25-Year-Old Danish Offshore Wind Farm Gets Approval To Operate For 25 More Years

The title of this post, is the same as that of this article on offshoreWIND.biz.

This is the sub-heading.

After approving the production permit extension for the Samsø offshore wind farm earlier this month, the Danish Energy Agency (DEA) has now granted extended permits to two more of Denmark’s oldest offshore wind farms, Middelgrunden and Nysted.

These first two paragraphs add more details.

To support its decisions, the DEA has requested that the applicants for the production permit extensions deliver an impartial analysis of the remaining lifetime. After receiving the extensions, the owners are now obliged to carry out comprehensive annual service inspections.

The Middelgrunden offshore wind farm was built in 2000 and received its electricity production permit the same year, before full commissioning in March 2001. The DEA has now approved Middelgrunden to operate for 25 more years.

This must be a very good thing, if with a good well-planned maintenance regime, engineers can get a productive life of fifty years out of an offshore wind farm.

With nuclear power stations, engineers seem to be able to predict their life expectancy fairly well, so if we can do the same with wind farms, it must make the planning of future power capacity a lot easier.

I asked Google for an answer to how long do nuclear power stations last and got this AI Overview.

Nuclear power plants are typically designed to operate for 40 to 60 years, but some can be extended to 80 years or even longer with upgrades and maintenance. Early plants were often designed for 30 years, but many have been refurbished to extend their operational life, according to the World Nuclear Association. The actual lifespan can also depend on factors like financial viability, operating costs, and the need for decommissioning, according to the National Grid Group.

As I suspect that solar farms could remain productive for fifty or sixty years, a mix of nuclear, solar and wind should serve us well in the future. Especially, as every next generation of nuclear, solar and wind power should be better than the last.

As a very experienced mathematical modeller, I like it.
