The Hastedt steam power plant was built in 1905 in the Hastedt district of Bremen . It is located on the right bank of the Weser a little above the Weser weir and is the oldest power plant in Bremen .
history
For the time it was a modern three-phase power plant with turbine drive and an output of 2,400 kilowatts (kW). For a long time its chimneys - "the seven black ravens" - shaped the appearance.
With the natural gas-powered power plant unit 14 with an output of 155 MW, the first fully automatic power plant in Bremen was put into operation on the company premises in 1972. Block 14 primarily served to cover the electricity demand during peak load times . At the beginning of 2014 it was transferred to the cold reserve and completely decommissioned in 2016.
In 1989/90 a new coal block was built with Block 15 . This uses the process of combined heat and power to generate electricity and district heating in parallel . Up to 1,000 tons of hard coal are burned every day . Block 15 was designed according to plans by the architects Schomers, Schürmann and Stridde.
Together, the two blocks have an electrical output of 268 megawatts and a thermal output of 283 megawatts . The emission of pollutants is significantly reduced by modern environmental technology.
The power plant is operated by swb Generation AG & Co. KG .
Fire from 2008
On October 12, 2008 at 10:45 am, the shift management noticed a fire in coal silo 4. A smoldering fire developed in the 3,000 tons of hard coal in the 30 meter high silo . Fire brigade and employees initiated the emptying.
There was a deflagration on October 13, 2008 . Smoldering gases had accumulated above the coal layer and formed an explosive atmosphere . The roof and the conveyor system were destroyed by the pressure wave . This resulted in the measure of removing the silo in order to get to the embers. From October 17th, a special excavator was used for the demolition . 10 days after the fire broke out, on October 22nd, the fire was extinguished and the silo tower emptied. In 2009, swb put the property damage at around 4.2 million euros.
Fire from 2009
On the afternoon of July 9, 2009, employees noticed increased temperatures and smoke development in day bunker 3, in which around 270 tons of coal were stored at that time. Fire and rescue services were on site with 65 men. Overnight, the coal was largely burned in normal operation and the embers disappeared. After Block 15 was disconnected from the grid the next morning and its electricity and heat production stopped, the manual clearing of the remaining amounts of coal began.
The cause for the creation of the glowing nests is “the coincidental coincidence of various technical circumstances”. Accordingly, the plant was idle due to a malfunction. The fire alarms were triggered just a few minutes after restarting. The charcoal had accidentally dried out and self-ignited. Swb has invested around one million euros in repairing the damage and in additional security technology.
Hybrid control power plant (HyRek)
The hybrid control power plant (HyRek) with an output of 15 megawatts (MW) went into operation in April 2019. The HyRek is used to flexibly compensate for fluctuations in the generation of electricity by photovoltaic and wind power plants . To keep the grid stable, flexible balancing energy is required, which can be fed into the grid when required. For this purpose, the power plant unit 15, which is already connected to a heat storage system, was supplemented with an additional powerful lithium-ion battery storage system . This means that excess electricity can be temporarily stored for future control energy feed-in. The battery is used almost exclusively to transfer energy into the grid and therefore has a higher usable capacity. In the case of energy consumption from the grid, the electrical energy in the hybrid power plant is fed directly to an electric boiler with an innovative switch. In this way, electrical energy can in turn be saved as heat in the heat storage system - and fed into the district heating network in the east of Bremen if required.
