BORREGO SPRINGS (CNS) - San Diego Gas & Electric will use a .5 million federal grant to upgrade the Borrego Springs microgrid with new technology so it can operate on completely clean energy, the utility announced Friday.The grant, from the U.S. Department of Energy's Solar Energy Technologies Office, will provide funds to purchase smart power inverters, controls and an energy management system. The new devices will improve energy reliability, stabilize the microgrid and help it become 100% renewable.A microgrid is a mini power grid and may include a power source like solar energy, an energy storage component and controls and switches that allow it to operate independent of or parallel to the larger grid. The Borrego Springs microgrid is the first such utility-owned grid in the nation."This grant award comes at a pivotal time for our customers, our company and the next evolution of microgrid technology," said Will Speer, vice president of electric engineering and construction for SDG&E. "Microgrids are one of the tools to enhance community resiliency and maintain energy service during emergencies. With the smart grid technology that we will incorporate into the microgrid, we are confident that this facility can become a model for future clean energy microgrids."The Borrego Springs microgrid began operations in 2013 after SDG&E saw an opportunity to improve energy resiliency for the approximately 2,800 people in Borrego Springs -- a remote desert town subject to extreme heat and monsoonal weather. Until then, the town relied on a single transmission line and distribution circuit for its power. The microgrid is connected to a local 26-megawatt solar field -- owned by a third party -- two battery storage systems, two generators and an ultracapacitor to keep power flowing to the town during emergencies and planned outages on the larger grid."This is great news for Borrego Springs, especially during emergencies like severe weather," said County Supervisor Jim Desmond. "It's important for San Diego County that we continue to move towards a healthier and more sustainable future."Due to unstable voltage conditions and solar energy output fluctuations, it is challenging to operate the microgrid using 100% clean energy. The new inverter, controls and energy management system will help address these challenges and transition the microgrid to a true 100% clean energy facility.SDG&E operates two microgrids -- including the Borrego Springs location -- within San Diego and southern Orange counties. The company is currently constructing four additional microgrids set to be completed in 2020 and 2021 as part of its Wildfire Mitigation Plan. 2697

BOSTON (AP) — A federal appeals court has upheld a district court decision clearing Harvard University of intentional discrimination against Asian American applicants. Two judges on the 1st U.S. Circuit Court of Appeals in Boston rejected claims from an anti-affirmative action group that accuses the Ivy League university of imposing a "racial penalty" on Asian Americans. The decision delivers a blow to the group, Students for Fair Admissions, and moves the case a step closer to a possible review by the U.S. Supreme Court. The group's 2014 lawsuit alleges that Harvard's admissions officers use a subjective "personal rating" to discriminate against Asian Americans who apply to the school. Harvard denies any discrimination.According to the Associated Press, the judges concluded that Harvard does not place outsized emphasis on race. 848

BROOKFIELD -- You may not know the chemical used in your A/C, but that may soon change.The U.S. government will soon stop the manufacturing of a chemical, eating away at the ozone. It is called 'R-22.'R-22 contains chlorine that can deplete the ozone when exposed. This is why it will no longer be manufactured or imported in the United States, starting in 2020. The price has skyrocketed since this announcement.Eble Park Ice Arena in Brookfield, Wisconsin has been using this type of freon since it opened nearly 30 years ago.The facility is owned by the Waukesha County Park System. The county has made about 0,000 in upgrades to this ice rink.Waukesha County Park System Director Duane Grimm said that is a far better deal than switching over to a common chemical used these days, such as ammonia."This will save us money to replace all the chiller plant here we would also have to replace the floor all the piping under the floor," Grimm said. "If we did this you're kind of looking at million to .5 million.This may affect you at home. Air conditioning units before the 2010 cutoff most likely still use the outdated refrigerant, if you spot 'R-22' or 'R-410A' on your compressor unit.You could still buy some recycled R-22 after the cutoff date in two years. It's going to be expensive. An instructor at MATC tells us it will run you about 0 dollars for just 30 pounds.For more information on 'R-22' Freon, visit the EPA's website.  1473
