Tesla has partnered with ReStore, the Belgium demand response start-up bought for €70million ($81million) in November 2017 by UK-based Centrica, to build a 18.2MW lithium ion virtual power plant for grid balancing services in Belgium, Tesla announced on May 14.
The system at Terhills, in northeast Belgium, is using 140 powerpacks to store excess renewable power for use at times of peak demand.
The system has been integrated into the primary reserve of Elia, the national grid administrator in Belgium.
This February, South Australia’s government announced a trial of VPPs and installation of a 4.3MWh lithium ion micro-grid using Tesla’s batteries.
The A$10.5 million ($8 million) system is paired with a 2.5MW array using 1,600 solar panels at a facility in Pooraka to deliver wholesale market energy needs and feed surplus power into the broader grid for peak shaving services.
The microgrid is set to be fully operational by late 2018 and should remain operational for up to 20 years. Results of the initial trials will finish in June 2019, and the programme could be extended to at least 24,000 housing trust properties and 25,000 private properties across South Australia.
Tesla is due to establish a service hub at Tonsley, near Adelaide — a commitment that falls within the Hornsdale Battery Project where Tesla built its 100MW ESS last year.
