is not exactly compliant with the 'keep calculations to minimum' policy, but it might be possible to show a generation mix for Swedish bidding zones.\r\n\r\n- Statnett/Svenska kraftnät have real-time flow data\r\n- Statnett/Svenska kraftnät have a rough fuel mix for all of Sweden\r\n- ENTSO-E has wind generation for Swedish bidding zones\r\n- ENTSO-E/Svenska kraftnät have consumption for the bidding zones\r\n\r\nMoreover, based on statistics by Svenska kraftnät at https://www.svk.se/aktorsportalen/elmarknad/statistik/ we can deduce:\r\n- All nuclear capacity is located in the bidding zone SE3\r\n- Over 98% of annual non-wind power generation in SE1 comes from hydro\r\n- Over 97% of annual non-wind power generation in SE2 comes from hydro\r\n- SE3 has annually 5 to 9 times more hydro generation than SE4 (on average 2010-2016 7.4 times)\r\n\r\nThen to calculating hydro and thermal generation for each zone:\r\n- Consumption and flow data allow calculation of total generation for each bidding zone\r\n- We can subtract wind generation(ENTSO-E, all areas) and nuclear generation(statnett/SE3) from the total generation figures to get (hydro+unknown) generation for all areas\r\n- By assuming that hydro makes up let's say 98% and 97% of (hydro+unknown) generation in SE1, and SE2, respectively, we have the fuel mix down for SE1 and SE2\r\n- Subtracting SE1 and SE2 generation from the Statnett generation figures for all of Sweden, we have an estimate for the fuel mix of (SE3+SE4) and the total generation for both SE3 and SE4\r\n\r\nThe remaining problem is to solve the hydro-to-unknown ratios for SE3 and SE4:\r\n- We could fix that something like 12% of hydro generation in (SE3+SE4) occurs in SE4, or use some MW lower/upper bounds for hydro/thermal to get the fuel mix for SE3 and SE4\r\n- Alternatively, we could lump SE3 and SE4 together\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/tmrowco/electricitymap/issues/comments/388300972","html_url":"https://github.com/tmrowco/electricitymap/issues/1397#issuecomment-388300972","issue_url":"https://api.github.com/repos/tmrowco/electricitymap/issues/1397","id":388300972,"user":{"login":"maxbellec","id":7253902,"avatar_url":"https://avatars2.githubusercontent.com/u/7253902?v=4","gravatar_id":"","url":"https://api.github.com/users/maxbellec","html_url":"https://github.com/maxbellec","followers_url":"https://api.github.com/users/maxbellec/followers","following_url":"https://api.github.com/users/maxbellec/following{/other_user}","gists_url":"https://api.github.com/users/maxbellec/gists{/gist_id}","starred_url":"https://api.github.com/users/maxbellec/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/maxbellec/subscriptions","organizations_url":"https://api.github.com/users/maxbellec/orgs","repos_url":"https://api.github.com/users/maxbellec/repos","events_url":"https://api.github.com/users/maxbellec/events{/privacy}","received_events_url":"https://api.github.com/users/maxbellec/received_events","type":"User","site_admin":false},"created_at":"2018-05-11T08:41:42Z","updated_at":"2018-05-11T08:41:42Z","author_association":"CONTRIBUTOR","body":"actually, it seems very unlikely that Nya Öresundsverket in SE-SE4 has a low generation, as it's relatively new (2009).\r\nAnd Wikipedia says there's another large power plant in SE-SE4, Karlshamn, that has a capacity of 665 MW and burns oil, but this one's quite old.\r\nhttps://de.wikipedia.org/wiki/Liste_von_Kraftwerken_in_Schweden\r\n\r\nAnother source is the ENTSOE generation per unit. Most of SE-SE3 is reported (but not everything), and none of SE-SE4 is reported (and Karlshamm is missing).\r\n\r\n![screenshot at 2018-05-11 10-14-26](https://user-images.githubusercontent.com/7253902/39914097-432a0cc0-5504-11e8-99f0-b1ee4a31ad44.png)\r\n![screenshot at 2018-05-11 10-14-08](https://user-images.githubusercontent.com/7253902/39914099-444ce172-5504-11e8-8118-cc82c6ab4cf4.png)"}}
