U.S.’ largest battery storage system begins operation in California, much more in the pipeline

first_imgU.S.’ largest battery storage system begins operation in California, much more in the pipeline FacebookTwitterLinkedInEmailPrint分享S&P Global Market Intelligence ($):Power plant developers LS Power Group and Terra-Gen LLC added two big new lithium-ion battery stations to the California ISO’s expanding portfolio of electrochemical energy storage in June, marking the start of a potential sevenfold jump in battery resources on the state’s primary power system in 2020.That includes the initial 62.5-MW phase of LS Power’s planned 250-MW Gateway Energy Storage Project, which came online June 9, one week after 16.5 MW of battery storage at Terra-Gen’s Mojave 90 wind-storage hybrid project entered service, CAISO data shows.Located next to the natural gas-fired Otay Mesa Generating Project in San Diego County near the U.S.-Mexico border, LS Power’s Gateway system is now the largest operational battery storage facility in the United States, according to S&P Global Market Intelligence data. The previous biggest system, LS Power’s 40-MW Vista Energy Storage facility, is also in San Diego County.“Utility-scale battery energy storage projects such as LS Power’s Gateway and Vista projects are effective ways to enhance grid reliability and reduce costs to consumers by shifting energy from midday solar production hours to the evening peak,” John King, LS Power’s executive vice president for renewables, said in an email.Battery storage is a critical part of California’s strategy to replace retiring natural gas generation while balancing rising volumes of variable renewable energy resources, especially solar power, that are increasingly curtailed in the middle of the day amid power oversupplies.Together, the two new projects boosted energy storage on the state’s primary transmission system to roughly 215 MW, from 136 MW at the start of the year, a CAISO official said. If all of the energy storage projects seeking 2020 interconnection remain on track, the grid operator expects to have roughly 923 MW of battery storage online by the end of 2020.[Garrett Hering]More ($): Most powerful U.S. battery system charges up in Calif. storage surgelast_img read more

O’Connor happy to win ‘arm wrestle’

first_imgLeinster head coach Matt O’Connor was happy to see his side come through a real ‘arm wrestle’ with Harlequins as they edged out the Londoners 14-13 in Saturday’s European Champions Cup Pool 2 match at the Aviva Stadium. Press Association “I’m just frustrated,” O’Shea said. “You come to win. We didn’t come to make up the numbers and credit to our fellas. First half, they tackled their socks off because we didn’t hold the ball. Second half they showed huge mental strength and could have nudged a pretty historic win but we didn’t. “You are bound to be disappointed after a game like that. First half, 11-0 down, we missed a couple of opportunities ourselves but didn’t hold onto the ball if we are being honest. Our defence was heroic, but we didn’t hold onto the ball as much as we should. “A couple of TMO decisions (went against us), but that’s life. It’s small margins. We are in control of our own destiny but it’s a long way to go. The boys are very disappointed.” The Blues had appeared on course for a more comfortable victory when leading 11-0 at the break, as man-of-the-match Ian Madigan landed two penalties and Isaac Boss picked off an opportunist try in the right corner. Harlequins used their superior scrum to force the issue in the second period as full-back Mike Brown crossed for a try approaching the hour mark and Tim Swiel, who deputised at fly-half for the injured Nick Evans, added eight points with the boot. But Leinster had the final say thanks to a decisive 71st minute penalty from Madigan. O’Connor said: “I wouldn’t say (we) escaped (with the result), no. It was tight, it was an arm wrestle. It was very, very intense, a high quality game between two very committed sides. Escaped is a very strong word. “If we had executed a little bit better we could have been out of sight at half-time. That was our doing. They came back very hard at us in the second half – we were a bit inaccurate early doors and, as a result, they got their tails up and got a bit of momentum. “We would have liked to get a little but more out of tonight. We would have liked to be more accurate and get something more in London last weekend but there’s two games to go (in the pool stages) and we’ve given ourselves a chance.” The win leaves Leinster level with Harlequins on 13 points, with Conor O’Shea’s side just ahead on scoring difference. “If we’re good enough and we can get maximum points out of those two remaining games, or more points than Quins, we give ourselves a chance (of reaching the quarter-finals),” O’Connor said. “That’s not a bad place to be with bodies coming back into the group.” Harlequins director of rugby O’Shea was left frustrated after his charges only collected a losing bonus point from their trip to Dublin. As a collective, Quins performed to a higher level than Leinster but failed to clinch a precious away win that would have put them in clear control of the pool. They also ended the game down to 14 players following a late yellow card for lock Charlie Matthews, who was seen to raise his hand into Dominic Ryan’s face. last_img read more
