      California Utilities Try to Shift to Solar Storage… Tesla's Helping

      We have long lamented that while solar energy production is a mature generation technology that should be used in nearly the entire U.S., the inability of our electronic grid in much of the country to store solar-generated energy limits its use to when the sun is shining. This almost always requires a backup (usually burning natural gas) for those hours when the sun does not shine.

      Duke Energy Partnership with City, County May Avoid Third Power Plant

      ASHEVILLE — Momentum is building in the effort to avoid construction of one of three natural gas plants Duke Energy planned to build that would replace the coal plant on Lake Julian. At Tuesday’s joint City Council and County Commissioners meeting, members of the Energy Innovation Task Force, comprised of local government as well as representatives from Duke Energy, and Rocky Mountain Institute announced that they have begun to research options for the taxpayers and for the environment. They hope to present a two-year plan in the next few months before the City Council hears budget proposals.

    3. First Solar Proves That PV Plants Can Rival Frequency Response Services From Natural Gas Peakers

      First Solar Proves That PV Plants Can Rival Frequency Response Services From Natural Gas Peakers

      Last summer, First Solar and California grid operator CAISO ran a set of tests to show that utility-scale solar PV, instead of being a disruptive influence on the power grid, could actually help stabilize it. Over a series of days in August, First Solar slightly curtailed power output at a 300-megawatt solar farm in California, enabled its array of inverters, and plugged into CAISO’s system. It then orchestrated the plant’s output to follow CAISO’s automatic generation control (AGC) signals, respond to its frequency regulation commands, and use inverters for voltage regulation, power factor regulation and reactive power control.

      Battery-Powered in Escondido

      The nation's largest battery storage for energy is being constructed in Escondido — part of the shift away from fuel-burning power plants to cleaner energy, which can't be switched on when needed. San Diego Gas & Electric has contractors building the 30-megawatt lithium-ion array on the 1.5-acre Escondido lot that the company already owns. There's already a substation in that industrial park tucked into the southwest corner of where the SR-15 intersects Highway 78 (a second, 7.5-MW storage plant is being sited in El Cajon). The facility will contain 24 steel cabinets of lithium-ion batteries that can hold about 1.25 megawatts each.

      Younicos to Supply Centrica with 49MW Battery Storage Plant

      The deal is part of Centrica's wider plans to build a series of flexible power facilities, having secured 15-year agreements for over 500MW of new capacity, mainly gas-fired. The battery storage plant, which will be built at Roosecote in the north-west of England, will provide energy in response to peaks in demand. Roosecote is a large site having originally been built for a coal-fired plant, which has been retired. A gas power plant at the site was demolished in 2015.

      Power company AES Corp. may soon win approval for a 300-megawatt battery facility that would be capable of storing more electrical power than any such facility previously constructed. “It is the largest that we know of in the world,” AES Southland President Jennifer Didlo said. AES and its affiliates are simultaneously pursuing three major projects for the company’s Long Beach site, the Alamitos Generating Station, along the western bank of the San Gabriel River. The firm is also seeking approval from state regulators to build a brand new natural gas-fueled power plant and if permission is granted, AES would demolish its existing plant.

      Bloom Energy and PowerSecure Team Up for 50MW of Fuel Cells—and Some Batteries

      PowerSecure, the microgrid and backup-power provider bought by utility Southern Company earlier this year, is putting its money and technology into behind-the-meter fuel cells from Bloom Energy -- and trying out a fuel cell-battery combo in a select set of Home Depot stores to keep them running when the grid goes down. On Tuesday, these companies announced a strategic alliance that comes with a commitment from PowerSecure to acquire 50 megawatts of Bloom’s fuel cells. PowerSecure will offer them to its commercial and industrial customers through no-money-down installations, and sell the power they generate under long-term power-purchase agreements (PPAs) that lock in favorable prices for years to come.

      California Utility Turns to Tesla For Huge Battery Project

      It’s because of the Aliso Canyon disaster. Southern California Edison’s struggles after the closing of a key natural gas reservoir following a massive leak last year has led it to none other than electric car maker Tesla. Tesla on Thursday announced that it had won a deal to provide 20 megawatts of batteries to the utility to plug into one of its substations and provide energy during peak grid times. Tesla says the large battery installation would be able to provide enough power for 2,500 homes daily or 1,000 Tesla cars.

    13. To Beat City Heat, Use an 'Ice Battery'

      To Beat City Heat, Use an 'Ice Battery'

      Famously, Americans are the world’s most extravagant consumers of artificial cooling: We use more electricity for air-conditioning than the entire continent of Africa uses for, well, everything. And as global heat records keep falling and summers get longer and hotter—and as the use of A/C proliferates worldwide—that demand will continue to surge. The challenge of keeping cities livable as we chug toward our Venusian future is complicated by the fact that A/C use fuels rising temps, both directly and indirectly. To handle the increased power demands of hot summer days, utilities need to fire up those dirty, carbon-intensive “peaker plants” that emit an extra dose of climate-addling gases. Plus, because the electrical grid can’t just store the extra juice we need to crank the A/C when a heat wave comes, an enormous amount of energy is wasted on rarely needed capacity. “We have twice as much transmission as we need to meet our needs, if we were using it at a steady rate, day and night,” says Mark MacCracken, CEO of CALMAC, a New Jersey firm that specializes in thermal energy storage.

      A Texas Startup's Big Energy Idea: Storing Electricity Underground

      In a field in Central Texas, Aaron Mandell and his crew are running pumping equipment to bring a former oil and gas well back to life. But they’re not trying to extract black gold. Instead, they are developing a way to turn abandoned oil and gas wells into vaults for storing electricity. The concept behind Mandell’s startup, Quidnet Energy, sounds simple: pumping water deep into the earth to fill up the cracks in-between rocks that previously held fossil fuels. When the pressurized water is released, it acts like a spring as it races through a turbine-generator above ground, powering it to produce electricity.

      Energy Storage for Renewables can be a Good Investment Today, Study Finds

      Utility companies or others planning to install renewable energy systems such as solar and wind farms have to decide whether to include large-scale energy storage systems that can capture power when it’s available and release it on demand. This decision may be critical to the future growth of renewable energy. The choices can be complicated: Would such a system actually pay for itself through increased revenues? If so, which kind of system makes the most sense, and which features of the system are most important? If not, how much cheaper do storage technologies need to be?
