Final testing under way at expanded Hornsdale big battery in Australia

It has played an important control in providing frequency control and emergency back-up – both critical in helping keep the lights on during major network problems – as well as doing the normal storage thing of energy arbitrage, buying at the lows and selling at the peaks.It is now being expanded to a capacity of 150MW/194MWh, and is adding new services, particularly synthetic inertia, that will allow it to replicate more of the services once exclusive to fossil fuel generators in South Australia, and allow the grid to take another important step towards the shift to the state government target of “net 100 per cent renewables.”The expanded Hornsdale Power Reserve (its official name) is owned by the French renewable energy developer Neoen and located next to the 315MW Hornsdale wind facilities, and got the OK to connect last month. It is now going through testing that allows it to progress through various “hold points” that it can straddle once the market operator is satisfied with the outcome.On Tuesday, in the latest series of tests, the Hornsdale battery did a rapid 270MW flip – from charging at 120MW to discharging at 150MW. It appears to have flipped between the two on several different occasions – at least one of which had an immediate impact on the wholesale price of electricity, pushing it down to the peppercorn price of just above $8/MWh.Those 270MW flips – from the level of discharge to the level of charge – are likely a world record in both speed and extent of the change. And it’s this flexibility of the big batteries such as Hornsdale, and others at Dalrymple North, Lake Bonney, Gannawarra and Ballarat, that is particularly attractive to project owners and valuable to AEMO, the market operator.[Giles Parkinson]More: Tesla big battery sets new record as testing for Hornsdale expansion enters final stagelast_img read more

Pogba waiting for Juventus return

Pogba’s former teammate Andrea Pirlo is now the Juventus coach and they would relish a reunion. FacebookTwitterWhatsAppEmail分享 Paul Pogba is waiting for a return to Juventus in 2021, maybe even in January, by stalling his Manchester United renewal. The 27-year-old had the best form of his career so far in Turin from 2012-16, before the €105m move back to Old Trafford, where he’d been largely ignored in their youth academy. Rumours of a swing back to the Bianconeri have been circling from practically months since he left and nobody has kept those going more than Tuttosport. They place Pogba on the front page of today’s edition, claiming he is stalling a new contract with Manchester United because he is waiting for Juve to step in and make an offer.Advertisement Loading… center_img Promoted Content6 Best 90’s Action Movies From Your Childhood8 Fascinating Facts About CoffeeCouples Who Celebrated Their Union In A Unique, Unforgettable WayBest & Worst Celebrity Endorsed Games Ever MadeWho Earns More Than Ronaldo?Who Earns More Than Ronaldo?Who Is The Most Powerful Woman On Earth?20 Completely Unexpected Facts About ‘The Big Bang Theory’10 Bollywood Celeb Weight Loss Transformations That Will Stun You5 Of The World’s Most Unique Theme Parks5 Of The World’s Most Unique Theme Parks7 Theories About The Death Of Our Universelast_img read more
