It may be partially an effect of the end of term, but the PV seems to be taking chunks out of the Hugh Aston peak electricity (see graphs). @DMU_Energy suggested we could get hold of the data - might be a nice project to understand the likely difference PV has made (using smartspaces model median as what would have been vs. what actually was). Maybe an MSc idea...

Still trying to get the data logger to work. We need to install a different system from the one we normally use, do to the voltages involved but as soon as it is installed and working I will be more than happy to share the data.

Excellent - is it anything we (IESD) could help with, or is it just a case of waiting for a company to come and install? In a previous life, I did some logging of unusual voltage circuits (100V, 125 Hz...)

Thanks for the offer. The issue is getting the logger to work in parallel with the Display Units in the public spaces. The AMR loggers are zero volt units, but the displays send 4.3V back up to the meter, which the loggers can't handle. We've tried chatterboxes, but this still doesn't seem to work. We are looking to use a different logger (23V) that can handle the display rtn voltage, This requires fused spurs and transformers to be placed in the meter areas (which causes delays, costs, etc). Hopefully this will get sorted in the next month.
