        APS Issues RFPs for More Renewable Energy

        Arizona Public Service Company (APS) announced it is issuing two requests for proposals next month as part of its campaign to bring more solar and wind energy into its portfolio. The two new RFPs will add enough solar and wind resources to power more than half a million homes, about 2,500 megawatts, by 2021, company officials said. Earlier this year, the company also successfully closed two RFPs for large battery installations to store renewable energy to use after the sun goes down.

        LCUS: A New Way to Accurately Measure Energy Storage Costs

        It is often difficult to evaluate the benefits, effectiveness and costs of energy storage technologies. These benefits are dependent on how one uses storage and which technology is used for what purpose. The cost of using an energy storage asset also depends on the initial material and installation costs, as well as how well it is maintained during its service life. These aspects are interconnected and, until now, customers have not been able to easily access this information with a simple test. The new Levelized Cost of Using Storage method combines acquisition costs, O&M, expected use, and service life data into a single meaningful metric to compare different energy storage technologies.

        UL Issues Its First Certification for EV Battery Recycling, Repurposing for Energy Storage

        UL has granted its first certification to UL 1974, the Standard for Evaluation for Repurposing Batteries, to 4R Energy Corporation. Outlining how to sort and grade battery packs, modules and cells that were originally made for electric vehicles (EV) and other applications, UL 1974 helps identify a battery’s state-of-health and introduces ratings to determine the viability for their continued use. Through this process, performance-validated “second-life” batteries can be utilized for energy storage systems to provide a safe, reliable, clean energy source.

        NEC to Install More than 20MW of Municipal Energy Storage Projects in New England

        NEC Energy Solutions has announced six additional energy storage projects of more than 20 MW at municipal power plants throughout New England. The new projects follow the model of the Sterling Municipal Light Department installed two years ago that has saved ratepayers more than $1 million on their utility bills. These energy storage systems reduce costs for transmission and capacity charges, which directly benefit the ratepayers. In Sterling, NEC’s GSS® Grid Storage Solution also provides resiliency for the community in the event of an outage from severe weather and other causes

        China Tariffs: US Industry Group Has 'Deep Concerns'

        The US Energy Storage Association has expressed “deep concern” that additional tariffs slapped on Chinese goods will adversely affect the domestic energy storage industry. The increase in prices in a price sensitive industry “could stymie projects already underway or cancel others altogether”, which could threaten livelihoods. The decision will “have an immediate and adverse economic effect on grid energy storage deployments in the United States,” a statement from the association said.

        Stitching Together the Grid of the Future

        Autonomous Energy Grids is the name of a multifaceted project that the U.S. National Renewable Energy Laboratory (NREL) has created to envision the electricity grid of the future, where output from many decentralized energy sources is managed simultaneously to ensure a secure and consistent energy supply. The concept is focused on smart technology and autonomous communication, based on a series of interconnected microgrids, which communicate with each other and make use of algorithms to continually find the best operating condition in response to constantly shifting energy demand, availability and pricing.

        Buckland Sets a Milestone for Rural Energy Capabilities with New Li-ion Battery

        A few years ago, the village of Buckland in northwest Alaska set a milestone a leader in rural renewable energy when it got two turbines and three solar panels installed. Now, the village has hit an even more ambitious target: unofficially becoming the first village to power itself entirely off of renewable energy stored in recently installed lithium-ion batteries.

        New Type of Electrolyte Could Enhance Supercapacitor Performance

        Supercapacitors, electrical devices that store and release energy, need a layer of electrolyte — an electrically conductive material that can be solid, liquid, or somewhere in between. Now, researchers at MIT and several other institutions have developed a novel class of liquids that may open up new possibilities for improving the efficiency and stability of such devices while reducing their flammability.

      16. Battery Storage Called Into Action As UK Suffers Country-Wide Power Cuts

        Battery Storage Called Into Action As UK Suffers Country-Wide Power Cuts

        Battery storage assets were called into action last week after the UK suffered country-wide power outages following a transmission system stress event. On August 9th, two large generators were disconnected from the UK’s power system almost simultaneously, effectively taking 2GW worth of electricity generation within minutes of each other. That collapse in generation sent the country’s transmission grid frequency to dip, so National Grid, the country’s electricity system operator, called on reserve and flexible generation capacity to respond, with many operators dispatching battery storage capacity to meet National Grid ESO’s calls.
