Public entities will not be acquiring these batteries.
This “improving reliability and stability” that is talked about in these cases is grid frequency support. That is exactly what I was talking about. That is, support for Fingrid’s frequency market.
This is an operation done purely with cash flow and market activity in mind.
It is paid for, and that’s why it’s done.
It does not enable “island mode operation” which you talk about as being able to prevent local power outages.
For that, the operation would have to be different and in different markets. Merus does not participate in these markets.
“An electricity storage facility located in Ostrobothnia does not help Lappeenranta if the transmission connections to Lappeenranta are cut off.”
→ Not this either, because this does not participate in such markets.
The same thing with Elisa’s battery. Of course, Elisa’s battery protects the consumer.
The techno-economic reasons for purchasing these battery systems are very different from what you imagine.
In addition, batteries are currently placed especially in connection with, for example, wind power.
Of course, they are also beneficial in consumption.
Elisa’s battery and Optimization are also familiar.
But even that does not create the functionality for the grid that you think it creates.
