Vantaan Energia’s Martinlaakso 1 power plant is the first to receive approval for online CO2 reporting from the Finnish Energy Authority, the national administrator for the EU Emissions Trading Registry. The online system is based on Metso’s reporting application, as well as online measurement equipment from SICK and flow measurement systems from Indmeas. The system was commissioned at the coal-fired plant last year.

"The new online solution replaces traditional CO2 reporting based on fuel data,” said Tiina Stenvik, solution manager – process automation systems at Metso. “It fulfills the complex reporting requirements of the EU Emissions Trading System by providing all necessary information for the verification process and authority reporting. It also monitors the availability of the CO2 measurement system and generates alerts to notify plant operators about deviations."

The monitoring and reporting application is fully integrated with the plant automation system and provides real-time information about the plant’s CO2 emissions, explained Samuli Björkbacka, operations engineer at Vantaan Energia. Previously the plant has to rely on information obtains by sampling and weighing the incoming fuel.

"The information provided by the new application is used in our process calculations and in verifying the plant's CO2 emissions for the authorities,” continued Björkbacka. “Online monitoring also allows the operators to immediately see possible measurement malfunctions."

The new monitoring and reporting application is based on the Metso DNA information system, which is integrated with the Metso DNA automation system, and has been developed from the company’s experience in developing online emissions monitoring applications that are widely used at large combustion plants and waste-to-energy plants around the world.
