| Here (Australia) we've been using large battery parks to offset peak daytime solar into the evening peak demand periods. eg. [1] ( $$ == AUD Australian ) French firm Neoen will build a mega battery in Collie after winning a two-year contract to smooth out energy supply and demand in Western Australia’s south-west grid, which is under strain from soaring midday peak supply from rooftop solar and ageing coal-fired power stations.
The battery, to be constructed from 224 Tesla “Megapacks”, can store 219 megawatts of energy for four hours during the day and discharge it back to the grid during high demand in the evening when solar generation falls.
... UGL, a subsidiary of Spanish-owned CIMIC, has started construction on one of four grid-scale batteries in the south-west of WA. No cost was provided for the battery.
Synergy is commissioning a battery in Kwinana that can store 100 megawatts for two hours that was originally meant to be operating by the end of 2022.
In the May budget, the WA government allocated $2.3 billion for two further batteries.
Synergy will build another battery at Kwinana that can store or discharge 200 megawatts for four hours that is expected to start operating by late 2024.
The cost per megawatt isn't exactly clear in the news article - I'd have to table numbers from primary sources to declutter the journalistic filter.South Australia is also investing in new battery parks [2] (on the back of the success of one of the earliest "city scale" battery parks globally) [1] https://www.watoday.com.au/national/western-australia/tesla-...

Here you're saying it's already happening. And yet your quote is: "will build, to be constructed, has started construction, will build another battery..."
