Metso Corporation: Metso and Fortum Heat develop a cutting-edge district heating network optimization solution Metso Corporation's press release on October 15, 2013 at 11:15 a.m. local time Accurate control improves heat delivery efficiency by decreasing heat losses in the network, and it also enables a plant to maintain optimal operation conditions during fast changes in electricity and heat consumption. Fortum's Suomenoja CHP plant in Espoo is the first power plant in Finland to optimize the dynamics of its district heating network using multivariable model predictive control. This development work builds on the optimization work carried out at the Fortum Suomenoja plant during 2012. Commissioning of the new control is planned for 2014. The district heating network in the Espoo, Kauniainen and Kirkkonummi areas is a large and complex network, consisting of the production of district heat and cooling, a delivery network, pumping stations and thousands of end users. Until now, optimal operating conditions in the district heating network have been maintained manually, and operators have had to run the network with more heat than necessary. "With the new automatic district heat delivery control system, it is possible to efficiently control the pressure and temperature of the district heating network in different parts of the network. Accurate control improves heat delivery efficiency by decreasing heat losses in the network, and it also enables us to maintain optimal operation conditions during fast changes in electricity and heat consumption. Both improvements reduce fuel consumption and CO2 emissions, making CHP production an even more environmentally friendly form of heating," says Timo Aaltonen, Production Director, Fortum Heat and Power Oy. "The new advanced optimization solution will provide district heat producers with both economic and environmental benefits through better network control. Metso has developed a performance solution that is based on customer needs and enables customers to better cope with their challenges now and in the future," says Sami Pitkänen, Vice President, EMEA Services, Automation, Metso. According to Pitkänen, Metso's control solution will benefit energy companies in all countries where district heating is a widely used form of heating, such as Finland, the Baltic countries, Sweden, Germany and Poland. Located in Espoo, the Suomenoja power plant produces heat for the inhabitants of Espoo, Kauniainen, and Kirkkonummi, and electricity for the national grid. The power plant produces approximately 1,800 gigawatt-hours of electricity and 2,200 gigawatt-hours of district heat per year. Based on successful steam network optimization The new district heating network optimization solution is a continuation of Metso's pioneering work on steam network optimization, which has proven to be a success around the world at CHP plants. Core to both solutions are Metso's optimization experts who design, implement and configure the optimization solution based on each customer's requirements, steam network and systems. The solution is built on multivariable model predictive control, which is capable of simultaneously controlling several network variables, predicting primary variables and handling control constraints. At the Suomenoja plant, the optimization package will be integrated into the existing Metso DNA automation system, but it can be integrated into any automation system used at a power plant. "Better control of temperature and pressure fluctuations at the heat plant minimizes heat stress to district heat piping, and thus is one tool to avoid severe disturbances," points out Juha-Pekka Jalkanen, Director, Plant Performance Solutions, Automation, Metso. "Better control of the pressure difference throughout the network also removes the need to produce any additional heat, resulting in higher energy efficiency." Fortum's purpose is to create energy that improves life for present and future generations. The company provides sustainable solutions that fulfill the needs for low emissions, resource efficiency and energy security, and deliver excellent value to its shareholders. The activities cover the generation, distribution and sales of electricity and heat as well as related expert services. Fortum's operations focus on the Nordic countries, Russia, Poland and the Baltics. In the future, the integrating European and fast-growing Asian energy markets provide additional growth opportunities. In 2012, Fortum's sales totaled EUR 6.2 billion and comparable operating profit was EUR 1.7 billion. It employs approximately 10,400 people.
