Tesla CEO Elon Musk has said that the company is already achieving “good margins” on the residential Powerwall product, but that “some additional work is needed” for its utility-scale Megapack to do so.

While it is better known for putting lithium-ion batteries in phones, tablets and computers, consumer technology company Apple said it is building a 240MWh battery energy storage system (BESS) at a solar PV plant in California.

Developer Fotowatio Renewable Ventures (FRV) has unveiled the second utility-scale battery project in its “strategic plan to develop energy storage projects globally”.

About a year after unveiling what is thought to be the first large-scale Tesla Powerpack battery project in the Balkans, Slovenian energy services company NGEN has confirmed that it has completed its second, even bigger project.

10MW / 20MWh of Tesla Megapacks used for Alberta’s first-ever large-scale battery energy storage system have gone into action as TransAlta Renewables announced the project has reached commercial operation.

Australia’s national Clean Energy Finance Corporation (CEFC) has said it will commit AU$50 million (US$34.14 million) to help fund expansion of landmark Hornsdale battery project in South Australia.

NGEN, a developer based in Slovenia, has celebrated the installation of a 22MWh grid-scale battery energy storage system (ESS) supplied by Tesla in what is thought to be the product’s first deployment in the Balkans.
