How DSO estimate annual PV production 1

Hi, my question is how Distribution System Operators(DSO) of a country/region estimate how much PV production is obtained from Households? I am not sure if they collect this data from smart meters, or if they somehow estimated it. For instance if the installed PV capacity is known, is it possible to estimated it making some assumptions? which would be those assumptions.

Thank you in advance for any light on the matter.

This varies widely by region and by method of subsidy. There are lots of estimating tools for both real time production and annual production.

My region (USA-Washington state) subsidizes solar via production credits, so households here almost always have a separate PV production meter. Each distribution utility in my region should also have a record of the total wattage installed on each house. Solar production is still pretty small in my region, so we have not yet invested detailed production estimates. One big challenge is trasferring detailed data on PV installations from the DSO up to the Transmission Operator and Balancing Authority.
 
What does contain the details data you give to TSO basically? As I understand, some countries have set themselves targets of PV annual production (some relay basically on household production) for future years, so if they what to increase their production by XXX by the year YYY, then they have to have an idea how much is their production at the moment So, I was wondering how do they do it.

More nice input are welcome
