Capital Dynamics, Tenaska join forces to develop 2GW of battery storage in California

first_img FacebookTwitterLinkedInEmailPrint分享PV Tech:Asset management firm Capital Dynamics has signed a deal with Nebraskan independent power producer Tenaska to develop nine battery energy storage system (BESS) projects located in California’s highest electrical load centres.The BESS projects will be designed to deliver power resources to manage high-demand conditions caused by heat waves, supply shortages and growing local power supply deficiencies in the Bay Area, Los Angeles and San Diego areas that cannot be reliably served solely by intermittent renewables, the companies said.Struck through Capital Dynamics’ Clean Energy Infrastructure business, the deal will see enable the provision of approximately 2GW of clean energy through the nine projects into the California Independent System Operator (CAISO) market.Benoit Allehaut, managing director of the Clean Energy Infrastructure team, said California is poised for “significant growth” in energy storage demand as a result of its “robust” clean energy goals. Indeed, the state announced plans in March to add 25GW of renewables by 2030. “We are excited to join with Tenaska to build high-quality battery energy storage facilities to help integrate renewables and reinforce CAISO grid reliability and resilience,” said Allehaut. “We hope to quickly contract resource adequacy with utilities and CCAs to grow this portfolio.”The move builds on other partnerships between Capital Dynamics and Tenaska. Last month, they agreed to develop 24 solar projects totaling 4.8GW, following on from a previous collaboration for 14 PV projects with approximately 2GW in the US Midwest.[Jules Scully]More: Capital Dynamics and Tenaska partner for 2GW of battery storage in California Capital Dynamics, Tenaska join forces to develop 2GW of battery storage in Californialast_img read more

COVID-19: ‘Baba Ibeji’ in no hurry to return to action!

first_img The event lost a bit of its appeal, but eight-time Australian Open champion Novak Djokovic did well to win a fifth crown in Dubai on the leap day of the year. That incidentally turned out to be the final competition on the ATP Tour before being shut at least till the middle of July. Wimbledon has been cancelled for the first time since World War II and Nadal’s favourite Grand Slam at Roland Garros has been pushed back for a September 20 start. “I am not playing tennis, I do not have a court at home and I miss it a little,” Nadal admitted to Federer. “I am sticking to my physical routines. From the gym of my academy, they were able to bring me some machines when lockdown began – so I try to work a little in the morning, a little in the afternoon. It is very important to have both the head and the body focused and it is what I am trying to do at all times,” he added.

Tennis great and Swiss icon Roger Federer popularly called ‘Baba Ibeji’ his Nigerian fans, has admitted to his friend and arch rival Rafael Nadal that he is in no hurry to make a return on Tour. Two of the greatest tennis exponents of this generation caught up in a live Instagram chat late Monday in a freeflowing and candid chat even as Covid-19 continues to force lockdown.“There is no stress, no rush. If there is anything positive (about being in lockdown) that’s the only thing really. I just want the knee to be good, it doesn’t matter when I return,” Federer told the Spaniard. “I’ve been hitting a bit against a wall, (doing) rehab with the knee. It’s OK, I had a really good first six weeks, then it was a bit slower, now it’s getting better again, but I have plenty of time,” the Swiss ace said, indicating that he’s not keen on forcing a hurried comeback on the ATP Tour.Federer underwent knee surgery in the middle of February just when he was scheduled to travel to Dubai for the Dubai Duty Free Men’s Open.

How wind patterns drive balls to right field at SU Softball Stadium

first_imgMike Bosch credits a groundhog for why there have been so many home runs hit to right field at SU Softball Stadium. The groundhog, which he calls the team’s mascot, lives beyond the right-field fence and occasionally scurries around the bleachers for food. Its mere presence attracts balls its way, said Bosch, Syracuse’s head coach.However, there are more logical ways to explain the jet stream that has helped send 29.6 percent of home runs hit this year over SU’s right-field fence. It’s not just that there are a handful of powerful left-handed hitters on the team. Seventy-seven percent of Syracuse’s home runs this year have come from right-handed bats. A dominant westerly wind, a southerly wind blocked by Tennity Ice Pavilion and air pockets created by surrounding areas have contributed to the right-field power alley. These factors will likely come into play again on Wednesday, when Syracuse (23-18, 8-9 Atlantic Coast) hosts Colgate (7-21, 3-5 Patriot) in a doubleheader. “There really is a big difference, whether it’s righty or lefty, in that general right-center, right-field way,” SU assistant coach Alisa Goler said. “If it gets up in the air and comes off the bat pretty hard, in my opinion, I usually assume it’s going to go out. That’s how big of a difference it is.”AdvertisementThis is placeholder textThe right-field jet stream was evident most recently in last Wednesday’s doubleheader between SU and Canisius. The Orange smacked three home runs to right or right-center field. In game 2, Corinne Ozanne didn’t appear to get all of an outside pitch, but she sent it over the right-field fence anyway. A man in a Canisius jacket turned to his right and asked, “What is this, a home run derby?” Jon Nese, associate head of the undergraduate program in meteorology at Penn State University, examined Syracuse, New York, wind roses, or diagrams. He also looked at the SU Softball Stadium and surrounding area on Google Maps. He explained three reasons for why balls carry out to right field. First, the dominant wind in Syracuse is westerly, or coming from the west. SU Softball Stadium faces north-northeast, so the sun isn’t in the batter’s view. This means the wind blows across the field and out toward right field, which sits in the east. Most of the time, the outfield flags in left field indicate the wind is blowing in, toward home plate. Nese said while the flags are not wrong, the dominant wind in Syracuse is still westerly. Second, Nese said southerly winds are blocked by Tennity Ice Pavilion, which looms right behind the first base dugout. Nese said the pavilion is just high enough to block southerly winds that would blow from the South and push balls toward left field. “I strongly believe that ice pavilion plays a major role in lessening the impact of a south wind blowing balls out to left field,” Nese said. “I would not put too much stock in what those flags are showing.”The third reason for the right-field jet stream lies in what surrounds the stadium. In addition to the trees, there is a parking lot behind the left field fence. On a sunny day, the impact of the sun on the asphalt in the parking creates small-scale effects that influence the flags, Nese said. The air over the parking lot rises because it tends to get warmer than air over, say, nearby dirt. To fill the void over the parking lot, air from surrounding areas — SU Softball Stadium — tends to move toward the lot. This creates small-scale air movements that could impact the flight of balls, Nese said. “Small scale variations in the wind are very much related to the surface covering, whatever is covering the surface,” Nese said. “For example, an asphalt parking lot will tend to absorb sunlight better than nearby dirt.”Goler first noticed the jet stream last fall because the team’s lefties, excluding Sydney O’Hara, are not power hitters. Yet when they would pull the ball, it would get out in a hurry. The jet stream has existed since at least 2009, Jenna Caira’s freshman year at Syracuse. Caira, SU’s all-time leader in wins, strikeouts and earned run average, said while most home runs to the left side of the field would barely clear the fence, right field was a different story.“It just carried for days,” Caira said. “It’s probably still going. That’s how hard it would go out and carry.” Syracuse has become a power-hitting team — the Orange is 44th in Division I in home runs per game with .95. But even on balls that stay inside the park, the jet stream can turn what would otherwise be routine fly balls into extra-base hits. SU assistant coach Kristyn Sandberg acknowledged this fact and said she and Goler teach their hitters how to make the most of the stream. They teach right-handed hitters to work the right-center gap and lefties to pull the ball with runners on. “It’s a nice home field advantage,” Goler said, “but you just got to hope nobody else hits it in the air over there.” Comments Facebook Twitter Google+ Published on April 18, 2016 at 9:31 pm Contact Matthew: mguti100@syr.edu | @MatthewGut21last_img read more
