Previously I’ve provided the figures for Danish offshore windfarms, and for the UK too. Now here are the numbers for the larger German offshore windfarms. The ones shown here are the only ones I’ve been able to get detailed data for, so far.

## German offshore wind capacity factors

All numbers are to the end of March 2017. Analysis by EnergyNumbers.info. | Latest rolling 12-month capacity factor | Lifetime capacity factor | Age (y) | Installed capacity (MW) | Total elec. gen. (GWh) | Power per unit area spanned (W/m ^{2}) | Rolling 12-month capacity factors |
---|---|---|---|---|---|---|---|

Total | 43.2% | 42.5% | 1814 | 9 411 | 3.2 | ||

Amrumbank West | 42.2% | 46.0% | 1.4 | 302 | 1 619 | 4.2 | |

Borkum Riffgrund I | 39.6% | 43.1% | 1.5 | 312 | 1 738 | 3.7 | |

DanTysk | 55.1% | 43.2% | 1.9 | 288 | 2 088 | 1.9 | |

Nordsee Ost 1 | 37.0% | 37.0% | 1.9 | 144 | 875 | 3.0 | |

Nordsee Ost 2 | 37.1% | 37.1% | 1.9 | 144 | 885 | 3.0 | |

Sandbank | 56.9% | 0.2 | 288 | 252 | |||

Windpark Baltic 1 & 2 | 43.6% | 46.8% | 1.4 | 336 | 1 956 | 4.3 |

## Load duration curves

I’ve constructed for each of the offshore windfarms for which there is detailed hourly data. Use the pause and play buttons to stop and start the sequential display of curves. Click on the windfarm name in the legend to toggle the display of that farm’s curve.

## Methodology

Note that for each individual windfarm, its curve is based on data starting from the date that the windfarm was fully commissioned.

The numbers for DanTysk do look strange: I’m investigating how to deal with the problematic sections of data.

Windfarms less than a year old are excluded from the calculations of the power density per unit area spanned. The figure for total power density is a weighted average of the windfarms that are a year older or more: this is weighted by size, but not by time. So a windfarm that’s twice as large contributes twice as much to the total; whereas a windfarm that’s twice as old, does not.
