http://www.bmreports.com/ contains more data than I can shake a stick at.
I have been wondering for the past little while about electricity prices.
http://www.bmreports.com/bsp/SystemPrices.php?pT=SYSPRICE&dT=NRT
Is interesting - this is as I understand it a graph of the last 48 half-hour periods price for errors in reported generation - how much the grid will pay you, or you will pay as a large generator if you mispredict your generation, and have to buy/sell to make up.
I can't however find a nice similar graph for properly predicted sales from generators.
That is - in the current half-hour period, some generation will have been sold half an hour ago - say for a plant about to start up where the time was uncertain.
They will have gone through the bidding process, and will have eventually gotten to a screen saying 'Click accept to sell 1GWh of electricity for 40000 pounds'.
Generators with more predictable supply may have been able to sell their output for today several months ago, and have gotten a different price.
The graph I'd really like would be of several charts, with average market price, and then the prices paid for past electricity contracts maturing at this time.
So, it would have "average price" over a period, "Average price of half-hour ahead" "Average price of day ahead" ...
Anyone know of such data?
Similarly for buy prices.
I'm wondering from the perspective of small electricity generator unsubsidised viability.
