    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.

    ESA Calls for Robust Evaluation of Benefits in New Jersey Storage Study

    ESA filed comments in response to a notice requesting comments by the Board of Public Utilities in support of the New Jersey energy storage cost benefit study called for by the 2018 Clean Energy Act. Staff is seeking comments in support of regulatory analysis and policy recommendations in the report. In our comments, ESA outlines the potential benefits of energy storage in New Jersey and provides guidance on which benefits should be included in the analysis; describes the current regulatory and market barriers to the deployment of energy storage systems in New Jersey; and includes a framework that allows for all storage technologies of all durations and types to support New Jersey’s ambitious clean energy and climate goals.

    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.

    How Residential Energy Storage Could Help Support the Power Grid

    The growth of battery storage in the power sector has attracted a great deal of attention in the industry and media. Much of that attention focuses on utility-scale batteries and on batteries for commercial and industrial customers. While these larger batteries are critical segments of the energy-storage market, the rapid growth of residential energy storage is outpacing expectations, and these household systems will likely become important assets sooner than many expect. The growth trajectory and potential value of these household systems to customers and the power grid warrants a closer look.

    Storing Energy By Heating Stones To 600 Degrees — Could Power Whole Country For Hours

    The Danish minister of education and research attended the official inauguration of a giant pilot facility that will use 600 degree hot stones to store energy. High-temperature thermal energy storage uses cheap, non-degradable, and environmentally friendly storage materials combined with known charging and discharging technology to reduce the cost and increase the efficiency of energy storage.

    Advanced Microgrid Solutions Breaks 2 Gigawatt-Hours in Grid Services

    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.

    Arkansas Utility Contracts NextEra to Build 100MW PV Project with 30MW Storage

    NextEra Resources will build a 100MW solar farm for Entergy Arkansas, to include 30MW of battery energy storage, as Entergy seeks to build out solar capacity in the state. Entergy Arkansas said yesterday that it has contracted NextEra Resources, one of the three main NextEra power producer companies along with Florida Light & Power and NextEra Energy, to build the project near Searcy, in White County Arkansas. Scheduled for completion in 2021, Entergy will own and operate plant once it has been designed and built by NextEra, bringing the utility’s solar generation capacity in its service area up to 281MW.

    Trio of Federal Energy Storage Bills Avoid Tax Credits

    Three bipartisan energy storage bills were introduced in Congress last week, but none would provide investment tax credits, which industry has sought to increase the competitiveness of the technology. The three storage bills, which focus on opportunities for loans and research in energy storage, come amid rising interest in the technology, with an increasing number of state targets, a new bipartisan storage caucus in the U.S. House of Representatives and increased funding in the President's latest budget request.

    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.
