That with natural gas -fired cogeneration plant Niehl the RheinEnergie in Cologne district Niehl supplied among others, the Cologne city center with district heating .
History, structure and dates
Old plant (power plant I)
The original plant, commissioned in 1977, was based on a gas and oil-fired Benson tower boiler. From this, an electrical output of approx. 315 MW plus approx. 350 MW district heating was generated on the steam turbine .
The height of the building is 180 meters to the top of the chimney on the roof.
Water is taken from the Rhine port for cooling; the existing wet cooling tower at the site is only used if the permitted warming of the Rhine is exceeded in warm summer months or when the water level is low.
Plant I was shut down after the construction of Plant II (see below) and was dismantled by 2008.
At times, RheinEnergie examined the construction of a hard coal power plant at the Niehl site as a replacement for power plant I. However, these plans were rejected or at least postponed in 2007 - mainly because of the increased construction costs.
Combined cycle power plant (power plant II)
From 2003 a modern combined cycle power plant was built at the site . It is based on a gas turbine from Siemens Power Generation , type V94.3A (today SGT5-4000F ) with an electrical output of approx. 266 MW. Downstream is a waste heat steam generator from Balcke-Dürr Austria with three pressure stages and reheating . The steam volume of around 350 t / h produced is fed by a steam turbine with an electrical output of around 145 MW plus 370 MW district heating.
The cooling water system and the district heating system were largely taken over from Plant I.
Combined cycle power plant (Niehl 3)
In September 2012, the decision was taken, the location Niehl with another combined cycle - cogeneration plant to expand. The general contractor is Alstom , which supplies a GT26 gas turbine, a steam turbine and the turbo generator, as well as other power plant components. Construction began in December 2013, and test operations began at the end of September 2015. In September 2016, it was officially inaugurated.
The power plant is connected to both Amprion's 380 kV network and the 110 kV network of Rheinische NETZ-Gesellschaft, a 100% subsidiary of RheinEnergie AG founded in 2006 . It is designed for an electrical output of 450 MW and can extract 265 MW of district heating. The electrical efficiency is 60% and the fuel efficiency is up to 88% with district heating. The investment volume is around 350 million euros. In addition, it can be regulated quickly and can be ramped up from standby to nominal power in less than 15 minutes. In addition, it can be operated flexibly in the power range from 20 to 100% of its nominal power.
