Svenska hushåll kan sänka elnätsbelastningen betydligt genom flexibel elförbrukning — men framför allt om styrsystemen förstår både väder och personliga önskemål samtidigt. Forskargruppen vid Umeå universitet utvecklade en hemenergihanteringssystem (HEMS) som hanterar osäkerhet i solcellsproduktion medan den balanserar fyra konkurrerande mål: lägre kostnad, mindre CO₂, större energioberoende och mindre topplastvariationer. I ett pilotprojekt med ett svenskt enfamiljshus reducerade systemet elkostnaderna med 9,5 procent, koldioxidutsläppen med 9,3 procent och topplasten med 52 procent jämfört med regelbaserade alternativ — allt utan att offra boendekomfort. Den stokastiska planeringen minskade felmarginalen med 33,3 procent gentemot deterministiska metoder. För leverantörer av energistyrning och nätoperatörer är resultatet relevant: occupant-centrisk optimering under svenska tariffer möjliggör skalbar flexibilitet på stadsnivå utan att tvinga bort användare genom rigid automation.
