JSC Coal Company Krasnoarmeiskaya Zapadnaya has signed a framework agreement with GE Energy that will see up to 20 Jenbacher coal mine gas-fuelled cogeneration units installed at the mine.
The engines will use the active mine’s own methane gas to generate about 129 MW in total power output, covering the mine’s on-site power and heat requirements.
The cogeneration units will operate in parallel to the local grid. The plant will have total outputs of 60.9 MWe and 67.8 MWth, with the electrical and thermal power being used to support mine operations.
The Jenbacher units are scheduled to be delivered to the site between 2008 and 2011. GE is also supplying a complete heat utilization system, emergency cooling, control and synchronization system, as well as start-up and commissioning.
The privately owned mine is located near the town of Krasnoarmeisk in the coal-rich Donetsk region in eastern Ukraine. While many coal mines in Central and Eastern Europe have traditionally utilized a small portion of their coal mine methane (CMM) for generating steam, Ukraine has become a regional leader in installing the latest technology to expand the use of the gas for on-site power generation.
When the Krasnoarmeiskaya Zapadnaya project reaches full operation, it is expected to potentially reduce the equivalent of more than two million tonnes of CO2 emissions per year, compared to venting the gas into the atmosphere – qualifying the plant for carbon emission trading certificates.
‘Ukraine is encouraging its coal mines to modernize their operations, including the use of mine gas as a new source for on-site power to improve energy efficiency and support the nation’s economic and energy security objectives,’ said Alex Pavlov, GE’s Jenbacher gas engine Sales Manager for the Ukraine.
The power project’s engineering and procurement contractor (EPC) Sinapse CHNPP of Kiev secured the framework agreement to install up to 20 of GE’s 3-MW, JMS 620 GS-S.L. systems, which are designed specifically for projects with low methane contents. Sinapse is also GE’s authorized Jenbacher engine distributor for the region. Long-term service for the Jenbacher units will also be provided by Sinapse.
