How it is calculated
Home savings = what all the electricity consumed would have cost if bought from the grid at the home connection's full price, minus what was actually paid to the grid, plus revenue from electricity sold through the home connection.
Solar park revenue is the revenue from electricity sold at spot price through a separate connection. It is business revenue, not home savings.
Sales and purchases come from Elering meter data, consumption from the home's energy meters. A finished month is added on the 8th of the following month; the current month updates once a week.
On 36 days the consumption or meter data has gaps. Those days include only the measured part.
This page updates itself: Home Assistant, the Elering API and a database, no manual work. Let's talk about what your data could do.
