Battery energy storage system BESS is a global energy requirement of the future. However, it cannot be deployed unless the industry takes a comprehensive approach to life safety (Fire) emergencies. Energy storage is an essential building block of the future for the grid. Storage facilities have raised serious safety concerns for life safety. Failing to address fire life safety concerns would not only hinder the energy storage industry, but also leave us exposed to unacceptable failures. The question is asked what is the industry doing to reduce fire risks?  By being clear about the challenges we face, developing our life safety standards and working more closely with regulators, the energy storage industry can satisfy safety concerns, streamline project development, and ensure the energy grids receive the support from battery storage that they desperately need. Part of the answer is layers of safety in BESS systems. Layers starting with the designs of enclosures, auxiliary systems including fire alarm(FACP), BMS, EMS, and disconnect systems, to the elimination of cell to cell propagation. https://lnkd.in/e5MExak5 #nfpa844 #UL9540 #AHJ #energystorage #BESS #ESS #batteryenergystorage

🌞 Innovations in Energy: California's Journey Toward a Sustainable Future. As we head into what will probably be another temperature record-breaking summer in 2024, I was looking back at some of the innovations and growth that California and #CAISO have been showing the energy industry in the past few years. #California, a renewable energy leader, aims for 100% clean electricity by 2045. With CAISO, it's integrating 35,000 MWs of renewables into the grid, 9,000 MWs added in the last 3 years. Some interesting facts about California & CAISO: ☀ California has been a #solarenergy leader, but Texas has rapidly increased its utility-scale solar capacity since 2019, nearly doubling it from 2019 to 2020 and again from 2020 to 2021. This growth is due to lower construction and operating costs of solar power plants, contributing to their expansion on the Texas network. Unlike California, where policies have largely driven solar growth, Texas market dynamics have played a central role, highlighting economic shifts in the #energysector. 🔋 In California, battery energy storage systems helped prevent #blackouts during the 2020 and 2022 heat waves. In August 2020, when demand peaked at 46.8 GW, power outages occurred. However, during the September 2022 heat wave, despite higher demand reaching 51.4 GW, new battery energy storage systems provided 3.4 GW of peak generation, helping prevent blackouts. The increased battery capacity introduced between 2020 and 2022 has had a significant impact on solving grid problems. 🌱 In 2022, California enacted significant regulatory reforms aimed at streamlining the process of building thousands of megawatts of clean power. The state has a comprehensive #electricity supply and energy storage planning process in place to help accelerate new clean energy projects. 💲 California's $7.3 billion grid modernization plan, approved by CAISO, is key to reaching the state's #carbonfreeenergy goal by 2045. It includes new high-voltage lines to connect clean energy sources, potentially lowering electric bills. This is crucial as more areas discourage natural gas and promote #cleanenergy. 🔄 CAISO manages California's energy grid, balancing supply and demand while integrating renewables. #BatteryStorage success shows the importance of investing in #renewables for grid reliability globally. As we look to the future, California's energy landscape serves as a testament to the power of innovation, resilience, and the collective effort toward a sustainable and reliable energy future. Powin remains committed to supporting CAISO in improving network reliability and resilience. We currently have 1,300 megawatt-hours (MWh) commissioned and 3,180 MWh under construction in California. Our advanced battery energy storage solutions, coupled with our commitment to innovation and collaboration, will help ensure a secure and sustainable energy supply in California and beyond. 🌟 #RenewableEnergy #GridReliability #Sustainability #CAISO

While heading to Sedona and back from the beautiful Grand Canyon/Lake Powell area for spring break last month, my daughter and I had a chance to overfly the battery energy storage system (BESS) installation at the Desert Center solar farm in California.   This 550MW solar farm began operations in late 2014, is jointly owned by NextEra Energy Resources, GE and Sumitomo Corporation, and is said to have long-term PPAs in place with Pacific Gas and Electric Company and Southern California Edison (SCE). It can provide enough energy to power 160,000 average California homes while preventing 614,000 metric tons of carbon dioxide emissions annually.   While a 230MW/920MWh BESS facility was already commissioned in 2021/22, the addition of another 300MW BESS, as approved by Bureau of Land Management and reported by Michelle Van Der Linden just last year, could not come at a better time! With 4-hour duration, it will enable shifting of the renewable energy generated by this solar farm to peak demand hours, offering our local California Utilities further grid resiliency while also addressing a reduction in GHG emissions.   As pointed out recently by Mark Jacobson, California ran on 100% renewables power (for a few hours each) on multiple days last month, and according to some recent estimates by the California Energy Commission, the state could require up to 37GW of energy storage by 2045 to meet all its needs from carbon-free sources. Just last month, Governor Gavin Newsom also announced that California had hit the 10GW mark for installed battery capacity, and with successful commissioning of more such BESS units, the state will once again be leading the way in this new era of energy resiliency and environmental stewardship.   https://lnkd.in/gpG8jdma   #solar #renewables #batteries #california #thefutureiselectric

Battery storage offers a solution to one of renewable energy's most significant challenges. 👉 Intermittency. Solar and wind power is abundant and sustainable. But is not always available on demand. So store excess energy during peak production times. Then release it when needed. Projections indicate an 89% surge in U.S. battery storage capacity to exceed 30 gigawatts (GW) by the end of 2024 Leading this change are California and Texas with the five largest new U.S. battery storage projects scheduled for deployment in 2024 and 2025: - Lunis Creek BESS SLF (Texas, 621 MW) - Clear Fork Creek BESS SLF (Texas, 600 MW) - Hecate Energy Ramsey Storage (Texas, 500 MW) - Bellefield Solar and Energy Storage Farm (California, 500 MW) - Dogwood Creek Solar and BESS (Texas, 443 MW) California currently leads with 7.3 GW followed by Texas with 3.2 GW. Globally, we're seeing a decisive move towards battery plants over gas power plants. They offer a more flexible, efficient, and sustainable solution for managing the intermittency of renewable energy sources. How do you think this will impact the national energy grids? #innovation #technology #energy #sustainability #electricalengineering Source: US Energy Information Administration ASEC ENGINEERS - Engineering your success, delivering precision and innovation in every project since 1991.
