Best European Countries for Power Hungry Data Centers

Image
The chart tells us that Ireland despite its low tax rates is quite costly with the highest power rates in the EU. It is often joked that a data centre is a power reseller and there's a lot of truth in that statement. For example, Equinix reports that power and cooling are 80% of its infrastructure operating expense. In general, a data centre's overall operating expense can be as much as 50% electricity. From what I can tell Irish data centre demand for electricity has grown much faster than the country's power capacity. Data centres consume 21% of Ireland's electricity versus 18% for households. This is an astonishing figure.  High German rates reflect the failed Energiewende. The system costs of wind and solar are extremely high in Germany and both sources are heavily subsidized via guaranteed tariffs because the load factors (annual capacity utilization rates) are very low. For example, a German solar farm only operates at 10% of capacity on an annual basis whereas Am...

IOEMA: The New 48 Fibre Pair Repeatered Subsea Nordic Cable

Image
Type of Cable System: Repeated Two-Core Fibre Pairs With Coherent Optics  Consortium Members: Independent Operator. Construction Status: Design and Fund Raising Stage.  Number of Fibre Pairs: 48.  Number of Cores Per Fibre: 2. Estimated RFS: 1st or 2nd quarter 2027. Day One Aggregate Throughput: 13 Pbps.  Salient Features: 48 Pair repeatered cable directly linking UK, Norway, Demark, Germany, and Netherlands. Every fibre optic path is direct and involves no third country transit. Each fibre pair strand has two optical cores instead of the standard one.  Supplier: NEC. Only NEC offers multicore fibre strands and 48 pair repeaters.  I interviewed today one of the project's founders, Eckhard Bruckshen. The IOEMA cable is designed to reduce the dependence of European telecommunications traffic on the Denmark bottleneck as the map below illustrates. Today Denmark is the primary telecom bridge between the Nordic countries of Norway, Sweden, and Finland (also the ...
