Wedel Power Station

The CHP plant frond is a coal- fired power plant of Vattenfall in Wedel, Schleswig -Holstein, on the Elbe and the border to Hamburg located. Characteristic of the plant are the two each 151 meters tall chimneys. The elbseitige chimney is shut down for several years.

History

The power plant is a thermal power station Wedel and was built in the years 1961-1965 by the then Hamburg Electricitäts -Werke AG ( HEW ). At the same time located at the same site power plant Schulau was decommissioned. The building design was by the architect Bernhard Hermkes Becker and Gerhart. Initially there was the technical installation of four blocks with a total capacity of 600 megawatts.

By 1987, the power plant was exclusively in the power of Hamburg. In order to use the power plant for the heat production, 1988/89 two blocks for combined heat and power were rebuilt. At the same time a flue gas desulphurization and denitrification plant was built. From 1990 to 1993, the plant was placed in a major overhaul on the cutting edge of technology, thereby extending the operating life of 25 to 30 years.

Specifications

According to Vattenfall details the CHP in Wedel has the following data:

  • Electrical power: 250 MWe
  • Heating capacity: 423 MWth
  • Average annual electricity generation: 1200 GWh
  • Average annual heat production: 1200 GWh
  • Main Fuel: Hard coal
  • Condensing power / power cogeneration: combined heat and power ( CHP)

The power plant consists of two blocks, which can be operated separately to adjust production to the changing electricity and heat demand. It also has two gas turbines for peak load production.

The total power generation of Vattenfall is 163,900 GWh. The share of coal-fired power thereto is 95 002 GWh. Wedel provides approximately 240,000 households with electricity. At the landing of the coal power plant has a suitable also for ships with stronger draft its own port.

Planned gas - and -steam combined cycle power plant

Relation to coal-fired power plant Moor Castle

The district deployment of the power plant fronds should be taken over by the new coal power plant Moor Castle with loud Vattenfall, which is expected to become operational in 2014. The dimensions of the two power plants are significantly different: the future KoKW Moor Castle is considerably larger in size and will provide electrical and up to 650 MW of thermal power ( district heating) up to 1600 MW. Therefore, the power plant Moor Castle should bring additional thermal performance through new-build district heating pipeline ( the so-called Moor Castle route ) under the same round up to Altona. The necessary approval procedures was declared by the Supreme Administrative Court of Hamburg to a suit of the BUND Hamburg and a citizen invalid. The simplified plan approval process needs to be replaced by a plan approval process with public participation and environmental impact assessment. In connection with the acquisition of 25.1 % of Hamburg's energy networks by the City of Hamburg Vattenfall renounced the construction of Moor Castle route.

Vattenfall is now, together with the city of Hamburg as an alternative to a gas -powered gas - and -steam combined cycle power plant to provide the necessary district heating. This requires both a site in Hamburg -Stellingen and the Wedel in Schleswig -Holstein were examined. For the location decision, a common cost comparison was performed by the City of Hamburg and Vattenfall. A presentation of the cost-effectiveness calculation to the citizenry of the City of Hamburg and a general posting are not provided, but a given from the city of Hamburg commissioned report concludes that the site fronds against the Hamburg -Stellingen cost savings of at least 100 million euros leads due to existing connections and lines.

CO2 emissions

A report, which was commissioned by the city of Hamburg in late 2011 in order, comes in this context the following results:

  • The planned gas - and -steam combined cycle power plant is under CO2 perspective, the best possible alternative for generating the Hamburg district heating.
  • Compared with the existing energy production of Altkraftwerks Wedel, a reduction of total CO2 emissions by around 50%.
  • The planned thermal storage leads to improved integration of electricity from renewable energy sources in the overall system.
  • The proposed combined cycle power plant is in terms of CO2 emissions a solution with many small CHP plants that feed into the grid, preferable.

Planning and approval

Overall Design for the construction of the company Pöyry. By the beginning of October 2012, there was the opportunity to submit an appeal for concerned citizens. More than 1,000 citizens and numerous environmental initiatives have objections to the planned power plant collected, which is to take over the district heating supply in the west of Hamburg. At the same time with this power plant is a hot water tank to be built, in which excess current is converted from renewable energy sources in hot water by immersion heater principle. Such a hot water storage also employ Stadtwerke Flensburg.

The decommissioned according to the original plan in 2013 Wedel power plant in October 2011, a maturity extension to the heating season 2016/17Vorlage: / In 2 years receive future to ensure the district heating Hamburg to the commissioning of the new cogeneration plant can .. From then apply throughout Europe new emission standards, which would have a significant investment in the upgrading of the old power station result ..
