Met Data Summary for Mayl 2018
(PDF 181 KB)

News:
06/06/18: May Met Summary now available
The figures for May are now in place.  Note the low average wind speed leading to low average wind power during this month.
30/05?18: Windharvester goes to Scotland
Windharvester has gone to its new home in Scotland, and arrived safely in Aberdeenshire the next day.  It was a miracle of packing! Many thanks to all involved.
23/05/18: Britwind H15
To date, the wind turbine has produced 6695 kWh (first three months of service)

The ERU Test Site is located at the STFC Rutherford Appleton Laboratory (RAL). Meteorological data has been logged by the ERU Met Station at the site since 1987 until 2016, while the met station was located at OS coordinates 447175E, 185825N.

The ERU Test Site has recently been relocated a short distance (to OS grid reference SU 47201 85760, coordinates 51.5687N 1.3204W) and new met instruments and a logger have been installed adjacent to the ERU Control Room (Building R111). The met station uses Minimet instruments and a DataHog logger supplied by Skye Instruments, and measures data at 1 minute intervals. The met logger is permanently connected to a PC running a Matlab program which generates graphs updated at one minute intervals, and stores data on an STFC server.

Measurements of wind speed and direction are made using instruments on a met tower (Twr 4) at 18m above ground level; while solar irradiance, atmospheric pressure, relative humidity, temperature and rainfall are measured near to ground level.

Choose an instrument from the list to display a graph of recent data for the last 2 days, updated every 1 minute, or see the graphs for all the instruments on one page.

The historical data have been archived and may be made available for research purposes upon request. Summary charts are available from January 2010 to July 2016

The original purpose for establishing the ERU met station was to aid our research into wind energy and in particular the optimisation of wind turbine design and operation. More recently met data has been provided data to other parts of Harwell Campus for scientific use, including ISIS Health and Safety, Diamond Light Source Ltd, and UKAEA.

Graphs of “real time” data have been displayed on this website since 1999, and are used by staff for various scientific purposes, but also for general interest.

Met Office: "Will it rain today?" for our area

ERU Test Facility at RAL
Windharvester, and all its associated control and lifting equipment was carefully packed onto a lorry.  The nexell is at the front, just behind the cab, and the blades behind it.
The two sections of tower are nested inside each other, with the four leg sections over the top.  All the drive shafts etc are inside the tower sections.  The control box is in front of them, alongside the nacelleThe lifting cables and lifting engine are on the left at the back, and alongside is a big crate containing everything else, including the fantails.... and away it goes to Scotland.
