        NextEra Is on a Roll

        The largest wind and solar developer continues to grow, with projects paired with storage as it reaches 5.3 GW of contracted solar projects. And it’s making good money at the same time. In its third-quarter results, NextEra’s presence in the solar market is bigger than ever. Development subsidiary NextEra Energy Resources added 747 MW of solar contracts and 341 MW of battery storage to its backlog, almost all of which is in the post-2020 time frame.

      2. Federal Energy Regulatory Commission Approves First Compliance Filings on Energy Storage Rule

        Federal Energy Regulatory Commission Approves First Compliance Filings on Energy Storage Rule

        The Federal Energy Regulatory Commission approved the first two orders implementing Order 841, which aims to break down market barriers to electricity storage. FERC found that the tariffs for SPP and PJM generally satisfy Order 841’s directive allowing electric storage resources to de-rate their capacity to meet minimum run-time requirements, but the commission also found that neither market includes minimum run-time requirements for resource adequacy and capacity in its tariff. So FERC directed the two market operators to submit tariff provisions reflecting their rules and practices regarding resource adequacy minimum run-time requirements and capacity minimum run-time requirements for all resource types.

        Energy Storage Fire Safety Codes to go Into Effect in New York Next Month

        Supporting New York’s state goals of reaching 3,000MW of energy storage by 2030 - equivalent to 40% of today’s electric demand - codes for the safe installation of energy storage systems will go into effect on a permanent basis after 1 November. The issue of fire safety in relation to the deployment of stationary energy storage systems in New York, particularly in the US state’s densely populated urban areas, has been considered to have held back what has otherwise been a hugely fertile state for clean energy.

        UK Firm Announces Plans for First 'Liquid to Gas' Cryogenic Battery

        British battery pioneers plan to build Europe’s largest energy storage project using a cryogenic battery that can store renewable energy for weeks rather than hours. The device will be built on the site of an old fossil fuel plant in the north of England to power up to 50,000 homes for up to five hours. Unlike traditional lithium-ion batteries, which typically store electricity for a few hours, the “cryobattery” will be able to store energy for months.

      5. The Biggest U.S. Battery Is 16 Years Old

        The Biggest U.S. Battery Is 16 Years Old

        The biggest battery in America has been quietly at work for almost 16 years in a far more remote corner of America: a warehouse in central Alaska. The 46-megawatt battery, in Fairbanks, uses a chemistry that’s largely gone the way of fax machines. It’s old enough that its operators can’t find replacement parts for some components. But it still works, keeping the lights on in the city of 32,000 near the Arctic Circle, preventing 59 blackouts last year alone.

        In a deal spanning 20 projects, seven states, two power markets and more solar than the entire state of Florida has installed to date, ACCIONA has agreed to a deal with Tenaska to acquire 3 GW of utility-scale solar and 1 GW of co-located solar and energy storage. Specially, ACCIONA envisions commissioning eight projects by the end of 2023, adding around 1.5 GW of peak capacity to its North American renewable energy portfolio.

      7. Is Energy Storage Finally Ready To Tackle the Wind Sector's Biggest Challenge?

        Is Energy Storage Finally Ready To Tackle the Wind Sector's Biggest Challenge?

        Now that wind energy has gone mainstream, the big challenge is how to squeeze the most kilowatts out of a wind turbine. The task is more complicated than simply increasing the size and efficiency of the turbine. People—and businesses—need electricity when they need it, but the wind blows when it will. The result can be an undersupply of wind energy during peak demand periods and an oversupply at other times, especially at night. However, more economical energy storage technology is coming online, and it's having a powerful impact on both the wind and solar energy markets.

        New York City Trades Gas Plants for the World's Largest Battery

        The New York State Public Service Commission (PSC) has approved a 316 MW / 2528 MWh (that’s 8 hours!) energy storage facility to “provide peak capacity, energy, and ancillary services in New York City while enhancing grid reliability”. Ravenwood Development (owners of the current gas plants at the site) plans to build out the project in three phases – 129 MW, 98 MW and then 89 MW – with the first phase complete by March 2021. If they deploy all 2.5 GWh of energy storage, they will demolish 16 existing gas peaker plants, only two of which are currently running.

        FERC OKs PJM, SPP Storage Plans, Sets Separate Proceedings for Minimum Run-Time Requirements

        The Federal Energy Regulatory Commission (FERC) on Thursday gave its first two approvals to grid operator plans to implement its energy storage order. PJM Interconnection will implement most of its plan by Dec. 3, while participating in a separate proceeding to evaluate the fairness of its 10-hour duration requirements for storage to participate in its market. Southwest Power Pool will implement its plan in nine months, as FERC regulators approved extra time for the grid operator to implement a new settlement management system.

        Let's Kill 'Utility-' or 'Grid-Scale' Storage

        Ask people how they segment the energy storage industry, and you'll often hear them divide it between customer-sited or behind-the-meter storage and "utility-"or "grid-scale storage." But if you then ask them what they mean by "utility-scale," you can't get a clear answer. Is it 5 MW, 10 MW, more than 20 MW? Do they mean "front-of-meter"? Or connected to the bulk transmission system? No, we're not calling for the end of the large-scale storage industry. We're saying that distributed, smaller-scale storage can provide all the same value to the grid that large-scale storage can and should be explicitly encouraged to compete on playing fields that policymakers have leveled everywhere.

        Energy Storage with Second Life Batteries by ENGIE and Umicore

        On October 8, 2019, an industrial 'second life' battery system was first put into use in Belgium. The system consists of 48 used batteries from electric cars, and now forms one large storage battery of 1.2 MW or 720 kWh. Now that the electric car is gaining popularity, the question arises as to what will happen to all batteries once the cars are no longer being used; the partnership between Engie and Umicore will develop applications for these ex-EV batteries.

        California Blackouts: Keeping the Lights on with Solar Energy

        Hundreds of thousands of homes in California lost power early on Wednesday as windy, dry weather increased the risk of fire, prompting the electric utility, PG&E, to shut down the grid to avoid any chance of the type of power-line accident that sparked the deadly wildfire in the small town of Paradise less than a year ago. It may take days for the power to come back on. But at some homes, solar and battery storage systems are keeping the lights on.

        Go Big, Go DC: An In-Depth Look at DC-Coupled Solar-Plus-Storage

        As the costs of solar PV modules continue to reduce, and those of batteries follow a similar downward trajectory, solar-plus-storage is in growing demand among utilities and solar developers. To further push down the levelized cost of energy of solar-plus-storage and maximize the amount of MWh of solar-generated electricity that can be fed into the grid, energy suppliers and developers are turning to direct current (DC) coupling these installations. Compared with alternating current (AC) coupling, DC coupling the PV array and the battery storage system in front-of-meter installations, such as utility-scale plants, is a much newer, less standardised approach.
