I plan to develop a scenario in SAInt where a battery storage system serves two distinct roles within a 24-hour cycle, depending on the time of day: From 12:00 to 16:00, the battery should function as a spinning reserv… --- ## [How to create an event to degrade ESTR efficiency?](https://forum.encoord.com/t/how-to-create-an-event-to-degrade-estr-efficiency/354)

I’d like to model extreme temperatures degrading the round-trip efficiency of my electric storage devices for a “heat-wave” month.

I think it’s pretty clear that we define the energy capacity of a battery in the “MaxCapDef”. Is this correct? For the power capacity though, should we define this value in both the “PDMAXDEF” and the “PGMAXDEF”?

I am modeling a battery design which the manufacturer states has a 90% round trip efficiency. In order to correctly model this in SAInt, should I set PGeff and PDeff both to 0.95? --- ## [Plot Battery Charging Below X-axis?](https://forum.encoord.com/t/plot-battery-charging-below-x-axis/346)

How do I plot battery charging below the x-axis (ie negative) like the default generation dispatch plot does? Currently my code stacks it onto the positive side. I’ve tried putting a negative sign in front of POUT, but … --- ## [Battery charging and discharging](https://forum.encoord.com/t/battery-charging-and-discharging/274)

I would like renewable sources charge batteries when prices are low (ie. RE is plentiful) and then discharge the batteries when the network needs it during higher priced times (or when RE is not available).

Hello, I am working with storage assets in ENET. I found parameters to define the Minimum down time or Minimum Zero Time (MZT), but not for minimum up time. Is it possible to define Minimum Non-Zero Time for both charg…
