Ancillary Services
(Applies to Swedish market only)
To sell ancillary services to the electricity grid, you need a Ferroamp system with a battery. You can use the battery for other tasks in the property at the same time as you sell support services, but it is required to make certain settings to distribute the capacity between the different functions.
The service to participate in the ancillary services market with a Ferroamp system is currently offered by Varberg Energi and is called “Flex Batteri”. You must become an electricity retail customer of Varberg Energi to use the service.
About
To sell ancillary services with a Ferroamp system, you need to sign up for Varberg Energi’s “Flex Battery” offer.
The service will be available in all bidding areas once a sufficiently large portfolio of systems has signed up. Initially, this applies to bidding area 3 (except Gotland), but the ambition is to be able to add the other bidding areas shortly.
It is possible to sign up for the service for anyone who has a Ferroamp system with a PSM and ESS battery. In the long term, it will also work with Pylontech H1/M1.
The systems that will be activated first are smaller systems with the following specifications:
– 1 x EnergyHub (Both Wall and XL units work but not several XL units in one rack cabinet)
– Maximum 3 Solar String Optimizers (SSO)
– 1 battery system
In order to be admitted to the bidable portfolio, the system undergoes a system test. Each Ferroamp system is unique and the answers may therefore vary. If you are close to the limit of the system requirements and, for example, have three SSOs, the size and length of cables can play a role. Ferroamp works to minimise these types of restrictions.
The specification for which systems will be released will be developed over time to cover more configurations of Ferroamp systems in a larger geographical area, and it is therefore possible to register your interest right now, regardless of the size of the system you have.
To sell ancillary services, you need to become an electricity trading customer at Varberg Energi and sign up for their “Flex Batteri” service. You can do this here: https://www.varbergenergi.se/privat/tjanster/energilosningar/flex-batteri/battre-ekonomi-med-ett-hembatteri-fran-ferroamp/
When you sign up for the service, you need to provide your Ferroamp ID, which you will find in EnergyCloud on the first page under “System information”.
You must also ensure that import and export restrictions are disabled so that the system can undergo a system test.
If the system is approved, you will receive a notification from Varberg Energi and can then wait for activation of the service.
Once the service is activated, certain settings need to be made in EnergyCloud.
+State of Charge (SoC) needs to be set so that there is always capacity for supporting services.
Set:
Lower limit (SoC%min): 30% or higher
Upper limit (SoC%max): 80% or lower
+ The “Restrict Import” and “Restrict Export” buttons should be disabled (grey).
You can continue to use the Ferroamp system while providing ancillary services. In addition to the short moments when the power grid needs support, your own settings will control the use.
However, some features are limited by the required settings described above:
– Longer battery discharges. With a smaller available SoC range, the amount of energy available for discharge is reduced and the battery cannot discharge for as long.
– Electric car charging. If you control electric car charging via OCPP in EnergyCloud, you will no longer be able to choose to only charge with solar power or to avoid charging at power peaks. On the other hand, the system can still act as a load guard against the main fuse.
– You cannot completely refrain from supplying solar power to the grid, as the export restriction must be turned off.
– External control of the Ferroamp system will not work, but it will still be possible to read data from the system in other systems.
– The “Peak Shaving” setting doesn’t work while selling support services.
Ferroamp works continuously to minimise restrictions so that you can use as many functions as possible at the same time.
