Now it is on to a new mission: saving that energy for later.Large-scale solar power plants coupled with energy storage systems are multiplying in the U.S., as developers and grid operators seek to smooth the variable output of solar plants by storing the electricity they produce for peak power demand in the evening. At least 51 such hybrid systems 1 MW and larger are online or planned, according to S&P Global Market Intelligence data. Operational systems total 783 MW of solar capacity tied to 492 MW of storage for various periods of time, while planned projects account for 3,228 MW of solar integrated with 2,888 MW of storage.Many of these solar-plus-storage projects are concentrated in the Southwest. Hawaii and the Northeast also have multiple projects planned or underway. Beyond known projects with identifiable developers, many more solar-plus-storage power plants are earlier in the development process. Grid operator interconnection queues and recent responses to utility requests for proposals show several thousand megawatts of additional potential.In response to Xcel Energy Inc.’s recent request for proposals, for instance, developers pitched 57 projects in Colorado for more than 10,000 MW of battery-backed photovoltaics. The California ISO’s generator interconnection queue, as of May 24, showed 16 projects coupling 3,340 MW of solar PV with 2,532 MW of batteries. Another 14 solar-plus-storage projects with a combined maximum output of more than 5,000 MW were exploring interconnection in Arizona Public Service Co.’s territory, as of April 4. Additional large-scale battery-backed solar projects are under study in the ISO New England, New Mexico and PJM Interconnection.“I see a future with more battery and solar combinations,” Jeff Burke, director of resource planning at APS, said in an interview.On new energy frontier, solar-plus-storage plants proliferate New solar plants equipped with electricity-storage capacity are proliferating across the U.S.
Paul Deegan believes star mare Midnight Soprano could take her game to another level this season ahead of her return to action in the Cork Racecourse Mallow Noblesse Stakes. The six-year-old won five races, including two Listed prizes, during a superb 2012 campaign and looks to have a fine opportunity to open her Pattern-race account in this mile-and-a-half Group Three. From what he has seen at home, Deegan thinks there are signs Midnight Soprano is in better shape than she has ever been. “It’s a good Group Three but she won’t mind the ground and gets the trip well. She’s fit and she’s well and I’m looking forward to getting her started. She has been an absolute star for us over the past few seasons, a beautiful natured mare and a pleasure to have in the yard,” said the trainer. “She has done better over the past winter than any before, and has really strengthened this time around. Hopefully it brings about another bit of improvement in her. “She won the Saval Beg on really soft ground last year but she seems to go on most types of ground. Her sister (Celtic Soprano) got a bit sharper as she got older and this mare might be the same. A mile and a half is probably her optimum trip. She takes very little work and gets naturally fit. Her last few pieces of work have been very pleasing.” The Kevin Prendergast-trained Majenta takes a significant step up in class, just a week after winning in handicap company at the Curragh. Prendergast said: “She’s run three times and won twice, and we’d like to get her some black type. Her owner Joerg Vasicek is a breeder and he got the record price of 215,000 euro at the Goffs Land Rover Sale for a three-year-old during the week. “She’s come out of the Curragh race very well. It looks a hot contest but she’s getting weight-for-age, and we’ll be hoping to get her into the placings.” A field of 10 has been declared, with Dermot Weld’s Ribblesdale heroine Princess Highway the highest rated filly in the field. There are two challengers from Britain in Ralph Beckett’s Cubanita and Testosterone from Ed Dunlop’s yard. Beckett said: “She’s in good form and I think the trip and ground should be in her favour, which is why we’re travelling over with her. She’s obviously got her work cut out to beat Dermot Weld’s filly, but she’s in great shape and we’ll give it a go.” Press Association
