Earth Notes: On Website Technicals (2026-06)
Updated 2026-06-14.: Merit Order Working
The grid-sensitive merit order doing its thing. Today Octopus Agile was offering negative retail import prices; my heat battery and DHW cylinder both topped up to the hilt with a total of >10kWh out of ~29kWh generated, resulting in net exports of ~14kWh, minimal around solar noon.
: Poster Print
I have a poster presentation slot for the Doctoral College conference next week. I have sent off for printing the A0 poster [PDF].
House ads off
Since I do not believe that they have generated any revenue at all, I have disabled the house ads for EOU:
: Journal Paper Submitted
I submitted a journal article Grid Flex Rhymes With Derivatives Trading: an Observation
, based on the Pint of Science
talk concept Pint of Science talk [PDF].
End of POTS
We have received at 16WW Towers notices by email and paper letter that our Plain Old Telephone Service over copper wires will terminate in August, and that we just have to plug a box into the (Virgin) WiFi hub and plug our handset into that and all will be well.
Except we do not get Internet service from Virgin, and we have two handsets plugged into phone sockets in corners of the house about as far as possible from the WiFi as is possible. Virgin does not care of course. So I suspect that we will be moving to cheaper VoIP with a third party ahead of this.
: PNG and SVG
While working on my journal paper I (re)discovered that LaTeX includegraphics is unwilling to use SVG graphics, so I fixed script/storesim/load_profile.sh to generate both SVG and PNG. The former will continue to be the preferred target of my HTML as much smaller, but the PNG will allow other uses such as the paper.
(It turns out that PowerPoint is prepared to use SVG, so I have used an SVG chart in my A0 poster in the hope of maximising sharpness.)
