      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.
