After working with Tesla’s Australia battery, wind company wants more batteries
In the first half of 2018, energy sales from Tesla's 100MW/129MWh battery installation at the Hornsdale Wind Farm in South Australia brought in €8.1 million in the first half of 2018.
€6.7 million ($7.8 million) of that revenue came from frequency control services. Another portion of the revenue was generated through a 10-year contract that Neoen has with Australian grid managers to purchase AUD $4 million (€1.4 million, USD $2.9 million) worth of electricity per year. The contractual revenue is before interest, tax, depreciation, and amortization, however, so actual numbers may be higher or lower.
The battery itself cost €56 million ($66 million), documents say.
