        APS Plans to Add Nearly 1GW of New Battery Storage and Solar Resources by 2025

        The Arizona power grid has a unique set of challenges, which it turns out solar and energy storage are particularly well suited to address. Arizona Public Service, the state’s largest investor-owned utility, announced Thursday morning that it will add 850 megawatts of battery storage and at least 100 megawatts of solar generation by 2025. That amounts to nearly 1 gigawatt of new clean energy technology, to be obtained through a combination of newly completed and upcoming procurements. The plan includes outfitting existing utility-owned solar projects with 200 megawatts of batteries, deploying 500 megawatts of new battery resources, and contracting for 150 megawatts of third party-owned storage — the last of which beat out new-build natural gas peakers in an request for proposals that just concluded.

        Institutional Investors 'See Energy Storage as Most Interesting Renewable' Option

        A new poll has identified energy storage as the most promising technology for institutional investors keen on renewable assets, amid plans by many to ramp up allocations. Nearly two-thirds of all asset owners and managers quizzed by the firm chose batteries and other energy storage technologies as the renewables subsector with the greatest potential. The appeal of storage rests on the "growing role" it will play in the European energy mix as renewables become more prominent.

      3. 100% Renewable Energy Needs Lots of Storage, This Polar Vortex Test Showed How Much

        100% Renewable Energy Needs Lots of Storage, This Polar Vortex Test Showed How Much

        Energy storage is a key piece of the power puzzle as cities, states, and supporters of the Green New Deal talk about a transition to 100 percent carbon-free energy sources within a few decades. Using energy production and power demand data, analysts at Wood Mackenzie showed how a 100 percent renewable energy grid, powered half by wind and half by solar, would have had significant stretches without enough wind or sun to fully power the system, meaning a large volume of energy storage would have been necessary to meet the high demand.

        Energy Storage Systems Can Help Calm Sea of Uncertainty

        Energy markets across the world are changing rapidly with the increase of renewables and the change to a more distributed energy network. Energy storage is key. The capabilities of large-scale batteries have expanded, allowing users to capture more value and create a powerful tool to manage energy needs. For manufacturers, energy storage systems can provide two major benefits: cost effective support to critical equipment onsite and mitigating utility risk.

        2018 Solar Installer Survey Reveals More than One-Third of Homeowners also Want Batteries

        EnergySage and NABCEP have released the results of their fourth annual Solar Installer Survey, which gathered responses from more than 870 local, regional and national residential and commercial solar installers from across the United States. In addition to the obvious finding that installers overwhelmingly support permanent tax incentives for clean electricity and storage, is the finding that homeowners are asking for batteries in addition to their solar panels. According to installers, more than one in three solar shoppers are also interested in a home battery, resulting in more solar-plus-storage installations in 2018.

        GHP Office Realty, LLC has completed the installation of 375 kW / 940 kWh of battery energy storage at their White Plains, NY headquarters. This project represents one of the largest energy storage installations in a commercial building in the state, and one of the first projects of its kind funded through a Con Edison Energy Efficiency program. The system features Lockheed Martin’s Gridstar 2.0 energy storage technology and Peak Power’s intelligent software platform, Synergy, which uses artificial intelligence to forecast moments of peak demand and stores energy for use during those peak times. GHP will receive significant long-term savings on energy costs and Con Edison’s burden will be lowered when demand on their grid is at its highest.

        Researchers Upcycle Plastic Waste Into Battery Anodes

        A team of U.S. researchers has presented a new approach to plastic waste treatment. A paper published by the American Chemical Society showed how researchers from Indiana’s Purdue University extracted pure carbon from plastic waste and turned it into anode material for lithium-ion batteries which powered a toy truck. The team claims that the method can be scaled easily. If so, plastic waste could find a hungry offtaker for its upcycled products in the PV industry, as co-located storage is becoming commonplace. The method produced battery anodes that perform competitively with commercially available products, the researchers claim.

        As energy storage becomes more economically competitive with more traditional forms of merchant generation, access to wholesale power markets is seen as an important addition to the technology's opportunities on the contracted side. However, questions remain about the effective implementation of the federal order that seeks to create consistent opportunities for storage to compete in wholesale energy markets. FERC is working through conflicting stakeholder comments regarding the compliance plans filed last year by six regional transmission operators and independent system operators related to Order 841 — FERC's directive on integrating energy storage into wholesale energy markets.

        Hawaiian Electric wants to move quickly on competitive energy solicitations it is preparing for Oahu, Maui and Hawaii Island, but state regulators have hit pause on the process while they consider how to move forward and prepare guidance for the utility. Phase 1 yielded seven solar+storage projects, and those power purchase agreements are now being reviewed by the Public Utilities Commission. But HECO did not acquire all the energy it sought in the first procurement round, teeing up a second round the utility wants to launch in May. HECO's most pressing need is to replace an AES purchased power contract that expires in September 2022.

        A New Evaluation Paradigm for Flexible Resources

        Important policy guidance was issued late last year that could impact the country’s investor-owned utilities, and it largely flew under the radar. The National Association of Regulatory Utility Commissioners (NARUC), the organizing and policy setting association for the country’s public utility commissions, issued a resolution document that sets the stage for what represents prudent assessment of energy storage and flexible resources. In the resolution, NARUC weighed in on the unique attributes of energy storage, stating that it represents a “fundamentally a different class of resource.” Accordingly, NARUC argued, utilities should develop “new modeling tools and new planning frameworks that allow for a more complete evaluation of flexible resources, such as energy storage."

        Sunrun has won a bid for 20 MW to participate in ISO New England’s 2022-2023 Forward Capacity Market. The bid means that Sunrun will be required to offer to the broader power grid 20 MW of power, 24 hours a day for the single year period. The company will be paid $3.80/kW/month, or $76,000 for the year. Sunrun notes that the capacity will be made possible by its Brightbox energy storage product line. Currently, this product is an LG Chem RESU. LG’s 48-volt battery comes with 3.3, 6.5 and 9.8 kilowatt-hour (kWh) ratings, and its 400-volt batteries offer 7.0 and 9.8 kWh ratings. Both AC- and DC-coupled versions are available. Sunrun noted they would need about 5,000 New England customers to meet the requirement.
