  • With its sonnenVPP, German battery business Sonnen intends to boost the effectiveness of online nuclear power plant which it states can use key harmonizing power from residences with solar and also storage space and also can run approximately 90% even more cost-effectively.

With an online nuclear power plant (VPP) accumulated from family solar-plus-storage setups running in Germany's key harmonizing power market because November 2018, German power storage space professional Sonnen has actually established software application it claims can run the system as much as 90% even more cost-effectively.

The SonnenVPP plan links property batteries as well as devices to the VPP using a web link for just a fractional added price, according to the firm.

Current modifications to IT demands for Germany's 4 electrical power transmission system drivers imply also little, 25 kW systems-- such as home batteries, heatpump as well as electrical car billing terminals-- can be linked to the Sonnen VPP by means of a VPN net link as well as with no extra tools. The system, claimed Sonnen, implies the power given by the VPP "can be supplied in a completely steady and also substantially extra cost-effective means."


Formerly, it was essential for each residence storage space system attached to the VPP to have its very own communication channel as well as 'media break', which divided it from various other web information. Since demand has actually been gotten rid of, Sonnen can pack systems right into 2 MW systems at information facilities, each with a media break.

In case of considerable web failing, private residence storage space systems can remain to operate as part of the VPP separately, according to Sonnen.

" In the brand-new power globe there is a virtually boundless variety of little systems such as electrical energy storage space, heatpump, electrical cars and trucks or a/c systems," claimed Jean-Baptiste Cornefert, MD of Sonnen E-Services. "Only if they can be conveniently networked can they be made use of smartly in the power system and also take control of the jobs of traditional nuclear power plant."

Broader usage

The adjustment in IT policy implies residence power storage space systems "no more need to act to be a nuclear reactor in a matchbox," included Cornefert.

Sonnen has actually signed up a license for the software program as well as intends to allow third-party suppliers to utilize it under certificate. A joint project has actually currently been established with British utility Centrica.

To day, Sonnen has actually merged 2 MW of solar-linked house storage space for usage in the harmonizing power market in Germany. "We are naturally constantly increasing this as well as are going for a minimum of a tool two-digit-megawatt variety in the tool term," a firm representative informed pv magazine. The brand-new software program as well as clever meter rollout might dramatically increase that advancement.
