logics at the Inkeroinen power plant and one turbine logic at the Anjalankoski plant will be replaced by a Metso DNA automation system, which will be used to manage, control, protect and optimize the water turbines. Metso will provide the system with updates and versatile services well into the future to support the investment life cycle.
"Metso is a strong player in the area and has local staff available," explains Janne Ala, Power Plant Manager, Kemijoki Oy, about the decision to choose Metso as the supplier.
Kemijoki Oy is Finland's most significant producer of hydroelectric power and related services. The company owns 20 hydroelectric power plants of which 16 are located on the Kemijoki River water system area, two on the Lieksanjoki River and two on the Kymijoki River. Of those on the Kymijoki River, the 17 MW Inkeroinen hydroelectric power plant was built in the 1920s and extensively renovated in 1994. The 20 MW Anjalankoski power plant was built in 1983. Both of them supply electricity to the national grid. The total capacity of Kemijoki Oy's power plants exceeds 1,000 MW.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
