Metso is to facilitate the Martinlaakso 1 power plant in Finland with an online solution that will enable Vantaan Energia to accurately monitor its carbon dioxide (CO2) output.

The power plant is the first in Finland to receive approval for this measurement-based method from the Finnish Energy Authority, the national administrator for the EU Emissions Trading Registry.
“The new online solution replaces traditional CO2 reporting based on fuel data. 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,” says Tiina Stenvik, Solution Manager, Process Automation Systems, Metso.

The CO2 monitoring system was commissioned at the coal-fired Martinlaakso power plant in 2013. In addition to Metso, the system suppliers include SICK, who delivered the online measuring equipment, and Indmeas, who supplied the flow measurements.

“Metso’s monitoring and reporting application provides us with real-time information about the plant’s CO2 emissions. Before installing the system, this emission information was obtained by sampling and weighing the incoming fuel,” says Samuli Björkbacka, Operations Engineer, Vantaan Energia. “The information provided by the new application is used in our process calculations and in verifying the plant’s CO2 emissions for the authorities. Online monitoring also allows the operators to immediately see possible measurement malfunctions.”

“One glance at the trends shows where we are standing with the CO2 emissions.” The application provides reports on a daily, monthly or yearly basis.

The Martinlaakso power plant produces about two-thirds of Vantaa Energy’s electricity output and most of its district heat. The total electrical capacity of the plant is about 195 MW and thermal capacity is 330 MW
