I want to get a visual feeling for the distribution of electricity and heating load over the year. There are national load curves, then there are reference load curves for individual (mainly residential) buildings. But I would like to get something in between. Proxies like output of district heating or cogeneration plants are fine, too.
I'm not picky: The preferred time resolution is 1 hour, covering a full year, in moderate (i.e. summer-winter-cycle) climate. But I take daily, even weekly resolution anywhere on the globe.
The only hard requirement: open data with clear license, not a pixelated graph in a report that may not be reused.
