Tesla testing novel community storage initiative in Western Australia

first_imgTesla testing novel community storage initiative in Western Australia FacebookTwitterLinkedInEmailPrint分享Ars Technica:A community storage pilot project using Tesla batteries went live this week in Western Australia, three months ahead of schedule. The 105KW/420KWh pooled storage will act as a sort of locker for excess power produced by homes with solar panels.The project is an unusual one because it pools battery capacity for homes with solar panels. It was funded by energy company Synergy and government-owned Western Power, which sought 52 customers with solar panels on their homes as participants. The 52 shares of the project were snapped up in two weeks, far more quickly than expected, which accelerated the project’s timeline.Participants will each be allotted 8kWh of storage, which they will “fill” with excess power created by their rooftop solar panels during the day. (This is in theory, of course. Solar-generated electricity can flow back onto the grid, but there’s no guarantee that the battery will be charged with solar-generated electrons.) In the evening, customers will “be able to draw electricity back from the PowerBank during peak time without having to outlay upfront costs for a behind-the-meter battery storage system,” says a press release from the government of Western Australia.The model is similar to that of community solar projects, which have become popular in the US. Rather than spend money on expensive solar panels (or batteries, in this case), homeowners can opt in to a collective project. A managing company will put up the upfront costs and collect payment in installations. The Western Australian community battery project will cost participants AUD$1 (USD$0.73) per day for 24 months, although the participants will be able to opt out of the program at any time. Still, if a customer would normally buy electricity from Western Power in the evening after the sun goes down, participating in a program like this should save them money.More: Tesla battery will power unusual community storage project in Western Australialast_img read more

Three things we learned from the Community Shield

first_imgNarrow marginsWhen Kyle Walker leapt acrobatically into the air to hook Mohamed Salah’s header off the goalline in the final seconds, it was a vivid demonstration of the narrow margins that are sure to settle the battle for supremacy between Manchester City and Liverpool this season.Manchester City’s Kyle Walker clears off the line to deny Liverpool’s Mohamed Salah © AFP / Adrian DENNIS“I’m a defender. I stop goals,” Walker said. “It starts off the season. We can start our momentum, and hopefully we can replicate what we did last season.”Walker’s incredible clearance, which allowed Pep Guardiola’s team to eventually win on penalties, was reminiscent of City team-mate John Stones’ remarkable stretch to block his clearance from deflecting into his own net against Liverpool last season.Stones managed to stop 11 millimetres of the ball from crossing the line, setting the stage for a 2-1 City win that played a key role in their successful title defence as they held off Liverpool by one point.That title race was only concluded on the last day of the season and required City to reel off a blistering sequence of victories to stop Liverpool, beaten just once all season in the league, winning their first English title since 1990.With little to separate treble winners City and European champions Liverpool in Sunday’s ferociously-fought ‘friendly’, the expected battle for the Premier League title between the rivals is likely to go down to the wire once more.Sterling, Salah shake off rustLiverpool’s Mohamed Salah led the attack at Wembley © AFP / Ian KINGTONRaheem Sterling and Mohamed Salah were two of the driving forces behind Manchester City and Liverpool’s success last season and they look set to lead the way again after the star forwards were at the heart of the best moments at Wembley.Sterling always shines at Wembley for club and country and the England winger, who started up front before moving to the flanks after Leroy Sane’s injury, was a constant menace with his pace and movement.He opened the scoring with a close-range finish in the 12th minute, but showed a brief sign of rust when he wasted a chance to put the game out of Liverpool’s reach in the second half as he stumbled when clean through on goal.It is likely to be a rare slip from Sterling and the same will surely be said of Egypt’s Salah.While some might be concerned Salah failed to hit the target from a host of opportunities, he was by far Liverpool’s most dangerous forward and on another day he would have had a hat-trick.Schedule stressManchester City manager Pep Guardiola and Liverpool boss Jurgen Klopp are united in their belief that football’s schedule makers are putting their players at risk with their unrelenting fixture list.Jurgen Klopp and Pep Guardiola are united in their contempt for the demands placed on their players © AFP / Ian KINGTONLiverpool were without Senegal winger Sadio Mane as he rested after the Africa Cup of Nations, while Manchester City didn’t have Algeria’s Riyad Mahrez following the same tournament.Several other City and Liverpool stars including Mohamed Salah and Sergio Aguero have only recently returned to training after their international commitments in what is dubiously called the ‘close-season’.In the circumstances, both teams deserve credit for producing tenacious performances after so little time to recover.But with the Premier League starting next Friday — earlier than any of the other major leagues — when Liverpool host Norwich, Klopp once again made it clear he believes the authorities are being unfair on the players by having such a small break before the domestic season begins.And Guardiola, whose team open their league season at West Ham on Saturday, totally agreed, slamming a “crazy” schedule he hopes won’t detrimentally affect City’s title defence.0Shares0000(Visited 2 times, 1 visits today) 0Shares0000Manchester City’s Gabriel Jesus celebrates after converting the winning penalty in the Community Shield © AFP / Adrian DENNISLONDON, United Kingdom, Aug 5 – Manchester City won the Community Shield with a 5-4 penalty shoot-out win over Liverpool after a 1-1 draw at Wembley on Sunday.Here, AFP Sport looks at three things we learned from the annual curtain-raiser to the English top-flight season:last_img read more
