        Batteries Edge Out Natural Gas Peaking Plants in Arizona RFP

        A recent announcement by electric utility Arizona Public Service could mark the tipping point in the way utilities think about building resources to meet peak demand. Historically utilities built “peakers,” usually gas turbines fueled by natural gas, to meet spikes in demand, but in recent solicitations Arizona Public Service chose battery storage projects over peakers. Late last month, APS, the largest utility in the state, said it plans to add 850 MW of energy storage by 2025, including 200 MW of stand-alone energy storage projects that competed and won against gas-fired peakers.

        Rocky Mountain Power Proposes 600-Battery Apartment Building Among Trio of Utah DSM Projects

        Rocky Mountain Power has asked the Public Service Commission of Utah for authorization to implement three 'innovative utility programs' it says were authorized by the Sustainable Transportation and Energy Plan (STEP) Act of 2016, focusing on transportation, storage and grid management. The programs include a battery demand response project in a 600-unit multi-family development, and an intermodal transportation charging and power balancing system to be developed with the Utah State University’s Sustainable Electrified Transportation Center and the state's transit authority. RMP's application is its fifth tranche of proposed STEP programs, and the utility said the funding for the programs has already been earmarked.

        SaltX starts groundbreaking pilot plant tests in Berlin

        SaltX Technology is a Swedish company that developed EnerStore, a technology whereby energy can be stored in salt indefinitely to provide heating or cooling. During the summer of 2017, SaltX, and Vattenfall initiated a collaboration to construct a large-scale energy storage based on SaltX solution with nano-coated salt. Now - one and a half year later - the plant has been installed, tested and commissioned at Vattenfall's combined heat and power plant, Reuter-C in Berlin. The next step for the parties is to perform actual testing of the energy storage for a number of months to evaluate both technology and functionality.

        The competition for the title of "world’s largest virtual power plant" has largely been focused on residential solar-battery systems, like those being deployed by contenders like Australia’s AGL or Vermont’s Green Mountain Power. But according to AMS, formerly known as Advanced Microgrid Solutions, the world’s biggest VPP is already up and running in the form of the 27-megawatt, 142-megawatt-hour fleet of batteries it’s managing today at commercial and industrial sites across the territory of utility Southern California Edison. On Tuesday, the San Francisco-based startup announced that its systems delivered more than 2 gigawatt-hours of grid services over their first year of operations.

        Germany Looks to Put Thermal Storage Into Coal Plants

        The German Aerospace Center is investigating whether Germany’s coal plants could be reused as energy storage assets. The research body, which has a track record in concentrated solar power development, is planning a pilot that will involve ripping out the boiler from an old coal plant and replacing it with a molten salt thermal storage tank that will be heated using excess renewable energy. If the concept works, then advocates say it could help safeguard coal generation jobs while giving Germany tens of gigawatts of storage capacity for renewable energy load-shifting on the German grid.

        How Three Battery Types Work in Grid-Scale Energy Storage Systems

        Storage systems may support renewable projects, such as wind and solar, by regulating the variability of these energy sources and increasing reliability to deliver on-demand power. Picking an ideal battery application and designing the best system and operating strategy can make or break the economics of an energy storage project. There are performance-specific features and applications for each of these battery systems, however, the goal of energy storage developers is the same: to choose a battery application that will ensure an affordable, reliable, and efficient energy-storage system.

        California’s Wildfire Threat Could be an Opportunity for Clean-Energy Microgrids

        California’s biggest investor-owned utilities are expected to de-energize power lines more frequently this year to stop them from igniting fires when the weather is dry and windy. It’s one of the fastest and cheapest ways for utilities to keep wildfires from sparking. But there’s an obvious downside: Whole communities can go dark for hours or even days. With those concerns in mind, some energy companies are urging state officials to incentivize microgrids and smaller standalone energy systems, such as rooftop solar paired with batteries, in fire-prone communities. Those technologies, the companies say, could help keep the lights on during preemptive power shutoffs.

        Research of Large Energy Users Highlights the Possibilities for Storage and Flexible Loads

        The current energy system is likely to constrain the continued expansion of  renewable uptake by businesses. In wholesale markets, solar PV is hollowing out demand in the middle of the day, which is lowering the price and business case for new solar installations. On distribution networks, large volumes of solar power can push infrastructure beyond operating limits, requiring increased network investment. Luckily new solutions use storage and load flexibility to locally optimize demand and supply, such as through efficiency improvements, renewable energy, battery and existing non-battery thermal storage, and the use of demand management controls to optimize integration.

        Could Pumped-Storage Hydro Help Southwest Virginia Reclaim its Role as an Energy Hotbed?

        Southwest Virginia lawmakers are looking to pumped-storage hydro and renewables to make the state’s coalfields an energy hotbed again. The General Assembly approved a bill this month to create a state authority that could win grants and other funding to fuel energy technology research and development. The legislation, which still awaits signature by Gov. Northam, carries no funding mechanism but erects a structure for the state to support an array of R&D activities in the coalfields. The legislation specifically names as priorities pumped-storage hydropower — a clear reference to Dominion Energy’s plans to build such a facility — as well as the development of renewable energy generation on brownfield sites, including abandoned mines. The bill also directs the authority to support workforce training and development of a Southwest Virginia Energy Park.
