HEW plant Tiefstack (1986)

The Tiefstack combined heat and power plant (often just referred to as the Tiefstack power plant ) is a coal-fired power plant and combined cycle power plant (CCGT) in the Hamburg lowland area of Tiefstack . The power plant generates electricity that is fed into the Hamburg electricity network and heat that is fed into the Hamburg district heating network.

The power plant is located in the Hamburg-Billbrook district in the border area to the Hamburg-Rothenburgsort district , which both belong to the Hamburg-Mitte district .

history

The former coal-fired power station of the Hamburgische Electricitäts-Werke (HEW) was put into operation on January 17, 1917 with a nominal output of 20,000 kW. The coal-fired power plant with its four distinctive chimneys formed the HEW logo for several decades from 1923. Construction of the power plant began in 1914. When it was completed in 1925, it had 24 boilers and a nominal output of 85 MW, which, after the turbines were replaced, increased to 130 MW by 1953. In 1933, the plant was equipped as a combined heat and power plant that supplied steam to the Hamburg district heating network according to the principle of combined heat and power . In 1950 the plant was modernized into a high pressure power plant. The originally 100 meter high chimneys of the power plant were shortened in 1952 to a height of 75 meters.

From 1984 on, a combined heat and power plant with hard coal firing was built on an area flushed with sand from the North Elbe next to the power plant , which started operation in 1993. In the same year the old power station was shut down and demolished until the mid-1990s. The new power station has been in operation since Vattenfall Europe Wärme took over HEW . On the site of the coal-fired power plant, a gas and steam combined cycle power plant with 125 MW was also put into operation in 2009 , which burns natural gas .

The Tiefstack gasometer , built in the 1930s, was demolished in 1986.

Change of ownership: from Vattenfall to the city of Hamburg

In a referendum in 2013 it was decided that the city of Hamburg should take over the district heating network from Vattenfall in full. This is a so-called remunicipalisation , see also people's legislation in Hamburg #remunicipalisation-energy . The district heating network also includes the Wedel and Tiefstack thermal power stations .

On November 29, 2018, the city of Hamburg announced to the energy company Vattenfall that it was taking advantage of the option to buy back the district heating network. Among other things, Vattenfall's Tiefstack power plant is to be transferred to the city.

The change of ownership should take place in 2019. After the change of ownership, Vattenfall is no longer the operator of the Tiefstack power plant, but the city of Hamburg. This makes the city the sole point of contact for particle emissions and claims settlement .

In September 2019, the city of Hamburg announced that by signing the purchase agreement and paying the purchase price of EUR 625 million to Vattenfall with retroactive effect from January 1, 2019, the takeover of the heating company had been completed. In addition to the district heating network itself, the heating company also has several generation plants, including the Tiefstack power plant.

Change of fuel: from hard coal to natural gas

In August 2019 Red-Green published Senate Tschentscher I an affirmation that after a summit meeting of mayors and senators CO 2 - emissions reduction of Hamburg by 2030 by 55 percent to want. Suitable measures are to be identified within the framework of an “Alliance for Climate Protection”, with priority being given to measures with a high leverage effect . These include major projects such as the conversion of the Tiefstack power plant from coal to gas and the priority feed-in of renewable energies.

The Tiefstack thermal power station is to be converted from hard coal to natural gas by 2025 , so that electricity and heat can be generated entirely without coal.

Other sources report that the Tiefstack power plant is not expected to become carbon-free until 2030. The Wedel power plant, which is operated with hard coal , is to be taken off the grid with the heating period of 2024/25.

As part of a feasibility study , it was analyzed in 2019 which measures had to be carried out so that the fuel from the two coal-fired steam generators of the Tiefstack cogeneration plant can be switched to natural gas.

In 2017, Vattenfall had already considered whether it would make sense to convert the Tiefstack power plant from coal to gas early.

Shutdown in 2030

The Tiefstack power plant is to be shut down by 2030.

It has not yet been clarified how the city of Hamburg will replace the Tiefstack thermal power station. An alternative would be to use the industrial waste heat from companies in the Port of Hamburg , including the copper producer Aurubis , the aluminum producer Trimet Aluminum and the steel group ArcelorMittal . The thermal recycling of waste is also seen as an option.

Other sources report that the Tiefstack power plant is to be replaced by an “Energiepark Hafen” with a gas power plant , which is to be located south of the Elbe. In addition to the Tiefstack power plant, which will be shut down by 2030 at the latest, this Hafen Energiepark is also intended to replace the 60-year-old Wedel power plant , which will be shut down in 2025.

Others

From 2006 to 2009 the Tiefstack power plant was expanded to include a combined cycle power plant . The plant was put into operation in 2009.

In December 2008 a smoldering fire broke out in a coal silo at the Tiefstack power plant . However, the fire was classified as harmless.

In July 2010, the Tiefstack power plant could only be operated with reduced output because the water temperature of the Elbe was too high. If the water temperature of the Elbe rises above 20 ° C, the power plants on the Elbe, to which the Tiefstack power plant belongs, are only allowed to use smaller amounts of the Elbe water as cooling water so that the river is not heated any further. Such situations occur regularly during the summer.

In 2013, the Tiefstack power plant, which at that time still belonged to Vattenfall, was the largest industrial greenhouse gas emitter in the city of Hamburg (data as of 2010). The carbon dioxide emissions of the Tiefstack power plant are almost 1.5 million tons of CO 2 per year. This means it has a share of around 29 percent of the total emissions of the eleven registered companies that state their CO 2 emissions.

In 2018, around 490,000 residential units were connected to the district heating network in the city of Hamburg. By 2020, 500,000 residential units are to be connected to the district heating network.
