      Flexible Energy Storage Solutions

      Thousands of megawatt-hours of electrical energy squirreled away into utility-scale energy storage plants to cover the spread between generated renewable energy and the lowest reliable operating limit during the 10 a.m. to 3 p.m. “duck curve” period of the day — does this sound like a glimpse into the far future of major utilities across the United States and the world? But the future has already arrived at the Carolina operating companies of Duke Energy. The Duke Energy Progress Company, serving customers primarily in the eastern half of North and South Carolina, managed a whopping 106 GWh of excess energy in 2017, largely generated from utility-scale solar in North Carolina, using pumped hydro energy storage.

    4. NextEra: Solar and Wind Plus Batteries will be “Massively Disruptive” to Conventional Generation

      NextEra: Solar and Wind Plus Batteries will be “Massively Disruptive” to Conventional Generation

      Only one day after the Energy Information Administration projected that coal’s decline will slow, gas will dominate the future energy mix and that wind will peter out after the PTC ends, one of the nation’s largest and arguably its most successful power companies has a very different forecast for the future. In NextEra Energy’s fourth quarter results call, CEO Jim Robo dropped another bombshell, with his statement that solar and wind plus storage will be cheaper than coal, oil or nuclear, that this will be “massively disruptive to the conventional fleet” and that it will provide opportunities for developers well through the next decade.

    6. North Sea Rocks Could Act as Large-Scale Underwater Renewable Energy Stores, Study Finds

      North Sea Rocks Could Act as Large-Scale Underwater Renewable Energy Stores, Study Finds

      Rocks at the bottom of the North Sea may provide the perfect storage location for renewable energy, according to a new study. Excess power could be stored in the form of compressed air inside porous formations on the seabed, providing a reservoir that can provide energy on demand. This pressurized air can be released to drive a turbine, generating a large amount of electricity. This would allow green energy to be stored in summer and released in winter, when demand is highest.

    7. 'Unlayering' Peak Demand Could Accelerate Energy Storage Adoption

      'Unlayering' Peak Demand Could Accelerate Energy Storage Adoption

      The debate over energy storage replacing gas-fired peakers has raged for years, but a new approach that shifts the terms of the argument could lead to an acceleration of storage deployments. Rather than looking at peak demand as a single mountainous peak, some analysts now advocate a layered approach that allows energy storage to better match peak needs. The idea is beginning to gain traction with some states and utilities.

    10. Solar + Storage Half The Cost Of Gas Peaker Plants — 8MinuteEnergy

      Solar + Storage Half The Cost Of Gas Peaker Plants — 8MinuteEnergy

      S&P Global reports the cost of solar with battery backup dropped precipitously in 2018. Several tenders for solar plus storage came in at under $30 per megawatt-hour last year. Stand alone prices for installed battery storage — based on a 20 megawatt-hour system with 4 hours of storage — dropped 40% from the previous year to $357 per kilowatt-hour and are expected to keep falling. Bloomberg New Energy Finance projects a further 52% reduction by 2030. Such tumbling prices have led Wood Mackenzie to forecast that as the market for solar plus storage matures, it could put more than 6,400 MW of new natural gas-fired peaking capacity in the US at risk by 2027.

    17. As Utilities Fight Distributed Generation, Electricity is Getting Less Reliable

      As Utilities Fight Distributed Generation, Electricity is Getting Less Reliable

      Providing a stable supply of electricity is a core part of the mission of all utilities, and is demanded by the regulators who oversee them. And yet the security of U.S. electricity supply appears to be getting worse. Not only can solar and batteries supply backup power in the event of an outage, but distributed generation has the advantage of being closer to demand, and can improve the reliability of the grid. Microgrids further enhance this advantage, and are being actively investigated as a means to protect critical infrastructure during disasters.
