Final testing under way at expanded Hornsdale big battery in Australia FacebookTwitterLinkedInEmailPrint分享Renew Economy:The Tesla big battery at Hornsdale in South Australia is entering the final testing of its expanded capacity, and is achieving some significant new records and milestones that would be expected when the world’s biggest lithium ion battery gets even bigger.The Hornsdale battery set a world record for a lithium-ion battery installation when it was installed in late 2017 with capacity of 100MW/129MWh. 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 stage
Topics : “This year has been unprecedented for the world and we are proud that Formula One has come together in recent months to return to racing in a safe way,” Formula One Chairman Chase Carey said.Negotiations over a new Concorde Agreement had been put on hold due to the COVID-19 crisis that hit the teams and sport financially.”We said earlier in the year that due to the fluid nature of the pandemic, the Concorde Agreement would take additional time to agree and we are pleased that by August we have been able achieve agreement from all ten teams on the plans for the long term future of our sport,” Carey added.”The new Concorde Agreement, in conjunction with the regulations for 2022, will put in place the foundations to make this a reality and create an environment that is both financially fairer and closes the gaps between teams on the race track.”Formula One’s three oldest and most successful teams — Ferrari, McLaren and Williams — were the first to sign with rights holders Liberty Media and the FIA on Tuesday, with the seven other teams following suit on Wednesday.”Over its 70 year history, Formula One has developed at a remarkable rate, pushing the boundaries of safety, technology… to the absolute limit and today confirms that an exciting new chapter in that history is about to begin,” FIA President Jean Todt said. Formula One’s 10 teams have committed to the sport until at least the end of 2025 by putting their signatures to a new commercial ‘Concorde Agreement’.The current agreement, which sets out the terms under which teams race and the share of revenues, is set to expire at the end of 2020.Formula One and the governing FIA on Wednesday said in a joint statement the agreement will secure the long-term sustainable future for the sport and reduce the financial and on track disparities between the teams.
Zarkandar and Saphir du Rheu are two of the favourites for the third of today’s Grade Ones.Action is underway at Prestbury Park today with the J-L-T Novice’s Chase at 1.30. Michael O’Leary could well be presenting himself with the trophy for the Ryanair Chase today.That’s one of the feature races on day three of this year’s Cheltenham Festival, and the Gordon Elliott-trained Don Cossack – owned by O’Leary – is the pre-race favourite.Paul Nicholls could follow yesterday’s treble with victory today in the Ladbrokes World Hurdle.
