      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.

    2. How Solar and Batteries Could Help California Manage Fire-Prevention Grid Shutdowns

      How Solar and Batteries Could Help California Manage Fire-Prevention Grid Shutdowns

      As Pacific Gas & Electric and California regulators grapple with how to manage the potential for widespread fire-prevention grid shutdowns this summer, clean energy advocates are demanding a role for solar, energy storage and microgrids as part of the solution set. But, as with so much related to the state’s de-energization plans, there’s much uncertainty over how to balance two potentially competing imperatives: the need to move quickly to mitigate potential grid emergencies this coming summer, and the need to find long-term fire mitigation methods that also match the state’s clean energy goals.

      Oil Supermajor Shell Acquires Sonnen for Home Battery Expansion

      Shell will acquire German startup sonnen, staking a claim on the home energy storage market and further expanding its ever-increasing footprint in the clean energy industry. Sonnen distinguished itself in the early home-storage market, with thousands of units deployed across Germany, and a notable presence elsewhere in Europe, the U.S., and Australia. Besides storing solar power for homeowners, sonnen aggregates its installations into controllable networks of grid resources.

    4. A New Evaluation Paradigm for Flexible Resources

      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."

    5. How Market Rules Are Holding Back Energy Storage

      How Market Rules Are Holding Back Energy Storage

      Energy storage is surging. The U.S. Energy Storage Monitor Q4 2018 estimates that installations totaled 338 megawatts in 2018, and will grow to 3.9 gigawatts by 2023, much of it front-of-the-meter utility-scale projects. But wholesale market rules are organized around legacy assets, restricting storage from selling all potential services, which in turn limit storage’s wholesale revenue streams. Recognizing these barriers, the Federal Energy Regulatory Commission issued Order 841 to stimulate access to wholesale markets. At the end of 2018, FERC-regulated independent system operators responded with their implementation plans.

      El Paso Electric wants to build new natural-gas generation to meet its summer peaks, but it also selected solar and, unusually for Texas, energy storage resources. The portfolio's heavy battery component breaks new ground for Texas, a massive energy market where energy storage has had an exceedingly difficult time breaking in, as previously reported by GTM. A few battery projects have moved forward as research efforts, and some have succeeded with creative business models, but never before on the scale of 100 megawatts.

      AES Corporation launched the world’s largest battery plant paired with solar generation Tuesday, on the Hawaiian island of Kauai. The Kauai Island Utility Cooperative is finishing up commissioning for the Lawa’i Solar and Energy Storage Project, which combines 28 megawatts of solar photovoltaic capacity with a lithium-ion battery capable of storing 100 megawatt-hours. The battery alone holds more energy than all but one other U.S. plant: the 120 megawatt-hour facility AES built in Escondido in 2017. Taken as a whole, Lawa’i’s storage capacity outranks any other operational solar-paired battery system in the world, according to Wood Mackenzie Power and Renewables.

      Mexico energy authorities have been developing an energy storage strategy to balance out the country’s recent surge in solar power plants. What appears to be the first and largest battery to come online, though, does something else entirely. The 12-megawatt/12-megawatt-hour device switched on in October to deliver reliability and power quality at a 130-megawatt microgrid serving an automotive factory campus in Monterrey. The device handles spinning reserve, voltage support and frequency for the fully self-contained electrical system.

      ARPA-E Funds Research on Energy Storage That Can Last for Days

      Long-duration energy storage — batteries or other technologies that can store energy for at least four hours of continuous operation, or possibly even longer — accounts for a minority of the grid-scale energy storage deployed today. There are many reasons for this, including the cheapness and relative reliability of lithium-ion batteries for short-duration applications. As well as the, shall we say, less than stellar record of long-duration battery startups that have gone bankrupt or failed to deliver on their promises.

      Residential solar provider Sunnova is returning to Arizona after a period of regulatory tumult, and this time, it's bringing batteries. The privately held company fast-tracked its SunSafe solar-plus-storage offering in the aftermath of Hurricane Maria, which left thousands of Sunnova customers in Puerto Rico without power even if their solar panels survived undamaged. Since then, the company has expanded its hybrid product to California, Massachusetts and now Arizona. That puts Sunnova into competition with Sunrun’s growing BrightBox product, and whatever is left of the company that used to be SolarCity.
