The 250 MWe/423 MWth hard coal-fired plant (pictured) provides district heating to the city of Hamburg. Vattenfall said the upgrades are necessary to secure the city’s heat supply for the next few years and to comply with current environmental standards.
Work is scheduled to begin in the summer and will focus on the plant’s turbines, boiler and control system. According to the firm, most of the work is planned for the summer months this year and in 2017-18.
Looking ahead, Vattenfall said it will collaborate with the City of Hamburg on finding a longer-term solution that will result in a secure heat supply. It plans to eventually replace the coal-fired plant, which was built in 1961 and converted from power-only to CHP in 1987. It was last upgraded to comply with environmental standards in 1993.
On its website, the company said the existing district heating pipes and connection will remain in use.
Tuomo Hatakka, Vattenfall’s Head of Business Area Heat, said: ‘In parallel to the refurbishment of the plant in Wedel Vattenfall is developing a concept to achieve climate neutrality in Hamburg heat operations by 2050. It could include heat storage, power-to-heat, industrial heat, decentral solutions and possibly gas-CHP that will replace the existing plant. The concept will be developed in close alignment with the City of Hamburg.’ à‚
